摘要： An acknowledgement technique reduces packet-switched communication delays. The technique may be implemented in a mobile communication device with multiple SIMs. The technique facilitates enhanced communication capability for the mobile communication device. In one implementation, the technique helps reduce delays caused by switching between packet-switched and circuit-switched communications. Specifically, in one aspect, the technique reduces delays caused by exponential backoff that may occur during suspension of a packet-switched communication.

摘要： Systems and methods are presented to support operation of a multiple subscriber identity module (SIM) device. A timing conflict may exist when a scheduled high priority communication of a first SIM overlaps with a scheduled paging monitoring activity for a second SIM. The multiple SIM device may preempt transitioning communication resources to the second SIM when the first SIM executes high priority communications. Or, the multiple SIM device may execute a rescheduling action to resolve the timing conflict. The high priority communication of the first SIM may be rescheduled. Alternatively, normal priority paging monitoring actions may be rescheduled to resolve the timing conflict.
