Abstract

A communication apparatus is provided. A first subscriber identity card camps on a first cell belonging to a first wireless network via at least one radio transceiver module. A second subscriber identity card camps on a second cell belonging to a second wireless network via the radio transceiver module. A memory device stores a plurality of phonebook entries each comprising a destination address and information indicating one of the first and second subscriber identity cards as a preferred subscriber identity card for the destination address. A processor receives an apparatus originated communication request with a first destination address, determines the preferred subscriber identity card for the received first destination address by inspecting the phonebook entries, and establishes a wireless communication with a peer device with the received first destination address through one of the first cell and the second cells in response to the determined preferred subscriber identity card.

6. The communication apparatus as claimed in claim 5, wherein the processor further stores a new phonebook entry comprising the second destination address and information indicating one of the first and second bearers as a preferred bearer for the second destination address according to the obtained information via the MMI.

7. The communication apparatus as claimed in claim 4, wherein the bearer is a voice call, a data call, a video call or a voice over Internet Protocol (VOIP) call.

8. The communication apparatus as claimed in claim 1, wherein at least one of the first subscriber identity card and the second subscriber identity card is the subscriber identity module (SIM) card corresponding to the global system for mobile communications (GSM), the universal subscriber identity module (USIM) card corresponding to the universal mobile telecommunications system (UMTS), or the removable user identity module (RUIM) card or the CDMA subscriber identity module (CSIM) card corresponding to the code division multiple access (CDMA) 2000 communication system.

9. The communication apparatus as claimed in claim 1, wherein the memory device further stores at least one identity each corresponding to a subscriber identity card has or had been inserted therein, and wherein the processor further detects whether the subscriber identity card corresponding to the identity of the memory device is replaced with at least one of the first and second subscriber identity cards by comparing the identity of the memory device with an identity corresponding to the first subscriber identity card and an identity corresponding to the second subscriber identity card, and when detecting the replacement, the processor updates at least one of the identities stored in the phonebook entries corresponding to the subscriber identity card being removed with the identity corresponding to the first or second subscriber identity card newly inserted.

10. The communication apparatus as claimed in claim 9, wherein the identity corresponding to a subscriber identity card is the international mobile subscriber identity (IMSI).

11. The communication apparatus as claimed in claim 9, wherein the identity corresponding to a subscriber identity card has or had been inserted therein is stored in a non-volatile region of the memory device.

12. A method for processing an apparatus originated communication request of a communication apparatus, wherein the communication apparatus comprises at least one radio transceiver module, a first subscriber identity card camping on a first cell belonging to a first wireless network via the radio transceiver module, a second subscriber identity card camping on a second cell belonging to a second wireless network via the radio transceiver module, a memory device storing a plurality of phonebook entries each comprising an address and information indicating one of the first and second subscriber identity cards as a preferred subscriber identity card for the address, and at least one processor coupled to the first subscriber identity card, the second subscriber identity card, the memory device and the radio transceiver module for controlling the operation thereof, the method comprising:
