Cell Search Control Method, Cell Search Control Apparatus, Mobile Communication Terminal, Computer Program and Storage Medium

摘要

The embodiments disclose a cell search control method, a cell search control apparatus, a mobile communication terminal, a computer program and a storage medium. A first communication subsystem losing coverage in an access network perform cell search using a list of neighboring cells provided by a second communication subsystem covered by other access network, rather than performs cell search in a full-band searching manner, so as to reduce the power consumption of the mobile communication terminal when it recovers service from the loss of coverage. When the list of cells remains unchanged and the first communication subsystem cannot successfully camp on a cell after a first number of attempts, a time interval (period) of cell search procedure performed by the first communication subsystem based on the list of cells will be increased, so as to avoid meaningless search under the circumstance of poor network quality, and to reduce the power consumption of the mobile communication terminal.

主权项

1. A cell search control method, used for a mobile communication terminal, the mobile communication terminal comprising a first communication subsystem capable of accessing a first access network and a second communication subsystem capable of accessing a second access network, the first communication subsystem and the second communication subsystem being able to provide a user with services simultaneously based on one identical (U)SIM, the cell search control method comprising:
acquiring, when the coverage for the mobile communication terminal in the first access network is lost, system information received by the second communication subsystem, wherein the mobile communication terminal currently camping on a cell of the second access network; selecting part or all of the cells belonging to the first access network from neighboring cells recorded in the system information to form a list of cells; and controlling the first communication subsystem to perform cell search procedure based on the list of cells, wherein, when the first communication subsystem cannot successfully camp on the cells meeting the requirements after a first number of times of cell search procedure in a first time interval (period) based on the list of cells, the first time interval of cell search procedure performed by the first communication subsystem based on the list of cells is increased.
