WIRELESS COMMUNICATION BASE STATION SYSTEM, WIRELESS COMMUNICATION SYSTEM, AND WIRELESS MOBILE STATION

摘要

Once an MS's destination area has been determined, the MS receives a frequency list of BSs belonging to the destination area from a broadcasting BS before disconnecting the current network connection, and creates and stores several Search Configurations. When performing a cell search upon arrival at the destination area, the MS connects to a broadcasting BS in the destination and receives a frequency list of the BSs belonging to the destination area. The MS compares the frequency list that it maintains with the frequency list broadcasted from the BS in the destination and performs a cell search according to the result of the comparison. This leads to achieving reliable network connection and reducing time to establish connection.
