Implementing cascade short message transmission method in short message system by segmenting affirmation mechanism

Abstract

The invention discloses a method that a subsection validation mechanism realizes concatenation short message transmission, comprising: a short message sending terminal divides a primed concatenation short message into a plurality of subsections; the message sending terminal sends a first section to a short message receiving terminal via a short message central terminal, and waits for response; after receiving a first subsection message, the short message central terminal immediately returns the response to the short message sending terminal; after the short message sending terminal receives the successful response, the short message receiving terminal returns a first subsection return receipt to the short message sending terminal, and displays content of the subsection and information of the subsection; after the short message receiving terminal receives the successful return receipt of the first subsection, the following subsections are continuously sent via repeating above steps. The method of the invention adopts a subsection message sending waiting validation mechanism and a method of filling characters in the tail-end of the subsection, so as to effectively avoid the uncommon conditions that the subsection of the concatenation short message is lost, dislocated, etc. and improve practicability, flexibility and reliability of concatenation short message services.

Description

technical field [0001] The invention relates to a method for realizing short message transmission, in particular to a method for realizing cascaded short message transmission. Background technique [0002] In the prior art, the Global System for Mobile Communications 0340 (GSM0340) protocol is a technical implementation standard for the point-to-point short message service of the GSM network, which describes a cascaded short message service. The maximum length of an ordinary short message is 140 bytes, which can accommodate 140 8-bit characters or binary data, 70 unicode characters, or 160 7-bit characters. However, in the actual application of the short message service, the content length of the short message easily exceeds this limit. In order to be able to send a short message that exceeds the limit of the content length of a single short message, the GSM0340 protocol stipulates the mechanism of realizing super long short messages by cascading multiple segmented short me...

AI Technical Summary

Problems solved by technology

[0006] In the prior art, the cascaded short message cannot guarantee the reliability of its own transmission, and each network element in the GSM network does not have a unified processing method for the transmission reliability of the cascaded message, which can easily lead to the loss and dislocation of the cascaded short message segment
