Abstract

The present invention provides a method, system, and RNC for implementing service functions in a shared radio access network (RAN). The method includes: dividing different subsystems of a physical radio network controller (RNC) into different logical RNCs and coupling each logical RNC to at least one service function entity, where the service function entity belongs to at least one operator and service function entities of different operators implement independent service functions through coupled logical RNCs. The present invention also provides a system and RNC for implementing service functions in a shared RAN. With the present invention, different operators in a shared RAN may use different service function entities to meet their own service function requirements.

Claims

1. A method for implementing service functions in a shared Radio Access Network (RAN) comprising:

dividing subsystems of a physical Radio Network Controller (RNC) into at least two logical RNCs; and

coupling the at least two logical RNCs to at least two service function entities, wherein any one of the service function entities implements independent service functions through the corresponding logical RNC.

2. The method according to claim 1,

wherein each of the subsystem includes a Central Processing Unit (CPU) and is configured as one of the logical RNCs.

3. The method according to claim 1, wherein coupling the at least two logical RNCs to the at least two service function entities comprises:

independently coupling each of the logical RNCs to one of the service function entities.

4. The method according to claim 1, wherein coupling the at least two logical RNCs to the at least two service function entities comprises:

independently coupling at least one of the logical RNCs to one of the service function entities and coupling at least two of the logical RNCs to a same service function entity.

5. The method according to claim 1, wherein at least one of the service function entities comprises:

a Cell Broadcast Centre (CBC) configured to implement functions of a Cell Broadcast Service.

6. The method according to claim 1, wherein at least one of the service function entities comprises:

a Stand Alone Serving Mobile Location Centre (SAS) configured to implement functions of a location service.

7. The method according to claim 1, wherein the method further comprises:

implementing different service functions by the at least two service function entities if the at least two service function entities are coupled to a same logical RNC.

8. The method according to claim 1, wherein the method further comprises:

implementing, by one service function entity of the at least two service function entities, independent service functions through one of the multiple logical RNCs if the multiple logical RNCs are coupled to a same function entity.

9. A Radio Network Controller (RNC) for implementing service functions in a shared Radio Access Network (RAN) comprising:

at least two logical RNCs divided according to subsystems of a physical RNC, wherein the at least two logical RNCs are coupled to at least two service function entities, and wherein any one of the service function entities implements independent service functions through the corresponding logical RNC.

10. The RNC of claim 9, wherein each of the logical RNCs is independently coupled to one of the service function entities.

11. The RNC of claim 9, wherein at least one of the logical RNCs is independently coupled to one of the service function entities and at least two of the logical RNCs are coupled to a same service function entity.

12. The RNC of claim 9, wherein one of the logical RNCs is corresponding to one of the subsystems of the physical RNC.

13. A system for implementing service functions in a shared Radio Access Network (RAN) comprising:

at least two logical RNCs divided according to subsystems of a physical RNC; and

at least two service function entities coupled to the at least two logical RNCs, wherein each of the service function entities belongs to at least one operator, and is configured to implement independent service functions through the corresponding logical RNC coupled to the service function entity.

14. The system of claim 13, wherein each of the logical RNCs is independently coupled to one of the service function entities.

15. The system of claim 13, wherein at least one of the logical RNCs is independently coupled to one of the service function entities and at least two of the logical RNCs are coupled to a same service function entity.

16. The system of claim 13, wherein one of the logical RNCs is corresponding to one of the subsystems of the physical RNC.

17. The system of claim 13, wherein at least one of the service function entities comprises:

a Cell Broadcast Centre (CBC) configured to implement functions of a Cell Broadcast Service.

18. The system of claim 13, wherein at least one of the service function entities comprises:

a Stand Alone Serving Mobile Location Centre (SAS) configured to implement functions of a location service.
