Abstract

PURPOSE:To confirm the normal state of the entire system at general situation by applying test communication automatically between stations according to the predetermined rules and confirming the normal state of various equipments being components of the radio communication system based on the result of the test communication. CONSTITUTION:When the communication connection is implemented continuously and normally, each communication connection relates to the test communication and it may be discriminated that the radio communication system is operated normally thereby, a monitoring equipment 5 monitors the state of achieving the normal connection to maintain and monitor the overall radio communication system automatically. On the other hand, in order to maintain the monitoring quality in the case of the communication traffic remarkably decreased such as at night, a pseudo mobile station 4 is provided in addition to the monitor 5. The pseudo mobile station 4 applies automatic calling to ensure the minimum traffic and the calling aims for confirming the normal state of the system, then the procedure for the line connection is left to attain the object and the calling of a subscriber or the actual assignment of the radio channel is not required.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a method for maintaining and monitoring a wireless communication system.

[Prior Art] Conventionally, maintenance and monitoring of a wireless communication system has been performed by integrating individual abnormality detection devices for various devices provided in advance in the system.

For example, for a transmitter, comprehensively monitor the outputs of PR, R, circuit unlock detection circuit, output level reduction circuit, output abnormal reflection detection circuit, power supply voltage abnormality detection circuit, device temperature abnormality detection circuit, etc. This allows us to detect equipment abnormalities and perform system maintenance and monitoring.

[Problems to be Solved by the Invention] However, in the conventional maintenance and monitoring means for wireless communication systems as described above, when an abnormality is detected based on outputs from various circuits, it is difficult to determine that the wireless communication system is in an abnormal state. Although it can be immediately determined that
It cannot be determined that the wireless communication system is in a normal state. This is because hardware-based detection circuits for abnormality detection have limitations due to economic or technical constraints.

This invention was made to solve the above-mentioned problems, and instead of detecting hardware abnormalities in individual parts of the system, the system as a whole can be monitored to ensure normal system operation. The purpose of this invention is to obtain a maintenance and monitoring method for a wireless communication system that finally allows easy confirmation of the situation.

[Means for Solving the Problems] A method for maintenance and monitoring of a wireless communication system according to the present invention automatically performs test communication between stations according to a predetermined rule, and performs wireless communication based on the result of the test communication. This is to confirm the normal operation of the various devices that make up the system.

[Function] In the method for maintenance and monitoring of a wireless communication system according to the present invention, test communication is performed using the same procedure as the communication procedure actually performed, so that the normal state of operation of related system components can be checked over as wide a range as possible. You can check it with. Instead of testing how many pieces of hardware as in the past, test communication is performed to check whether actual communication can be performed normally, so it is possible to confirm the overall normal state of the entire system.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1st
FIG. 1 is a block diagram showing an apparatus for carrying out a method for maintaining and monitoring a wireless communication system according to an embodiment of the present invention. In this embodiment, a car telephone system is used as a wireless communication system.

In FIG. 1, 1 is a radio channel device, 2 is a car telephone exchange, 3 is a mobile station (automobile), 4 is a pseudo mobile station for the purpose of test communication regarding the present invention (described later), 5
is a monitoring device that can comprehensively determine whether or not this wireless communication system is operating normally.

Normal communication operations in the system as described above are performed as follows. That is, a telephone call is made between the general subscriber telephone terminal and the mobile station 3, which are connected via the car telephone exchange 2, after the line connection control communication. Among line connection control communications, for example, call control is generally when the mobile station 3 receives and analyzes connection control parameters broadcast from the radio channel device 1, and then sends a connection request when determining that it is possible to make a call. is activated by Upon receiving the connection request, the radio channel device 1 analyzes the connection request parameters and determines that connection is possible, transmits the connection destination information to the car telephone exchange 2, and calls the calling subscriber's telephone terminal. On the other hand, a radio channel used for telephone calls is assigned to the mobile station 3 to enable telephone calls.

If such call connections are made continuously and normally, each call connection is considered to be a test communication, and from this it can be determined that the wireless communication system is operating normally. By monitoring the execution status of this normal connection operation, the monitoring device 5 can automatically perform overall maintenance and monitoring of the wireless communication system.

On the other hand, when call traffic drops significantly, such as at night, the normal connection operation interval becomes longer, making it impossible to obtain a sufficient monitoring function. In this embodiment, in order to maintain monitoring quality in such a case.

A pseudo mobile station 4 is attached to the monitoring device 5. This pseudo mobile station 4 is used to automatically make calls and ensure minimum traffic.The purpose of making calls is to confirm the normal status of the system, so the procedure for connecting one line achieves that purpose. To the extent possible, it is not necessary to call subscribers or actually allocate radio channels.

In this way, according to the method of this embodiment, test communication is performed using the same procedure as the communication procedure that is actually performed, so unlike conventional tests that target individual hardware, the entire system is tested. The overall normal state of the system can be easily and reliably confirmed, and it is also possible to easily confirm abnormalities in the antenna, CPU, etc. that are difficult to detect with hardware detection circuits.

In the above embodiment, automatic test communication is performed based on the rule of ensuring minimum traffic in order to effectively utilize the wireless channel.However, in a simple system, regular communication can be automatically performed without monitoring communication, regardless of traffic. Test communication may be performed using the same procedure as normal communication. In this case, since the objects to be monitored are limited, there is an advantage that the monitoring algorithm of the monitoring device 5 is simple.

[Effects of the Invention] As described above, according to the present invention, various devices that automatically perform test communications between stations according to predetermined rules and configure a wireless communication system based on the results of the test communications. Since the normal operation of the system is confirmed, maintenance and monitoring of the entire system can be easily and reliably performed, rather than detecting hardware abnormalities for each type of equipment individually.
