To prevent loop of line from occurring and to surely repeat a telegraphic message from a center to a final destination device by attaching a code, to indicate whether a line can be connected to radio communication equipment at the last destination by relaying one or plural pieces of radio communication equipment.

Pieces of received field intensity value data received by each PHS communication equipment are collected by an instruction of an input device 34 connected with the center controller 30, and an information table for repeating is generated by a center controller 30 of a metering data collection center device 101. A broadcast instruction telegraphic message signal for instructing transmission of a response telegraphic message signal including metering data and a received field intensity value from each PHS communications equipment to the device 101 is generated, transmitted to each PHS communications equipment via a terminal adapter 32, a DSU 33, the ISDN 300, PHS base station equipment and returned to the device 101 by a center control part 30 via other communication equipment in response to transmission from each PHS communication equipment. No loop of line link occurs in the information table for repeating generated in this way.
