Abstract

Some embodiments are implemented in a communication system that includes a first communication system comprised of a licensed wireless radio access network and a core network, and a second communication system comprising a plurality of user hosted access points and a network controller. In some embodiments, each access point operates using short range licensed wireless frequencies to establish a service region. In some embodiments, the network controller communicatively couples the core network to the plurality of access points. Some embodiments provides a method of user equipment registration with a closed subscriber group (CSG) where a network controller receives a registration request for a UE from an access point including an initial non-access stratum (NAS) message from the user equipment and a CSG identifier (CSG-ID). The network controller forwards the NAS and CSG-ID the core network. The method receives, at the network controller, a permanent identifier from the core network and completing registration. The method uses the permanent identity of the UE to complete the ULE registration.

Claims

1. In a communication system comprising (i) a first network comprising a licensed wireless radio access network and a core network and (ii) a second network comprising a plurality of user hosted access points for establishing service regions of the second network using short range licensed wireless frequencies and a network controller for communicatively coupling user equipment operating in the service regions to the core network, a method for user equipment (UE) registration with a closed subscriber group (CSG) system comprising a particular group of UEs authorized to access the services of the access point, the method comprising:

receiving a UE registration request at the network controller from an access point, said request comprising an initial NAS message from said UE and a CSG identification associated with said access point;

relaying said registration request comprising said initial NAS message and said CSG identification to the core network;

receiving a permanent identity of the UE from the core network based on said registration request; and

using the permanent identity of the UE to complete said UE registration.

2. The method of claim 1, wherein said initial NAS message is one of a location area update (LAU) or a Paging Response and a CM Service Request message.

3. The method of claim 1, wherein said registration request comprises a location area code (LAC) and one of a temporary mobile subscriber identity (TMSI) of said UE and a packet-temporary mobile subscriber identity (P-TMSI) of said UE.

4. The method of claim 1, wherein said network controller is a home node B gateway (HNB-GW) and said access point is a home node B (HNB).

5. The method of claim 1, wherein said CSG identification is an identity of said access point.

6. The method of claim 1, wherein said CSG identification comprises identification of a plurality of access points the UE is authorized to access.

7. The method of claim 1, wherein said permanent identity comprises an international mobile subscriber identity (IMSI).

8. The method of claim 1, wherein said receiving the permanent identity of the UE comprises receiving an ID message comprising a modified RANAP message.

9. In a communication system comprising (i) a first network comprising a licensed wireless radio access network and a core network and (ii) a second network comprising a plurality of user hosted access points for establishing service regions of the second network using short range licensed wireless frequencies and a network controller for communicatively coupling user equipment operating in the service regions to the core network, a method for associating a temporary identity and a permanent identity of a user equipment (UE) at a network controller, the method comprising:

receiving a UE registration request at the network controller from an access point, said request comprising an initial NAS message from said UE and a CSG identification associated with said access point;

relaying said registration request comprising said initial NAS message and said CSG identification to the core network receiving an ID message comprising a permanent identity of the UE from the core network; and

associating said permanent identity with said UE at the network controller to provide services of the second network for the UE.

10. The method of claim 9, wherein said initial NAS message is one of a location area update (LAU) or a Paging Response and a CM Service Request message.

11. The method of claim 9, wherein said UE registration request comprises a location area code (LAC) and one of a temporary mobile subscriber identity (TMSI) of said UE and a packet-temporary mobile subscriber identity (P-TMSI) of said UE.

12. The method of claim 9, wherein said network controller is a home node B gateway (HNB-GW) and said access point is a home node B (HNB).

13. The method of claim 9, wherein said CSG identification is an identity of said access point.

14. The method of claim 9, wherein said CSG identification comprises identification of a plurality of access points the UE is authorized to access.

15. The method of claim 9, wherein said ID message is a COMMON ID message.

16. The method of claim 9, wherein said permanent identity comprises an international mobile subscriber identity (IMSI).

17. The method of claim 9, wherein said ID message is a modified RANAP message.

18. In a communication system comprising (i) a first network comprising a licensed wireless radio access network and a core network and (ii) a second network comprising a plurality of user hosted access points for establishing service regions of the second network using short range licensed wireless frequencies and a network controller for communicatively coupling user equipment operating in the service regions to the core network, a method for filtering pages at a network controller using a closed subscriber group (CSG) identity (CSG-ID), the CSG system comprising a particular group of UEs authorized to access the services of the access point the method comprising:

receiving a UE registration request at the network controller from an access point, said request comprising an initial NAS message from said UE and a CSG-ID associated with said access point;

relaying said registration request comprising said initial NAS message and said CSG-ID to the core network;

receiving an ID message comprising a permanent identity of the UE from the core network; and

filtering a set of page messages from the core network for the UE using said permanent identity and said CSG-ID.

19. The method of claim 18, wherein said UE registration request comprises a location area code (LAC) and one of a temporary mobile subscriber identity (TMSI) of said UE and a packet-temporary mobile subscriber identity (P-TMSI) of said UE.

20. The method of claim 18, wherein said network controller is a home node B gateway (HNB-GW) and said access point is a home node B (HNB).

21. The method of claim 18, wherein said CSG-ID is an identity of said access point.

22. The method of claim 18, wherein said CSG-ID comprises identification of a plurality of access points the UE is authorized to access.

23. The method of claim 18, wherein said permanent identity is an international mobile subscriber identity (IMSI).

24. The method of claim 18, wherein said ID message is a modified RANAP message.
