Generic access network (GAN) controller selection in PLMN environment
A method for network selection on a user equipment (UE) device and the UE device are shown. The user equipment device registers on a first network in a wide area cellular network (WACN) band and receives, from a wireless local area network (WLAN), a list of WACNs that support generic access network (GAN) capabilities. The user equipment device selects the WLAN if the first network is on the list.
1. A method, operable on a user equipment (UE) device, for network selection, the method comprising:
registering on a first network in a wide area cellular network (WACN) space; and
while the UE device is registered on the first network:
receiving, from a wireless local area network (WLAN), a list of one or more networks in the WACN space, wherein each network of the one or more networks connects to the WLAN; and
selecting, by the UE, the WLAN in response to the UE determining that the first network on which the UE device is registered is on the list of the one or more networks in the WACN space.
2. The method according to claim 1 , further comprising authenticating with the WLAN.
3. The method according to claim 2 , further comprising handing over a service from the first network to the WLAN.
4. The method according to claim 3 , wherein the service is a telephony service.
5. The method according to claim 3 , wherein the service is a packet-switched data service.
6. The method according to claim 1 , wherein the first network appears as an entry in an operator-controlled Preferred PLMN list.
7. The method according to claim 1 , wherein the first network appears as an entry in an user-controlled Preferred PLMN list.
8. A user equipment (UE) device, comprising:
at least one hardware processor; and
a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions, when executed, cause the at least one hardware processor to perform operations comprising:
registering on a first network in a wide area cellular network (WACN) space; and
while the UE device is registered on the first network:
receiving, from a wireless local area network (WLAN), a list of one or more networks in the WACN space, wherein each network of the one or more networks connects to the WLAN; and
selecting, by the UE, the WLAN in response to the UE determining that the first network on which the UE device is registered is on the list of the one or more networks in the WACN space.
9. The UE device according to claim 8 , the operations further comprising authenticating with the WLAN.
10. The UE device according to claim 9 , the operations further comprising handing over a service from the first network to the WLAN.
11. The UE device according to claim 10 , wherein the service is a telephony service.
12. The UE device according to claim 10 , wherein the service is a packet-switched data service.
13. The UE device according to claim 8 , wherein the first network appears as an entry in an operator-controlled Preferred PLMN list.
14. The UE device according to claim 8 , wherein the first network appears as an entry in an user-controlled Preferred PLMN list.
15. A non-transitory computer-readable medium storing instructions which, when executed, cause a computing device to perform operations comprising:
registering on a first network in a wide area cellular network (WACN) space; and
while a user equipment (UE) device is registered on the first network:
receiving, from a wireless local area network (WLAN), a list of one or more networks in the WACN space, wherein each network of the one or more networks connects to the WLAN; and
selecting, by the UE, the WLAN in response to the UE determining that the first network on which the UE device is registered is on the list of the one or more networks in the WACN space.
16. The non-transitory computer-readable medium according to claim 15 , the operations further comprising authenticating with the WLAN.
17. The non-transitory computer-readable medium according to claim 16 , the operations further comprising handing over a service from the first network to the WLAN.
18. The non-transitory computer-readable medium according to claim 17 , wherein the service is a telephony service.
19. The non-transitory computer-readable medium according to claim 17 , wherein the service is a packet-switched data service.
20. The non-transitory computer-readable medium according to claim 15 , wherein the first network appears as an entry in an operator-controlled Preferred PLMN list.
