Patent ID: 8204516

Claim:
A communication apparatus accompanying with a radio transceiver module, a first subscriber identity card camping on a first cell and a second subscriber identity card camping on a second cell for transceiving data via the first cell belonging to a first wireless network and the second cell belonging to a second wireless network, comprising: a processor coupled to the radio transceiver module, the first subscriber identity card and the second subscriber identity card, obtaining information regarding a plurality of first paging occasions distributed within a predetermined time interval for the first subscriber identity card, obtaining information regarding a plurality of second paging occasions distributed within the predetermined time interval for the second subscriber identity card; a processor detecting a forthcoming time slot of the predetermined time interval in which one of the first paging occasions collides with one of the second paging occasions; a processor determining listening to one of the first cell and the second cell in the detected time slot according to at least one of a plurality of decision rules; and a processor notifying of the determination to the radio transceiver module so as to direct the radio transceiver module to listen to the determined cell to receive a corresponding paging message from the determined cell in the detected time slot, wherein the decision rules comprises: determining a least recently listened cell among the first and second cells, determining a cell having a longer waiting time period to be listened to among the first and second cells, determining a cell having a better signal quality among the first and second cells, determining a cell having a predicted paging acquisition percentage lower than a guaranteed probability among the first and second cells, and randomly determining a cell among the first and second cells.
