Abstract
A handover method for a mobile radio communications system, which reduces the disconnection time when the radio channel is switched from one radio base station to another radio base station. When the electric field received from a first radio base station weakens beyond a preset level during communication, the mobile station receives TDMA frames intermittently from other radio base stations without disconnecting communication with the first radio base station, and selects a second radio base station based on the strength of the received electric fields. In a similar manner, the mobile station then intermittently prepares for connection with the second radio base station while continuing the communication with the first radio base station.
