METHOD OF AND APPARATUS FOR COMMUNICATING USER RELATED INFORMATION USING A WIRELESS INFORMATION DEVICE

Abstract: A mobile telephone which can supply or post 'pre-answer' information which the device owner considers of relevance to a potential call recipient. This information enables a potential call recipient to be given useful information about a potential call before actually answering that call. The information is dynamic, unlike Caller ID information. Examples include: information about the subject of an intended voice call, a mood, a current activity, part or whole of a schedule of meetings or events, information about the urgency of an intended voice call, personal information, expected call duration, commercial inducements to a consumer to answer a call (special offers, loyalty points, etc.), location information.

Description: METHOD OF AND APPARATUS FOR COMMUNICATING USER RELATED INFORMATION USING A WIRELESS INFORMATION DEVICE BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method of an apparatus for communicating user related information using a wireless information device. The term 'wireless information device' used in this patent specification should be expansively construed to cover any kind of device with one or two way communications capabilities and includes without limitation radio telephones, smart phones, communicators, personal computers, computers and appHcation specific devices. It includes devices able to communicate in any manner over any kind of network, such as GSM or UMTS mobile radio, Bluetooth, Internet etc. Description of the Prior Art Current generation wired and wireless telephones can indicate to a caller the status of a call recipient in only crude and potentially ambiguous terms: for example, when a caller makes a voice call, he or she might receive one of five different responses: (a) the desired call recipient answers; (b) there is no answer; (c) there is an engaged tone; (d) the call gets put through to a pre-recorded voice mail message or (e) the call gets diverted to someone else. If the intended call recipient does not actually answer the call, then the caller has no idea why the call was not answered: for example, is the intended recipient in fact there but too busy to answer? Could a different number have been dialled to connect successfully? Conventional so-called 'Presence' systems are the subject of considerable interest at present and partly solve the above problems. The intent of Presence systems is to show the status of the prospective call recipient to a calling party - for example, giving information about whether the intended call recipient is busy, in a meeting, contactable on a mobile phone or land line etc. Reference may be made to RFC 2778 'A Model for Presence and Instant Messaging' February 2000, The Internet Society. Prior art Presence systems have not however been extended to cover the idea of the calling party indicating its own status, such as the subject of the intended call or its urgency. Reference may also be made to conventional Instant Messaging (TM) systems, which allow a party able to participate in IM to indicate its status by selecting a pre-defined status flag (e.g. Out to Lunch; On-line etc.) Because these status flags show merely the status of a party, they are aimed at mforrning a party wishing to message that party whether doing so would be appropriate, and are therefore similar to the conventional telephony Presence systems described above. Hence, both prior art IM and Presence systems share a presumption that the critical information to convey, prior to the main communication commencing, relates to the status of the entity which is the target of communications (e.g. whether they are reachable and if so how). This is an essentially asymmetric weighting of significance and ignores entirely the possibility that the person seeking to initiate communication (e.g. commence a voice call) can also provide the target (the call recipient) with useful information prior to the main communication commencing. Caller ID systems partly address this: they enable a called party to see the telephone number of the person calling. Caller ID systems are increasingly popular, since knowing the identity of the caller can be very pertinent to a decision to accept a call or not. Where the called party's device can store a database of numbers, the caller ID information can be matched against database entries, so that the called party's device can display the actual name of the person calling. At the most basic level, mobile telephone users use the caller ID to screen their calls so that, based on a number of factors relating to themselves (i.e. location, current activity etc.), they can look at the caller ID and make a number of assumptions about the identity of the caller and then take a decision regarding answering the call. However, users are increasingly feeling compelled to answer calls simply because they know that the mobile telephone is with them no matter where they are. Users are answering the mobile telephone even when it is not convenient for them. They are now trying to take various steps to control the reactive behaviours implicit with owning a mobile phone, despite the availability of Caller ID. For example: • Some buy two mobile telephones; one is for personal use, the other for work. • Some are insisting that the phone is turned off outside of work hours. • Some simply decide, based on the Caller ID, that if no name is shown with the call — that the call is probably unimportant because they don't recognise the number. Conversely others interpret this same factor as indicating a potential emergency call. Hence, the inherent limitations of Caller ID seriously restrict its practical utility. Through the convergence of communications and computing, a new generation of intelligent communications devices, often referred to as smart phones or communicators, is being brought into being, utilising operating systems and related applications such as the Symbian OS platform from Symbian Limited of the United Kingdom. Wireless information devices based on the Symbian OS platform offer the promise of being 'smarter' than current generation GSM phones in being able to offer multiple advanced, robust client based applications. However, prior to the present invention, even these advanced wireless information devices would have been no more capable than existing phones in terms of providing rich information about a call to a call recipient prior to the call being answered. SUMMARY OF THE PRESENT INVENTION In a first aspect of the invention, there is a method of communicating user related information using a wireless information device in which a caller using a first wireless information device enters into the device information of potential relevance to a call recipient, the information being of a kind which varies; the method comprising the step of transferring that information to a second wireless information device controlled by the call recipient, such that the call recipient is automatically provided with the information prior to accepting or answering a voice call from the caller. The invention therefore envisages wireless information devices which can supply or post 'pre-answer' information which the device owner considers of relevance to a potential call recipient. This information enables a potential call recipient to be given useful information about a potential call before actually answering that call. Examples of the kinds of 'pre- answer' information which a calling party can input include without limitation the following: information about the subject of an intended voice call, a mood, a current activity, part or whole of a schedule of meetings or events, information about the urgency of an intended voice call, personal information, expected call duration, commercial inducements to a consumer to answer a call (special offers, loyalty points etc.), location information. The information must however be dynamic (i.e. potentially variable) and hence does not cover persistent information, such as conventional caller ID information. From an operator revenue perspective, allowing a calling party to enrich their communication with pre-answer information is more potent than conventional Presence since a calling party can be expected to pay for this additional data service. Conventional Presence systems require input from the call recipient and, arguably, will need to be paid for by that call recipient and, as such, are likely to be difficult to establish commercially. Revenue models based on the principle of the 'calling party pays' have tended to be more successful than those in which the called party has to pay. The invention may also embrace the conventional Presence situation in which a caller can be automatically provided with Presence information relating to the called party prior to initiating or starting a voice call with another person. Hence, the present invention may cover the symmetric situation of, prior to a voice call starting, a caller being give Presence information about the called party ('pre-call information') and the called party being give Presence information about the calling party ('pre-answer information'). The format of the information can be text, or other media formats, such as images (e.g. a digital picture of the calling party's current location taken with a digital camera on the calling party's device), icons (e.g. heart icons as pre-answer information to a boyfriend); or animated graphics (e.g. a Lara Croft cartoon figure; a personal avatar). A user could have several different sets of information which it selects manually or automatically depending on other data (e.g. the person called). Hence, a user could have one personal avatar figure for calling friend, and a different one for calling family. Icons and graphics can be selected from a menu of pre-stored options and may also be obtained from a remote server, in the same way as ring tones are currentiy downloaded. Just as custom ring tones have been highly effective in enabling mass customisation of mobile telephones and have generated significant and highly profitable revenue for network operators and ring tone suppliers, so can pre-answer icons and animated graphics. Pre-answer information may accompany or replace the call recipient's ring tone, in much the same way that caller ID does. It may relate specifically to a call (e.g. the subject of the call) or be more general (e.g. a mood). The information will typically precede an intended voice call, although the voice call itself may not occur for a variety of reasons. As noted above, in conventional Presence systems, information is generated for or posted by a person who may be called; this can influence and inform a caller making an outgoing call to that person as it can be read and used by that caller to assess the situation of the person to be called. But the present invention goes beyond conventional Presence because the information of relevance can also be posted by a person doing the calling: it can influence and inform the person receiving an incoming call as it can be used by that call recipient to assess the subject of the call, its urgency, the mood of the caller and any other item input by the caller which more fully defines the context of the call. As will be described later, pre-call and pre-answer information can be generalised to a Nirtual Presence', which can take the form of a customisable virtual avatar and can also represent facts about any user, i.e. both callers and targets, in any messaging context, and hence is not limited to use prior to a voice call. Hence, Nirtual Presence could be used not only to enrich voice communication, but also data communication such as chat and instant messaging. The present specification goes beyond conventional Presence by suggesting new categories of information which can be posted/input (such as moods and personal avatars) and new user interaction functions (such as the 'Convert to Text', 'Hold and Mute', 'Doodles' and 'Evolvlcons' described later). These innovations are independent of the insight of providing dynamic pre-answer information to a call recipient (e.g. defining the subject of an intended call). Hence, this specification discloses multiple innovations which are not limited in their application to circumstances where pre-answer is also used. Scenarios If we take a situation in which Alice knows Bob, Bob might post a 'mood message' saying "I need cheering up" on his device. Alice decides she wishes to call Bob; when she looks him up in the contacts manager application on her wireless information device, and selects a 'make voice call' function, Alice's device initiates communication with Bob's device. Prior to opening a voice channel, Bob's device returns as data (e.g. peer to peer SMS, Smart Message (a Nokia format) or data packet such as IPv6) his pre-call 'mood message', so that the message "I need cheering up" automatically appears on AUce's device. The device then prompts her whether she wishes to proceed with the voice call and/ or post a responsive 'mood message'. She decides to do both; first she enters the message "I'll cheer you up Bob" and then initiates the voice call. Bob's device shows the "I'll cheer you up Bob" pre- answer message from Alice, so Bob immediately answers the call, already having a positive expectation about the likely social interaction with Alice. Another situation might be that Bob posts a pre-call message saying "Anyone want to go to a cinema tonight?" on his wireless information device. He makes that information available to anyone listed in a 'Friends' category in his contacts database, held locally on his device. Alice decides co-incidentally to call Bob; Bob's device recognises Alice as belonging to his 'Friends' class (e.g. through caller line ID, or a unique ID associated with Alice's device which Bob's device knows) and so automatically sends Alice's device the "Anyone want to go to a cinema tonight?" data prior to initiating the voice call. AUce in fact wants to have a long chat with someone tonight, and decides that Bob is not the right person to caU right now. Bob might also post a pre-caU message saying "Now in a meeting with my boss tiU 5pm". Then AUce, reading that information automatically provided to her when she selects Bob's name in her telephone appHcation, can decide to not proceed with the voice caU at that time. But perhaps if AUce knew Bob's boss, and wished to interrupt their meeting precisely so she could speak with both of them, she would caU Bob knmediately. Knowing the situation of a caU recipient in this way also aUows the caUer to override a caH diversion function or caU bar which has been set by the required caU recipient. Suppose Bob is in an important meeting and decides to divert all cans from his voice based wireless information device to voice mail. Alice faces an emergency and must reach Bob. Alice can see that Bob is in an important meeting from the pre-call information he has posted. But she can do one of two things to reach Bob despite Bob's attempt to remain uninterrupted. First, she can send the pre-answer words 'Emergency! Please answer' to Bob's device, which can be programmed to beep or otherwise alert Bob when a message comes through with certain defined key words Hke 'emergency'. Bob reads that message and then immediately caHs AHce. Or Alice could be given by Bob rights to override his caU diversion, which she can use at her discretion, with that discretion being exercised appropriately since AHce can see Bob's situation defining information. Override rights can be given to close friends and family and also to emergency services. As noted above, the subject of an intended telephone caU can also be defined by a caUer as the pre-answer information. As an example, say AHce and Bob have an argument. Bob might ordinarily try to caU Alice, who would likely not answer. With the present system, Bob can open his telephone appHcation on his device and choose AHce from his contacts Hst; instead of just dialling out immediately, the appUcation can present an on-screen prompt to enter a subject for the caU, an indication of its urgency and how long the caUer thinks the caU might last and to select a suitable graphic. Bob enters into the subject field 'I'm sorry', indicates that its urgent and sets the caU time to maximum. He selects a heart graphic. Bob then initiates the caU; AUce's device rings and she can see from a display on her device that the caU is from Bob, the subject is "I'm sorry", the time duration is set to maximum and there is a heart graphic. The expected time duration is represented by a clock icon (which can show one of several variants, for example, a 'quick caU' icon, 'long chat' icon etc.), although the user can alternatively just state in the subject field 'Quick caU'. AUce decides it's time to accept Bob's apology and answers the caU. As noted above, the pre-answer information may be sent as data prior to a voice channel being opened, for example as SMS data, a Smart Message or packet data (e.g. in IPv6 or other packet based system. The information is then displayed on the target device, together with various user prompts, including "Proceed with voice caU?" and "Post reply message". This data handshake can carry not only information which AHce or Bob have themselves entered into their devices, but also information which the device itself is aware of and is automaticaUy entered; location information is one example of this. This information can be thought of as being 'impUcidy entered' by Bob or AUce and references to an entity entering information cover both expUcit and impUcit entering; hence automatic entering of Bob's location information is an example of Bob impUcitly entering that information. The information must however be dynamic (i.e. potentiaUy variable) and hence does not cover persistent information, such as conventional caUer ID information. In another example, say AUce is already on a voice caU to Sam; Bob selects AUce's name from his telephone appUcation and a data handshake between Bob and AUce's device foUows. This suppHes to Bob's device the information that AHce is already making a voice caU; if Bob has appropriate access rights, his device is also informed that AUce is talking to Sam and prompts Bob to choose whether or not to interrupt AHce and Sam to join their conversation. In another implementation, the pre-caU information is stored not only at a local device but is also posted to a remote web server, which a calling device may have access rights to poll. In essence, prior to making a voice caU, a device connects first to the web server to coHect any pre-caU information posted there. Similarly, pre-answer information can be posted to the remote web server and be downloaded by a target device. This approach may be particularly attractive in a VoIP system, since the web server could be integral to the VoIP network and a server caU is just part of the necessary voice caU routing anyway. Further, holding pre-caU and pre-answer data on a server (as opposed to keeping it just on a cUent) aUows the data to be seen by one party even when the other has a device which is out of coverage or off/busy. Conversely, where a GSM system is used for the voice caU, then a separate connection to a web server to download situation defining information is a considerable extra overhead and the peer to peer system based on SMS or Smart Messaging is preferable. An alert may be sent to a person when the information describing the situation of another person alters in a way defined by the person. For example, Bob posts a pre-answer message "Please don't disturb" onto his device which AUce then reads on her device when she selects Bob's name from her wireless information device's contacts manager just prior to making a voice caU to him. AUce doesn't need to interrupt him. So she programs her device to alert her when Bob's "Please don't disturb" message is removed by Bob. When that happens, AHce is alerted and can proceed to make the caU to Bob. The foHowing extension to the previously described ideas is also within the scope of the present invention: say Bob wishes to speak with AUce about going out tonight. Bob enters as pre-answer information the subject Une 'Dinner tonight?' and the quick caU duration icon and initiates the caU to AHce. AHce is in an important meeting and has set her device to flash an on-screen indication of the subject and caUer name of any caHers; she sees Bob's name and his subject Hne. She decides she cannot take a voice caU but can take a few moments to send a text response. She then responds to the incoming caH by selecting a 'respond with text message?' option, rather than an 'accept voice caU?' option shown on her screen's device. She is then given a field into which she can type a message; that message is then transferred as data to Bob's device for display on his screen. Bob responds with his own reply and the data communication is then terminated. The voice caU part of the caU has not in fact commenced at aU — the communication has been handled entirely using text data transfer. In a second aspect, there is a wireless information device controUed by a calHng party and programmed (i) to allow information to be entered into it, the information being of relevance to a caU recipient with whom the calHng party wishes to communicate, and being of a kind which varies, and (H) to transfer that information so that it can be read by a second wireless information device controUed by the caH recipient; whereby the caH recipient using the second device is automaticaUy provided with the information prior to answering or accepting a voice caU from the calling party. In a third aspect, there is software for a wireless information device which, when running on the device enables the device to perform as a wireless information device as defined in the second aspect. In a fourth aspect, there is a method of generating revenues relating to the use of an appHcation on a wireless information device, in which the wireless information device is as defined above. CaUing parties might therefore pay a flat fee (e.g. monthly or quarterly) to their wireless communications provider in order to enjoy the functionaUty defined above. In a fifth aspect, there is a method of generating revenues in which a caUing party pays to perform the inventive methods defined above. CalUng parties might therefore use the functionaUty defined above on a pay-as-you-go basis to their wireless communications provider. In a sixth aspect, there is method of aUowing a data file to be downloaded, in which the data file is capable of being used as information which is (i) sent by a caUing party to a caU recipient prior to answering or accepting a voice caH from the caUing party, and (H) is of relevance to the caU recipient with whom the caUing party wishes to communicate, the information being of a kind which varies. The data file can be an icon or animated graphic. Further details of the invention are contained in the claims of this specification. DETAILED DESCRIPTION The present invention will be described with reference to a project from Symbian Limited of London, United Kingdom, caUed the Voice ++ project. The Voice ++ project has identified two key mechanisms for the enhancement of the mobUe telephone experience, namely: • Virtual Presence • Asynchronous communication Virtual Presence Virtual Presence offers the user an opportunity to define a virtual identity for themselves. Through customisation of their 'look' (i.e. how they are perceived by another user) they can be more than just a Hst of numbers in someone else's Contacts Ust. CaUers can see the target's (i.e. caU recipient) Virtual Presence in their Contacts Ust. Targets can see the caUer's Virtual Presence. Expressing personaUty is in itself a highly attractive feature for specific segments of the market, i.e. the Teens. However Virtual Presence is not simply static information of a 'look and feel' nature. It shows not only the personal expression of another user's identity but also has the potential to show a whole wealth of information about the user: • The user's Mood - (e.g. for a target: 'Don't Disturb', 'Working', 'Out Partying', 'Commuting' etc. — these can encourage the caUer to either: call immediately, caU later, send a text or voice message, not caU at aH etc. For a caUer: 'Urgent! Please pick up' will encourage the target to pick up). • Their location — of varying granularity — i.e. 'London N17', 'Salisbury's — Clapham'. • Phone Status - i.e. 'Busy', 'Available', 'No/poor network coverage', 'No battery' etc. • Messages from the caUer or target — 'Working from home', 'Out on the town', 'Out of the office till 2 nd Feb 2001' etc. • PIM information - i.e. during the day, data avaHable from the Calendar appHcation may indicate which meeting the caUer or target is currently in. • The preferred communication mechanism — as indicated impUcitly or expUcidy through the Mood and caUer Messages etc. • The Network Situation — i.e. Name of network operator, CaU charges at the intended time of the caU etc. With games and Third party appHcations the attractiveness and usefulness of such a Virtual Presence has the potential to expand greatly. The Detail At its most basic level, Virtual Presence offers the caUer information about the availabiHty of the target. In turn the target may see more than simply the name of the caUer. By putting his phone into a specific Mood, the target can specify their availabiHty and therefore provide the caUer with information about how they would like to be contacted, i.e. 'Only available for text chat' (this automaticaUy suggests the use of text for communication), 'By aU means ring me' etc. In addition, the status of the mobUe itself can provide the caUer with information about whether now is a good time to caH, i.e. the mobUe may be in 'By aU means caU me' Mood but the target is currently in a caU. The caUer may choose therefore to activate Ring Back (See Ring Back Service Description) or simply try again in a few minutes. In this way the caUer and target can automaticaUy exercise an element of control over the communications which to date has not been possible. Illustration: By the target putting the phone into a "Don't Disturb" Mood, the caUer can be prompted to send a voice or text message instead. Depending on how the target has specified the behaviour of 'Don't Disturb' they may receive a prompt (a short vibration) that a message has been left, or no prompt at aU in which case the next time they switch out of 'Don't Disturb' Mood they wiU be notified that messages have been left for them. NB: This should not be taken to mean that a Mood such as 'Don't Disturb' would prevent caUs being placed, rather it is simply the case that the target is advising the caUer to leave a message rather than caU. This degree of functionaUty alone provides a major part of the control that users are looking for. Depending on the Mood settings they use, the target can leave the phone on, i.e. can use it for their own purposes but can ensure (assuming social protocols are foUowed — see Social Protocols discussion) that they are contactable as and when they want to be and in the manner that they choose. At the most basic level therefore, the mobile telephone can ship with a smaU core set of Moods which the user can easUy switch between much in the same way as mobUes currently offer a core set of profiles which (in the main) control the physical behaviour of the phone. Taken a step further however the customisation of these Moods by the caUer and also the target enables them to extend their Mood into a rich Virtual Presence rather Uke Avatars avaUable on the Internet (i.e. with variations of ring tones, graphics, animations, messages etc.) Both parties can offer rich, dynamic and fun information. In the same way that Ring Tones and graphics can be downloaded, supporting Avatar type data could also be avaUable. WhUe it is suggested that the mobUe ships with a smaU core set of Moods, it is Ukely that users wiU develop several Moods with the same underlying preferences but which display quite different Moods, i.e. Meeting and Clubbing. In both instances the user might not want any communication other than text but the information provided for the caUer (or target) impHes radicaUy different states. Users would Ukely be keen to provide a virtual representation of themselves. Behaviour on the Internet suggests that some segments wiU make a great deal of effort in creating a Virtual Presence. While this behaviour is indeed PC based, in the main we can already see such personaUsation behaviour occurring in the mobUe space too. As described above some segments of the market wiU go to great pains to personaHse their phone, with ring tones, hard covers and on screen pictures. Given an easy customisation environment some segments of the market wiU extend this behaviour to the mobUe virtual world. Users are already using their mobile to make effective use of 'Dead Time' by the creation of text messages and fiddling with settings. With appropriate functionaUty it is highly Ukely that the desire to 'play' with their Virtual Presence wiU be equaUy attractive. This factor encourages the creation of new Moods which not only provide users with a more meaningful presence and greater control of their mobUe but also inherently provides users with a far richer standard of Pre-caU and Pre-Answer information. Ultimately the Internet and mobUe based Avatars wiU probably merge and a user wiU have a Virtual Presence the complexity of which is purely dictated by the viewing device and its settings. Social Protocols The value of Moods is to some extent dependent upon adherence to the social protocols that such a service impHes (i.e. the need for the caUer to respect the Mood indicated by the target and to behave accordingly, and vice versa) These social protocols are already weU estabUshed in face to face communication: the demeanour of the target can be perceived and judgements made by the person about to initiate the communication as to whether or not now is a good time. These protocols are recognised and as relationships get estabUshed people know the extent to which they can break these protocols. Moods simply provides a similar degree of information in the virtual space. The Avatars visible to the caUer and target may in fact be tailored. AppUcations which can reflect the relationships with contacts facUitate the development of emotional messages (See Evolvlcons Service Description). Pre-caU and pre-answer information can also grow as the relationship grows or could dictate that specific caUers are always sent to VoiceMatl. People customise their Instant Messaging presence according to who can see that presence information and some people wiU spend time customising ring tones etc. for specific people. It is predicted that, for key individuals in particular, users wih personaHse their Virtual Presence too. Clearly there wiU be instances where it is desirable to over ride the Mood specified by the target (i.e. in emergencies a caUer may ignore the request for text only and may still place a phone caU.) It is not the Uitention of Voice ++ to suggest that Moods are enforced: there are always exceptions to the Moods and the target would be unwise to create a Mood which prevents an emergency caU from reaching them. The Moods are there as recommendations to the caUer. And the target can always make use of features such as Hold (see later) to take back some of the control. The extent to which the target insists that the Moods are adhered to is down to individual personaHty. It could for example be encouraged through the addition of a short message accompanying a Mood, (i.e. if in 'Don't Disturb' Mood, the target may also add a text message as part of their Virtual Presence which says "and yes I do mean it ©"), a message that everyone (or specific violators of the metaphor) see. Asynchronous Communication Users akeady engage in large amounts of asynchronous behaviour. Text messaging is widely acknowledged as a major use of the mobUe phone. Despite the tedious nature of inputting the text itself, users stiU engage in brief, asynchronous chat. It is seen in use not only during 'Dead Time' when a caU is inappropriate or impossible but on occasions when an entire conversation is unnecessary or undesirable. Being able to transfer information at a point in time convenient to the user places the user back in control of their mobUe. This chat takes a variety of forms being anything from inane chatter about what they are doing or have done to the transfer of information i.e. a phone number, location instructions etc. to another person. The spoken nature of voice messaging provides the user with an even faster means of having these asynchronous 'chats' with other people, although clearly there wiU be situations where text is stiU preferable. However, with the development of speech to text technology, voice messaging could at the very basic level simply be viewed as the input mechanism, i.e. if the caUer is in 'Text Only' Mood this message could be turned into text. Nuance and intonation forms a key part of aural messages and this would be lost in current conversion techniques, therefore, forcing the conversion as part of a Mood may not be desirable. A key issue for the user experience in the creation of asynchronous data, be it verbal or textual, is that it should not be tied to any specific appUcation on the mobUe. We naturaUy multi-task and the creation of a 'Doodle' (see later) in one location on the mobile for example should not prevent that easHy becoming a text message. What this means for Voice ++ The foHowing Services are of key importance in the fulfilment of the aspirations described above: Virtual Presence: • Pre-CaU — encompassing various elements including: Moods; Convert To Text, Phone Status, Doodle, Information Management, Ring Back, plus Avatar type data etc. • Pre-Answer — encompassing various elements including Moods; Convert To Text, Doodle/Post, Information Management, Advanced VoiceMaU including: CaU Screening, Pause/Play/Reply to VoiceMaU and Hold as weU as Avatar type behaviour. Asynchronous Communication: • Voice Messaging • Doodle. These two areas satisfy the key requirement identified during the Voice ++ research, namely enhancing the caU experience such that the user perceives themselves to be in control of their mobUe telephone. Service Descriptions The foUowing Service Descriptions satisfy the key requirement identified during the Voice ++ research namely the estabUshment of user control over their mobUe telephone. See Appendix A for all other Service Descriptions. Pre-Call and Pre-Answer: general points Currendy both the caUer and target experience is quite impoverished. At best the caUer can make suppositions about the avaUabiUty of the target, i.e. "It's 9:30am, they should be in the office by now". In this instance, there is no way for the caUer to determine the vaUdity of their assumptions without actuaUy placing the caU. SimUarly the target wiU at best be able to see the name and/or number of the person caUing. If the target can see the caUer ID, they may try to base their decision of whether or not to accept the caU on: possible reasons for the caU; the importance of the caUer; guessing the caU subject matter; their own convenience (amount of time they have to take the caU, where they are when they receive the caU) etc.. Other communication types have richer information: • face to face — visual cues indicate physical avaUabiUty of the individual and their readiness to communicate; • written communication - whUe the immediacy of the communication is removed and avaUabiUty less of an issue, the user has access to additional sources of information and, through its asynchronous nature, has time to think about the communication. Pre-caU and pre-answer offer respectively the caUer and the target the opportanity to have a far richer caH experience, enabUng them to make informed decisions when making and taking caUs. In some cases it may even alter the communication, replacing it with alternatives or stopping it altogether at that time. Pre-Call Current Stories: 1. Helen is about to leave the office and wants to caU Steve and to teU him that the plans for the evening have changed and to ask him what time he wUl be able to meet her. She selects Steve from her contact Ust and initiates the caU. Steve is in a meeting and has switched his mobUe to SUent mode. Helen is bumped to VoiceMaU and has to leave a message asking Steve to caU her when he has a minute. Pre-CaU means that when about to make a caU the caUer can see the Virtual Presence of the target. Steve could have put his mobUe into "Text Me" Mood and Helen would have seen this and contacted him appropriately, getting a response to her question without significant interruption to his meeting. Pre-CaH may include any of the foUowing types of information in addition to the fun, Avatar type visuaUsation discussed in previous section. AvaUabUity Information: • Mood Status of the target - i.e. 'Don't Disturb', 'Working', 'Out Partying', 'Commuting' etc. - these can encourage the caUer to either: caU immediately, caU later, send a text or voice message, not caU at aU etc. • Location Status — of varying granularity — i.e. 'London N17', 'Salisbury's — Clapham'. • Phone Status — i.e. 'Busy', 'AvaUable', 'No/poor network coverage', 'No battery' etc. • Target Messages - Working from home', 'Out on the town', 'Out of the office tiU 2 nd Feb 2001' etc. • PIM information - i.e. during the day data avaUable from the Calendar appUcation may indicate which meeting the target is currently in. In addition the caller may also see information from their own device pertaining to the caU. Supporting information: • Doodles — written by the caUer on a previous occasion regarding this caUer, i.e. 'Remember to ask x' etc. or taken dynamicaUy from the Calendar appUcation i.e. 'Daughter's birthday on 22 nd Feb'. (See Doodles Service Description). • View previous communications with the target (see Information Management Service Description). The caUer may also choose to actively provide the target with more information, for pre- answer i.e. entering a caU subject, or using flags to indicate whether the communication as 'Urgent', or 'Chat' etc. This expanded on in the next section. Pre-A swer Current Stories: 1. Sarah is in a meeting but has emailed Clive asking him to ring her with some information. She would be willing to accept the caH should it occur during the meeting. Sarah's mobUe rings during the meeting and she can see that it is CUve. She excuses herself from the meeting and accepts the caU. When she speaks to CUve it transpires that he hasn't received her query yet, he was simply caUing to see if she would be joining the rest of the team in the pub later. 2. Richard is in a meeting and his mobUe rings; the caUer ID indicates that it is his wife, Judy. She usuaUy rings him at the office during the day just for a quick chat, so he decides to bump her caU to VoiceMaU and get back to her when he has finished the meeting. Judy is upset as their son's school has just phoned asking them to come in to see them that evening; she is forced to leave him a message teUing him that she needs to talk to him a.s.a.p. Richard leaves the meeting an hour later and finds the distressed message caUs Judy back immediately. Pre-Answer means that when a caU comes in, the target can see the Virtual Presence of the caUer. By flagging a caU as urgent or simply aUowing the text message to come through Richard would have reaUsed the significance of the caU and probably chosen to take it, whereas in Sarah's case she may have chosen to 'bump' the caU to voicemaU as it was purely social. Pre-Answer may include any of the foUowing types of information in addition to the fun, Avatar type visuaUsation discussed in a previous section. • Name of the caUer. • Location of the caUer. • Mood Status of the caUer - this may in itself provide clues about the reason for the caU, i.e. 'Partying', 'Working'. The more that caUers customise their Virtual Presence the more meaningful the information to the caUer i.e. 'Out Clubbing', 'In Meeting' etc. • Specific subject/status information — this may have been specificaUy entered by the caUer to help the target or have selected it from a pre-canned Ust i.e. 'Urgent', 'Chat', Work' etc. It could also be gleaned from PIM/Smart data, i.e. if the caU is initiated from within a specific text message or from a calendar entry — the first few words could be visible to the target. The extent to which the caUer wiU bother to provide such information is dependent upon both die personaUty of the individual caUer but also the ease with which such information could be added. Supporting Information: • Doodles — written by the caUer on a previous occasion regarding this caUer — i.e. "daughters birthday", "remember to ask x" etc. (see Doodles). • View previous communications with the target (see Information Management). The target is not only in a better position to choose whether to accept the caU but to decide the way in which they accept the caU. For example, they may choose to screen the caU — hstening to the message being left on their VoiceMaU (See CaU Screening Service Description) and then decide whether to answer or not. They may choose to put the call on Hold initiaUy (See Hold Service Description) so that they can get into an appropriate location to answer the caU or so that they can view/Hsten to their own Doodle prior to taking the caU so that they are better prepared for the caU. They may simply answer or ignore the caU as currently. Convert To Text Currently when a caU is received the caUer can do one of three things: accept the caU; forward the caU to VoiceMaU or let the mobUe ring out and automaticaUy forward to VoiceMaU. Alternatively, if the mobUe is off or out of range then the caUer is automaticaUy forwarded to VoiceMaU. In aU but one case the communication ends even though there may be various reasons for not taking the caU, i.e. a noisy pub or in a work meeting. Convert To Text offers the target the abUity to manage the manner in which other people contact them. This may take the spontaneous/reactive route whereby during Pre-CaU the target indicates to the caUer that a text communication is preferable. Alternatively it may be that the target puts their mobUe into a 'Text only' Mood because they know they are going to be in a meeting or in a noisy pub etc. Hence, a caUer should then contact them via text or, if they go ahead despite the pre-caU message and place a voice caU, then the target can automaticaUy respond by inviting the caUer to participate in text communication. Current Stories: 1. BiU is in a club with his friends. His girlfriend, MicheUe, phoned him earUer to say that her train is running late and that she wUl be later than planned. She has agreed to caU him when she arrives at the station so that he knows when to look out for her. The club is typicaUy noisy and when MicheUe phones, BUI repeatedly has to shout that he can't hear what she is saying. In the end he has to run to the cloakroom, stick a finger in one ear and try again. 2. Tony is on the train home and his wife caUs him, as always, to determine what time to meet him at the station from work. On occasions people 'tut' at him or frown at the noise from his conversation and just occasionaUy he gets a bit of an earful from his wife about the fact that he is running late, and he then has to go into a lengthy explanation, something that he would rather not do in front of a crowded train. Regardless, he needs to teU her when he is leaving so that she can be at the station to pick him up. By being able to switch an incoming caU to text (Story 1) the target can take the caU in a way that suits them. Alternatively by automaticaUy putting the phone into a Mood whereby the caUer can see that they would prefer to be contacted by text, the communication can automaticaUy commence in the format suited to the target (Story 2). The addition of Location information as part of the Virtual Presence may even provide sufficient information to remove the need for the communication (Story 2). Call Screening Users already screen messages as they are being left on land Une answering machines. This service repUcates that functionaUty on the mobUe. The user is able to Usten in on a VoiceMaU as it is being left and can interrupt and take the caU or to stop Hstening and let the caUer continue to leave a VoiceMaU. In addition, poor and non-existent mobUe coverage is highly irritating for both the user when downloading material to the device or when Hstening to VoiceMaU. Text messages are sent to the mobUe when there is sufficient coverage: the same could be d e case for VoiceMaU enabling the user to Usten to messages even when coverage is intermittent. Current Stories: 1. George is sat in an important meeting when his mobUe vibrates. He can see that it is his son Thomas ringing. He is unsure about the importance of the caU but as he knows that Thomas should be on his way home from school he thinks that he ought to take the caU, just in case. George excuses himself from the meeting and takes the caU only to find that Thomas is caUing simply to teU hkn that he scored two goals during footbaU practise. George has to cut his chUd short and returns sheepishly to the meeting. IdeaUy George would be able to start Hstening to the caU, decide that it is better to speak to his chUd later when he can dedicate his full attention to the him. Hold and Mute As mobUes can be used practicaUy anywhere and people are increasingly unwilling to turn them off, it is not uncommon to hear a mobUe ringing in meetings or a restaurant or cinema etc. Occasions when it is inappropriate to some targets and certainly inappropriate for the people around them. Nor is it unusual for it to ring just at the wrong moment i.e. when 'working from home' just as the shop pubHc address pages a member of staff. Our research has shown that people frequently conceal the truth about where they reaUy are. Trying to take a caU when in an awkward situation frequently results in one of two activities "Hang on I'll caU you back in one minute" or the target continuing the caU and then proceeding to give the caUer a running commentary of their antics while trying to get to a convenient location to take the caU. Users want to be able to mute the audio of their handset whUe stiU being able to hear the caU, or place the caU on Hold initiaUy before they accept it so that they can get into a location convenient to start the caU. This could be easUy activated in the same way as Hold is currently activated once in a caU, i.e. using a prolonged press of the caU answer button or double cUcks of the caU answer button etc. A progression from putting a caU on Hold is changing the communication mechanism to one that is appropriate i.e. text (see Convert To Text Service Description). Current Stories: 1. Tom is on the train in a quiet carriage. He doesn't Hke taking caUs in pubHc areas Uke this, as he feels it is inconsiderate. On this occasion he forgot to turn his mobUe off and when it rings he is mortified and franticaUy hunts through his pockets to locate his mobUe and "bump" the caU. As he puUs it out of his pocket he can see that it is his wife caUing. He wants to take the caU but does not want to shout in the train carriage. He answers the caU so that she doesn't get bumped to VoiceMaU, but then has to start the conversation with "hang on I'm just having to move so I can talk to you" foUowed by several minutes of fumbUng and apologies to feUow passengers whUe he climbs over them to get to the end of the carriage. 2. Richard is supposed to be working at home, against a deadline. He has decided to take a break and go to Tesco's for some grocery shopping. Whilst in the shop, his phone rings and the caUer ID indicates that it is his boss. Richard reluctandy answers the phone and quickly answers his boss' questions, hoping that his boss wiU not hear the other shoppers in the background. Suddenly, a staff announcement is made and Richard has to cover the phone's microphone so that his boss does not hear the announcement. The caU ends, with Richard stiU wondering if his boss has figured out where Richard was. In both scenarios, a 'Hold and Mute' function would have been far preferable. Asynchronous Communication Voice Messaging Asynchronous behaviour is already a significant part of user's mobUe behaviour. The ease with which verbal messages can be created means that it is a nataral extension of the text messaging behaviour. The user should be able to create voice messages and send these directly to another person's VoiceMaU without the caUer being any more aware that this has happened than is currently the case with text messaging. It should also be possible to simply change data from one medium to another, (i.e. a voice note into an text message, a Doodle into an text message etc.). Data should be independent of the mechanism by which it is deHvered: Doodles, text or voice recordings can in the right situations form appropriate content for personal notes or the content of messages to others. The teen market view SMS as an ideal way of communicating with their friends. Communicating via text is for them a means of communicating in private (something which can otherwise be difficult both at home and school) and. voice SMS wUl enhance the speed with which they can do this. The need for privacy rather than speed is Ukely to be the determining factor when people are choosing between text or voice as the creation mechanism. Current Stories: 1. Susan is on her way out of the house when she remembers that she needs to caU her mother to and confirm dates for her visit. She is in a rush and knows that if she caUs it will be difficult to keep the caU short. On this occasion Susan decides not to make the caU. If she had been able to simply record a quick message to her mother, she would have removed the worry of forgetting to pass the information on and would be able to make a more leisurely caU at her convenience. 'Urban SociaUtes' particularly want to be able to offload information at a time convenient to them. At present they may leave making the caU until they know it is not Ukely to be answered or may simply avoid caUing aU together. Doodles It is not uncommon to make a caU and on ending the caU to remember something else that you wanted to mention. Depending on the person you have just caUed you may choose to caU them back and continue the conversation. However there are factors (such as time, status of the person being caUed, whether or not you wUl get the same person the next time you caU (i.e. a caU centre), personal confidence etc.) which determine whether or not it is a good idea to call again immediately. Similarly, when in the middle of a caU it is not uncommon to see people scribbHng notes or doodling on the back of a nearby envelope. These are activities that may or may not be connected to the caU itself. Some people claim to "think" better if they are doodUng aimlessly at the same time as talking. Information exchange is a common reason for a caU, and in some instances this may result in information that ideaUy they want to record in some way. As headsets, particularly Bluetooth headsets arrive, the need for the mobUe telephone to be held to the ear is removed. This frees up the interface of the screen for services that wiU enhance the caU experience. Doodles offer the user the abUity to associate data with a communication. At present users employ a number of techniques such as sending themselves text messages as reminders or sticking adhesive notes to the phone, such processes assume that i) the user remembers to look at text reminders and U) that the note is still stuck there. By associating the Doodle with the communication, i.e. the Contact, (ideaUy converting voice to text — unless operating with a headset) it would be possible to have reminders as part of Pre-CaU and Pre-Answer. It should also be possible to view and add to the Doodles while the caU is in progress, replacing the need for a notepad. Adhesive notes are often left on a coUeague's desk or are left around at home for other members of the famUy. They are either for the exclusive benefit of the other person (i.e. "your mother caUed at 3:30pm"), or for the use of both (i.e. "run out of milk and bread"). It should therefore be possible to send Doodles to other people (e.g. converting them to text messages). The difference to just sending a normal text message is that you can retain a copy and the appropriate "Unking" of that Doodle if so desired. It should also be possible to share a Doodle with other people. Doodles can be voice as weU as text and could ultimately be multimedia. Current Stories: 1. John has been trying to get through to his bank for a number of hours. He has a couple of queries for them. WhUe in a cafe for his lunch break he decides to try again. It is only after he has started the caU that he reaUses that the adhesive note he wrote to himself is back on his desk. The bank answers and he gets answers to two of his queries, he knows there was a third question but he can't remember for the Ufe of him what it is. After a few embarrassing moments of dithering he knows he is not going to remember the third point and he ends the caU knowing that he wiH have to caU the bank again later. 2. Matthew is in the pub with friends when he remembers he had Hitended phoning his sister Joanna to ask for the mobUe number of the restaurant that she had recommended he take his girlfriend to. Matthew is standing outside the pub entrance where it is quieter and makes the caU to Joanna. Joanna teUs hkn the mobUe number and Matthew repeats it hoping that he wiU be able to remember it until he gets back to the table where he can shred a beer mat and write the number on it for use later. 3. Tom and SaUy are having friends round to dinner in the evening. Whoever gets home first needs to pop round to the corner shop to pick up a few last minute ingredients. They leave an adhesive note at home so that whoever gets in first can take it back out with them. On his way home, Tom passes a convenience shop and thinks that he can remember all the ingredients. However, he doesn't know a) whether SaUy is home already and has therefore bought the ingredients already, b) that he has really remembered everything. Being able to capture information on the mobUe (either through voice or text - the former being preferable) enables users to transfer behaviours that they can easUy do currently on a landUne where paper and pens are Ukely to be at hand. In this instance however they can carry this data with them in the form of a Doodle without risk of loss (unless the mobUe itself is stolen too) and can even be associated with other information. In the last Story Tom could: use the Virtual Presence to determine SaUy's whereabouts, phone her to check whether she has bought the ingredients or more conveniently look at the shared Ust and see whether she has added a comment showing that she has bought everything akeady. Conventional appHcations such as Jotter and Notes provide the user with a mechanism for making notes in support of caU activities. However, this reUes on the user remembering that this note has been made and it requkes them navigating to it in a timely fashion for the caU. The advantage of Doodles is that the information can be created anywhere and associated within any relevant location. This may occur in one of two ways: 1. AutomaticaUy - creating a Doodle whUe in a contact detaU view could associate that with that particular contact such that should that contact be accessed in the future the Doodle wUl automaticaUy appear too. 2. User choice — the user may create the Doodle in one appUcation and choose to save it to another association, for example a Doodle created during a caU could automaticaUy associate it with that contact; alternatively the user could choose to save it in the to-do Ust or as part of a calendar entry as a reminder. In either case, estabUshing links ensures that the data is avaUable when it is needed. As in the case of Scenario 1, the caUer can associate the questions for the banker with the banks caU centre detaUs, he can add to these during the caU and retain a far more detailed record of the caU (and aH in the same location). Note: Data captured in this way may form part of another piece of device data, i.e. if as a result of the caU to the caU centre John has arranged an appointment with a bank manager, the notes made during the caU could become associated with the calendar entry also so that he has aU the information at his finger tips without having to hunt around for it. In addition a Doodle may simply be a link to data elsewhere on the device. To the user it appears as a Doodle but actaaUy it is content that has been flagged in another location i.e. the content of an emaU, or the section of a document etc. In the same way that a user can have layers of physical adhesive notes overlapping and Unking to each other in a physical manner, the same is the case for the electronic equivalent. Doodle can be linked to form a montage. In addition, the advent of the Bluetooth headset increasingly frees up the devices' interface for such activities such that the use of Doodles is viable not only prior to a caU but also during it: Doodles can be played as caUs come in if the user Pauses the caU prior to speaking to the caUer. WhUe Doodles have a key user benefit for the person creating them, there is also the flip side of the behaviour in that they are often given to other people. For example in Scenario 2, Doodle would have enabled Matthew to create an electronic record of the number as Joanna gave it to him. However they would also enable Joanna to help him out, i.e. by sending him a Doodle which not only contained the information but also an association information that it came from her. At which point Matthew would be able to choose to either leave the information associated with his sister or make it into a contact entry in it's own right. (Clearly she could sknply send him an SMS without the association. In some instances this is more appropriate though for example a coUeague sending a Doodle reminding the caUer to bring a document to the next meeting could be usefuUy associated with the actual meeting in question). The abUity to share Doodles requkes the hosting of the data in a central location rather on the device in order to prevent conflicts when data is being updated by either party. The underlying premise of a shared Doodle is that it is avaUable to both at aU times and that both parties can edit it: it is not necessary for either to own it. Play/Pause/Reply to VoiceMail Currentiy the extent to which users can interact with thek VoiceMaU is along the Unes of playing the messages and deleting them and setting preferences for how VoiceMaU notifies the user of messages waiting. IdeaUy VoiceMaU should enable the user to play individual messages, pause them and enable them to carry out tasks as a result of individual VoiceMaUs without having to Usten to the whole lot again. At present Hstening to a succession of VoiceMaUs requkes paper and pen, good coverage and patience. Appendix I - Other Service Descriptions Picture Messaging This relates to the abUity to send and receive (and create) visual messages - graphics or photographs. WhUe in the first instance simply being able to download pictures from the web onto the device and send these as images within a text message is sufficient, it is increasingly Ukely that users wiU want to take pictures and draw thek own. To then be able to make additions and alterations to existing images and photographs and to attach sound bites to them is essential. While there are clear work contexts for such a service, use in the social context is Ukely to be wide spread and given the often superficial nature of many text messages currently it is fak to assume that the use of pictures wUl foUow a similar Une and the abUity to annotate these wUl possibly enhance this. Evolvlcons The abiUty to present Moods in the vktual space lends itself to the development of appHcations which can buUd on the user's avatars and enable them to develop emotions as weU as sknply personal animations, sound and graphics. Being able to send emotions as weU as pictures, sounds etc. counteracts some of the sterUity of such static communications as text messages. In the first instance being able to annotate and doodle over images and photographs which are being sent to other people is fun, but being able to attach meaning to these of a non textual nature is even more aestheticaUy compelling. AppUcations which can reflect the relationships with contacts in the user's phone facUitate the development of not only emotional messages as described above but also in the extension of the Moods idea in that Pre-CaU and Pre-Answer data can grow as the relationship grows and can be customised on an individual level. People customise the Instant Messaging Presence dependent upon who can see that presence information. It is Ukely that people wiH also spend time customising thek Vktual Presence for key individuals. Information Management The mobUe akeady holds a significant amount of information. It contains aU the contact information and some devices enable the inclusion of additional textual information, including the text messages and email messages received to and sent from the mobUe telephone. As mobUe functionaUty increases the amount of information that can be made avaUable is potentiaUy huge. In certain ckcumstances this information can be of value to the user prior to or during a caU. The aU inclusive term Information Management may include: • Communications to and from the Contact. • Number of caUs and the cost of the caUs to the Contact. • Meeting entries associated with that Contact. • The last communication with a contact. • The next meeting scheduled with a contact. • The agenda for the last meeting with a specific group. So providing the user with the abUity to use and search this data can provide them with far more information in thek communications. The presentation of such information is system kiitiated in the case of Pre-CaU but user initiated during a caU. Ring Back If when a caU has been placed, and the caUer is akeady in another caU, the caller can initiate Ring Back which offers the abUity to specify that when the Une becomes free a caU between the two parties should be automaticaUy initiated. This replicates functionaUty akeady avaUable on land Unes. If via Pre-CaU the caUer can see that the caUer is currently on the mobUe, the caUer can initiate Ring Back without needing to fkst place the caU. Appendix II Presence: architecture aspects The reaUsation of a Presence/Voice++ system wiU requke an architecture for instant messaging and presence awareness/notification which includes: a concept of identity, authentication, access control, encryption, message integrity and shared content. Identity Clearly, identity is essential: individuals wUl use several devices of different types, and capabUities, requking an effective and efficient addressing system to handle and simpHfy the multitude of emaU addresses, phone numbers and www-addresses for individuals, groups and organisations. This may also necessitate some form of classification of the basic modes of communication to help define the basic requkements for appHcations, devices and service providers. Importantly, individuals may wish to assume several different 'Identities', for communicating within different contexts. Actor J Personae • An Actor has 1 to n Personae through which they communicate with other Actors, i.e. communication is Persona-to-Persona based rather than Actor-to Actor based. • The Actor 'owns' the data/information/ files in its Personal Universe but provides restricted views/access to it through thek set of Personae. • In addition, each Persona has values for a set of Persona-based attributes associated with it (e.g. Nickname, font for chatting, icon for Avatar, etc. as weU as a Persona Personal FUe containing thek 'history' - schools, hobbies, clubs, likes, disUkes etc.) - this must be extensible so that communities of Personae may be set up, each containing thek own distinct community-based information — e.g. a multi-user game which requkes Persona to have certain attribute/ value pairings for such things as Strength, Λgilit , Life, Bullets, etc. • Each Persona is uniquely identifiable such that it can act in end to end communications. This should not be device specific as the ID provides a means of communicating with the Persona not the method. Initialyl users will be given choice of communication methods (phone, email (work! home) etc.) and will make the appropriate choice given the set of presence and availability information. Later systems may route a message (with appropriate translations — voice/ 'text text/ voice etc) to the appropriate device depending on the availability policies set up by an individual. • It is the Personae that appear in Dkectory LookUp services. • Each Persona has its own Presence Information. • One persona is the Master Persona that is the true representation of the Actor. This may be an authenticated/ signed persona. • A Persona may be anonymous. Presence In its basic form Presence enables people to communicate with each other in the most appropriate and timely fashion. It should be possible for this presence information to be refined with levels of avaUabUity (e.g. 'away from device but back soon', 'do not disturb', etc.). Some of these refinements should be understood by the software so that they behave in appropriate ways whUe others may simply be displayed to other cUents in a human readable form for them to decide how to respond. An Actor should not need to maintain presence information at aU times on aU known contacts. Instead they should maintain a 'buddy Ust' with thek favourite contacts. Presence information can be maintained by 'subscription' whereby changes are pushed to interested parties or returned when specificaUy requested (by a 'watcher' or 'poUer'). An Actor may only want subscriptions to be possible to selected other Actors/Personae. Presence information comprises dynamic information such as location and avaUabUity, etc., which typicaUy has expkation data that needs to be enforced. InitiaUy, at least, avaUabUity wUl be inferred from the recipient's pubUshed mood and the status of the device. AvaUabUity • A property of a Persona denoting its abUity and willingness to share information about itself or to communicate with another Persona based on factors such as: • the type of communication requested; • device avaUabUity and status (out of coverage, downloading data, etc.) • the identity of the caUing Persona; • the mood of the recipient; • the preferences and poUcies that are associated with the recipient. Mood • A setting which aUows the user to provide an indication of thek state of mind. This is Ukely to provide not only thek state of mind but an indication of thek avaUabUity and a preference for how they want to be contacted. I.e. If 'Angry' and 'Busy' the user may have specified that this means they are only avaUable for chatting in text form. Location • GPS (absolute and translated). • Bluetooth Pods in offices etc. • Text (e.g. 'Down the White Horse'). Architecture • CHent/Server. • An Instant Messaging and Presence (IMP) Server holds master copies of Presence information and other Personal Data (Personal Universe). • Personal data could include such things as: MP3 files; photos; credit card detaUs; DoB and other auto from fill stuff; medical records; Agenda; PubHc PGP key, etc. i.e. file, record and transaction based shared content. • The server Ustens for cHent connections and communicates dkectly with cHents and other servers. • The server also handles: data storage, user authentication, directory lookups (e.g. LDAP) and Rosters, etc. • The cUent communicates with the IMP server, parses and interprets weU-formed XML packets and understands message data types. • Each Actor and thek set of Personae is associated with a single server which receives information for them and from them. • CHents make a single connection to thek server over which aU communication exists. • Distributed communication happens cUent->server [->server] ->cUent. • The servers transfer messages and presence information between themselves and, with the appropriate interoperabiUty standards in place (e.g. SIMPLE), with other external IM and presence systems too. • When a Persona's Presence or other Personal Data changes (either expHcitly by the Persona, or impHcitly by, for example, a timeout, the IMP server is updated. • For Presence information this may be very simple in the fkst instance, aided by a set of profiles for ease of use, or an enumerated set for programmatic processing plus a text field for additional information. • Individuals hold cached copies of other's Presence information (and other information - probably more static in nature). This is just for Buddies but may wish to view available public presence information on anyone: Anonymous Presence Request. • When a buddy's presence information or Personal Data changes, and if they are permitted to access the particular data that has changed, and if they have subscribed to that data, they are informed. The changes wUl either be pushed or puUed depending on subscription model. Pushed changes wiU be immediate whereas puUed changes will be retrieved when the server is next poUed. Could force a push. • The Presence Data could be time-stamped with when the information was last updated. Data Format/Protocols • CHent/Server protocol (preferably an open XML-based standard). Used for cHent-server, server-cUent and server-server communication (session initiation, modification and termination). • Server-to-server protocol — could be proprietary between homogenous systems but wiU probably be SIP/SIMPLE for interoperabUity between heterogeneous systems. • Data representation protocol: a fundamental requkement of the architecture is that it must be extensible. As such, an open XML-based standard protocol should be used for packaging/ transporting data (IM, presence data and personal information). The protocol should use XML Namespaces to encapsulate other kinds of data sent, aUowing any cUent, server, transport, or any component of the architecture to build custom appHcations by including thek own XML data within thek namespace. Could be SOAP. Messaging • Messaging is essentiaUy the sending of some data from one Persona to another. The data is not restricted to text, but may be any weU-formed data that can be recognised by cHents including text, voice, multimedia, Presence Information, etc. • Common standards for these data types coupled with a common standard for thek transfer (described above) will greatly ease the development, roU-out and adoption of data services and appHcations that build upon this architecture. • One appUcation of this is Instant Messaging, which wiU be enhanced by both the richer Presence Information avaUable and the support for other more complex data types over and above the simple text of current systems. • Not just person to person messaging: appUcation to appHcation messaging wUl also be possible, possibly using SOAP. • The inherent extensibiUty of the architecture will aUow new data formats to be supported. Security and Privacy Privacy • White Pages should be an opt-in subscription model, aUowing the user the choice of whether or not to pubHsh thek information. • The use of server and chent-side filters would give users the abiUty to deny communications by user, domain, message type, or content, etc. Authentication: • Simple username/password system. • Digest authentication. • Digital signatures. • PKI Encryption • PGP or S/MIME ...authentication is a must but encryption, although provided, should be optional— user does not have to use the feature. Secure Connections • SSL (Secure Socket Layer) can be used to create a secure connection between the cHent and the IMP Server to ensure that usernames, passwords and messages cannot be intercepted. • IPSec Transports • Protocols should be transport-independent: HTTP, WAP, SMS/MMS, etc. Namespace & Addressing • GlobaUy Unique ID • Or Domain-based: node@domain.com. Example: MyPersona( ) indkect.com Directories and User Management • Along with a flexible messaging and presence system, an XML-based dkectory should be provided. • As to account management, the server by default wiU aUow every user to have fuU control over the creation of and management of thek account. This includes passwords, and aU presence, personal data and messaging aspects. Server administrators have fuU control over the rights aUotted to each account, and can remove or limit those at any time. PreAnswer. Using the architecture described above current GSM Systems could support some form of Pre Answer: Post 1. Before caUing, a caUer posts CaUer Information onto the server (using, for example, SMS); 2. The caUer then makes the caU. Before it rings, the CaUee's phone makes a data caU to the server and requests 'CaU Information' for the CaUing 'Persona'. 3. This is then displayed, and the phone rings. However, as weU as being burdensome and particularly prone to latency problems, it has security impUcations as weU - how to restrict only the CaUee from accessing the CaU information. Supply Another method would be to simply 'handshake' using messages (SMS, EMS, or MMS) to carry 'Pre Answer' information payload (based on a standard for such data). 1. To initiate a caU, a caUer sends the CaUee a 'Pre Answer' message that the CaUee's device recognises. 2. On reciept, the CaUee's device alerts the CaUee and displays the 'Pre Answer' information. The CaUee can chose to ignore, accept or return a message. 3. If the CaUee wishes to accept, then a return 'Accept' message is returned which the CaUer's device recognises and promptly initiates a phone caU to the CaUee. This is also burdensome and prone to latency problems, though not as stark as in the previous solution. However, networks are moving towards whoUy IP-based infrastructures and the adoption of the SIMPLE (SIP for Instant Messaging and Presence Leveraging Extensions) protocol as the standard interoperabUity protocol and the widespread support it enjoys (from, for example, AOL and Microsoft) may accelerate the process. This will provide an ideal infrastructure for roUing out such features as Pre Answer, the abUity to move seamlessly from one type of session to another (data to voice for example), estabHshing conference caUs, and so on. In such an envkonment, and assuming SIP/SIMPLE and the architecture described above: 1. The caUer would estabUsh a communications session with the desked party. Initiating a session simply requkes determining where on the network an invited party is at a particular moment (using the poUcies/mechanisms described above). Once the invited party is located, SIP deUvers a description of the session (which among other data, includes the type of session desired, in this case 'Voice', and the 'Pre Answer' information) to which the person is being invited. The most common protocol used to describe sessions is the SDP (Session Description Protocol), described in RFC2327. 2. Once the person is located and the session description is deUvered, SIP is used to convey the response to the session invitation (accept/reject). If accepted, the (voice) session becomes active. 3. SIP can be used to modify the session (e.g. switch to video, or data). 4. FinaUy, SIP can be used to terminate the session.

Claims: Claims 1. A method of communicating user related information using a wkeless information device in which a caUer using a fkst wireless information device enters into the device information of potential relevance to a caU recipient, the information being of a kind which varies; the method comprising the step of transferring that information to a second wkeless information device controlled by the call recipient, such that the call recipient is automaticaUy provided with the information prior to accepting or answering a voice caU from the caUer. 2. The method of Claim 1 in which the fkst device communicates the information dkectly to the second wkeless information device. 3. The method of Claim 1 or 2 in which die fkst device posts the information onto a database which is readable by any person to whom the fkst person has given appropriate access rights. 4. The method of Claim 3 in which the database is hosted on a web server. 5. The method of any preceding Claim which the information is sent as data prior to a voice channel being opened. 6. The method of Claim 5 in which the information is sent as SMS, Smart Message or a data packet data prior to the voice channel being opened. 7. The method of any preceding claim in which the information includes one or more of the foUowing: (a) a mood; (b) a current activity; (c) a part or whole of a schedule of meetings or events; (d) information about the subject of an intended voice caU; (e) information about the urgency of an intended voce caU; (f) information about the Ukely duration of a telephone caU; (e) personal information; (g) location information; (h) graphics or icons; (i) commercial inducements to answer a caU. 8. The method of Claim 1 in which the information is a customisable personal avatar, graphicaUy representing a user. 9. The method of any preceding claim in which an alert is sent to a caUer when the information describing the situation of a caU recipient alters in a way defined by the caUer. 10. The method of any preceding claim in which the caU recipient sets a fkst device so that it does not receive voice caUs and a caUer with override rights defined by the caU recipient can override that setting so that the first device does receive a voice caU from that caUer. 11. The method of any preceding claim in which the caU recipient can elect not to proceed to accept a voice caU and is automaticaUy provided with an option to exchange data messages with the caUer. 12. A wkeless information device controUed by a caUing party and programmed (i) to aUow information to be entered into it, the information being of relevance to a caU recipient with whom the caUing party wishes to communicate, and being of a kind which varies, and (U) to transfer that information so that it can be read by a second wkeless information device controUed by the caU recipient; whereby the caU recipient using the second device is automaticaUy provided with the information prior to answering or accepting a voice caU from the caUing party. 13. The wkeless information device of Claim 12 when used in a method as defined in any of Claims 1 — 11. 14. Software for a wkeless information device which, when running on the device enables the device to operate as a wkeless information device as claimed in Claim 12 or 13. 15. A method of generating revenues relating to the use of an appHcation on a wkeless information device, in which the wkeless information device is as claimed in Claim 12 or 13. 16.
