If the same as one of a plurality of specific message codes set in advance in the wireless call caller corresponding to the specific message code matched by a caller with a caller text display function that can easily recognize the caller and its display method It is about.

Currently, there is a widespread wireless call receiver that uses a landline telephone to notify a call message wirelessly in a state where it is impossible to make a direct call with the receiver. According to the wireless call receiver, when a number of a wireless call receiver is called by a wired subscription telephone. A dial tone or alarm tone is generated to indicate that there is a call to the radio call receiver, while a call message such as the caller's telephone number is displayed on the indicator.

1 is a block diagram illustrating a conventional radio call receiver, in which an antenna 10 and a high frequency signal received through an antenna are mixed with a local oscillation signal, and then frequency down to output a difference frequency signal as an intermediate frequency (IF) signal. A converter 12, a demodulator 14 that demodulates the IF signal, and a decoder that receives and decodes the digitally converted signal of the demodulated analog signal to determine whether the address of the received message matches the unique address. A microprocessor (CPU) 18 for controlling all functions by receiving an output signal of the decoder unit, a memory 20 for storing a system control program and storing the received message; And a vibration motor / buzzer 22 for notifying the reception of the message, and an indicator 24 for displaying the telephone number and reception time of the received caller.

Generate a melody to indicate receipt of a message. However, in this case, since the message displayed on the indicator 24 displays only the caller's phone number, there is an inconvenience in that it is not easy to know the caller, and there is a problem that it is difficult to confirm the time when the call message is received.

On the other hand, a text service that can leave a text memo of about 120 characters using a wireless call receiver (aka text pager) capable of text display has recently been implemented. In this method, when the user selects a text service when making a wireless call and leaves a voice, the contents are recorded at the exchange of the wireless calling service provider, and then the contents are read and the recorded message is input instead of the text. By combining with, and transmitting the radio call signal, the message recorded in the called party's receiver is displayed in Korean characters.

However, such a text service must first purchase a text service for the service provider at the same time as the purchase of the text pager, pay a service fee for providing the text service every month, and deliver the recorded message instead of text. There is a problem that a message is leaked to others.

Therefore, the present invention has been made in view of the problems of the prior art, the object of which is that a specific part of the received wireless call message or message in advance without receiving a separate text service application or service fee to the wireless caller in advance to the receiver Provides a wireless call receiver having a caller text display function that can easily recognize the caller by displaying the wireless call caller corresponding to the matched specific message code in the case of one of a plurality of specific message codes set up, and a display method thereof It is.

(Example)

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

3 is a schematic block diagram illustrating a configuration of a radio calling receiver according to the present invention, FIG. 4 is a flowchart illustrating a caller display process of the radio calling receiver shown in FIG. 3, FIG. Display example of the indicator, Figure 6 is an example of the conversion table for converting the radio call originator for a particular message code, Figure 7a to Figure 7c is an example showing a method of inputting a specific message code during radio call in accordance with the present invention.

First, referring to FIG. 3, the wireless call receiver according to the present invention mixes the high frequency signal received through the antenna 101 and the local oscillation signal with the local oscillation signal similarly to the conventional method, and then converts the difference frequency signal into an intermediate frequency (IF) signal. A frequency down converter 102 for outputting, a demodulator 104 for demodulating the IF signal, and a digitally converted signal of the demodulated analog signal are received and decoded so that the address and the unique address of the received message match. A decoder 106 for judging the error, and a microprocessor (CPU) 108 for controlling all functions by receiving the output signal of the decoder.

In addition, the CPU 108 has a conversion table for converting a control program required for overall system control including a caller text display operation as shown in FIG. 4 and caller text information corresponding to a specific message code as shown in FIG. The ROM 110 stored therein and a RAM 112 for temporarily storing data being processed are connected.

On the other hand, on the output side of the CPU 108, a data output unit 114 for driving the indicator 116 made of the LCD shown in FIG. 5 to display a message according to an incoming call, and for notifying the incoming call in the beep mode. A buzzer 118 for generating a beep sound and a vibration motor 120 for generating vibration in order to notify an incoming call in the silent mode are connected.

In addition, on the input side of the CPU 108, a read switch SW1 used to read a received message or to confirm a condition shown on the indicator 116, and when selecting various function switching, number change, message lock or unlock, and individual deletion. A key input section 122 is connected which includes a function switch SW2 to be used and a selection switch SW3 to be used for function selection, movement and lamp operation.

In this case, the switches SW1-SW3 of the key input unit 122 may be changed to 2-5 depending on the preparation of the control program.

The receiver also includes a clock generator 124 for supplying a system clock signal to the CPU 108 and a reception time generator 126 for providing a reception time when an incoming call occurs according to the control program.

The caller display process of the wireless call receiver according to the present invention configured as described above will be described in detail with reference to FIGS. 5 and 6.

First, when the user makes a wireless call, when the user enters the caller's phone number, the user inputs a specific message code shown in FIG. 6 in addition to the caller's phone number, for example, 101 (see FIG. 7A) or vice versa. Enter a specific message code first and continue to enter the calling party's telephone number (see Figure 7b), or if you already know the calling party's telephone number, enter only the specific message code (see Figure 7c).

As shown in FIG. 6, the specific message code can distinguish the wireless call originator by group according to the highest number of the codes. For example, you can set 100 codes as family, 200 codes as coworkers, and 900 codes as friends.

Accordingly, the radio call exchanger makes an input signal, for example, in a POCSAG signal format, modulates it, and transmits the radio signal.

Accordingly, the radio call receiver mixes the RF signal received through the antenna 101 with the local oscillation signal after mixing the high frequency amplification and the amplified high frequency signal by the frequency down converter 102 and converting the difference frequency signal as an intermediate frequency (IF) signal. Output

Thereafter, when the intermediate frequency signal is demodulated by the demodulator 104 and an analog signal is output, an analog / digital conversion (not shown) is performed and applied to the decoder 106.

The decoder 106 detects a preamble and word sync of the received POCSAG signal and decodes the received message. Subsequently, if the address continuously received is compared with its own unique address ID, the CPU 108 notifies the data reception, and the clock generator 124 also generates a clock according to the data reception.

In this case, if the unique address of the decoder 106 and the received address do not coincide, the reception of data is stopped and invalidated.

The CPU 108 then determines which particular portion 101 of the received data being received corresponds to one of the specific message codes contained in the ROM 110, and if there is a corresponding specific message code, the corresponding sender, i.e. The FATHER data is stored in the RAM 112 together with the reception time.

Subsequently, the CPU 108 operates the buzzer 118 or the vibration motor 120 according to the set reception alarm mode and simultaneously applies the caller data to the data output unit 114 to the display 116 as shown in FIG. 5. Likewise, the caller is indicated by text. In this case, the characters displayed on the display unit 116 can be displayed in English or the native language (for example, Korean) by storing the caller information of the conversion table stored in the ROM 110 as English or Korean character data. .

Thus, the user can easily recognize the sender by recognizing the message displayed by the text displayed on the indicator 116.

4 is a flowchart illustrating a caller display process of the radio call receiver shown in FIG. 3. The caller display process will be described in detail as follows.

First, when the power of the radio receiver is supplied to the power-on state, all the functions of the system are initialized accordingly. Then, when the caller makes a radio call, the receiver undergoes a demodulation process and demodulated data is applied to the decoder 106.

Accordingly, when a call message is received (S1), it is determined whether the reception address matches its own address (ID) (S2). If the result of the determination is consistent, the message is continuously received (S3). Return to step S1 to determine whether or not to receive the paging message again.

Subsequently, it is determined whether the specific part of the received message corresponds to one of the plurality of specific message codes shown in FIG. 6 (S4). As a result of the determination, when a specific message code is included in a specific part, the reception time of the call message and the call message is stored in the RAM 112 (S5), and then, for example, in the display unit 116, the specific part is 101. The buzzer 118 or the vibration motor 120 are operated in accordance with the set reception alarm mode while reading and displaying the character data FATHER corresponding to the caller from the conversion table (S6, S7).

However, if the specific part of the received message does not match any one of the plurality of specific message codes as a result of the determination, the received message, that is, the caller's telephone number is displayed on the display unit 116 and the received alarm mode is set accordingly. Operate the buzzer 118 or the vibration motor 120 (S8, S9).

Meanwhile, at the same time as the caller indication, a timer (not shown) is set for a certain time to monitor whether the timer is out, and if the read switch SW1 of the key input unit 122 is operated before the timer is out, the stored reception time is displayed ( 116) (S10-S12).

After that, the timer is continuously monitored, and when the read switch SW1 of the key input unit 122 is operated before the timer is out, the stored sender's text data is displayed on the display 116 (S13-S15).

Similarly, if the read switch SW1 of the key input unit 122 is operated before the timer is out, the stored reception time is displayed. If the read switch SW1 is not operated, the current time is displayed on the display unit 116. Enter the initial state (S16-S19).

As described above, in the present invention, the caller can be easily recognized by providing a conversion table that corresponds to a 1-to-1 correspondence between a specific message code and a character indicating a corresponding wireless caller. In this case, it may be an option to use a series of numbers, for example, 111 or 222, so that a user easily memorizes a specific message code and a corresponding sender type.

In this case, the number of digits of the specific message code is not fixed to three digits as in the embodiment, but may be set to an appropriate digit as necessary. It is also possible to enter a specific message code instead of entering the caller's phone number to display the caller only in text.

As described above, in the present invention, when the specific part of the received wireless call message is the same as the specific message, the indicator can be easily recognized by zooming by displaying the sender as a regular sentence on the indicator. According to the display, it is possible to confirm the identity of the caller who is fast and accurate, and improve the merchandise.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and is not limited to the spirit of the present invention. Various changes and modifications can be made by those who have
