Wireless communication devices and methods for performing a packet-switched (ps) service applied to a mobile communications device with multiple subscriber identity modules (sims)

摘要

A wireless communication method for performing a packet-switched (PS) data service in a mobile communications device with a plurality of subscriber identity modules (SIM) is provided. A PS service is first performed with a first subscriber identity module. During performing the PS service with the first subscriber identity module, it is then determined packet loss status regarding whether a packet in the downlink transmission have been successfully received. A frequency for receiving signals on control channel or circuit-switched channel associated with the first subscriber identity module or signals on control channel or circuit-switched channel or packet-switched channel associated with a second subscriber identity module is adaptively adjusted according to the determination result while performing the PS service with the first subscriber identity module.
