Generic access to the Iu interface
First Claim
1. A method of activating a packet transport channel (PTC) 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), wherein the GANC is communicatively coupled to the first communication system through a universal mobile telecommunication system (UMTS) terrestrial radio access network (UTRAN) Iu interface, the method comprising:
- receiving a radio access bearer (RAB) assignment request message at the GANC from the first licensed wireless communication system, wherein the RAB assignment request message comprises a radio access bearer identification (RAB-ID), a core network (CN) transport layer address, and a CN Iu transport association endpoint identifier;
sending a message requesting activation of the PTC from the GANC to a user equipment (UE), wherein the message comprises an endpoint identifier that the GANC assigns to the UE, a GANC IP address, and the RAB-ID;
receiving a message at the GANC from the UE, the message acknowledging activation of the PTC;
setting, at the GANC, a radio access network (RAN) IP address to an IP address of the UE;
setting, at the GANC, a RAN endpoint identifier to the endpoint identifier that the GANC assigns to the UE; and
sending a RAB assignment response message from the GANC to the first licensed wireless communication system, wherein the RAB assignment response message comprises the RAB-ID, the RAN endpoint identifier, and the RAN IP address.

Abstract
Some embodiments provide a method of activating a packet transport channel (PTC) in a communication system that includes a first licensed wireless communication system and a second generic access network (GAN) that has a generic access network controller (GANC). The GANC is communicatively coupled to the first communication system through a universal mobile telecommunication system (UMTS) terrestrial radio access network (UTRAN) Iu interface. The method sends a GA-PSR activate PTC request message from the GANC to a user equipment (UE). The message comprises a terminal endpoint identifier (TEID) that the GANC assigns to the UE. The message also receives a GA-PSR activate PTC acknowledge message from the UE at the GANC.
