TECHNICAL FIELD OF THE INVENTION
The present invention relates to a traffic measurement method, and more particularly to a traffic measurement method for automatically increasing or decreasing the number of lines subject to traffic measurement in accordance with the CPU utilization of an exchange.

[Prior art]
Generally, in an exchange, there is a need to collect detailed traffic data for each subscriber line in order to grasp a detailed service usage trend of the subscriber. However, the CPU incorporated in the exchange has a limited processing capacity, and a processing capacity distribution with priority given to call processing, which is the original function, is first set. The minimum required traffic measurement does not affect call processing. Only the ability distribution is set. Therefore, a method of collecting only a minimum necessary line traffic is usually adopted.
[0003]
However, the exchange has sufficient processing capacity during normal operation, and is limited to the minimum necessary line traffic collection even though it is capable of collecting detailed line traffic. I can't say.
[0004]
As one example of such a traffic measurement technique, a “traffic measuring device and a traffic measuring method” described in JP-A-10-304060 is known.

In this publication, the traffic measurement method in the traffic measurement unit 4 of the traffic measurement device 3 is automatically changed by the measurement method change control unit 6 for each call control in accordance with the load state of the call control in the exchange 1. One of the first measurement method for measuring and the second measurement method for measuring traffic at a predetermined cycle describes a technique of changing the load state according to the load state measured by the load state measurement unit 5.
[0006]
[Problems to be solved by the invention]
The conventional traffic measurement method described above has a drawback that the collection efficiency of traffic is not always good because the processing capacity distribution giving priority to call processing is emphasized and only the minimum required line traffic is collected for traffic measurement. Have.
[0007]
In addition, since the traffic measurement method is changed to either the first measurement method for automatically measuring each call control or the second measurement method for measuring traffic at a predetermined cycle, the traffic measurement method is consistent with the unit of the measured traffic data. It has the drawback that it is confused at the time of use due to lack of performance.
[0008]
An object of the present invention is to allocate the CPU processing capacity of an exchange to measure detailed traffic data for each subscriber during normal operation, and the call processing of the exchange is congested, resulting in a high processing capacity utilization rate.

[0027]
The communication processing units 71 to 76 measure the traffic and send the measured data to the traffic editing and collection control unit 80. The traffic edit collection control unit 80 edits the measured traffic data in a cycle such as 15 minutes or 1 hour, and makes a file as traffic data of the exchange 10.
[0028]
The system management unit 60 activates the traffic edit collection control unit 80 and the processing capacity monitoring unit 90, and stores “traffic collection priority information for each line” in the collection priority storage unit 81 and the collection regulation threshold storage unit 91.

A start request 66 is notified to resume traffic collection. If there is no communication processing unit 71 to 76 that has stopped collecting traffic, the traffic editing and collecting control unit 80 discards the release request 63.
[0032]
“Traffic collection priority information for each line” defined in the collection priority storage unit 81 and “Collection regulation processing capacity usage rate and usage rate threshold information” defined in the collection regulation threshold storage unit 91 Is set arbitrarily by the maintenance person via the system management unit 60 from the maintenance terminal 50 irrespective of the operation state of the exchange 10.
