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.

Claims

exact text as granted — not AI-modified
1 - 4 . (canceled) 
   
   
       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).   
   
   
       6 . The communication system of  claim 5 , wherein the first communication system comprises a mobile switching center (MSC), wherein the network controller inter-works the GA-RRC protocol to a RANAP protocol over an interface between the network controller and the MSC. 
   
   
       7 . The communication system of  claim 6 , wherein the interface between the network controller and the MSC is a 3GPP Iu-cs interface. 
   
   
       8 . The communication system of  claim 5 , wherein the first communication system comprises a serving general packet radio service (GPRS) support node (SGSN), wherein the network controller inter-works the GA-RRC protocol to a RANAP protocol over an interface between the network controller and the SGSN. 
   
   
       9 . The communication system of  claim 8 , wherein the interface between the network controller and the SGSN is a 3GPP Iu-ps interface. 
   
   
       10 . A network controller comprising:
 a) a generic access radio resource control (GA-RRC) protocol layer for communicatively coupling the GA-RRC protocol layer of the network controller to a GA-RRC protocol layer of a user equipment (UE); and   b) a set of access layers below the GA-RRC layer of the network controller for communicatively coupling the network controller to a set of access layers of the UE through a set of access layers of a generic IP network;   wherein the network controller is for communicatively coupling a first communication system comprising said network controller to a second communication system through a universal mobile telecommunication system (UMTS) terrestrial radio access network (UTRAN) Iu interface.   
   
   
       11 . The network controller of  claim 10  further comprising a remote IP layer below said GA-RRC layer of the network controller for communicatively coupling the network controller to a remote IP layer of the UE. 
   
   
       12 . The network controller of  claim 10  further comprising an IPSec layer below said remote IP layer of the network controller for communicatively coupling the network controller to an IPSec layer of the UE. 
   
   
       13 . The network controller of  claim 10  further comprising a transport IP protocol layer below the IPSec layer of the network controller and above the access layer of the network controller, the transport IP protocol layer of the network controller for communicatively coupling the network controller to a transport IP layer of the UE through a transport IP protocol layer of a generic IP network. 
   
   
       14 . The network controller of  claim 10 , wherein the second communication system comprises a mobile switching center (MSC), wherein the network controller inter-works the GA-RRC protocol to a RANAP protocol over an interface between the network controller and the MSC. 
   
   
       15 . The network controller of  claim 14 , wherein the interface between the network controller and the MSC is a 3GPP Iu-cs interface. 
   
   
       16 . The network controller of  claim 10 , wherein the second communication system comprises a serving general packet radio service (GPRS) support node (SGSN), wherein the network controller inter-works the GA-RRC protocol to a RANAP protocol over an interface between the network controller and the SGSN. 
   
   
       17 . The network controller of  claim 16 , wherein the interface between the network controller and the SGSN is a 3GPP Iu-ps interface.
