Systems and Methods for Using a Channel Access Scheme of a First Network to Synchronize With a Second Network During an Active Call on a Multi-SIM Device

摘要

Embodiment methods and devices enable use of a shared radio resource on a multi-SIM wireless communication device to maintain session information on a service associated with one SIM during unused time slots of an active communication session associated with another SIM. During the session, a processor may calculate radio idle time periods in the active communication session, determine whether any of the radio idle time periods will exceed a predetermined threshold duration, and retune the shared radio resource to receive search samples on a frequency of the non-active network during radio idle time periods that exceed the predetermined threshold duration. Search samples may be stored for processing between radio idle time periods in order to maintain session information on a service associated with one SIM and provide service information to applications executing on the device during the active communication session.
