Abstract

(57) [Abstract] [Purpose] A message creating device for creating message data in a pager for sending and receiving a message using a telephone wireless station, for example, when the end of the message is a free word. Prevents the effective length of the message from being unnecessarily reduced without adding a release code. [Structure] When creating message data, a free word is converted into a POCSAG code and input. A start code "-" is added at the beginning and a release code "_" is added at the end to distinguish it from other POCSAG symbols. In the pager to be converted, if there is a free word at the end of the created message data, the release code “_” added to the end is deleted, so the number of digits that can be transmitted is unnecessary. It is not occupied, and it is possible to prevent the substantial length of the message from being reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a message creating device used in a paging system or the like for sending and receiving messages.

[0002]

2. Description of the Related Art Conventionally, when a third party calls a pager by inputting a telephone number, a telephone radio station transmits an ID code corresponding to the input telephone number.
By the pager having the code to notify the reception,
It is used as a portable communication device for personal calls.

[0003] In such a pager, not only a model in which a user is simply notified by the generation of an electronic sound or the like to make a call, but also a message input from a third party together with a pager telephone number of a callee is also included. Models that can be received and displayed on the display unit for confirmation are also widely used.

Here, the message that can be transmitted to the pager is created by the arrangement of numbers and characters, but since the input means is limited to the telephone, the input of characters (for example, IUEO ...) Is a combination of two digits. It is input and created by.

In this case, inputting a message by characters is called "free word input". That is, if you specify free word input and enter "1" and "1" on the telephone dial, for example, it will be treated as "A", and if you enter "1" and "2", it will be treated as "A".
When "1" and "3" are input, they are treated as "C".

On the other hand, for data transmission between a telephone and a telephone station, and between a telephone radio station and a pager, 16 types of POCSAG symbols including numbers 0 to 9 represented by 4 bits are used. It

[0007] In the message transmitted as the array of POCSAG symbols, when the free word represented as a combination of the two digits and the symbol information represented by a simple numeral are mixed, the array of free words is arranged. Since it is necessary to distinguish between the symbol sequence and the numerical array of symbol information, a start code "-" is added to the beginning of the free word and a release code "_" is added to the end of the free word using the symbols in the POCSAG symbol. ing.

That is, when the message to be transmitted is a mixture of the free word and the symbol information, for example, "A1", the form of the transmission data becomes "111" without the discrimination code added, and at the receiving side. Since it cannot be determined, the discrimination code is added and transmitted as "--11_1".

Here, when the free word is input, the start code "-" is always added to the beginning of the free word, and the release code "_" is added to the end of the free word. Even if it is configured by the above and it is not necessary to distinguish the end thereof, the release code “_” is added and transmitted.

[0010]

As described above, if the cancellation code is added even when the end of the input message is a free word, the number of digits that can be used for data transmission is unnecessarily occupied by one digit. Therefore, there is a problem that the length of the substantial message is reduced.

The present invention has been made in view of the above problems. For example, when the end of the message is a free word, the cancellation code is not added and the substantial message length is wasted. It is an object of the present invention to provide a message creation device capable of preventing the message generation from being reduced.

[0012]

That is, the message creating apparatus according to claim 1 of the present invention is configured such that the second type data represented by a combination of the first type data and the first type data. An apparatus for creating message data wirelessly communicated by using an identification code that adds an identification code indicating that the data is the second type in the case of creating the second type of data. Code addition means and, when the first type of data follows the second type of data, adds an end code indicating that the second type of data has ended after the second type of data And if it doesn't continue,
An end code control means for controlling such that the end code is not added is provided.

A message creating device according to a second aspect of the present invention is the message creating device according to the first aspect, in which the first type of data is numeric data and the second type of data is Characteristic data represented by a combination of two numerical data is characterized.

A message creating device according to claim 3 of the present invention is the message creating device according to claim 2, wherein the message data created using the numeric data and the character data is used over a telephone line. It is characterized by further comprising a transmitting means for transmitting to the other pager via the paging system.

[0015]

That is, in the message creating device according to the first aspect, the identification code indicating that the data is the second type is added before the data of the second type, and the data of the second type is also added. If the data of the first type follows the data, an end code indicating that the data of the second type is the end is added to the data of the second type, and if it does not continue, the end Since the code is controlled so as not to be added, it is possible to prevent the end code for the second type data from being added unnecessarily.

According to a second aspect of the present invention, there is provided the message generating device according to the first aspect, wherein the first type of data is numeric data and the second type of data is numeric data. Since the character data is represented by a combination of the two, the message data is created using the numeric data and the character data, and the end code for the character data is prevented from being added unnecessarily.

Further, in the message creating device according to claim 3, in the message creating device according to claim 2, the message data created by using the numerical data and the character data is a paging system using a telephone line. It will be sent to the other pager via.

[Kana / number] provided as the key input unit 21 in the message creation / transmission process in FIG.
When the free word input mode for inputting Kana characters is set by operating the key 17, the free word input process in FIG. 5 is started (step S1 → SA).

Here, as shown in FIG. 8A, when the character input key 18 is operated to input "A" to display it on the liquid crystal display unit 12, first, the input character is the first input character. If it is determined that the input character is the first input character, the start code "-" indicating the beginning of the free word is written in the message register in the RAM 25 (step A1 → A2).

The kana character "a" displayed by key input is converted into a POCSAG code "11" according to the POCSAG conversion correspondence table in FIG. 3, and the free word start code "-" is followed by the R.
It is written in the message register in the AM 25 (step A3).

When the characters of the free word are keyed in, converted into a code and stored, the free word release code "_" is input immediately thereafter and written in the message register in the RAM 25 (step A4). .

Thus, the free word "A" is input and displayed, and "--11" is displayed in the message register in the RAM 25.
When “_” is stored, the release code process in FIG. 6 is activated (step SA → SB).

In this cancellation code processing, first, it is judged whether or not the character of the message input immediately before is a free word (step B1). In this case, when it is determined that the free word “A” is input, the RAM
It is determined whether or not the free word release code “_” exists at the end of the message data stored in the message register 25 (step B1 → B2).

In this step B2, by inputting "Yes", that is, "A" of the free word, the message register in the RAM 25 becomes "--11".
When it is determined that "_" is stored and the release code "_" is present at the end, the release code is deleted from the message register, and the state is stored as "--11" (step B3).

That is, when the end of the message data is a free word, the release code "_" added to the end thereof is deleted. Thus, the step SA
(Free word input processing) and step SB (release code processing), the free word “A” is input and displayed.
In the state where “−-11” is stored in the message register in the RAM 25, the “Kana / number” key 17 provided in the key input unit 21 is further operated to input a number.
Switch to the CSAG symbol input mode and enter the character input key 18
When you operate and input "1", the liquid crystal display 12
The number "1" input by the number this time is displayed together with the "A" input by the free word, and "-111" is stored in the message register in the RAM 25 (steps S2 → S1 → S3).

When the process goes to the release code process in FIG. 6, first, it is judged that the input is not a free word, and further it is judged whether or not the previous input mode was the input mode of the free word "FW". (Steps B1 → B4).

If it is determined in step B4 that "Yes", that is, the input mode immediately before the current number "1" is input, is the free word input mode in which the kana character "a" is input, As shown in FIG. 8 (B),
In the message register in the RAM 25, the free word release code "_" is inserted before the input number "1" and stored as "--1_1" (step B4).
→ B5).

That is, even after the free word "a" is once input and the cancellation code "_" is deleted, if the POCSAG symbol "1" is subsequently input,
In the message register in the RAM 25, a cancellation symbol “_” is inserted between “11” indicating the free word “A” and the POCSAG symbol “1” to distinguish them.

On the other hand, as shown in FIG. 8B, the free word character "A" and the numeral "1" are input and displayed, and "--11_" is displayed in the message register in the RAM 25.
When the free word “a” is inserted by moving the cursor to the number “1” displayed on the liquid crystal display unit 12 in the state of storing “1”, first, the message creation process in FIG. Then, the process proceeds to the free word input process (step S1 → SA).

Then, in the free word input process in FIG. 5, it is determined that the input free word "a" is not the first free word, and the input and displayed free word "a" is the same as that shown in FIG. POCSAG in 3
According to the conversion correspondence table, the POCSAG code "1"
2 "converted to RAM corresponding to the position immediately before the cursor position
It is inserted and written following the release code "_" of the free word "a" stored in the message register in 25 (step A3).

At this time, the message register in the RAM 25 is in the state of being stored as "--11_121". The letters "i" in the free word are "a" and "1"
When the code is converted into a code and stored after being converted, a free word release code "_" is input and written in the message register in the RAM 25 (step A4).

Thus, the free word "a" is inserted and displayed, and "--11" is displayed in the message register in the RAM 25.
_12_1 ”is stored, the release code process in FIG. 6 is activated (step SA → SB).

In this release code processing, first, it is determined that the free word "a" has been input as the character of the message input immediately before that, so the end of the message data stored in the message register of the RAM 25 is terminated. Then, it is judged whether or not the free word cancellation code "_" exists (step B1 → B2).

At this step B2, if "No", that is, if it is determined that the end of the message data currently stored in the message register of the RAM 25 is the numeral "1" and not the release code "_", this time. POCSAG code “1” corresponding to the inserted free word “A”
It is determined whether or not the release code “_” exists immediately before “2”, that is, whether or not the free word is input subsequent to the free word (steps B2 → B6).

In step B6, "Yes", that is, the PO corresponding to the free word "A" inserted this time.
When it is determined that the release code “_” exists immediately before the CSAG code “12”, the release code is deleted and R
The message data stored in the message register in the AM 25 becomes "--1112_1" (step S6).
→ S7).

That is, when a free word is input between a free word and a numeral, only the release code "_" added to the last end of the free word is left and the distinction from the numeral is achieved.

On the other hand, as shown in FIG. 8B, the free word character "A" and the numeral "1" are input and displayed, and "--11_" is displayed in the message register in the RAM 25.
1 ”is stored, the“ delete ”key 14 provided in the key input unit 12 is operated, and as shown in FIG.
When the number "1" input at the end of the message data is deleted, the message creation process in FIG. 4 proceeds to the deletion process (step S1 → SC).

Then, in the deletion process in FIG. 7, first, the number "1" which is the deletion target is deleted (step C1). In this case, the message data stored in the message register in the RAM 25 becomes "--11_", and it is determined whether the end of the message data is the cancellation code "_" (step C2).

In this case, since it is determined that the cancellation code "_" exists at the end of the message data after the numeral "1" is deleted, the cancellation code "_" is deleted and the RAM 25 is stored. The message data stored in the message register becomes "--11" (step C2).
→ C3).

That is, when the input message data is partially deleted and the end is a free word, the release code added to the end is unnecessary and is deleted.

In this way, with the arbitrary message data input and displayed, and the code data stored in the message register in the RAM 25, the telephone number of the destination pager is dialed by the push line telephone, and the key input unit 12 is pressed. When the "send" key 15 provided in the telephone is operated, the coded message data is output from the tone output section 26 as a DTMF signal, transmitted to the telephone radio station via the receiving microphone of the telephone, and is wirelessly transmitted. It

Therefore, according to the pager equipped with the message creating device having the above-mentioned structure, when creating message data, the free word is converted into the POCSAG code and input, and the start code "-" is added to the beginning of the POCSAG code and the end of the free word is added to the end. In a pager in which a release code “_” is added to distinguish it from other POCSAG symbols, if a free word exists at the end of created message data, the release code “_” added to the end of the free word. Is deleted, the number of digits that can be used for data transmission is not unnecessarily occupied, and it is possible to prevent the substantial length of the message from being reduced.

[0060]

As described above, according to the message creating apparatus according to the first aspect of the present invention, the identification code indicating that the second type data is added before the second type data. If the second type data is followed by the first type data, an end code indicating that the second type data is finished is added after the second type data. If the end code is not continued, the end code is controlled so as not to be added, so that the end code for the second type data is prevented from being added unnecessarily.

According to a second aspect of the message creating apparatus of the present invention, in the message creating apparatus according to the first aspect, the first type data is numeric data.
Since the second type of data is character data represented by two combinations of numerical data, message data is created using the numerical data and the character data, and the end code for the character data is added in vain. Will be prevented.

According to the third aspect of the present invention, there is provided the message producing apparatus according to the second aspect, wherein the message data produced by using the numerical data and the character data uses the telephone line. It will be sent to the other pager via the existing paging system.

Therefore, according to the present invention, for example, when the end of the message is a free word, the substantial message length is prevented from being unnecessarily reduced without adding the release code. Will be possible.
