JP4864999B2 - Caller information notification request service system, session control server, call control method, and program - Google Patents

Description

  The present invention relates to a caller information notification request service system, a session control server, a call control method, and a program to be executed by a server.

  The outgoing phone number notification request service is the name of “number request” in the line exchange bearer service (voice, 3.1 kHz audio) of the INS Net (registered trademark) service of Nippon Telegraph and Telephone Corporation and “Hikari Telephone”. (See Non-Patent Literature 1 to Non-Patent Literature 4).

  The calling phone number notification request service function allows the calling phone number information to be stored on the basis of the contract between the called user and the service provider when the calling phone user explicitly rejects the calling phone number notification and places a call. The incoming call is not sent to the receiving user's telephone, but the network responds (announces) and prompts the calling user to make a call by notifying the outgoing telephone number.

  The above proxy response is for example, “This is“ ○○○-△△△-□□□□ (incoming phone number) ”to a user who has made a call without notifying the outgoing phone number. Give your phone number a call, such as dialing with 186 in front of the number. " In this case, the ring tone of the receiving user's telephone does not sound. If the incoming call is rejected, this is notified to the user on the calling side.

  FIG. 19 is a diagram for explaining a calling telephone number notification request service. As shown in FIG. 19, a public switched network (PSTN) 60 is provided with exchanges 610 and 620 and a voice response device (Interactive Voice Response: IVR) 630. Here, it is assumed that the calling-side telephone 641 is connected to the exchange 610 and the incoming-side telephone 642 is connected to the exchange 620.

  The operation of the communication system shown in FIG. 19 will be briefly described. When the user of the telephone 641 makes a call to the telephone 642 with the setting not to notify the calling telephone number, the telephone 641 transmits a connection request signal, which is a signal for requesting connection to the partner terminal, to the exchange 610 (step 651). ). The exchange 610 receives the connection request signal from the telephone 641, and transmits the connection request signal to the IVR 630 via the exchange 620 when the information to notify the calling telephone number is not included in the connection request signal (step 652). 653). When the IVR 630 receives the connection request signal from the exchange 620, the IVR 630 transmits a voice message to the exchange 620 requesting notification of the calling telephone number (step 654). The exchange 620 transmits the voice message received from the IVR 630 to the telephone set 641 via the exchange 610 (steps 655 and 656).

  The calling phone number notification request service function is based on the premise that the user on the receiving side has signed a “calling phone number notification service” contract with a service provider in advance.

(First embodiment)
The configuration of the communication system according to this embodiment will be described. FIG. 1 is a block diagram illustrating a configuration example of a communication system according to the present embodiment.

  The communication system of the present embodiment includes a session control server (hereinafter referred to as a SIP server) 20 and a media server (hereinafter referred to as MS) 30 as call control means. The SIP server 20 and the MS 30 are connected via a network 10 such as an IP network. The SIP server 20 is connected to the terminal 41 and the terminal 42 via the network 10. The connection between each of the terminals 41 and 42 and the SIP server 20 may be made via a communication device such as a router or a terminal adapter, and the illustration of these communication devices is omitted.

  The configuration of the SIP server 20 shown in FIG. 1 will be described. FIG. 2 is a block diagram showing a configuration example of the SIP server shown in FIG.

  As illustrated in FIG. 2, the SIP server 20 includes a storage unit 203 and a control unit 201 including a call control unit 211 and a determination unit 212. The control unit 201 is provided with a CPU (Central Processing Unit) (not shown) that executes predetermined processing according to a program, and a memory (not shown) for storing the program. As the CPU executes the program, each of the call control unit 211 and the determination unit 212 is virtually configured in the SIP server.

  Note that the call control unit 211 may be a dedicated circuit, and the determination unit 212 may be configured by the CPU executing a program. Each of the call control unit 211 and the determination unit 212 conforms to the operation of each unit. A dedicated circuit may be provided.

  In the storage unit 203, terminal registration information, which is information about the service requested by the contractor, is registered for each terminal. FIG. 3 is a table for explaining the terminal registration information.

  In the table shown in FIG. 3A, the contractor telephone number, the contractor terminal capability, the caller information requested by the contractor, And a request identifier for specifying the service requested by the contractor. As shown in FIG. 3A, the caller information includes a calling number, caller location information, caller video information, caller contractor information, and the like. The caller video information is a video for authenticating the caller, and the caller contractor information is the name of the caller. The video for authenticating the caller may be a real-time video that is a video of the current state of the caller, or may be a character video such as an “avatar” used in the Internet community.

  The caller information corresponds to the request identifier. For example, in the first row of the table shown in FIG. 3A, “calling phone number”, which means a calling phone number, corresponds to the request identifier “SID1”. Details of the request identifier will be described later. Each of the UID and the contractor telephone number corresponds to a terminal identifier that is an identifier that differs for each terminal. Information registered as sender information for each contractor ID is referred to as setting information.

  In FIG. 3A, the caller identifier, which is an identifier for specifying the caller, is described in the case of a contractor telephone number, but the caller identifier may be other information. FIG. 3B is a table showing an example of a caller identifier. As shown in FIG. 3B, the caller identifier is not limited to the subscriber telephone number, but may be TEL_URI (Uniform Resource Identifier) or SIP_URI. In the following description, the caller identifier is a contractor telephone number.

  The terminal registration information stored in the storage unit 203 only needs to include at least a terminal identifier, setting information, and a request identifier. A specific example will be described with reference to the table shown in FIG. 3. In the case of a terminal having a terminal identifier UID1, terminal registration information in which UID1 or 03-1111-1111, a calling telephone number as setting information, and SID1 as a request identifier are paired. Is registered in the storage unit 203. Further, as shown in FIG. 3, in the case of the terminal identifier UID2, two pieces of caller information, that is, a caller telephone number and caller location information are registered in the setting information, and a plurality of pieces of caller information are set in one terminal. May be registered.

  The call control unit 211 performs the following operation in addition to normal call control processing. When a call setting request signal is received, which includes information on the telephone numbers of the calling terminal and the receiving terminal and is a signal requesting call setting, the call setting request signal is passed to the determination unit 212. When the call setting request signal is received from the determination unit 212, the call setting request signal is transmitted to the destination. On the other hand, when a request identifier is received from the determination unit 212, a call setting request signal including the request identifier is transmitted to the MS 30. When a response signal for the call setup request signal is received from the MS 30, a response signal for establishing a communication path between the MS 30 and the originating terminal is transmitted to the originating terminal. The sound source information specified by the request identifier corresponds to a message for notifying the caller. As will be described later, the message for notifying the caller is not limited to the voice message based on the sound source information but may be an image message.

  When receiving the call setting request signal from the call control unit 211, the determination unit 212 reads the setting information from the terminal registration information of the receiving terminal stored in the storage unit 203. Subsequently, it is determined whether or not the read setting information is included in the call setting request signal. When the setting information is not included in the call setting request signal, the call control unit 211 is notified of a request identifier corresponding to the setting information. On the other hand, when the setting information is included in the call setting request signal, the call control signal received from the call control unit 211 is returned to the call control unit 211 as it is. The telephone number is one of terminal identifiers that are different for each terminal.

  Next, the configuration of the MS 30 will be described. FIG. 4 is a block diagram showing a configuration example of the MS shown in FIG.

  As illustrated in FIG. 4, the MS 30 includes a storage unit 303 and a control unit 301. The control unit 301 is provided with a CPU (not shown) that executes predetermined processing according to a program and a memory (not shown) for storing the program.

  In the storage unit 303, sound source information and a sound source corresponding to the sound source type are registered. FIG. 5 is a table for explaining the sound source information.

  In the table shown in FIG. 5, the sound source type name and the description of the sound source are described in correspondence with different sound source IDs (hereinafter referred to as SID) for each sound source type. The sound source ID is the same as the request identifier shown in FIG. 3, and for the sake of explanation, only the way of calling is changed between FIG. 3 and FIG. Therefore, the “calling telephone number” in the setting information shown in FIG. 3 corresponds to the “number request” of the sound source type in FIG. 4, and the “sender location information” corresponds to the “location request”. “Sender video information” corresponds to “video request”, and “sender contractor information” corresponds to “name request”.

  As the sound source information stored in the storage unit 303, at least the SID and the sound source corresponding to the SID are sufficient. An example of a sound source will be described. As a sound source of the guidance requesting notification of the phone number, “This is a number request service. Excuse me, please dial 186 in front of the phone number and dial your phone number.” "This is a number request service. Excuse me, please cancel the phone number non-notification setting and try again." The sound source may repeat this message two or more times.

  When receiving a call setting request signal from the SIP server 20, the control unit 301 reads a request identifier from the call setting request signal and reads a sound source corresponding to the request identifier from the storage unit 303. Then, a response signal to the call setting request signal is transmitted to the caller's terminal to establish a speech path, and then the read voice message of the sound source is transmitted to the caller's terminal. Hereinafter, this voice message is referred to as a guidance response call.

  Next, the configuration of the terminals 41 and 42 will be described. Since the terminals 41 and 42 have the same configuration, the configuration of the terminal 41 will be described here as a representative of these terminals.

  6 is a block diagram showing an example of the configuration of the terminal shown in FIG. As illustrated in FIG. 6, the terminal 41 includes a storage unit 413 that stores data received from the outside, a display unit 415 that displays caller information, a terminal control unit 411 that controls each unit, and a user And an operation unit 417 for inputting an instruction. The terminal control unit 411 is provided with a CPU (not shown) that executes predetermined processing according to a program and a memory (not shown) for storing the program.

  When the terminal 41 has the “number display” function shown in FIG. 3 as the contractor terminal capability, the terminal control unit 411 reads out the telephone number of the calling terminal from the call setting request signal and displays it on the display unit 415. Let

  When the terminal 41 has the function of “caller contract terminal position information display”, the terminal control unit 411 reads the caller position information of the caller terminal from the call setting request signal and causes the display unit 415 to display it. The caller location information is a registered location such as the caller's address if it is difficult for the terminal on the call setup request signal sending side to move. As a terminal that is difficult to move, for example, there is a desktop personal computer having a function of converting voice data into packet data. However, when the terminal on the transmission side is a mobile body (for example, a mobile phone) having a wireless communication function, the caller location information is location information specified by GPS (Global Positioning System) or a radio base station.

  When the terminal 41 has the function of “video display”, the terminal control unit 411 reads the caller video information from the call setting request signal and causes the display unit 415 to display it. In this case, a camera is provided in the terminal on the call setup request signal transmission side, the camera captures a real-time video of the caller, and the transmission side terminal transmits the captured image data in the call setup request signal.

  When the terminal 41 has the function of “name display”, the terminal control unit 411 reads the name of the caller from the call setting request signal and causes the display unit 415 to display it.

  The operation unit 417 includes key units (not shown) such as numeric keys for inputting telephone numbers, character input keys for character input, on-hook keys, off-hook keys, and various command input keys, and voice output. A speaker (not shown) and a microphone (not shown) for voice input are provided.

  Here, operations of the operation unit 417 and the terminal control unit 411 when the terminal 41 is the transmission side will be described. By operating the operation unit 417, the user can set whether or not to notify the other party of the telephone about each of the calling number, location information, his real-time video, and his name. When the user operates the operation unit 417 to set non-notification and then inputs the telephone number of the other party, the terminal control unit 411 sends the call setting request signal excluding the information that is the target of non-notification setting to the other party. Send to the destination terminal.

  On the contrary, the case where the terminal 41 is the receiving side will be described.

  In order to use the caller information notification request service, the user of the terminal 41 concludes a contract with the service provider to receive the caller information notification request service. When a user subscribes to a service provider at the time of contracting which of the caller information such as the calling number, location information, caller video, and caller name is registered in the setting information, the service is provided. Terminal registration information including setting information is registered in the SIP server 20 by a company administrator.

  Here, a case where the user registers the setting information by operating the terminal 41 will be briefly described. When the user operates the operation unit 417 of the terminal 41 and inputs at least one of the calling telephone number, the location information of the caller, the video of the caller, and the name of the caller as setting information, the terminal control unit of the terminal 41 411 transmits to the SIP server 20 a setting information registration request signal including the input setting information and information for requesting registration of the setting information. When receiving the setting information registration request signal from the terminal 41, the determination unit 212 of the control unit 201 of the SIP server 20 receives, as terminal registration information of the terminal 41, a request identifier corresponding to the setting information included in the setting information registration request signal and the terminal 41 terminal identifiers are stored in the storage unit 203 as a set.

  As another registration method, the user operates the operation unit 417 after the contract, and activates the registration of the caller information in the setting information by the customer control of the caller information request service, or does not register in the setting information. Activation may be performed. Further, the service provider may charge the caller for the guidance response call. In this case, the effect of preventing the caller from making a call without revealing his / her information is improved.

  An operation procedure of the communication system according to the present embodiment will be described. First, there is a case where no setting information is registered for the terminal 42. FIG. 7 is a sequence diagram showing an operation procedure when setting information is not registered in the terminal on the receiving side in the communication system of the present embodiment.

  After the user of the terminal 41 operates the terminal 41 to set the caller information to non notification, the terminal 41 enters the telephone number of the terminal 42 and makes a call to the terminal 42. A request signal (INVITE) is transmitted to the SIP server 20 (step 1001).

  When the SIP server 20 receives a call setting request signal addressed to the terminal 42 from the terminal 41, the SIP server 20 recognizes that the call setting request signal is set not to be notified, and checks the terminal registration information of the terminal 42 in the storage unit 203. When it is confirmed that the setting information is not registered in the terminal registration information, a call setting request signal is transmitted to the terminal 42 (step 1002), and a provisional response signal indicating that the calling process is being performed is transmitted to the terminal 41. . When the terminal 42 receives the call setting request signal from the SIP server 20, the terminal 42 returns a provisional response signal to the SIP server 20, and when the user goes off-hook, transmits a response signal (200 OK) to the SIP server 20 (step 1003). When the SIP server 20 receives the response signal from the terminal 42, the SIP server 20 transmits the response signal to the terminal 41 (step 1004) and transmits an acknowledgment signal (ACK) to the terminal 42. Upon receiving the response signal from the SIP server 20, the terminal 41 transmits an acknowledgment signal to the terminal 42, and a communication path is established between the terminal 41 and the terminal 42 (step 1005).

  Next, an operation when a number request for requesting a calling telephone number is set in the terminal 42 will be described. FIG. 8 is a sequence diagram showing an operation procedure when a number request is set in the terminal on the receiving side in the communication system of the present embodiment.

  After the user of the terminal 41 operates the terminal 41 to set the caller information to non notification, the terminal 41 enters the telephone number of the terminal 42 and makes a call to the terminal 42. A request signal is transmitted to the SIP server 20 (step 1101).

  When the SIP server 20 receives a call setting request signal addressed to the terminal 42 from the terminal 41, the SIP server 20 transmits a provisional response signal to the terminal 41, recognizes that the call setting request signal is not notified, and sets the terminal 42. Terminal registration information is checked in the storage unit 203. When recognizing that the calling telephone number is registered in the setting information of the terminal registration information, the request identifier SID1 is read and a call setting request signal including SID1 is transmitted to the MS 30 (step 1102).

  When receiving the call setup request signal from the SIP server 20, the MS 30 transmits a response signal to the SIP server 20 (step 1103). Further, SID1 included in the call setting request signal is read, and a voice message corresponding to SID1 is read from the storage unit 303. When the SIP server 20 receives the response signal from the MS 30, the SIP server 20 transmits the response signal to the terminal 41 (step 1104), and transmits the confirmation response signal to the MS 30 (step 1105).

  When receiving the response signal from the SIP server 20, the terminal 41 transmits an acknowledgment signal to the MS 30, and a communication path is established between the terminal 41 and the MS 30 (step 1106). When the communication path is established between these devices, the MS 30 transmits the voice message read from the storage unit 303 to the terminal 41 (step 1107). When the terminal 41 receives a voice message from the MS 30, the speaker outputs a voice message “This is a number request service. Excuse me, please cancel the phone number non-notification setting and try again”.

  Next, an operation when a location request for requesting caller location information is set in the terminal 42 will be described. FIG. 9 is a sequence diagram illustrating an operation procedure when a location request is set in a terminal on the receiving side in the communication system according to the present embodiment.

  After the user of the terminal 41 operates the terminal 41 to set the caller information to non notification, the terminal 41 enters the telephone number of the terminal 42 and makes a call to the terminal 42. A request signal is transmitted to the SIP server 20 (step 1201).

  When the SIP server 20 receives a call setting request signal addressed to the terminal 42 from the terminal 41, the SIP server 20 transmits a provisional response signal to the terminal 41, recognizes that the call setting request signal is not notified, and sets the terminal 42. Terminal registration information is checked in the storage unit 203. When recognizing that the caller location information is registered in the setting information of the terminal registration information, the request identifier SID3 is read and a call setting request signal including SID3 is transmitted to the MS 30 (step 1202).

  When receiving the call setup request signal from the SIP server 20, the MS 30 transmits a response signal to the SIP server 20 (step 1203). Further, SID3 included in the call setting request signal is read, and a voice message corresponding to SID3 is read from the storage unit 303. When the SIP server 20 receives the response signal from the MS 30, the SIP server 20 transmits the response signal to the terminal 41 (step 1204), and transmits the confirmation response signal to the MS 30 (step 1205).

  When the terminal 41 receives the response signal from the SIP server 20, the terminal 41 transmits an acknowledgment signal to the MS 30, and a communication path is established between the terminal 41 and the MS 30 (step 1206). When the communication path is established between these devices, the MS 30 transmits the voice message read from the storage unit 303 to the terminal 41 (step 1207). When the terminal 41 receives the voice message from the MS 30, the speaker outputs a voice guidance “This is a location request service. Excuse me, please cancel the non-notification setting of the current position and try again”.

  Next, an operation when a video request for requesting sender video information is set in the terminal 42 will be described. FIG. 10 is a sequence diagram showing an operation procedure when a video request is set in the terminal on the receiving side in the communication system of the present embodiment.

  After the user of the terminal 41 operates the terminal 41 to set the caller information to non notification, the terminal 41 enters the telephone number of the terminal 42 and makes a call to the terminal 42. A request signal is transmitted to the SIP server 20 (step 1301).

  When the SIP server 20 receives a call setting request signal addressed to the terminal 42 from the terminal 41, the SIP server 20 transmits a provisional response signal to the terminal 41, recognizes that the call setting request signal is not notified, and sets the terminal 42. Terminal registration information is checked in the storage unit 203. When it is recognized that the sender video information is registered in the setting information of the terminal registration information, the request identifier SID4 is read and a call setting request signal including SID4 is transmitted to the MS 30 (step 1302).

  When receiving the call setup request signal from the SIP server 20, the MS 30 transmits a response signal to the SIP server 20 (step 1303). Further, SID4 included in the call setting request signal is read, and a voice message corresponding to SID4 is read from the storage unit 303. When the SIP server 20 receives the response signal from the MS 30, the SIP server 20 transmits the response signal to the terminal 41 (step 1304), and transmits the confirmation response signal to the MS 30 (step 1305).

  When the terminal 41 receives the response signal from the SIP server 20, the terminal 41 transmits an acknowledgment signal to the MS 30, and a communication path is established between the terminal 41 and the MS 30 (step 1306). When the communication path is established between these devices, the MS 30 transmits the voice message read from the storage unit 303 to the terminal 41 (step 1307). When the terminal 41 receives a voice message from the MS 30, a voice message “This is a video request service. Excuse me, please set the video transmission for the caller and try again.” To do.

  Next, an operation when a name request for requesting calling side contractor information is set in the terminal 42 will be described. FIG. 11 is a sequence diagram showing an operation procedure when a name request is set in the terminal on the receiving side in the communication system of the present embodiment.

  After the user of the terminal 41 operates the terminal 41 to set the caller information to non notification, the terminal 41 enters the telephone number of the terminal 42 and makes a call to the terminal 42. A request signal is transmitted to the SIP server 20 (step 1401).

  When the SIP server 20 receives a call setting request signal addressed to the terminal 42 from the terminal 41, the SIP server 20 transmits a provisional response signal to the terminal 41, recognizes that the call setting request signal is not notified, and sets the terminal 42. Terminal registration information is checked in the storage unit 203. When recognizing that the calling party contractor information is registered in the setting information of the terminal registration information, SID2 of the request identifier is read and a call setting request signal including SID2 is transmitted to the MS 30 (step 1402).

  When receiving the call setup request signal from the SIP server 20, the MS 30 transmits a response signal to the SIP server 20 (step 1403). Further, SID2 included in the call setting request signal is read, and a voice message corresponding to SID2 is read from the storage unit 303. When the SIP server 20 receives the response signal from the MS 30, the SIP server 20 transmits the response signal to the terminal 41 (step 1404), and transmits the confirmation response signal to the MS 30 (step 1405).

  When receiving the response signal from the SIP server 20, the terminal 41 transmits an acknowledgment signal to the MS 30, and a communication path is established between the terminal 41 and the MS 30 (step 1406). When the communication path is established between these devices, the MS 30 transmits the voice message read from the storage unit 303 to the terminal 41 (step 1407). When the terminal 41 receives a voice message from the MS 30, a guidance from the speaker is “This is a name request service. Excuse me, please cancel the caller's name non-notification setting and try again”. Output by voice.

  Here, a case of NGN (next generation network) which is a kind of network 10 will be described. NGN is being standardized by ITU-T (International Telecommunication Union Telecommunication Standardization Sector) and TTC (Information and Communication Technology Committee).

  In the NGN, there are two types of session control servers: a subscriber session control server (Subscriber Session Control Server: SSC) that accommodates subscribers and a relay session control server (Intermediate Session Control Server: ISC) that performs relay processing. When the network 10 is NGN, the SIP server 20 may be SSC or ISC.

  FIG. 12 is a block diagram showing a configuration example when the network of the communication system of the present embodiment is NGN.

  FIG. 12A shows a case where the SIP server 20 of this embodiment is an ISC 51. FIG. As illustrated in FIG. 12A, the terminal 41 is accommodated in the SSC 52, and the terminal 42 is accommodated in the SSC 53. Each of the SSCs 52 and 53 is connected via the ISC 51 and the NGN 50, and the ISC 51 is connected via the MS 30 and the NGN 50. Another server or router may be provided on the communication path between the ISC 51 and the MS 30.

  FIG. 12B shows a case where the SIP server 20 of this embodiment is an SSC 57. As shown in FIG. 12B, the terminal 41 is accommodated in the SSC 56, and the terminal 42 is accommodated in the SSC 57. Each of the SSCs 56 and 57 is connected to the ISC 55 via the NGN 50, and the SSC 57 is connected to the MS 30 via the NGN 50. Other servers and routers may be provided on the communication path between the SSC 57 and the MS 30. Corresponding to FIG. 1, FIG. 12B shows that the SSC 57 and the MS 30 are connected, but the SSC 56 is also connected to the MS 30 via the NGN 50.

  In the following description, the SIP server 20 is the ISC 51 shown in FIG. Since the description of the SSC 56 or SSC 57 shown in FIG. 12B is the same as that of the ISC 51, the detailed description thereof is omitted. In the following, the case of a calling telephone number as the caller information will be described, and the description of the case of the caller's location information and name will be omitted.

  In the communication protocol in NGN, whether or not the caller ID notification request service guidance is provided is provided in an extension header (P-Asserted) for caller ID notification / non notification control provided in the call setting request signal (INVITE). -Identity). Specifically, it is set to Display Name of sip: in the extension header. When the ISC 51 receives the call setting request signal, the determination unit 212 determines whether or not guidance is provided based on the “reason for caller ID non-notification” parameter.

  FIG. 13 is a table showing the relationship between the reason for notifying the caller ID and the provision of guidance. With reference to FIG. 13, the operation when the caller refuses to notify the telephone number will be briefly described. It is assumed that the user of the terminal 42 has been registered to receive the caller ID notification request service.

  When the user of the terminal 41 shown in FIG. 12A rejects the notification of the telephone number and makes a call to the terminal 42, as shown in FIG. 13, the display of sip: in the P-Asserted-Identity header in INVITE “Anonymous” is set in Name, and the terminal 41 transmits the INVITE to the ISC 51 via the SSC 52. When the ISC 51 recognizes that “anonymous” is set in sip: in the P-Asserted-Identity header of the received INVITE, the ISC 51 transfers this INVITE to the MS 30.

  When ISC51 receives a voice message from MS30, “This is a number request service. Excuse me, but please dial 186 before the phone number and notify your phone number.” This voice message is transmitted to the terminal 41 via the SSC 52. Note that this voice message may be repeated twice or more.

(Second Embodiment)
This embodiment is a case where the SIP server stores a message requesting the user to notify the other party of information related to himself / herself.

  The configuration of the SIP server in this embodiment will be described with reference to FIGS. The same components as those in the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and different points will be described in detail.

  In the storage unit 203 of the SIP server 20, in addition to the terminal registration information described in the first embodiment, sound source information stored in the storage unit 303 of the MS 30 is stored together with a request identifier. This sound source information corresponds to a voice message requesting that a caller is notified of information related to himself / herself.

  The call control unit 211 passes the received call setting request signal to the determining unit 212, and when receiving the call setting request signal from the determining unit 212, transmits the call setting request signal to the destination. On the other hand, when a voice message is received from the determination unit 212, the voice message is transmitted to the terminal on the caller side in order to notify the caller of this voice message.

  When receiving the call setting request signal from the call control unit 211, the determination unit 212 reads the setting information from the terminal registration information of the receiving terminal stored in the storage unit 203. Subsequently, it is determined whether or not the read setting information is included in the call setting request signal. When the setting information is not included in the call setting request signal, the request identifier corresponding to the setting information is specified by the terminal registration information, and the voice message of the request identifier is read from the storage unit 203. Then, the read voice message is transferred to the call control unit 211. On the other hand, when the setting information is included in the call setting request signal, the call control signal received from the call control unit 211 is directly returned to the call control unit 211.

  Next, an operation when a number request for requesting a calling telephone number is set in the terminal 42 will be described. FIG. 14 is a sequence diagram illustrating an operation procedure of the call control method according to the present embodiment. In the present embodiment, a case of a calling number is described as the caller information, and a description of the case of the caller's location information and name is omitted.

  After the user of the terminal 41 operates the terminal 41 to set the caller information to non notification, the terminal 41 enters the telephone number of the terminal 42 and makes a call to the terminal 42. A request signal is transmitted to the SIP server 20 (step 1151).

  When the SIP server 20 receives a call setting request signal addressed to the terminal 42 from the terminal 41, the SIP server 20 recognizes that the call setting request signal is set not to be notified, and checks the terminal registration information of the terminal 42 in the storage unit 203. When recognizing that the calling telephone number is registered in the setting information of the terminal registration information, the request identifier SID1 is read, and the voice message corresponding to SID1 is read from the storage unit 203. Then, the SIP server 20 transmits a response signal to the terminal 41 (step 1152).

  When receiving a response signal from the SIP server 20, the terminal 41 establishes a communication path between the terminal 41 and the SIP server 20 (step 1153). When the communication path is established between these devices, the SIP server 20 transmits the voice message read from the storage unit 203 to the terminal 41 (step 1154). When the terminal 41 receives a voice message from the SIP server 20, the speaker outputs a voice message "This is a number request service. Excuse me, please cancel the phone number non-notification setting and try again". To do.

  In the present embodiment, since an MS for storing a voice message is not necessary, the equipment cost for the entire communication system can be suppressed.

(Third embodiment)
In the present embodiment, a message is stored in the terminal requesting the caller to notify the other party of information related to himself / herself.

  The configuration of the SIP server and the terminal of this embodiment will be described with reference to FIGS. The same components as those in the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and different points will be mainly described.

  In the present embodiment, the sound source information stored in the storage unit 303 of the MS 30 is stored together with the request identifier in the storage unit 413 of the terminal 41 shown in FIG. This sound source information corresponds to a voice message requesting that a caller is notified of information related to himself / herself.

  When receiving a response signal including request identifier information from the SIP server 20, the terminal control unit 411 of the terminal 41 reads out a voice message corresponding to the request identifier included in the response signal from the storage unit 413 and transmits the voice message to the operation unit 417. Output to the speaker. When the message notified to the caller is an image message instead of a voice message, the terminal control unit 411 displays the message on the display unit 415.

  The call control unit 211 of the SIP server 20 passes the received call setting request signal to the determining unit 212, and when receiving the call setting request signal from the determining unit 212, transmits the call setting request signal to the destination. On the other hand, when a request identifier is received from the determination unit 212, a response signal including information on the request identifier is transmitted to the caller terminal in order to notify the caller of a voice message corresponding to the request identifier.

  When receiving the call setting request signal from the call control unit 211, the determination unit 212 reads the setting information from the terminal registration information of the receiving terminal stored in the storage unit 203. Subsequently, it is determined whether or not the read setting information is included in the call setting request signal. When the setting information is not included in the call setting request signal, the request identifier corresponding to the setting information is specified by the terminal registration information, and the request identifier is passed to the call control unit 211. On the other hand, when the setting information is included in the call setting request signal, the call control signal received from the call control unit 211 is returned to the call control unit 211 as it is.

  Next, an operation when a number request for requesting a calling telephone number is set in the terminal 42 will be described. FIG. 15 is a sequence diagram showing an operation procedure of the call control method according to this embodiment. In the present embodiment, a case of a calling number is described as the caller information, and a description of the case of the caller's location information and name is omitted.

  After the user of the terminal 41 operates the terminal 41 to set the caller information to non notification, the terminal 41 enters the telephone number of the terminal 42 and makes a call to the terminal 42. A request signal is transmitted to the SIP server 20 (step 1161).

  When the SIP server 20 receives a call setting request signal addressed to the terminal 42 from the terminal 41, the SIP server 20 recognizes that the call setting request signal is set not to be notified, and checks the terminal registration information of the terminal 42 in the storage unit 203. When recognizing that the calling number is registered in the setting information of the terminal registration information, SID1 of the request identifier is read and a response signal including SID1 is transmitted to the terminal 41 (step 1162). The response signal here is, for example, an error code “433 (Anonymity Disabled)”.

  When the terminal 41 receives the response signal from the SIP server 20, the terminal 41 reads out the voice message corresponding to the request identifier included in the response signal from the storage unit 413, and outputs the voice message to the speaker of the operation unit 417 (step 1163). A voice message “This is a number request service. Excuse me, please cancel the non-notification of phone number and try again” is output from the speaker.

  In this embodiment, it is not necessary to provide an MS for storing a voice message, and it is not necessary to store the voice message in the SIP server, so that the equipment cost for the entire communication system can be further suppressed.

(Fourth embodiment)
In this embodiment, the caller makes a call from a PSTN telephone. The configuration of the communication system according to this embodiment will be described. FIG. 16 is a block diagram illustrating a configuration example of a communication system according to the present embodiment. The description will focus on the differences from the configuration shown in FIG.

  As shown in FIG. 16, a PSTN 60 and a network 10 are connected, and a PSTN gateway (PSTNGW) 25 that performs communication protocol conversion is provided in the network 10. The PSTN 25 is connected to the SIP server 20. In FIG. 16, the PSTN 25 is connected to the SIP server 20 via a signal line, but other communication devices such as a router may be provided between them. A telephone 44 is connected to the PSTN 60 instead of the terminal 41 as a terminal on the caller side.

  Next, the operation of the communication system of this embodiment will be described. It is assumed that a number request is set in the terminal 42. FIG. 17 is a sequence diagram showing an operation procedure of the communication system of the present embodiment.

  After the user of the telephone set 44 operates the telephone set 44 to set the caller information to non notification, when the telephone number of the terminal 42 is entered and the terminal 42 is called, the telephone set 44 is set to non notification setting. A request signal is transmitted to the PSTN 60 (step 1501).

  An exchange (not shown) in the PSTN 60 transmits a call setting request signal received from the telephone 44 to the PSTNGW 25 of the network 10 (step 1502). The PSTNGW 25 transmits the call setting request signal received from the exchange (not shown) to the SIP server 20 (step 1503). When the SIP server 20 receives the call setting request signal addressed to the terminal 42 from the PSTNGW 25, the SIP server 20 transmits a provisional response signal to the telephone 44, recognizes that the call setting request signal is not notified, and sets the terminal 42. Terminal registration information is checked in the storage unit 203. When recognizing that the calling telephone number is registered in the setting information of the terminal registration information, SID1 of the request identifier is read and a call setting request signal including SID1 is transmitted to the MS 30 (step 1504).

  When receiving the call setup request signal from the SIP server 20, the MS 30 transmits a response signal to the SIP server 20 (step 1505). Further, SID1 included in the call setting request signal is read, and a voice message corresponding to SID1 is read from the storage unit 303. When the SIP server 20 receives the response signal from the MS 30, the SIP server 20 transmits a response signal addressed to the telephone set 44 to the PSTNGW 25 (step 1506) and transmits an acknowledgment signal to the MS 30 (step 1507).

  The PSTNGW 25 transmits the response signal received from the SIP server 20 to the PSTN 60 (Step 1508). The exchange (not shown) in the PSTN 60 transmits the response signal received from the PSTNGW 25 to the telephone 44 (step 1509).

  When the telephone set 44 receives a response signal from an exchange (not shown) in the PSTN 60, the telephone set 44 transmits an acknowledgment signal to the MS 30 to establish a speech path between the telephone set 44 and the MS 30 (step 1510). When the communication path is established between these devices, the MS 30 transmits the voice message read from the storage unit 303 to the telephone 44 via the PSTNGW 25 and the PSTN 60 (step 1511). When the telephone 44 receives a voice message from the MS 30, a voice message “This is a number request service. Excuse me, please cancel the non-notification of the telephone number and call again.” Is output by voice.

  Here, the case where the network 10 is NGN will be described with reference to FIGS. 12 (a), 13 and 16. FIG. In FIG. 16, the SIP server 20 is the ISC 51 shown in FIG. 12A, and the SSC 53 is provided on the communication path between the ISC 51 and the terminal 42. In addition, it is assumed that the user of the terminal 42 is registered to receive the caller ID notification request service.

  When the user of the telephone 44 rejects the notification of the telephone number and calls the terminal 42, as shown in FIG. 13, "anonymous" is set in the display name of sip: in the P-Asserted-Identity header in INVITE. The telephone 44 transmits the INVITE to an exchange (not shown) in the PSTN 60. The INVITE addressed to the terminal 42 sent from the telephone 44 to the exchange (not shown) is sent to the ISC 51 via the PSTNGW 25. When the ISC 51 recognizes that “anonymous” is set in sip: in the P-Asserted-Identity header of the received INVITE, the ISC 51 transfers this INVITE to the MS 30.

  When ISC51 receives a voice message from MS30, “This is a number request service. Excuse me, but please dial 186 before the phone number and notify your phone number.” This voice message is transmitted to the PSTN 60 via the PSTNGW 25. An exchange (not shown) in the PSTN 60 transmits the received voice message to the telephone 44. Note that this voice message may be repeated twice or more.

  In the present embodiment, the case where the calling telephone number is registered in the setting information among the caller information has been described, but the same applies to the case of other information such as the name and location information of the caller. Detailed description is omitted. Further, the second or third embodiment may be applied to this embodiment.

  Furthermore, when the network 10 is NGN, the SIP server 20 has been described as the ISC 51 shown in FIG. 12A, but may be the SSC 56 or SSC 57 in FIG.

(Fifth embodiment)
In the present embodiment, the telephone set 44 is a public telephone set in the communication system shown in FIG.

  The configuration of the communication system according to this embodiment will be described. Here, differences from the fourth embodiment will be described, and a detailed description of the same configuration as that of the first embodiment or the fourth embodiment will be omitted.

  When transmitting the call setting request signal, the telephone 44 sets information indicating that the telephone is a public telephone in the call setting request signal and transmits the call setting request signal. When the SIP server 20 recognizes in the signal that the received call setting request signal is transmitted from the public telephone, the setting information is not registered in the terminal registration information of the destination terminal of the call setting request signal. As in the case, a call setting request signal is transmitted to the destination terminal.

  The operation of the communication system of this embodiment will be described. FIG. 18 is a sequence diagram showing an operation procedure of the communication system of the present embodiment.

  When the user of the telephone set 44 operates the telephone set 44 to input the telephone number of the terminal 42 and calls the terminal 42, the telephone set 44 transmits a call setting request signal including information indicating that the telephone set is a public telephone to the PSTN 60. (Step 1601).

  An exchange (not shown) in the PSTN 60 transmits a call setting request signal received from the telephone 44 to the PSTNGW 25 of the network 10 (step 1602). The PSTNGW 25 transmits the call setting request signal received from the exchange (not shown) to the SIP server 20 (step 1603). When the SIP server 20 receives a call setting request signal addressed to the terminal 42 from the PSTNGW 25, the SIP server 20 transmits a provisional response signal to the telephone 44. A signal is transmitted to the terminal 42 (step 1604).

  When the terminal 42 receives the call setting request signal from the SIP server 20, the terminal 42 transmits a provisional response signal to the SIP server 20, and when the user goes off-hook, transmits a response signal to the SIP server 20 (step 1605). When receiving the response signal from the terminal 42, the SIP server 20 transmits a response signal addressed to the telephone 44 to the PSTNGW 25 (step 1606) and transmits an acknowledgment signal to the terminal 42 (step 1607).

  The PSTNGW 25 transmits the response signal received from the SIP server 20 to the PSTN 60 (Step 1608). The exchange (not shown) in the PSTN 60 transmits the response signal received from the PSTNGW 25 to the telephone 44 (step 1609).

  When the telephone set 44 receives a response signal from an exchange (not shown) in the PSTN 60, the telephone set 44 transmits an acknowledgment signal to the terminal 42, and a speech path is established between the telephone set 44 and the terminal 42 (step 1610).

  Here, the case where the network 10 is NGN will be described with reference to FIGS. 12 (a), 13 and 16. FIG. In FIG. 16, the SIP server 20 is the ISC 51 shown in FIG. 12A, and the SSC 53 is provided on the communication path between the ISC 51 and the terminal 42. In addition, it is assumed that the user of the terminal 42 is registered to receive the caller ID notification request service.

  When the user of the telephone 44 calls the terminal 42, the telephone 44 is a public telephone. Therefore, as shown in FIG. 13, "Coin line /" is displayed in the display name of sip: in the P-Assigned-Identity header in INVITE. “payphone” is set, and the telephone 44 transmits the INVITE to an exchange (not shown) in the PSTN 60. The INVITE addressed to the terminal 42 sent from the telephone 44 to the exchange (not shown) is sent to the ISC 51 via the PSTNGW 25. When the ISC 51 recognizes that “Coin line / payphone” is set in sip: in the P-Assigned-Identity header of the received INVITE, the ISC 51 transmits this INVITE to the terminal 42. Thereafter, a communication path is established between the telephone 44 and the terminal 42 as described above.

  As shown in FIG. 13, when there is a conflict with other services such as “reject spam”, “Interaction with other service” is set in the Display Name of sip: in the P-Asserted-Identity header in INVITE. If notification is impossible due to other factors, “Unavailable” is set. In these cases, as in the case where the caller uses a public telephone, the ISC 51 transmits it to the destination terminal as a normal call setting request signal.

  Further, in the present embodiment, the case where the calling telephone number is registered in the setting information among the caller information has been described, but the same applies to the case of other information such as the name and location information of the caller. Detailed description is omitted. Further, the second or third embodiment may be applied to this embodiment.

  Furthermore, in the present embodiment, when the network 10 is NGN, the SIP server 20 has been described as the ISC 51 shown in FIG. 12A, but may be the SSC 56 or SSC 57 in FIG.

  In the first to fifth embodiments, the header setting method shown in FIG. 13 is not limited to NGN. Furthermore, in the first to fifth embodiments, if the terminal on the caller side includes the display unit 415 illustrated in FIG. 6, a guidance image may be displayed on the display unit 415. In the first embodiment, image message data is stored in the storage unit 303 of the MS 30 instead of the voice message sound source as a message for conveying the guidance to the caller. In the second embodiment, the storage unit of the SIP server 20 is stored. 203 and stored in 413 of the terminal 41 in the third embodiment. In addition, guidance by both voice and image messages may be notified to the caller.

  The image message may be an image in which guidance for requesting notification of information on the caller is displayed in text, or an image in which an error code for prompting the caller to notify information is displayed. Good. The error code may be different depending on the type of setting information.

  As described in the first to fifth embodiments, when the non-notification setting is made in the received call setting request signal, the session control server confirms the setting information of the destination terminal and sets the non-notification. If the set information is registered, a guidance to notify the information is output to the sender's terminal. This allows the caller to be notified of caller information such as the phone number of his / her terminal, and can confirm who the call is from.

  According to the present invention, in a communication method based on SIP, the caller is anxious about the incoming call from a nuisance call or silent call that makes the caller unclear about his / her information. Can reduce the annoying behavior.

  Further, as the caller information, not only the caller telephone number but also the caller's location information, the caller's name, or the caller's video can be notified.

  In addition, if the terminal of the user who has contracted the caller information request service can be specified by the contractor line, the start and stop of service provision can be easily set by contact from the user without performing the user authentication procedure.

  In addition, even if the user has multiple phone numbers other than the contract phone number, by adding all the phone numbers to one terminal registration information, the caller information request service is added in addition to the contract phone number. The telephone number can be uniformly reflected.

  Further, the call control means allows the media server to execute the guidance response call, so that the call control process can be performed during that time, and the call setting request signal including the non notification setting and the processing of other call setting request signals Can be performed simultaneously.

  Also, if the activation / deactivation of the setting information can be set by customer control from the user's telephone terminal, the user can easily change the setting information even after the contract.

  Furthermore, unlike the guidance such as "The phone number you have dialed is not currently used", the guidance for requesting caller information is answered by the device of the service provider on behalf of the contractor. If the guidance response call is charged to the caller, the effect of preventing annoying calls that make a call while hiding their information is improved.
