Abstract

The invention relates to a service control device and method for controlling service execution in a communication network. A service script for a user is loaded in response to the receipt of an incoming message, and it is checked based on a comparison of the loaded service script and the incoming message whether a service is to be triggered. If a service triggering has been determined, a service is activated in an external service execution environment. Due to the fact that the service execution is not performed in the service control point but in an external service execution environment, the service logic does not have to be provided at the service control point. It provides a flexible way to define, execute, and control user-specific, operator, and third party services combining various service capabilities.

Claims

1. A method with respect to a control point of a communication network for activating and controlling a service execution, said method comprising:

loading a service script for a user in response to the receipt of an incoming message, wherein the service script includes a service description and triggering information, and wherein the service description provides information about an external service execution environment and a service logic repository server;

determining if a service is to be triggered based on a comparison of said incoming message with said triggering information;

sending a request for service invocation if the result of said determining is positive; and

activating and controlling the service in the external service execution environment indicated in the service description using a service logic provided by the service logic repository server.

2. The method according to claim 1, wherein said activating step comprises a message processing step if an existing message is to be modified or if a new message is to be created.

3. The method according to claim 1, further comprising the step of temporarily storing service scripts for active users in said control point.

4. The method according to claim 1, wherein said service description comprises an IP address of said external service execution environment and/or an IP address of said service logic repository server.

5. The method according to claim 1, further comprising the step of invoking and coordinating service execution in at least two external execution points.

6. The method according to claim 5, further comprising the step of coding a service interaction information in said service script.

7. The method according to claim 1, further comprising the step of performing a firewall function towards service execution in other service execution environments.

8. The method according to claim 1, further comprising the step of terminating an active service in response to the receipt of a corresponding request from said communication network.

9. The method according to claim 1, further comprising the step of handling both mobile-originated and mobile-terminated calls for said user in said control point.

10. A device for controlling service execution with respect to a control point in a communication network, said device comprising:

means for loading a service script for a user in response to the receipt of an incoming message, wherein the service script includes a service description and triggering information, and wherein the service description provides information about an external service execution environment and a service logic repository server;

means for determining if a service is to be triggered based on a comparison of said incoming message and said triggering information;

means for sending a request for service invocation if the result of said determining is positive; and

means for activating and controlling the service in the external service execution environment indicated in the service description using a service logic provided by the service logic repository server.

11. The device according to claim 10, further comprising protocol engine means for receiving and transmitting protocol messages and for passing incoming messages to said means for loading a service script.

12. The device according to claim 11, wherein said protocol engine means is an SIP engine.

13. The device according to claim 10, wherein said means for activating and controlling is arranged to contact a message processing means if a message processing is required.

14. The device according to claim 13, wherein said message processing means is an SIP message processor.

15. The device according to claim 13, wherein said message processing means is arranged to modify an existing message or to create a new message in response to a corresponding request from said means for activating and controlling.

16. The device according to claim 10, further comprising temporary storing means for storing service script of active users.

17. The device according to claim 10, wherein said means for activating and controlling is arranged to invoke and coordinate service execution in at least two external execution points.
