Methods for integrating cell measurement procedures of a communication apparatus and communication apparatuses utilizing the same

A communication apparatus is provided. The communication apparatus includes a processor, a first and a second subscriber identity card and at least one radio transceiver module. The processor is coupled to the first subscriber identity card, the second subscriber identity card and the radio transceiver module, merges a first neighbor cell list and a second neighbor cell list to obtain a merged neighbor cell list, tunes the radio transceiver module to the corresponding channel frequency/frequencies of the neighbor cells in the merged neighbor cell list to respectively receive signals from the neighbor cells therein, and accordingly measures and evaluates quality of the neighbor cells therein.
