  • Patent number: 9313709
    Abstract: An embodiment of a method for call management, performed by a processing unit of a UE (user equipment), is disclosed. The method is employed in a hardware configuration of at least two subscriber identity cards sharing a radio resource. A PS (packet-switched) service is first provided for the first subscriber identity card. Packet data transmission and reception is handed over to a second PS service with the second subscriber identity card from the first PS service after receiving a call request requesting a CS (circuit-switched) service with the second subscriber identity card.
    Type: Grant

  • Patent number: 8463277
    Abstract: A method for allocating paging resource to a mobile station, communicating with a communication network and having multiple subscriber identities, includes: allocating paging resource to the mobile station according to a first equipment identity and a first subscriber identity of the mobile station when the first equipment identity and the first subscriber identity are received for registration, and allocating the same paging resource to the mobile station when the first equipment identity and a second subscriber identity of the mobile station are received for registration, transmitting a paging message targeting at the first subscriber identity at a paging block with a first block index, and transmitting a paging message targeting at the second subscriber identity at a paging block with the first block index.

  • Patent number: 8463198
    Abstract: A communication apparatus is provided. A processor receives a measurement control message carrying information about a filtering coefficient via a radio transceiver module, periodically measures signal quality of at least one cell to obtain a plurality of measurement results, periodically filters the measurement results according to a first measurement period to obtain a plurality of filtered results, and determines whether to transmit a measurement report to a system controller in the wireless communication network according to the filtered results. The filtering coefficient is assigned by the system controller to filter the measurement results according to a second measurement period.

  • Patent number: 8274938
    Abstract: The invention discloses a method for coordinating protocol stack entities to share a single radio resource, executed by a processor of a mobile station, including the step of: after a first protocol stack entity for a first subscriber identity card enters a TALKING mode or enables a dial-up service, forcing a second protocol stack entity for a second subscriber identity card to release the radio resource or suspend utilization of the radio resource, and enabling the radio resource to be utilized to perform requisite operations or procedures of the TALKING mode or the dial-up service.
