Abstract

A Third Generation Partnership Project (3GPP) media independent handover (MIH) service access point (SAP) is configured to provide MIH event services, (e.g., IEEE 802.21 event services), by mapping service primitives to the MIH event services. The service primitives may be 3GPP service primitives which originate from at least one of a radio resources (RR) layer, a logical link control (LLC) layer, a general packet radio service (GPRS) mobility management (GMM) layer, a session management (SM) layer, a non-access stratum (NAS), an access stratum (AS) and an evolved universal terrestrial radio access (E-UTRA)/evolved core network (E-CORE) system. The event services may include a link parameter change event service, a link up event service, a link going down event service, a link down event service, a handover complete event service and a link detected event service.

Claims

1. A method for mapping service primitives to event services, the method comprising:

receiving at least one service primitive;

sending a query to a database based on the received service primitive;

obtaining information from the database in response to the query; and

providing an event service that corresponds to the received service primitive based on the information obtained from the database.

2. The method of claim 1 wherein the event service is a link parameter change event service.

3. The method of claim 1 wherein the event service is a link up event service.

4. The method of claim 1 wherein the event service is a link down event service.

5. The method of claim 1 wherein the event service is a handover complete event service.

6. The method of claim 1 wherein the event service is a link going down event service.

7. The method of claim 1 wherein the event service is a link detected event service.

8. The method of claim 1 wherein the event service is provided in accordance with the IEEE 802.21 standard.

9. The method of claim 1 wherein the received service primitive is a third generation partnership project (3GPP) service primitive.

10. The method of claim 1 wherein the service primitive is received from a radio resources (RR) layer.

11. The method of claim 1 wherein the service primitive is received from a logical link control (LLC) layer.

12. The method of claim 1 wherein the service primitive is received from a general packet radio service (GPRS) mobility management (GMM) layer.

13. The method of claim 1 wherein the service primitive is received from a session management (SM) layer.

14. The method of claim 1 wherein the service primitive is received from a non-access stratum (NAS).

15. The method of claim 1 wherein the service primitive is received from an access stratum (AS).

16. The method of claim 1 wherein the service primitive is received from an evolved universal terrestrial radio access (E-UTRA)/evolved core network (E-CORE) system.

17. The method of claim 1 wherein the event service is a media independent handover (MIH) event service.

18. Apparatus for mapping service primitives to event services, the apparatus comprising:

a mapping database; and

a processor coupled to the database, the processor being configured to receive at least one service primitive, send a query to the mapping database based on the received service primitive, obtain information from the mapping database in response to the query, and output an event service that corresponds to the received service primitive based on the information obtained from the mapping database.

19. The apparatus of claim 18 wherein the apparatus is a service access point (SAP).

20. The apparatus of claim 18 wherein the event service is a link parameter change event service.

21. The apparatus of claim 18 wherein the event service is a link up event service.

22. The apparatus of claim 18 wherein the event service is a link down event service.

23. The apparatus of claim 18 wherein the event service is a handover complete event service.

24. The apparatus of claim 18 wherein the event service is a link going down event service.

25. The apparatus of claim 18 wherein the event service is a link detected event service.

26. The apparatus of claim 18 wherein the event service is provided in accordance with the IEEE 802.21 standard.

27. The apparatus of claim 18 wherein the received service primitive is a third generation partnership project (3GPP) service primitive.

28. The apparatus of claim 18 wherein the service primitive is received from a radio resources (RR) layer.

29. The apparatus of claim 18 wherein the service primitive is received from a logical link control (LLC) layer.

30. The apparatus of claim 18 wherein the service primitive is received from a general packet radio service (GPRS) mobility management (GMM) layer.

31. The apparatus of claim 18 wherein the service primitive is received from a session management (SM) layer.

32. The apparatus of claim 18 wherein the service primitive is received from a non-access stratum (NAS).

33. The apparatus of claim 18 wherein the service primitive is received from an access stratum (AS).

34. The apparatus of claim 18 wherein the service primitive is received from an evolved universal terrestrial radio access (E-UTRA)/evolved core network (E-CORE) system.

35. The apparatus of claim 18 wherein the event service is a media independent handover (MIH) event service.
