PURPOSE:To realize the mobile body communication system able to reduce a processing time for indexing a position registration zone being an object of incoming call processing by reducing information quantity without losing the efficiency of the incoming call processing. CONSTITUTION:An exchange 9 is provided with a database 7 in which specific base station information whose position registration zones 3a, 3b are resident adjacently is set with sequencing corresponding to each of base stations 2a, 2b,..., and with the function of executing incoming call processing to the base station to which a relevant mobile equipment makes position registration when a call comes to mobile equipments 4a, 4b and to a base station to which base station information is set corresponding to the base station of the database 7. The communication is smoothed such as reduction in incoming call disable number of times and the information quantity is saved without losing the efficiency of the incoming call processing and the index processing time of the position registration zone is reduced. |
