Description

  The present invention relates to a presence service system that notifies another user of a user's communication state, communication address, and the like, and in particular, SIP (Session Initiation Protocol) in IMS (IP Multimedia Subsystem) standardized by 3GPP (Third Generation Partnership Project). ) And a presence display method used in the system.

  Presence service is a service that allows you to know the communication status and communication address of the other party, and is already popular on the Internet. By combining this presence service with existing circuit-switched telephone voice communications or multimedia communications such as instant messaging, end users can change their communication methods according to their presence status. Communication service can be used.

  Here, in 3GPP, based on a protocol (communication procedure) standardized by IETF, a presence service is realized on IMS using SIP technology and standardized in 3GPP Release 6.

  Presence information is represented by a presence tuple (TUPLE, combination). There are three main types of presence tuples:

(A) Communication status information (online / offline status)
(B) Information on communication address (communication means: telephone, SMS (Short Message Service), e-mail, instant message, etc.) and communication address (phone number, e-mail address, SIP URI, etc.)
(C) Other presence information (free text, etc.).

  A presence model including presence tuples is defined in RFC 2778 of IETF (see, for example, Non-Patent Document 1).

  Further, a specific format of presence information is defined in RFC3863 (PIDF: Presence Information Data Format) and an extended version thereof, RFC4480 (RPID: Rich Presence Information Data) (for example, Non-Patent Document 2). , 3).

  In addition, the IMS provides a SIP routing function, a subscriber authentication function, a billing function, and the like as a platform. When using presence on IMS, presence-specific applications are realized by a SIP application server (SIP-AS) on the IMS ISC interface (see, for example, Non-Patent Document 4).

  In the presence service, the side that provides the presence information is referred to as “Presentity”, and the side that monitors is referred to as “Watcher”. The SIP protocol is used to convey presence information. (1) SUBSCRIBE: Start of monitoring of presence status of Watcher (subscription), (2) NOTIFY: Notification of presence status of Watcher, (3) PUBLISH: Presentity The presence status can be notified by a SIP message such as transmission of the presence status.

  Further, information such as a list of approval policies for the presence monitoring of the Watcher accompanying the presence server is stored in an XDMS (XML document management server) in the form of an XML document. An HTTP-based protocol called XCAP (XML Configuration Access Protocol) defined in RFC4827 is used to add, change, and delete setting information in these XML documents.

  However, in a conventional presence service system using SIP, the type of user presence information is defined in RFC 2778 and the like, and here, it is assumed between terminals in the same network using SIP. For this reason, there is a problem that there is no kind of information relating to the communication state of terminals connected to different networks, and the presence service cannot be used.

  Further, the conventional system has a problem that it is difficult for the user to understand the contents of the presence information because only the text information can be displayed indicating the communication state of the user.

  The present invention has been made in view of the above points, and it is an object of the present invention to provide a presence service system and a presence display method that can provide presence information for a heterogeneous network and can display presence information using an image. And

  The presence service system according to the present invention includes a first terminal that performs communication using SIP in a first network and a second terminal that is used in a second network different from the first network. A presence service system for displaying presence information between, a holding means for holding presence information of the first terminal, an image registration means for registering an image corresponding to the presence information of the first terminal, In response to a display request from the second terminal, the presence information of the first terminal held in the holding means is converted into a format that can be sent to the second network, and the presence information is supported. Corresponding conversion for retrieving an image from the image registration means, sending the image to the second terminal, and displaying it as presence information of the first terminal Characterized by comprising a stage.

  According to such a configuration, in presence service using SIP, presence information of the first terminal is sent to the second terminal in response to a display request from the second terminal connected to the heterogeneous network. The image is converted into a format that can be sent to the connected network, and an image corresponding to the presence information is sent to the second terminal and displayed as presence information of the first terminal.

  According to the present invention, provision of presence information for a heterogeneous network is provided by converting the presence information of the first terminal based on SIP into a format that can be sent to a second terminal connected to the heterogeneous network. Is possible.

  Furthermore, by providing means for registering an image corresponding to the presence information of the first terminal and sending the registered image to the second terminal, the presence information can be displayed using the image.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an overall configuration of a presence service system according to an embodiment of the present invention.

  This presence service system enables the presence information of a terminal used in the first network 11 to be transmitted to a terminal used in the second network 12, which is another network, and the presence information is transmitted by the user. It can be expressed using an arbitrarily registered image.

  Here, the first network 11 is assumed to be IMS. That is, the first network 11 is a so-called “managed network” operated by a carrier such as a communication operator, and is a terminal (hereinafter referred to as a SIP terminal) based on SIP defined in RFC2778. ) 13a and 13b are connected.

  On the other hand, the second network 12 is assumed to be a wide-area communication network such as the Internet. The second network 12 is connected to general-purpose personal computers (hereinafter referred to as PCs) 14a and 14b having a function of connecting to the Internet.

  In the following, it is assumed that a first user (referred to as user A) has two SIP terminals 13a and a PC 14a, and a second user (referred to as user B) has a PC 14b. Then, the presence status of the user A on the first network 11 (specifically, presence information of the SIP terminal 13a of the user A used in the first network 11) is transferred to the second network 12 which is a heterogeneous network. Description will be made assuming that the data is displayed on the connected user A's PC 14a.

  Further, the PC 14a is browsing a blog created by the user A himself, and on the blog, the presence status of the user A is expressed using an image such as an avatar created by the user B who is a third party. Assume that it is displayed as part of a part.

  As shown in FIG. 1, the first network 11 includes a presence server 21 that holds the presence status of the user A (presence information of the SIP terminal 13a), a content server 22 that holds an image created by the user B, and user information. And an XDMS (management server) 23 that associates images with images and manages them in an XML format, and a SIP application server (SIP-AS) 24 that converts signals received by the SIP protocol and transmits them to the second network 12. Yes.

  On the other hand, a blog server 25 and a Web registration server 26 on the Internet are connected to the second network 12. Furthermore, an authorization server 27 for performing image authorization processing is provided between the Web registration server 26 and the content server 22.

  In such a configuration, various images that can be used for the presence service are registered in the content server 22. In the example of FIG. 1, an image such as an avatar created by the user B is registered in the content server 22. On the other hand, the user A who is a presentity can acquire an arbitrary image from the content server 22 and use it for notification of his / her presence status.

  Here, when the first network 11 is IMS and the second network 12 is the Internet, an image arbitrarily created by the user B on the second network 12 does not conform to the operating conditions of the first network 11. Sometimes. Therefore, in this system, the authorization server 27 is provided, and the image registered by the user B via the second network 12 is checked for its image format / size, virus, policy, etc. 11 only adopts a configuration that conforms to the above operating conditions.

  FIG. 2 shows a function group held by the first network 11 and other function groups. As shown here, regarding the authorization server 27, the first network 11 may have, or a third-party organization or the like may have it separately from the figure.

  In the figure, reference numeral 22a denotes an image database (image DB) in which the content server 22 is provided, and images certified as appropriate by the certification server 27 are accumulated.

  As shown in FIG. 3, each of the servers 21 to 27 includes a computer including a CPU 31, a program memory 32, a data memory 33, a communication I / F (interface) 34, and the like. A program memory 32 provided in each of the servers 21 to 27 stores a program for realizing the function of each server.

  In particular, in the SIP application server 24 that is a feature of this system, a corresponding conversion program is stored in the program memory 32. This correspondence conversion program takes the correspondence between the presence information of the first terminal (here, the SIP terminal 13a) premised on SIP and the presence information of the terminal (here, the PC 14a) connected to the heterogeneous network to the heterogeneous network. Perform the conversion process.

  In the XDMS 23 that is the management server, the matching program is stored in the program memory 32. This matching program associates an image used for presence information with a user who uses the image.

  The operation of each function realized by this system will be described in detail below with reference to FIGS.

  In addition, the circled number in a figure has shown the process sequence. Further, the processing procedures shown in the following sequence diagrams are executed by reading a predetermined program stored in the program memory 32 by a control unit (CPU) 31 mounted on each server or terminal.

(A) User Registration Function First, the operation of the user registration function of this system will be described.

  FIG. 4 is a system configuration diagram showing a flow when user A registers presence using the SIP terminal 13a on the first network 11, and FIG. 5 is a sequence diagram thereof. Here, a method of realizing the presence information (viewable list etc.) of the user A by XCAP is shown. This is the same as the function realized by the IMS Gt interface defined in 3GPP, and is also defined in the OMA presence specification, which is a standardization organization.

  As shown in FIG. 5, a registration request is made from the SIP terminal 13a of the user A to the XDMS 23 using the XCAP protocol (step S101). Thus, the XDMS 23 registers the information (profile) of the user A in the management memory (the data memory 33 in FIG. 3) (step S102), and then returns a registration completion notification to the SIP terminal 13a that is the request source (step S102). Step S103).

(B) Image Registration Function Next, the operation of the image registration function of this system will be described.

  FIG. 6 is a system configuration diagram showing a flow when the user B registers an arbitrary image using the PC 14b on the second network 12, and FIG. 7 is a sequence diagram thereof. Here, since the image is registered through the second network 12 different from the first network 11, a function for checking the appropriateness of the image is required. The authorization server 27 corresponds to the check function.

  As shown in FIG. 7, an image such as an avatar created by the user A is uploaded to the Web registration server 26 from the PC 14b of the user B using the HTTP protocol (step S201). The Web registration server 26 transfers this user B image to the authorization server 27 (step S202).

  Here, the certification server 27 checks the format, size, virus, policy, etc. of the image (step S203). Then, when it can be recognized that the image is appropriate, the image is transferred to the content server 22 (step S204). The content server 22 checks the address and the like of the authorization server 27 that is the image transfer source (step S205), and stores the image in the image database 22a (step S206).

  In this way, when the image of user B is authorized and stored in the image database 22a of the content server 22, a notification of the completion response is sent from the content server 22 to the authorized server 27 and the Web registration server 26. And sent to the PC 14b (steps S207 to S209).

(C) Image Use Registration Function Next, the operation of the image use registration function of this system will be described.

  FIG. 8 is a configuration diagram when the user A registers an image to be used for his blog on the second network 12 using the PC 14a, and FIG. 9 is a sequence thereof. In this image use registration, the blog part is set on the blog side after matching an image (here, an image created and registered by the user B) and user information (here, the information of the user A).

  As shown in FIG. 9, the use registration of the image is requested to the content server 22 from the PC 14a of the user A using the HTTP protocol (step S301). The content server 22 registers the information of the requesting user A (step S302), and then returns a usage registration completion notification to the PC 14a (step S303). And it will be in an available state by the predetermined login procedure using ID, a password, etc. (steps S304-S306).

  Here, when the user A selects a desired image (here, an image created by the user B) from various images registered in the image database 22a of the content server 22 by a predetermined operation, the content server 22 The XDMS 23 is requested to match the selected image with the user A (step S308).

  Thus, the XDMS 23 holds matching information between the selected image and the profile of the user A, and returns a completion notification to the content server 22 (step S309). Upon receiving this completion notification, the content server 22 generates the image as a blog part (step S310), and returns the generation completion notification to the user A's PC 14a (step S311).

  Subsequently, the user A logs in to the blog server 25 by a predetermined operation (steps S312 to S314), and sets the blog part acquired from the content server 22 as his / her blog (steps S315 and S316).

  In this way, an image created by the user B can be acquired as a blog part. This blog part (image) is used to notify the presence status of the user A as will be described later.

(D) Image browsing function Next, the operation of the image browsing function of this system will be described.

  FIG. 10 is a system configuration diagram showing a flow when the user A actually browses a blog using the PC 14a on the second network 12, and FIG. 11 is a sequence diagram thereof. Here, an image such as an avatar indicating the presence status of the user A during browsing the blog is acquired from the content server 22 via the SIP application server 24.

  As shown in FIG. 11, the user A accesses the blog server 25 through the PC 14a by a predetermined operation and browses his / her blog (steps S401 and S402). At that time, a search request for an image used for the blog is sent from the PC 14a to the SIP application server 24 (step S403).

  Regarding the image search at this time, the operation on the PC 14a side can be simplified by using a simple interface such as REST. In response to the request from the PC 14a, the SIP application server 24 executes the following processing.

  That is, the SIP application server 24 performs the conversion process by taking the correspondence between the presence information of the SIP terminal 13a used on the first network 11 and the presence information of the PC 14a used on the second network 12. First, the presence status of the user A is inquired to the SIP application server 24 (steps S404 to S407). The “presence status of user A” here refers to presence information of the SIP terminal 13 a used on the first network 11.

  Next, the SIP application server 24 accesses the XDMS 23 and obtains information that matches the image and the presence status of the user A (steps S408 and S409). Subsequently, the SIP application server 24 inquires of the content server 22 about the storage location of the image using the matching information (step S410).

  In response to this inquiry, when the URL (Uniform Resource Locators) indicating the image storage location is sent from the content server 22, the SIP application server 24 transfers this to the requesting PC 14a (step S412).

  As a result, the PC 14a acquires an image from the content server 22 based on the URL received from the SIP application server 24 (steps S413 and S414), and displays it as a part of the blog.

  As described above, according to the present system, presence information of a terminal based on SIP can be provided to a terminal connected to a heterogeneous network in a presence service using SIP. As a result, the degree of freedom of the presence service is expanded and presence information can be displayed without any trouble even between different types of terminals.

  In addition, by associating an arbitrary image registered in the content server 22 with the presence information, it is possible to express not only characters but also images in an easy-to-understand manner.

  In addition, when creating a blog on the Internet, it is possible to use the user's presence status uniquely using a favorite avatar image.

  In addition, when registering an image, by checking its appropriateness, it is possible to ensure reliability of an image registered through a network other than a network based on SIP and use it for a presence service.

  Further, when the presence information of the first terminal (SIP terminal 13a) belonging to the first network 11 is sent to the second network 12, the presence of the second terminal (PC 14a) belonging to the second network 12 is sent. By taking the correspondence with the information, it becomes possible to display the presence information of the first terminal in real time while the second terminal is browsing the blog.

  Note that more advanced services can be realized by using Web services such as Web 2.0 and SNS.

  Further, by developing the image itself registered from the second network 12 as a product, it can be a tool for visualizing the presence status of the first network 11. Therefore, for example, if the user of the first network 11 pays an image usage fee, the number of users who provide images increases, and display of a wider variety of presence states can be realized.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
