In step S510, when the control server receives an attachment conversion request from an email proxy server, the control server receives an email viewing request sent from an email client included in a mobile terminal that receives the notification information. Receiving a conversion request for an attachment of the email from a server, wherein the conversion request for the attachment includes a caller-name, a local file URL, and a mobile station identification number (MIN). do.
In step S520, when the control server receives the conversion target attachment file from the predetermined address information, the control server attaches the conversion target by connecting to either an email server or an email proxy server with reference to the address information of the local file UEL. Downloading the file.
In this case, the attached file includes a multimedia file such as a document file, an image file, a video file, and the like.
The step S530 of receiving a file conversion request from the control server by the file conversion server is performed when the attachment file requested from the email client included in the mobile terminal is not a file that can be viewed by a file viewer included in the mobile terminal. The file conversion server receives a file conversion request from the control server.
In step S540, the file conversion server converts the conversion target attachment file into a viewable form in the mobile terminal, and converts the conversion target attachment file into a viewable form in a file viewer included in the mobile terminal. Generating step.
In this case, when the conversion target attachment file is a document file or an image file, it may be converted by enlarging, reducing or rotating the image to be viewed by the mobile terminal.
In addition, when the conversion target attachment file is a document file, the file conversion server converts the first page of the document included in the conversion target attachment file, and if there is a request to view the next page from the mobile terminal to convert the remaining pages. Can be.
The file conversion server stores the converted file in the storage (S550). The file conversion server converts the file conversion server generated in step S540 of converting the attached file into a form that can be viewed in a mobile terminal. Storing the attached file in storage.
In step S560, when the control server receives the converted attachment file request from the mobile terminal, the control server receives the converted attachment file from the file viewer to the converted attachment file from the file viewer. Receiving a view request for.
In step S570, the control server transmits the converted attachment file to the mobile terminal so that the control server transmits the converted attachment file from the control server or the file conversion server to the file viewer through a wireless communication network. This step is to control.
At this time, when the converted attachment file is a document file, it is possible to minimize the traffic of the wireless communication network by controlling to transmit only a predetermined page requested from the file viewer.
