Abstract
In one embodiment, a method for wireless network selection includes obtaining, by a user equipment (UE) from a visitor access network discovery and selection function (V-ANDSF) server, a visitor policy and creating a wireless local area network (WLAN) priority list in accordance with the visitor policy, a home policy, and a priority indicator. The method also includes selecting a WLAN from the priority list as a selected network.
Claims22
A method for wireless network selection, the method comprising:
- obtaining, by a user equipment (UE) from a visitor access network discovery and selection function (V-ANDSF) server, a visitor policy;
- creating a first wireless local area network (WLAN) priority list in accordance with the visitor policy, a home policy, and a priority indicator, the priority indicator comprising a list of preferred visitor networks, wherein creating the first WLAN priority list comprises setting the first WLAN priority list to the visitor policy in response to a first visitor network to which the UE is roaming being included in the list of preferred visitor networks;
- selecting a first WLAN from the first WLAN priority list as a first selected network;
- creating a second WLAN priority list in accordance with the visitor policy, the home policy, and the priority indicator, wherein creating the second WLAN priority list comprises setting the second WLAN priority list to the home policy in response to a second visitor network to which the UE is roaming being excluded from the list of preferred visitor networks;
- and
- selecting a second WLAN from the second WLAN priority list as a second selected network.
3 more elements
A user equipment (UE), comprising:
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the non-transitory memory storage, wherein the one or more processors execute the instructions to:
- obtain, from a visitor access network discovery and selection function (V-ANDSF) server, a visitor policy;
- create a first wireless local area network (WLAN) priority list in accordance with the visitor policy, a home policy, and a priority indicator, the priority indicator including a list of preferred visitor networks, wherein the one or more processors executing the instructions to create the first WLAN priority list execute instructions to set the first WLAN priority list to the visitor policy in response to a first visitor network to which the UE is roaming being included in the list of preferred visitor networks;
- select a first WLAN from the first WLAN priority list as a first selected network;
- create a second WLAN priority list in accordance with the visitor policy, the home policy, and the priority indicator, wherein the one or more processors executing the instructions to create the second WLAN priority list execute instructions to set the second WLAN priority list to the home policy in response to a second visitor network to which the UE is roaming being excluded from the list of preferred visitor networks;
- and
- select a second WLAN from the second WLAN priority list as a selected network.
6 more elements
A non-transitory computer-readable media storing programming for execution by one or more processors, the programming including instructions for:
- obtaining, by a user equipment (UE) from a visitor access network discovery and selection function (V-ANDSF) server, a visitor policy;
- creating a first wireless local area network (WLAN) priority list in accordance with the visitor policy, a home policy and a priority indicator, the priority indicator comprising a list of preferred visitor networks, wherein the instructions for creating the first WLAN priority list include instructions for setting the first WLAN priority list to the visitor policy in response to a first visitor network to which the UE is roaming being included in the list of preferred visitor networks;
- selecting a first WLAN from the first WLAN priority list as a selected network;
- creating a second WLAN priority list in accordance with the visitor policy, the home Policy, and the priority indicator, wherein the instructions for creating the second WLAN priority list include instructions for setting the second WLAN priority list to the home policy in response to a second visitor network to which the UE is roaming being excluded from the list of preferred visitor networks;
- and
- selecting a second WLAN from the second WLAN priority list as a selected network.
