Abstract: A method and apparatus for selecting an access point (AP) for providing a service at a user equipment (UE). The example method may identify, by a user equipment (UE), a first AP available for communication. The example method may determine, by the UE, whether the first AP is suitable based, at least in part, on an indication for the first AP in an AP history table stored in a memory of the UE, wherein the indication is based on UE-determined metrics determined during one or more prior communications between the UE and the first AP. The example method may also include establishing communication between the UE and the first AP, in response to determining that the first AP is suitable.

Abstract: Techniques are described for wireless communication. One method includes determining at a first time that a voice call is routed over a wireless local area network (WLAN); restricting an application processor from entering a first sleep state based at least in part on determining that the voice call is routed over the WLAN; determining at a second time that the voice call is offloaded from the WLAN to a wireless wide area network (WWAN); and enabling the application processor to enter a second sleep state based at least in part on determining that the voice call is routed over the WWAN.

Abstract: Methods, systems, and devices for IMS based WWAN-WLAN mobility are described. A user equipment (UE) may generate channel quality metrics and media performance metrics for a source radio access technology (RAT). The UE may then select a state for the source RAT metrics. The UE may also generate channel quality metrics for a target RAT and select a state for the target RAT. The UE may make a handover decision based on the states of the RATs and on priority levels for the RATs.
