An operation of registering location information of the mobile station 12 in a conventional radio telephone system will be described. Mobile station 1
The operator 2 selects one branch office which is closest to the mobile station 12 in the branch office county 5 and is considered to be optimal in terms of the circuit configuration. For example, when the first branch station 5-1 is selected, the mobile station 12 transmits the location information 14 to the first branch station 5-1. After being transmitted to the first branch office 5-1, the location information 14 is stored in the control office 1 and all the branch offices 5-2 except the first branch office 5-1.
To 5-n. With this transmission, the location information of the mobile station 12 is registered in the control station 1 and the branch station county 5. [0004] In the conventional radio system, the mobile station operator does not always select the most appropriate branch station in terms of the line configuration, and sometimes selects the branch station incorrectly. is there. When the wrong branch station is selected, there is a disadvantage that the line connection cannot be performed quickly and reliably and a problem that good communication quality cannot be ensured as compared with a case where the optimum branch station is selected. Therefore, in the present invention, the mobile station always selects the most suitable branch station in terms of the line configuration, and the line connection can be quickly and reliably performed, and the excellent communication quality can be ensured. It is an object of the present invention to provide a good wireless system. According to the present invention, in order to attain the above-mentioned object, each branch station constantly transmits an empty signal as a line connection request with a mobile station and receives an empty signal. At the same time, the mobile station measures the input electric field strength of the empty signal, and the mobile station determines the optimal branch station in terms of the circuit configuration based on the measured input electric field strength.
One of them is connected to a line, and the location information of the mobile station is transmitted to the selected branch office. Then, the location information of the mobile station is transmitted to the control station, and further from the control station to all the branch stations, so that the location information is registered in the control station and all the branch stations in the communication area. An embodiment of the wireless system according to the present invention will be described with reference to FIGS.

The line control device 107 detects whether or not the terrestrial transmission / reception device 110 is communicating, and controls the communication operation of the terrestrial transmission / reception device 110. Under the control of the communication operation, the line control device 107 constantly transmits an empty line signal 115 which is a line connection request to the mobile station 112 via the terrestrial transmission / reception device 110. When the power of the mobile station 112 is turned on, each channel is scanned, and
05 (first branch office 105-1 to n-th branch office 105-n)
Are sequentially received via the terrestrial transmission / reception device 110. The mobile station 112 measures the input electric field strength of the received empty line signal 115, and selects an optimum branch station in terms of the line configuration according to the measurement result. Further, the mobile station 112 sends the location information 11 to the optimal branch station.
4 is transmitted. The position information 114 is transmitted to the control station 101 and the branch office county 105. By this transmission, the control station 1
01, the location information of the mobile station 112 is registered in the branch office district 105. For example, when the first branch office 105-1 is the most suitable branch office, the mobile station 112 is connected to the line controller 1 of the first branch office.
07 to the registration information (the location information 114 of the mobile station 112, the first
The ID number of the line control device 107 of the branch office is transmitted. Upon receiving the registration information 116, the line control device 107 of the first branch station transmits the response signal 117 to the terrestrial transmission / reception device 11
0 to the mobile station 112. In addition, the Control Bureau 10
The registration information 118 is transmitted to one centralized control device 102.
The central control device 102 is connected to the first branch office 105-1 to the n-th branch office.
Registration information 11 to the line control device 107 of the branch office 105-n
9 is transmitted. Central control device 102, line control device 10
7 transmits the registration information 120 to the control station relay switching device 103 and the branch office relay switching device 108, respectively. By transmitting the registration information, the control station 101, the branch office district 105
, The location information of the mobile station 112 is registered. Mobile station 112
Always scans each channel even after registration of the position information, and measures the input electric field strength of the empty signal 115 transmitted from the line control device of each of the branch stations 105-1 to 105-n. As a result of the measurement, the optimal branch office is the first branch office 105 selected earlier.
