Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority to European Patent Application No. 16176994.8, which was filed on Jun. 29, 2016. The entirety of this European patent application is incorporated by reference herein. 
       FIELD OF THE INVENTION 
       [0002]    The present invention relates to a method of providing a recent call list, and also relates to a software product, a telecommunications device and a telecommunications system. 
       BACKGROUND OF THE INVENTION 
       [0003]    A telecommunication device can provide a recent call list that includes calls recently received or initiated by the telecommunications device. A recent call list is generally understood as a list including calls recently received and/or initiated using a telecommunications device, and generally allows a user to select particular entries, and initiate further calls based on such selection. The recent call list typically identifies telephone calls that were previously made by the device. In other words, a recent call list as generally known in the art is limited to showing the history of past calls. 
         [0004]    For example, WO 2014/187288 A1 relates to a call log invoking method. A call log invoking request sent by a client comprises an action field for indicating an invoking operation and a type field for indicating that a data type is a call log. WO 2008/130101 A1 relates to providing various call services by using a hot key. EP 1 621 983 A2 relates to more easily find an item within a plurality of items of the same kind such as communications, contacts, folders, files, messages, applications, or the like, by providing a recent item list of items that were recently used. Correspondences (incoming and outgoing) may be matched to a corresponding contact stored in a device. A recent item may be shown only once in the recent items list. 
       SUMMARY OF THE INVENTION 
       [0005]    A technical problem underlying the present invention is enhancing functionality of a recent call list. A further problem underlying the present invention is enhancing control of an integrated system facility management, surveillance, and monitoring by use of a telecommunications device. 
         [0006]    The problem(s) mentioned above are at least in parts solved by the features of the appended independent claims. Further developments and advantageous embodiments of the invention are set forth in the dependent claims. 
         [0007]    A first aspect, or embodiment, of the present invention relates to a method of providing a recent call list of calls recently received or initiated by a telecommunications device. Information on recent services which are services recently handled by or using said telecommunications device other than calls are incorporated as entries in a recent call list of said telecommunications device. Each entry of said recent call list is formed by a data structure including a plurality of data fields, wherein each data field includes a data value. An entry representing a recent service other than a call in said recent call list includes a service code identifying said recent service, as a data value. In the above aspect, recently generally means in the past. Handling of a service may include, without being limited to, initiating, controlling, monitoring, receiving reports about. A value may generally be comprised of or interpretable as any sort of character string, numeral, logical, or whatsoever, or even an array thereof. A service other than a call may be a service other than a telecommunications service at all such as door opening, facility management or surveillance, entry control, environmental surveillance, machine control, or others. 
         [0008]    It should be understood that a call as used herein to describe embodiments of the present innovation described in this patent application can include a telephone call, but can also include other telephoning communication events such as fax, SMS (text messaging, short message service messaging, etc.) and can also include other types of telecommunications exchanges or messaging by email, skype, twitter, facebook, xing, a blog, or the like, and may include audio, video, text, or other content. A call may therefore include a telecommunications exchange involving the telecommunications device that may be defined by use of an application stored on that device and use of a service accessible via an application programming interface (“API”) or other type of interface with a remote service hosted by one or more remote servers (e.g. remote computer devices having hardware including a processor, memory, and at least one transceiver type device) accessible via a network (e.g. the internet, etc.) that may be utilized via that application. A call in the sense of the application can be understood to be represented by a call identifier of another side of the call and preferably includes other contact information, in the recent call list. 
         [0009]    In preferred embodiments, a data field may include a data field identifier identifying its respective data value (e.g. each entry may be understood as a data set wherein a place intended for a specific kind of data value is a data field which is uniquely identified by a respective data field identifier). A kind of data value may be any data in relation to a call, such as date/time, duration, other party (called, calling), direction of call (in, out, incoming, outgoing, etc.), and absolute call count in device, etc. The sum of entries may thus be provided in the form of a database or other type of datastore. As an example, the data structure may be predefined by JavaScript Object Notation (JSON), or other data exchange format. In any of such data exchange formats, the data values of each data field are information used for clearly and unambiguously identifying a call, and providing further information thereon. At least, such information allows to identify another side of the call, in particular to an extent to be able to initiate a further call with said other side. Preferably, such information also includes other aspects of a call such as date and/or time of the call. A data field identifier may be a mere field count, or be a character string including a name or shortcut of a specific kind of data value such that a data field identifier indicates a place intended for a specific kind of data value, i.e., for a specific information relating to a call. Thereby, call information may be found, interpreted and used by a call handling device or software stored in non-transitory memory of that device that is run by a processor of that device. 
         [0010]    In preferred embodiments, said service code may be included at a place intended in said entry for a call identifier of another side of a call, and include a distinguisher allowing for distinguishing a service code from a call identifier. Said distinguisher may be a prefix or suffix, and may include a character or text not expected for a call identifier. It will be noted that each type of service may be addressed by a unique service code just like a certain other party may be addressed by a unique call identifier. It will be noted that a call identifier may include, without being limited to, any of a telephone number, a telefax number, an email address, or any other type of electronic address. 
         [0011]    In preferred embodiments, an entry representing a recent service other than a call in said recent call list may include a plain text description of said recent service as a data value. Said plain text description may be included at a place intended in said entry for contact information of another side of a call, said contact information including at least a name and a call identifier, and be in a format expected at that place. 
         [0012]    In preferred embodiments, an entry representing a recent service other than a call in said recent call list may include a second level detail of said recent service as a data value. Said second level detail may be included at a place intended in said entry for a second level detail of a call, and be in a format expected at that place. Second level detail of a call may for example include, without being limited to, detail of whether a call was answered, not answered, rejected, or ran into a busy terminal. Second level detail of a service other than a call may for example include, without being limited to, a result of the service. 
         [0013]    In preferred embodiments, an entry representing a recent service other than a call in said recent call list may include a service type of said recent service as a data value. Said service type may be included at a place intended in said entry for a call type of a call, and be in a format expected at that place. A type of a call may for example include, without being limited to, detail of whether a call was outgoing or incoming. 
         [0014]    In preferred embodiments, an entry representing a recent service other than a call in said recent call list may include follow-up service information on a follow-up service which is a service to be activated upon selection of said entry by a user, as a data value. Said follow-up service information may include a service code identifying said follow-up service. 
         [0015]    In preferred embodiments, said recent call list may be displayed or displayable upon user choice on a display device, and if an entry representing a recent service other than a call is found in said recent call list, at least one of the service code of said recent service, and a plain text description assigned to said service code, is displayed for such entry in displaying said recent call list. In other words, just data fields which are used for displaying call details are also used to display contents of a recent service other than a call. The appearance in a displayed recent call list would be quite the same format for recent calls and recent services other than calls. 
         [0016]    In preferred embodiments, said recent call list is sorted or sortable upon user choice by at least one of a date, call identifier of another side of a call, name and/or other contact information, and service code. 
         [0017]    In preferred embodiments, said entries regarding one same service functionality are grouped or groupable together upon user choice in said recent call list. In preferred embodiments, said telecommunications device may be a telecommunications terminal device. Said recent service and/or a follow-up service may be executed or executable by a telecommunications server such as a PBX or the like. As an alternative or additional option, remote services may address or be addressable by a telecommunications server such as a private branch exchange (PBX) of telecommunication switch device via a local area network (LAN) or a wide area network (WAN). Such networks may be wireless, wired, or include transmission paths that include both wired and wireless transmission paths involving a plurality of intermediate nodes (e.g. gateways, base stations, access points, routers, etc.). 
         [0018]    In preferred embodiments, a data structure may be provided comprising assignments of service codes and additional information for identifying and/or describing a service or kind of service. Said additional information may comprise at least one of a plain text description, service type, service code of a follow-up service. Said data structure may be provided in the form of a database, table, or the like. 
         [0019]    A second aspect, or embodiment, of the present invention relates to a software product for providing a recent call list of calls incoming to and outgoing from a telecommunications device, said software product being stored on a non-transitory computer-readable medium, preferably being directly loadable into an internal memory of a computer. The software product of this aspect comprises program code for performing the steps of the method of the afore-described first aspect of the present invention at said telecommunications device when said software product is executed by said computer. Said computer may be embodied by said telecommunications device or a server connected to said telecommunications device. It will be noted that the software product may be embodied by, without being limited to, a stand-alone software, software package, plug-in, add-on, app or the like to be included in or used by or co-executed with or enabling or enhancing functions of a telecommunications software, or may constitute or be part of or include a basic operating program of a telecommunications device, unit, server, system, or the like. 
         [0020]    A third aspect, or embodiment, of the present invention relates to a telecommunications device, preferably a telecommunications terminal device (e.g. a computer, a desktop computer, a personal computer, a laptop computer, a telephone, a smart phone, an electronic tablet device, televisions, or other type of endpoint device having hardware that includes non-transitory memory (e.g. flash memory, a hard drive, etc.), a processor (e.g. a central processing unit, a microprocessor, etc.) configured for use by a user to initial calls and/or receive calls for engaging in telecommunications activities with others, and at least one transceiver unit (e.g. at least one receiver and at least one transmitter). The telecommunications device of this aspect is adapted to execute the method of the afore-described first aspect of the present invention. Adaptation may be provided by implementing the program code of the software product of the afore-described second aspect of the present invention. It will be noted that the telecommunications terminal device in some embodiments may be any kind of device suitable to perform telecommunication events, such as a mobile phone, smart phone, portable computer, desktop computer, a telecommunications server such as a PBX, or the like. 
         [0021]    A fourth aspect, or embodiment, of the present invention relates to a telecommunications system comprising at least one telecommunications device, preferably at least one telecommunications terminal device. The telecommunications system of this aspect is adapted to execute the method of the afore-described first aspect of the present invention. Adaptation may be provided by implementing the program code of the software product of the afore-described second aspect of the present invention on at least one instance included in said telecommunications system. The telecommunications system may comprise at least one server for executing services other than telecommunications services. The server may be or included in or comprise a PBX. Said services other than telecommunications services may include at least one of a door opening service, door monitoring service, facility management service, surveillance or monitoring services, or the like. The telecommunications system may further comprise at least one of a telecommunications server for executing telecommunications services. It will be noted that the server and the telecommunications server may be, but need not to be, the same device. 
         [0022]    Embodiments (or aspects) of the present invention may as well be embodied by a computer program including instructions configured for storage within memory of a device to cause that device to o perform the steps of the afore-described method of the first aspect when said computer program is loaded in or executed by said device, or by a digital data carrier having electrically readyble control signals which are designed to operate with a programmable device, said control signal being designed and adapted to cause the device to perform the steps of the method of the afore-described first aspect of the present invention. In any such cases, the device may also be embodied by the telecommunications device of the afore-described third aspect. 
         [0023]    With embodiments of the present invention, a concept is introduced that services activated or addressed via service codes can be incorporated within a recent call list so that such services appear just like telephone calls in the call history. In other words, the functionality of a well-known recent call list is enhanced in that it may be understood as a recent-calls-and-services history, and each service event appearing as an entry in the history may be selected just as a call so as to inspect its details, or activate some follow-up service which may be predefined or suggested as part of the same entry of the recent call list. This also enhances control of an integrated system facility management, surveillance, and monitoring by use of a telecommunications device. 
         [0024]    Further aspects (or embodiments), objects, advantages, and details of the present invention will become more apparent from the following description of specific exemplary embodiments of the invention and respective illustration thereof in the appended drawings.

       DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS 
       [0033]      FIG. 1  shows a general example of a telecommunications environment  100  according to an exemplary embodiment of the present invention. 
         [0034]    As shown in  FIG. 1 , the telecommunications system includes a number of communications terminal devices  102 . Each terminal device  102  may in general be understood as a computer device that includes a CPU, ROM, RAM, internal and/or external busses, interfaces and controllers, power supply etc. and is connected to (or includes) a display unit  104  for displaying contents as results of software running on terminal device  102 . For instance, software stored in non-transitory memory can be executed by a processor of the terminal device  102  such that the device performs a method defined by the code of the software. Graphical user interface information can be displayed based on such software via the display unit to facilitate displaying of output to a user and receipt of input from a user utilizing one or more input devices of the terminal device (e.g. touch screen feature of the display unit  104 , stylus, button, keypad, keyboard, pointer device, mouse, etc.). 
         [0035]    In the present example, a recent call list  106  is displayed on display unit  104  of one of the terminal devices  102 . Each terminal device  102  may also be connected to (or include) I/O facilities such as a writing unit  108  such as a keyboard, a pointing unit  109  such as a mouse, and a voice unit  110  such as a head set. Terminal devices  102  are connected to a PBX  112  directly or via a local area network (not explicitly shown), or implemented in PBX  112 . 
         [0036]    Moreover, a door opening service  114  and a facility management service  116  are connected to a PBX  112  directly or via the local area network, or implemented in PBX  112 . PBX  112  is connected or connectable to a wide area network (WAN)  118  such as the internet or the like. For connecting to WAN  118 , PBX  112  may be assumed to be connected to or include some routing/gateway facility (not explicitly shown) which may also manage the local area network mentioned above. Via WAN  118 , PBX  112  is further connected to a telecommunications provider  120  and a remote facility management system  122 . The terminals  102  and the PBX  112  may be understood as a telecommunications system in the sense of the present invention. 
         [0037]      FIG. 2  shows an excerpt of recent call list  106  as it shows up on display  104  of a telecommunications device  102  used by a user (see  FIG. 1 ), including typical examples of the features introduced according to the present invention. The recent call list  106  includes a number of entries which will be generally addressed by reference sign  202 , in the following. In the excerpt showing up in  FIG. 2  seven individual entries  202 . 1 , . . . ,  202 . 7  are visible of which entries  202 . 1 ,  201 . 2 ,  202 . 5  and  202 . 7  relate to recent calls, entries  202 . 4  and  202 . 6  relate to telecommunication services other than telephone calls, and entry  202 . 3  relates to a service other than a telecommunication service (and, obviously, other than a telephone call). 
         [0038]    Each entry  202  displayed in the excerpt of the recent call list  106  is divided into several display areas as exemplarily indicated by dotted border lines in the first entry  202 . 1 , including a name area  204 , a number area  206 , a date area  208 , a time area  210 , and a selection area  212 . If an entry relates to a call such as, e.g., entry  202 . 1 ,  202 . 2  and others, the name area  204  shows a name of a person (or more generally, of a party which also may be a company, society or whatever entity) to which or from which the call was directed, the number area  206  shows a number (or more generally, a party identifier) of the party to which or from which the call was directed, the date and time areas  208 ,  210  show a date and time of when the call was made or received, and selection area  212  includes some selection symbol which is selectable by, e.g., pointing unit  109  of  FIG. 1 . If an entry relates to a service other than a call as exemplified by entry  202 . 3 , the name area  204  shows a short description  214  of the service, the number area  206  shows a service code  216 , and the date and time areas  208 ,  210  show a date and time when the service event has happened. In any case, selecting the section symbol in selection area  212  leads to a further action associated with the entry, such as showing its details or executing some follow-up service being prescribed by default or varying depending on a situation, or being selectable by user choice. 
         [0039]    As shown in  FIG. 2 , a service code  216  showing up in the number area  204  of entries  202 . 3 ,  202 . 4  and  202 . 6  has a format clearly showing that the number is not a telephone number or other call identifier. In the present example, a service code is prefixed by a “*” character (asterisk sign). It will be noted that the invention is not limited to a “*” prefix for this purpose. 
         [0040]    The excerpt of recent call list  106  shown in  FIG. 2  is sorted by date and time such that the most recent entry shows up first. However, there is no limitation in this regard. In particular, the list may be generated as a pure data structure, each entry identified by some entry identifier or count not showing up when displayed, and may be sorted by any other criteria automatically, by default, or upon user choice for display. 
         [0041]    The concept of introducing service codes  216  inside recent call list  106  opens a new view in presenting recent calls in telephone systems (herein, an entry of a recent call list may also be addressed as a “recent”, for ease of language). This can enable users to see their activated features such as opening a door, forwarding a call, transferring a call, granting access to a user to reach an outside line, parking a call etc. In that essence, recents become a more common history of exactly what a user has done with his or her device. 
         [0042]    In the following, an approach on the method of how service codes of any kind can be incorporated in recents of a recent call list so a user can handle them in the same way as recent calls, will be described. This description is oriented for showing the different attributes that can be deducted from such an approach:
       showing the service codes and translating to the actual code listing up the history;   what happens when the user selects a recent entry that in fact is a service other than a call or, more generally, other than a telecommunication service; and   how service codes can be grouped depending on type.       
 
       &lt;Showing Services Codes in Recents&gt; 
       [0046]    First of all, an exemplary principle data structure of an entry in recent call list  106  will be described by way of example.  FIG. 3  shows a data structure  300  representing a recent call list entry  106  as shown in  FIG. 1 . The data structure  300  may be understood as a listing in JSON format. An overview of the JSON data interchange format may be found in “The JSON Data Interchange Format”, Standard ECMA-404, 1st Edition/October 2013, ecma international, with further references. The listing in  FIG. 3  includes a JSON response showing how a recent call entry  106  may be represented in an PBX system. It will be noted however that JSON is just one example of a data structure to describe the way data is received. Other forms may apply as well. The JSON format is used, for example, in Asterisk which is a common telephone system. Of course, the present invention is not limited to this application. 
         [0047]    In JSON as in many other data interchange formats, a data structure (which may also be referred to as a data set or object) may be listed in text form which is written in lines. In the present example as shown in  FIG. 3 , the data structure  300  includes lines  302 - 326  counted in even numbers. The first and last lines  302 ,  326  include an opening token  354  and a closing token  356 , respectively (here, left and right curly brackets) while lines  304 - 324  include respective data fields  352 . It will be noted that data fields  352  are separated from each other by a data field separator (here, a comma). Each data field  352  is composed of a data field identifier  358  (the “name” of the data field) and a data value  360 . Data field identifiers  358  and data values  360  are character strings (words) framed by quotation signs (double inverted commas). A data filed identifier  358  is followed by a data value  360 , separated by a separator (colons). If a data value  360  includes more than one item such as for the destination field in line  312 , the items are separated from each other by another separator (backslash). It will be noted that listing in lines is only for the human reader for ease of recognition but is not necessary for automatic interpretation of the data structure  300 . In the following, a specific one of data fields  352  may also be referred to by its line count within the data structure  300 . 
         [0048]    As seen in  FIG. 3 , a JSON response of a recent call may include the data fields shown in table 1 below:

         [0049]    It is noted however that the above identifiers and contents are exemplary and may be defined as needed in a telecommunications device, system, or software, and even by a user. 
         [0050]    To include recent services other than calls in a recent call list, service codes can be incorporated in a recent call entry. A table which matches the service code activated with the actual service code can write in the recents the actual service in text mode. Recent&#39;s date and time are the same as any other recent call. 
         [0051]      FIG. 4  shows an example of a data structure  400  representing a recent call list entry  106  referring to a recent service other than a call, in a recent call list. This data structure  400  includes lines  402 - 428  where lines  404 - 426  include data fields and lines  402 ,  428  include opening and closing tokens, respectively. For further details on the data structure  400  which is similar to data structure  300  of  FIG. 3 , see the afore description. In this data structure  400 , the fields “dst” (line  410 ), “destination” (line  412 ), “disposition” (line  416 ), and “direction” (line  422 ) have been re-used for including content relating to the recent service, and a new data field “action” is included in line  426 . The “action” field  426  may be understood as a user-defined data field. Below table 2 includes how data fields match with a service code entry.

         [0052]    In the “direction” field  422  an application can decide if this entry is a service code or an actual call and it can handle the information likewise. 
         [0053]    All other fields remain the same as in recent calls. So even an application that does not distinguish the difference between call and service will show this information irrespectively of the content. 
         [0054]    In the listing of data structure  400  shown in  FIG. 4 , the number in the “src” field is the number of a user of the terminal device where the recent call list is provided, and the service code of a service initiated using this device is found in the “dst” field. However, it can be vice versa such that in case that the service is initiated by another side the service code is found in the “src” field, and the own number is found in the “dst” field in such case. 
         [0055]      FIG. 5  shows a flowchart of a process  500  of matching incorporating service codes in recent call list. As shown in  FIG. 5 , process  500  starts by recognizing a user action in step  502 . Then, in step  504 , a judgment is made as to whether a call or a service was included in the user action recognized in step  502 . If the judgment  504  leads to a call, an incoming/outgoing call handling is made in step  506 . If the judgment  504  leads to a service other than a call, a service code handling is made in step  508  which implies data exchange with a database  510 . Thereafter, the branches via steps  506 ,  508  are reunited, and a recent call list is provided in step  512 . 
       &lt;Service Code Selection&gt; 
       [0056]    When selecting a recent call either details are displayed or the selected number is called back. Similarly these two options will be applied when a service other than a call is selected. In case details are to be shown all information is obtained from the response. This is up to the application how to handle this information. It will be noted that selection of an entry may be done by touching a screen area (e.g., selection area  212  in  FIG. 2 ), pushing or pressing a key, expressing speech or gesture or whatever input option the employed terminal device may offer. In case user selects an entry of a recent service other than a call then not all same rules do apply as in the case of recent call. The differentiation is due to the fact that a dialing the same service code combination is not necessarily the same action required for all cases. 
         [0057]    For example, a user selects a feature code to open a door via use of an input device for providing the selection. This entry is registered as an open door action. When user selects this entry in the recent call list, then it makes little sense if the door opens again. It would make sense if the user watches the door from a video monitor or opens the speaker call of the door etc. The above example shows the necessity to define an additional field namely the “action” field shown in  FIG. 4  that can define another action (so-called follow-up action) from the one additionally registered. The information of whether a different action is necessary is held in a local database of the underlined communication system. 
         [0058]      FIG. 6  shows a flowchart of a process  600  on writing onto the “Action” field. The flowchart is an excerpt relating to steps  508  and  512  of process  500  shown in  FIG. 5  and analyzes in more detail one of the functions of service codes handler step  508 , as indicated by steps  602 ,  604 , and  606  which are part of service code handler step  508 . 
       &lt;Grouping Service Codes&gt; 
       [0059]    One additional functionality that can be provided is the grouping of consecutive service codes. Again in this case this functionality differs from the one of the consecutive calls. Taking as example the door opener feature there are many times that service codes might differ for the same functionality. For example, service code may contain a secret key. Different users can open the door with different keys from the same device. In that case the recent call list will differentiate the two service codes for the same function and will list up two different entries. Hence the field “destination” may become very important since this is the one that can generically provide the information of the actual feature code. In this point it is to be made clear that “destination” and “dst” are two levels of decision given in the application which can be used openly. In other words, is up to the application whether it would use the information provided from the JSON listing, since the latter&#39;s content could be taken as redundant information.
