Abstract

PURPOSE:To execute recognition for discriminating an important part in a message within irreducibly minimum time by making the display form of a character string part with routine meaning different from the display form of a figure string part with arbitrary and important meaning. CONSTITUTION:When a selective call number in a receiving signal is coincident with a call signal stored and set into a memory element 4 of its own receiver in advance, the presence and absence of a first control signal 9 in a following signal is detected by a detection part 5 in a decoder 3. When the first control signal is detected, a decoder 6 decodes a 5th character string stored and set to the memory element 4, which is determined in advance, corresponding to a 4th code train 10 next following and displays the character string in a display part 8 with full size display. When the first control signal is not detected, a 6th character stored and set to the memory element 4, which is determined in advance, is decoded and displayed in the display part 8 with half size display.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an individual selective call receiver with display (hereinafter referred to as a receiver).

[Conventional technology]

In recent years, the environment surrounding receivers has seen a large number of operational service companies being established based on the major principles of telecommunications liberalization, and the demand for receivers themselves has increased accordingly.

With the rapid increase in demand, the flow of demand is changing from tone-only receivers that notify incoming calls by simply ringing to receivers with numeric displays that can display numeric information, and even to receivers with character displays. However, since conventional receivers with character display do not have a simple means of inputting characters on the caller's side, telephones equipped with a DTME transmission function use a code indicating a fixed phrase predetermined by the operation service company, and a fixed phrase example. is selected by number, the caller inputs only the numeric message, and the base station equipment of the operation service company converts it into a text message string with predetermined standard phrases corresponding to the number selected by the caller. The majority of systems use a system in which a message is combined with a numeric message (check pit) 13 input by the caller to form a text message to call the receiver.

On the other hand, in a conventional receiver with a numeric display, a number or string of numbers (parity bit) 14, which has a meaning between the calling party and the called party, and a string of arbitrary numbers 16 are used to display one number. The majority of methods involve composing a message and calling a receiver.

According to the above method, the receiver with character display displays the predetermined "NEC 03# standard character string 1" as shown in FIG.
5 and an arbitrary number string 16, and in a receiver with a number display, a number string 17 of "11" whose meaning is predetermined as shown in FIG. 6, and another arbitrary number string 18 are particularly distinguished. It is supposed to be displayed on a single display means.

[Problem to be solved by the invention]

In the display means of the conventional receiver described above, all message information is displayed in a single display format, and therefore has the following disadvantages. That is, (1) In a receiver with a character display, if a number string exists in a character string in a fixed phrase, care must be taken to distinguish it from an arbitrary number string.

■ On a receiver with a character display, if the fixed text is a character string that includes kanji, the aspect ratio of the numbers in the arbitrary number string display is t.
It becomes about xt, and there is a feeling of discomfort.

■ For receivers with numeric displays, care must be taken to distinguish between numeric strings with predetermined meanings and arbitrary numeric strings.

There is a drawback.

SUMMARY OF THE INVENTION An object of the present invention is to provide an individual selective calling receiver that solves the above problems.

[Means to solve the problem]

In order to achieve the above object, an individual selective calling receiver according to the present invention receives and demodulates a carrier wave modulated by a selective calling signal and a message signal following the selective calling signal, and outputs a predetermined own selective calling number and the demodulated signal. In an individual selective calling receiver, the receiver notifies the user of the call only when the called number matches the message signal, and has a display section that displays characters or character message strings decoded from the message signal. means for detecting a control code; means for decoding a character message string from a fourth code string of a predetermined length following the first control code and displaying it in a second display format; and a message signal. The apparatus further includes means for decoding characters from codes other than the first control code and the fourth code string, and displaying the characters in a third display form.

〔Example〕

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a circuit block diagram of an individual selective call receiver with display according to the present invention.

FIG. 2 is an operational flowchart regarding the present invention.

FIG. 3 is a code format diagram for the present invention.

FIG. 4 shows display means related to the present invention.

In the figure, l is an antenna, 2 is a radio section, and the radio section 2 receives and demodulates the carrier wave modulated by the selective call signal and the message signal that follows it, and sends it to the decoder 3 as a digital signal of 11" or "0". The decoder 3 compares its own calling number pre-stored in the memory element 4 with the received and demodulated selective call signal, and if they match, operates the call notification means preset in the memory element 4. a detection unit 5 that sends an operation signal to the call notification unit 7 and detects the presence or absence of the first control code 9 in the message signal;
It has a decoder 6 for decoding a fifth character string or a seventh character whose correspondence is set in advance in the storage element 4 from the fourth code string lO or the sixth code string 11.

The memory element 4 is an EFROM or an electrically erasable E
It is composed of at least one or a combination of EROM or RAM equipped with a backup battery, and includes at least a selective calling number of the receiver, a calling notification means, and a fourth code string! A fifth character string or a seventh character corresponding to 0 or the sixth code string 11 is stored in a built-in window.

Reference numeral 7 denotes a call notification unit which receives a call notification operation signal from the decoder 3 and operates one or a combination of a speaker LED or a vibrator, which is a call notification means, to notify a call. A display section 8 displays the fifth or seventh character string decoded by the decoder 6 in the decoder 3 on a dot matrix LCD.

9 is the first control code, which is an 8-bit @1" string.
O is the fourth code string, which is 4 which is the decimal conversion of two decimal digits.
This is a bit x 2 code string.

11 is the sixth code string, and each code represents one character with 4 bits, but if all 4 bits are +11", it is difficult to distinguish it from the first control code 9. Therefore, 15 types of characters are represented by 4 bits.

Also, 12 is the address/message flag (l bit)
, 13 are check bits (10 bits), and 14 is a parity bit (1 bit).

When the receiver in the standby state matches the selective calling number in the received signal with the calling number stored and set in advance in its own storage element 4, it decodes the following signal.

The detection unit 5 in the decoder 3 detects the presence or absence of the first control code 9 in the above-mentioned successive signals, and after this, the operation of the decoder 6 in the decoder 3 is divided into the following two cases. It will be done.

■ When the first control code 9 is detected by the detection unit 5,
The decoder 6 decodes the fifth character string stored in the predetermined storage element 4 corresponding to the fourth code string lO that follows.

In this embodiment, it is assumed that the fourth code string "0001" obtained by decimal conversion of the two-digit "11" in lO base is set in advance to the fifth character string "9NEC 03".4 After the fourth code string of bits x 2 is completed, the display unit 8 displays the character string in the tube 5 using the second display means.In this embodiment, the second display means is a means for displaying in full-width display. shall refer to.

After the above-mentioned display means has ended, it is detected whether or not the message signal has ended, and if the message signal has not ended yet, it returns to the detection operation state of the first control code 9, and if it has ended, it returns to the standby state. Return to

■ If the first control code 9 is not detected by the detection unit 5, the decoder 6 detects the sixth character stored in the predetermined storage element 4 corresponding to the next succeeding sixth code string 11. decrypt.

In this example, the sixth code string “oooo” obtained by decimal conversion of the 1-digit “O” in lO base is converted into the seventh character “10”, and the “1” is converted to “l” through the sixth code string “0001”. The seventh character “9” is the sixth code string”+001
The 6th code string is decoded into the 7th character every 4 bits, and the display unit 8 displays it on the third display means. .

In this embodiment, the third display means means a means for displaying in half-width display. After the above-mentioned display ends, it is detected whether or not the message signal has ended, and if the message signal has not ended yet, it returns to the detection operation state of the first control code 9, and if it has ended, it returns to the standby state. .

〔Effect of the invention〕

As explained above, the present invention relates to display means of a receiver.
a character string portion having a predetermined fixed meaning;
By differentiating the display format of the numerical string parts that are arbitrary and have important meanings, there is an effect that the important parts within the message can be distinguished and recognized in the minimum amount of time necessary.
