Abstract

PURPOSE:To reduce the line occupation rate of ineffective calls of a transmission line due to unnecessary calling by providing an exchange with a time measuring device which measures the elapsed time of the use of a busy communication terminal equipment and reporting the elapsed time of the use to the originating communication terminal equipment. CONSTITUTION:A use elapsed time measuring device 5 receives a driving signal and a release signal from a controller 4 together with terminal numbers given to communication terminal equipments 3 and measures the elapsed time of the use of each communication terminal equipment 3 by an independently received clock signal, and the measured elapsed time is outputted when a read request with a terminal number as the address comes. The time measuring device 5 is called when it is detected by the controller 4 that the communication terminal equipment 3 called by an incoming call is busy, and the terminal number of the called communication terminal equipment 3 is used as the address to take out the elapsed time. A busy information transmission equipment 6 receives busy information including the elapsed time of the use from the controller 4 and transmits this received busy information to the originating communication terminal equipment 3 connected through a main switch 1 by the controller 4.

Description

[Detailed Description of the Invention] [Field of Application for Consideration] The present invention relates to a main switch that connects all communication terminal devices via terminal lines, and a control system that mainly controls all the retrospective interconnections of the terminal lines. Concerning all types of exchange equipment.

[Conventional technology]

The conventional switching device IT has an information sending device that receives busy information indicating that a called 1G terminal device is in use from a control device and sends a busy signal to a friend, originator, and private terminal device. One in-use signal is, for example, a telephone call signal.
Furthermore, data terminals use digital codes.

[Problem that the invention seeks to solve]

As mentioned above, the conventional switching equipment can only send one busy signal when the called communication terminal is in use, so it is unknown how much time has passed since the called communication terminal started using the service, and how much time has elapsed since It is completely unclear whether it is appropriate to make eight calls. Therefore, in many cases, calls are made many times in a row in the hope of being immediately connected, and this often causes the problem that an increase in the line usage rate due to unnecessary occupation of the transmission line causes an increase in the busy rate.

The purpose of the present invention is to solve all of the above problems. Our goal is to provide an enviable device.

[Means to solve the problem]

The communication device fjt of the present invention includes a time measuring device that measures the elapsed time in use for each communication terminal device for one history A, and an information sending device that sends in-use information including the elapsed time in use to A. has.

t# message sending equipment is to send out all text information and/or synthesized voice information, and if the calling communication terminal has a character display function and text information is sent from the information sending device, The elapsed relay time is displayed in text on the Kano Tsushin Zuishi device.

[Embodiment 1] Next, the refueling device of the present invention will be explained with reference to the drawings.

FIG. 1 is a functional block diagram showing one embodiment of the present invention. The main switch 1 is connected to the communication terminal F32 and the traffic machine 7 via a terminal line 812 and a relay line 82 housed in the line Innotaface 2, respectively. The control device 4 knows all the line status from the line interface 2 and transmits 1M.
The main switch 1 is mainly controlled by receiving transmitted signals from the terminal g&li 3B and the intercom 7. Usage elapsed time measurement #c & (hereinafter referred to as time measurement device) 5 is control device 4
The drive signal and the release signal, which are information about the start and end of use of the communication terminal device 3 and the start and release information, are received together with the terminal number assigned to the communication terminal device 3, and the clock signal received separately is used. The elapsed time during use of each communication terminal device 3 is measured, and when a read request is rarely received as the terminal number and all addresses, the time is measured and the elapsed time is outputted. Time measuring device 5
A specific example will be explained later in FIGS. 3 and 4.

The time measurement gc device 5 is called when the control device 4V detects that the called communication terminal device 3 is in use in response to an incoming call. Time is taken out. The in-use information transmitting device (hereinafter referred to as the information transmitting device 9) 6 receives all the in-use information including the elapsed usage time from the control device 4, and sends the received in-use information to the control device 4 via the main switch l. It is sent to the calling communication terminal device 3 connected to 19.

The operating procedure will be explained with reference to FIG. 2 and all of FIG. 1.

FIG. 2 is a flowchart showing an example of the main operating procedure of the control device shown in FIG. 1. First, when the terminal review 81 is started up from one of the relay lines 82 (operation procedure 1), it is determined whether or not there is an incoming call to one of the terminal lines 81 (operating shell 2). In the case of an incoming call between terminals, the control device 4 further determines whether or not the called terminal is a ``fox'' (operator 3).
do. When in use, the control device 4 controls the called communication terminal device-3.
The usage time of is taken out from the time measurement device 5 as the elapsed time (
Operation procedure 4) Controls the main switch 1 and transmits the information to the information sending device 6
All calls are connected to the 100th floor device 3, and the information sending device 6
The in-use information including the used armor p and the replacement armor transit time fee is transferred and notified (operation step 5), and the operation is completely terminated.

Action element: When the called terminal review 81 is empty in shell 3.

The control device 4 completes the incoming call connection (operation procedure 6), and notifies the time measurement device 5 of the start of use of the communication terminal device 3 to start measuring time (operation procedure 7). In addition, if the call is not to the hotbed line 81 in operation procedure 2, the control device 4 makes a full judgment (operator ll1
8) L: In the case of a call, the call is connected (operation procedure 9), and the process continues to the operator j ridge 7, which notifies the time measuring device 5 of the start of the toilet and starts measuring the toilet time.

On the other hand, if the call is not from the terminal-to-terminal m81 in operation step 8, the control device 4 determines that it is a relay call and continues the relay call (operation step 10).

The second number expansion means 523 is activated when the i-terminal line is connected in response to an incoming call, and when activation is rare. Enter the terminal number of line 21 and the drive number 18'', expand it to the terminal number, and make it possible to pass through one gate 524 corresponding to the terminal number. The gate 524 outputs the clock pulse received from the clock circuit when the gate enters the passing state, and inputs it to the clock pulse input terminal CP of the calculation storage block of the corresponding terminal number of the elapsed time calculation storage means 522. The elapsed time calculation storage means 522 counts all the received 1M clock pulses to form and store the elapsed time. The third number expansion means 525 inputs the terminal number and release number 18 of the corresponding terminal device when the terminal line is in the released state, and calculates and stores the elapsed time from the corresponding terminal number in the corresponding storage means 522. An erase signal is sent to the reset terminal hole S of the terminal number calculation storage block, and the stored elapsed time is erased, and the gate 524 is also changed from the passing state to the closed-open state.
