Patent ID: 7912004

Claim:
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.
