Automatic recognizing method for Iub interface public transmission channel kinds

Abstract

The present invention discloses transmission channel type and ATM transmission bearing automatic identification method in third generation mobile communication wireless access network Iub interface, referring to third generation mobile communication system (3G) signalling testing technology. The present invention utilizes each public transmission channel data frame length aggregative difference, extracting ATM connection data frame length in public channel and recording each ATM connection transmission bearing parameter VPI / VCI / CID; then comparing extracted data frame length with data in established data frame length congregation, judging Iub Interface public transmission channel type. The present invented method can quickly accurately judge out one Node B supported all public transmission channels ATM bearing parameter, without restarting node equipment and unaffecting network operation.

Description

technical field [0001] The invention relates to the technical field of the third generation (3G: the 3rd Generation) mobile communication, especially the signaling test technology of the 3G mobile communication network. Background technique [0002] The third-generation mobile communication network is composed of wireless access network and core network, and its signaling test and protocol analysis play an important role in network construction and stable operation. They mainly complete the signaling monitoring, business statistics, network optimization, call tracking and other functions of the 3G network. Among them, the signaling monitoring of the wireless access network is the core task of the signaling test. Among them, Node B (Node B) and wireless network The monitoring of the Iub interface between controllers (RNC, RadioNetwork Controller) is the most complicated. attached figure 1 It is the protocol stack structure of the Iub interface, which is divided into two fun...

Problems solved by technology

At present, there are two ways to obtain their ATM parameters: one is to restart the Node B, trigger the re-establishment process of the public transmission channel, and capture their bearer parameters, which will cause a large number of service interruptions, and it is obviously necessary for the normal operation of the network not possible

The second method is to manually configure, that is, to find the transmission bearer parameters corresponding to each transmission channel from the ATM bearer allocation records in the network management database. This method is inefficient and depends on the implementation methods of different manufacturers.
