  • Patent number: 8774133
    Abstract: A cell measurement method used in a mobile station camping on a serving cell is provided, wherein the serving cell sends system information of neighbor cells to the mobile station. A first set of the neighbor cells is determined based on a measurement rule for cell reselection. A second set of the neighbor cells is determined based on a report request for radio link establishment. A subset is chosen from the second set. Finally, the neighbor cells of a union of the first set and the subset are measured.

  • Patent number: 8200283
    Abstract: A communication apparatus has at least one radio transceiver module, a first subscriber identity card with a first address and a second subscriber identity card with a second address. The first subscriber identity card camps on a first cell belonging to a first wireless network via the radio transceiver module, and the second subscriber identity card camps on a second cell belonging to a second wireless network via the radio transceiver module. The communication apparatus includes first processor logic coupled to the radio transceiver module, the first subscriber identity card and the second subscriber identity card, receiving a communication request requesting for establishing wireless communication between the first subscriber identity card and a peer communication entity.

  • Patent number: 8195234
    Abstract: A method for sharing a mobility status in a mobile station with a first subscriber identity card and a second subscriber identity card is provided. The mobility status indicating the movement extent of the mobile station is obtained by the first subscriber identity card being currently camping on a first cell of a first network operator. Settings corresponding to a mobility-dependent procedure for the second subscriber identity card being currently failure to camp on any second cell of a second network operator are configured, thereby enabling the mobility-dependent procedure to be performed with consideration of the obtained mobility status.

  • Patent number: 8064957
    Abstract: A communication apparatus is provided. A first subscriber identity card is with a first address and camps on a first cell. A second subscriber identity card is with a second address and camps on a second cell. After receiving a communication request requesting for establishing wireless communication between the first subscriber identity card and a peer communication entity, a processor activates a service instructing the second wireless network to transfer a future apparatus terminated communication request of the second subscriber identity card to the first subscriber identity card via the first cell.
