Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for remote control of speech lines and control lines in a mobile communication network and for monitoring the status of speech lines, control lines, and equipment necessary for line setting.

FIG. 1 shows the configuration of a car telephone system as an example of a conventional mobile communication network. In the conventional car telephone system, a plurality of wireless base stations 1 each having a plurality of transmitters and receivers are arranged, and wireless zones 5 are overlapped to form a service area. The radio base station is connected to the radio network control station 2 through a communication line and a control line.
The radio line control station 2 is connected to a mobile telephone exchange 3 that connects the general telephone line network and the mobile telephone line. A speech line and a control line connected to the radio base station are connected to the mobile station 4 via radio.

In such mobile communication networks, line usage changes rapidly, such as switching to another wireless zone as a mobile station (car) advances, so it is difficult to manage and operate the line. The status of lines within an area can be centrally monitored, and operations such as capturing and blocking any line of each wireless base station can be performed centrally at a specific location in order to isolate when a failure occurs. is desirable.

However, conventionally, when it is necessary to block a communication line or control line for inspection, repair, etc., each wireless base station or wireless line control station closes the line for each device to which the line is connected. Performed manually,
Additionally, since the status of lines and equipment had to be checked on-site, there was a drawback that maintenance work was not quick enough.

In order to solve these drawbacks, the present invention enables blocking and unblocking of telephone lines and control lines by remote control, and also makes it possible to constantly monitor the status of all telephone lines, control lines, and devices necessary for line setting. This will be explained in detail below using the drawings.

FIG. 2 shows an embodiment of the present invention, in which 6 is a line control unit subject to blockage control, 7 is a manual blockage switch, 8 is a radio base station transmitting/receiving device, 9 is a supervisory control signal transmission processing unit, and 10 is a monitoring unit. 1 is a control line; 11 is a supervisory control processing unit; 12 is a supervisory control console; 13 is a radio base station controller; 14 is a telephone line and a control line;
5 is a radio line control device. In FIG. 2, when an arbitrary call line or control line 14 is to be blocked by remote control, the wireless base station and line are designated on the supervisory control console 12, a blocking command is stored in the supervisory control processing unit 11, and the It is attached with a line number and sent to the line control unit 6 via the supervisory control signal transmission processing section 9 of the radio base station. As a result, if a corresponding line control unit exists, the line control unit 6 executes the command and returns an execution confirmation signal to the supervisory control signal transmission processing section 9. This execution confirmation signal is sent to the monitoring control console 1 via the reverse route to the blockage command.
2 and displayed for confirmation on the monitoring control console 2. If blockage is not possible, that is, if the corresponding line control unit does not exist, a blockage impossible signal is sent from the line control unit to the supervisory control console 12 via the same route as the execution confirmation signal. When unblocking is performed, the same procedure as in the case of blocking is performed.

It should be noted that the present invention also enables manual closure, which has conventionally existed. When manually blocking an arbitrary line, the line control unit 6 closes the line using the manual blocking switch 7 and sends a manual blocking confirmation signal to the supervisory control processing section 11. The supervisory control processing section 11 stores this signal and displays it on the supervisory control console 12. When manually blocking a call line or a control line that has been blocked by remote control, the supervisory control processing unit 11 receives a manual blockage confirmation signal, and before the reception, it switches the stored information on the blockage state by remote control to the manual blockage state. , the display of the blockage state of the monitoring control console 12 is also changed to a manual blockage display. Manual unblocking is also carried out in the same procedure as manual blocking, but when manually unblocking a blocked line by remote control, operating the manual blocking switch 7 will not immediately unblock the line, and the manual unblocking signal will not be released immediately. is the supervisory control processing unit 1
1. In response to this, the supervisory control processing unit 11 displays a manual blockage release permission request on the supervisory control console 12, and when permission is obtained, sends back a manual blockage release permission signal. The corresponding line control unit 6 is unblocked upon receiving this signal.

As explained above, the blocking and unblocking of the communication lines and control lines of each station in the mobile communication network can be centrally performed at a specific location by remote control, and the status of the communication lines, control lines, and equipment necessary for line setting can be monitored. Since constant monitoring is possible, there is an advantage in that the efficiency of line maintenance and operation can be significantly improved.
