JPH08289045A - Telephone set with automatic termination function - Google Patents

Abstract

PURPOSE: To avoid a disable state of other incoming calls due to a long phone call or due to a state of a continuous talking in mistake and to prevent a communication charge to be huge. CONSTITUTION: A control section 8 controlling the operation of a telephone set is provided with a memory 9 storing a speech permission time set by a key entry section 4, a timer 10 measuring a speech time from speech start and a comparator section 11. The comparator section 11 compares the speech time with the set permissible time, rings a predict tone in a prescribed time before the expiration of the set permissible time and conducts termination processing of the telephone set automatically when the speech time reaches the permissible time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone set, and more particularly to a telephone set with an automatic call termination function that can set a call time and automatically terminate the call.

[0002]

2. Description of the Related Art A conventional telephone has a function of displaying a call allowable time and notifying the user of the fact that a certain time has elapsed from the start of a call by sound or the like. With such a conventional function, the user can be alerted to a call for a long time.

FIG. 3 is a block diagram of a conventional mobile phone. In the figure, 1 is a radio unit, 2 is a modulation / demodulation unit, 3 is a control unit for controlling the operation of the entire telephone, and has a built-in CPU (central processing unit). Reference numeral 4 is a key input unit, 5 is a speaker, 6 is a microphone, and 7 is a display unit. Although a mobile phone is shown as an example, a wired subscriber phone is directly connected to a cable without the radio unit 1 and the modulation / demodulation unit 2.

[0004]

However, since the conventional telephone only calls attention to a long-time call, the user forgets that "the call is in progress" during the call. In this case, or when an infant who does not intend to make a call operates the telephone and enters a call state, the call line is maintained forever. In such a situation, even if there is an incoming call from another, it is "busy", so new incoming calls cannot be received, and in addition, the call charges are accumulated and enormous charges must be paid. is there.

An object of the present invention is to automatically terminate the call state when a preset time has elapsed from the start of the call, so that the call state is not unnecessarily maintained and a new call It is to provide a telephone with an automatic end function capable of receiving an incoming call.

[0006]

In order to achieve the above-mentioned goal, a telephone with an automatic call ending function according to the present invention has a function of automatically ending the call after a preset time has elapsed from the start of the call. Further, the gist is that a notification sound is emitted at a certain time before the automatic end of the call, and a function of notifying the user of the end of the call is provided. The configuration is a telephone including a key input unit for inputting a telephone number and other information, a monitor for operating state and a display unit for received data, a speaker, a microphone, and a control unit for controlling the operation of the entire circuit. In the control unit, the control unit stores a call allowable time designated and input from the key input unit, a timer unit that counts a call time from the start of a call, a call time output from the timer unit, and the memory. And a comparator that compares the call allowable time with a comparator, and when the call time reaches a certain time before the call allowable time, a ringing end notification sound for notifying that the call allowable time will end is sounded from the speaker. The call termination processing is performed when the call allowable time is reached.

[0007]

In the present invention, when the call end time input from the input unit is stored in the storage unit and compared with the output of the timer for counting the call time, when the call end time and the call end time match, The control unit automatically ends the call and puts it on-hook. Therefore, when the user has no intention of making a call, the call is not unnecessarily held and a new incoming call from another person can be received.

[0008]

FIG. 1 is a block diagram showing an embodiment of the present invention. Reference numerals 1, 2 and 4 to 7 in the figure show the same parts as in the conventional block diagram of FIG. Reference numeral 8 is a control unit to which the function is added according to the present invention. In the control unit 8, a memory 9 for storing the call end time set and input from the key input unit 4, and a timer unit 1 for counting the call time from the start of the call.
0 and a comparison unit 11 that compares the call time counted by the timer unit 10 with the set call end time stored in the memory 9 are provided.

The above technical means has the following functions. (1) A function to set the automatic end time (hours: minutes). (2) A function of counting the set time by using the timer of the CPU or the LSI (the clock function of the LSI if the LSI has a clock function) of the control unit. (3) It has the function of automatically ending the call when the count of the timer section reaches the set call end time, and the software automatically performs the hook state release, the line end process of the line, and the standby state setting process. (4) Has an automatic end-of-call notification function that sounds before automatic end of call,
The announcement sound can be selected by the user from several types.

FIG. 2 is an operation flowchart of the present invention, and 20 to 24 are step numbers. The call allowable time is set in advance and stored in the memory 9 from the key input unit 4. When the call is started, it is determined in step 20 whether the automatic call end timer function is active. When the call is being started, in step 21, the time from the start of the call counted by the timer unit 10 is compared with the call allowable time set in the memory 9 by the comparison unit 11. If the call time is still within the allowable time, the next 22. If the time is up, the call ending process is performed. In step 22, a predetermined time before the set call end time, for example, one minute before is set as the designated notice time, and it is determined whether or not the designated notice time is reached. When the designated notice time is reached, the process proceeds to the next step 23, the automatic end-of-call notification sound is emitted, and the process proceeds to the next step 24. If not yet reached, the process proceeds to step 24 to continue counting and return to the first step 20.

Although the above embodiment has been described with respect to a mobile phone, the present invention can be applied not only to a mobile phone but also to a home wired phone. The case of application is shown below. In the case of a mobile phone, even if you do not end the call (on-hook) during a call, if the other party ends the call, you will not be talking for a long time. It will take a few minutes at the longest, depending on the carrier company. On the other hand, in the case of a general wired telephone, even if the other party hangs up during the call, the other party cannot receive the other call even if the call charge is not paid because the receiver is off. Does not ring). For example, when a child hits a telephone and the receiver goes off-hook, a state in which the child cannot receive a call occurs. Even in such a case, after a certain period of time has elapsed, the call is automatically terminated, and if you receive a call later,
You can enter the call state by performing hooking operation.

[0012]

The following effects can be obtained by implementing the present invention. (1) It can be done by receiving a new incoming call. (2) Since the user can automatically end the call when the time set by the user comes, it is possible to prevent unnecessary accumulation of call charges.
