Abstract

A system for handling a web service call by clients in a communication network is disclosed. The system comprises a client requester for issuing client requests. The client requests may comprise at least one client request to call a web service. The system also comprises a callback web Service that is coupled to the client requester for registering the at least one client request to call a web service and for invoking the called web service. A response web service is coupled to the callback web service for receiving a response to the at least one client request to call a web service and is also coupled to the client requester for delivering the response when a client request to obtain the response is issued from the client requester.

Claims

1. A system for handling a web service call by clients in a communication network comprising:

client requester means for issuing client requests comprising at least one client request to call a web service;

callback web service means coupled to the client requester means for registering the at least one client request to call a web service and for invoking the called web service; and

response web service means coupled to the callback web service means for receiving a response to the at least one client request to call a web service and coupled to the client requester means for delivering the response when a client request to obtain the response is issued from the client requester means.

2. The system of claim 1 wherein the callback web service means further comprise storage means to store a client identity along with a client request.

3. The system of claim 2 wherein the callback web service means further comprise means for determining whether the at least one client request to call a web service is already stored or not within the storage means.

4. The system of claim 1 wherein the client requests further comprise at least one client request to subscribe to an already stored at least one client request to call a web service.

5. The system of claim 1 wherein the at least one client request to call a web service comprises at least one parameter to define a protocol to be used for delivering the response to the client.

6. The system of claim 5 wherein the protocol is a Simple Mail Transfer Protocol (SMTP) or a Simple Object Access Protocol (SOAP).

7. A method for handling a web service call by a client in a communication network comprising the steps of:

issuing at least one client request to call a web service from a client requester;

registering the at least one client request to call a web service within a callback web service, and invoking the called web service;

receiving a response to the at least one client request to call a web service within a response web service; and

delivering the response when a client request to obtain the response is issued from the client requester.

8. The method of claim 7 further comprising after the registering step, the step of storing a client identity along with a client request.

9. The method of claim 8 further comprising after the issuing step, the step of determining whether the at least one client request to call a web service is already stored or not.

10. A computer program product stored on computer usable medium, comprising computer readable program means for causing a computer to perform a method according to claim 7.
