Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] Figure 1A is a schematic structural diagram of the email transmission system provided by the embodiment of the present invention, see Figure 1A , the email transmission system includes a client 10, a server 20, a client mail service agent 30 and a server mail service agent 40, and the client 10, the client mail service agent 30, the server mail service agent 40 and the server 20 are connected in sequence.

[0052] Wherein, the client mail service agent 30 is set between the client 10 and the server 20, and is relatively close to the client 10, and the two can be connected by wire. The server mail service agent 40 is set between the client 10 and the server 20, and is relatively close to the server 20, and the two can be connect...

Abstract

The invention discloses an email transmission method and system, belonging to the technical field of wireless communication. The method includes: receiving the first email sent by the client through the SMTP protocol, and recording the SMTP interaction information; respectively encapsulating the email and the SMTP interaction information into the first email data packet and the authentication data packet; determining the frame length, using the frame The length of the authentication data packet is divided into frames to obtain the first data frame, and the first data frame is sent to the server; the second data frame sent by the server is received, and the authentication success data packet is obtained according to the combination of the second data frame; Framing the first mail data packet to obtain a third data frame, and sending the third data frame to the server; receiving the fourth data frame sent by the server, combining the fourth data frame to obtain the second mail data packet, Decapsulating the second mail data packet to obtain a second email.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an email transmission method and system. Background technique [0002] E-mail is the most important application service provided on the wireless channel, regardless of short wave, ultra short wave, or satellite channel, etc., will provide corresponding e-mail applications. Different wireless channels have different communication characteristics, but most of them have unstable quality, serious interference, and limited bandwidth. If the commercial e-mail systems widely used in wired networks are directly applied to all wireless channels, these systems will be inefficient in most cases, and even many times these systems use TCP / IP-based (English: Transmission Control Protocol / Internet Protocol, Chinese: Transmission Control Protocol / Internet Internet Protocol) SMTP / POP3 (English: Simple Mail Transfer Protocol / Post Office Protocol-Version 3, Chinese: Simple Mail Tra...
