DISTRICT QUASI-NON-DESIGNATION DIAL MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE:To reduce the rate of ineffective use of a telephone network equipment by calculating a charging index from the combination between calling district information to which a Sent telephone subscriber temrinal equipment belongs and the present position checked from identification information of an opposite mobile terminal equipment included in the received dial information. CONSTITUTION:A central controller 22 in a mobile communication exchange 20 calculates the distance between a telephone set l and a mobile equipment 2 depending on the call district identification number received from a relay exchange 10 and the position information of the mobile equipment 2 Sent from a home mobile communication exchange 30 to decide the charging index corresponding thereto. The controller 22 compares the decided charging index with the charging index corresponding to the charging index identification number dialed by the telephone set l and sends the telephone number of the mobile equipment 2 to a mobile communciation exchange 40 accommodating a radio base station 50 communicated With the mobile equipment 2 When coincident. The exchange 40 calls the mobile equipment 2 to connect the call from the telephone set l. Thus, the convenience of the dial operation is improved and the rate of ineffective use of the telephone network installation is reduced. Further, the Subscriber number capacity is expanded.
