Abstract

The method includes following steps: network side receives request of receiving E-mail with attachment sent from E-mail client end of mobile terminal; based on attribute of the attachment, the network side picks up interior data list including dada IDs inside the attachment, as well as sends text and the said list to the E-mail client end; the E-mail client end sends interior data IDs selected by user to network side; the network side sends data relevant to the data IDs to the E-mail client end. Network side carries out pretreatment for format of compressed files to be down loaded to client end, and for attachment in multiple page file formats in order to reduce unnecessary network flow as well as reduce requirement for storage and process capabilities at handset terminals.

Description

The processing method of e-mail attachment

Technical field

The present invention relates to a kind of processing method of e-mail attachment, the method that especially a kind of e-mail attachment that obtains at portable terminal is handled.

Background technology

Along with development of Communication Technique, the processing capacity of mobile phone is become stronger day by day, and can realize that the client software of the installation on the application mobile phone receives the function of Email, and is greatly convenient for users to use.Email is generally the file of text formatting, can attach the file of some other forms as annex simultaneously.

The existing mode that mobile phone receives Email is that the mobile phone Mail Clients is downloaded the text of mail and the annex of mail respectively, annex for any form, Mail Clients all is that annex is downloaded on the mobile phone, by the annex handling procedure of installing on the mobile phone annex is opened and is edited then.But annex for compressed format, if Mail Clients is directly downloaded the annex of this form, because the storage capacity and the disposal ability of PC terminal are all more intense, can normally finish processing for the Mail Clients on the PC terminal, but just need client software increase to resolve the function of compressed format annex for mobile phone terminal, and the realization of this function require than higher to the disposal ability of mobile phone.

And to the annex with the form demonstration of paging such as ppt, xls or pdf, if Mail Clients is with numerous these forms and annex that data volume is bigger is whole when downloading on the mobile phone, can cause huge network traffics, mobile phone also must possess certain storage capacity and disposal ability.The partial document content if the user only need read, and existing downloading mode is whole downloads, this had both caused waste of network resources and network congestion, had also improved user's use cost.

Summary of the invention

The processing method that the purpose of this invention is to provide a kind of e-mail attachment can selectively be downloaded the file in the Encapsulated PostScript according to user's needs.

Another object of the present invention provides a kind of processing method of e-mail attachment, can select the partial content in the annex of page format to download according to user's needs.

For achieving the above object, the invention provides a kind of processing method of e-mail attachment, form by following steps:

The request of the reception Email that the Mail Clients of the mail server mobile terminal receive of step 11, network side sends, described Email has the annex of compressed format;

The mail server of step 12, described network side is called in internal memory with the compressed format annex of this mail, and by the internal documentation listing of decompression module acquisition compressed format annex, described internal documentation listing comprises described annex internal file sign;

The mail server of step 13, described network side sends to described Mail Clients with the text and the described internal documentation listing of described Email;

The mail server of step 14, described network side receives the described internal file sign of choosing that described Mail Clients returns from described internal documentation listing;

The mail server of step 15, described network side will be sent to described Mail Clients after will decompressing with the described file identification corresponding file of choosing by decompression module.

The processing method of another kind of e-mail attachment provided by the invention, form by following steps:

The request of the reception Email that the Mail Clients of the mail server mobile terminal receive of step 21, network side sends, described Email has the annex with the paging mode displaying contents;

The mail server of step 22, described network side is called in internal memory with the annex of this mail, and described annex with the paging mode displaying contents is divided into a plurality of single page files;

The mail server of step 23, network side is set up page number sign for each single page file, generates the catalogue of single page file, and the text of described Email and the catalogue of single page file are sent to described Mail Clients;

The mail server of step 24, described network side receives the described page number that will the download sign of choosing that described Mail Clients returns from the catalogue of described single page file;

The mail server of step 25, described network side carries out the single page file corresponding with the described page number that will the download sign of choosing to be sent to described Mail Clients after the format conversion.

Therefore, the present invention has the following advantages:

The present invention is by requiring the compressed file format of download or the Email attachment of multiple page documents form to carry out preliminary treatment at network side to cell-phone customer terminal, both reduce unnecessary network traffic, reduced the storage capacity of the mobile phone terminal that docks receiving emails and the requirement of disposal ability again.

Below by drawings and Examples, technical scheme of the present invention is described in further detail.

Description of drawings

Fig. 1 is the flow chart of a specific embodiment of the present invention.

Fig. 2 is the flow chart of another specific embodiment of the present invention.

Embodiment

Figure 1 shows that the handling process of a specific embodiment of the present invention, present embodiment receives the Email that has compressed format (for example zip, rar, jar, tar or cab etc.) annex for the user with mobile phone, carries out following steps:

Step 101, mobile phone Mail Clients send request to the mail server of network side, and request receives Email, and this mail has the annex of compressed format;

Step 102, mail server are called in internal memory with the compressed format annex of this mail, prepare to handle;

Step 103, mail server pass through the internal documentation listing that inner decompression module obtains the annex of compressed format, have comprised the file identification of each internal file in this tabulation;

Step 104, mail server send the text of this Email and the internal documentation listing of annex to the Mail Clients of mobile phone;

After step 105, Mail Clients receive Email, can directly open and watch internal documentation listing, and the internal file of selecting to download at Mail Clients according to the needs of oneself identifies;

Step 106, Mail Clients identify the mail server that sends to network side with the internal file of choosing, and corresponding internal file is downloaded in request;

Step 107, mail server decompress the identification document of choosing by decompression module, and the identification document of choosing is sent to the mobile phone Mail Clients, and the user can directly open this identification document.

Present embodiment is operated at the annex of compressed format, has avoided whole compressed file is downloaded to the Mail Clients of mobile phone, so neither need take the too much memory space and the network bandwidth, and has reduced mobile phone in the requirement of handling the compressed file ability.

Figure 2 shows that the handling process of another specific embodiment of the present invention, present embodiment is that the user receives the Email that attaches with the annex of paging mode displaying contents (for example ppt, xls, pdf etc.) with mobile phone, and it carries out following steps:

Step 201, mobile phone Mail Clients send request to the mail server of network side, and request receives Email, the subsidiary annex with the paging mode displaying contents of this mail;
