Aspects of the present disclosure provide techniques and apparatus for wireless communication. In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE) that may support a first radio access technology (RAT) and a second RAT. The method generally includes: attempting to communicate with a base station (BS) of the first RAT; in response to an event, stopping the attempt to communicate with the BS of the first RAT; in response to stopping the attempt to communicate with the BS of the first RAT, attempting to connect to the second RAT; and in response to a successful connection to the second RAT: identifying a first value of a parameter associated with the event; comparing the value to a second value; and determining whether to perform an action associated with the first RAT based at least in part on the comparing.

Apparatus and methods for reducing power usage in user equipments

A method for reducing call failure rates on a multi-subscriber identity module (SIM) mobile communication device includes: selecting a first SIM camped on a visiting public land mobile network (VPLMN); attempting call initiation on the first SIM; determining whether call setup on the first SIM on the VPLMN is successful; in response to determining that the call setup on the first SIM is unsuccessful, determining if a second SIM is camped on a home public land mobile network (HPLMN); and in response to determining that the second SIM is camped on the HPLMN, selecting the second SIM camped on the HPLMN; and attempting call initiation using the second SIM.

Reducing call failure rate in multi-subscriber identity module capable devices

A method for playing a local ringback tone is disclosed. A second party device is called from a calling party device. An alert message indicating that the calling party device is to play a network ringback tone is received. It is determined whether to play a pre-stored local ringback tone instead of the network ringback tone. The local ringback tone or the network ringback tone is played based on the determination. At any time before call connection or call release, the local ringback tone and the network ringback tone are switched between based on user input.
