Description

How to send ring signal from cordless phone

The present invention relates to a method for transmitting a ring signal in a wireless telephone, and more particularly, to a method for transmitting a ring signal in accordance with a set number of ring-offs in a wireless telephone.

Typically, the phone detects the ring signal applied through the ring terminal and the tip terminal and transmits the detected ring signal when the call is received.

In the conventional telephone, the ring off function does not unconditionally transmit a ring signal detected when an incoming call is received from the outside. When the ring-off function is set in the conventional wireless telephone, it is inconvenient because the user does not transmit the ring signal even when the user calls the mobile device from the fixed device to find the mobile device. In addition, even if the user forgets to set the ring off function of the telephone, there is a problem in that the incoming call is not known because the telephone does not transmit the ring signal.

Accordingly, an object of the present invention is to provide a method of transmitting a ring signal by adjusting a set number of ring-offs in a telephone.

Another object of the present invention is to provide a method for automatically releasing a ring off function in a wireless telephone.

Another object of the present invention is to provide a method for transmitting a ring signal by giving priority to ring reception between a fixed device and a plurality of portable devices in a radiotelephone having a fixed device and a plurality of portable devices.

In order to achieve the above object, the present invention provides a process of setting the number of ring-offs when the ring-off function is set in the telephone, and determining whether the ring-off function is set when an incoming call is made. And a process of interrupting the transmission and transmitting a ring signal when the set number of times of the ring-off is greater than or equal to the set ring-off number.

3 is a diagram illustrating a process of transmitting a ring signal in a wireless telephone according to an embodiment of the present invention, and transmits the detected ring signal according to the setting of the ring off function.

A method of transmitting a ring signal in a wireless telephone according to an embodiment of the present invention will be described with reference to FIGS. In step 310, the control unit 100 of the stationary device of the wireless telephone receives the signal output from the ring detector 104 and determines whether the ring signal applied through the telephone line is detected. Meanwhile, the control unit 200 of the portable device of the wireless telephone receives a signal corresponding to whether a ring signal is detected from the fixed device through the wireless unit 210, and determines whether the ring signal is detected. If the ring signal is not detected, the controllers 100 and 200 of the wireless telephone terminate the control operation according to the embodiment of the present invention.

When the ring signal is detected in step 310, the control unit 100 of the fixed device of the wireless telephone in step 320 determines whether to set the ring off function by searching the memory 101. On the other hand, upon detecting the ring signal, the controller 200 of the portable apparatus of the wireless telephone determines whether to set the ring off function with reference to the setting data of the ring off function stored in the memory 201. If the ring-off function is not set, the controllers 100 and 200 of the radio telephone transmit the ring signals to the speakers 109 and 231, respectively.

If it is determined in step 320 that the ring off function is set, in step 330, the control unit 100 of the fixed device of the wireless telephone sets the ring by referring to the setting data of the ring off function stored in the memory 101 according to an embodiment of the present invention. It is determined whether or not a ring signal is detected more than the number of off times. For example, in a specific embodiment of the present invention, when the number of ring off settings is five, the controller 100 determines whether five or more ring signals are continuously detected from the ring detector 104. On the other hand, if the ring-off function is set, the control unit 200 of the portable device of the radiotelephone applies the ring signal more than the set number of ring-off times by referring to the setting data of the ring-off function stored in the memory 201 according to an embodiment of the present invention. Determine whether or not. If less than the set number of ring-offs, the control unit 100 determines whether the ring signal is applied more than the set number of ring-offs by performing a control operation from step 310.

When a ring signal is detected more than the number of ring-off setting times, in step 340, the control unit 100 of the fixing device of the wireless telephone transmits a ring signal applied through the speaker 109. On the other hand, if the ring signal is detected more than the number of ring-off setting times, the controller 200 of the portable apparatus of the wireless telephone outputs the received ring signal to the speaker 231.

When the radiotelephone according to the embodiment of the present invention is composed of a fixed device and a plurality of portable devices, the number of ring-off settings according to an embodiment of the present invention may be determined according to the priority of the fixed device and the plurality of portable devices. Set it differently. Then, the wireless telephone according to the embodiment of the present invention sequentially transmits a ring signal to the fixed device and the plurality of portable devices according to the incoming priority.

As described above, according to the present invention, the position of the portable device can be easily determined by giving a difference in ring transmission time between the fixed device and the portable device in the radiotelephone.
