A communications apparatus is provided. A processor is coupled to a subscriber identity card and a radio transceiver module. The subscriber identity card camps on a first cell operated in a first serving network having a first serving network identifier via the radio transceiver module. The processor embeds information regarding the first serving network identifier in a first signal and transmits the first signal to a peer communications apparatus via the radio transceiver module.

Methods for providing serving network information and communications apparatuses utilizing the same

A communication apparatus is provided. A processor camps on a first cell, which is associated with a first radio access technology (RAT) and belongs to a first wireless network, via a radio transceiver module, and further camps on a second cell, which is associated with a second RAT and belongs to a second wireless network, via the radio transceiver module. The processor constructs a first packet switch connection with the first wireless network via the first cell to perform data transfer in the first wireless network, measures a first data transfer throughput of the first wireless network when performing the data transfer via the cell, and determines to perform the data transfer in the second wireless network via the second cell when a theoretical data transfer throughput corresponding to the second RAT is higher than the first data transfer throughput.

Method for selecting optimal radio access technology and communication apparatuses utilizing the same

A wireless communication device for enhancing a data rate for a packet-switched (PS) data service is provided. The device comprises a processor configured to reference cell information corresponding to a first subscriber identity card to maintain mobility for a second subscriber identity card by using the referenced cell information when performing the PS data service with a first service network for the first subscriber identity card.
