JPH02128558A - How to display the busy time of the other party's terminal on the telephone - Google Patents

Abstract

PURPOSE:To give a criterion for telephone recalling to an originating subscriber to prevent repeat of unnecessary calling by displaying the busy time of a destination terminal in accordance with the operation of an originating telephone terminal at the time when the destination terminal is busy when being called. CONSTITUTION:When a terminal A calls a terminal B, a CPU 2 of an electronic exchange 1 sets channels 4 and 1 between terminals A and B by speaking state management parts 3 and 1 and starts to count the speaking time between terminals A and B by speaking time counting parts 3 and 2. When a terminal C calls the terminal B by telephone during this speaking, the terminal C dials a code to see the speaking time of the terminal B after hooking because the busy tone is returned to the terminal C. The CPU 2 reads the time counting counter of the terminal B in speaking time counting parts 3 and 2 and returns speaking time data to the terminal C, and the terminal C displays its contents on a display part C1. Thus, a criterion for recalling is given to the originating subscriber to prevent repeat of unnecessary telephone call.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic exchange and a telephone equipped with a function capable of receiving and displaying call time, particularly when the other party's terminal is busy. The present invention relates to a service function that displays intermediate time based on an output request from a calling telephone terminal.

[Conventional technology]

Conventional Device IT As described in Japanese Patent Application Laid-Open No. 60-68750, a switchboard that recognizes a calling number and communicates the calling number to a telephone, and a telephone that can receive the calling number. It was a system consisting of.

[Problem to be solved by the invention]

The above conventional technology makes a call from a telephone terminal, and does not take into consideration the case where the other party's terminal is busy, and the function cannot be used until the other party's terminal answers, and the call cannot be made. There was a problem that needed to be continued.

The object of the present invention is to send the call time of the destination terminal in response to a request from the calling terminal when the destination terminal is busy;
The purpose of this display is to give the caller a guideline for making another call, thereby eliminating the need to repeat wasteful call operations.

[Means to solve the problem]

The above purpose is accomplished by software processing, and a timer counter waiting in an electronic exchange starts counting from the time when the response completion time of the other party's terminal is measured. The counter value is constantly updated and accumulated, and when the calling terminal issues a busy time display request, the calling terminal reads the counter value at that time to determine the talk time and sends the data back to the calling terminal. It becomes possible to output and display on the character display section.

[Effect]

The call time is counted by the timer that the exchange has itself, and the call time is determined based on the count data, so it matches the time held on hold at the exchange. Furthermore, even after a call is busy, a call time request from a calling terminal can be re-transmitted, including the call time request, by hooking the caller and dialing the access code. Thereby, the exchange transmits the call time, and the calling terminal receives and displays the call time data. Through the above operations, call time request and display are realized.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. In the figure, A and B are general telephone terminals, C is a telephone terminal with a character display function, 1 is an electronic exchange (EXC), 2 is the central processing unit (CPU) of the exchange, 3 is an exchange processing program, and 3.1 is a call status management In the section, 32 is a talk time measurement section, 4 is a time switch (TSW), and 5 is a bidirectional trunk (BWT).
It is.

When terminal A calls terminal B, the CPU 2 activates terminal B when it detects that terminal B is in an empty state by the call state management unit 3.1, and terminal B that blocks the call state is started and off'. When the response by f-Hook is completed, the CPU
2 sets up a call path 4.1 between terminals A and B, and also starts measuring the call time for terminals A and B by the call time measuring section 3.2. In the call time measuring unit 3.2, a counter is initially set to zero when the terminals A and B are activated, and when a call path is set, the counter starts counting based on the command from the CPU 2. After that, when terminal A and terminal B are talking, if terminal C makes a call to terminal B, the CP
U2 checks the call state management unit 3.1 and returns a busy tone to terminal C when it detects that terminal B is in a busy state. Therefore, after hooking up, terminal C dials a code to see how many minutes terminal B's current call has been busy. This causes CPU2 to connect terminal C before hooking.
When the terminal B number inputted by the terminal B and the call time request code after hooking are recognized, the call time measurement unit 3.2 recognizes the terminal B
Terminal C reads the time counter and sends the call time data back to terminal C. When the terminal C receives the call time data, it displays the contents on the display section C1. FIG. 2 shows a flowchart for counter operation, and FIG. 3 shows a flowchart for requesting and displaying call time.

According to this embodiment, even if the other party's terminal is busy, the call time of the other party's terminal can be displayed by operation from the calling terminal, which can be used as a guide for the caller to make a call again, thereby eliminating wasted phone calls. This has the effect of eliminating repeated transmissions.

〔Effect of the invention〕

According to the present invention, even if the other party's terminal is busy when making a call, the busy time of the other party's terminal can be displayed by operation from the calling telephone terminal, so the caller has no time to make another call. It can provide a guideline and has the effect of eliminating repeated unnecessary transmissions.
