The state information is state identification information that can identify a communication state such as, for example, during a call, a successful call, a confirmation response of a successful call, and a call end. The cause change information of the state change is cause identification information indicating the cause of the change in the communication state such as, for example, when the user picks up the handset or when the user places the handset during the call.
As the transfer condition information stored in advance by the state transition detection unit 61, for example, when a SIP signal addressed to the SIP-URI “sip: 9999@xxx.co.jp” arrives, the SIP signal is transferred to the transfer device 9. To do. "

  The application server 7 includes a subscriber information management unit 70 and a state transition detection unit 71. The application server 7 acquires subscriber information from the communication terminal 3 and the dual-purpose terminal 5 connected to the communication network 1, and the acquired subscriber information Whether or not the state transition information is transmitted to the transfer device 9 by determining whether or not the change of the subscriber information corresponds to predetermined transfer condition information when it has changed from the previous acquisition of the subscriber information Determine. The application server 7 transmits state transition information to the transfer device 9 when the state change corresponds to the predetermined transfer condition information.

  In the application server 7, the subscriber information management unit 70 acquires subscriber information such as connection base station information indicating to which base station the terminal of the communication terminal 3 or the dual-purpose terminal 5 is connected, for example, It is stored in association with the identification information. In addition, when the subscriber information is acquired, if the previously acquired subscriber information is different from the acquired subscriber information, the subscriber information management unit 70 indicates that the subscriber information has changed and the two subscriptions before and after the change. The state transition detection unit 71 is notified of the person information.

When the change of the subscriber information is notified from the subscriber information management unit 70, the state transition detection unit 71 stores the subscriber information before the change stored in the subscriber information management unit 70 and the subscriber information after the change. Based on the above, the presence / absence of a state change is determined. For example, when the position information of the shared terminal 5 changes or when the subscriber's state changes, the state transition detection unit 71 determines whether or not the subscriber information state changes corresponding to predetermined transfer condition information stored in advance. If it is determined that it corresponds to the transfer condition information, the state information including the state information and the cause information of the state change is transmitted to the transfer device 9.
The transfer condition information stored in advance by the state transition detection unit 71 is, for example, “if the identifier of the base station to which the dual-purpose terminal 5 is connected changes, it is transferred to the transfer device 9”.

In the transfer device 9, the setting information receiving unit 15 receives the setting information transmitted from the setting terminal 16 and writes the received setting information in the setting information storage unit 12.

  The setting information storage unit 12 stores setting information including identification information for each subscriber received by the setting information receiving unit 15 and destination information for the subscriber. Here, the identification information for each subscriber is, for example, identification information for each subscriber such as a telephone number or SIP-URI. The destination information is an address of a transmission destination when information is transmitted to a device having the identification information. For example, a URL of a web server, a mail server, a file server, or the like that is the information network server 8 of the information network 2 (Uniform Resource Locators) and destination information such as a mail address.

The signal determination unit 11 receives state transition information from the call control device 6 or the application server 7. Further, the signal determination unit 11 determines which conversion method is used to convert the received state transition information based on the protocol of the received state transition information and the destination identification information indicating the destination in the state transition information. . In this conversion method determination, the signal determination unit 11 stores a predetermined conversion method determination condition in an internal storage area in advance, and whether or not a predetermined conversion method determination condition stored in the internal storage area is satisfied. Judgment by.
The signal determination unit 11 outputs the identification information and the state transition information of the information conversion units 131 to 135 corresponding to the determined conversion method of the state transition information to the signal conversion unit 13. Here, the identification information of the information conversion unit corresponding to the determined conversion method of the state transition information is identification information indicating which of the plurality of information conversion units for each conversion method the signal conversion unit 13 has.

The signal converter 13 includes a first format converter 131, a second format converter 132, a third format converter 133, a fourth format converter 134, and a fifth format converter 135 as information converters for each conversion method. The state transition information is converted according to the identification information of the information conversion unit input from the signal determination unit 11.
Specifically, for example, when the state transition information received by the transfer device 9 is an INVITE signal that is a SIP call connection signal, and the SIP signal is converted to HTTP, the signal conversion unit 13 sets the INVITE signal. The URL of the web server that is the information network server 8 is read out from the setting information storage unit 12 using the SIP-URI address indicating the destination as a search key. Then, the signal conversion unit 13 uses the source SIP-URI included in the INVITE signal and the medium information (such as audio / video) included in the SIP signal as HTTP request parameters, and the HTTP corresponding to the protocol of the information network server 8. Generate a request.

Further, the signal conversion unit 13 reads out information including destination information for transmitting the converted state transition information from the setting information storage unit 12 using the destination information included in the state transition information as a search key, and the information network of the information network 2 The converted state transition information is transmitted to the server 8. Further, the signal converter 13 returns the response information received from the information network server 8 to a signal suitable for the communication network 1. Specifically, for example, the signal conversion unit 13 converts the destination information of the SIP signal received from the call control device 6 or the application server 7 into the destination information included in the received response information based on the received response information. rewrite.
The signal transfer unit 14 transmits response information suitable for the communication network 1 to the communication network 1 by the signal conversion unit 13.

The signal determination unit 11 stores, in the internal storage area, for example, the correspondence relationship between the conversion method determination condition for the state transition information and the conversion method corresponding to the conversion method determination condition as follows. The signal determination unit 11 performs the state transition information conversion method determination based on this correspondence.
In the case where the state transition information is a number starting with “0120” and the “To header” of the SIP protocol INVITE signal, the signal determination unit 11 converts the state transition information from the SIP signal to the HTTP request. The conversion unit 131 is selected.
Similarly, when the state transition information is “SIP protocol INVITE signal” and “To header” is a number starting from “0660”, the signal determination unit 11 converts the SIP into an HTTP request. 132 is selected.
When the state transition information is “INVITE signal of SIP protocol”, the signal determination unit 11 selects the third format conversion unit 133 that converts the SIP into a SOAP request.
When the state transition information is “200 OK signal of SIP protocol”, the signal determination unit 11 selects the fourth format conversion unit 134 that converts the SIP into a SOAP request.
When the state transition information is “HTTP protocol” and “DATA parameter“ LOCATION ”is set”, the signal determination unit 11 selects the fifth format conversion unit 135 for converting the HTTP position information into the HTTP request. To do.

  Note that the state transition information conversion function provided in the signal conversion unit 13 in the present embodiment is not limited to the above, and a different conversion function for each combination of protocol, destination information, state information, and the like when the state transition information is received. Can be provided. For example, the state transition information conversion function of the signal conversion unit 13 includes HTTP conversion, SMTP conversion, FTP conversion, and the like.

In the information network 2, the information network server 8 includes an application that provides a service to the user by performing signal processing based on the request parameter of the received HTTP request. Further, when the information network server 8 transmits the response information for the HTTP request, that is, when the request signal for requesting the SIP-URI of the terminal responding to the call is received from the transfer device 9, the information network server 8 is arbitrarily set as the response information. The SIP-URI is returned.
Here, for example, when a business operator managing the information network server 8 has contracted a plurality of telephone lines for a call center, any one telephone number is returned as response information of an HTTP request. Arbitrary SIP-URI means that in such a case, it is a SIP-URI of one of a plurality of contracted telephone lines.

Next, an operation example of the service cooperation system in an embodiment of the present invention will be described with reference to FIG.
In the present embodiment, an operation example including the first process and the second process will be described by taking the following case as an example. In the first process, the setting terminal 16 operated by the information network administrator transmits the setting information input by the operation to the transfer device 9, and the setting information received by the setting information receiving unit 15 in the transfer device 9. Is written in the setting information storage unit 12.

  In the second process, the call control device 6 receives a call signal from the communication terminal 3, and the call control device 6 transmits state transition information corresponding to the received call signal to the transfer device 9. In the transfer device 9, the state transition information received from the call control device 6 is converted, and the converted state transition information is transmitted to the information network server 8. Here, it is assumed that the information network server 8 includes a web application that accepts an HTTP request. The information network server 8 transmits response information corresponding to the received state transition information after conversion to the transfer device 9, and the transfer device 9 converts the received response information according to the protocol of the call control device 6, The converted response information is transmitted to the call control device 6. Here, as an example of the cooperation service, a case where a web application that changes a telephone that responds with time is developed by an information network service developer and the web application is provided on the information network server 8 will be described as an example.

<First process>
In FIG. 3, the setting terminal 16 is operated by the information network manager and transmits the setting information input by the operation to the transfer device 9 (step S1). In the transfer device 9, the setting information receiving unit 15 receives the setting information (step S2), and stores the received setting information in the setting information storage unit 12 (step S3).
In addition, the setting terminal 16 receives input from the information network administrator, and responds to the information network server 8 as an application in the web service by responding with an XX number from 8:00 to 18:00, and responding with an XX number at other times. The application to be written is written (step S4).

<Second process>
The communication terminal 3 transmits a call signal indicating a call to the call control device 6 (step S5). In the call control device 6, the call control unit 60 receives the call signal and outputs the received call signal to the state transition detection unit 61 (step S6). The state transition detection unit 61 determines whether or not the input call signal is a state change corresponding to the transfer condition (step S7). At this time, when it is determined that the input call signal does not satisfy the transfer condition, the call control unit 60 performs signal processing according to the call signal and ends the process (step S20). On the other hand, when it is determined that the input call signal satisfies the transfer condition, the state transition detection unit 61 transmits the state transition information corresponding to the call signal to the transfer device 9 (step S8).

In the transfer device 9, the signal determination unit 11 receives the state transition information (step S9), and based on the received protocol of the state transition information, the state information, and the cause information of the state change, as described above, The conversion method is determined, and the identification information of the information conversion unit corresponding to the determined conversion method and the state transition information are output to the signal conversion unit 13 (step S10).
In the signal conversion unit 13, the information conversion unit corresponding to the input identification information of the information conversion unit, for example, the first format conversion unit 131 converts the input state transition information into the information network server 8 according to a predetermined conversion method. The state transition information is converted into an HTTP request format that can be accepted. Here, since the state transition information received from the call control device 6 is state transition information based on a call signal from the communication terminal 3, the HTTP request requests a SIP-URI that is a communication destination of the communication terminal 3. A request signal will be included.

The first format conversion unit 131 reads the destination address of the converted state transition information from the setting information storage unit 12 using the destination information of the input state transition information as a search key (step S11).
The first format conversion unit 131 transmits the converted state transition information to the information network server 8 of the information network 2 based on the read reply destination address (step S12).

  When the information network server 8 receives the converted state transition information from the transfer device 9, the information network server 8 generates response information in response to a request signal for requesting the SIP request URI of the HTTP request that is the converted state transition information. At this time, in step S4, the application written from the setting terminal 16 uses the information including the SIP-URI indicating the telephone number corresponding to the reception time of the HTTP request as response information, and transmits the generated response information to the transfer device 9. (Step S13).

  When the transfer device 9 receives the response information from the information network server 8 (step S14), as described above, the signal conversion unit 13 receives the destination information of the SIP signal received from the call control device 6 from the information network server 8. By rewriting the SIP-URI of the received response information, the response information is converted into response information suitable for the communication network 1 (step S15). The signal conversion unit 13 transmits the converted response information to the call control device 6 (step S16). In the call control device 6, the call control unit 60 receives the response information and performs connection processing (step S17).

As described above, according to the best mode for carrying out the present invention, it is possible for an information service developer of an information network to develop a cooperation service with a communication service in a general development method and development environment. effective. Further, according to the present invention, a change in the state of call control managed in the communication network or a change in subscriber information can be used in the information service of the information communication network, and a new information service using the information It is possible to obtain the advantage that development of the above can be easily performed.
Further, according to the present invention, development of a new link service that links an information service of an information network and a communication service of a communication network is promoted, and a new service is provided for both the communication network service provider and the information network service provider. The advantage of opening up the market is obtained.

  In the embodiment, the information network server 8 is configured to transmit the SIP-URI of one of a plurality of contracted telephone lines as response information to the transfer apparatus 9 as response information. For example, when it is determined that the customer is an important customer based on the SIP-URI of the subscriber who is the caller, that is, the information network server 8 stores the SIP-URI of the important customer in advance, and the information network server 8 performs step S12. If the SIP-URI of the transmission source of the request information received at the information network server 8 matches the SIP-URI of the important customer stored in the information network server 8, the SIP-URI that is easily connected as the SIP-URI to be transmitted as the destination information of the response information Or SIP-URI for important customers, etc., and SIP-URI for important customers It does not match the source of the SIP-URI of the determined information, if it is determined that the request information from the general customer, it may be a not change the SIP-URI. According to the present invention, when developing such an application that communicates with a communication network, even an engineer who does not have a skill to develop a communication service of the communication network can easily perform the process more than the conventional one provided in the information network server 8. It is possible to develop an application that provides an advanced transfer service.

Further, according to the present invention, when the application server 7 detects a change in the location information of the subscriber, the change in the location information of the user as the subscriber information is transmitted to the information network server 8 as an HTTP request. By providing the transfer device 9, it can be easily implemented, and a service developer in the information network can always provide a service that grasps the location of the subscriber. There is an effect that it is easy to realize a ubiquitous service characterized by dynamically changing service contents.
Further, according to the present invention, the state transition information can be applied to the state transition information of the service state of the service being provided to the user in the service provided by the application server 7 or the information network server 8.
