PROBLEM TO BE SOLVED: To allow a terminal equipment installation of each base station or the like to down-load data in a short waiting time and to surely find out destruction of the data in the case that a program or the like is changed by configuring the method such that the version check processing of the program is conducted not by a controller but by each base station. SOLUTION: A download processing section 25 of a base station 2 requests check sum data of an entire program to a controller 1 at the start. The controller 1 sends the check sum data stored in a register 12 to the base station 2 in response to the download request from the base station 2. A comparison section 24 of the base station 2 compares whether or not the check sum data sent from the controller 1 with check sum data stored in a register 22. In the case that the both are dissident, the download processing section 25 sends a download request of the program to the controller 1, and the controller 1 downloads the program stored in a memory 11 to the base station 2. |
