Description

  The present invention relates to a mail communication method and a communication system, and more particularly to a mail communication method for transmitting and receiving mail including pictograms and a communication system in which the mail communication method can be used.

  Conventionally, mobile communication terminal devices such as mobile phones have been widely used. In such a mobile communication terminal device, in addition to a voice call function, a mail function (creation of a mail text, transmission / reception of mail, display of received mail text, etc.) is generally provided.

  In the exchange of e-mails using this e-mail function, pictographs are frequently used because the e-mail text can be shortened and, in addition, it has an effect such as a pleasant appearance as compared to monotonous sentences with only letters. A mail including such pictograms (hereinafter also referred to as “pictogram mail”) is created in the mobile communication terminal device on the transmission side using a pictographic database held by the mobile communication terminal device on the transmission side. The created pictographic mail is transmitted from the mobile communication terminal device on the transmission side to the mobile communication terminal device on the reception side. In the mobile communication terminal device on the receiving side, the received pictographic mail is decoded and displayed using the pictographic database held by the mobile communication terminal device on the receiving side.

  By the way, the registered contents of pictograms in the pictogram database of the mobile communication terminal device differ depending on the model of the mobile communication terminal device. For this reason, if the mobile communication terminal device on the transmission side (that is, the creation side) and the mobile communication terminal device on the reception side are different, when the mail text is displayed on the reception side, so-called garbled characters occur. Therefore, display as intended on the transmission side cannot be performed on the mobile communication terminal device on the reception side.

  In order to improve these points, the following method has been proposed (see Patent Document 1; hereinafter referred to as “conventional example”). In this conventional example, a pictographic database corresponding to each model is stored in a pictographic server in the mobile communication network. Then, the application that operates in the mobile communication terminal device that has received the pictographic mail downloads the pictographic information included in the pictographic mail, that is, the pictographic font corresponding to the pictographic code included in the pictographic mail from the pictographic server. With reference to the downloaded pictogram information, the mobile communication terminal apparatus that has received the pictogram mail displays the received pictogram mail without so-called garbled characters.
