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 network messaging method, comprising:
gaining Internet Protocol (IP) connectivity by a user equipment (UE) device with respect to a wireless access 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;
sending a message by said UE device towards said wireless access network node, wherein said message includes location information associated with said UE device and at least one information element pertaining to AN services required by said UE device, wherein said message is initiated towards said wireless access network node after a successful discovery procedure or a failed registration with a serving access network node;
receiving, at said UE device from said wireless access network node, a response message comprising a list of available WACNs based on the location information associated with said UE device and the AN services required by said UE;
selecting, by said UE device, a WACN from the list of available WACNs; and
storing a Fully Qualified Domain Name (FQDN) in said UE device, said FQDN for facilitating a Domain Name Query (DNS) with respect to an IP address of said wireless access network node.
2. The network messaging method as recited in claim 1 , wherein said wireless access network node comprises a generic access network controller (GANC).
3. The network messaging method as recited in claim 2 , wherein said GANC is a default GANC whose information is stored in said UE device.
4. The network messaging method as recited in claim 1 , wherein said wireless access network node comprises an Unlicensed Mobile Access (UMA) network controller (UNC).
5. The network messaging method as recited in claim 4 , wherein said UNC is a default UNC whose information is stored in said UE device.
6. The network messaging method as recited in claim 1 , wherein the list of available WACNs is from the one or more WACNs of the WACN space coupled to said wireless access network node.
7. The network messaging method as recited in claim 1 , wherein the message is a registration request message.
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 wireless access 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;
send a message towards said wireless access network node, wherein said message includes location information associated with said UE device and at least one information element pertaining to AN services required by said UE device, wherein said message is initiated towards said wireless access network node after a successful discovery procedure or a failed registration with a serving access network node;
receive, at said UE device from said wireless access network node, a response message comprising a list of available WACNs based on the location information associated with said UE device and the AN services required by said UE;
select, by said UE device, a WACN from the list of available WACNs; and
store a Fully Qualified Domain Name (FQDN) in said UE device, said FQDN for facilitating a Domain Name Query (DNS) with respect to an IP address of said wireless access network node.
9. The UE device as recited in claim 8 , wherein said wireless access network node comprises a generic access network controller (GANC).
10. The UE device as recited in claim 9 , wherein said GANC is a default GANC whose information is stored in said UE device.
11. The UE device as recited as recited in claim 8 , wherein said wireless access network node comprises an Unlicensed Mobile Access (UMA) network controller (UNC).
12. The UE device as recited in claim 9 , wherein said UNC is a default UNC whose information is stored in said UE device.
13. The UE device as recited in claim 8 , wherein the list of available WACNs is from the one or more WACNs of the WACN space coupled to said wireless access network node.
14. The UE device as recited in claim 8 , wherein the message is a registration request message.
15. The UE device as recited in claim 8 , further includes a storage device that stores an IP address in said UE device, said IP address for identifying said wireless access network node.
16. A network system, comprising:
a wireless access 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; and
a user equipment (UE) device configured to:
gain Internet Protocol (IP) connectivity with said wireless access network node;
send a message towards said wireless access network node, wherein said message includes location information associated with said UE device and at least one information element pertaining to wireless access services required by said UE device, wherein said message is initiated towards said wireless access network node after a successful discovery procedure or a failed registration with a serving access network node;
receive, from said wireless access network node, a response message comprising a list of available WACNs based on the location information associated with said UE device and the AN services required by said UE;
select a WACN from the list of available WACNs; and
store a Fully Qualified Domain Name (FQDN) in said UE device, said FQDN for facilitating a Domain Name Query (DNS) with respect to an IP address of said wireless access network node.
17. The network system as recited in claim 16 , wherein the list of available WACNs is from the one or more WACNs of the WACN space coupled to said wireless access network node.
18. The network system as recited in claim 16 , wherein said wireless access network node comprises a generic access network controller (GANC).
19. The network system as recited in claim 18 , wherein said GANC is a default GANC whose information is stored in said UE device.
20. The network system as recited in claim 16 , wherein said wireless access network node comprises an Unlicensed Mobile Access (UMA) network controller (UNC).
