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.

5. A communication system comprising:
-
a) a first communication system; and b) a second communication system comprising a network controller communicatively coupled to the first communication system through a universal mobile telecommunication system (UMTS) terrestrial radio access network (UTRAN) Iu interface, the network controller comprising a multi layer protocol architecture comprising a generic access radio resource control (GA-RRC) protocol layer; wherein the network controller uses the GA-RRC protocol layer to communicate both circuit switched signaling and packet switched signaling messages to a user equipment (UE). - View Dependent Claims (6, 7, 8, 9)
