Abstract: The present disclosure presents a method and an apparatus for packet filtering to save power at a user equipment (UE). For example, the disclosure presents a method for receiving a packet filtering configuration message, at a modem processor (MP) of the UE, from an application processor (AP) in communication with the MP, wherein the packet filtering configuration message includes one or more packet filtering rules for filtering packets associated with one or more applications, configuring a packet filter at the MP based at least on the one or more packet filtering rules received in the packet filtering configuration message, and enabling the configured packet filter at the MP in response to receiving an indication from the AP that the AP entered a low power or sleep mode, wherein the enabled packet filter allows or drops a packet based on the packet filtering rules. As such, packet filtering to save power at UE may be achieved.

Abstract: Methods and apparatus are provided for avoiding attempts by a UE to attach to a RAT network when that RAT network is unavailable. According to certain aspects, the UE may detect scenarios when the RAT network is unavailable and take preemptive action to prevent the UE from attempting to acquire service on that RAT. For example, the UE may effectively remove that RAT from a list of supported RATs by sending a UE capability message indicating that RAT is not supported, which may prevent network-initiated transitions of the UE to that RAT. The UE may also remove the unavailable RAT from an internal list of supported RATs, which may prevent UE-initiated transitions to that RAT.
