Problems solved by technology

If the source address is the addressing of the GT route, and the destination device requires the addressing of the DPC combined with the SSN route, then it must not be able to respond to the reply message
[0016] To sum up, the existing technology is based on the current telecommunication networking mode between network element devices, adopting a single GT routing addressing mode

Embodiment Construction

[0033] The core idea of ​​the present invention is: firstly, the present invention establishes the mapping relationship between the correction key information and the source address correction strategy, and stores it in the database. Here, when the addressing mode encapsulated in the destination address is the addressing of GT routing, the key correction information may be a combination of at least one information of the network element device address of the destination signaling end after GT translation and the destination address information after GT translation. In this way, after SCCP is translated by GT, the combination of at least one information of the network element device address of the translated destination signaling end and the translated destination address information can be used as the key information for correction, and the established mapping relationship in the database can be searched to obtain The corresponding source address correction policy completes the...

Abstract

The invention discloses a source address correcting method comprising following steps that: after receiving a SCCP information, a signaling connection and control part (SCCP) reads the source address and destination address in the SCCP information, and determines and corrects critical information according to the destination address; according to the built mappings hypotaxis between the corrective critical information and the source address corrective strategy, the SCCP obtains the source address corrective strategy mapped to the determined corrective critical information and finishes the correction to the source address. This invention, being capable of adapting to present new demands and aiming to the condition of variable modes of telecommunication networks among meshwork devices and variable addressing modes, makes the SCCP realize the processing and correcting to the source address.

Description

technical field [0001] The invention relates to source address correction technology, in particular to a method for source address correction of a Signaling Connect and Control Part (SCCP, Signaling Connect and Control Part) in the No. 7 signaling system. Background technique [0002] In the existing No. 7 signaling system, SCCP only needs to select the route according to the destination address, and usually does not process the source address, and directly transmits it transparently. For example, if figure 1 as shown, figure 1 It is a schematic diagram of an existing telecommunication network based on the SCCP protocol stack. figure 1 Including source signaling terminal 1, signaling transfer terminal 2, and destination signaling terminal 3. Moreover, the hierarchical structure of the SCCP protocol stack in the source signaling terminal 1 includes the first upper layer application 11, the first SCCP12, the first MTP313, the first MTP214 and the first MTP115; the hierarchi...
