Abstract

A communication apparatus is provided. A first subscriber identity card camps on a first cell belonging to a first wireless network via a radio transceiver module and stores first contact entries each having a destination address. A second subscriber identity card camps on a second cell belonging to a second wireless network via the radio transceiver module and stores second contact entries each having a destination address. A processor receives an apparatus originated communication request with a destination address, determines whether the received destination address is currently stored in one of the first contact entries of the first subscriber identity card or one of the second contact entries of the second subscriber identity card, and transmits the apparatus originated communication request to the cell that the determined subscriber identity card camps on to establish a wireless communication with a peer device associated with the received destination address.

a processor coupled to the first subscriber identity card, the second subscriber identity card and the radio transceiver module, receiving an apparatus originated communication request with a destination address, determining whether the received destination address is currently stored in one of the first contact entries of the first subscriber identity card or one of the second contact entries of the second subscriber identity card, and transmitting the apparatus originated communication request to the cell that the determined subscriber identity card camps on to establish a wireless communication with a peer device associated with the received destination address.

2. The communication apparatus as claimed in claim 1, wherein the apparatus originated communication request is a voice communication request, a data communication request, a video communication request, a short message service (SMS) communication request, or a voice over Internet Protocol (VOIP) communication request.

3. The communication apparatus as claimed in claim 1, further comprising a memory device coupled to the processor and storing a plurality of third contact entries, wherein a portion of the content of the third contact entries is copied from the first and second contact entries, and each third contact entry further comprises origination information indicating where partial content of this entry is copied from, and wherein the processor further determines whether the destination address is currently stored in one of the first contact entries or one of the second contact entries by inspecting the origination information of the third contact entries.

4. 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) communication system, the universal subscriber identity module (USIM) card corresponding to the universal mobile telecommunications system (UMTS) communication system, 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.

5. The communication apparatus as claimed in claim 1, wherein the processor further issues commands to the first and second subscriber identity cards and determines whether the destination address is currently stored in one of the first contact entries or one of the second contact entries according to reply results.

6. The communication apparatus as claimed in claim 1, wherein each destination address comprises a series of numbers representing a phone number.

7. The communication apparatus as claimed in claim 1, wherein each destination address comprises a series of numbers representing an Internet Protocol (IP) address.

8. A communication apparatus, comprising:

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, and storing a plurality of first contact entries each comprising a destination address;

a second subscriber identity card camping on a second cell belonging to a second wireless network via the radio transceiver module, and storing a plurality of second contact entries each comprising a destination address; and

a processor coupled to the first subscriber identity card, the second subscriber identity card and the radio transceiver module, receiving message data and an apparatus originated communication request with a plurality of destination addresses, determining whether each received destination address is currently stored in one of the first and second subscriber identity cards, grouping the destination addresses currently stored in the first contact entries into a first group, grouping the destination addresses currently stored in the second contact entries into a second group, sending the message data to the destination addresses of the first group via the first cell and sending the message data to the destination addresses of the second group via the second cell.

9. The communication apparatus as claimed in claim 8, wherein the message data is short message service (SMS) data or multimedia message service (MMS) data.

10. The communication apparatus as claimed in claim 8, further comprising a memory device coupled to the processor and storing a plurality of third contact entries, wherein a portion of the content of the third contact entries is copied from the first and second contact entries, and each third contact entry further comprises origination information indicating where partial content of this entry is copied from, and wherein the processor determines whether each destination address is currently stored in the first or second subscriber identity card by inspecting the origination information of the third contact entries.

11. The communication apparatus as claimed in claim 8, 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) communication system, the universal subscriber identity module (USIM) card corresponding to the universal mobile telecommunications system (UMTS) communication system, 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.

12. The communication apparatus as claimed in claim 8, wherein the processor further issues commands to the first and second subscriber identity cards and determines whether the destination address is currently stored in the first or second subscriber identity card according to reply results.

13. A communication apparatus, comprising:

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; and

a processor coupled to the first subscriber identity card, the second subscriber identity card and the radio transceiver module, receiving an apparatus originated communication request with a plurality of destination addresses for establishing a wireless conference communication with a plurality of peer devices having the received destination addresses, determining whether each received destination address corresponds to one of the first and second subscriber identity cards, sending the apparatus originated communication request to the first cell when most of the received destination addresses correspond to the first subscriber identity card, and sending the apparatus originated communication request to the second cell when most of the received destination addresses correspond to the second subscriber identity card.

14. The communication apparatus as claimed in claim 13, wherein the first subscriber identity card stores a plurality of destination addresses, the second subscriber identity card stores a plurality of destination addresses, the processor further determines whether each received destination address is currently stored in the first or second subscriber identity card, sends the apparatus originated communication request to the first cell when most of the received destination addresses are stored in the first subscriber identity card, and sending the apparatus originated communication request to the second cell when most of the received destination addresses are stored in the second subscriber identity card.
