COMMUNICATION APPARATUSES EQUIPPED WITH MORE THAN ONE SUBSCRIBER IDENTITY CARD AND CAPABLE OF PROVIDING RELIABLE COMMUNICATION QUALITY
First Claim
1. 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 same or different radio transceiver modules;
a second subscriber identity card camping on a second cell belonging to a second wireless network via the same or different radio transceiver modules; and
a processor coupled to the first subscriber identity card, the second subscriber identity card and the radio transceiver module(s), receiving an apparatus originated communication request with a destination address, comparing a signal strength of a first signal received from the first cell with a signal strength of a second signal received from the second cell and establishing a wireless communication with a peer device having the destination address through the cell with better signal strength.

Abstract
A communication apparatus is provided. The communication apparatus includes at least one radio transceiver module, a first subscriber identity card, a second subscriber identity card and a processor. The first subscriber identity card camps on a first cell belonging to a first wireless network via the same or different radio transceiver modules. The second subscriber identity card camps on a second cell belonging to a second wireless network via the same or different radio transceiver modules. The processor, coupled to the first subscriber identity card, the second subscriber identity card and the radio transceiver module(s), receives an apparatus originated communication request with a destination address, compares a signal strength of a first signal received from the first cell with a signal strength of a second signal received from the second cell and establishes a wireless communication with a peer device having the destination address through the cell with better signal strength.

7. A communication apparatus, comprising:
-
at least one radio transceiver module; a first subscriber identity card with a first address camping on a first cell belonging to a first wireless network via the same or different radio transceiver modules; a second subscriber identity card with a second address 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(s), receiving a apparatus terminated communication request of the first subscriber identity card with an origination address from the first cell, comparing a signal strength of a first signal received from the first cell with a signal strength of a second signal received from the second cell and transmitting a redirection request through the first cell to the first wireless network via the radio transceiver module to instruct the first wireless network to redirect the apparatus terminated communication request to the second subscriber identity card when the signal strength of the second signal is better than the signal strength of the first signal. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A communication apparatus, comprising:
-
a single 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, transmitting a message through the second cell to the second wireless network via the radio transceiver module right after the first subscriber identity card has finished a wireless communication with a peer communication apparatus. - View Dependent Claims (15, 16, 17, 18, 19, 20)
