Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for collecting management data of a plurality of communication devices in a transmission communication system and the device.

[0002]

2. Description of the Related Art In a transmission communication system, a management device is provided as a monitoring system in order to centrally monitor a plurality of remote communication devices, and each of the plurality of communication devices communicates through a communication line by polling. The management data is divided and collected for each predetermined unit transmission data amount.

Conventionally, when management data is collected through the same communication line as that of a general user, the communication line is temporarily occupied for management data collection, and there is a possibility that communication of failure detection and user communication may be adversely affected. there were. Therefore, various methods have been proposed for reducing the line occupation time for collecting the management data. For example, JP-A-6-16452
In the proposal disclosed in Japanese Patent Publication No. 3 "Transmission device centralized monitoring system", the middle layer monitoring system collects management data from each communication device only when a control command is sent from the highest monitoring device, and collects the collected management data. The management data is sent to the uppermost monitoring device in a similar manner and the status table held therein is updated, thereby shortening the occupation time of the communication line.

[0004]

However, in the conventional management data collection systems described above, the unit transmission data amount of the management data division collected from each communication device is set to a constant value common to all communication devices. However, the allowable data amount of the communication line between the management device and each communication device has not been considered.

Therefore, if this unit transmission data amount is set to a large value, communication other than user data and management data is squeezed at the peak of management data transmission on a line with a small allowable data amount. There is a problem that the management data may be discarded, and conversely, if the unit transmission data amount is set to be small, the number of times of transmission and reception of the management data increases and the total time of the management data collection becomes longer.

An object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a management data collection method for a communication apparatus and a communication apparatus capable of adjusting the total required time for management data collection within an allowable range without hindering communication other than management data collection.

[0007]

According to the method of collecting management data of a communication device of the present invention, a unit transmission data amount per frame is individually set for each communication device, and the management device collects management data from each communication device. At the time of collection, management data is collected in units of the unit transmission data amount set for each communication device.

A management data collection device for a communication device according to the present invention comprises: a unit data transmission amount setting means for individually setting a unit transmission amount of management data collected from each communication device for each communication device; Collection function execution means for requesting data transmission, and transmission / reception control means for dividing and transmitting the management data according to the set individual unit data transmission amount when transmission of management data is requested from the collection function execution means. Have.

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

FIG. 1 is a system configuration diagram of an embodiment of the present invention. In FIG. 1, the system includes a plurality of communication devices 2 and 3 having terminals 4 and 5, respectively, and a management system for collecting management data from the communication devices 2 and 3 and the like via a time-division multiplex communication line 9. Management device 1
Is a collection function execution unit 6 for requesting each of the communication devices 2 and 3 to transmit and receive management data, a transmission and reception unit 7 for controlling transmission and reception of management data, and unit transmission data amounts d1 and d2 set for each communication device. Data amount table 8 in which data etc. are stored
And For simplicity of description, FIG. 1 shows one management device and two terminals and two communication devices, but the numbers are not limited thereto, and the number of communication devices and the number of hierarchies may be larger. There may be a management device.

Now, the unit transmission data amount per frame of the communication devices 2 and 3 is d1 and d2 per second, respectively, and the total amount of management data of the communication devices 2 and 3 to be collected by the management device 1 is D1 respectively. , D2, the transmission interval of the management data to each communication device is t, and the delay time required for transmission and reception between the management device 1 and each of the communication devices 2, 3 is T1, T2, respectively. The peak of transmission / reception is (d1 + d2) × 2.

The time T required to complete the transmission and reception of the management data with all the communication devices is MaxＭA,
B｝ is the larger value of A or B, INT (C
/ D) is an integer value obtained by dividing C by D and truncating the decimal part, T = Max {{INT (D1 / d1) +1} xT1x2xt, {INT (D2 / d2) +1} xT2x2
xt}.

That is, first, the total amount D1, D2 of the management data for each communication device is calculated by the unit transmission data amount d.
1 and d2 to determine the number of transmission frames for each of the communication devices 2 and 3, and then multiply each of these frames by the transmission / reception delay times T1 and T2 and the transmission interval t to obtain the number of frames for each communication device The required management data collection time is determined, and then the longest time among the required times for each of the communication devices is selected. This is the management data collection required time T for all the devices to be collected via the time division multiplex communication line. become.

Next, as a specific example, for example, the total management data amounts D1 = 10 and D2 = 10 of the communication devices 2 and 3, the respective delay times T1 = 1 and T2 = 2, and the respective transmission intervals t = 1
As a comparison between the conventional method and this embodiment, first,
In the case of d1 = d2 = 10, in which the unit transmission data amount common in the conventional method is relatively large, the peak per second is 40 data, the complete transmission and reception of management data is 4 seconds, and the unit transmission data amount is relatively small. When d1 = d2 = 1 is reduced, the peak per second is 4 data, the total management data transmission / reception completion time is 44 seconds, and when d1 = d2 = 5 when the unit transmission data amount is an intermediate value. The peak per second is 22 data, and the completion time of all management data transmission / reception is 12 seconds.

On the other hand, if the unit transmission data amount d1 of the communication device 2 is 4 and the unit transmission data amount d2 of the communication device 3 is 6 in the present embodiment, the peak per second is 20 data,
The total management data transmission / reception completion time is 8 seconds.

As described above, since the peak data amount and the total required time for management data collection can be set to intermediate values, the unit transmission data amount of management data collected from each communication device can be reduced for each communication line. By individually setting according to each traffic volume, it is possible to reduce the risk that user data will be squeezed for collection of management data on a line with a small amount of transmittable traffic and that management data will be discarded Can be.

[0017]

As described above, according to the present invention, the amount of traffic that can be transmitted is set by individually setting the unit transmission data amount of the management data collected from each communication device according to the traffic amount for each communication line. There is an effect that it is possible to suppress the danger of collection of management data squeezing user data or to discard management data on a line with a small size.
