  • Method for searching cells in mobile communication system
    Patent number: 6452912
    Abstract: A rapid cell search method is disclosed for a mobile station in a mobile communication system. Upon detection of a power-off request, the mobile station stores in a memory PN information of adjacent cells in association with receiving power levels of the adjacent cells. Upon power on, it is determined whether the mobile station is presently located in a same cell group where it was located at a power-off time. When the mobile station is located in the same cell group, it sequentially reads the PN information from the memory in order of receiving power level to search the adjacent cells. Further, the mobile station searches a cell registered at the power-off time prior to searching the adjacent cells.
