Abstract

PURPOSE:To prevent momentary interruption of communication by using a 2nd channel so as to confirm the communication quality to be a prescribed value or over if the communication quality is deteriorated less than a prescribed quality during the communication through the use of a 1st radio channel so as to switch the channel to the 2nd radio channel. CONSTITUTION:While one radio base station 30-1 and a mobile radio equipment use one channel (old channel) for communication, if the communication quality is deteriorated less than a prescribed criterion, prior to the communication through the changeover of other channel (new channel) with other radio base station 30-2 satisfying a prescribed communication quality, a changeover transmission means 23 is switched at a speed not giving effect on the communication signal thereby sending data with tentative parallel operation of both the old and new channels. Then the quality of the new channel is checked and when it is confirmed the quality meets the requirements, the switching is finished and the communication is attained through the new channel only. Thus, momentary interruption of communication by channel changeover is not caused.
