Abstract

Some embodiments provide a communication system that includes a first licensed wireless communication system, a second generic access network (GAN) that includes 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 communication system also includes a user equipment (UE). The GANC includes a UDP protocol layer and a GTP-U protocol layer over the UDP protocol layer of the GANC. The UE includes a UDP protocol layer and a GTP-U protocol layer over said UDP protocol layer of the UE. The UDP protocol layer of the GANC is communicatively coupled to the UDP protocol layer of the UE. The GTP-U protocol layer of the GANC is communicatively coupled to the GTP-U protocol layer of the UE.

Claims

1. A communication system comprising:

a) a first licensed wireless communication system;

b) 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; and

a user equipment (UE);

wherein the GANC comprises;

i) a UDP protocol layer; and

ii) a GTP-U protocol layer over said UDP protocol layer of the GANC;

wherein the UE comprises;

i) a UDP protocol layer; and

ii) a GTP-U protocol layer over said UDP protocol layer of the UE;

wherein the UDP protocol layer of the GANC is communicatively coupled to the UDP protocol layer of the UE;

wherein the GTP-U protocol layer of the GANC is communicatively coupled to the GTP-U protocol layer of the UE.
