PURPOSE:To prevent the existence of same mobile equipment data in plural BC stations 2a, 2b by transferring a newest mobile set data belonging to a slave exchange (BC) station from a control exchange (CC) station to the BC station at the restoration of a faulty wired line and allowing the BC station to update a database of its own station based on the data transfer. CONSTITUTION:When a fault of a wired line 7b is restored and the operation of a BC station 2b is started, A CC station 1 uses a newest data transfer means 9 to read a newest mobile set data belonging to the BC station 2b managed by a database 3a and transfers the data to the BC station 2b via the restored wired line 7b. The BC station 2b receives the newest mobile set data by a management data update means 10, which updates the mobile set data managed in a database 3c of its own station based on the received newest mobile set data. Thus, the existence of a same mobile set data in plural BC stations is avoided and the load of the data transfer is relieved. |
