PURPOSE:To attain the communication by applying relay connection to other communication terminal equipment when the communication terminal equipment is available of signal relaying is in existence around a concerned communication equipment so as to establish synchronization even when the concerned communication terminal equipment is located at a dead zone. CONSTITUTION:The system is provided with one base station or over (21, 22), mobile communication terminal equipments 11-13, and a management station 31 acting like a host station to the base stations 21, 22 to manage and register position information of each communication terminal equipment. Then at least either of the communication terminal equipments 11, 12 is provided with a means relaying and sending information included in a signal sent through a 1st outgoing channel from the base station 21 to other 2nd outgoing channel than the 1st outgoing channel, and a means relaying and sending the information included in the signal subject to relaying and transmission and coming from a 2nd incoming channel corresponding to the 2nd outgoing channel to a 1st incoming channel corresponding to the 1st outgoing channel while being addressed to the base station. Thus, the information included in a control channel sent from the base stations 21, 22 is reached not only in an area covered by the base stations 21, 22 but also to the outside of the area.
