3. Summary of Solution to Invention

After the dialing lock function is set, when the parallel-connected telephone is hooked off, a call loop is formed to send out a roaring or holding sound to the telephone line to control the transmission of the parallel-connected telephone.

4. Important uses of the invention

Applies to outgoing control of telephones connected in parallel to cordless telephones.

Description

Call Locking Method for Telephones Connected to Cordless Telephones in Parallel

1 is a block diagram of a wireless telephone according to the present invention

2 is a flow chart for controlling the outgoing lock of the parallel connection telephone according to the present invention.

The present invention relates to a transmission lock method of a wireless telephone, and more particularly, to a transmission lock method for controlling the transmission of a telephone connected in parallel to the wireless telephone.

In general, a cordless telephone (Cordlless telephone) is a cord that changes the cord of the ordinary telephone to a fixed device connected to the telephone line, and to communicate wirelessly with the fixed device for voice telephony communication through the telephone line. Speak phone. By the way, many cordless phones are connected to the cordless phone in parallel, and the use of the cordless phone may cause the phone to be unusable. If you do not use the parallel connected phone when there was a problem that can not answer the call.

Accordingly, an object of the present invention is to provide a dialing lock method of a telephone for controlling the dialing of a telephone connected in parallel to a wireless telephone to solve the above problems.

Another object of the present invention is to provide a dialing lock method for controlling a dialing out of a parallel-connected telephone by transmitting a roaring or holding sound to a telephone line when using a telephone connected in parallel by setting a dialing lock function.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a wireless telephone according to the present invention, wherein a key input unit 10 generating a dialing lock key signal and a hook-off of a telephone connected in parallel when a dialing lock key signal is input from the key input unit 10 are shown in FIG. A control unit 12 for detecting a state and generating a roar or hold sound to be sent to the telephone line, and a use state detecting unit for detecting the use of the telephone 22 connected in parallel by checking the voltage drop of the telephone line ( 14), a use state display unit 16 which displays the use state of the telephone 22 connected in parallel by the control of the control unit 12, and forms or cuts a call path under the control of the control unit 12; And a call circuit unit 18 for transmitting a loud or suspended sound generated from the control unit 12 to a telephone line, and a handset 20 connected to the call circuit unit 18 for a voice call.

2 is a flow chart for controlling the outgoing lock of the parallel access telephone according to the present invention.

The operation of the preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2 described above.

In order to carry out the present invention, an outgoing lock should be set, and outgoing lock setting is performed by pressing the outgoing lock key provided in the key input unit 10 and at this time, a password may be registered together. And the control part 12 contains the part for transmitting and generating a loud sound or a reserved sound.

First, in step 101, the control unit 12 sets the call lock function state when the call lock key is input from the key input unit 10. In step 102, the controller 10 checks whether the ring signal is received and controls to generate a ring when the ring signal is received. In step 103, the control unit 12 checks whether the wireless telephone 24 or the parallel connection phone 22 is hooked off, and if the device is hooked off, proceeds to step 104 to form a call with the hooked-off telephone.

However, when there is no ringing in step 102, the control unit 12 checks whether the telephone 22 connected in parallel from the use state detecting unit 14 is hooked off. At this time, if the parallel-connected telephone 22 is hooked off, a voltage drop is generated in the telephone line, and the use state detector 14 detects the occurrence of the voltage drop and detects the hook-off state of the parallel-connected telephone 22. Detect. When the hook-off state of the parallel-connected telephone 22 is detected, the control unit 12 proceeds to step 106 to control the call circuit unit 18 to form a call loop, and then generate a loud or pending sound generated from the control unit 12. To the telephone line. Therefore, the user of the parallel-connected telephone 22 will not be able to attempt a call and will put down the handset. At this time, in step 107, the control unit 12 checks whether the phone 22 connected in parallel is in the hook-on state, and if it is not in the hook-on state, the control unit 12 returns to step 106 and continuously emits a roaring or holding sound. However, when the parallel-connected telephone 22 is in the hooked-on state, the flow proceeds to step 108 and the control unit 12 controls the call circuit unit 18 to block the call loop and stop transmitting the loud or held sound and enters the idle state. .

As described above, the present invention controls the outgoing of the telephones connected in parallel to the radiotelephone, so that it is possible to accurately receive the scheduled call at a desired time and to prevent others from being stolen by the telephone line.

In addition, by locking the outgoing time in the home unnecessary, there is an advantage that can prevent the children from attempting to call during the night.
