Abstract
A mobile communications system is provided that automatically restricts a portable communications terminal which conducts communications at places such as hospitals where the uses of portable communications terminals are prohibited. A mobile communications system, which controls mobile communications of user terminals, includes a use prohibition area registration table, a location information management table, and a terminal location manager. The use prohibition area registration table records location data about locations within a use prohibition area where communications of the user terminal is not allowed. The location information management table records data about a current location of each user terminal, informed from the user terminal. The terminal location manager detects a user terminal within a use prohibition area based on data on the use prohibition area registration table and based on data on the location information management table and controls such that the user terminal does not communicate within the use prohibition area. Each user terminal includes a location detector for detecting a current location of the user terminal, and means for notifying the communication limiter of data about the current location of the user terminal detected by the location detector.
