Description

Phone capable of displaying calling party number and speed dialing and method

The present invention relates to a telephone capable of displaying a caller's telephone number and speed dialing in a telephone communication system and a method thereof.

In general, the answering machine automatically generates a voice prompt message to the caller when the user is absent or difficult to answer the call. Play a role. By the way, the automatic answering device may not be provided separately, or even if the automatic answering device is provided, it is inconvenient because the user needs to input the corresponding numeric key one by one in order to redial the caller's telephone number. In addition, some telephones function to store and store a caller's telephone number from an exchange when there is an incoming call, but the procedure of checking the caller's telephone number and redialing if desired is very cumbersome.

Accordingly, an object of the present invention is to provide a telephone and a method capable of pre-recognizing a caller when a call is generated.

Another object of the present invention is to provide a telephone and a method capable of short-dial dialing later without additional confirmation of a call that has been missed.

In order to achieve the above object, the present invention provides a telephone, comprising: a signal processor for receiving a caller's telephone number information provided by an exchange and performing predetermined signal processing; one or more speed dial keys; And a memory for storing a telephone number in correspondence with an arbitrary speed dial key, and a controller for transmitting the caller's telephone number to a dialer when dialing of the speed dial key is detected.

According to a second aspect of the present invention, there is provided a method for displaying a caller's telephone number on a telephone and speed dialing the telephone number, the method comprising: receiving a caller's telephone number related information from an exchange and a caller's telephone; A second process of visually displaying the caller's telephone number by signaling the number related information, a third process of storing the caller's telephone number in correspondence with a predetermined speed dial after displaying the caller's telephone number, and an arbitrary shortening When the input of the dial key is detected, a fourth process of reading a caller's telephone number corresponding to the speed dial key from the memory and transmitting the dialer number to a dialer is performed.

1 is a block diagram of a caller's telephone number display and speed dialing telephone and its peripheral device according to an embodiment of the present invention

2 is a detailed configuration diagram of the called subscriber telephone 100 of FIG.

3A and 3B are flowcharts illustrating processes of executing a caller's telephone number display and speed dialing according to an exemplary embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. Also, in the following description, many specific details such as components of specific circuits are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It is self-evident to those of ordinary knowledge in Esau. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a telephone and a speed dialable telephone and its peripheral device according to an embodiment of the present invention. Reference numerals 100 and 400 denote incoming and outgoing subscriber telephones. Reference numeral 300 is a switch, which has a subscriber-specific database 340 for storing talk time and the like as shown, and transmits a caller's telephone number to the called subscriber's telephone 100 based on the data registered in the database 340.

2 is a detailed configuration diagram of the called subscriber telephone 100 in FIG. The controller 210 collectively controls the overall operation of the phone and may be implemented as a one chip microprocessor having a ROM and a RAM. The ROM is masked with a control program and related data for controlling the operation of the phone and the display and speed dialing of the caller's telephone number as shown in FIG. 3 to be described later. The Line Interface Unit (LIU) 230 realizes the interface between the telephone line (T, R: tip, ring) and the telephone by matching signals. The ring detector 220 detects a ring signal transmitted through a telephone line and notifies the controller 210 of an incoming call. The dual tone multi frequency (DTMF) detector 250 decodes the DTMF signal received through the LIU 280 and provides digital tone information to the controller 250. In this embodiment, the caller telephone number related information received from the switch 300 takes the form of digital tone information. The memory 270 stores the caller's telephone number received from the exchange 300, and may use EPI. The display unit 290 visually displays the caller's telephone number read from the memory 270 under the control of the control unit 210. The date or time of the call may also be displayed together with the caller's telephone number. The key input unit 300 is a user interface unit and includes one or more shortcut dial keys.

3A and 3B are flowcharts illustrating processes of executing a caller's telephone number display and speed dialing according to an exemplary embodiment of the present invention.

Referring to FIG. 3A, the controller 210 checks whether a ring signal is detected through the ring detector 220 in step 3A. At this time, if the detection of the ring signal is detected, in step 3B, the information related to the caller's telephone number provided from the exchange is received and processed. In step 3C, the processed caller's telephone number is displayed on the display unit 290. In step 3D, the user checks whether the user hooks off the phone number. At this time, if the user hooks off, the call is connected and the call is made in a known manner. On the other hand, if the hook-off is not detected, the process proceeds to step 3E to check whether a predetermined time has elapsed, and if a predetermined time has elapsed (this means that the user is not present or intentionally does not answer the call). To the speed dial buffer of memory 270.

3B is a flowchart illustrating a process of speed dialing a caller's telephone number stored by FIG. 3A. When an arbitrary speed dial key input by the user is detected in step 4A, in step 4B, the speed dialer buffer of the memory 270 is accessed to read the stored caller telephone number. Then, in step 4C, the read caller's telephone number is transferred to the dialer 280 to automatically dial.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention is capable of pre-recognition of a caller when a call is generated, so that it is possible to eliminate prank calls and the like.
