Description

Apparatus for selective terminal calling using caller ID in codeless phone}

The present invention relates to each terminal call of a wireless telephone, and in particular, in a wireless telephone capable of using a fixed terminal and a plurality of portable terminals, a dedicated reception number for each terminal is designated by using a caller ID reception function. By having a function to execute and execute the call, the ringer is ringed selectively to each terminal at the time of the call, ensuring the privacy of the individual in the joint user and minimizing the invasion by other users. It relates to a terminal dedicated call device using the reception function.

In general, a wireless telephone is considered to be convenient when performing communication by connecting to a trunk line of a public telephone network, and includes one fixed terminal and a plurality of portable terminals.

In such a wireless telephone, the fixed terminal is directly connected to the trunk line, and each mobile terminal exchanges radio signals with the fixed terminal in a predetermined frequency band.

That is, by implementing a function unit for wireless transmission and reception in the fixed terminal and the portable terminal gives some spatial mobility to the user of the portable terminal and provides convenience to each terminal user as if they occupy the trunk line.

However, wireless telephones do not allocate and operate trunk lines for each terminal, but cause a problem due to sharing one trunk line between terminals.

The problem with the operation of the prior art radiotelephone is that it is not possible to determine which terminal of the terminal the call calls when there is a call arrival. Therefore, selective call forwarding or reception for each terminal has not been implemented.

Therefore, the incoming call to the radiotelephone emits ring tones for all terminals, which often generates unnecessary noise.

In addition, since the user of another terminal may simply listen to the contents of the call between the caller and the receiver using a random terminal, the privacy is not guaranteed, and this causes the inconvenience of infringing the life of the joint user. It was.

Therefore, the present invention is proposed to solve the above-mentioned conventional problems, and an object of the present invention is to use a caller ID reception function in a wireless telephone that can use a fixed terminal and a plurality of portable terminals. By assigning and executing a dedicated reception number for each terminal, by ringing the ring signal selectively for each terminal when the call is called to ensure the privacy of the individual within the joint user and life by other users The present invention provides a terminal-only calling device using a caller ID reception function in a wireless telephone suitable for minimizing infringement.

In order to achieve the above object, a dedicated device for calling a terminal using a caller ID receiving function in a wireless telephone according to the present invention includes: a dedicated call control stage for comparing a caller ID with a dedicated call number to determine whether to call a dedicated call; A CID detection unit detecting a caller ID through a trunk line; The technical configuration is characterized by consisting of a wireless unit for wireless communication with the mobile terminal.

Hereinafter, the configuration and operation of the present invention will be described based on the embodiment of the present invention according to the technical idea of the terminal-only calling device using the caller ID receiving function in the wireless telephone according to the present invention.

First, Figure 1 is a block diagram of a terminal dedicated calling device using a caller ID receiving function in a wireless telephone according to an embodiment of the present invention.

As shown in FIG. 1, a suitable embodiment of the present invention registers a dedicated call number and compares it with a caller ID detected by the CID detection unit 12 to determine whether or not the dedicated call control stage 13, 14, 16); A CID detection unit 12 for detecting a caller ID through the trunk line; And a wireless unit 15 for wireless communication with the mobile terminal.

The operation of the device configured as described above is as follows.

The device proposed by the present invention can be applied to a wireless telephone using a plurality of portable terminals in one fixed terminal. At this time, in order to enable a dedicated call of a terminal, a dedicated call number must be assigned to each terminal, and a means for calling each terminal based on the dedicated call number is required.

In Figure 1, the fixed terminal exchanges a voice signal to the trunk line through the audio unit (11). The audio unit 11 is a basic functional unit for trunk line calls.

The CID detection unit 12 monitors the trunk line and detects a caller ID transmitted by the exchange system of the public telephone network.

The controller 13 controls the overall operation of the fixed terminal and the portable terminal.

The memory unit 14 stores a dedicated calling telephone number and a designated device number designated by the user, and the wireless unit 15 communicates with each mobile terminal using a radio signal of a predetermined frequency band.

On the other hand, the numbering and mode setting by the user is made through the key input unit 16.

An operation of receiving a caller ID and performing a dedicated call will be described in more detail.

First, the user designates a dedicated call phone number for each terminal through the key input unit 16. The dedicated call number and the terminal information input to the key input unit 16 are stored in the memory unit 14 by the control unit 13.

In this operation, a basic setting for implementing a dedicated call function by receiving a caller ID is made.

In the state where the setting is made, the user determines whether to activate the dedicated call mode using a specific button of the key input unit 16. The determination of whether to activate the dedicated call mode may be performed for each terminal. For example, the fixed terminal and the portable terminal 3 are set to release the dedicated call and set to the dedicated call active only for the portable terminal 1 and the portable terminal 2.

In addition, since the portable terminal has a keypad and wireless communication is possible between the portable terminal and the fixed terminal, the setting of the dedicated call mode may be performed through each portable terminal without being limited to only the fixed terminal.

For example, when the dedicated call mode is set through the mobile terminal 1, information on the setting of the dedicated call mode is received by the wireless unit 15 of the fixed terminal. The dedicated call mode setting information received by the wireless unit 15 of the fixed terminal is recognized by the control unit 13 to confirm the mode setting.

When the ring signal and the caller ID are received through the trunk line while the dedicated call mode is set as described above, the CID detection unit 12 detects the ring signal and the caller ID and notifies the control unit 13.

Then, the control unit 13 checks the comparison between the dedicated call number registered in the memory unit 16 and the caller ID and activates the dedicated call mode.

If the caller ID matches the number registered as the dedicated call number as a result of the comparison check and the dedicated call mode of the terminal registered with the dedicated call number is activated, the ring tone is transmitted only to the corresponding terminal.

For example, if the number '0000' is registered as the dedicated call number of the mobile device 1 and the caller ID received when the mobile device 1 is set to the dedicated call mode is '0000', the other terminal does not ring. Instead, the ring will ring only on the mobile device 1.

In this way, the dedicated call function is implemented.

In other cases, it is difficult to determine which user to call, so it is reasonable to transmit ring tones to all terminals.

That is, if the detected caller ID is not registered as a dedicated call number and registered as a dedicated call number but the dedicated call mode of the corresponding terminal is released, the ringer is ringed to all terminals as in a normal wireless telephone. do.

As such, the present invention registers a dedicated call number for each terminal in a wireless telephone equipped with a plurality of terminals, and when the caller ID is the same as the registered dedicated call number, only the corresponding terminal is called to implement a dedicated call function. .

While the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Therefore, the above description does not limit the scope of the present invention defined by the limits of the following utility model registration claims.

As described above, the terminal-only calling device using the caller ID reception function in the wireless telephone according to the present invention utilizes a wireless telephone while ensuring maximum privacy of a user in a wireless telephone that can use one fixed terminal and a plurality of portable terminals. There is an effect that does not reduce the convenience of.

In addition, when a call is received from a phone number registered as a dedicated call number, a ring tone is selectively ringed for each terminal, thereby maximizing the advantage of using multiple terminals as one phone number.
