Abstract

PURPOSE:To monitor quantitatively a service state, by monitoring a transmitted radio wave, collating the monitored signal with the signal transmitted immediately before monitoring and delivering the error information to a monitoring device when dissidence is obtained from the above-mentioned collation. CONSTITUTION:A monitoring receiver 6 monitors the radio wave which is actually transmitted from a transmitter 4 and then transmits the radio wave to a paging signal transmission controller 3. The controller 3 collates the data to which the transmission has just been indicated with monitoring data. If no coincidence is obtained from the collation, this result of collation is transmitted to a monitoring device 7. Then the device 7 counts the number of errors and performs a level analysis for the grave faults, the ordinary faults, the attention needed, etc. to deliver an alarm. At the same time, the device 7 prints out the fault level, the fault data and the time and data when the fault is generated through a printer 8. Thus it is possible to monitor quantitatively the service state without requiring an artificial test.

Description

[Detailed description of the invention] The present invention relates to a paging signal transmission monitoring system.

Conventionally, in paging services, the transmitter simply transmits the address code of the called pager (pager) from the call requester, so it is difficult to ensure that the address code is correct and appropriate. It was necessary to wait for complaints in the event of a defect or periodic maintenance tests to determine whether or not the transmission characteristics were met.

Furthermore, it is difficult to qualitatively grasp the actual service in unidirectional signal transmission called 4-baging.

FIG. 1 shows a system diagram of a conventional paging service system, where 1 is a call reception exchange, 2 is a paging transmitter group control device, 3 is a paging signal transmission control device, 4 is a transmitter, and 5
is a pager.

The pager call reception exchange 1 operates at a predetermined cycle (
For example, every minute), the paging calls that have been accepted up to that point are sent to the paging transmitter group control device 2 as data #! Communicate using. , l* The paging transmitter group control device 2 analyzes the paging call data sent from the pager call reception exchange 1 and determines which transmitter (single or plural)
a paging signal transmission control device 3 (single or plural) K that determines whether to transmit a paging signal and controls the corresponding transmitter;
Transfer paging call data. Immediately upon receiving a series of paging call data, the paging signal transmission control device 3 instructs the transmitter 4 to raise the transmitter output, and then causes the transmitter 4 to transmit the paging call data. Pager (t
If the transmitted call data includes data that matches a preset paging number, the paging number (or pager) 9 emits a ring tone to notify the owner.

In this paging service system, the paging call reception switch 1 accepts nine paging calls.In order to check whether the paging call request is being sent correctly to the transmitter 4, the maintenance personnel sends a large number of actual busy test calls. It was necessary to make a decision.

The present invention eliminates these drawbacks of the conventional ones, actually monitors the transmitted radio waves, compares the monitored transmitted data with the data sent just before, and when a discrepancy occurs, the error information is transmitted to the monitoring device. The paging signal is monitored qualitatively by outputting the signal to the paging signal.

According to the present invention, the present invention includes means for monitoring wireless output and transmitting the monitored contents to the paging transmission control device, and means for comparing the monitored contents with previously transmitted data and transmitting error information to the monitoring device if there is an error as a result. A paging signal transmission monitoring system is obtained, which is characterized in that it includes a paging transmission control device that receives the error information and monitors the error information from time to time.

Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, an embodiment of the present invention includes, in addition to conventional components, a monitoring receiver 5, a monitoring device 7. It is composed of a printer 8.

Here, the monitor receiver 6 monitors the radio waves actually transmitted from the transmitter 4 and transmits them to the paging signal transmission control device 3. The control device 3 compares the data that has just been instructed to be transmitted with this monitor data. The control device 3 notifies the monitoring device 7 if there is a discrepancy as a result of the comparison. The monitoring device 7 measures the amount of error and determines whether it is a major fault/normal fault/l.
! Analyzes the level of caution, etc. and issues a warning. At the same time, the monitoring device 7 causes the printer 8 to print out the fault level, fault data, and date and time of occurrence.

FIG. 3 shows the paging signal transmission control device 3 in FIG.
0 is a functional block diagram. In the figure, 21 is a data buffer that temporarily stores data sent from the paging transmitter group control device 2 shown in FIG. 2 onto the data communication path 24. Reference numeral 22 denotes a transmission control device, which instructs the transmitter to output when there is human power in the data buffer 21, extracts paging call signals that are sequentially input to the data buffer 21, and outputs them to the transmitter. Reference numeral 23 is a collation circuit that sequentially collates the monitor data sent to the information path 27 from the monitor receiver 6 shown in FIG. For example, it is output to the information path 25 connected to the monitoring device 7 shown in FIG.

With such a device, it is possible to constantly monitor the transmission signal of the paging service, so that interference waves and the presence or absence of their periodicity can be monitored at the same time.In addition, by tightening the reception characteristics of the monitor receiver, deterioration of the transmitter can be prevented at an early stage. It is also possible to discover.

As explained above, the present invention can qualitatively monitor the service status without requiring any human testing by comparing the one-page signal with the results of monitoring the actual output radio waves.
