System and method for supporting GAN service request capability in a wireless user equipment (UE) device
In one embodiment, a scheme is disclosed for supporting wireless access network service request capability in a user equipment (UE) device that is operable in wide area cellular network (WACN) bands as well as in wireless access network bands (e.g., GAN bands and/or UMA bands). The UE device includes capability for gaining Internet Protocol (IP) connectivity with a wireless access network node (e.g., a GAN controller (GANC) or UMA network controller (UNC)). Thereafter, the UE device is operable to initiate a registration request message towards the wireless access network node, wherein the registration request message includes at least one information element pertaining to wireless access network services required by the UE device.
1. A messaging method, comprising:
gaining Internet Protocol (IP) connectivity by a user equipment (UE) device with respect to a network node disposed in a network environment that is comprised of a wireless access network (AN) space operable to be coupled to a wide area cellular network (WACN) space, wherein the WACN space includes one or more WACNs, wherein the network node is configured to provide access to the one or more WACNs for the UE device, wherein the network node comprises a default network controller whose information is stored in the UE device, wherein the network node comprises a generic access network controller (GANC), and wherein the GANC is a default GANC whose information is stored in the UE device;
sending a message by the UE device towards the network node, wherein the message comprises location information associated with the UE device and at least one information element pertaining to AN services required by the UE device, wherein the message is initiated towards the network node;
receiving, at the UE device from the network node, a response message comprising a list of available WACNs based on the location information associated with the UE device and the AN services required by the UE;
selecting, by the UE device, a WACN from the list of available WACNs; and
storing a Fully Qualified Domain Name (FQDN) in the UE device, the FQDN for facilitating a Domain Name Query (DNS) with respect to an IP address for the purposes of gaining IP connectivity by the UE to the WACN.
2. The messaging method of claim 1 , wherein the network node comprises an Unlicensed Mobile Access (UMA) network controller (UNC).
3. The messaging method of claim 2 , wherein the UNC is a default UNC whose information is stored in the UE device.
4. The messaging method of claim 1 , wherein the list of available WACNs is from the one or more WACNs of the WACN space coupled to the network node.
5. The messaging method of claim 1 , wherein the message is a registration request message.
6. The messaging method of claim 1 , wherein the default network controller is configured to provide interfacing functionality with respect to at least one of the WACNs.
7. The messaging method of claim 6 , wherein the interfacing functionality comprises protocol interworking.
8. A user equipment (UE) device, comprising:
a memory; and
at least one hardware processor communicatively coupled with the memory and configured to
gain Internet Protocol (IP) connectivity with respect to a network node disposed in a network environment that is comprised of a wireless access network (AN) space operable to be coupled to a wide area cellular network (WACN) space, wherein the WACN space includes one or more WACNs, wherein the network node is configured to provide access to the one or more WACNs for the UE device, wherein the network node comprises a default network controller whose information is stored in the UE device, wherein the network node comprises a generic access network controller (GANC), and wherein the GANC is a default GANC whose information is stored in the UE device;
send a message towards the network node, wherein the message comprises location information associated with the UE device and at least one information element pertaining to AN services required by the UE device, wherein the message is initiated towards the network node;
receive, from the network node, a response message comprising a list of available WACNs based on the location information associated with the UE device and the AN services required by the UE;
select a WACN from the list of available WACNs; and
store a Fully Qualified Domain Name (FQDN) in the UE device, the FQDN for facilitating a Domain Name Query (DNS) with respect to an IP address for the purposes of gaining IP connectivity by the UE to the WACN.
9. The UE device of claim 8 , wherein the network node comprises an Unlicensed Mobile Access (UMA) network controller (UNC).
10. The UE device of claim 9 , wherein the UNC is a default UNC whose information is stored in the UE device.
11. The UE device of claim 8 , further comprising a storage device that stores an IP address in the UE device, the IP address for identifying the network node.
12. The UE device of claim 8 , wherein the list of available WACNs is from the one or more WACNs of the WACN space coupled to the network node.
13. The UE device of claim 8 , wherein the message is a registration request message.
14. The UE device of claim 8 , wherein the default network controller is configured to provide interfacing functionality with respect to at least one of the WACNs, and wherein the interfacing functionality comprises protocol interworking.
15. A network system, comprising:
a network node disposed in a network environment that is comprised of a wireless access network (AN) space operable to be coupled to a wide area cellular network (WACN) space, wherein the WACN space includes one or more WACNs, wherein the network node is configured to provide access to the one or more WACNs for a user equipment (UE) device, and wherein the network node comprises a default network controller whose information is stored in the UE device, wherein the network node comprises a generic access network controller (GANC), and wherein the GANC is a default GANC whose information is stored in the UE device; and
the UE device, wherein the UE device is configured to:
gain Internet Protocol (IP) connectivity with the network node;
send a message towards the network node, wherein the message comprises location information associated with the UE device and at least one information element pertaining to AN services required by the UE device, wherein the message is initiated towards the network node;
receive, from the network node, a response message comprising a list of available WACNs based on the location information associated with the UE device and the AN services required by the UE;
select a WACN from the list of available WACNs; and
store a Fully Qualified Domain Name (FQDN) in the UE device, the FQDN for facilitating a Domain Name Query (DNS) with respect to an IP address for the purposes of gaining IP connectivity by the UE to the WACN.
16. The network system of claim 15 , wherein the network node comprises an Unlicensed Mobile Access (UMA) network controller (UNC).
17. The network system of claim 16 , wherein the UNC is a default UNC whose information is stored in the UE device.
18. The network system of claim 15 , wherein the list of available WACNs is from the one or more WACNs of the WACN space coupled to the network node.
