Method of selecting a cell to connect by radio with a mobile station and a mobile communications terminal therefor

摘要

A mobile communications system includes an RF processor for transmitting and receiving radio signals to and from a base station, and a base-band processor for spread-spectrum coding a frame signal to be transmitted to transfer it to the RF processor and spread-spectrum decoding a signal transferred from the RF processor to extract a frame signal. The base-band processor includes a rake receiver for demodulating the received signal and a cell selector and processor for selecting a cell to be connected based upon the propagation path and the power of the received signal. The cell selector and processor includes a search circuit for detecting a cell from the received signal, a cell operator for determining a cell from which received is a signal associated with a shorter propagation path, based on the reception timing of the received signal, and a connecting cell selector for selecting a cell to be connected.
