Method for correcting source address

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...

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, SCCP only needs to select a route according to the destination address, and does not process the source address. The current new requirement is that the telecommunications networking and addressing methods between network element devices are flexible and diverse, and SCCP is required to process the source address

Obviously, existing technology cannot adapt to current new needs
