A proposed system has been proposed. FIG. 7 shows the basic configuration of this type of system. This system comprises a radio line controller 2 to which a plurality of subscriber lines 11, 12 are connected, and a plurality of extensions 31 to 31 of the radio line controller 2. 3n and wireless connection devices 41 to 4n respectively connected to,
It is composed of wireless telephones 61 and 62 connected to these wireless connection devices 41 to 4n via the wireless line 5. Incidentally, 71
7n are communication areas of the wireless connection devices 41-4n.

By the way, in this type of system, the wireless connection devices 41 to
In order to cope with movement or replacement of 4n, expansion, etc., system generation data including an identification code and an operation mode is preset for each of the wireless connection devices 41 to 4n, and the movement of the wireless connection devices 41 to 4n is performed. In this case, the system generation data is downloaded from the wireless channel control device 2 to the wireless connection devices 41 to 4n. However, the conventional system downloads the system generation data every time the radio channel controller 2 is started. Therefore, for example, when the wireless connection devices 41 to 4n are moved, replaced, expanded, or the like while the system is operating, the download is performed when the wireless channel control device 2 is started, for example, when the system is started the next morning. As a result, the setting of the system generation data is delayed.

(Problems to be Solved by the Invention) As described above, in the conventional system, when the wireless connection device is moved, replaced, expanded, or the like, the download of system generation data accompanying the movement is waited until the start of the wireless line control device. The present invention focuses on this point, so that even when the system is operating, the system generation data can be immediately downloaded when necessary, thereby increasing the number of wireless connection devices. The purpose of the present invention is to provide a wireless telephone system capable of promptly responding to the problem.

When the arrival of the load request is detected, the download control means C sends out the system generation data to the wireless connection device that has sent the load request and sets it.

(Operation) As a result, when the wireless connection device is moved, replaced or added, and activated, the wireless connection device sends a load request for system generation data to the wireless line control device. Since the system generation data is downloaded from the control device to the wireless connection device, the system generation data is immediately downloaded without stopping the system and without waiting for the activation of the wireless line control device. Thus, the wireless connection device that has been moved, replaced, added, or the like can be quickly used.
