Abstract:
An exemplary embodiment builds on the idea of presence and SIP messaging in conjunction with a profile comprising, for example, a lookup table and a rules module, to assist with one or more of reminders, actions, endpoint maintenance, availability, endpoint capabilities and session management. One exemplary embodiment provides a message-based notification system. SIP allows a user to associate themselves with a number of different User Agents (UAs). This means that a user may have a presence on more than one UA at any given time, e.g., soft phone, PDA, and workstation. One exemplary embodiment utilizes this fact in connection with monitoring and determining if a message is a trigger-type message to provide more timely and relevant notifications to users.

Description:
FIELD OF THE INVENTION 
     An exemplary embodiment of the present invention is directed toward communication technologies. More specifically, an exemplary embodiment is directed toward detecting one or more SIP messages, and taking an action at least based thereon. 
     BACKGROUND 
     “Presence” is well known in the telecommunications industry. Presence and presence information relate to a person having multiple devices with multiple communication paths and a user&#39;s preference or preferred device of availability. “Presence information” typically refers to any information associated with a network node and/or endpoint device, such as a communications device, that is in turn typically associated with a person or entity. Examples of presence information include registration information under the Session Initiation Protocol (SIP), information regarding the accessibility of the endpoint device, the endpoint(s) telephone number or address, the recency of use of the endpoint device by the person, recency of authentication by the person to a network component, and the preferences of the user, such as contact mode preferences or profiles, such as the communication device to be contacted for specific types of contacts or under specific actual scenarios or presence contacts, contact time preferences, impermissible contact types and/or subjects, such as the subjects about which the person does not wish to be contacted, parties who must not be contacted, i.e., a do not call if you are not calling on behalf of a specific person or entity, and parties who can contact at any time, e.g., “I will accept a call from the head of the company regardless of what I am doing.” 
     Typically, the presence information is communicated and updated via one or more SIP-based messages exchanged, for example, between one or more endpoints and/or one or more application servers. 
     Presence information can be user configurable, i.e., the user can configure the number and type of communication and message devices (endpoints) with which they can be contacted and define profiles that govern the communication and message options presented to the incoming contact or in specified factual situations or sets of facts. By identifying a pre-defined set of facts, a profile can be accessed and followed to direct the contact to the user/preferred device. 
     SUMMARY 
     Session Initiation Protocol is a signaling protocol that can be used for establishing sessions in an IP network. The session can be a simple two-way telephone call, or, for example, could be a multi-party multi-media conference session. SIP protocols are well known and allow the ability to establish and break-down sessions in a host of different service options such as voice-enriched, e-commerce, web page click-to-dial, instant messaging, IP Centrex services, and the like. SIP messaging is also used in conjunction with presence monitoring to provide a telecommunications architecture with endpoint status. As will be apparent from the discussion of the exemplary embodiments of the invention described herein, the systems and methods of this invention can use SIP protocols and associated SIP servers, such as presence servers and databases(s), to implement the functionality, actions and messaging described herein. 
     SIP messaging provides the ability to prepare and provide notifications to people based on their location. However, the rules used to trigger notifications are typically based on a user&#39;s physical location (i.e., GPS based notification systems, RFID based access control systems, etc.) These triggering events may not adequately and timely provide a notification to a user because they are based on spatial relationships, which may be ambiguously defined and therefore not as useful. 
     An exemplary embodiment of the present invention builds on the idea of presence and SIP messaging in conjunction with a profile comprising, for example, a lookup table and a rules module, to assist with one or more of reminders, actions, endpoint maintenance, availability, endpoint capabilities and session management. 
     One exemplary embodiment of the present invention provides a message-based notification system. SIP allows a user to associate themselves with a number of different User Agents (UAs). This means that a user may have a presence on more than one UA at any given time, e.g., soft phone, PDA, and workstation. One exemplary embodiment of this invention utilizes this fact in connection with a reminder system to provide more timely and relevant notifications to users. Consider the following exemplary scenarios. 
     Suppose that a user is logging out of his/her IM application on the computer, the messaging used to complete the logout procedure may be dual-functioned to initiate the generation of a reminder message or at least invoke a set of reminder message rules. Thus, a user may have a reminder setup for when they leave the office. A reminder generated in response to seeing that the user is logging out of the IM application will likely get to the user sooner than a reminder generated in response to seeing that the user is physically leaving his/her office. Therefore, if the reminder pertained to getting something from the office, less time is wasted because the user gets the reminder more quickly than if their location was used as the triggering event. 
     Suppose that a user is checking their voicemail. That user may have generated a reminder to call back a client to follow up on an order. When the person logs into their voicemail account the messaging used to log the user in may be utilized to retrieve/generate the call-back reminder. Then, when the user attempts to log out from the voice mail system, the reminder may be transmitted to the user either at the phone they are on or some other UA as determined by the user&#39;s preferences. This allows the reminder to be sent to the user when they are (1) not busy on the phone but (2) near the phone and in the mode of making calls. This is more convenient than providing a reminder to call someone back as they are leaving or entering the office. The reminder may also be generated and sent to the user at another UA (e.g., their cell phone) if the call is going to be a personal call rather than a business call or a long-distance call rather than a local call. The message type and origination/destination of the message may be used to determine which rule set is invoked 
     Extensions to the invention may include utilizing GPS information to further identify the type of message that should be provided to a user. This may allow the system to couple location information with the message-based triggering to further refine which and how the message is provided to the user, as well as define the content of the message. 
     For example, in a commercial repair service environment, SIP messages, e.g., presence information, GPS information and schedule information (such as which repairs are scheduled for a given day and what parts are need for each repair) for a given time period can be utilized to provide more timely and relevant notifications/reminders to users. These notification/reminders could be dynamically assembled based on information aggregated from one or more schedules, email, calendars, tasks, contacts, GPS coordinates associated with the scheduled events and expert system input. 
     Further extensions to the invention include allowing third-parties to generate notifications/reminders for other users. As one example, when two parties are on a phone call, one of the parties may create a reminder for the other party (e.g., an action item identified during the phone call). That reminder may be created and queued for the counterparty. Transmission of the SIP BYE message from one device to the other device may trigger the transmission of the action item reminder. Permissions and privileges may also be used to identify who can and who cannot create reminders for other persons. 
     Information such as the permissions and privileges, as well as parameters regarding certain action items can be stored in one or more profiles associated with one or more of an endpoint and a user. An exemplary profile can be developed by monitoring communications with a person and recording information such as what did the user do on receipt of a certain type of information, how a user establishes their reminders, how a user prefers to be contacted, e.g., mobile phone, work phone, home phone, etc., and at what times. 
     Presence systems can also be used in conjunction with the present invention and can assist in determining availability e.g., if Windows® Outlook indicates a person is not online, they are most likely not at their desk and will not be able to see a task reminder displayed on the desktop. An exemplary feature of this invention could recognize a message between the user&#39;s desk phone and an application server to call-forward communications to a PDA. Based on this message, the system could automatically forward the task reminder to the call forwarded device. 
     “Call”, “communication” or “contact” as used herein is indicative of a connection or request for connection between two or more communication devices or endpoints. As will be appreciated, contacts could be of various types and forms, such as wireline or wireless, circuit and packet-switched voice contacts, e-mail, instant messaging, faxes, video messages, paging signals, VoIP sessions, chat sessions, video conferences, multimedia communications, multimedia multi-party messages, cross-media messages, multimedia conference sessions, or in general any type or form of communication over any type of media. Moreover, availability intelligence can be combined with presence and predictive capabilities, where availability intelligence refers to processed, e.g., compiled, cross-referenced and/or filtered, presence information or meta-information. Furthermore, as is known, policy rules associated with a callee&#39;s name space can be mapped against one or more of the presence information, intelligence information, or the like, and utilized in conjunction with the present invention to at least assist with determining an appropriate action to take (if any). 
     An exemplary aspect of the invention is thus related to establishing communications between parties. 
     More specifically, an exemplary aspect of the invention relates to monitoring messages used to establish, maintain and break-down communications sessions.

     Additional aspects of the invention relate to identifying and rerouting and/or replicating certain types of messages. 
     Additional exemplary aspects of the invention relate to using an xml API or command module to assist with the performing of an action. 
     Additional aspects of the invention are suited to implementation in a Back-to-Back User Agent (B2BUA) where the B2BUA acts as a User Agent server on one side and as a User Agent client on the other (back-to-back) side. The B2BUA is thus particularly well suited to receive session messages. The basic implementation of a B2BUA is defined in RFC 3261 and can provide call management, network interworking, hiding of network internals (private addresses, network topology, etc.) and codec translation between two call legs. Because it maintains call state for all SIP calls it handles, message monitoring, detection and action initiation can be performed by a single endpoint. 
     These and other features and advantages of this invention are described in, or are apparent from, the following detailed description of the exemplary embodiments. The embodiments and configurations herein are neither complete nor exhaustive. As will be appreciated, other embodiments of the invention are possible utilizing, alone or in combination, one or more of the features set forth above or described in detail below. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       Exemplary embodiments of the invention will be described in detail, with reference to the following figures wherein: 
         FIG. 1  illustrates an exemplary communication system according to this invention; 
         FIG. 2  illustrates exemplary componentry that can be associated with one or more endpoints according to this invention; and

     DETAILED DESCRIPTION 
     Exemplary embodiments of this invention will be described in relation to communication, communication detection and action determination. However, it should be appreciated that in general, the systems and methods of this invention will work well for any type of communication in any communication environment using any communication protocol(s). 
     The exemplary systems and methods of this invention will be described in relation to telecommunications systems, and associated telecommunications hardware, endpoints, software and/or communication channels. However, to avoid unnecessarily obscuring the present invention, the following description omits well-known structures, network components and devices that may be shown in block diagram form, are well known, or are otherwise summarized. 
     For purposes of explanation, numerous details are set for the in order to provide a thorough understanding of the present invention. It should be appreciated however, that the present invention may be practiced in a variety of ways beyond the specific details set forth herein. 
     Furthermore, while the exemplary embodiments illustrated herein show the various components of the system collocated, it is to be appreciated that the various components of the system can be located at distant portions of a distributed network, such as a telecommunications network and/or the Internet or within a dedicated secure, unsecured and/or encrypted system. Thus, it should be appreciated that the components of the system can be combined into one or more devices, such as a PBX, application server, or communications device, associated with an ACD (Automatic Call Distribution) system, or the like, or collocated on a particular node of a distributed network, such as an analog and/or digital telecommunications network, a circuit-switched network and/or a packet-switched network. As will be appreciated from the following description, and for reasons of computational efficiency, the components of the system can be arranged at any location within a distributed network without affecting the operation of the system. For example, the various components can be located within a PBX, at one or more users&#39; premise, or some combination thereof. Similarly, one or more functional portions of the system could be distributed between a telecommunications device(s) and an associated computing device. 
     Additionally, the communications between the endpoints can at least be from one or more of a telephone, cell phone, instant messaging system, laptop, personal computer, personal digital assistant, text messaging system, e-mail, fax, IP phone, application server(s), or in general any known or later developed system or means for communication. 
     Session Initiation Protocol or SIP, which is a simple signaling/application layer protocol for data network multimedia conferencing and telephony, can also be used with the present invention to provide, for example, a means for determining a users actions and assist with providing presence awareness in a communication network. Although other protocols are equally supportive of presence concepts, SIP provides an illustrative basis for the present invention. 
     It should also be appreciated that various links, including any communications channels and the various links 5, connecting the elements, can be wired or wireless links, or any combination thereof, or any other well-known or later developed element(s) that is capable of supplying and/or communicating data to and from the connected elements. The term module as used herein can refer to any known or later developed hardware, software, firmware, fuzzy logic, expert system, neural network or combination thereof that is capable of performing the functionality associated with that element. The terms determine, calculate and compute and variations thereof, as used herein are interchangeable and include any type of methodology, process, mathematical operation or technique. Furthermore, it is to be noted that the term “a” or “an” entity refers to one or more of that entity. As such, the terms “a” or “an”, “one or more” and “at least one” can be used interchangeably herein. It is also to be noted that the terms “comprising”, “including” and “having” can be used interchangeably. 
     Also, while the flowcharts have been discussed and illustrated in relation to a particular sequence of events, it should be appreciated that changes, additions, and omissions to this sequence can occur without materially affecting the operation of the invention. 
     As will be appreciated, the communication system can also comprise other well known components which will not be described herein in detail. For example, the communication system can further include one or more telephony switches/media servers that can be of any architecture for directing communications to one or more communications devices. The network(s) (not shown) can typically include proxies, registers, switches and routers that are well known. Incoming contacts or communications can be from communication devices, e.g., endpoints, associated with a caller/callee or can be any device or devices suitable for communication over the network to which they are connected. For example, the communication devices can be any wired or wireless device such as an IP hard phone, IP soft phone, personal digital assistant, Blackberry®, Treo®, personal computer or PC, laptop, mobile phone, traditional PSTN phones, cellular phones, or any combination thereof. 
     The exemplary communications system  1  includes one or more SIP endpoints  20 , one or more application servers  10 , and optionally a proxy server  30 , all connected by one more links and/or networks (not shown). Communications sessions between the one or more endpoints  20  and application servers  10  are established, maintained, and terminated through the use of various SIP messages between the appropriate devices. Typical SIP messages between the devices include REGISTER, INVITE, ACK, CANCEL, BYE and OPTIONS. 
     The SIP messages are either requests from a server or client or responses to a request. The above-mentioned six types of requests are broken down as follows. INVITE indicates a user or service is being invited to participate in a call session. ACK confirms that the client has received a final response to an invite request. BYE terminates a call and can be sent by either the caller or the callee. CANCEL cancels any pending searches but does not terminate a call that is already been accepted. OPTIONS allows the querying of the capabilities of one or more servers and REGISTER registers the address listed in the “To:” header field with a SIP server. 
     In accordance with an exemplary embodiment of this invention, it is these SIP messages that are exchanged between the various communication endpoints that trigger a corresponding action. More specifically, and in relation to  FIG. 2 , illustrated is an exemplary SIP Message Action Module (SMAM)  100  according to an exemplary embodiment of this invention. In particular, the SMAM  100  includes a message monitoring, filter and forwarding module  110 , a message replication module  120 , a back-to-back user agent module  130 , XML command module  140 , action module  150 , message analysis module  160  and controller/memory  170 . The message analysis module  160  further includes an artificial intelligence module  162 , on or more lookup tables  164 , and a rules module  166 . 
     In general, the various components and modules illustrated in  FIG. 2  cooperate to detects certain types of messages between certain endpoints, and then, if appropriate, decide and take an action based on one or more rules, information, lookup table information, artificial intelligence and an expert system. More specifically, the message monitoring, filter and forwarding module  110  monitors one or more messages to and from an endpoint. Each message can be analyzed and correlated to, for example, information in the look up table  164 , to determine if that message has an associated action. Messages, for which no associated action is identified, can be ignored. 
     There are a number of options for when a message that has an associated action is detected. In accordance with one exemplary embodiment, the actionable or trigger-type message can be forwarded to a specific destination, such as an application server. Alternatively, or in addition, and in cooperation with the message replication module  120 , the trigger-type message can be duplicated and forwarded to a specific destination, such as an application server. 
     For example, while the SMAM  100  is illustrated as including all the various modules to implement the basic functionality of this invention, it should be appreciated that the various modules could be processor intensive and therefore offloaded from a simple endpoint to a more processor-centric device, such as an application server. Therefore, according to one exemplary embodiment of the invention, the message monitoring, filter and forwarding module  110  could be located on a “lite” endpoint along with the message replication module  120 , which then forwards a trigger-type message to a message analysis module  160  located in, for example, an application server  10 . An endpoint, such as a Blackberry®, may have sufficient processing and memory capabilities to house virtually all of the functionality provided in the SMAM  100 . In this case, the message replication may not be needed and the message monitoring, filter and forwarding module  110  can cooperate directly with one or more of the message analysis module  160  and action module  150  located on the device itself. 
     The back-to-back user agent module  130  is illustrated as an optional agent and is particularly well suited to cooperate with the message monitoring, filter and forwarding module  110  since it handles communications as both a client and server. 
     In operation, the message monitoring, filter and forwarding module  110  monitors messages between one or more endpoints. The monitoring can be a single message or a sequence of messages, such as the sequence of messages that are used to establish, maintain and break-down a SIP-based communication session. As discussed, the messages are filtered such that only messages identified as being a triggering-type message are forwarded to the message analysis module  160  to determine if there is an action associated with that message, or a particular sequence or combination of messages. Assuming the message(s) is of a type that is a triggering-type message, the message analysis module  160  receives the message and analyzes the message including one or more of the message type, source information, destination information, and optionally one or more of presence information, and user(s) profile information associated with any one or more of the endpoints and users associated therewith. This analysis can be based on one or more of an artificial intelligence analysis of the message in cooperation with the artificial intelligence module  162 , a lookup table approach  164  and a rule based approach in conjunction with the rules module  166 . The analysis module  160  can also cooperate with the controller/memory  170  and access a user profile (not shown) to assist in determining whether an action is associated with the trigger-type message. Information that can also be included to assist with the analysis by the message analysis module  160  includes the user location, SIP URI, the availability of the user, the availability of other users in the communication session, session setup information, capabilities of the one or more endpoint devices associated with this session, session management information, and in general any information associated with a communications session. 
     In addition to the above, the message analysis module  160  can also look to further information such as calendar information, e-mail client information, task information, schedule information, and in general, any information available to assist with determining what is the appropriate action to take based on the trigger-type message. 
     As an example, the artificial intelligence module  162 , upon receipt of a trigger-type message first analyzes the source and destination information associated with the message. The artificial intelligence module  162  can also dip into associated applications and determine related actionable items based, for example, on a correlation between one or more of the source and destination information to that actionable item. For example, if there is a task in a users e-mail application associated with the destination the user called, (for example, the correlation can be made between the e-mail address and the SIP URI) this task could be displayed to the calling party to act, for example, as a reminder that there is an open actionable item. The artificial intelligence module  162  can also look at, for example, historical information associated with the parties in the communication session to determine if the user accepted or rejected the proposed actionable item. As discussed hereinafter, a prompt can be presented to the user providing them with information regarding the type of action(s) that the message analysis module  160  determined was appropriate, and whether or not the user wants to proceed with that action. 
     In accordance with an alternative operation of the message analysis module  160 , the message can be compared to a lookup table  164  to see if there is a corresponding action. For example, if a user sends a BYE message to log-out of their computer and office voicemail, the lookup table can indicate that all messages should be forwarded to a mobile messaging device upon receipt of this type of message. As yet another example, if a user sends a redirect message to, for example, their application server, the lookup table  164  can compare the destination of the redirect to, for example, information of the users profile, and recognize that the redirected destination device is not HTML enabled, and forward all communication(s) to the device in an SMS protocol. 
     As yet another example, the user editable rules module  166  can include one or more pre-defined or user-created rules that corresponded to certain trigger-type messages. These rules can be of a high level, for example, directed toward a specific message type alone, or can be more granular in nature, such as they only apply to a specific message type with a specific sender, recipient and/or SIP URI or a specific message header(s) or information contained within a particular message header. Additional details of known SIP headers are described in Sofia-SIP 1.12.9devel1, a publication of Nokia, the entire contents of which are hereby incorporated herein by reference and are also available at http://sofia-sip.sourceforge.net/refdocs/sip/group_sip_headers.html. 
     Once a determination has been made that an action is appropriate based on the trigger-type message, the message analysis module  160  cooperates with one or more of the action module  150  and controller/memory  170  to perform or initiate the action. As discussed, these actions can includes reminders, communication rerouting, prompting, updating presence information, or in general any action item. Optionally, and instead of the action being automatically performed, once it is determined by the message analysis module  160  that a message is appropriate, the action module  150  can query the user and present to them the determined action and ask for confirmation as to whether this action should be performed. This query can be provided graphically, audibly or via a message, such as an SMS message to the user. For example, based on the endpoint associated with the user at the particular time an action is determined to be appropriate, the query can be customized based on the specific capabilities of that user&#39;s endpoint. In addition, an interactive voice response service (not shown) could also be used to interact with the user to determine if the action should be performed, and further provide the ability for the user to customize the action based on the selection of certain parameters. Additionally, whether the action should be performed automatically or not could be stored in a profile or associated with the rule or lookup table. 
     The action module  150  can also cooperate with the XML command module  140  send an XML API as well suited for use with this invention. 
     In addition to reviewing SIP messages, the analysis module could optionally dip into one or more of communication history, profile information, history information, and the like, as well as into any other source(s) of information, and use this information to assist with action determination. In general, information from any source can be assembled and used in conjunction with the message analysis module to assist in determining an action. The availability of this information could optionally be user selectable, as well as governed by one or more rules, privacy filters and/or other individual filtering criteria. 
     Table 1 below illustrates numerous types of trigger-type messages and exemplary associated actions. This table should not be considered as complete nor exhausted, and merely provides a handful of very simple applications of exemplary embodiments of the present invention.

       FIG. 3  outlines an exemplary method of SIP presence based notifications according to this invention. In particular, control begins in step S 100  and continues to step S 110 . In step S 110 , one or more trigger-type message are detected. Next, in step S 120 , and if the message is a type that should be forwarded to the analysis module, the message is forwarded thereto. Then, in step S 130 , the message is analyzed. The analysis of the message can include one or more of the message type, source information, destination information, and in general, any information related to the message. The analysis of the message can be in conjunction with one or more of an artificial intelligence based analysis (S 140 ), a lookup table-based analysis (S 142 ) and a rules based analysis (S 144 ). Control then continues to step S 150 . 
     In step S 150 , a determination is made whether an action should be performed. If an action should be performed, control continues to step S 160 . In step S 160 , the action is performed. Additionally, in accordance with an optional embodiment, the user is queried to approve the determined action before the action is taken. Control then continues to step S 170 . 
     In step S 170 , a determination is made whether the communication session is still active. If the communication is still active, control jumps back to step S 110 . Otherwise, control continues to step S 180  where the control sequence ends. 
     While the above-described flowcharts have been discussed in relation to a particular sequence of events, it should be appreciated that changes to this sequence can occur without materially effecting the operation of the invention. Additionally, the exact sequence of events need not occur as set forth in the exemplary embodiments. The exemplary techniques illustrated herein are not limited to the specifically illustrated embodiments but can also be utilized with the other exemplary embodiments and each described feature is individually and separately claimable. 
     The above-described system can be implemented on wired and/or wireless telecommunications devices, such as a telephone, mobile phone, PDA, a wired and/or wireless wide/local area network system, a satellite communication system, or the like, or on a separate programmed general purpose computer having a communications device(s) or in conjunction with any compatible communications protocol(s). 
     Additionally, the systems, methods and protocols of this invention can be implemented on a special purpose computer, a programmed microprocessor or microcontroller and peripheral integrated circuit element(s), an ASIC or other integrated circuit, a digital signal processor, a hard-wired electronic or logic circuit such as discrete element circuit, a programmable logic device such as PLD, PLA, FPGA, PAL, a communications device, such as a phone, any comparable means, or the like. In general, any device capable of implementing a state machine that is in turn capable of implementing the methodology illustrated herein can be used to implement the various communication methods, protocols and techniques according to this invention. 
     Furthermore, the disclosed methods may be readily implemented in software using object or object-oriented software development environments that provide portable source code that can be used on a variety of computer or workstation platforms. Alternatively, the disclosed system may be implemented partially or fully in hardware using standard logic circuits or VLSI design. Whether software or hardware is used to implement the systems in accordance with this invention is dependent on the speed and/or efficiency requirements of the system, the particular function, and the particular software or hardware systems or microprocessor or microcomputer systems being utilized. The communication systems, methods and protocols illustrated herein can be readily implemented in hardware and/or software using any known or later developed systems or structures, devices and/or software by those of ordinary skill in the applicable art from the functional description provided herein and with a general basic knowledge of the computer and communications arts. 
     Moreover, the disclosed methods may be readily implemented in software that can be stored on a storage medium, executed on a programmed general-purpose computer with the cooperation of a controller and memory, a special purpose computer, a microprocessor, or the like. In these instances, the systems and methods of this invention can be implemented as program embedded on personal computer such as an applet, JAVA® or CGI script, as a resource residing on a server or computer workstation, as a routine embedded in a dedicated communication system or system component, or the like. The system can also be implemented by physically incorporating the system and/or method into software and/or hardware system, such as the hardware and software systems of a communications device or system. 
     It is therefore apparent that there has been provided, in accordance with the present invention, systems and methods for initiating an action based on a detected message. While this invention has been described in conjunction with a number of embodiments, it is evident that many alternatives, modifications and variations would be or are apparent to those of ordinary skill in the applicable arts. Accordingly, it is intended to embrace all such alternatives, modifications, equivalents and variations that are within the spirit and scope of this invention.
