  • Patent number: 9144019
    Abstract: A network searching method adapted to a mobile electronic device in a no service state is provided. In the method, a first timer is activated. A network searching operation is performed. Whether an available network is found is determined. If the available network is not found, whether a time count of the first timer is smaller than a network searching active interval is determined. If the time count is not smaller than the network searching active interval, a second timer is activated. Before a network searching inactive interval set up by the second timer expires, the mobile electronic device is controlled to remain in a power save mode. If the time count is smaller than the network searching active interval, a third timer is activated. When a sleep interval set up by the third timer expires, the mobile electronic device is controlled to perform the network searching operation again.

  • Patent number: 8761120
    Abstract: A method of handling cell change for a mobile device employing a high speed downlink package access (HSDPA) technology in wireless communication systems. The method includes initiating a handover procedure to change a serving cell of the mobile device when the mobile device moves from a HSDPA cell into another HSDPA cell, performing a physical channel reconfiguration procedure from a high speed physical downlink shared channel (HS-PDSCH) to a dedicated physical data channel (DPDCH), wherein the physical channel reconfiguration procedure is initiated via a Radio Network Controller (RNC), and performing the handover procedure.

  • Publication number: 20120071177
    Abstract: A method of discontinuous reception (DRX) for a user equipment in a wireless communication system includes triggering a DRX function, prolonging a DRX cycle indicated by a network terminal of the wireless communication system with a predetermined multiple, and monitoring at least one paging message outputted from the network terminal according to the prolonged DRX cycle.
