Abstract:
1. 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 camps on a first serving cell belonging to the first PLMN, and the second subscriber identity card corresponds to a second PLMN and camps on a second serving cell belonging to the second PLMN, the communication apparatus comprising: processor logic coupled to the first subscriber identity card, the second subscriber identity card and the radio transceiver module, receiving a first neighbor cell list comprising a corresponding channel frequency of at least one neighbor cell of the first serving cell via the radio transceiver module, receiving a second neighbor cell list comprising a corresponding channel frequency of at least one neighbor cell of the second serving cell via the radio transceiver module; processor logic merging the first neighbor cell list and the second neighbor cell list to obtain a merged neighbor cell list; and processor logic tuning the radio transceiver module to the corresponding channel frequency/frequencies of the neighbor cells in the merged neighbor cell list to respectively receive a plurality of signals from the neighbor cells therein, and accordingly measuring and evaluating quality of the neighbor cells therein.
