PCU traffic monitoring method and system

Abstract

The invention provides a PCU traffic monitoring method and system. The method comprises the following steps: a data packet transmitted through a GB interface are acquired, and the IP address information of the data packet is analyzed; accumulated statistics is performed on the traffic of the data packet corresponding to each IP address information in the current period; and when the traffic of the data packet corresponding to one of the IP address information is judged to be lowered than the historical period and the lowering range exceeds a first preset value or the traffic of the data packet corresponding to one of the IP address information in the current period is less than a second preset value, a RPP single board of a PCU corresponding to the one of the IP address information is determined to be failed, and the failed RPP single board is determined. According to the invention, by calculating the traffic generated by the IP address of the PCU of each BSC with a fixed period, the traffic accounting of each RPP single board under small time granularity can be realized, and hidden failures of the corresponding single board can be found timely and the software hidden failure of the RPP can be detected.

Description

technical field [0001] The invention relates to the technical field of network connection, in particular to a method and system for monitoring PCU flow. Background technique [0002] With the continuous promotion of various mobile data services and the increasing user penetration rate of GPRS / EDGE (Enhanced Data Rate for GSM Evolution, that is, enhanced data rate GSM evolution technology) mobile phone terminals, mobile data services have developed rapidly , and its growth rate is much higher than that of the voice business. As a functional module for processing data services, PCU (packet control unit) is placed in the BSC and plays the role of GPRS packet data wireless resource management. PCU includes two parts: software and hardware: it is composed of central software and hardware equipment including regional processor RPP / GARP. A PCU can contain 1-64 RPP / GARP boards. [0003] The role played by the PCU is very important, and its RPP single board often has software fail...

AI Technical Summary

Problems solved by technology

The current network situation is that each PCU contains a large number of RPP boards. As far as the BSC in Guangzhou is concerned, there are an average of 40 RPP boards in each PCU of the BSC. It takes 1min-5min to check each board and poll a BSC. The PCU takes more than 40 minutes. Therefore, it is impossible to realize the real-time monitoring of traffic through the command query method.
