Method for transmitting safe point-to-point short message facing to connectionless

Abstract

The invention discloses a transmission method applied to connectionless and safe point to point short messages and the method comprises the following steps: the encoding and decoding of the short messages are carried out at the encoding and decoding interface of the short messages by utilizing the encoding and decoding minimum unit; a densification treatment is carried out for the short messages by utilizing the asymmetric secret key encryption mode; after receiving the encrypted short messages, an application layer processes the encrypted short messages; the processed short messages are sentby the user data message protocol communication interface. By the invention, a connectionless transmission protocol is utilized, namely, the user data message protocol. A plurality of connections do not need to be kept between each external short message entity and access short message center, thereby saving the link maintenance overhead.

Description

technical field [0001] The present invention relates to the alternative application field of Short Message Peer to Peer (SMPP, Short Message Peer to Peer) protocol, in particular to a connectionless secure point-to-point short message transmission method. Background technique [0002] The short message point-to-point protocol is widely adopted by domestic and foreign short message industries, and is a point-to-point short message application protocol for an external short message entity (ESME, External Short Message Entry) to access a short message center. The short message point-to-point protocol is an application layer protocol that can be built on various network architectures such as TCP / IP and X.25. Since the short message point-to-point protocol is a long-connection protocol, the transport layer needs to maintain the connection state for a long time, so the realization of the short message point-to-point protocol currently mostly uses the TCP protocol as the transport ...

AI Technical Summary

Problems solved by technology

[0004] The short message point-to-point protocol conducts plaintext user name and password authentication on external short message entities, and transmits short message content in plain text, which cannot provide security and confidentiality for point-to-point short message services

In order to provide security and confidentiality for the point-to-point short message service based on the short message point-to-point protocol, a dedicated line network must be set up between the external short message entity and the access short message center, which increases the number of mobile network operators and service providers. Cost and complexity of inter-provider interconnection
