Method and device for operating a group service in a communications network

1. A method of operating a group service or a plurality of group services in a communication network, comprising:

capturing group-service-specific and/or group-specific event data in an event detection unit;

transmitting at least one subset of the group-service-specific and/or group-specific event data from the event detection unit to a group list generation unit that is applicable to a plurality of types of communication group services; and

evaluating the group-service-specific and/or group-specific event data and generating group-specific lists by the group list generation unit, the group-specific lists indicating a current participation state of members of the group in the group service or each of the communication group services,

wherein current participation state data is obtained, for the plurality of types of communication group services at a centralized location, after a change in a participation state occurs from a type of communication group service to a different type of communication group service, and information regarding which members are currently involved in which of the types of communication group services is made available to different applications and users in a standard manner.

2. The method as claimed in claim 1 , further comprising storing the group-specific lists in the group list generation unit.

3. The method as claimed in claim 1 , wherein

the group-service-specific and/or group-specific event data are logged by the event detection unit.

4. The method as claimed in claim 1 , wherein at least the subset of the group-service-specific and/or group-specific event data is transmitted from the event detection unit to the group list generation unit in each case directly after being captured.

5. The method as claimed in claim 1 , wherein

the group list generation unit evaluates the group-service-specific and/or group-specific event data and generates the group-specific lists in each case directly after at least the subset of the group-service-specific and/or group-specific event data has been received.

6. The method as claimed in claim 1 wherein

the group list generation unit receives a request for information regarding members who are active in at least one of the group services, and

the group list generation unit evaluates the group-service-specific and/or group-specific event data and generates the group-specific lists only after the group list generation unit receives the request for information.

7. The method as claimed in claim 1 , wherein

charging-related group-service-specific and/or charging-related group-specific event data is transmitted from the event detection unit to a group charge processing unit, and

the group charge processing unit evaluates the charging-related group-service-specific and/or the charging-related group-specific event data and generates use-dependent and participant-specific charging data.

8. The method as claimed in claim 7 , wherein

the charging-related group-service-specific and/or at least the charging-related group-specific event data are transmitted from the event detection unit to the group charge processing unit in each case directly after they have been captured.

9. The method as claimed in claim 7 , wherein

the charging data are transmitted from the group charge processing unit to at least one charging unit for participant-specific post-processing.

10. The method as claimed in claim 1 , wherein

the event detection unit is a group management server on which data relevant to setting up and managing the group services are stored.

11. The method as claimed in claim 1 , wherein

the event detection unit is a group service server which provides the group service to the group using the communication network.

12. The method as claimed in claim 1 , wherein

the communication network used is a mobile radio network.

13. The method as claimed in claim 1 , wherein

the group service is operated across a boundary of the communication network.

14. A system to operate a group service or a plurality of group services in a communication network, comprising:

an event detection unit to capture group-service-specific and/or group-specific event data; and

a group list generation unit, connected with the event detection unit, comprising:

a reception unit to receive at least one subset of the group-service-specific and/or group-specific event data from the event detection unit;

an analysis unit to evaluate the group-service-specific and/or group-specific event data for a plurality of types of communication group services; and

a multi-group service unit to generate group-specific lists indicating a current participation state of members of the group in the group service or each of the communication group services,

wherein current participation state data is obtained, for the plurality of types of communication group services at a centralized location, after a change in a participation state occurs from a type of communication group service to a different type of communication group service, and information regarding which members are currently involved in which of the types of communication group services is made available to different applications and users in a standard manner by the group list generation unit.

15. The system as claimed in claim 14 , further comprising:

a memory associated with the group list generation unit to store the group-specific lists.

16. The system as claimed in claim 14 , wherein

the event detection unit transmits at least the subset of the group-service-specific and/or group-specific event data to the group list generation unit in each case directly after it has been captured.

17. The system as claimed in claim 14 , wherein

the analysis unit evaluates the group-service-specific and/or group-specific event data and the multi-group service unit generates the group-specific lists in each case directly after at least the subset of the group-service-specific and/or group-specific event data has been received.

18. The system as claimed in claim 14 , wherein

the group list generation unit receives a request for information regarding members who are active in at least one of the group services, and

the analysis unit evaluates the group-service-specific and/or group-specific event data and the multi-group service unit generates the group-specific lists after the request for information has been received.

19. The system as claimed in claim 14 , wherein

the event detection unit is captures and transmits at least charging-related group-service-specific and/or at least charging-related group-specific event data to a group charge processing unit, and

the group charge processing unit evaluates the charging-related group-service-specific and/or at least the charging-related group-specific event data and generates use-dependent and participant-specific charging data.

20. The system as claimed in claim 19 , wherein

the event detection unit transmits the charging-related group-service-specific and/or at least the charging-related group-specific event data to the group charge processing unit directly after being captured.

21. The system as claimed in claim 19 , wherein

the group charge processing unit has a charging unit connected with it to receive the charging data and post-processing the charging data a participant-specific basis.

22. The system as claimed in claim 14 , wherein

the event detection unit is a group management server on which data for setting up and managing the group services are stored.
