Abstract

PROBLEM TO BE SOLVED: To simplify the operation by discriminating a character communication system from received character information and transmitting the character information according to the discriminated character communication system so as to eliminate the need for troublesome selection of the communication system of the transmission opposite party. SOLUTION: In the case that a character is entered before designation of a destination, when entry of character data is finished, presence of KANJI (Chinese characters) of the entered data and number of characters are discriminated, and when no KANJI is used and number of the characters is 20 characters or below, a system A with a limited character kind and a limited number of characters at a low cost is used and when not, a system B at a higher cost regardless of a higher degree of freedom of font type and number of characters is used to generate transmission data. When the data are generated, an address name corresponding to the discriminated character communication system is retrieved from a RAM: 19 and the addresses are listed on a display section 21, and the user selects an address (y) using a touch panel 22 and the data are transmitted to the selected address. Thus, a communication system corresponding to contents of the character data is automatically discriminated and the transmission operation can be transited by having only to optionally select a corresponding destination and then the user-friendliness can be enhanced.

The storage unit 18 is a control unit 17 that controls text communication and transmits and receives call data. The storage medium 18a stores a control operation program, character pattern data corresponding to character codes, and the like.

The RAM 19 has a transmission buffer for temporarily storing data including character communication data handled under the control of the control unit 17, a reception buffer, a flag register for setting various status flags, various counters, and the like. It has an address book memory 19a as shown in FIG.

That is, the address book memory 1 shown in FIG.
9a stores a plurality of sets of data in advance as one set of data including abbreviated numbers, names, addresses (telephone numbers), and corresponding character communication formats.

Here, as the corresponding character communication method,
For example, Hiragana, Katakana and Numerical symbols only up to 20
It is assumed that two systems are adopted: a character communication system A capable of transmitting characters, and a character communication system B capable of transmitting up to 1000 kanji characters in addition to hiragana, katakana, and numeric symbols.

In this case, although the character communication method A is limited in the character type and the number of characters, the cost required for communication is low.
It is assumed that the degree of spread is high. On the contrary, as shown in the figure, the character communication method B has a high degree of freedom in the character type and the number of characters, but requires a high cost for communication, has only a few corresponding terminals, and has a low degree of spread.

The contents stored in the address book memory 19a are always backed up regardless of whether the power switch is turned on or off.

The storage medium 18a of the storage device 18 is formed of a magnetic or optical storage medium or a semiconductor memory. The storage medium 18a is fixedly provided in the storage device 18 or is detachably mounted.

The program, data, and the like stored in the storage medium 18a may be configured to be received and stored from another device connected via a communication line or the like. Storage medium 18 on the other device side

The touch panel 22 is operated by the user with his / her finger or a special stylus pen (not shown) according to the display screen position. By performing a touch operation, the coordinate data of the operated position is stored in the control unit 1.
7 to input various characters.

Next, the operation of the above embodiment will be described.

FIG. 3 shows the contents of processing when a message is created by inputting character data and transmitted by the character communication function. The control is mainly performed by the control unit 17.

At the beginning, when transmission of character data is started, it is first determined whether or not character input is to be performed (step A01). This is determined by, for example, displaying a guide message such as “Character input first? / Destination specification first?” On the display unit 21 and detecting operation of any of them by the touch panel 22. .

Here, an operation for inputting characters is performed first, and when this is determined, the keyboard is displayed on the display unit 21 and the input on the touch panel 22 is sequentially received to thereby input the character data. The input is executed, and the input of the character data is stopped when the input end instruction is given (step A02).

When the input of the character data is completed in this way, it is subsequently determined whether or not the input character data contains kanji characters or whether or not the input character data is 21 characters or more in total (step A03). , A04), and determines which of the character communication system A and the character communication system B is most suitable for the input character data.

If it is determined that no kanji is mixed in the input character data and that the input character data is within 20 characters, it is determined that the input character data corresponds to the character communication system A. The transmission data based on the method A is created (step A05).

If it is determined that kanji is mixed in the input character data or that the input character data is 21 characters or more, it is determined that the input character data corresponds to the character communication system B. The transmission data based on the communication method B is created (step A06).

FIG. 4 shows an example of the data format of the character data created at this time. As shown in the figure, in this data format, a text identification code S2 indicating that the data is not text data but character text code data is added following a header S1 arranged at the head of the data. The actual data S3 which forms character data is added. The actual data S3 is variable-length data, and a system identification code S3a corresponding to the character communication system is added at the head position, and an end code S3b is added and set at the end. In each communication method, the data format may be sent after the communication path is connected, or the sub-address or UU of the call setting message may be transmitted before the communication path is connected.
It may be sent using I (user / user / information) or the like.

When the creation of the character data to be transmitted is completed, the address book memory 19a of the RAM 19 is searched by the determined character communication method (step A07), and the corresponding character communication method is set. The names of the addresses present are listed on the display unit 21 (step A).
08).

On the other hand, if an operation is performed to select and specify one of the names displayed in a list on the touch panel 22 (step A09), the above-mentioned creation is performed using the address corresponding to the specified name. The transmitted character data is transmitted (step A10), and the processing is completed.

In step A01, an operation for designating the address of the transmission destination is performed prior to the character input. If the operation is determined, the keyboard is displayed on the display unit 21 and the touch panel 22 is operated. The name of the destination address is designated by sequentially receiving the input (step A11).

Then, when the name of the address is input,
Next, the address book memory 1 of the RAM 19 is named by the name.
9a is retrieved (step A12), and the character communication system of the corresponding address is read (step A13).

Here, if there is only one character communication system read out, a guide message to that effect, for example, in the case of the character communication system A, "2 characters using kana characters and numeric symbols"
Create a message with no more than 0 characters. "Promptly prompts you to enter character data for the sent message.

When there are two read character communication methods, a guide message for selecting which method is used to create a message, for example, "" within 20 characters using kana characters and numeric symbols "" / "Kanji also includes 1
Which method do you use to create messages? Is displayed and a guide message prompting the user to input character data for a transmission message according to the selected character communication method is displayed when the selection is made.

Then, the keyboard is displayed on the display unit 21 and the input of the character data is executed by sequentially receiving the input on the touch panel 22, and the input of the character data is stopped when the input end instruction is given (step S1). A1
5).

When the input of the character data is completed in this way, the transmission data of the data format as shown in FIG. 4 based on the corresponding character communication system is created from the input character data, and the transmission data corresponding to the specified name is created. The generated character data is transmitted using the address to be processed (step A10), and the process is completed.

As described above, when the character data constituting the message to be transmitted is input earlier than the input of the destination, the character communication method corresponding to the contents of the actually input character data is automatically determined. Then, since it is possible to proceed to the transmission operation as it is simply by selecting an arbitrary destination from the destinations corresponding to the determined character communication method, the operation for selecting the character communication method and the address of the transmission destination are changed. The input operation can be greatly simplified, and usability can be greatly improved.

Further, even when the input for designating the destination address is made earlier than the input of the character data, it is possible to directly shift to the input of the character data in the character communication system corresponding to the address. Therefore, the operation for selecting the character communication method can be simplified.

Next, the operation when character data is received will be described.

FIG. 5 shows the contents of processing which is started when an incoming call is determined from the standby state and when it is determined that the incoming call is a result of character communication. Do.

At the beginning, character data is received (step B01), and whether or not the reception is successful, that is, the actual data S3 in the data format shown in FIG.
Then, it is determined whether or not the system identification code S3a added to the head of the character string corresponds to the character communication system of the own device (step B02).

Only when it is determined that the reception was successful, the sender data is searched from the address book memory 19a of the RAM 19 by the transmitted sender number (step B03).

Then, the name of the searched sender and the received character data are displayed together on the display unit 21 (step B04), and the received character communication method is the same as that of the sender who searched the address book memory 19a. It is confirmed whether or not it matches the character communication system stored and set in the data (step B05).

Here, only when it is determined that they do not match, it is assumed that the sender has transmitted character data in a character communication method other than the character communication method registered so far.
The character communication method of the character data sent to the sender data in the address book memory 19a is additionally stored (step B06), and the process ends.

As described above, even when the character communication method of the received character information is different from the character communication method stored in advance corresponding to the address of the sender, if the reception is successful, the transmission destination is newly changed. Since the communication by the character communication method is enabled, the content of the address book memory 19a is automatically updated and stored, so that the next time the character data is transmitted from the user to the sender, The range of character communication systems that can be selected can be expanded.

Next, another processing content at the time of transmission by the character communication function instead of the above-mentioned FIG. 3 is illustrated in FIG.

In the figure, first, a keyboard is displayed on the display unit 21 and input of character data is executed by sequentially receiving an input on the touch panel 22, and when the input end instruction is given, the character data is input. Stop (step C01).

When the input of the character data is completed, it is continuously determined whether or not the input character data contains kanji characters or whether the input character data is 21 characters or more in total (step C02, step C02). C03) It is determined whether the input character data corresponds to the character communication system A or the character communication system B.

If it is determined that no kanji is mixed in the input character data and that the input character data is within 20 characters, it is determined that the input character data corresponds to the character communication system A. The transmission data based on the method A is created (step C04).

If it is determined that kanji is mixed in the input character data or that the input character data is 21 characters or more, it is determined that the input character data corresponds to the character communication system B. The transmission data based on the communication method B is created (step C05). The data format of the character data created at this time is as shown in FIG.

When the creation of the character data to be transmitted is completed, the names of the stored addresses are displayed in a list on the display unit 21 from the address book memory 19a of the RAM 19 regardless of the character communication system (step C06). ).

On the other hand, when an operation is performed to select and designate one of the names displayed in a list on the touch panel 22 (step C07), the above-mentioned creation is performed using the address corresponding to the designated name. The transmitted character data is transmitted (step C08).

Thereafter, it is determined whether or not the transmission was successful (step C09). Only when it is determined that the transmission was successful, the character communication stored and set as the transmission destination data in the address book memory 19a is determined. The system information is read (step C10), and it is confirmed whether or not the transmitted character communication system matches the character communication system stored and set in the data of the transmission destination searched in the address book memory 19a (step C11).

Here, only when it is determined that they do not match, it is assumed that character data can be transmitted in a character communication system other than the character communication system registered so far.
The character communication method of the transmitted character data is additionally stored in the data of the same destination address in the address book memory 19a (step C12), and the process ends here.

As described above, even when the character communication method of the transmitted character information is different from the character communication method stored in advance corresponding to the address of the transmission destination, if the transmission is successful, the transmission destination is newly added. Since the communication by the character communication method is enabled, the contents of the address book memory 19a are automatically updated and stored, so that the character data can be transmitted to the destination again from here. It is possible to know the character communication method that can be reliably transmitted.

Although the above embodiment has been described with reference to a case where the present invention is applied to a PHS terminal, the present invention is not limited to this, and character data is communicated by a plurality of methods using different types of characters and different numbers of characters. As long as the mobile communication device can perform the communication, a digital mobile phone, a paging receiver, or the like may be used. The communication line (communication path) is not limited to the PHS, but may be a PSTN (Public Switch).
