  • Patent number: 8738081
    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.

  • Patent number: 8213989
    Abstract: A method for transmitting mobile originated requests by a mobile station with a first subscriber identity card and a second subscriber identity card, executed by a processor, is provided. It is determined whether a preference setting has been enabled. A preferred subscriber identity card is obtained from the first subscriber identity card and the second subscriber identity card when the preference setting has been enabled. The mobile originated request is issued to a called party via the preferred subscriber identity card when the preference setting has been enabled.

  • Patent number: 8108002
    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.

  • Publication number: 20090259974
    Abstract: A display method for displaying content menus for use in a mobile device is disclosed. The method comprises the following steps. First, a user request is received. Second, display brief of actual data is acquired from an entry of an index file of a non-volatile storage medium according to the user request. Thereafter, a content menu comprising a menu item with the display brief is generated. Then, the generated content menu is displayed, wherein the entry further comprises information pointing to a location which the actual data stores in the non-volatile storage medium, the display brief is a reduced form of the actual data, and the actual data is displayed when the menu item is selected.
