Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a terminal line input/output control method for setting the number of dedicated input lines and shared output lines according to the situation in a store-and-forward type communication device. It is related to.

(Prior Art) Recently, the demand for facsimiles has increased, and along with this, a wide variety of requests have arisen for services, and it has become impossible to meet these demands using the conventional method of using facsimiles. Therefore, store-and-forward devices such as facsimile mail devices were developed. Store-and-forward devices, typified by this type of mail device, do not communicate in real time; rather, the device stores the input communication message, performs the necessary processing, and then outputs it to the other party. The range of services has also expanded. However, when a large number of broadcasts occur, the terminal line is used for output, and even if an input call occurs, it becomes busy, resulting in a high call loss rate and making it difficult to use. Similarly, when multiple people input dozens of pages at the same time, the terminal line is taken over for input, making it impossible to output and increasing delay time. For this reason, in the past, traffic was predicted and restrictions were placed on human-powered input/output sharing (hereinafter referred to as input/output regulation) rather than human operation. However, such an operation has the following problems.

(Problem to be solved by the invention) When input/output regulation is performed by human operation, control is performed by predicting from information such as past traffic conditions, etc.
The drawback is that it is unable to respond to traffic changes that change from moment to moment, and is unable to implement appropriate regulations that suit the moment. Therefore, if you try to control the traffic according to the traffic, the operator must constantly monitor the traffic, which requires manpower and increases labor costs. At the same time, it has to be controlled frequently, which increases the burden on the operator.

In addition, if you increase the number of terminal lines for a mail device without limiting it, the call loss rate and waiting time will be reduced, but it will require adding a package for the mail device or adding the mail device itself, so the equipment cost will be very high. The shortcoming of becoming is gone.

This invention was made in order to solve the above problem, and by using a call loss measurement line separate from the terminal line, it is possible to perform appropriate measurement without increasing the number of terminal lines and without increasing the burden on human resources. The purpose is to provide a terminal line input/output control method that can be regulated.

(Means for Solving the Problems) A terminal line input/output control method according to the present invention includes: a voice response unit connected to a call loss measurement line separate from the terminal output; a line status measurement unit that measures a call loss rate; A recording section for recording the results, a measurement control processing section for estimating the call loss rate, and a communication section for sending the estimated call loss rate to the mail device main $IJ control section are added to the mail control main control section.

[Effect]

In this invention, (1) A representative number is set for the call loss measurement line of the device for measuring call loss together with the terminal line of the mail device. When the terminal line of the mail device is full and the mail device is accessed, the call is connected to a device for measuring call loss, and the call is assumed to be lost to the mail device, and the call loss rate is estimated.

■ Check the delay time from all messages (mails) stored in the storage device whose scheduled output time has passed;
Calculate a value (delay coefficient) that quantifies the delay status by taking into consideration the priority of the message (email), etc.

■ Input from past calculated call loss rates and delay status quantification values (delay coefficients), history of regulatory status, etc., the latest call loss rate and delay time quantification values (delay coefficients), and current terminal line usage status. Schedule and regulate output regulation.

Furthermore, the FCU 14 includes a voice response unit 15 that responds by voice to requests from the terminal, a transmitting/receiving unit 16 that receives messages (emails) from the terminal and sends them to the terminal, and controls input and output messages (emails). It consists of an input/output control section 17 that controls input/output limitations of terminal lines. The call loss measurement device 20 also includes a measurement system control processing unit 21 that processes the time history of calls that have occurred and determines the call loss status, and a line that measures the time history of calls that have been received from the terminal line to a voice response unit 24 that will be described later. A situation measuring unit 22, a recording unit 23 for recording the time history of calls, and a voice response unit 2 that notifies the access from the terminal by voice that the service is unavailable.

indicates a facsimile machine, and 70 indicates a telephone.

Next, the operation of input/output control of the terminal line 30 will be explained.

■ Assemble one terminal line 30 and m tree call loss measurement lines 40 with the same representative number (when using a PBX, only those that can be associated with a representative number).

■ When a call is made to the facsimile mail device 10 in a situation where there are no idle lines for input on the terminal line 30 of n trees, the terminal line 3o and the call loss measurement line 40 have a representative number, so the call loss measurement is performed. It is connected to the call loss measurement line 40 of the device 20.

■ Calls connected to the call loss measurement line 4o are sent to the voice response unit 2.
4, the user is informed that the line is congested and access to the facsimile mail device 10 is not possible. At the same time, the line status measurement unit 22 measures this as a lost call to the facsimile mail device 10 and records the time layer in the recording unit 23.

(2) Estimating the call loss status of the facsimile mail device 10 as a call loss rate from the time history of calls on the m call loss measurement lines 40 stored in the recording unit 23. In order to feed back the call loss rate determined here to the facsimile mail device 10, it is sent from the communication unit 25 of the call loss measurement device 20 to the facsimile mail device 10.

■ The file control unit 12 is an HD (hard disk) 1
Examine the messages (mails) accumulated in 3 and check the output message (
The delay status of mail) is quantified (delay coefficient) and fed back to the mail device main control unit 11.

■ The mail device main control unit 11 receives the call loss rate obtained from the call loss measurement device 2o through the communication unit 18 of the facsimile mail device 10 and the value (delay coefficient) that quantifies the delay status of ■.
Based on the current line restriction status obtained from the input/output control unit 17 of each FUC 14, the input/output restriction ratio of the terminal line 30 is determined according to the current traffic, and one terminal line 30 is scheduled. The results are sent to the input/output control unit 17 of each FUC 14 only when there is a change in the schedule of the line 30.

■ When the input/output control unit 17 of each FUC 14 receives input/output regulation information, the terminal line 30 executes input/output regulation based on the information held by the input/output control unit 17 as soon as the current service ends. .

■ Thereafter, the same operation is used to periodically control the human power/output regulation of the terminal line 30 using the call loss rate value from the call loss measurement device 20 and the quantified value of the delay status (delay coefficient) from the file control unit 12. .

〔Effect of the invention〕

As explained above, the present invention includes a voice response unit connected to a call loss measurement line, a line status measurement unit that measures the call loss rate, a recording unit that records the results, and a measurement control processing unit that estimates the call loss rate. A communication unit that sends the estimated call loss rate to the mail device main control unit is added to the mail device main control unit, and a schedule for regulating input/output of terminal lines is created based on the call loss rate and the delay status of messages stored in the storage device. By doing this, we have the following effects.

■Compared to humans regulating the input and output of terminal lines while observing the traffic situation, it is possible to make appropriate regulations according to the traffic situation.

■ Input/output regulation control is performed automatically, so there is no need for specialized personnel to operate it, resulting in savings in labor costs.

■ To make effective use of the terminal line of the mail device, input and
Unnecessary capital investment can be prevented by regulating output. (Call loss measurement equipment is inexpensive compared to the capital investment required to increase the number of terminal lines for mail equipment.) Also, when attempting to increase the number of terminal lines, check the history of the calculated parameters. This makes it possible to set an appropriate number of lines and prevent unnecessary capital investment.
