First Claim
Patent Images
1. A method performed by a user equipment (UE) device for selecting a generic access network (GAN) controller (GANC), said UE device being registered on a given Public Land Mobile Network (PLMN), the method comprising:
- if a list of PLMNs available via an access network has been obtained via one of Extensible Authentication Protocol (EAP) authentication and scanning and said given PLMN is in said list, constructing a Fully Qualified Domain Name (FQDN) comprising a PLMN ID of said given PLMN to obtain an Internet Protocol (IP) address of a selected GANC node, transmitting said FQDN via said access network, receiving an IP address corresponding to a-GANC node operably coupled to said given PLMN and authenticating with said GANC node for obtaining service via said GAN to said given PLMN; and
if a list of PLMNs has not been obtained, constructing one of a generic FQDN and a home FQDN, receiving at least one IP address for a corresponding GANC node operably coupled to a respective PLMN, selecting a GANC node operably coupled to one of said given PLMN and a home PLMN of said UE device if available, and authenticating with said selected GANC node for obtaining service via said GAN to a selected PLMN operably coupled thereto.

Abstract
In one embodiment, a scheme is provided for selecting a generic access network (GAN) controller by a user equipment (UE) device disposed in a network environment including a GAN. Responsive to a query request by the UE device, one or more IP addresses of GANC nodes are obtained, each node for accessing a particular Public Land Mobile Network (PLMN). The UE device then authenticates with at least one GANC node for obtaining access service to a PLMN coupled thereto.

7. A user equipment (UE) device operable for selecting a generic access network (GAN) controller (GANC), said UE device being registered on a given Public Land Mobile Network (PLMN), the UE device comprising:
-
a logic module operable, if a list of PLMNs available via an access network has been obtained via one of Extensible Authentication Protocol (EAP) authentication and scanning and the given PLMN is in the list, to construct a Fully Qualified Domain Name (FQDN) comprising a PLMN ID of the given PLMN to obtain an Internet Protocol (IP) address of a selected GANC node, to transmit said FQDN via said access network, to receive an IP address corresponding to said selected GANC node operably coupled to said given PLMN and to authenticate with said selected GANC node for obtaining service via said GAN to said given PLMN; and a logic module operable, if a list of PLMNs has not been obtained, to construct one of a generic FQDN and a home FQDN, receive at least one IP address for a corresponding GANC node operably coupled to a respective PLMN, to select a GANC node operably coupled to one of said given PLMN and a home PLMN of the UE device if available, and to authenticate with said selected GANC node for obtaining service via said GAN to a selected PLMN operably coupled thereto. - View Dependent Claims (8, 9, 10)
