Abstract

PURPOSE:To attain channel changeover without hit by allowing a mobile equipment to switch a frequency of a local oscillator at a high speed for each time slot, to monitor sequentially radio waves from an adjacent radio base station except its communication to keep the decision of quality and deciding a transferred radio zone by the mobile equipment itself. CONSTITUTION:The mobile equipment 5 switches a transmission/reception channel (frequency and time slot) at a high speed, monitors sequentially radio waves from plural adjacent base station 2-4 except the time assigned to the communication to estimate the present position and decides the moving direction and the radio zone by itself. When the frequency of the mobile destination zone and time slot are assigned to a mobile equipment MSS, the mobile station communicates the base station 2 before the changeover into the transfer destination channel during the communication, an equalizer or the like is set to improve the characteristic in a new propagation line and the radio continuity test is conducted. In the signal transmission from the MSS to the radio base station MBS, so-called in the outgoing direction, even when no voice is sent during the communication, predetermined information is kept for the transmission, through an idle time slot. Thus, the channel is switched without hit.
