Problems solved by technology

The wireless transport mechanisms and frequencies employed by typical licensed wireless systems limit both data transfer rates and range.
As a result, the quality of service (voice quality and speed of data transfer) in licensed wireless systems is considerably inferior to the quality of service afforded by landline (wired) connections.
Thus, the user of a licensed wireless system pays relatively high fees for relatively low quality service.
The problem with landline connections is that they constrain the mobility of a user.

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 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.
