Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention uses a standby processor to process a predetermined process while the active processor is executing the process. This invention relates to a method that enables accurate measurement of processing time.

(2) Prior Art and Problems Conventionally, various considerations have been made to measure the information processing time in electronic exchanges. Simply record the addresses of all the instructions executed by the processor when there is no load (when there are no calls), and the addresses of all the instructions executed by the processor from the start to the end of a certain call. The calculation for determining the difference between them is performed using an off-line program by a processor other than the processor operating in the exchange, and the processing is extremely complicated.

(3) Purpose of the Invention The purpose of the present invention is to improve the above-mentioned drawbacks, and to improve the measurement target information of processing of a processor that can operate in a dual system without using a special measuring device, by using a backup system. The objective is to provide a method that allows easy and accurate measurement.

(4) Structure of the invention The structure of the present invention to achieve the above object is as follows:
In a processor processing time measurement method for a redundant configuration information processing system that is equipped with two sets of processors and memories, and each processor has the function of reading the contents of the registers of other processors, the active processor has a program that processes the information to be measured. of,
A time measurement program is stored in the standby processor, and when a transition factor is detected during the execution of a periodic startup program among the programs that process time measurement target information in the active processor, the measurement start point of the time measurement target information is detected. It is determined that
At the same time as sending the start mate instruction to the standby processor, the periodic activation program sets the measurement target information flag in the transaction for starting the transition process, and sends the stop mate instruction to the standby processor, while the base level control program If the flag is set when a task is executed, by sending a startmate instruction to the standby processor and executing the task, the standby processor counts up the contents of the register between the startmate and stopmate instructions. By doing so, the processing time can be measured.

(5) Embodiments of the Invention Below, as an embodiment of the present invention, a case will be described in which the measurement target information is the processing time for calls called the call proportion of the electronic exchange. Call processing in a telephone exchange is formed by several states from call origination to call termination and transition processing between them, and processing related to the number of calls can be carried out by detecting transition factors by a periodic processing program or by detecting transition factors in proportion to the number of calls. Focusing on the fact that the processor is activated only by one of the transition processes (tasks) of This is the main point of the present invention.

FIG. 1 shows a system configuration of a first embodiment of the present invention. In Figure 1, when the subscriber telephone SUB makes a call and dials, the redundant processor
The CC and memory MM control the exchange network NW to send signals to the called party via the trunk TRK. One set of processor CC and memory MM is the active system ACT, and the other set is the standby system.
Becomes SBY. In the present invention, as will be described later, the register of the standby system SBY whose setting value changes depending on the call processing time is counted up, and after the predetermined processing is completed, the register value reading device RW connected between both processors is counted up. On the other hand, when the active ACT processor issues a read instruction, the contents of the register of the standby SBY are read. Incidentally, the inter-processor connection line P indicates a signal transmission line for mutually controlling the activation/stopping of the other system. The operation of FIG. 1 will be explained with reference to FIG. 2, which shows the processor memory and program extracted. In FIG. 2, a call processing time measurement program is initially loaded into the hatched portion of the set of memories MM (the one on the right side of the diagram) that will become the backup system SBY. In addition, the current system
Although not shown in the figure, it is assumed that the entire call processing program is loaded in the memory of the ACT group (MM on the left side of the figure). and subscriber telephone
When a call is made from SUB, processing begins in the active ACT,
At the start of the process, a "start mate (STM) command" is issued to the standby SBY processor.
The standby processor CC executes the call processing time measuring program, sets the initial value "zero" to the register Ri, and then counts up the contents of the register Ri by one. The next step in the backup SBY time measurement program is a jump command.
Since the execution returns to the previous position, that is, the point where the register is counted up, the register Ri is counted up by one more. This operation causes the current ACT to send a "stop mate (SOM)" signal that indicates the end of processing.
This will continue until the command arrives. If the time measurement program counts up the contents of register Ri by 1, executes the next jump instruction, and calculates the product of the time required to return to the point at which the count was increased and the count value of the spare SBY register. , the call processing time is calculated, and the "value proportional to the number of calls" is calculated.
is obtained. Next, the case where the active ACT processor sends the start mate STM command and stop mate SOM command will be explained with reference to the call processing program control diagram in FIG. In FIG. 3, the left side is a periodic activation program, and the right side is a base level control program. For example, the periodic startup program is
The subscriber's off-hook is monitored every 200 milliseconds, and when an off-hook event is detected, the program branches to the right in the control diagram. Since off-hook is subject to time measurement proportional to the number of calls, the program determines this and sends a start mate STM command to the standby SBY processor. At the same time (indicated by a black square frame), the program sets a flag in its own in-memory transition processing driving transaction as a call number proportional display. This transaction is connected to a so-called queue (QUE). When the above transition processing (task) is ready to start, the periodic startup program stops.
Sends the SOM instruction to the standby SBY processor (indicated by a white square frame) and stops the count up of the SBY registers. The periodic activation program then monitors calls made by others.

FIG. 4 shows the operation time chart of each system and the contents of the registers. The above explanation shows the operation at time _t1 and the contents of register Ri at time _t1 . Next, in the active ACT processor, the base level control program starts operating in order to start the task of preparing to receive a dial from the subscriber. Before this program starts a predetermined task operation, it always checks whether the call number proportional display flag is set on the transaction queue, as shown on the right side of FIG. When standing, the start mate STM command is sent to the preliminary system SBY before executing the base level task operation.
Send to processor (black square frame), register Ri
restart the count up. After executing a given task, the register Ri is set using the stopmate SOM instruction.
The count up will stop (white square frame). As shown in FIG. 4, for example, when time _t2 corresponds to this, the active system processor operates to receive the dial, and the standby system register Ri takes the value ( _t1 + _t2 ). If the aforementioned flag is not set when a task is executed, the standby SBY register will not be counted up. When dial reception is finished, the value is decoded, and processing such as relay transmission continues, start mate commands and stop mate commands are similarly sent. FIG. 4 shows that time has passed until t ₄ and the register value has increased.

In this way, the total call processing time until the caller goes on-hook is intermittently accumulated in the register of the standby system SBY, so the active system ACT processor stores the contents of the appropriate register after the call ends in the device RW of FIG. You can read it using .

If another task is started while the above-mentioned base-level control program is executing the task, the transaction is also flagged. Also, during task execution, when an "interrupt" occurs in processing by a periodically activated program, the active ACT processor
Sends a stopmate SOM command to the standby SBY processor unconditionally. Then, the interrupt control program checks the operating status of the standby SBY processor, and if it is in the "running state", the active processor ACT
A call count proportion display flag is set for the suspended task transaction in the processor. When the interrupted task is restarted after interrupt processing is finished, the flag is checked before restarting, so a startmate STM command can be sent.

FIG. 5 shows a second embodiment of the present invention in which one call is processed by a plurality of processors. In FIG. 5, CPR indicates a call processing processor (dual configuration), and MPR indicates a main processor (dual configuration). As explained in the first embodiment, after detecting the caller's off-hook and operating the active ACT processor on the left side of FIG.
When the processing extends to the group on the right, the original processor CPR measures its own call number proportionality using the backup processor of its own group, and at the same time sends communication data to the target call processing processor via the main processor MPR. Send. At that time, the communication data is sent with a flag indicating that it is proportional to the number of calls. On the other hand, since the call processing processor that is to receive the data monitors the arrival of communication data using a periodic activation program, it starts processing immediately after the data arrives. Then, by checking the flag regarding call number proportional display, measurement of the processor set in question is started. As a result, the proportion of calls can be measured separately in accordance with the processing operations of the processor.

The above explanation was about measuring the proportion of calls in an electronic exchange, but in addition to basic calls, it is also possible to measure the processing time of new service calls, billing processing, etc. It can be applied when you want measured values for each measurement target in relation to general data.

(6) Effects of the Invention In this way, according to the present invention, a special measuring device is provided by specifying the target information whose time should be measured regarding the processing operation of the active processor and having the standby processor execute this information. without doing,
It is possible to perform easy and accurate measurements.
