DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for automatically detecting many failures according to an embodiment of the present invention will be described with reference to FIG. FIG.
FIG. 2 is a block diagram of a mobile communication system according to the embodiment. In FIG. 1, reference numeral 100 denotes a mobile switching center for controlling a switching connection, and reference numerals 200 and 201 denote base station controllers for controlling the base stations 300, 301, 400 and 401. Base stations 300 and 301, 400 and 40
1 communicates with a mobile terminal (not shown) under the control of the base station controllers 200 and 201. Reference numeral 500 denotes a maintenance device that performs maintenance operation of the base station control devices 200 and 201.

Next, the operation of the embodiment of the present invention will be described with reference to FIGS. The base station control device 200 of FIG.
Reference numeral 201 includes a traffic monitoring unit, a traffic collection unit, a traffic data storage unit, a continuous count unit, and the like. FIG. 2 is a sequence diagram showing an operation of the mobile communication system of FIG. Base station controller 20
The traffic monitoring units 0 and 201 make traffic data collection requests to the traffic collection unit at regular intervals, for example, every five minutes. Each traffic collection means
In response to the traffic data collection request, the collected traffic data is returned to the traffic monitoring means.

[0011] The traffic monitoring means of the base station controllers 200, 201 examines the radio resource acquisition failure, resource busy, call connection failure factor, and handoff failure factor in the traffic data returned from the traffic collection means. Then, for example, the base station control device 200
If the traffic monitoring unit of the base station controller 200 detects that only the value of the radio resource capture failure exceeds the specified value, the traffic monitoring unit of the base station control device 200 determines that the value of the radio resource capture failure is While being stored in the data storage means, the corresponding continuous number counting means is incremented by one. Also, the base station controller 20
The traffic monitoring means of 0 clears the contents of the traffic data storage means and the continuous number counting means corresponding to the traffic data other than the radio resource capture failure. on the other hand,
The traffic monitoring unit of the base station control device 201, for example, when the values of the radio resource acquisition failure, the resource busy, the call connection failure factor, and the handoff failure factor are all below the specified values, the content of the traffic data storage unit And all the contents of the continuous counting means are cleared.

In the next cycle, the base station controllers 200 and 20
The first traffic monitoring unit issues a traffic data collection request to the traffic collection unit in the same manner as described above, and fails to capture a radio resource in the traffic data returned from the traffic collection unit.
Examine the cause of the call connection failure and the cause of the handoff failure. Then, for example, when the traffic monitoring unit of the base station control device 200 detects that the radio resource acquisition failure and the value of the resource busy exceed the specified value, the traffic monitoring unit of the base station control device 200 The values of the radio resource acquisition failure and the resource busy are added to the contents of the corresponding traffic data storage means, and the corresponding continuous number counting means is incremented by one. Further, the traffic monitoring unit of the base station control device 200 clears the contents of the traffic data storage unit and the continuous count unit corresponding to the traffic data other than the radio resource capture failure and the resource busy. On the other hand, when the values of the radio resource acquisition failure, the resource busy, the call connection failure factor, and the handoff failure factor are below the specified values, the traffic monitoring unit of the base station control device 201 And clear the contents of the continuous counting means.

Similarly, base station controllers 200 and 20
The traffic monitoring means collects traffic data from the traffic collecting means at regular intervals, and determines whether the value of the traffic data exceeds a specified value and the content of the corresponding traffic data storage means and the continuous count. Add or clear the contents of the means. Then, for example, when the content of the continuous number counting means corresponding to the radio resource acquisition failure of the base station control device 200 has reached the specified number, that is, the state in which the value of the radio resource acquisition failure exceeds the specified value continues for the specified number of times. If the problem occurs, the traffic monitoring means of the base station control device 200 notifies the maintenance device 500 of the occurrence of the problem.

Thus, the maintenance person can identify the trouble occurrence in the mobile communication system and analyze the traffic data stored in the traffic data storage means of the base station controller 200 to solve the problem at an early stage. Will be possible.

The traffic data collection cycle in the traffic monitoring means of the base station controllers 200 and 201, the specified value for judging the collected traffic data, and the specified number of times for judging whether the collected traffic data exceed the continuous specified value are determined in advance. The base station controllers 200 and 201 may be incorporated in the respective traffic monitoring means or may be commanded from input means (not shown) of the maintenance device 500.
Can be set in the traffic monitoring means.

[0016]

As described above, according to the present invention, the base station controller collects traffic data at regular intervals, and collects traffic data when the value of the collected traffic data exceeds a specified value. The traffic data is added to the contents of the traffic data storage means, and when the number of times exceeding the specified value has continued for the specified number of times, the occurrence of a problem is notified to the maintenance device. At this time, the occurrence of many failures can be automatically detected. As a result, maintenance personnel can discover problems at an early stage, and by analyzing problems based on the collected traffic data, it is possible to solve problems early and improve service to end users. Become.
