Abstract

A communication entrepreneur has an application server 2 having message conversion function. The application server 2 performs service function distribution processing with reference to trigger rule 220 and message rule 230. The communication entrepreneur can provide various service functions without notifying individual server addresses to a service entrepreneur.

Claims

1. A communication system comprising:

an application server;

a Web server coupled to the application server; and

a plurality of service control servers coupled to the application server;

the Web server receives a request from a terminal for requesting one of the communication services included in a plurality of service functions embodied by the plurality of service control servers; and

transmits a first message to the application server based on the request, the first message being in conformity with Parlay X API and including an identifier of a first procedure;

the application server receives the first message from the Web server;

extracts the identifier of the first procedure from the received first message;

manages a relation between the identifier of the first procedure, a rule, and an IP address of a first service control server of the plurality of service control servers, based upon a rule information;

specifies the IP address of the first service control server and the rule, which correspond to the extracted identifier by using the rule information;

stores the received first message with a corresponding second message of a second procedure, based upon a message rule information provided for the rule;

converts the received first message into the corresponding second message based on the message rule information; and

sends the corresponding second message to the first service control server including the specified IP address;

the first service control server receives the corresponding second message from the application server; and

provides the requested service function based on the corresponding second message.

2. A communication system according to claim 1, wherein when the application server receives the first message in conformity with Parlay X API, Namespace information is extracted included from the first message and a corresponding service control server is specified from the Namespace information.

3. A communication system according to claim 1, the application server further detecting whether setting of additional information processing corresponding to the first message is present or not and performing the additional information processing when the additional information processing is set.

4. A communication system according to claim 1, the first message being in conformity with a web service API.

5. An application server coupled to a Web server and a plurality of service control servers, the application server being operatively configured to

receive a first message from the Web server, the first message being in conformity with Parlay X API and including an identifier of a first procedure;

extract the identifier of the first procedure from the received first message;

manage a relation between the identifier of the first procedure, a rule, and an IP address of a first service control server of the plurality of service control servers, based upon a rule information;

specify the IP address of the first service control server and the rule, which correspond to the extracted identifier by using the rule information;

store the received first message with a corresponding second message of a second procedure, based upon a message rule information provided for the rule;

convert the received first message into the corresponding second message based on the message rule information; and

send the corresponding second message to the service control server including the specified IP address.

6. An application server according to claim 5, wherein when the message in conformity with Parlay X API is received, Namespace information included in the first message is extracted and a corresponding service control server having service function is specified in accordance with the Namespace information.

7. An application server according to claim 5, the application server being operatively configured to convert the first message into a session control signal.

8. An application server according to claim 7, the session control signal being SIP.

9. An application server according to claim 5, the application server being operatively configured to detect whether additional information processing corresponding the first message is present or not and to perform a program corresponding to the additional information processing when the additional information processing is detected.

10. A communication method in a communication system including an application server, a Web server coupled to the application server, and a plurality of service control servers coupled to the application server, the method comprising:

receiving, by the Web server, a request from a terminal for requesting one of the communication services included in a plurality of service functions provided by the plurality of service control servers;

transmitting, by the Web server, a first message to the application server based on the request, the first message being in conformity with Parlay X API and including an identifier of a first procedure;

receiving, by the application server, the first message from the Web server;

extracting, by the application server, the identifier of the first procedure from the received first message;

managing, by the application server, a relation between the identifier of the first procedure, a rule, and an IP address of a first service control server of the plurality of service control servers, based upon a rule information;

specifying, by the application server, the IP address of the first service control server and the rule, which correspond to the extracted identifier by using the rule information;

storing, by the application server, the received first message with a corresponding second message of a second procedure, based upon a message rule information provided for the rule;

converting, by the application server, the received first message into the corresponding second message based on the message rule information;

sending, by the application server, the corresponding second message to the first service control server including the specified IP address;

receiving, by the first service control server, the corresponding second message from the application server; and

providing, by the first service control server, the requested service function based on the corresponding second message.

11. A communication method according to claim 10, the application server converting the first message into session control signal.
