Description

The present invention claims to be a Chinese patent application filed on January 11, 2011 by the Chinese Patent Office, the application number is 201110004534.8, and the invention is entitled "A Method and Apparatus for Managing Mail of Mobile Terminals". Priority is hereby incorporated by reference in its entirety. Technical field

The present invention relates to the field of communications, and in particular, to a method and apparatus for managing mail of a mobile terminal. Background technique

At present, the use of mailboxes on PCs (Personal Computers), mobile terminals (such as mobile phones), and other devices is becoming more and more widespread. For mobile terminal users, only users need to open mobile terminal mailbox services to implement mail. Transceiver function, mobile terminal mailbox service means that the network server sends the mail sent to the mail server to the user's mobile terminal in real time, and the user can read, reply, forward or compose the email; the current mail server mainly includes the enterprise email server and 139 mailbox server.

At present, the network system structure of the mobile terminal mailbox service is shown in Figure 1. The mail proxy gateway and the mobile terminal pass the CMPOP (China Mobile Post Office Protocol) interface or CMSMTP (China Mobile Simple Mail Transfer Protocol, China). Mobile Simple Mail Transfer Protocol) interface to complete mail sending and receiving operations; POP3 (Post Office Protocol 3, Post Office Protocol 3) interface, IMAP4 (Internet Message Access Protocol 4, interactive data message access) between mail proxy gateway and mailbox server The fourth version of the protocol) interface or SMTP (Simple Mail Transfer Protocol) interface to complete the sending and receiving of mail; the interface of the mail push gateway and the CBOSS system (ie, the customer operating entity system) is used to open the mailbox service of the mobile terminal; The enterprise mailbox server is connected to the mail push gateway through the enterprise mail proxy gateway, and the 139 mailbox server is connected to the mail push gateway through the public mail proxy gateway; the mobile terminal connects with the mail push gateway through the inter-provincial gateway to which the mobile terminal belongs, Mobile terminal users can It is a GSM (Global System for Mobile Communications) network, a GPRS (General Packet Radio Service) network, or a 3G network (Time Division-Synchronous Code Division Multiple Access). User in code division multiple access)).

The mobile terminal receives the mail or sends the mail through its mail client. When the mail client of the mobile terminal receives the new mail, the user can be reminded to arrive at the new mail according to the user setting. Compared with the mail client on the PC, the mail client of the mobile terminal is suitable for the mail client version of the mobile terminal operating system, and the protocol between the mobile terminal mail client and the server on the network side is based on the wireless network optimization setting. If you use the POP3 protocol to receive mail, you can use the SMTP protocol to send mail.

Currently, in order to reduce data traffic, for mail with attachments, the mobile terminal mail client only receives the body of the mail when receiving the mail, and the attachment of the mail needs to be downloaded separately by the user according to the demand; when the mail client of the mobile terminal receives the attachment , directly store the attachment to the location specified by the user; if the attachment carried in the email needs to be converted into an attachment of a different format when downloading, for each format, the attachment is converted into an attachment of the format, and the format is converted The attachment is stored to a location specified by the user. With the current mail management method, the following technical problems exist: On the one hand, the mobile terminal mail client directly stores the attachment when receiving the attachment, and the name of the attachment in the email is named by the sender user, and may be local to the mobile terminal. The name of an attached attachment is the same, so there may be a problem of naming duplicates of at least two attachments; on the other hand, when converting multiple formats of one attachment, multiple attachments obtained after conversion of multiple formats A separate storage operation is required for each attachment. The same named attachment may already exist. At this time, when the attachment is received, there may be a problem of duplicated names, the storage process is complicated, and the storage efficiency is low; and, the attachment is performed. The format is still stored under the name of the attachment, so there is still a problem of duplicate naming with other attachments stored by the mobile terminal. Summary of the invention
