  The invention according to claim 3 includes an identification unit for identifying a communication carrier of a destination of the created electronic mail, and the adding unit adds only a code corresponding to the communication carrier of the transmission destination. It is characterized by.

  According to the present invention, between communication terminals corresponding to different telecommunications carriers, even if the telecommunications carrier's original pictograms, character modifications, etc. are included in the e-mail and transmitted / received normally, the characters are not garbled Can be displayed.

Hereinafter, a communication terminal according to an embodiment of the present invention will be described with reference to the drawings.
In the present embodiment, a mobile phone will be described as an application example of a communication terminal.
Also, the conversion method will be described by taking pictograms as an example.

FIG. 1 is a conceptual diagram showing an outline of a communication system in which a mobile phone having a pictogram conversion function according to an embodiment of the present invention is used.
The mobile phones 11 and 12 are communication terminals having a pictogram conversion function according to the embodiment of the present invention.
The mobile phone 11 corresponds to, for example, the in-house standard of the first communication carrier, and can create and send / receive e-mails using a pictographic code unique to the first communication carrier.
In addition, the mobile phone 11 can add a pictograph created with a pictograph code unique to the first communication carrier to the e-mail.
Here, the pictogram is a concept including an icon, and includes an illustration drawn by a combination of character data or symbol data.
Furthermore, the mobile phone 11 has another function described later, which can add a code (data) to an e-mail for pictograms defined by a communication carrier other than the first communication carrier.

The mobile phone 12 corresponds to, for example, the internal standards of the second communication carrier, and can create and send / receive e-mails using pictographic codes unique to the second communication carrier.
In addition, the mobile phone 12 can add a pictograph created with a pictograph code unique to the second communication carrier to the e-mail.
Further, the mobile phone 12 has another function that can add a code (data) to an e-mail for pictograms defined by a communication carrier other than the second communication carrier.

The wireless communication network 2 is a wireless communication network including a network of a first communication carrier and a second communication carrier to which the mobile phones 11 and 12 are connected.
The gateway 3 is a device that enables communication by mutually converting data of different media or protocols on a network.
That is, the gateway 3 absorbs differences in communication media and transmission methods and enables connection between different models.
The IP network 4 is a communication network based on the Internet protocol.
The wireless communication network 2 and the IP network 4 are connected by a gateway 3.

The mail servers 51 and 52 are computers that are always connected to the IP network 4 and transmit and receive electronic mail related to their own users.
For example, the mail server 51 is a mail server managed by a first communication carrier, and the mail server 52 is a mail server managed by a second communication carrier.
Thus, for example, an e-mail transmitted from the mobile phone 11 to the mobile phone 12 is received by the mobile phone 12 via the wireless communication network 2, the gateway 3, the IP network 4, and the mail servers 51 and 52. Displayed on the telephone 12.

Next, details of the mobile phone 11 will be described with reference to FIG.
FIG. 2 is a block diagram showing the configuration of the mobile phone 11.
It is assumed that the mobile phone 12 has the same configuration as the mobile phone 11.
The mobile phone 11 includes an antenna 111, a wireless unit 112, a control unit 113, a voice processing unit 114, a transmission unit 115, a reception unit 116, an operation unit 117, a display unit 118, and a storage unit 119.
The storage unit 119 stores pictographic information 120 in advance.

The antenna 111 and the wireless unit 112 are configured to convert call contents or e-mails into wireless signals and transmit / receive them.
The control unit 113 controls each unit of the mobile phone 11 and includes a CPU and the like.
The voice processing unit 114 processes a voice signal input from a microphone or the like constituting the transmitting unit 15 and a voice signal output from a speaker or the like constituting the receiving unit 116.
The operation unit 117 includes a power key, a call start key, a call end key, numeric character keys, a jog key for displaying various menus, and the like.
By operating the operation unit 117, calls, mail creation, mail transmission / reception, and the like can be performed.

The display unit 118 displays contents of mail creation / editing, contents of received mail, various settings for the mobile phone 11, and the like.
The storage unit 119 stores various programs and data that define the operation of the control unit 113.
In addition, the storage unit 119 is data corresponding to all currently existing telecommunications carriers (for example, the first telecommunications carrier, the second telecommunications carrier, etc.), and is a pictograph made up of tags and pictographic data forming pictograms. Information (each carrier code) 120 is stored.

Next, the transmission / reception operation of the e-mail with pictographs in the mobile phones 11 and 12 will be described with reference to FIG.
FIG. 3 is an explanatory diagram showing the transmission / reception operation of the mobile phones 11 and 12.
First, the user creates an e-mail by operating the operation unit 117 while referring to the display unit 118 of the mobile phone 11 (S1).
For example, a character is input such as “Today, the weather is nice and I will go to the car wash”.
In this creation, a pictograph is selected and used instead of the word in the character (S2).
For example, instead of the word “car”, a car picture (car pictogram) is input.
Many types of pictographs such as a car picture are stored in advance in the storage unit 119 as pictographic information 120.

Next, by operating the operation unit 117, the content of the e-mail including the pictograph edited in steps S <b> 1 and S <b> 2 is determined and further temporarily stored in the storage unit 119.
Then, data <emoji1> is inserted into the pictogram portion of “car” in the contents of the e-mail (S3).
This <emoji1> data is a part of the pictographic information 120, and is a pictographic tag suitable for all currently existing communication carriers.

Next, by operating the operation unit 117, the e-mail confirmed and stored in step S3 is transmitted to the mobile phone 12, for example.
Information indicating that the pictograph is quoted is added to the header information of the e-mail transmitted here.
The information indicating that the pictograph is cited is, for example, “<emoji1> = aaa @ ez; bbb @ jph; ccc @ doc;” (S4).
In the information indicating that this pictograph is cited, for example, “aaa @ ez” indicates a pictographic code unique to the first communication carrier, “bbb @ jph” indicates a pictographic code unique to the second communication carrier, “Ccc @ doc” indicates a pictographic code unique to the third communication carrier.
Therefore, a pictograph of “car” appears on the display unit 118 of the mobile phone 11 with a pictographic code of “aaa @ ez”.

Next, the cellular phone 12 receives the email transmitted from the cellular phone 11 in step S4 (S11).
Then, the control unit 113 of the mobile phone 12 determines that the header information of the received e-mail includes information indicating that the pictograph is quoted, and notifies the display unit 118 of the determination result.
Then, the display unit 118 of the mobile phone 12 reads the pictographic code applied to the second communication carrier from the pictographic information of the received e-mail, skips the pictographic codes applied to the other communication carriers, and stores them. The pictograms are read from the part, developed into the display buffer, and displayed.
Therefore, a pictograph of “car” appears on the display unit 118 of the mobile phone 12 with a pictographic code of “bbb @ jph” (S12, S13).

Thus, according to the mobile phones 11 and 12 of the present embodiment, when an e-mail is created on the e-mail sender side using a special pictogram unique to a certain communication carrier, the information indicating the pictogram is displayed. Pictograph information (carrier-specific code) 120 suitable for a plurality of carriers can be added.
In addition, the mobile phones 12 and 11 on the receiver side can select and display pictographic information suitable for the terminal from the pictographic information 120 included in the received e-mail.
Therefore, according to the present embodiment, even if the mobile phone 11 and 12 corresponding to different telecommunications carriers include a pictograph unique to the telecommunications carrier in an e-mail and is sent and received, the garbled characters are not garbled and transmitted normally. Can be displayed.

In the above embodiment, the presence or absence of a pictogram is identified by the header information of the mail, but the presence or absence of a pictogram may be identified based on a tag of the pictogram.
Similarly, the presence or absence of character modification may be identified by a tag, and a code to be applied to each communication carrier may be added.

In addition to the above-described embodiment, a communication carrier as a communication destination may be identified and only a code applied to the communication carrier as a communication destination may be added.
In this way, by limiting to only codes that are applied to the communication carrier of the transmission destination, it is possible to reduce the data amount of the e-mail to be transmitted.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the specific structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
