摘要

The communication system by this invention, through the radio net, accommodates the portable terminal, possesses with the terminal data gathering device which controls the measurement of the propagation environmental quality which is done by the portable terminal inside the area according to the communication quality of the network monitor and the whole area which watch the communication quality of the whole area. With this kind of constitution, the measurement load in the portable terminal which relates to this invention can be modified according to the communication quality of the whole area. For example, it can lighten the measurement load of the portable terminal by prohibiting the quality measurement operation by the portable terminal according to the communication quality of the whole area.
