Abstract

PURPOSE:To prevent a communication processor in advance from falling into an over loading state by incorporating a monitoring and controlling part, which executes operation control to one monitoring terminal for the communication condition of a terminal equipment, and a central monitoring and controlling part to execute an operation control instruction to each monitoring and controlling part. CONSTITUTION:Under a normal traffic state, the monitoring and controlling parts 2 repeat operation to measure a response time and to transmit measured results to a central control part 5. Next, when the delay of response is detected in the central control part 5, and an operation control signal is received, it is identified whether a signal is present or absent and whether the signal is a regulating signal or not, and a flow stop state is set. Afterwards, the reception of an incoming telegraphic message is identified and since the flow stop state is set, flow stop transmission is executed to the terminal. In such regulation processing, the traffic is regulated so that data can flow into the communication processor 1. As a whole, the central monitor and control part 5 detects the improvement of the response and transmits a flow stop cancel signal to the monitoring and controlling parts 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for processing specific traffic in a communication processing device, and in particular, to a method for processing specific traffic in a communication processing device, particularly for dealing with burst traffic that exceeds the capability of a multi-terminal communication processing device having a plurality of terminal control units. The present invention relates to a singular traffic processing method in a communication processing device that avoids an overload state of the communication processing device due to the occurrence of traffic (singular traffic).

[Conventional technology]

In the conventional specific traffic processing method in a communication processing device, as shown in FIG. 5, a communication processing device 51 includes a plurality of terminal control units 52 and a central processing unit 53. Further, each terminal control unit 52 and central processing unit 53 each has a function of independently detecting its own convergence state,
For example, when the central processing unit 53 detects its own congestion, it sends an operation stop signal (hereinafter referred to as flow stop) to all the terminal control units 52, and when the congestion is alleviated, it releases the flow stop to all terminal control units 52. The method is to control the operation by transmitting the information to the terminal control section 52, and when the terminal control section 52 detects its own congestion, to control the operation to the other terminal.

[Problem to be solved by the invention]

The above-mentioned method for handling singular traffic in conventional communication processing equipment is a method in which operation control is performed only after each terminal control unit and central processing unit independently detects their own congestion state. When messages come in in bursts, it is necessary to keep the congestion state detection processing function running at all times, which increases the processing power required, resulting in less processing than the traffic that could originally be processed. You can only demonstrate your abilities.

In addition, a process is required to perform operation control after detecting congestion, and there is a problem in that if congestion occurs suddenly due to specific traffic, the process itself that performs operation control becomes inoperable.

[Means to solve the problem]

A specific traffic processing method in a communication processing device according to the present invention includes communication processing performed by a plurality of terminal control units that accommodate terminals and control the terminals, and a central processing unit that communicates with the network side and the plurality of terminal control units. In the specific traffic processing method in a communication processing device that performs This configuration includes a central monitoring and control unit that receives the communication status and issues a communication traffic control instruction for regulating the traffic from the terminal before the entire communication processing device becomes overloaded.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

The communication processing device 1 includes a plurality of terminal control units 2 that connect to individual terminals, and a supervisory control unit that is provided in pairs with the terminal control unit 2 and monitors and controls the communication status including the time relationship until a response to a transmission from the terminal. The unit 3 connects with all the monitoring and control units 3 to receive the communication status of each terminal, and sends communication traffic control instructions to the monitoring and control unit 3 to regulate the amount of communication from the terminals before an overload condition occurs. The central processing unit 5 is equipped with a central monitoring control unit 4 that outputs information, and a central processing unit 5 that communicates with the network side and a plurality of terminal control units 2.

The monitoring control unit 3 includes a message transmission/reception control unit 12 that controls transmission and reception of messages exchanged between the terminal and the network, and a signal reception unit 13 that receives instructions from the communication amount control unit sent from the central monitoring control unit 4. and a timer 14 that is activated upon receiving the uplink message sent from the terminal, and a central supervisory control unit that reads the time from the timer 14 until the downlink message in response to the terminal is received from when the timer 14 is activated. 4, and a transmitter 15 for transmitting data to

FIG. 3 is a block diagram of the central supervisory control section 4 of FIG. 1.

The central supervisory control unit 4 monitors a buffer 24 that receives the timer value sent from the transmitting unit 15 of the supervisory control unit 3 and the received contents of the buffer 24, and if a delay in response is detected, outputs this to the control unit 22. A monitoring unit 23 is provided.

Next, the operation will be explained.

The operation of the supervisory control unit 3 shown in FIG. 2 will be explained with reference to the flowchart in FIG. 4, starting with the operation during normal traffic.

In step 31, it is determined whether or not an operation control signal from the central supervisory control unit is being received. In this case, since no operation control signal has been received, the process moves to step 34.

In step 34, it is determined whether the normal message is an upstream message from the terminal, and if it is an upstream message, the flow is not stopped in step 35, so the process moves to step 36. In step 36, a response message (
If there is, a timer is activated in step 37 to measure the response time. Thereafter, when a downlink message is received, it is identified in step 34, and after detection in step 40, the timer is stopped in step 41 and the timer value is transmitted to the central monitoring control unit 5 in step 42. In this way, during normal traffic, the monitoring control section 2 repeats the operation of measuring the response time and transmitting the result to the central control section 5.

Next, the central monitoring and control unit 5 detects a delay in response,
The operation when an operation control signal is received will be explained.

In step 31, the presence or absence of a signal is determined, in step 32 it is determined whether or not it is a regulation signal, and in step 33 a flow stop state is established. Thereafter, reception of an uplink message is identified in step 34, and since the flow stop state is detected in step 35, a flow stop transmission is performed to the terminal via step 3. In this regulation process, the message flowing into the communication processing device 1 is transmitted to the terminal via step 3. The traffic is regulated, and the central supervisory control section 5 detects an improvement in the response as a whole, and sends a flow stop release signal to the supervisory control section 2.

The operation when the monitoring control section 2 receives this flow stop release signal will be described below. First, in step 31, it is identified as a signal, in step 32, a flow stop release signal is identified, in step 38, the flow stop state is released, and in step 3, the normal traffic state is established.
Send flow stop cancellation to the terminal.

It is possible to prevent the communication processing device from becoming overloaded due to the occurrence of Since the process performs measurements and performs operational control without imposing any load on the control unit or central processing unit, there is a very low possibility that the communication processing unit will become overloaded, making it a reasonable regulation process from the user's perspective. This has the effect of
