A portable telephone control system in which a restricted format for a call origination and incoming call acceptance can be set by a controller for a restricted area A, and the use of mobile telecommunication terminals can be restricted by using a specially-defined channel. The portable telephone control system has a restriction control device 101, used for outputting a restricted signal 117 representing a restricted format over a restriction channel defined inside the restricted area A, and has a portable telephone 103 provided in the restricted area A for processing that corresponds to the restricted format for call origination and incoming call acceptance in response to the restriction signal 117.
