Abstract

The present invention relates to a method and system for providing a service in a communication network. A service script is used to control a service execution functional unit to execute the service, wherein an execution priority is allocated to the service script based on the kind of service. Furthermore, a service logic of the service may be provided at a service execution functional unit, and the service script may comprise a service description of the service. The service execution functional unit is then controlled based on the service description to execute the service by using the service logic. Thus, the service script does not contain the service logic, and a flexible service script concept can be provided. Moreover, the signaling traffic can be reduced since the operator does not have to update service scripts for a large amount of subscribers.

Claims

1. A method for providing a service in a communication network (13), said method comprising the steps of:

a) generating a service script comprising a service description of said service;

b) providing a service logic of said service at a service execution functional unit (7-1, 7-2); and

c) controlling said service execution functional unit (7-1, 7-2) based on said service description to execute said service by using said service logic.

2. A method according to claim 1, further comprising the step of storing said service script at a service execution management functional unit (8), routing a call from a call control functional unit (9) to said execution management functional unit (8), and invoking said service by said service execution management functional unit (8) based on said service description.

3. A method according to claim 2, further comprising the step of providing said service execution functional unit (7-1, 7-2) and said service execution management functional unit (8) as separate entities at another service architecture layer than said call control functional unit (9).

4. A method according to claim 2, wherein said invoking step comprises invoking at least two service execution functional units (7-1, 7-2) in a serial or parallel manner to integrate services to obtain said service.

5. A method according to claim 1, further comprising the step of storing said service script at a script database (5) which is arranged at a location separated from said service execution functional unit (7-1, 7-2).

6. A method according to claim 1, further comprising the step of providing a user interaction functional unit (2) for enabling a user to create or configure said service script.

7. A method according to claim 6, further comprising the step of generating said service script at a service management server (3) based on information received from said user interaction functional unit (2).

8. A method according to claim 1, wherein said service script comprises a service triggering information defining trigger conditions for said controlling step.

9. A method according to claim 8, wherein said service description and service triggering information is coded in an XML-like language.

10. A method according to claim 1, wherein said service description comprises at least one of a service identification, an IP address of an external execution environment of said service execution functional unit (7-1, 7-2), an IP address of an external repository server (4), and a module information.

11. A method according to any one of the preceding claims, wherein said service script is divided into a plurality of script areas including service packages.

12. A method according to claim 11, wherein said script areas comprise user script areas for user defined services and service provider script areas for service provider services.

13. A method according to claim 12, wherein a priority is given to said user defined services over said service provider services.

14. A method according to claim 12, wherein a priority is allocated to said service scripts based on their type.

16. A method according to claim 15, wherein said kind of service comprises a universal service assigned to all subscribers of a service provider network, a subscription group service assigned to all subscribers within a certain user group, a user service assigned to one or several subscribers by a user, and an operator service assigned to one or several subscribers by a network operator.

17. A method according to claim 16, further comprising the step of storing a service script defining a subscription group service in a database (5) together with a group identification and a priority information defining the execution priority of the subscription group.

18. A method according to claim 16, further comprising the step of allocating a higher priority to a service script of a universal service and a lower priority to a service script of a user service.

19. A method according to claim 15, further comprising the step of loading a service script based on said execution priority, when a predetermined trigger condition is met, checking whether said trigger condition is defined in said loaded service script, and loading a new service script with a lower priority if the trigger condition has not been defined.

20. A method according to claim 15, further comprising the step of setting a flag in said service script to indicate an overriding status for a particular trigger, said overriding status defining whether service scripts with lower priorities are to be executed or not.

25. A system according to claim 1, wherein said system is arranged as a service network (11) separated from said communication network (13).

15. A method for providing a service in a communication network, said method comprising the steps of:

a) generating a service script defining said service;

b) controlling a service execution functional unit (7-1, 7-2) based on said service script to execute said service, and

c) allocating an execution priority for said service script based on the kind of service.

21. A system for providing a service in a communication network (13), said system comprising:

a) generating means (3) for generating a service script comprising a service description of said service;

b) service execution means (7-1, 7-2) comprising a service logic for executing said service; and

c) service execution management means (8) for controlling said service execution means (7-1, 7-2) based on said service description to execute said service by using said service logic.

22. A system according to claim 21, further comprising call control means (9) for routing a call to said service execution management means (8), wherein said service execution management means (8) is arranged to invoke said service at said service execution means (7-1, 7-2) based on said service description.

23. A system according to claim 21, wherein said service execution means (7-1, 7-2) and said service execution management means (8) are arranged as separate entities at another service architecture layer than said call control means (9).

24. A system according to claim 21, further comprising a service script database (5) for storing said service script, said service script database (5) being arranged as a central database separated from said service execution means (7-1, 7-2).

26. A system according to claim 21, wherein said service execution management means (8) is arranged to control said service execution means (7-1, 7-2) based on a priority allocated to said service script.

27. A system for providing a service in a communication network (13), said system comprising:

a) generating means (3) for generating a service script comprising a service description of said service;

b) service execution management means (8) for controlling service execution means (7-1, 7-2) based on said service description to execute said service; and

priority allocating means (82) for allocating an execution priority to said service script based on the kind of said service.
