Abstract

PROBLEM TO BE SOLVED: To improve maintainability, and to improve the service performance, such as the quickness of countermeasure for an end user by investigating the occurrence or continuity of any defect, such as soft bug, firm bug, or signal missing which is not detected as failure before the claim from the end user. SOLUTION: Base stations 200 and 201 receive a number of complete calls as a response to a traffic collection request. The number of complete calls collected by each base station(BTS) 300, 301, 400 and 401 is held and managed for a prescribed time, for example one hour, and compared with a prescribed value after the lapse of one hour. When the collected number of complete calls is the prescribed value or less, it is deemed that some failure is caused in the base station, and the base station information such as the number of complete calls and the number of the base station are imparted to a maintenance device 500, whereas when the collected number of complete calls is more than the prescribed value, any information is not imparted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio base station maintenance system, and more particularly, to a radio base station maintenance system that can detect a failure occurring in a radio base station before a complaint comes from an end user.

[0002]

2. Description of the Related Art Conventional traffic management includes detecting abnormal traffic, narrowing down traffic of a communication service causing an abnormality, and adding, changing, and repairing hardware and software. Etc. are included.

[0003] As shown in FIG.
In the official gazette (“Traffic management method of intelligent network”), a table of connection result, start time and hold time is created for each call type and service control procedure, and the table is stored in the operation information storage unit 6a. Traffic is managed by calculating the number of incomplete calls and average hold time.

[0004]

However, conventional traffic management alone cannot quickly respond to end-user complaints. In other words, if a failure that cannot be normally grasped by the person who maintains the wireless base station, for example, a soft bug, a firmware bug, or a signal drop occurs and continues, if there is a complaint from the end user, the investigation will be carried out only after the end user complains. Will start.

[0005] In view of the above, according to the present invention, when a defect such as a soft bug, a firmware bug, and a signal drop which is not detected as a failure occurs and continues, it is investigated before a complaint is sent from an end user to improve maintainability. It is an object to improve serviceability such as quick response to end users.

[0006]

According to the present invention, there is provided a base station controller for controlling two or more base stations, and a mobile switching center for managing the two or more base stations. A maintenance apparatus for maintaining all of the base control apparatus, wherein the base station control apparatus collects the number of completed calls for each base station at a predetermined cycle, and performs another predetermined cycle. The total number of the completed calls for each base station is counted, and if the total number is equal to or less than a predetermined number, the total number is reported to the maintenance device.

That is, according to the present invention, in a mobile communication system composed of a mobile switching center, a base station controller, a base station, and a device for maintaining and operating the base station controller, a completion notification periodically transmitted from the base station is provided. The value of the number of calls is monitored, and if the number of calls is reported below the specified number, it is determined that some operation failure has occurred in the base station, the maintenance person is notified, and an investigation is prompted. The specified value can be set in units of time, and monitoring and judgment is performed using a specified value corresponding to the time. The information notified from the base station is determined based on information notified as traffic data.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a radio base station maintenance system according to the present invention. As shown in FIG. 1, the radio base station maintenance system according to the present invention includes a mobile switching center (MSC) 10.
0, base station controllers (BSC) 200, 201 and base stations (BTS) 300, 301, 4 under the control of the base station controller.
00 and 401 and a maintenance device 500 that performs maintenance operation of the base station control device.

[0010] The base station controller detects a failure of the base station and notifies the maintenance device 500. Then, the maintenance device 500
Shall take countermeasures for failure based on the notification.

FIG. 2 is a sequence diagram for explaining the operation of the radio base station maintenance system according to the present invention. As shown in FIG. 2, the base station-free control device 200
Request a report of the number of completed calls to 01 at regular intervals. Similarly, base station-free control device 201 transmits base stations 400 and 401
Request a report of the number of completed calls at a fixed period.

This fixed period is common to the base stations 200 and 201 and has a predetermined value, for example, considering the average traffic in the areas A, B, C and D under the control of the mobile switching center (MSC) 100. 5 minutes, etc. If the traffic volume is small, the predetermined value as the fixed cycle may be long. Also, a fixed value may be set for each call type and service control procedure.

The base stations 200 and 201 receive the number of completed calls as a response to the traffic collection request.

The base station controllers 200 and 201 hold and manage the number of completed calls collected for each of the base stations (BTS) 300, 301, 400 and 401 for a predetermined time, for example, one hour, and define the number after one hour has passed. Compare with value.

The predetermined time is determined by the base control stations 200 and 20.
1, which is set with reference to failure statistics and the like, but may be changed as needed according to the situation. Also, it may be set for each call type and service control procedure.

When the number of completed calls collected is equal to or less than the specified value, it is determined that a failure has occurred in the base station, and
The maintenance apparatus 500 is notified of the number of completed calls and base station information such as a base station number. This notification is made every predetermined time.

On the other hand, if the number of completed calls is equal to or greater than the specified value, no notification is made.

Based on the above-mentioned notification, maintenance, inspection, and repair of the base station are performed.

[0019]

According to the present invention described above, if a defect such as a soft bug, a firmware bug, or a signal drop which is not detected as a failure occurs and continues, it is possible to investigate before a complaint is filed by an end user. Since it becomes possible, serviceability such as improvement of maintainability and quick response to end users is improved. The reason is that by automatically monitoring the number of completed calls, it is possible to find a defect that prevents the call from being accepted.
