Embodiment Construction

[0041] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0042] see figure 2 As shown, the DUPU message transmission method provided by the embodiment of the present invention mainly includes the following steps:

[0043] Step 201: the first signaling node where the user is partially unavailable returns a DUPU message to the second signaling node, and carries the source signaling point code that triggered the DUPU message;

[0044] Step 202: After receiving the DUPU message, the second signaling node forwards the received DUPU message according to the origin signaling point code that triggers the DUPU message carried therein.

[0045] Wherein, step 202 specifically includes: the second signaling node judges whether the origin signaling point code that triggers the DUPU message carried in the received DUPU message ...

Abstract

The present invention provides a transmission method of destination user part unusable (DUPU) message which includes: first signaling node of generating user part unusable returns DUPU message back to second signaling node, and carries the origin signaling code of DUPU message; after receiving DUPU message, second signaling node transmits the received DUPU message according to carrying origin signaling code of the DUPU message. In addition, the present invention also provides a DUPU transmission system and a signaling node. The present invention can realize right transmitting of DUPU message, alleviating transmitting burden, decreasing waste of transmitting resource.

Description

technical field [0001] The invention relates to signaling network management technology in a communication system, in particular to a transmission method, a system and a signaling node of a destination user partially unavailable message. Background technique [0002] The signaling transmission (SIGTRAN) protocol stack is a PSTN signaling and IP interworking specification formulated by the SIGTRAN working group, which supports the transmission of traditional circuit switched network (SCN) signaling through the IP network. The protocol stack supports the interlayer standard primitive interface defined in the layered model of the SCN signaling protocol, so as to ensure that the existing SCN signaling application can be used without modification. At the same time, the standard IP transmission protocol is used as the bottom layer of the transmission. Its own functions meet the special transmission requirements of SCN signaling. [0003] The main functions of the SIGTRAN protocol...
