Description

  The present invention relates to a service providing apparatus, a service providing method, and a service providing program.

  Conventionally, there is a so-called Web service as a service provided to a terminal connected to a network controlled by IP (Internet Protocol). Here, the Web service generally refers to a service that realizes application functions via a network by applying WWW (World Wide Web) related technology. For example, a terminal connected to the Internet receives IM (Instant Messaging) service, which is one of Web services, and realizes chat and image data sharing with other terminals connected to the Internet.

  In recent years, a service providing system that controls a service based on such a temporary communication relationship when the relationship with a communication partner is temporary (in the case of a relationship that changes to ad hoc) has also been disclosed. Specifically, a service providing system that controls terminal A, terminal B, and terminal C will be described as an example. The terminal A has a SIP phone that can communicate using a voice communication control protocol such as SIP (Session Initiation Protocol), and an information display function that can use a Web browser or the like.

  The service providing system in such a state connects the SIP phone of terminal A and the SIP phone of terminal B by SIP communication using SIP. Each of the SIP phone of terminal A and the SIP phone of terminal B collects call session information “CCC” indicating SIP communication, an IP (Internet Protocol) address included in the SIP communication, and the like. Subsequently, when the service providing system receives the call session information “CCC” or the IP address from the information display function (such as Java (registered trademark) script) of the terminal A by Web communication, the service providing system uniquely identifies the Web communication for the terminal A Web session information “123”, which is information for identifying, is paid out. Similarly, when the service providing system receives call session information “CCC” or an IP address from the information display function of terminal B via Web communication, Web service information “456” is paid out to terminal B.

  At the timing when the Web session information is paid out, the service providing system performs authentication using the IP address. Specifically, when the service providing system receives the call session information from the information display function of the terminal A, the service providing system receives the “IP address accessed by the information collecting function of the terminal A” and the call session information by the access. It is determined whether or not the “IP address used in SIP communication collected by the SIP phone of terminal A” matches. Then, when both addresses match, that is, when the IP address used by the terminal A for Web communication matches the IP address used by the terminal A for SIP communication, the service providing system sends a Web session to the terminal A. Give out information. Similarly, for the terminal B, the service providing system issues Web session information to the terminal B when the IP address used by the terminal B for Web communication matches the IP address used by the terminal B for SIP communication. .

  Then, the service providing system associates the Web session information “123” of the terminal A paid out to the call session information “CCC” with the Web session information “456” of the terminal B. After that, when the terminal A is accessing the service providing system by the Web communication to which the Web session information “123” is assigned, one terminal B performs the service by the Web communication to which the Web session information “456” is assigned. Assume that image data is uploaded to the providing system. In such a case, since the relationship between each of the terminals A and B is a relationship in which the same communication is established by SIP, the service providing system determines that the image data sharing is mutually recognized. As a result, the service providing system controls the service so that the image data uploaded by the terminal A is transmitted to the terminal B. Thus, when the relationship with the communication partner is temporary (in the case of a relationship that changes to ad hoc), the service can be controlled based on such a temporary communication relationship.

  However, in the conventional technology, when the IP address system used in SIP communication and the IP address system used in Web communication are different, a situation where authentication by the IP address cannot be performed occurs and the service cannot be provided. There was a problem.

  For example, when the IP address used in SIP communication is in IPv4 notation and the IP address used in Web communication is in IPv6 notation, the service providing system can access even from the same user terminal, Since the IP address is different, authentication is not permitted and Web session information cannot be issued. Therefore, the service providing system cannot control the service based on such a temporary communication relationship when the relationship with the communication partner is temporary.

  The information display function of each terminal is Java (registered trademark) script that realizes a Web browser function for HTTP, and does not target SIP or RTP (Real-time Transport Protocol). For this reason, it is necessary to incorporate a special function such as a stack for processing SIP into the information display function of each terminal. Therefore, the service providing system may not be able to correctly receive an IP address used in SIP communication from a terminal that does not use the information display function that does not have the special function, and a situation in which authentication by the IP address cannot be performed occurs. To do.

  The present invention has been made in view of the above, and is capable of providing a service based on a temporary communication relationship regardless of the performance of the terminal using the service and the IP address system. An object is to provide an apparatus, a service providing method, and a service providing program.

  In order to solve the above-described problems and achieve the object, the present invention provides a service providing apparatus that controls services on a network with respect to a plurality of terminals connected to the network, The telephone number used in the first communication connected between and the IP address used in the second communication connected between the plurality of terminals are stored in the association storage means in association with each other When the second storage unit receives a request for using the service and a request for using the service from one of the plurality of terminals in the second communication. First communication information acquisition means for acquiring first communication information for uniquely identifying the first communication established between the first communication terminal establishing the first communication and another first communication terminal And obtaining the first communication information The telephone number included in the first communication information acquired by the stage and the IP address acquired from the second communication from which the first communication information has been acquired by the first communication information acquisition unit are associated with each other, and A determination unit that determines whether or not the information is stored in the association storage unit; and when the determination unit determines that the terminal is stored in the association storage unit, the terminal that has transmitted the use request receives the service The second communication information for uniquely identifying the second communication performed when using the service with the providing device is associated with the first communication information acquired by the first communication information acquiring means. Two second communication information storage means stored in the two communication information storage means, and any two of the first communication information stored in the second communication information storage means are the same. Is provided using each of the second communication information stored in the second communication information storage means in association with each of the first communication information. Service providing control means for controlling the services to be associated with each other.

  Embodiments of a service providing apparatus, a service providing method, and a service providing program according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

[Explanation of terms]
First, key terms used in the following examples will be described. A “service” is a so-called Web service (a service that realizes an application function via a network by applying a WWW-related technology). In a network controlled by IP such as the Internet, a “service providing apparatus” controls a service, and a “terminal” connected to the network is provided with a “service”.

  By the way, the “service providing device” controls the service based on the relationship between each terminal, the relationship between the terminal and the service providing device, or the relationship between users who use the terminal. For example, in the IM service, it is assumed that a user who uses the terminal A and a user who uses the terminal B realize file sharing in the IM service. It is assumed that terminal A has uploaded a file to “service providing apparatus” while terminal B is accessing “service providing apparatus”. In such a case, the “service providing apparatus” transmits a file to the terminal B based on the relationship between the user of the terminal A and the user of the terminal B. That is, the “service providing apparatus” receives, for example, an input of a user ID and a password from a user of the terminal A, and an input of a user ID and a password from a user of the terminal B, so that the user of the terminal A And the user of terminal B are identified. Then, if the relationship between the identified user of the terminal A and the user of the terminal B recognizes that file sharing is mutually accepted, the “service providing apparatus” sends a file to the terminal B based on the relationship. Control the service to send.

  In addition, for example, in SNS (Social Networking Service), it is assumed that the user of the terminal A who is the site operator causes the user of the terminal B to browse the site. In such a case, the “service providing apparatus” controls browsing of the site by the user of the terminal B based on the relationship between the user of the terminal A and the user of the terminal B. In other words, the “service providing apparatus” is a relationship in which the user of the specified terminal A and the user of the specified terminal B are permitted to browse the site by the user of the terminal A by the user of the terminal B. If so, the service is controlled so as to permit browsing of the site by the user of the terminal B based on the relationship.

  Further, for example, it is assumed that a “service providing apparatus” that provides music information permits a user of terminal A to download music information. In such a case, the “service providing apparatus” controls the download communication by the terminal A based on the relationship between the user of the terminal A and the “service providing apparatus”. That is, the “service providing device” is a relationship between the identified user of the terminal A and the “service providing device” if the download communication by the user of the terminal A is permitted by the “service providing device”. Based on the relationship, the service provision is controlled so as to permit the download communication by the terminal A.

  As described above, the relationship between each terminal, the relationship between the terminal and the service providing device, or the relationship between users using the terminal has various aspects depending on the service content. The “device” still controls services based on these relationships.

  However, the conventional Web service has been provided on the assumption that such a relationship is registered in advance. For example, a conventional “service providing apparatus” registers a relationship between users in a buddy list in advance, and controls services such as chat and image data sharing based on the registered buddy list. On the other hand, the “service providing apparatus” in the present invention is not only a relationship such as a pre-registered buddy list, but also when the relationship with the communication partner is temporary (a relationship that changes to ad hoc). Based on such temporary communication relationship, services such as chat and image data sharing are controlled.

[Overall configuration of service provision system]
Next, the overall configuration of the service providing system according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an overall configuration of a service providing system according to the first embodiment. As shown in FIG. 1, the service providing system includes a terminal 200, a terminal 400, a SIP (Session Initiation Protocol) proxy 300, and a service providing apparatus 100. In addition to the above, the service providing system may include, for example, an HGW (home gateway).

  The terminal 200 has a SIP phone function for performing communication in the process of establishing communication by SIP (SIP communication) or communication established by SIP, and an information display function for using a Web service by a browser or the like. Further, the SIP phone and the PC may be realized by separate casings, or may be realized by a single casing. Since terminal 400 is similar to terminal 200, detailed description thereof is omitted here.

  The SIP proxy 300 is a server device that performs control related to SIP communication such as transferring a request from a terminal to another terminal. For example, the SIP proxy 300 transfers a request (INVITE) from the SIP phone function of the terminal 200 to the SIP phone function of the terminal 400, and a response (200 OK) from the SIP phone function of the terminal 400 to the SIP phone function of the terminal 200. Forward to. In this way, the SIP proxy 300 enables a voice call between the terminal 200 and the terminal 400.

  The service providing apparatus 100 controls the service based on the relationship between each terminal, the relationship between the terminal and the service providing device 100, or the relationship between users who use the terminal. For example, the service providing apparatus 100 controls a Web service exchanged between the information display function of the terminal 200 and the information display function of the terminal 400 in a state where the terminal 200 and the terminal 400 are SIP-connected. Note that the SIP proxy 300 and the service providing apparatus 100 may be realized by separate casings or may be realized by a single casing.

  In such a state, the service providing apparatus 100 of the service providing system accepts HTTP access from the information display function of the terminal 200 as a pre-stage for controlling the service based on a relationship that changes ad hoc between user homes (FIG. 1). (See (1)). Subsequently, the service providing apparatus 100 acquires the IP address in IPv6 notation used by the information display function of the terminal 200 from the received access, and temporarily registers the acquired IP address in association with a unique temporary address ( (See (2) in FIG. 1). Then, the service providing apparatus 100 transmits the temporary address associated with the IP address in IPv6 notation used by the information display function of the terminal 200 to the information display function of the access source terminal 200 (see (3) in FIG. 1). .

  Thereafter, the SIP proxy 300 of the service providing system receives from the SIP phone function of the terminal 200 the INVITE of the SIP addressed to the service providing apparatus 100 and including the temporary address input by the user or the like (FIG. 1). (Refer to (4)). Subsequently, the SIP proxy 300 transfers the SIP INVITE including the received temporary address to the service providing apparatus 100 (see (5) in FIG. 1).

  When the temporary address included in the INVITE received from the SIP proxy matches the temporarily registered temporary address, the service providing apparatus 100 obtains a telephone number (SIP-URI (Uniform Resource Identifier)) from the INVITE. Acquire and register the acquired telephone number and the IP address temporarily registered in association with the temporary address (see (6) in FIG. 1). Thereafter, the service providing apparatus 100 transmits a response (200 OK) to INVITE to the SIP phone function of the terminal 200 via the SIP proxy 300 (see (7) in FIG. 1).

  Further, the processes (1) to (7) are also performed between the service providing apparatus 100 and the terminal 400. Therefore, the service providing apparatus 100 can register the telephone number used by the SIP phone function of the terminal 400 and the IP address in IPv6 notation used by the information display function of the terminal 400 in association with each other.

  Thereafter, the service providing apparatus 100 displays the information on the terminal 200 on the condition that the SIP phone function of the terminal 200 and the SIP phone function of the terminal 400 are in SIP connection, that is, on the condition that they have an ad hoc relationship. When the Web service exchanged between the function and the information display function of the terminal 400 is controlled, authentication using the IP address is performed (see (8) in FIG. 1).

  Specifically, the service providing apparatus 100 pays out Web session information for uniquely identifying the Web service to each of the information display function of the terminal 200 and the information display function of the terminal 400 (6) in FIG. It is determined whether or not the access is from the IP address registered in. Then, the service providing apparatus 100 pays out Web session information for access from the IP address registered in (6) of FIG. Since an example of controlling the service based on the subsequent temporary communication relationship (relationship changing to ad hoc) will be described later, it is omitted here.

  As described above, in the service providing system according to the first embodiment, it is possible to register the correspondence between the IP address and the telephone number that are actually used as preprocessing for controlling the service based on the temporary communication relationship. . As a result, when controlling a service based on a temporary communication relationship, it is possible to provide a service based on a temporary communication relationship regardless of the performance of the terminal using the service and the IP address system. is there.

[Service providing system configuration]
Next, the configuration of each device included in the service providing system will be described with reference to FIGS. Here, it is assumed that the terminal configuration of the user's home is an integral type of both the SIP phone function and the information display function, and the case where the SIP proxy is a general-purpose SIP proxy is assumed. Only the service providing apparatus and one terminal will be described.

(Configuration of service providing device)
The configuration of the service providing apparatus in the service providing system will be described with reference to FIG. FIG. 2 is a block diagram illustrating the configuration of the service providing apparatus according to the first embodiment. As illustrated in FIG. 2, the service providing apparatus 100 includes a communication control I / F unit 110, a storage unit 120, and a control unit 130.

  The communication control I / F unit 110 includes a general interface and library for HTTP (HyperText Transfer Protocol) communication, and transmits and receives information to and from the terminal 200. Specifically, the communication control I / F unit 110 performs communication in which a call session information receiving unit 132 (to be described later) receives call session information from the terminal 200, and a Web session information paying unit 134 (to be described later) sends Web session information And communication for providing a service to the terminal 200 by a service providing unit 136 described later. In the first embodiment, it is assumed that any of the above-described communications is performed using HTTP, but in particular, the communication by the service providing unit 136 is “Web communication” in the sense that the communication is related to the Web service. Call.

  The storage unit 120 is a storage device such as a semiconductor memory element or a hard disk that stores information used for various controls in the control unit 130. As shown in FIG. 2, the storage unit 120 includes a temporary registration DB 121, a user management DB 122, and a session information DB 123.

  The temporary registration DB 121 stores the IP address of the user's home terminal acquired from HTTP access by a Web browser or the like before the IP address and the telephone number used by the user home terminal are registered in association with each other. Then, the temporary registration DB 121 deletes the IP address when the stored IP address is associated with the telephone number and stored in the user management DB 122.

  For example, as illustrated in FIG. 3, the temporary registration DB 121 stores “ID, telephone number, IP address, registration protocol, temporary address” in association with each other. “ID” is an identifier for identifying a record, and “telephone number” is a user acquired from SIP communication or the like before the IP address and telephone number used by the terminal at the user's home are registered in association with each other. Stores the telephone number of the home (sender). The “IP address” stores an IP address acquired from HTTP access by a Web browser or the like before the IP address used by the terminal at the user's home and the telephone number are registered in association with each other. “Registration protocol” indicates a protocol for obtaining an IP address or a telephone number. The “temporary address” is an identifier that uniquely identifies the IP address stored in the “IP address”, and may be any information.

  Specifically, the temporary registration DB 121 normally does not store any information as shown in FIG. Then, as illustrated in FIG. 3B, the temporary registration DB 121 generates and acquires a unique ID when an IP address is acquired from access by a Web browser by an IP address association unit 131 described later. Information on the IP address assigned is stored. Thereafter, as shown in FIG. 3C, the temporary registration DB 121 deletes information on the IP address associated with the telephone number by the IP address association unit 131 described later. Note that each piece of information shown in FIG. 3 is merely a specific number for convenience of explanation, and the number does not have any special meaning. FIG. 3 is a diagram illustrating an example of information stored in the temporary registration DB.

  The user management DB 122 stores a correspondence between a telephone number used at a user's house and an IP address. For example, as shown in FIG. 4, the user management DB 122 stores “ID, telephone number, IP address, registration date and time”. “ID” is an identifier for uniquely identifying a record. “Telephone number” is a telephone number used by the user's house, “IP address” is an IP address used by the user's house, and “registration date / time” is registered as a correspondence between the telephone number and the IP address. It was a day.

  Specifically, the user management DB 122 does not store any information as illustrated in FIG. 4A until it is stored in association with the IP address association unit 131 described later. Assume that the IP address associating unit 131 determines that the telephone number of the terminal 200 uses the IP address stored in the temporary registration DB 121. In that case, as shown in FIG. 4B, the user management DB 122 associates the IP address stored in the temporary registration DB 121 with the telephone number, and stores the stored date together. Note that each piece of information shown in FIG. 4 is merely a specific number for convenience of explanation, and the number does not have any special meaning. FIG. 4 is a diagram illustrating an example of information stored in the user management DB.

  The session information DB 123 stores Web session information in association with call session information. Specifically, the session information DB 123 first stores call session information received by a call session information receiving unit 132 (to be described later), and then Web session information paid out by a Web session information issuing unit 134 (to be described later). Is stored in association with the call session information. The session information stored in the session information DB 123 is used for processing by the service providing unit 136 described later.

  Here, call session information and Web session information will be described. Originally, the session information is information that uniquely identifies communication in the fifth layer, which is called OSI (Open Systems Interconnection). That is, in the service providing system according to the first embodiment, it is assumed that SIP communication and Web communication (HTTP communication) are performed as communication, but both SIP communication and Web communication are TCP (Transmission Control). Protocol) communication cannot be identified in the fourth layer. For this reason, by adding session information to the communication established between the terminals, it is identified whether the communication is SIP communication or Web communication. That is, call session information is session information indicating SIP communication, and Web session information is session information indicating Web communication.

  Further, the session information not only identifies SIP communication and Web communication, but also identifies that communication established between terminals is different from communication established between other terminals. In other words, call session information is information that uniquely identifies communication established by SIP between terminals, and Web session information is information that uniquely identifies web communication established between terminals. is there. Call session information includes “Call-ID”, which is information included in SIP communication, “From”, “To”, “tag”, an IP address, or a method using a combination thereof, or SIP communication. A method of using other information included in combination is conceivable, and any method may be used as long as it uses information that can uniquely identify communication established by SIP. On the other hand, as the Web session information, a method using a “session ID” (such as a Cookie ID), which is information given to a browser used when the terminal 200 performs Web communication, can be considered. Note that these call session information and Web session information are generally generated uniquely for each established session, and do not compete in the range of normal application usage.

  Returning to the description of the session information DB 123, the session information DB 123 stores the association between call session information and Web session information, for example, as shown in FIG. That is, when call session information “100” is received from one terminal 200 by a call session information receiving unit 132 to be described later, the session information DB 123 stores the call session information “100” as shown in FIG. Remember. Next, when the Web session information “123” is paid out by the Web session information paying unit 134 to be described later, the session information DB 123 converts the Web session information “123” into the call session information “1” as shown in FIG. 100 ”and store it. Similarly, the session information DB 123 stores the call session information “100” for the other terminal 200 as shown in FIG. 5C, and the Web session information as shown in FIG. “456” is stored in association with the call session information “100”. Thereafter, when association is performed by a service providing unit 136 described later, the session information DB 123 stores the association as shown in FIG. Note that the call session information and Web session information shown in FIG. 5 are merely specific numbers for convenience of explanation, and the numbers have no special meaning. FIG. 5 is a diagram illustrating an example of information stored in the session information DB.

  Further, the session information DB 123 not only stores the call session information “100” and the Web session information “123” in association with each other but also stores the originating IP address “10.0. 10.111 ”and the destination IP address“ 10.0.10.199 ”may be stored in association with each other. Further, the session information DB 123 may also store the IP address “2001: fa: 1001: 2400 :: 1” on the Web communication used by the terminal 200 in association with it.

  The “call session information” stored here is session information indicating SIP communication, and the “Web session information” is session information indicating Web communication. The “originating side IP address” is an IP address used in SIP communication acquired by the IP address associating unit 131 from the originating side SDP (Session Description Protocol) in SIP communication. The “destination IP address” is an IP address used in SIP communication, acquired from the SDP on the callee side in SIP communication by the IP address association unit 131. “Web communication IP address” is an IP address when a terminal using SIP communication uses an IP address stored in “originating IP address” or “destination IP address” for Web communication. The call session information and Web session information shown in FIG. 6 are merely specific numbers for convenience of explanation, and the numbers do not have any special meaning. FIG. 6 is a diagram illustrating an example of information stored in the session information DB.

  Returning to FIG. 2, the control unit 130 is an integrated circuit or an electronic circuit such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The control unit 130 includes an IP address associating unit 131, a call session information receiving unit 132, an authentication executing unit 133, a Web session information paying unit 134, an associating unit 135, and a service providing unit 136.

  The IP address associating unit 131 associates the telephone number used at the user's home with the IP address and stores it in the user management DB 122 as a pre-stage for controlling the service based on the ad hoc changing relationship between the user homes. To do. For example, when receiving an HTTP access from a terminal at the user's home, the IP address association unit 131 acquires an IP address from the access and issues a temporary address to the acquired IP address. The IP address associating unit 131 transmits the temporary address to the access source terminal, and stores the acquired IP address and the issued temporary address in the temporary registration DB 121 in association with each other.

  Thereafter, when the INVITE in SIP communication including the temporary address is received from the terminal of the user's home, the IP address association unit 131 determines whether or not the temporary address is registered in the temporary registration DB 121. Then, when the temporary address is registered in the temporary registration DB 121, the IP address associating unit 131 associates the “IP address” registered in the temporary registration DB 121 with the “telephone number” included in the SIP communication. And stored in the user management DB 122. At this time, the IP address association unit 131 deletes the information in the temporary registration DB 121. The IP address associating unit 131 may further associate and store an IP address included in the SDP or the like of SIP communication, that is, an IP address used on the SIP communication.

  The call session information receiving unit 132 receives call session information. Specifically, the call session information receiving unit 132 acquires call session information by receiving call session information transmitted from the terminal 200 that has established communication by SIP. Further, the call session information receiving unit 132 stores the received call session information in the session information DB 123. Further, when receiving call session information from the terminal 200, the call session information receiving unit 132 also receives an IP address used by the terminal 200. Then, the call session information reception unit 132 transmits the received IP address to the authentication execution unit 133.

  The authentication execution unit 133 performs authentication using the IP address, and when the authentication is permitted, notifies the Web session information issuing unit 134 to that effect. When the authentication is rejected, the authentication execution unit 133 transmits the authentication rejection to the terminal 200. To do. For example, the authentication execution unit 133 permits the authentication when the IP address from which the call session information receiving unit 132 received the call session information and the telephone number included in the call session information are stored in the user management DB 122. If it is not stored in the user management DB 122, authentication is rejected.

  Further, it is assumed that the session information DB 123 stores “call session information” and “Web communication IP address” in association with each other as shown in FIG. In this case, the authentication execution unit 133 may perform authentication based on whether or not the combination of the call session information and the IP address received by the call session information reception unit 132 is stored in the session information DB 123.

  When authentication is permitted by the authentication execution unit 133, the Web session information payout unit 134 pays out Web session information to a terminal that is permitted to be authenticated. Specifically, when the call session information receiving unit 132 receives the call session information, the Web session information paying unit 134 performs Web communication (the terminal for receiving service provision) performed by the terminal 200 that has transmitted the call session information. Web session information is paid out as information to be given to the Web communication 200) 200 performs with the service providing apparatus 100. In addition, the web session information payout unit 134 transmits the paid out web session information to the terminal 200.

  The associating unit 135 stores the Web session information in association with the call session information. Specifically, the associating unit 135 stores the Web session information paid out by the Web session information paying unit 134 in the session information DB 123 in association with the call session information acquired by the call session information receiving unit 132.

  The service providing unit 136 controls the service. Specifically, the service providing unit 136 controls the services provided using each of the Web session information stored in the session information DB 123 in association with each other.

  For example, as shown in (d) and (e) of FIG. 5, the service providing unit 136 includes two pieces of call session information “100” among the plurality of call session information stored in the session information DB 123. It is determined that the same communication is established by SIP. Then, the service providing unit 136 performs the Web communication to which the Web session information “123” stored in association with the call session information “100” is added and the Web communication to which the Web session information “456” is assigned. The services provided and used are controlled in association with each other.

  That is, for example, when the other terminal 200 is accessing the service providing apparatus 100 by Web communication to which the Web session information “456” is assigned, the one terminal 200 is assigned the Web session information “123”. It is assumed that image data is uploaded to the service providing apparatus 100 by Web communication. In such a case, since the relationship between the terminals 200 is a relationship in which the same communication is established by SIP, this relationship is a relationship in which image data sharing is mutually recognized, and the service providing unit according to the first embodiment. 136 controls the service to transmit image data to the other terminal 200.

  Here, the service provision by the service providing apparatus 100 is considered again. That is, the point that service provision by the service providing apparatus 100 is controlled based on the relationship between the terminals 200 is the same as that of the conventional service providing apparatus. It is important how to understand the relationship.

  That is, unlike the conventional service providing apparatus, the service providing apparatus 100 according to the first embodiment does not grasp the relationship registered in the storage unit in advance as the “relationship between each terminal 200”. When each call session information indicates that the same communication has been established by SIP, the “relation between the terminals 200” is grasped. In other words, the service providing apparatus 100 has such a temporary communication relationship even when the relationship with the terminal 200 that is the communication partner is temporary, such as the relationship between the terminals 200 that have established the same communication by SIP. Based on this, it is possible to provide a service associated with a temporary communication relationship by associating Web communication performed in each terminal 200 with each other.

  Note that, as in the first embodiment, when the first communication is communication in the process of establishing communication by SIP, it is also meaningful in that the “relationship between each terminal 200” is an authenticated relationship by SIP. is there. That is, in SIP communication, Digest (digest) authentication is generally performed, and the fact that communication is established between the terminals 200 by SIP means that the relationship between each terminal 200 has been authenticated. Indicates.

Further, the call session information collection unit 213 transmits the collected call session information to the activation instruction unit 214. For example, the call session information collection unit 213 uses “Call-ID”, “From”, “To”, “tag”, IP address, or a combination thereof included in SIP communication as call session information. Collect other information included in SIP communication. The call session information may be any information as long as it is information that can uniquely identify communication established by SIP.

  The activation instructing unit 214 instructs to activate the information display function unit 220. Specifically, when the call session information is transmitted by the call session information collection unit 213, the activation instruction unit 214 instructs to activate the information display function unit 220 (when the information display function unit 220 is activated). In addition, an instruction to activate a call session information transmission unit 223 (to be described later) is transmitted, and a URL (Uniform Resource Locator) and call session information of the service providing apparatus 100 are transmitted to the call session information transmission unit 223.

  The information display function unit 220 is a browser that performs HTTP communication in the terminal 200, and particularly includes an HTTP communication unit 221 and a control unit 222 as shown in FIG. The HTTP communication unit 221 includes a general interface and library for HTTP communication, and transmits / receives information to / from the service providing apparatus 100. Specifically, the HTTP communication unit 221 performs communication in which call session information is transmitted from a call session information transmission unit 223 described later to the service providing apparatus 100, or a Web session information reception unit 224 described later performs a Web session from the service providing apparatus 100. Communication for receiving information, communication for receiving service provision from the service providing apparatus 100 by the service using unit 225 described later, and the like are performed.

  The control unit 222 is an integrated circuit that performs various controls in the information display function unit 220 or an electronic circuit such as a CPU or MPU.

  The call session information transmission unit 223 transmits call session information. Specifically, when the call session information transmission unit 223 receives the URL of the service providing apparatus 100 and the call session information from the activation instruction unit 214, the call session information transmission unit 223 transmits the call session information to the service providing apparatus 100 indicated by the URL. In the first embodiment, since the terminal 200 stores the URL of the service providing apparatus 100 in the storage unit in advance, the call session information transmitting unit 223 transmits the call session information to the service providing apparatus 100 indicated by the URL. Send.

  The web session information receiving unit 224 receives web session information. Specifically, the web session information receiving unit 224 receives web session information from the service providing apparatus 100. Further, the web session information receiving unit 224 transmits the received web session information to the service using unit 225.

  The service using unit 225 receives a service provided by the service providing apparatus 100 and uses the service. Specifically, the service using unit 225 gives the Web session information transmitted by the Web session information receiving unit 224 to a browser that performs HTTP communication, and receives service provision from the service providing apparatus 100. Web communication is performed.

[Process flow]
Next, the processing sequence of the service providing system will be described with reference to FIG. FIG. 8 is a sequence diagram illustrating the flow of processing by the service providing system according to the first embodiment.

(sequence)
As illustrated in FIG. 8, the information display function of the terminal 200 performs Web access to the service providing apparatus 100 (step S101). Subsequently, the IP address associating unit 131 of the service providing apparatus 100 acquires an IP address from the received Web access, pays out a unique temporary address with respect to the acquired IP address, and sets the IP address and the temporary address. Are stored in the temporary registration DB 121 in association with each other (step S102). Thereafter, the IP address associating unit 131 of the service providing apparatus 100 responds with the issued temporary address to the information display function of the access source terminal 200 (step S103).

  Thereafter, the SIP phone function of the terminal 200 receives an input of the temporary address received by the information display function from the user (step S104). Subsequently, the SIP phone function of the terminal 200 transmits a SIP connection request (INVITE) with the service providing apparatus 100 as a connection destination via the SIP proxy 300 (step S105).

  Then, the IP address associating unit 131 of the service providing apparatus 100 acquires an IP address that matches the temporary address included in the INVITE received from the SIP phone function of the terminal 200 from the temporary registration DB 121, and stores the acquired IP address and INVITE. The telephone number (SIP-URI) included is associated and stored in the user management DB 122 (step S106). Thereafter, the IP address associating unit 131 of the service providing apparatus 100 transmits a response (200 OK) to INVITE to the SIP phone function of the terminal 200 (step S107).

  The processes of S101 to S107 described above are executed similarly between the terminal 400 and the service providing apparatus 100 (steps S108 to S114). Therefore, the service providing apparatus 100 can store a pair of a telephone number and an IP address in the user management DB 122 for each of the terminal 200 and the terminal 400. Note that the processing order of the terminal 200 and the terminal 400 may be the same timing or different timings.

  Thereafter, SIP communication in steps S115 to S120 is performed via the SIP proxy 300 between the SIP communication units 211 of the terminal 200 and the terminal 400. As a result, in step S121, the SIP communication between the terminal 200 and the terminal 400 is performed by SIP. Communication is established. Note that Digest authentication, REGISTER processing, and the like in SIP communication are not shown, but are performed before step S115, as in general SIP communication.

  When communication is established between both terminals by SIP, the call session information collection unit 213 of the terminal 200 includes call session information that uniquely identifies communication established with the terminal 400 by SIP in SIP communication. (Step S122). The activation instruction unit 214 of the terminal 200 issues an instruction to activate the information display function unit 220 and transmits the URL and call session information of the service providing apparatus 100 to the call session information transmission unit 223 of the information display function unit 220. (Step S123, Step S124). Then, the call session information transmission unit 223 transmits the call session information to the service providing apparatus 100 indicated by the URL (Step S125).

  Similarly, the call session information collection unit 213 of the terminal 400 collects call session information that uniquely identifies communication established with the terminal 200 by SIP from information included in the SIP communication (step S126). The activation instruction unit 214 of the terminal 400 issues an instruction to activate the information display function unit 220 and transmits the URL and call session information of the service providing apparatus 100 to the call session information transmission unit 223 of the information display function unit 220. (Step S127, Step S128). Then, the call session information transmission unit 223 transmits the call session information to the service providing apparatus 100 indicated by the URL (Step S129). Note that the processing order of the terminal 200 and the terminal 400 may be the same timing or different timings.

  Here, information included in the SIP communication will be described with reference to FIGS. 9 and 10. 9 and 10 are diagrams for explaining the SIP message. FIG. 9 shows a request message, and FIG. 10 shows a response message.

  The SIP message has a part called a start line, a part called a header, and a part called a body. In the example of the request message shown in FIG. 9, the “INVITE” line is the start line, the “Via” line to the “Content-Length” line is the header, and the “v = 0” line to the “a = rtpmap” line : 0 PCMU / 8000 "line is the body. As shown in FIG. 9, the body is described in a format called SDP (Session Description Protocol), in which the IP address of the originator of the SIP message is described.

  For example, the SDP of the request message shown in FIG. 9 describes the IP address “10.0.10.111” of the SIP phone that has transmitted the request message. Similarly, the SDP of the response message shown in FIG. 10 describes the IP address “10.0.10.199” of the SIP phone that has transmitted the response message. Thus, the SIP message includes the IP address of the SIP message source.

  Returning to FIG. 8, the authentication execution unit 133 of the service providing apparatus 100 determines whether or not the IP address used by the terminal 200 for Web access is stored in the user management DB 122, and the IP address used by the terminal 400 for Web access. Is authenticated by the IP address for authenticating whether or not is stored in the user management DB 122 (step S130).

  When the call session information receiving unit 132 of the service providing apparatus 100 receives the call session information transmitted from the terminal 200, subsequently, the Web session information issuing unit 134 performs the Web communication performed by the terminal 200 that has transmitted the call session information. As information to be given to (Web communication performed by the terminal 200 with the service providing apparatus 100 to receive service provision), Web session information is paid out (step S131), and the paid-out Web session information is transmitted to the terminal 200 ( Step S132). Similarly, the web session information payout unit 134 pays out web session information to the terminal 400 (step S133).

  Next, the associating unit 135 of the service providing apparatus 100 uses the Web session information paid out for the terminal 200 in steps S131 and S133, the call session information acquired for the terminal 200 in step S125, and the terminal 400 in step S129. It is stored in the session information DB 123 in association with the acquired call session information (step S134).

  The service providing unit 136 of the service providing apparatus 100 confirms that each of predetermined call session information among the plurality of call session information stored in the session information DB 123 is established as the same communication by SIP. In the case shown, the services provided by using the Web session information stored in association with the call session information are controlled in association with each other (steps S135 to S138).

  “Matching” shown in FIG. 8 means that the service providing unit 136 determines whether or not each call session information is established as the same communication by SIP. In addition, the service providing unit 136 associates the Web session information given to the Web communication of each of the terminal 200 and the terminal 400 with each other, so that the same communication is established for each of the Web communication of the terminal 200 and the terminal 400 by SIP. It is treated as a relationship.

  In this way, the service providing unit 136 of the service providing apparatus 100 controls the service based on the association performed in step S134.

  That is, for example, the service using unit 225 of the terminal 200 uploads image data to the service providing apparatus 100 through Web communication to which the Web session information paid out in Step S132 is added (Step S135), and the service of the terminal 400 It is assumed that the use unit 225 is accessing the service providing apparatus 100 through Web communication to which Web session information paid out from the service providing apparatus 100 is assigned (step S136). Then, the service providing unit 136 controls the service so that the image data is transmitted to the terminal 400, so that the image data is transmitted to the terminal 400 (step S137), and the information display function unit of the terminal 400 is sent to the output unit 202. The image data is displayed (step S138).

(Authentication by IP address)
Next, an authentication process using an IP address corresponding to step S130 shown in FIG. 8 will be described with reference to FIG. FIG. 11 is a flowchart showing an authentication process using an IP address.

  As illustrated in FIG. 11, when the call session information receiving unit 132 receives the IP address of the terminal 200 (Yes in step S201), the authentication execution unit 133 of the service providing apparatus 100 receives the received IP address as the user management DB 122. It is determined whether or not it matches the IP address stored in (step S202). That is, the authentication execution unit 133 acquires an IP address from the Web access that has received the call session information in step S125 of FIG. 8, and the combination of the acquired IP address and the telephone number included in the call session information is stored in the user management DB 122. It is determined whether or not it is stored. That is, the authentication execution unit 133 determines whether or not the combination of the acquired IP address and the telephone number included in the call session information is information registered in advance.

  If the acquired IP address and telephone number are stored in the user management DB 122 (Yes at Step S202), the authentication execution unit 133 permits authentication and pays out to the terminal 200 that has permitted Web session information (Step S202). S203).

  On the other hand, if the acquired IP address and telephone number are not stored in the user management DB 122 (No at Step S202), the authentication execution unit 133 rejects the authentication and transmits an authentication error to the terminal 200 (Step S204). .

  Further, the method of authenticating by the authentication execution unit 133 is not limited to this. For example, the authentication execution unit 133 determines whether or not the set of the call session information itself received by the call session information reception unit 132 and the IP address acquired from the Web access that received the call session information is stored in the session information DB 123. You may authenticate. Further, the authentication execution unit 133 may perform authentication based on whether or not the IP address acquired from the Web access that has received the call session information is stored in the session information DB 123.

[Effects of Example 1]
As described above, according to the first embodiment, as a pre-process for controlling a service based on a temporary communication relationship, an association between an IP address and a telephone number that are actually used can be registered. As a result, when the service is controlled based on the temporary communication relationship, it is possible to perform the authentication by the IP address regardless of the performance of the terminal using the service or the IP address system.

  An IP address used in Web communication and a telephone number, IP address, etc. used in SIP communication can be stored in advance in association with each other. As a result, even when the IP address used in SIP communication is in IPv4 notation and the IP address used in Web communication is in IPv6 notation, authentication by the IP address can be performed. Further, it is not necessary to incorporate a special function such as a stack for processing the SIP into the information display function of the terminal 200 or the like, and it is possible to perform authentication using the IP address.

  By the way, the service providing system disclosed in the present application may be configured using an HGW. Specifically, the HGW 500 may be provided between the SIP proxy 300 and the terminal 200, and the HGW 600 may be provided between the SIP proxy 300 and the terminal 400. Furthermore, the terminal 200 and the terminal 400 may be realized by separate housings such as the SIP phone 250 and the information display terminal 260.

  Therefore, in the second embodiment, a service providing system will be described in which the HGW 500 and the HGW 600 are provided, and the terminal 200 and the terminal 400 are realized in separate housings such as the SIP phone 250 and the information display terminal 260.

Terminal ID) and browser session information for specifying the information display terminal 260 are stored in advance in association with each other. Further, the information stored in the browser session information DB 521 is used for processing by the information display terminal specifying unit 533 described later. As a situation where the SIP phone and the information display terminal are “used in a pair”, for example, a case where the SIP phone and the information display terminal are used by the same user is assumed.

  Here, the SIP phone ID is, for example, an extension number of the SIP phone. In the case of a configuration in which a plurality of SIP phones are connected under the HGW (a configuration in which a plurality of SIP phones communicate simultaneously), the SIP-URI is given to the HGW, and each SIP phone under the HGW has an extension number. Is granted. That is, when a SIP phone under the HGW is designated as a communication partner, a combination of the HGW's SIP-URI and extension number must be designated.

  Returning to the description of the browser session information DB 521, the browser session information DB 521 stores a correspondence between the SIP phone ID, the information display terminal ID, and the browser session information, for example, as shown in FIG. Note that the SIP phone ID, information display terminal ID, and browser session information shown in FIG. 13 are merely specific numbers for convenience of explanation, and the numbers do not have any special meaning.

  The call session information collection unit 531 collects call session information. Specifically, the call session information collection unit 531 includes call session information that uniquely identifies communication established by SIP between the subordinate SIP phone 250 and the other SIP phone 250 as information included in the SIP communication. Collect from. Further, the call session information collection unit 531 transmits the collected call session information to the information display terminal identification unit 533.

  The SIP phone ID collection unit 532 collects the SIP phone ID. Specifically, the SIP phone ID collection unit 532 collects the SIP phone ID, which is information for uniquely identifying the subordinate SIP phone 250, from information included in the SIP communication. In addition, the SIP phone ID collection unit 532 transmits the collected SIP phone ID to the information display terminal identification unit 533.

  The information display terminal specifying unit 533 specifies the information display terminal 260 used in combination with the SIP phone 250 that has established communication by SIP. Specifically, the information display terminal specifying unit 533 searches the browser session information DB 521 using the SIP phone ID collected by the SIP phone ID collection unit 532 as a search key, and is uniquely identified by the SIP phone ID. The information display terminal 260 used in combination with the phone 250 is specified, and the browser session information of the information display terminal 260 is specified. Next, the information display terminal specifying unit 533 compares the specified browser session information with the browser session information of each of the plurality of information display terminals 260 that poll the HGW 500, and performs polling that matches the browser session information. The information display terminal 260 is identified as the information display terminal 260 used in combination with the SIP phone 250 that has established communication by SIP. Then, the information display terminal identification unit 533 transmits the identification information of the information display terminal 260 and the call session information to the access destination change instruction unit 534.

  The access destination change instruction unit 534 issues an access destination change instruction to the information display terminal 260. Specifically, when the information display terminal specifying unit 533 transmits the specific information of the information display terminal 260 and the call session information from the information display terminal specifying unit 533, the access destination change instruction unit 534 sends the information to the information display terminal 260 specified by the specific information. Then, a redirect instruction for instructing the URL of the service providing apparatus 100 to change the access destination is performed together with the call session information.

The HTTP communication unit 264 includes a general interface and library for HTTP communication, and transmits / receives information to / from the service providing apparatus 100 (via the HGW 500).

  The control unit 265 is an integrated circuit that performs various controls in the information display terminal 260 or an electronic circuit such as a CPU or MPU. As shown in FIG. 12, a call session information transmission unit 266, a Web session information reception unit 267, A service using unit 268.

  The call session information transmission unit 266 transmits call session information. Specifically, when redirected by the access destination change instruction unit 534 of the HGW 500, the call session information transmission unit 266 changes the access destination to the service providing apparatus 100 and transmits call session information to the service providing apparatus 100. At this time, since the call session information transmission unit 266 accesses the service providing apparatus 100 by a browser that performs HTTP communication, the Web session information of the information display terminal 260 is given to the HTTP communication.

  The web session information receiving unit 267 receives web session information. Specifically, the web session information receiving unit 267 receives web session information from the service providing apparatus 100. Further, the web session information receiving unit 267 transmits the received web session information to the service using unit 268.

  The service using unit 268 receives the service provided by the service providing apparatus 100 and uses the service. Specifically, the service using unit 268 gives the Web session information transmitted by the Web session information receiving unit 267 to a browser that performs HTTP communication, and receives service provision between the service providing unit 100 and the service providing apparatus 100. Web communication is performed.

(Process flow)
Next, the flow of processing in the service providing apparatus will be described with reference to FIG. FIG. 14 is a sequence diagram illustrating the flow of processing in the service providing apparatus according to the second embodiment.

  As illustrated in FIG. 14, the HTTP communication unit 264 of the information display terminal 260 receives a user instruction operation via the input unit 261 and performs Web access to the service providing apparatus 100 (step S301).

  The IP address associating unit 131 of the service providing apparatus 100 that has received the Web access from the information display terminal 260 acquires the IP address from the Web access, issues a temporary address associated with the acquired Web access, and issues the acquired IP address and payout The temporary addresses are associated with each other and stored in the temporary registration DB 121 (step S302). That is, the IP address associating unit 131 recognizes the acquired IP address as an IP address used by the user on the Web. Subsequently, the IP address associating unit 131 transmits a response including the issued temporary address to the access source information display terminal 260 (step S303).

  After that, when receiving a temporary address from the user via the input unit 251, the SIP communication unit 254 of the SIP phone 250 transmits an INVITE of SIP communication including the temporary address to the HGW 500 with the service providing apparatus 100 as a destination ( Step S304). The HGW 500 transmits the received INVITE to the SIP proxy 300 (step S305), and the SIP proxy 300 transfers the INVITE to the destination service providing apparatus 100 (step S306).

  Then, the IP address associating unit 131 of the service providing apparatus 100 acquires the IP address corresponding to the temporary address included in the received SIP INVITE from the temporary registration DB 121, and uses the acquired IP address as the telephone number included in the INVITE. The data are stored in the user management DB 122 in association with each other (step S307). Thereafter, the IP address association unit 131 transmits a response (200 OK) destined for the SIP phone 250 to the SIP proxy 300 (step S308), and the SIP proxy 300 transmits the received response to the HGW 500 (step S309). ). Then, the HGW 500 transfers the response transmitted from the service providing apparatus 100 to the SIP phone 250 (step S310).

  The processes of S301 to S310 described above are executed similarly between the HGW 600 and the service providing apparatus 100 (steps S311 to S320). Therefore, the service providing apparatus 100 can store a pair of a telephone number and an IP address in the user management DB 122 for both terminals. Note that the processing order may be the same timing or different timings.

  Thereafter, SIP communication in steps S321 to S328 is performed between the SIP phone 250 and the SIP phone 450 via the HGW 500, the HGW 600, and the SIP proxy 300. As a result, in step S329, the SIP phone 250 and the SIP phone 450 are processed. Communication is established with SIP. Note that Digest authentication, REGISTER processing, and the like in SIP communication are not shown, but are performed prior to step S321 as in general SIP communication.

  When communication is established between both SIP phones by SIP, the call session information collection unit 531 of the HGW 500 uniquely identifies the communication established by SIP between the subordinate SIP phone 250 and the other SIP phone 450. Call session information is collected from information included in the SIP communication (step S330), and is transmitted to the information display terminal specifying unit 533 in step S332.

  Next, the SIP phone ID collection unit 532 of the HGW 500 collects the SIP phone ID, which is information for uniquely identifying the subordinate SIP phone 250, from the information included in the SIP communication (step S331), and specifies the information display terminal. This is transmitted to the unit 533 (step S332).

  Subsequently, the information display terminal specifying unit 533 of the HGW 500 specifies the information display terminal 260 used in combination with the SIP phone 250 with which communication is established in step S329 (step S333). Specifically, the information display terminal specifying unit 533 first specifies the information display terminal 260 by searching the browser session information DB 521 using the SIP phone ID as a search key, and the browser session information of the specified information display terminal 260 and The browser session information of each of the plurality of information display terminals 260 that performs polling (step S334) with respect to the HGW 500 is compared, and the information display terminal 260 used in combination with the SIP phone 250 that has established communication by SIP is specified. .

  Then, the access destination change instruction unit 534 of the HGW 500 issues an access destination change instruction to the information display terminal 260 specified in step S333. Specifically, a redirect instruction that instructs the specified information display terminal 260 to change the access destination to the URL of the service providing apparatus 100 is performed together with the call session information (step S335). In the second embodiment, the HGW 500 stores the URL of the service providing apparatus 100 in the storage unit in advance, so that the access destination change instruction unit 534 changes the access destination to the URL for the information display terminal 260. A redirection instruction can be issued to instruct.

  Then, the call session information transmission unit 266 of the information display terminal 260 is redirected, changes the access destination to the service providing apparatus 100, and transmits call session information to the service providing apparatus 100 (step S335).

  In addition, the process of step S330-step S335 mentioned above is performed similarly between the information display terminal 260 and the service provision apparatus 100 (step S336-step S341). Note that the processing order of the information display terminal 260 and the information display terminal 460 may be the same timing or different timings.

  Thereafter, the processing (steps S342 to S350) from when the service providing apparatus 100 authenticates with the IP address, pays out the web session information, and controls the service based on the web session information (steps S342 to S350) is the step described in the first embodiment. Since it is the same as S130-step S138, it abbreviate | omits here.

(Effects of Example 2)
As described above, according to the second embodiment, the terminal is configured with a plurality of SIP phones and a plurality of information display terminals, and the service is used even when the relationship with the communication partner is temporary. Regardless of the performance of the terminal and the IP address system, it is possible to perform authentication based on the IP address, and it is possible to realize service provision based on such a temporary communication relationship.

  By the way, the service providing apparatus 100 according to the first and second embodiments first acquires an IP address from HTTP access and issues a temporary address, and then acquires a telephone number from SIP communication including the issued temporary address, An example in which these are stored in association with each other has been described. The present application is not limited to this.

  For example, the service providing apparatus 100 first acquires a telephone number and an IP address from SIP communication, and then acquires an IP address from HTTP access. Then, the service providing apparatus 100 may rewrite and associate the IP address acquired from the SIP communication associated with the telephone number with the IP address acquired from the HTTP access.

  Accordingly, in the third embodiment, an example in which the service providing apparatus 100 rewrites and associates the IP address acquired from the SIP communication associated with the telephone number with the IP address acquired from the HTTP access will be described with reference to FIG. To do. FIG. 15 is a sequence diagram illustrating the flow of processing in the service providing system according to the third embodiment.

  As illustrated in FIG. 15, the SIP phone function unit 210 of the terminal 200 transmits the SIP INVITE to the service providing apparatus 100 via the SIP proxy 300 (steps S401 and S402). Subsequently, the service providing apparatus 100 transmits a response (200 OK) to INVITE to the SIP phone function unit 210 of the terminal 200 via the SIP proxy 300 (steps S403 and S404). As a result, the service providing apparatus 100 and the SIP phone function unit 210 of the terminal 200 are connected by voice (step S405).

  Similarly, the SIP phone function unit of the terminal 400 transmits the SIP INVITE to the service providing apparatus 100 via the SIP proxy 300 (steps S406 and S407). Subsequently, the service providing apparatus 100 transmits a response (200 OK) to INVITE to the SIP phone function unit of the terminal 400 via the SIP proxy 300 (steps S408 and S409). As a result, the service providing apparatus 100 and the SIP phone function unit of the terminal 400 are connected by voice (step S410).

  Thereafter, the IP address associating unit 131 of the service providing apparatus 100 stores the telephone number and call session information acquired in Steps S401 to S402 in the temporary registration DB 121 (Step S411). Similarly, the IP address associating unit 131 of the service providing apparatus 100 stores the telephone number and call session information acquired in Steps S406 to S407 in the temporary registration DB 121 (Step S411). That is, the IP address associating unit 131 of the service providing apparatus 100 stores the telephone number of the terminal 200 and call session information in association with each other, and stores the telephone number of the terminal 400 in association with call session information.

  Thereafter, the SIP phone function unit 210 of the terminal 200 collects call session information (step S412), and transmits the collected call session information to the information display function unit 220 (step S413). Then, the information display function unit 220 performs Web access including call session information on the service providing apparatus 100 (step S414).

  Similarly, the SIP phone function unit of terminal 400 collects call session information (step S415), and transmits the collected call session information to the information display function unit (step S416). Then, the information display function unit performs Web access including call session information on the service providing apparatus 100 (step S417).

  Then, the IP address associating unit 131 of the service providing apparatus 100 acquires the telephone number associated with the call session information included in the Web access received in Step S414 from the temporary registration DB 121 and obtains the IP address from the Web access. The telephone numbers and the IP addresses are associated with each other and stored in the user management DB 122 (step S418). Further, the SIP communication between the terminal 200 and the service providing apparatus 100 may be connected by the terminal 200, and the SIP communication between the terminal 400 and the service providing apparatus 100 may be disconnected by the operation of the terminal 400. Good. If not disconnected, the terminal 200 or the terminal 400 connects a plurality of SIP communications (voice communications).

  Similarly, the IP address associating unit 131 of the service providing apparatus 100 acquires the telephone number associated with the call session information included in the web access received in step S417 from the temporary registration DB 121, and also obtains the IP address from the web access. And the telephone number and the IP address are associated with each other and stored in the user management DB 122 (step S418).

  The subsequent processing from step S419 to step S442 is the same as step S115 to step S138 described in the first embodiment, and is omitted here.

  As described above, according to the third embodiment, when the association between the telephone number and the IP address is stored, whichever information is provisionally registered first, the telephone number used by the terminal and the terminal is the Web Can be stored in association with the IP address used in the.

  By the way, in the third embodiment, SIP communication is generated before the SIP connection between the terminals, and the telephone number used by the terminal in SIP and the IP address used by the terminal in the Web are associated with each other. I remembered it. However, the present application is not limited to this, and a telephone number and an IP address can be stored in association with each other using a SIP connection between terminals.

  Therefore, in the fourth embodiment, an example in which a telephone number and an IP address are stored in association with each other in a SIP connection between terminals will be described with reference to FIG. FIG. 16 is a sequence diagram illustrating the flow of processing in the service providing system according to the fourth embodiment.

  As illustrated in FIG. 16, SIP communication in steps S501 to S506 is performed via the SIP proxy 300 between the SIP communication units 211 of the terminal 200 and the terminal 400. As a result, in step S508, the terminal 200 and the terminal 200 are connected. Communication is established between the 400 by SIP. Note that Digest authentication, REGISTER processing, and the like in SIP communication are not shown, but are performed before step S501 as in general SIP communication.

  When the SIP communication is connected between the terminals, the IP address associating unit 131 of the service providing apparatus 100 acquires a set of the telephone number and the IP address used by the terminal 200 in the SIP communication from the SIP proxy 300. And stored in the temporary registration DB 121 (step S509).

  Similarly, when SIP communication is connected between terminals, the IP address associating unit 131 of the service providing apparatus 100 sets a pair of a telephone number and an IP address used by the terminal 400 in the SIP communication from the SIP proxy 300. It is acquired and stored in the temporary registration DB 121 (step S509).

  Thereafter, the SIP phone function unit 210 of the terminal 200 collects call session information (step S510), and transmits the collected call session information to the information display function unit 220 (step S511). Then, the information display function unit 220 performs Web access including call session information on the service providing apparatus 100 (step S512).

  Similarly, the SIP phone function unit of terminal 400 collects call session information (step S513), and transmits the collected call session information to the information display function unit (step S514). Then, the information display function unit performs Web access including call session information on the service providing apparatus 100 (step S515).

  Then, the IP address associating unit 131 of the service providing apparatus 100 acquires the telephone number associated with the call session information included in the web access received in step S512 from the temporary registration DB 121, and also obtains the IP address from the web access. The telephone numbers and the IP addresses are associated with each other and stored in the user management DB 122 (step S516).

  Similarly, the IP address associating unit 131 of the service providing apparatus 100 acquires the telephone number associated with the call session information included in the web access received in step S522 from the temporary registration DB 121, and also obtains the IP address from the web access. And the telephone number and the IP address are associated with each other and stored in the user management DB 122 (step S523).

  The subsequent processing from step S517 to step S531 is the same as that in the first embodiment, and is omitted here.

  As described above, according to the fourth embodiment, in the SIP connection between the terminals, the telephone number and the IP address can be stored in association with each other, so that the SIP communication is omitted as compared with the first to third embodiments. Network congestion can also be prevented.

  Although the embodiments of the present invention have been described so far, the present invention may be implemented in various different forms other than the embodiments described above.

(IP address notation)
In the first embodiment, the case where the IP address used in SIP communication is in IPv4 notation and the IP address used in Web communication is in IPv6 notation is described, but the present invention is not limited to this, and vice versa. May be. Moreover, the same notation may be used, and in that case, it can be realized without using a temporary address.

(Select communication protocol)
In the above-described embodiment, the first communication is communication in the process of establishing a session by SIP (Note that the first communication to be disconnected in Embodiment 3 means communication established by SIP) It is assumed that the second communication is Web communication (HTTP communication), but the present invention is not limited to this. As long as the session established by the first communication and the second communication session are different from each other, any specific communication protocol may be used.

(Valid condition)
For example, the service providing apparatus may store the valid condition when acquiring the IP address from the access received from the information display function of the terminal and storing it in the temporary registration DB. Then, the service providing apparatus stores the correspondence between the telephone number and the IP address on condition that the validity condition is satisfied. For example, as shown in FIG. 17, the service providing apparatus stores valid conditions such as the same prefix for 10 minutes after registration during a call. FIG. 17 is a diagram illustrating an example of valid conditions for storing the association between IP addresses and telephone numbers.

(Call session information)
In the above-described embodiment, the call session information acquired by the service providing apparatus from both terminals or both information display terminals has been described as having the same value, but may not have the same value. . A combination of two values may be used as long as the service providing apparatus can recognize the same communication established between terminals by SIP uniquely.

(Collect call session information)
The service providing apparatus may obtain the first communication information collected by the first communication control apparatus that controls the first communication by receiving the first communication information from the first communication control apparatus. In this case, for example, it is possible to control service provision based on a temporary communication relationship by a technique in which the SIP proxy collects the first communication information.

(Reuse of call session information)
In addition, when a service is provided using Web session information, the service providing apparatus obtains information about the provided service and call session information stored in the session information DB in association with the Web session information. The association is stored in the storage unit together with a preset effective period. In addition, when the terminal performs call communication with the service providing apparatus by specifying the call session information stored in the storage unit within the valid period, the service providing apparatus uses the call session information as a search key. The storage unit is searched, and information related to the service stored in association with the call session information is acquired. And the service provision apparatus will control the service with respect to the said terminal based on the said information, if the information regarding a service is acquired. In this case, if it is within the effective period, it becomes possible to control the service based on the temporary communication relationship (past communication relationship) of each terminal that has established the same communication by SIP in the past.

  For example, the terminal stores call session information used at the time of the first use of the Web service in the terminal, while the service providing apparatus associates with the call session information when and with whom and at what timing. It is assumed that the terminal has been stored, the terminal usage data is stored, and the like. Then, when the terminal accesses the service providing apparatus using the call session information at the next use, the service providing apparatus can re-control service provision based on the information.

  Further, a specific example of a service will be described. When an image transmitted to a communication partner is stored in the service providing apparatus, the service user transmits call session information at the time of transmitting the image to the service providing apparatus. Thus, the transmitted image or the received image can be confirmed again. At this time, it is not necessary to be in a call with the communication partner. That is, it can be realized only by the browser sending the call session information to the service providing apparatus regardless of the call.

(System configuration etc.)
In the above embodiment, a case where a single SIP proxy mediates a SIP signal (including SIP specific signals, types such as INVITE and 200 OK, and parameters such as From and To) is described. However, the present invention is not limited to this. The present invention can be similarly applied to a case where a plurality of SIP proxies mediate a SIP signal and a case where an AS (Application Server) in NGN (Next Generation Network) mediates a SIP signal.

  In the above embodiment, the HGW acts as a device that performs information transmission between the SIP phone and the information display terminal and identifies the information display terminal that is the target of service provision. Although described, the present invention is not limited to this. For example, if a SIP phone has a function equivalent to a Web server, information can be transmitted between the SIP phone and the information display terminal, and call session information acquisition processing is performed from the information display terminal to the SIP phone. Thus, it becomes possible to specify the information display terminal that is the target of service provision (the configuration does not require an HGW).

  For example, in the second embodiment, the terminal-side form is divided into a SIP phone and an information display terminal, but it is assumed that the SIP phone has a function equivalent to a Web server. In such a case, both SIP phones collect call session information from the communication established by SIP, and the information display terminal polls the SIP session phone with a function equivalent to a Web server, for example. Acquired from the phone, and accesses the service providing apparatus together with the acquired call session information. Then, the service providing apparatus can acquire call session information.

  In addition, for example, a method of collecting call session information for only one SIP phone is also conceivable. That is, one SIP phone (having a function equivalent to a Web server) collects call session information from communication established by IP, and, similarly to the above, the information display terminal is a SIP phone having a function equivalent to a Web server. The call session information is acquired from the SIP phone by polling, and the service providing apparatus is accessed together with the acquired call session information. Then, the service providing apparatus can first acquire call session information for one. At this time, this SIP phone notifies the collected call session information to the other SIP phone (the SIP phone of the communication partner that has established communication by SIP). Then, the information display terminal used in combination with the other SIP phone acquires call session information by polling the other SIP phone, and accesses the service providing apparatus together with the acquired call session information. Then, the service providing apparatus can acquire call session information for the other.

  In the second embodiment, if the SIP phone has a function equivalent to a Web server, a method in which the SIP PROXY notifies the URL of the service providing device to the SIP phone itself can be used.

  Further, among the processes described in the present embodiment, all or part of the processes described as being automatically performed can be manually performed, or the processes described as being manually performed ( For example, all or part of the process of inputting a temporary address to a SIP phone or the like can be automatically performed by a known method. In addition, the processing procedure, control procedure, specific name, and information including various data and parameters shown in the above-described document and drawings can be arbitrarily changed unless otherwise specified.

  Further, each component of each illustrated apparatus is functionally conceptual, and does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each device is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed or arbitrarily distributed in arbitrary units according to various loads or usage conditions. Can be integrated and configured. Further, all or any part of each processing function performed in each device may be realized by a CPU and a program analyzed and executed by the CPU, or may be realized as hardware by wired logic.

  The service providing method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program can be distributed via a network such as the Internet. The program can also be executed by being recorded on a computer-readable recording medium such as a hard disk, a flexible disk (FD), a CD-ROM, an MO, and a DVD and being read from the recording medium by the computer.

  As described above, the service providing system, the service providing method, and the service providing program according to the present invention are useful for a service providing apparatus that provides a service on the network to a plurality of terminals connected to the network to control the service. In particular, it is suitable for providing a service based on a temporary communication relationship regardless of the performance of the terminal using the service and the IP address system.
