PURPOSE:To increase a processable traffic quantity by registering a fixed radio equipment with a high receiving level to a communication control unit when a position informing signal from a fixed radio equipment except the registered fixed radio equipment is received by the receiving level higher than the prescribed receiving level. CONSTITUTION:When a radio zone 51 of a position registered fixed radio equipment, for example 41, is only one and the position informing signal from other fixed radio equipment 42 is also received over a prescribed level, it is considered that a mobile radio equipment 3a exists at the position where at least two radio zones 51 and 52 are superimposed. By registering these two radio zones 51 and 52, the radio line can be composed of at least two channels. Thus, the traffic quantity can be increased in which the processing as a system can be performed. |
