  Exemplary embodiments of a service providing system and a service providing method according to the present invention will be described below in detail with reference to the accompanying drawings. In the following, the main terms used in the embodiment, the outline of the service providing system according to the first embodiment, the configuration of the service providing system according to the first embodiment, the processing procedure by the service providing system according to the first embodiment, the embodiment The effect of 1 will be described in order, and then another embodiment will be described.

[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 server” controls a service, and a “terminal” connected to the network is provided with a “service”.

  By the way, the “service providing server” controls services based on the relationship between each terminal, the relationship between the terminal and the service providing server, 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 server” while terminal B is accessing “service providing server”. In such a case, the “service providing server” 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 server” accepts an input of a user ID and a password from a user of the terminal A, and accepts an input of a user ID and a password from a user of the terminal B, for example. 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 permitted, the “service providing server” 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 server” 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. That is, the “service providing server” has a relationship between the user of the specified terminal A and the user of the specified terminal B, and the relationship that the user of the terminal A is permitted to browse the site by the user of the terminal A 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.

  Also, for example, a case where a “service providing server” that provides music information permits the user of the terminal A to download music information is assumed. In such a case, the “service providing server” controls the download communication by the terminal A based on the relationship between the user of the terminal A and the “service providing server”. That is, the “service providing server” indicates that the relationship between the identified user of the terminal A and the “service providing server” is such that download communication by the user of the terminal A is permitted by the “service providing server”. 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 server, or the relationship between users using the terminal has various modes depending on the service content. The “server” 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 server” 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 server” in the present invention is not only a relationship such as a pre-registered buddy list, but also when the relationship with a 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 Providing System According to Embodiment 1]
As shown in FIG. 1, this service providing system includes user homes A to C having HGWs, information display terminals, SIP phones, etc., SIP proxies, session management servers, service providing servers, 3PCC servers, The conference room server is connected to be able to communicate with each other via a network.

  Briefly explaining the function of each device, the HGW at the user's house is a home gateway that relays communication with other devices and networks, and the information display terminal is on the network using a Web browser or the like. It is a device such as a personal computer that uses a service, and a SIP phone is a device that performs voice connection using SIP, may be realized by hardware, and is realized as software embedded in a personal computer or the like. Also good.

  The SIP proxy is one of the roles of the SIP server, and is a server that transfers a request from a SIP phone or the like to another SIP terminal or SIP server. The session management server is a server that connects user home A, user home B, and user home C using call session information and control session information described later. As described above, the service providing server controls the service based on the relationship between each terminal, the relationship between the terminal and the service providing server, or the relationship between users who use the terminal.

  The 3PCC server is a server that performs “3rd Party Call Control” in which a terminal and a terminal are operated and connected from a third device. The conference room server includes N parties such as a two-party voice bridge and a three-party voice bridge. It is a server that controls connection between voice bridges.

  According to the service providing system having such a configuration, when the relationship with the communication partner is temporary (in the case of a relationship that changes to ad hoc), the service is controlled based on such a temporary communication relationship. Is possible. For example, a plurality of user homes (information display terminals) can be connected to each other by a temporary communication relationship using a simple interface called a SIP phone.

[Configuration of Service Providing System According to Embodiment 1]
Next, the configuration of each device of the service providing system according to the first embodiment will be described with reference to FIGS. In the following, the configuration of the service providing system will be briefly described, and the processing of each unit will be described in detail in the processing procedure described later.

(Configuration of session management server)
FIG. 2 is a block diagram showing the configuration of the session management server. As shown in FIG. 2, the session management server 100 is realized by providing each unit described below in a general-purpose server or the like, and includes a communication control I / F unit 110, a storage unit 120, a control unit 130, and the like. Is provided.

  The communication control I / F unit 110 includes a general interface and library for HTTP communication, and transmits / receives information to / from the information display terminal 20 and transmits / receives information to / from the HGW 10 and the service providing server 200. And so on.

  The storage unit 120 stores information used for various controls in the control unit 130, and particularly as closely related to the present invention, as shown in FIG. 2, a user contract service management table 121 and a contract service information table 122 are stored. And a session management table 123 for control, an arrival / departure linking ID table 124, a conference room service table 125, a conference room correspondence management table 126, and a data table 127.

  The user contract service management table 121 is a table for managing a service contracted by a user (user) who uses the information display terminal 20 (and the SIP phone 30). For example, as shown in FIG. 3, the user contract service management table 121 stores user identification information and a contract service ID in association with each other. These pieces of information stored in the user contract service management table 121 are registered in advance in the service providing system according to the first embodiment, and are appropriately registered.

  Here, the user identification information is information for identifying the user of the information display terminal 20, and SIP-URI (Uniform Resource Identifier) is used in the first embodiment. The contract service ID (hereinafter also referred to as service ID as appropriate) is an ID for identifying a service. As described above, the user contract service management table 121 stores the user identification information and the contract service ID in association with each other so that the user identified by the user identification information can be subscribed to the service identified by the contract service ID. I manage to be a person.

  The contract service information table 122 is a table for managing various information for each contract service. For example, the contract service information table 122 stores the contract service ID and the access destination URL in association with each other as shown in FIG. Here, the access destination URL is the URL of the service providing server 200 that provides the service identified by the contract service ID. These pieces of information stored in the contract service information table 122 are registered in advance and appropriately registered in the service providing system according to the first embodiment.

  The control session management table 123 manages control session information (information given to the Web browser of the information display terminal 20 so that the session management server 100 communicates with the information display terminal 20). It is a table. For example, as shown in FIG. 5, the control session management table 123 includes control session information, Call-ID, From, To, an arrival / departure determination flag, call information (start time to end time), The HGW URL and the group ID are stored in association with each other.

  Among these pieces of information stored in the control session management table 123, the control session information is paid out when the session management server 100 receives a service start request from the information display terminal 20, for example, a session management server 100 is information to be given to the Web browser of the information display terminal 20 in order to communicate with the information display terminal 20, and is established between the information display terminal 20 and the session management server 100. This information uniquely identifies the web communication. When a call session information collection unit 131 described later receives a service start request from the information display terminal 20, the call session information collection unit 131 pays out control session information and stores it in the control session management table 123. As the control session information, a method using a “session ID” (such as a cookie ID) that is information given to a browser used when the information display terminal 20 performs Web communication is conceivable. Further, the control session information is generally generated uniquely for each established session.

  Call session information is information that uniquely identifies a session established by SIP between SIP phones 30. When a call session information collection unit 131 to be described later receives a service start request from the information display terminal 20, the call session information collection unit 131 acquires the call session information collection unit 131 from the information display terminal 20 and stores it in the control session management table 123. As call session information, “Call-ID” or “isub”, which is information included in SIP communication, “From”, “To”, “tag”, an IP address, or a combination thereof is used. A method or a method using a combination of other information (for example, “Date”) included in SIP communication is conceivable, and a method using information that can uniquely identify communication established by SIP is used. Any method may be used. Call session information is generally generated uniquely for each established session.

  In addition, the arrival / departure determination flag refers to the SIP phone 30 (the SIP phone 30 used in combination with the information display terminal 20 that has issued the control session information) for the session established by SIP between the SIP phones 30 on the calling side. It is a flag for determining whether there is a callee or a callee. When a call session information collection unit 131 to be described later receives a service start request from the information display terminal 20, the call session information collection unit 131 acquires the call session information collection unit 131 from the information display terminal 20 and stores it in the control session management table 123.

  Call information is information indicating the start time and end time of a session uniquely identified by call session information. For example, when a call session information collection unit 131 to be described later receives a service start request from the information display terminal 20, the call session information collection unit 131 stores the time in the control session management table 123 as the start time. Note that the call session information collection unit 131 described later may acquire the start time from the information display terminal 20 and store it in the control session management table 123. For example, when the session management server 100 recognizes that the session has been disconnected, the session management server 100 stores the time in the control session management table 123 as the end time.

  The HGW URL is the URL of the HGW 10 that controls HTTP communication by the information display terminal 20. When a call session information collection unit 131 to be described later receives a service start request from the information display terminal 20, the call session information collection unit 131 acquires the call session information collection unit 131 from the information display terminal 20 and stores it in the control session management table 123. The group ID is information for grouping terminals that are connected by telephone (voice bridge).

  As described above, the control session management table 123 is established by the SIP phone 30 (the SIP phone 30 used in combination with the information display terminal 20) in association with the control session information issued by the session management server 100. By storing information relating to a session (hereinafter, call session information, arrival / departure determination flag and call information are referred to as “information relating to a session”), the control session information is paid out to any information display terminal 20. It is to manage whether it is a thing. In FIG. 5, for convenience of explanation, regular numerical values are exemplified as control session information and “Call-ID”, but generally random numbers or the like are stored.

  The arrival / departure association ID table 124 is a table for managing an inter-arrival association ID (a pseudonym information issued by the session management server 100 as a pseudonym of call session information that uniquely identifies a session established by SIP). For example, as shown in FIG. 6, the departure / arrival association ID table 124 stores control session information, contract service ID, departure / arrival association ID, pseudonym ID, and status in association with each other. .

  These pieces of information stored in the between-incoming / outgoing association ID table 124 are registered when the session management server 100 issues an inbound / outbound association ID and a pseudonym ID. Here, the connection ID between outgoing and incoming calls is used in order for the service providing server 200 to associate each information display terminal 20 during a call, that is, each information display terminal 20 each of which a user is making a call with each SIP phone 30. This is the ID to use. As will be described later, since the incoming / outgoing association ID is newly paid out for each established session (that is, for each call), the service providing server 200 provides each information display terminal 20 for each session (that is, for each call). Can be linked.

  The pseudonym ID is issued by the session management server 100 for each combination of the information display terminal 20 and the service used by the information display terminal 20 and for each established session (that is, for each call). is there. For example, it is information that uniquely identifies a combination of the information display terminal 20 and a service used by the information display terminal 20, and the service providing server 200 determines which information display terminal 20 of the two information display terminals 20. This ID is used to specify whether or not. That is, the service providing server 200 specifies the two information display terminals 20 by using the link ID between departure and arrival, and controls to link the services provided to the two specified information display terminals 20. However, it is not possible to provide services by distinguishing the two information display terminals 20 only by using the ID between the arrival and departure times. In this respect, since the kana ID is issued for each combination of the information display terminal 20 and the service, the service providing server 200 distinguishes each of the two information display terminals 20 using the kana ID, and each information Control can be performed so as to provide a service adapted to the display terminal 20.

  The status indicates whether or not the user identified by the pseudonym ID is using the service identified by the contract service ID.

  As shown in FIG. 7, the conference room service table 125 is a table for managing the telephone number of the conference room server in association with the contract service ID. Since the conference room service table 125 stores “conference room server URL” in association with the “contract service ID” managed by the user contract service management table 121, the session management server 100 stores “contract service ID”. The “conference room server URL” can be specified using the key and notified to each information display terminal 20. These pieces of information stored in the conference room service table 125 are registered in advance and appropriately registered in the service providing system according to the first embodiment.

  As shown in FIG. 8, the conference room correspondence management table 126 is a table for managing group IDs in association with conference room IDs. For example, the conference room correspondence management table 126 is the timing at which the conference room ID is issued by the service providing server 200, and the session information for control of the information display terminal 20 from which the conference room ID is issued and the conference room ID issued. And a group ID that can be specified from the control session management table 123 by using as a key. By doing so, it is possible to grasp which conference ID is used by the information display terminal 20 of which group ID.

  The data table 127 is a table that stores data that is a target of data transfer. For example, as shown in FIG. 9, the data table 127 stores data file names and data in association with each other. In the data transfer, the session management server 100 does not necessarily acquire the data to be transferred, but when the session management server 100 acquires the data, the session management server 100 appropriately acquires the acquired data. What is necessary is just to store in the data table 127. FIG.

  As shown in FIG. 2, the control unit 130 is particularly closely related to the present invention, as shown in FIG. 2, a call session information collection unit 131, an arrival / departure association ID issuing unit 132, a conference room related control unit 133, It has a delivery request determination unit 134 and a data delivery control unit 135.

  For each information display terminal 20 that has transmitted a service start request, the call session information collection unit 131 establishes communication established between the SIP phone 30 used in combination with the information display terminal 20 and another SIP phone 30. Call session information for identifying is collected.

  The link ID issuing unit 132 between arrivals and departures specifies call session information indicating the same communication from the plurality of call session information collected by the call session information collection unit 131, and is identified by the identified call session information. A link ID between departure and arrival for linking each information display terminal 20 used in combination with each phone 30 is issued to each information display terminal. Further, the arrival / departure association ID issuing unit 132 issues a pseudonym ID.

  When the conference room related control unit 133 receives a call connection request (a three-party session cooperation request) with a new information display terminal from an information display terminal that is connected to another information display terminal through a call, the conference room related control unit 133 issues the connection request. It is determined whether or not the transmitted pseudonym ID of the information display terminal is the pseudonym ID issued by the device itself, or the caller of the information display terminal (HGW) that transmitted the connection request is identified and the group ID is issued. Then, a two-party connection or a three-party connection is executed via the conference room server to establish a call connection with a new information display terminal.

  When the delivery request determination unit 134 receives a delivery request for requesting delivery of data from one information display terminal 20 between the information display terminals 20 provided so as to cooperate with the service from the service providing server 200, the delivery request determination unit 134 Whether the requesting information display terminal 20 is the information display terminal 20 used in combination with the SIP phone 30 that has established communication identified by the call session information collected by the call session information collection unit 131. judge. That is, it is determined whether or not the user of the information display terminal 20 that is the request source of the delivery request is the user of the SIP phone 30 that has established communication by SIP. For example, it is determined whether or not the user is a user who is currently talking.

  When the delivery request determination unit 134 determines that the user of the information display terminal 20 that is the request source of the delivery request is the user of the SIP phone 30 that has established communication by SIP, the data delivery control unit 135 delivers According to the request, data used for delivery is obtained from the data storage source, and data delivery is controlled using the obtained data.

(Service providing server configuration)
The service providing server 200 is realized by providing each unit described below in a general-purpose server or the like, and as particularly closely related to the present invention, as shown in FIG. Unit 220 and control unit 230.

  The communication unit 210 includes a general interface and library for HTTP communication, and transmits and receives information to and from the session management server 100, the information display terminal 20, and a SIP proxy.

  The storage unit 220 stores information used for various controls in the control unit 230, and particularly as closely related to the present invention, as shown in FIG. 10, a Web session information management table 221 and a data table 222 are stored. Have.

  The Web session information management table 221 is pseudonym information issued by the session management server 100 as a pseudonym of call session information that uniquely identifies communication established by SIP, and links each information display terminal 20 together. This is a table for managing the information). For example, as shown in FIG. 11, the Web session information management table 221 stores Web session information, an arrival / departure association ID, a pseudonym ID, and an arrival / departure determination flag in association with each other.

  Among these pieces of information stored in the Web session information management table 221, Web session information (provided for the Web browser of the information display terminal 20 so that the service providing server 200 can communicate with the information display terminal 20). Information) is paid out and registered when the service providing server 200 receives a service use request from the information display terminal 20. Further, the arrival / departure association ID, the pseudonym ID, and the arrival / departure determination flag are registered when the service providing server 200 receives a service use request from the information display terminal 20.

  Here, the Web session information is used by the service providing server 200 to identify the information display terminal 20. That is, when the service providing server 200 receives an access from the information display terminal 20, the service providing server 200 acquires the Web session information given to the Web browser of the information display terminal 20 and identifies the information display terminal 20. In addition, the connection / destination link ID is used by the service providing server 200 to link each of the information display terminals 20 during a call, that is, each of the information display terminals 20 each of which a user is calling using the SIP phone 30. It is done.

  Further, the pseudonym ID is used for specifying which information display terminal 20 of the two information display terminals 20 the service providing server 200 is. That is, the service providing server 200 can specify the information display terminal 20 by using the connection ID between arrivals and departures and control the service provided to the identified information display terminal 20 to cooperate, It is impossible to provide a service by distinguishing each of the plurality of information display terminals 20 only by using the association ID. In this regard, since the kana ID is issued for each combination of the information display terminal 20 and the service, the service providing server 200 distinguishes each of the information display terminals 20 using this kana ID, and each information display terminal 20 It can be controlled to provide a service adapted to the. That is, by using the pseudonym ID, the service providing server 200 can specify not only “any one of the users in a call” but also “which user”. The arrival / departure determination flag is used by the service providing server 200 to determine whether the SIP phone 30 used in combination with the information display terminal 20 is the calling side or the called side.

  The data table 222 is a table that stores data to be transferred. For example, as shown in FIG. 12, the data table 222 stores a kana ID and data in association with each other. That is, the data table 222 stores the correspondence between the user and the data, and stores the kana ID for identifying the user and the data in association with each other. Note that the service providing server 200 may store the correspondence between the pseudonym ID and the data in the data table 222 from the beginning. For example, when generating a data download screen, the data of the other party or the service providing server The information about 200 may be stored in the data table 222 in association with the pseudonym ID of the user of the SIP phone 30 as download data so that the call partner data and the data of the service providing server 200 can be downloaded.

  Returning to FIG. 10, the control unit 230 is particularly closely related to the present invention, as shown in FIG. 10, as shown in FIG. 10, the arrival / departure linking ID collection unit 231, the service provision control unit 232, and the data transfer unit 233. With.

  The arrival / departure association ID collection unit 231 collects the arrival / departure association ID issued by the session management server 100 for each information display terminal 20 that requests the provision of the service, and stores it in the Web session information management table 221. That is, the arrival / departure association ID collection unit 231 collects the arrival / departure association ID from the information display terminal 20 when receiving a service provision request from the information display terminal 20. As described above, since the connection ID between departures and arrivals is newly issued for each established session (that is, for each call), the connection ID collection unit 231 between arrivals and departures is received from each information display terminal 20. As a result of collecting the association IDs, the same arrival / departure association IDs are also collected from the two information display terminals 20. Further, the departure / arrival linking ID collection unit 231 according to the first embodiment collects the kana ID and the arrival / departure determination flag for each information display terminal 20 and stores them in the Web session information management table 221.

  The service provision control unit 232 specifies an arrival / departure association ID indicating that the service is linked from among a plurality of arrival / departure association IDs collected by the arrival / departure association ID collection unit 231, and identifies the identified arrival / departure association Service provision is controlled so that the services provided to each information display terminal 20 that is the collection source of the attached ID are linked.

  The data transfer unit 233 transfers data related to the service according to control by the session management server 100. That is, in the service providing system according to the first embodiment, the data transfer is performed in the session management server 100 by the “information requesting terminal of the request for the transfer request and the SIP phone that established the communication identified by the collected call session information. It is controlled by determining whether or not the information display terminal is used in pairs. In other words, the session management server 100 notifies the service providing server 200 of information such as which data is to be delivered and which information display terminal 20 should be delivered, and controls the service providing server 200. Thus, it can be said that it controls the entire data transfer. The data transfer unit 233 receives such control information from the session management server 100 and transfers data.

  Here, service provision by the service provision server 200 will be considered again. That is, the point that the service provision by the service provision server 200 is controlled based on the relationship between the information display terminals 20 is the same as the conventional service provision server that controls the service based on a pre-registered buddy list. However, it will be described how the service providing server 200 in the first embodiment grasps the “relationship between the information display terminals 20”.

  That is, the service providing server 200 according to the first embodiment, like the conventional service providing server, uses the relationship registered in the storage unit in advance (for example, the relationship registered in the buddy list) as “the relationship between the information display terminals 20”. Instead, the service provision control unit 232 grasps the “relationship between the information display terminals 20” using the arrival / departure association ID. In other words, the service providing server 200 has such a temporary communication relationship even when the relationship with the terminal that is the communication partner is temporary, such as the relationship between the SIP phones 30 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 communications performed in each information display terminal 20 with each other.

  Note that, as in the first embodiment, when the first communication is communication in the process of establishing communication by SIP, the “relationship between the information display terminals 20” is an authenticated relationship by SIP. There is a meaning. That is, in SIP communication, Digest (digest) authentication is generally performed, and the fact that communication is established between SIP phones 30 by SIP means that the relationship between each information display terminal 20 has been authenticated. It shows that there is.

(Configuration of HGW)
The HGW 10 shown in FIG. 13 is realized by providing each unit described below in a general-purpose gateway device or the like. Particularly, as closely related to the present invention, the SIP communication unit / HTTP communication unit 11 and the storage Unit 12 and control unit 13.

  The browser session information management table 12a stores in advance browser session information assigned to the subordinate information display terminal 20. For example, as shown in FIG. 14, the browser session information management table 12 a uniquely identifies information (SIP phone ID) for uniquely identifying the SIP phone 30 and the information display terminal 20 used in combination with the SIP phone 30. Information to be identified (information display terminal ID) and browser session information for specifying the information display terminal 20 are stored in advance in association with each other. Further, the browser session information management table 12a stores Call-ID, From, To, an arrival / departure determination flag, and call information in association with each other. Of these pieces of information stored in the browser session information management table 12a, Call-ID, From, and To are, for example, collected and registered by the HGW 10. The arrival / departure determination flag is information generated by the HGW 10 itself from information included in communication established by SIP. Since the HGW 10 knows the SIP phone 30 connected to the subordinate, the HGW 10 can determine whether the corresponding call is an outgoing call or an incoming call.

  Returning to FIG. 13, the control unit 13 has a service use control unit 13 a and a data transfer unit 13 b as shown in FIG. 13, particularly as closely related to the present invention.

  The service usage control unit 13a controls service usage by the information display terminal 20. The data transfer unit 13b transfers data related to the service according to control by the session management server 100.

(Conference room server configuration)
The conference room server 300 is realized by providing each unit described below in a general-purpose server or the like, and particularly as closely related to the present invention, as shown in FIG. 15, a communication control I / F unit 310, a storage unit 320, and a control unit 330.

  The communication control I / F unit 310 includes a general interface and library for HTTP communication, and is connected to other server devices such as the session management server 100, the information display terminal 20, and the SIP proxy. Send and receive information.

  The storage unit 320 stores information used for various controls in the control unit 330, and particularly as closely related to the present invention, as shown in FIG. 15, a conference room management table 321 and a conference session information management table 322.

  The conference room management table 321 is a table for managing which user is using the conference room. For example, as shown in FIG. 16, the conference room management table 321 includes a conference room ID that uniquely identifies a conference room that connects N persons and a SIP that uses the conference room specified by the conference room ID. The SIP-URI of the phone (HGW), the start time when the conference room is used, the end time when the use of the conference room is ended, and the use status of the conference room are managed.

  The conference session information management table 322 stores detailed information of the user who uses the conference room ID whose status in the conference room management table 321 is “in use”. For example, the conference session information management table 322 uses the conference room specified by the conference room ID in association with the conference room ID whose status in the conference room management table 321 is “in use”. Call session information such as information display terminals, departure / arrival flags, call information, and the like are stored.

  Returning to FIG. 15, the control unit 330 includes a conference room ID issuing unit 331 and an audio bridge control unit 332 as shown in FIG. 15, particularly as closely related to the present invention.

  The conference room ID issuing unit 331 issues a conference room ID when a conference room reservation request is received from the session management server 100. After that, when user homes are connected via the conference room server 300, the conference room ID issuing unit 331 acquires call session information by uniquely collecting call session information that uniquely identifies communication established by SIP. In addition, a departure / arrival determination flag is acquired. Then, the conference room ID issuing unit 331 stores the collected information in the conference session information management table 322.

  The voice bridge control unit 332 performs voice bridge connection between a plurality of user homes. For example, the voice bridge control unit 332 transmits the conference room ID to the session management server 100 by the conference room ID issuing unit 331 and uses the “conference room ID” and “call session information” received from the session management server as keys. By identifying From and To from the conference session information management table 322, the HGW to be connected by voice bridge is identified. Then, the voice bridge control unit 332 starts a voice bridge between the HGWs (two-party voice bridge), and notifies the session management server of a two-party voice bridge start completion notification. Also, the voice bridge control unit 332 associates the SIP-URI of the HGW and the conference room ID that are connected here by voice bridge and stores them in the conference room management table 321.

  The voice bridge control unit 332 matches the notified “conference room ID” when the session management server 100 notifies the call session information and conference room ID of the user's house additionally connected by the voice bridge. Similarly, the call session information of the user house to be additionally connected received in the same manner is stored in the conference session information management table 322, and the three-party voice bridge is started. Also, the voice bridge control unit 332 stores the SIP-URI of the HGW newly connected by voice bridge here in the conference room management table 321 in association with the additionally connected conference room ID.

(Configuration of SIP phone)
The SIP phone 30 is realized by a general-purpose SIP phone, and particularly as closely related to the present invention, as shown in FIG. 18, a SIP communication unit 31, an input unit 32, an output unit 33, and an input unit 33 are provided. And an output control I / F unit 34.

  Since both are the same as the general-purpose SIP phone 30, a brief description will be given. The input unit 32 inputs information used for the SIP phone 30, operation instructions for performing various processes, and the like using number keys, a microphone, and the like. The output unit 33 outputs the results of various processes by the SIP phone 30 and operation instructions for performing various processes to a display and a speaker. The input / output control I / F unit 34 includes the input unit 32, The information transfer between the output unit 33 and the SIP communication unit 31 is controlled. The SIP communication unit 31 includes a general interface and library for SIP, and is connected to the other SIP phone 30 (via the HGW 10). Send and receive information.

(Configuration of information display terminal)
The information display terminal 20 is realized by providing each unit described below in a general-purpose PC, an information home appliance, and the like, and particularly as closely related to the present invention, as shown in FIG. 21, an input unit 22, an output unit 23, an input / output control I / F unit 24, and a control unit 25.

  The input unit 22 inputs information used for the information display terminal 20 and operation instructions for performing various processes using a keyboard, a mouse, a remote controller, and the like, and the output unit 23 results from various processes performed by the information display terminal 20. In addition, an operation instruction for performing various processes is output to a display, a printer, or the like. The input / output control I / F unit 24 includes an input unit 22, an output unit 23, an HTTP communication unit 21, and a control unit 25. The HTTP communication unit 21 includes a general interface and library for HTTP communication, and transmits / receives information to / from the service providing server 200 (via the HGW 10).

  As shown in FIG. 19, the control unit 25 includes a service use unit 25a and a delivery request unit 25b, particularly as closely related to the present invention.

  The service using unit 25a uses a service provided by the service providing server 200. Specifically, the service utilization unit 25a transmits a service provision start request for starting the provision of the service to the session management server 100, or transmits a service utilization request for requesting the use of the service to the service provision server 200. .

  The transfer request unit 25 b transfers data related to the service in accordance with control by the session management server 100. Specifically, the delivery request unit 25b transmits a delivery request for requesting delivery of data related to the service to the session management server 100.

[Procedure of processing by the service providing system according to the first embodiment]
Subsequently, the flow of processing by the service providing system according to the first embodiment will be described with reference to FIGS.

(Procedure for service provision)
As shown in FIG. 20, first, the SIP proxy controls communication by both SIP phones 30 (SIP communication unit 31), so that SIP communication in steps S1 to S3 is performed between both SIP phones 30 (SIP communication unit 31). As a result, communication (call) is established between both SIP phones 30 by SIP in step S4. Note that Digest authentication, REGISTER processing, and the like in SIP communication are not shown, but are performed prior to step S1 as in general SIP communication.

  When communication is established between both SIP phones by SIP, the HGW 10 (service usage control unit 13a) acquires call session information by uniquely collecting communication established by SIP, and receives and arrives. A determination flag is acquired (step S5). For example, the HGW 10 collects “Call-ID”, “From (SIP-URI)”, and “To (SIP-URI)” as call session information from information included in the communication established by SIP. Get in. Further, the HGW 10 (service use control unit 13a) itself generates a “departure / departure determination flag” indicating whether both SIP phones are on the caller side or the callee side from information included in the communication established by the SIP. The HGW 10 (service usage control unit 13a) issues a signed certificate of the HGW for the acquired call session information and the like, and verifies the call session information by attaching the signed certificate to the call session information. It may be issued in a possible format.

  In the first embodiment, the method in which the HGW 10 collects call session information by itself and generates the arrival / departure determination flag by itself has been described. However, the present invention is not limited to this method. For example, the HGW 10 may collect call session information collected by the SIP proxy by receiving it from the SIP proxy and generate the arrival / departure determination flag by itself. Further, information such as call session information and a departure / arrival determination flag may be added to information notified from the SIP proxy.

  Here, the point that the SIP proxy collects call session information will be briefly described. Since the SIP proxy is a device that controls communication established by SIP or communication established by SIP, the SIP proxy itself. In general, information related to a session established by control of a device is managed. Therefore, when the SIP proxy establishes a session between the two SIP phones under its own control, “Call-ID”, “From (SIP-URI)”, “To (SIP-URI) as call session information Can be collected from the SIP signal of the established session. Then, the SIP proxy transmits the collected call session information to the HGW that connects the originating SIP phone and the HGW that connects the called SIP phone under the push type. Then, the HGW can collect the call session information by receiving the call session information collected by the SIP proxy from the SIP proxy.

  In this method, the SIP proxy can verify the call session information by issuing a SIP proxy signed certificate for the call session information and attaching the signed certificate to the call session information. It may be issued in a format.

  Returning to FIG. 20, subsequently, the HGW 10 (service use control unit 13a) collects the SIP phone ID, which is information for uniquely identifying the subordinate SIP phone, from the information included in the SIP communication (step S6). The SIP phone ID is, for example, an extension number of a SIP phone. In the case of a configuration in which a plurality of SIP phones are connected under the HGW 10, the SIP-URI is assigned to the HGW 10, and an extension number is assigned to each of the SIP phones 30 under the HGW 10.

  Then, the HGW 10 (service use control unit 13a) specifies the information display terminal 20 used in combination with the SIP phone 30 that established communication by SIP in step S4 (step S7). Specifically, the HGW 10 (service usage control unit 13a) first identifies the information display terminal 20 by searching the browser session information management table 12a using the SIP phone ID as a key, and the browser of the identified information display terminal 20 Information that is used in combination with the SIP phone 30 that establishes communication by SIP when the session information is compared with the browser session information of each of the plurality of information display terminals 20 that poll the HGW, and the browser session information matches. The display terminal 20 is specified.

  Then, the HGW 10 (service usage control unit 13a) issues an access destination change instruction to the information display terminal 20 specified in step S7. Specifically, a redirect instruction for instructing the specified information display terminal to change the access destination to the URL of the session management server 100 is performed together with the call session information and the like (step S8). At this time, for the purpose of notifying the session management server 100 of the URL of the HGW 10, the HGW 10 (service usage control unit 13 a) in the first embodiment also includes the URL of the HGW 10 in the redirect instruction. That is, the URL of the HGW 10 included in the redirect instruction is transmitted to the session management server 100 by the information display terminal 20. In the first embodiment, the HGW 10 stores the URL of the session management server 100 in the storage unit in advance, so that a redirect instruction can be issued to change the access destination to the URL. As a result, the information display terminal 20 receives the redirect instruction and changes the access destination from the URL of the HGW 10 to the URL of the session management server 100.

  Then, the information display terminal 20 (service utilization unit 25a) is redirected, the connection destination is changed to the session management server 100, and a service start request for requesting to start the service is transmitted to the session management server 100 (step) S9). At this time, the information display terminal 20 (service use unit 25a) transmits call session information and the like and the URL of the HGW to the session management server.

  On the other hand, when the session management server 100 (call session information collection unit 131) receives call session information or the like transmitted from the information display terminal, the session management server 100 (call session information collection unit 131) verifies the call session information or the like (step S10). That is, the session management server 100 (call session information collection unit 131) verifies that the call session information or the like is authentic information. For example, the session management server 100 (call session information collection unit 131) verifies that call session information or the like is authentic information by making an inquiry to the SIP proxy. When call session information or the like is received in a verifiable format with a signed certificate attached, the session management server verifies the signed certificate so that the call session information or the like is obtained. It may be verified that the information is genuine.

  Subsequently, when the session management server 100 (call session information collection unit 131) confirms that the call session information or the like is authentic information as a result of the verification in step S10, the call session information or the like, the URL of the HGW 10, and The start time as the call information is stored in the control session management table, the control session information is paid out, and the issued control session information is stored in the control session management table and the between-arrival / reception link ID table 124 (step S11). .

  Subsequently, the session management server 100 (call session information collection unit 131) confirms the services available to the information display terminal 20 (originating side) that has transmitted the service start request in the user contract service management table 121, and the contract service. ID is acquired (step S12).

  Then, the session management server 100 (call session information collection unit 131) generates a control page (step S13).

  Subsequently, the session management server 100 (call session information collection unit 131), with respect to the information display terminal 20, a connection destination monitoring function, control session information issued in step S11, and a control page generated in step S13. The contract service ID acquired in step S12 is transmitted (step S14). Here, the connection destination monitoring function is, for example, a Java (registered trademark) Script file and is installed in the information display terminal 20 to establish communication between the information display terminal 20 and the session management server 100. This is a function for monitoring the connection destination of the information display terminal 20.

  Then, the information display terminal 20 displays the control page transmitted from the session management server 100 from the web browser (step S15). Further, the information display terminal 20 installs the connection destination monitoring function transmitted from the session management server 100. Then, the connection destination monitoring function unit establishes communication with the session management server 100 and performs polling using the control session information transmitted from the session management server 100, thereby connecting the connection destination of the information display terminal. Are periodically transmitted to the session management server 100. On the other hand, the service providing server periodically monitors the connection destination of the information display terminal that has issued the control session information by confirming the control session information used for polling (step S16).

  In addition, although the information display terminal 20 on the transmission side has been described so far, the same processing is performed on the information display terminal 20 on the reception side. In this way, the connection monitoring function is installed in both the outgoing-side information display terminal 20 and the incoming-side information display terminal 20, and communication is established between each connection destination monitoring function unit and the session management server 100.

  Subsequently, as shown in FIG. 21, the user of the information display terminal 20 on the transmission side selects a service from the control page displayed on the Web browser (step S17), whereby the information display terminal 20 (service The utilization unit 25a) transmits a service start request to the session management server 100 (step S18). At this time, the information display terminal 20 (service utilization unit 25a) transmits the contract service ID of the selected service to the session management server 100 using the control session information transmitted in step S14. The service start request may be transmitted via the connection destination monitoring function, as shown in FIG. 21, or directly from the information display terminal to the session management server 100 without via the connection destination monitoring function. May be.

  Then, the session management server 100 (departure / arrival linking ID issuing unit 132) confirms that the control session information transmitted from the information display terminal 20 is registered in the control session management table 123. (Step S19), a link ID between arrival and departure and a pseudonym ID are issued (Step S20). A description will be given of an implementation example in which the issued / arrival association ID and pseudonym ID are stored in the between-arrival / association ID management table 124. For example, when the user of the information display terminal 20 on the transmission side selects a service from the control page (when the service is activated), the information display terminal 20 (service use unit 25a) identifies a service ID that identifies the selected service. Is transmitted to the session management server 100. At this time, the information display terminal 20 (service use unit 25a) uses the control session information. Then, the session management server 100 (departure / arrival linking ID issuing unit 132) refers to the control session management table 123 using the control session information used by the information display terminal 20 as a search key, and is transmitted from the information display terminal 20. It is confirmed that the control session information is registered in the control session management table 123. Then, the session management server 100 (departure / arrival association ID issuing unit 132) refers to the inter-departure association ID table 124 using the confirmed control session information. When the control session information is transmitted for the first time by the information display terminal 20 (service utilization unit 25a), the control session information should not yet be stored in the arrival / departure association ID table 124. For this reason, the session management server 100 (departure / arrival linking ID issuing unit 132) issues an arriving / departing linking ID and a pseudonym ID, and associates the issued arriving / departing linking ID and pseudonym ID with the control session information. It is stored in the between-arrival and arrival association ID table 124, and further the contract service ID and status (“in use”) are stored.

  Here, the outgoing / incoming link ID is an ID used in the service providing server 200 to link the outgoing information display terminal 20 and the incoming information display terminal 20. Since communication established by SIP between the originating side SIP phone 30 and the terminating side SIP phone 30 can be uniquely identified by the call session information, the service providing server 200 uses the call session information. For example, the information display terminal 20 on the transmission side and the information display terminal on the reception side can be associated with each other. However, in the case where it is considered that there is a security problem in disclosing the call session information to the service providing server 200 (for example, so that the service providing company does not know which users are accessing from each other) The call session information itself should not be disclosed to the service providing server 200. Therefore, in the first embodiment, in order to make call session information anonymous and capable of being associated, the session management server 100 issues an arrival / departure association ID in the form of a pseudonym. The pseudonym ID is an ID used in the service providing server 200 to identify a calling user or a receiving user. That is, since it is not possible to specify the user only by the ID between the arrival and departure, the information display terminal 20 and the service used by the information display terminal 20 for the purpose of specifying the user by the service provider For each combination, the session management server 100 issues.

  The session management server 100 (departure / arrival association ID issuing unit 132) sends the URL of the service providing server 200 (obtained in step S12), the arrival / departure association ID, and the kana ID to the information display terminal 20. The departure / arrival determination flag is transmitted (step S21). In addition, the session management server 100 (departure / arrival association ID issuing unit 132) according to the first embodiment transmits the inter-departure association ID, the pseudonym ID, and the arrival / departure determination flag in a verifiable format. For example, the session management server 100 (departure / arrival association ID issuing unit 132) issues a signed certificate of the session management server with respect to the inter-departure association ID, pseudonym ID, and arrival / departure determination flag, and issues the signed certificate By attaching it to the interlinking ID, kana ID, and arrival / departure determination flag, the inter-departure association ID, kana ID, and arrival / departure determination flag are issued in a verifiable format. Note that the method is not limited to the method of attaching a signed certificate, and a method of not attaching a certificate may be used.

  On the other hand, the information display terminal 20 (service use unit 25a) connects to the URL transmitted from the session management server 100, and uses the service ID and pseudonym ID and the arrival / departure determination flag transmitted from the session management server 100 as the service. It transmits to the providing server 200 (step S22).

  Then, when the service providing server 200 (departure / arrival association ID collection unit 231) receives the arrival / departure association ID, the pseudonym ID, and the arrival / departure determination flag transmitted from the information display terminal 20, the service provision server 200 (departure / arrival association ID, kana) The ID and the arrival / departure determination flag are verified (step S23). In other words, the service providing server 200 (departure / arrival association ID collection unit 231) verifies the signed certificate attached to the arrival / departure association ID, the pseudonym ID, and the arrival / departure determination flag. It is verified that the kana ID and the arrival / departure determination flag are genuine information. In addition, as a method for verifying that the connection ID between departure and arrival, the pseudonym ID, and the arrival / departure determination flag are authentic information, a method of inquiring the session management server 100 may be used.

  Subsequently, when the service providing server 200 (departure / arrival association ID collection unit 231) confirms that the inter-departure / arrival association ID, the pseudonym ID, and the arrival / departure determination flag are authentic information as a result of the verification in step S23, the arrival / departure is performed. Information to be given to Web communication performed by the information display terminal 20 that has transmitted the association ID, pseudonym ID, and arrival / departure determination flag (Web communication performed by the information display terminal 20 with the service providing server 200 in order to receive service provision) Web session information is paid out and stored in the Web session information management table 221 (step S24). Then, the Web session information management table 221 stores the Web session information, the departure / arrival linking ID, the pseudonym ID, and the arrival / departure determination flag. As described above, if the service providing server 200 also stores the kana ID and the arrival / departure determination flag, the service providing server 200 provides the service based on the kana ID and the arrival / departure determination flag when providing the service. Can also be controlled.

  Subsequently, the service providing server 200 (departure / arrival linking ID collection unit 231) generates a service providing screen (step S25), and displays the generated service providing screen together with the Web session information paid out in step S24 on the information display terminal 20. (Step S26).

  Then, a service providing screen is displayed on the Web browser of the information display terminal 20 (step S27).

  By the way, in the first embodiment, the session management server 100 (departure / arrival linking ID issuing unit 132) controls the information display terminal 20 on the caller side in response to the service start request in step S18 (or immediately) and also receives an incoming call. The information display terminal 20 on the side is also controlled (steps S28 to S35). That is, although not shown in FIG. 21, the incoming-side information display terminal 20 also proceeds to step S28 by the same processing procedure as steps S18 to S20. Step S28 is processing corresponding to step S21 performed for the information display terminal 20 on the transmission side. In addition, the information display terminal 20 on the receiving side also performs the same processing procedure as steps S21 to S27, that is, as a result of performing steps S31 to S35. . For this reason, both the information display terminal 20 on the transmission side and the information display terminal 20 on the reception side immediately enter the state of using the service.

  That is, the service providing server 200 (service providing control unit 232) pays out Web session information to the information display terminal on the calling side in step S24, and stores it in the Web session information management table 221 together with the connection ID between arrival and arrival. In step S31, the Web session information is paid out to the information display terminal 20 on the receiving side and stored in the Web session information management table 221. Then, in step S38, the service providing server 200 (the service providing control unit 232), among the plurality of arrival / departure association IDs stored in the Web session information management table 221, each predetermined arrival / departure association ID is a service. , The services provided by using the Web session information stored in association with the departure / arrival linking IDs are associated with each other and controlled (steps S36 to S39). ).

  For example, step S36 to step S39 will be described. One information display terminal 20 uploads image data to the service providing server 200 by web communication to which the web session information paid out in step S24 is added, and the other It is assumed that the information display terminal 20 is accessing the service providing server 200 through Web communication to which the Web session information paid out in step S31 is assigned. Then, the service providing server 200 controls the service so as to transmit the image data to the other information display terminal 20, so that the image data is transmitted to the other information display terminal 20, and the other information display terminal 20 outputs the data. The image data is displayed on the part.

  As described above, a method has been described in which the session management server 100 controls the information display terminal 20 on the receiving side at the same time (or immediately) as controlling the information display terminal on the transmission side, but the present invention is limited to this. is not. As another method, for example, when the information display terminal 20 on the receiving side selects the service itself and transmits a service start request to the session management server 100 in the same manner as the information display terminal 20 on the calling side, The present invention can be similarly applied to a method in which the management server 100 controls the information display terminal 20 on the called side. Alternatively, for example, when the originating information display terminal 20 requests the session management server 100 to perform the terminating information display terminal control, the session management server 100 performs the processing after step S28. The present invention can be similarly applied to the method of starting the process.

  Then, as shown in FIG. 22, the service providing server 200 (service providing control unit 232) provides a service to the user A by Web communication to which the Web session information paid out in Step S24 is provided. A service screen showing store information and the like is output to the display terminal 20 (step S101).

  Thereafter, when the service screen displayed on the information display terminal 20 of the user A's home is clicked by the user (step S102), the information display terminal 20 (service use unit 25a) issues a three-party session cooperation request as a session. It transmits to the management server 100 (step S103). For example, when the information display terminal 20 of the user A's home receives a click on the contact information of the store (phone number “0333333333”) via a mouse or the like, the session management server 100 sends information along with the three-party session cooperation request. The pseudonym ID issued for each combination of the display terminal 20 and the service used by the information display terminal 20 and the called telephone number “0333333333” are transmitted to the session management server 100.

  Then, in the session management server 100 (conference room related control unit 133), the pseudonym ID added to the three-party session cooperation request received from the information display terminal of the user A's home is the pseudonym ID issued by the own device. It is determined whether or not (step S104). When the session management server 100 (conference room related control unit 133) determines that the received pseudonym ID is the pseudonym ID issued by the own device, the HGW 10 (user A) that transmitted the three-party session cooperation request Is identified (step S105), and a group ID is issued (step S106).

  For example, the session management server 100 (conference room related control unit 133) determines whether or not the pseudonym ID added to the received three-party session cooperation request is stored in the arrival / departure association ID table 124. It is determined whether or not the pseudonym ID is issued. Then, when the received kana ID is stored in the arrival / departure association ID table 124, the session management server 100 (conference room related control unit 133) displays “control session information” corresponding to the kana ID between the arrival and departure times. It is specified from the association ID table 124. Subsequently, the session management server 100 (conference room related control unit 133) specifies “call-ID” corresponding to the specified “control session information” from the control session management table 123. Here, for example, “call-ID” is used as an ID for uniquely specifying a call session, and isub or the like can also be used. Then, the session management server 100 (conference room related control unit 133) specifies from the control session management table 123 a record in which the same “call-ID” is stored as the specified “call-ID”. Thus, the session management server 100 (conference room related control unit 133) can identify “departure / departure” by referring to the “departure / departure determination flag” of the identified record, and further, the group issued to the identified record Store the ID.

  The session management server 100 (conference room related control unit 133) that has issued the group ID in this way transmits a conference room reservation request to the conference room server 300 through communication using an arbitrary protocol such as HTTP (step) S107). At this time, the session management server 100 (conference room related control unit 133) specifies the contract service ID from the arrival / departure association ID table 124 using the pseudonym ID included in the three-party connection request received in S103 as a key. . Then, the session management server 100 (conference room related control unit 133) specifies the URL of the conference room server 300 from the conference room service table 125 using the specified contract service ID as a key, and accesses the specified URL to access the conference room. A conference room reservation request is transmitted to the server 300. Then, the conference room server 300 (conference room ID issuing unit 331) refers to the conference room management table 321, issues a conference room ID whose status is not in use, and outputs it to the session management server 100 together with a reservation completion notification ( Step S108 and Step S109).

  Then, the session management server 100 (conference room related control unit 133) associates the group ID issued in step S106 with the conference room ID received in step S109, and stores them in the conference room correspondence management table 126 (step). S110). Thereafter, the session management server 100 (conference room related control unit 133) transmits a call destination change instruction to the HGW 10 of the user A home and the user B home, so that the HGW 10 of the user A home and the user B home Then, the destination of the SIP phone 30 is changed to the conference room server, and the SIP phones 30 of the user A home and the user B home are connected via the conference room server 300 (steps S111 to S113).

  For example, the session management server 100 (conference room related control unit 133) that stores the group ID and the conference room ID in the conference room correspondence management table 126 in association with each other, the information display terminal 20 of the user A home and the user B home. In addition, the call session information, the telephone number of the conference room server 300, and the session information for control for specifying the between-arrival / inbound association ID from the between-inbound / outbound association ID table 124 are transmitted by redirect communication to the HGW 10. Then, the HGW 10 of the user A home and the user B home verifies the received call session information. Specifically, the HGWs 10 of user A's home and user B's home verify whether the call session information that completely matches the received call session information exists in the browser session information management table 12a. If there is call session information in the browser session information management table 12a, the HGWs of user A's home and user B's home specify a terminal (SIP phone) that is in a call. In addition, the HGW 10 of the user A's home and the user B's home receives a control instruction for changing the call destination to the phone number of the conference room server 300 that has received the call destination of the call connection connected between them ( When a call instruction is sent to the SIP phone and a response is received, the conference room server 300 is called. As a result, the SIP phones at user A's home and user B's home are connected via the conference room server 300. The connection may be changed by the SIP phone, or the HGW 10 may change the connection destination to the conference room server 300 while maintaining the voice path between the SIP phone and the HGW.

  Returning to FIG. 22, after that, the HGW 300 in the user A's home acquires call session information that uniquely identifies the communication established by the SIP, and acquires the arrival / departure determination flag (step S114). . Similarly, the conference room server 300 acquires call session information that uniquely identifies communication established by SIP, and acquires the arrival / departure determination flag (step S115). Then, the HGW 10 at the user A home sends a connection completion notification indicating that the SIP phone 30 at the user A home and the SIP phone 30 at the user B home are connected via the conference room server 300. (Step S116). Similarly, the conference room server 300 also receives a connection completion notification indicating that it is connected to the SIP phone 30 of the user A home, and a connection completion notification indicating that it is connected to the SIP phone 30 of the user B home. It transmits to the session management server 100 (step S117). The call session information and the arrival / departure determination flag are also acquired for the HGW 30 of the user B home, and the SIP phone 30 of the user A home and the SIP phone 30 of the user B home are connected via the conference room server 300. A connection completion notification indicating the connection is transmitted to the session management server 100 (step S118).

  For example, the HGW 10 of the user A's home uses “Call-ID”, “From (URI of its own device)” and “To (URI of the conference room server)” as call session information for communication established by SIP. Obtained by collecting information from the information contained on its own. Further, the HGW 10 of the user A's home generates a “departure / departure determination flag” indicating whether the SIP phone 30 is the calling side or the called side from information included in the communication established by the SIP. The HGW 10 stores the collected or acquired call session information “Call-ID, From (URI of the own device), To (URI of the conference room server)” and “departure / departure determination flag” in association with each other. The HGW 10 transmits “control session information” included in the call destination change instruction transmitted from the session management server 100 and a connection completion notification to the session management server. Depending on whether or not the control session information received from each HGW 10 in S118 matches the control session information transmitted to each HGW 10 in step S111 or step S112, a call destination is sent to the conference room server in step S111 or step S112. It can be determined whether or not it is a connection completion notification from the HGW instructed to change. In addition, the above-described processing is also performed on the HGW of user B's home, and the “control session information” included in the call destination change instruction transmitted from the session management server 100 and the collected “call session information (call session) Information (B) "is transmitted to the session management server 100 together with the connection completion notification. Note that SIP communication between the HGW 10 of the user A and the conference room server 300 and between the HGW 10 of the user B home and the conference room server 300 are transmitted. Since SIP communication is SIP communication connected separately, the “Call-ID” acquired here is different.

  Further, for the conference room server 300, call session information is acquired and stored for each of the SIP communication with the HGW 10 at the user A home and the SIP communication with the HGW 10 at the user B home. That is, the conference room server 300 associates the collected or acquired call session information “Call-ID, From (URI of the own device), To (URI of the HGW of the user A home)” with the “departure / arrival determination flag”. Store. Furthermore, the conference room server 300 associates the collected or acquired call session information “Call-ID, From (URI of the own device), To (URI of the HGW of the user B home)” with the “departure / departure determination flag”. Store. Note that the call session information collection or acquisition method here is the same as in step S5, and thus the various methods described in step S5 can be applied.

  Returning to FIG. 22, the session management server 100 (conference room related control unit 133) that received the connection completion notification from each of the HGW 10 at the user A home, the HGW 10 at the user B home, and the conference room server 300 received from the HGW 10. “Control session information” and “call session information” are associated with each other, and a group ID is assigned and stored (step S119). At this time, for the old call session information, a call end time indicating that the call has ended is set. For example, the session management server 100 (conference room related control unit 133) identifies “group ID” associated with “control session information” received from the HGW of the user A's home from the control session management table. Then, the session management server 100 (conference room related control unit 133) associates the “control session information” and the “call session information” received from the HGW 10 of the user A's home with the identified “group ID”. Information is stored in the control session management table 123 as a new record. The session management server 100 (conference room related control unit 133) performs the above-described process for each of the arrivals and departures between the user A's home and the HGW and the arrivals and departures between the user B's home and the HGW. In the management table 123, four records are newly stored (third to sixth record names from the top in FIG. 5). In addition, since the outgoing / incoming (calling side and called side) are connected by the same SIP communication, the control session information and the call session information have the same value. Here, an example in which a new record is added has been described. However, the present invention is not limited to this, and old information having the same “control session information” may be overwritten.

  Subsequently, the session management server 100 (conference room related control unit 133) specifies the “conference room ID” corresponding to the “group ID” specified in step S119 from the conference room correspondence management table 126 (step S120). Along with “call session information (call session information (A), call session information (B))” of the apparatus, the conference room server 300 is notified to request connection of a voice bridge (step S121). Then, the conference room server 300 (voice bridge control unit 332), the voice bridge between the HGWs 10 specified by the “conference room ID” and the “call session information” received from the session management server 100 (two-party voice bridge). (Step S122), the two-way voice bridge start completion notification is notified to the session management server 100 (step S123). At this time, the conference room server 300 receives the “conference room ID” received from the session management server 100, “call session information (A) received from the HGW of the user A home”, and “HGW of the user B home”. “call session information (B)” and the like are associated and stored in the conference session information management table 322.

  Then, the 3PCC server transmits a connection instruction (third party call instruction) to the conference room server and the HGW of the user C home, and the conference room server 300 and the HGW 10 of the user C home (SIP phone 30) communicate with each other. The conference room server 300 and the SIP phone 30 of the user C's home are connected by telephone communication (step S125). The third party call is a connection between the terminal and the terminal by operating from another third device. Here, the session management server 100 is connected to the conference room server 300 and the SIP phone 30 of the user C's home. Is transmitted to the 3PCC server. In other words, the 3PCC server, which is different from both the conference room server 300 and the SIP phone 30 of the user C's home, which are call connection targets, connects the conference room server 300 and the SIP phone 30 of the user C's home by phone. The call connection method of the 3PCC server can use a general method of a third-party call. To explain briefly, first, the 3PCC server transmits INVITE to the conference room server and transmits 200V (conference room server's call). When receiving (SDP), ACK is returned to the conference room server 300. When the conference room server 300 responds in this way, the 3PCC server transmits an INVITE to the SIP phone 30 of the user C home and receives 200 OK (SDP of the SIP phone 30 of the user C home). ACK is returned to the SIP phone 30 of C home. As a result of the 3PCC server transmitting the SDP of the SIP phone 30 of the user C home to the conference room server 300 and the SDP of the conference room server 300 to the SIP phone 30 of the user C home, the conference room server 300 and SIP phone 30 of user C's home are connected. There are other methods using REFER and the like.

  Then, the conference room server 300 (voice bridge control unit 332) receives “Call-ID”, “From (URI of its own device)” and “To (URI of the conference room server)” as call session information (C). It is acquired by collecting it from information included in communication established by SIP, and transmitted to the session management server 100 (step S126). At this time, the ID notified in step S124 (ID indicating that the call has started based on the request in step S124) is also transmitted. The session management server 100 determines whether the received ID is a connection completion notification transmitted from the connection target of the connection instruction transmitted in step S124 based on whether or not the received ID matches the ID issued in step S124. can do. Note that the call session information collection or acquisition method here is the same as in step S5, and thus the various methods described in step S5 can be applied.

  On the other hand, the HGW 10 of the user C's home acquires call session information (C) that uniquely identifies the communication established by SIP and the arrival / departure determination flag, and information that uniquely identifies the subordinate SIP phone 30. A certain SIP phone ID is collected from information included in the SIP communication (step S127). Further, the HGW 10 of the user C's home specifies the information display terminal 20 that is used in combination with the SIP phone 30 that has established communication by SIP (step S128). Then, the HGW 10 of the user C home issues a redirect instruction for instructing the specified information display terminal 20 to change the access destination to the URL of the session management server 100 together with the call session information and the like (step S129). . At this time, the ID notified in step S124 (ID indicating that the call has started based on the request in step S124) is also transmitted. Further, the HGW 10 of the user C home includes the URL of the HGW 10 of the user C home in the redirect instruction. The session management server 100 determines whether the received ID is a connection completion notification transmitted from the connection target of the connection instruction transmitted in step S124 based on whether or not the received ID matches the ID issued in step S124. can do. Note that the call session information collection or acquisition method here is the same as in step S5, and thus the various methods described in step S5 can be applied.

  In this way, the session management server 100 (conference room related control unit 133) that has received the call session information (C) from the conference room server 300 verifies the call session information (C) and the like in the same manner as in step S10. After confirming that the call session information (C) is authentic information, as shown in step S11, the call session information (C), the URL of the HGW 10 and the start time as the call information are set in the control session. It is stored in the management table 123, the control session information is paid out, and the call session information (C) “Call-ID, From (URI of its own device), To (URI of the conference room server) is associated with the paid out control session information. ), HGW side record “departure / departure flag (departure)” and call session information (C) A session management table for control of two records including a conference room server side record of “Call-ID, From (URI of own device), To (URI of conference room server), and arrival / departure flag (arrival)”. 123 (step S130). Note that the above-described processing may be executed using call session information (C) from the information display terminal 20 of the user C's home. Subsequently, the session management server 100 (conference room related control unit 133) determines the group ID (group3) of the record having the same “To (URI of conference room server)” in the call session information (C) of the two added records. The user C is added to the same group as the users A and B by additionally storing them in the group ID of the two added records (step S131).

  Then, the session management server 100 (conference room related control unit 133) specifies the “conference room ID” corresponding to the “group ID” additionally stored in step S131 from the conference room correspondence management table 126, and the user C's house The “call session information (call session information (C))” and “conference room ID” are requested to the conference room server 300 to connect to the voice bridge (step S132).

  Then, the conference room server 300 (voice bridge control unit 332) similarly receives the “call” of the user C's home received in the conference session information management table 322 with the same “conference room ID” received from the session management server 100. The user C is added to the voice bridges of the users A and B by additionally storing the session information (call session information (C)) (step S133). The conference room server 300 uses the received “conference room ID” when the conference room ID matching the “conference room ID” received from the session management server 100 does not exist in the conference session information management table 322. Using the “call session information (call session information (C))” of the person C's house, a record in which these are associated is additionally stored in the conference session information management table 322. In this way, even if user A and user B are not calling first, user A and user B can enter the conference room after user C's home is connected first. Thus, the connection between the three parties can be performed. Then, the conference room server 300 (voice bridge control unit 332) notifies the session management server 100 of the completion notification together with the conference room ID that started the three-party voice bridge (step S134). As a result, the SIP phone 30 at user A's home, the SIP phone 30 at user B's home, and the SIP phone 30 at user C's home are connected via a conference room server 300 to a three-party voice bridge connection (step S135). ).

  Thereafter, the session management server 100 performs the same processing as steps S12 to S35, and displays a service providing screen on the information display terminal 20 of the user C's home. Specifically, when the session management server 100 receives call session information or the like transmitted from the information display terminal 20, the session management server 100 verifies the call session information (C) or the like (step S150). Subsequently, when the session management server 100 confirms that the call session information (C) or the like is authentic information as a result of the verification in step S150, the call session information (C) or the like, the URL of the HGW 10, and the call information Is stored in the control session management table, the control session information is paid out, and the issued control session information is stored in the control session management table 123 (step S151).

  Then, the session management server 100 uses the user contract service management table 121 to identify the service ID used between the devices where the three-party voice bridge is started (the SIP font at the user A's SIP font user B's home). The service ID is confirmed (step S152). Further, the session management server 100 generates a control page (step S153).

  Subsequently, the session management server 100 sends a connection destination monitoring function, control session information paid out in step S151, a control page generated in step S153, and a control page generated in step S152 to the information display terminal of user C's home. The acquired service ID currently used is transmitted (step S154).

  Then, the information display terminal 20 of the user C's home displays the control page transmitted from the session management server 100 from the web browser (step S155). Then, the connection destination monitoring function installed in the information display terminal of the user C's home in the same manner as in step S15 automatically transmits the control session information transmitted in step S154 when the control page is displayed. The service ID and the service start request are transmitted to the session management server 100 (step S157).

  Upon receiving this service start request, the session management server 100 confirms that the control session information transmitted from the information display terminal of the user C's home is registered in the control session management table 123 (step S158), the record associated with the control session information transmitted from the information display terminal 20 of the user C's home is identified from the arrival / departure association ID table 124, and the arrival / departure string stored in the identified record The attachment ID and the pseudonym ID are acquired from the departure / arrival association ID table 124 (step S159), and the certificate is added to the URL of the service providing server 200, the departure / arrival association ID, the pseudonym ID, and the arrival / departure determination flag. Then, the information is transmitted to the connection destination monitoring function of the information display terminal 20 at user C's home (step S160).

  On the other hand, the information display terminal 20 of the user C's home is connected to the URL transmitted from the session management server 100, and provides the service ID and pseudonym ID and the arrival / departure determination flag transmitted from the session management server 100. It transmits to the server 200 (step S161).

  Then, when the service providing server 200 (service providing control unit 232) receives the arrival / departure association ID, the pseudonym ID, and the arrival / departure determination flag transmitted from the information display terminal of the user C's home, the arrival / departure association ID, The pseudonym ID and the arrival / departure determination flag are verified based on the certificate added in step S160 (step S162). And if the service provision server 200 (service provision control part 232) confirms that the link ID between departure and arrival, kana ID, and the arrival / departure determination flag are authentic information as a result of the verification in step S162, the link between departure and arrival is indicated. Then, the Web session information is paid out as information to be given to the Web communication performed by the information display terminal of the user C's home that has transmitted the kana ID and the arrival / departure determination flag, and is stored in the Web session information management table 221 (step S163). Subsequently, the service providing server 200 (the service providing control unit 232) specifies a pseudonym ID that matches the received arrival / departure linking ID from the Web session information management table 2221, and specifies a call destination by the specified pseudonym ID. Then, a service providing screen is generated (step S164), and the generated service providing screen is transmitted to the information display terminal 20 of the user C's home together with the Web session information paid out in step S163 (step S165).

  Then, a service provision screen is displayed on the Web browser of the information display terminal 20 of the user C's home (step S166).

  As a result, the session management server 100 can control the information display terminal on the receiving side simultaneously (or immediately) with the control of the information display terminal on the calling side in response to the service start request. Then, both of the information display terminals on the receiving side immediately use the service (step S167).

  For example, the information display terminal of the user's home A uploads image data to the service providing server 200 through Web communication to which the paid-out Web session information is assigned. Then, the information display terminals 20 of the user B home and the user C home, which are connected to the user A home by a voice bridge and assigned the same arrival / departure linking ID, are similarly delivered Web session information. It is assumed that the service providing server 200 is accessed by Web communication to which is added. Then, the service providing server 200 controls the service so as to transmit the image data to the information display terminals 20 of the user B home and the user C home, so that the image uploaded from the information display terminal 20 of the user home A Data is transmitted to the information display terminals 20 of the user B home and the user C home. As a result, the information display terminal 20 of the user B home and the user C home can download (receive) the image data uploaded from the information display terminal 20 of the user home A and display it on the output unit.

  As described above, according to the first embodiment, 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. become. For example, a plurality of user homes can be connected to each other in a temporary communication relationship using a simple interface called a SIP phone.

  As described above, in the service providing system according to the first embodiment, the session management server 100 issues an arrival / departure linking ID for realizing service provision based on a temporary communication relationship established by SIP, When a delivery request is accepted, data delivery is controlled after confirming that the user who has requested the delivery request is busy. For this reason, a user who uses the SIP phone 30 and the information display terminal 20 as a pair can use the Web service in cooperation with the other party while making a call, for example. It becomes possible to exchange data easily by extending the number of times. In addition, if the user trusts the session management server 100, the user can exchange data with peace of mind.

  By the way, in the first embodiment, after the two parties (user A and user B) are voice bridged, they are connected to the conference room server 300, and a new user (user C) is connected via the conference room server 300. However, the present invention is not limited to this, and after the user A connects to the conference room server 300, the user B and the user C connect to the conference room server 300. Even in a connection form in which connections are made, a three-party connection can be made.

(Direct connection method)
Specifically, a user at user home A who is connected by phone call directly selects a conference room number (conference room ID) for connection between the three using the SIP phone 30, and a conference of the selected conference room number A three-party connection can also be initiated using a room.

  For example, as shown in FIG. 25, between the SIP phone 30 of user A's home and the session management server 100, and between the conference room server 300 and the session management server 100, steps S1 to S27 in FIG. (Step S501), the service providing server 200 transmits a conference room number selection screen (URL) to the information display terminal 20 of the user A's home (step S502).

  Thereafter, the information display terminal 20 of the user A's home displays the conference room number selection screen (URL) transmitted from the service providing server 200 on a display or the like, and is selected when receiving the conference room number input from the user. The conference room number is transmitted to the session management server 100 (steps S503 to S505). The session management server 100 refers to the conference room correspondence management table 126 using the conference room ID selected by the user (“5” in step S503) as a key, and is associated with the conference room ID selected by the user. It is checked whether or not a group ID exists (step S506). Subsequently, when the group ID associated with the conference room ID selected by the user exists in the conference room correspondence management table 126, the session management server 100 uses the group ID as a key to control the session management table for control. 123, it is checked whether or not there is control session information associated with the group ID (step S507).

  At this time, if there is control session information associated with the group ID, the session management server 100 (conference room related control unit 133) uses the control session information as a key to store the arrival / departure association ID table 124. Search and obtain a pair of arrival / departure linking ID and service ID. Then, the session management server 100 searches the arrival / departure association ID table 124 using the service ID acquired at this time as a key. If there is a service ID whose status is in use with the same service ID, the session management server 100 is in use. Overwrite the arrival / departure linking ID associated with the service ID with the previously obtained departure / arrival linking ID. By doing in this way, it becomes possible for the user of the same group ID to use the same link ID between arrival and departure when using the same service. On the other hand, when there is no control session information associated with the group ID, the session management server 100 issues a new group ID to the conference room ID in the conference room correspondence management table 126 and at the same time, the issued group ID. Is also set in the control session management table 123.

  Then, the service providing server 200 transmits to the conference room server a voice bridge connection request including the call session information received from the information display terminal of the user A's home, the pseudonym ID, the arrival / departure linking ID, and the conference room number ( Step S508).

  The conference room server 300 (voice bridge controller 332) voice-bridges the received call session information call to the conference room number (conference room ID) (step S509). At this time, the conference room status specified by the conference room number is in use. Then, the conference room server 300 transmits the kana ID and the arrival / departure association ID received from the information display terminal 20 of the user A's home to the session management server 100 as a response of S509 (step S510).

  Then, the session management server 100 transmits to the conference room server 300 the kana ID and the arrival / departure linking ID received from the information display terminal 20 of the user A's house together with the processing result of step S510 (step S511). The conference room server 300 notifies the service providing server 200 of a voice bridge completion notification (step S512). Then, the service providing server 200 transmits the connected conference room screen to the information display terminal (steps S513 and S514), and uniquely distinguishes SIP voice communication and web communication into call session information and web session information. As a result, the user A's home and the conference room server are communicably connected.

  Thereafter, the processes from step S501 to step S514 are performed between the user B home and the session management server 100, between the session management server 100 and the conference room server, and between the service providing server 200 and the user B home. It is executed (step S515). That is, steps S1 to S27 in FIG. 20 are executed between the SIP phone 30 of the user B's home and the session management server 100, and between the conference room server 300 and the session management server 100. The home information display terminal accepts the input of the conference room number on the conference room number selection screen (URL) transmitted from the service providing server 200. Thereafter, the session management server 100 executes a group ID existence check and a control session information existence check, and the conference room server 300 connects the designated conference room ID and the voice bridge. That is, when the user B's home receives input of the same conference room ID as the conference room ID that is voice-bridged with the user A's home, the same group ID is assigned to the user A home and the user B home. . Then, the SIP phone 30 and the information display terminal 20 in the user B home are further connected to the conference room where the SIP phone 30 and the information display terminal 20 in the user A home are voice-bridged. Thus, user A's home (SIP phone or information display terminal) and user B's home (SIP phone or information display terminal) are connected via the conference room server 300.

  Similarly, steps S501 to S514 are also performed between the user C home and the session management server 100, between the session management server 100 and the conference room server 300, and between the service providing server 200 and the user C home. Processing is executed (step S516). That is, steps S1 to S27 in FIG. 20 are executed between the SIP phone of user C's home and session management server 100, and between conference room server 300 and session management server 100, and user C's home The information display terminal 20 accepts the input of the conference room number on the conference room number selection screen (URL) transmitted from the service providing server 200. Thereafter, the session management server 100 executes a group ID existence check and a control session information existence check, and the conference room server 300 connects the designated conference room ID and the voice bridge. That is, when the input of the same conference room ID as the conference room ID that is voice-bridged with the user A home and the user B home is received at the user C home, the user A home, the user B home, and the user C home. Are assigned the same group ID. Then, the SIP phone 30 and the information display terminal 20 in the user A home and the user B home are further connected to the conference room where the SIP phone in the user C home and the information display terminal 20 are voice bridged. . In this way, user A's home (SIP phone 30 and information display terminal 20), user B's home (SIP phone 30 and information display terminal 20), and user C's home (SIP phone 30 and information display terminal 20). Terminal 20) is connected via conference room server 300. As a result of the above processing, the same processing as step S167 in FIG. 24 can be executed between user A's home, user B's home, and user C's home (step S517).
