Abstract

Some embodiments provide a method of registering a user equipment (UE) in a communication system that includes a licensed wireless communication system and a generic access network (GAN) that has a generic access network controller (GANC). The method sends a register request message from the UE to the GANC that indicates a GAN mode capability of A/Gb only for the UE. When the GANC has a GAN mode capability of A/Gb, the GANC registers the UE with the GAN. When the GANC has a GAN mode capability of Iu only, the GANC rejects the register request message. When the GANC has a GAN mode capability of both A/Gb and Iu, the GANC registers the UE based on a set of GANC mode selection rules that the GANC applies for registering UEs with the GAN.

Claims

1. A method of registering a user equipment (UE) in a communication system comprising a first licensed wireless communication system and a second generic access network (GAN) comprising a generic access network controller (GANC), the method comprising:

a) sending a register request message from the UE to the GANC indicating a GAN mode capability of A/Gb only for the UE;

b) when the GANC has a GAN mode capability of A/Gb, the GANC registering the UE with the GAN;

c) when the GANC has a GAN mode capability of Iu only, the GANC rejecting said register request message; and

d) when the GANC has a GAN mode capability of both A/Gb and Iu, the

GANC registering the UE based on a set of GANC mode selection rules for registering UEs with the GAN.

2. The method of claim 1, wherein said set of GANC mode selection rules utilizes information received by the GANC in the GAN register request message from the UE.

3. The method of claim 1, wherein said set of GANC mode selection rules utilizes information stored in the GANC.

4. The method of claim 1, wherein said set of GANC mode selection rules comprises service provider policies.
