Patent ID: 8200225

Claim:
A communication apparatus having at least one radio transceiver module, a first subscriber identity card and a second subscriber identity card, where the first subscriber identity card corresponds to a first public land mobile network (PLMN), and the second subscriber identity card corresponds to a second PLMN, the communication apparatus comprising: processor logic determining whether the first PLMN and the second PLMN are the same; processor logic, when the first and the second PLMNs are the same, suspending a measurement procedure and a cell reselection procedure of one of the first subscriber identity card and the second subscriber identity card to reduce battery power consumption; processor logic triggering an unsuspended measurement procedure to tune the radio transceiver module to a plurality of corresponding channel frequency/frequencies of the neighbor cells to respectively receive a plurality of signals from the neighbor cells therein, and accordingly measuring and evaluating quality of the neighbor cells therein; and processor logic triggering an unsuspended cell reselection procedure to determine whether to reselect one neighbor cell with better quality than that of the corresponding serving cell according to measurement and evaluation results.
