Method and system for monitoring PCU traffic

Abstract

The present invention provides a method and system for PCU flow monitoring, the method comprising: collecting data packets transmitted through the GB interface, and analyzing the IP address information of the data packets; accumulating and counting the data packets corresponding to each IP address information in the current cycle When it is judged that the flow of data packets corresponding to one of the IP address information is lower than the flow of the historical period, and the decline rate exceeds the first preset value, or the data packet corresponding to one of the IP address information in the current cycle When the flow rate is less than the second preset value, it is determined that the RPP single board of the PCU corresponding to the one of the IP address information is faulty, and the faulty RPP single board is determined. The present invention calculates the traffic generated by the IP addresses of the PCUs of each BSC in a fixed period, and can realize the traffic accounting of each RPP single board at a relatively small time granularity, and can detect hidden faults of the corresponding single board in time Software hidden failure of RPP.

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) mobile phone terminals, mobile data services have developed rapidly. Its growth rate is much higher than that of 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 failures. Once such a situation occurs, the data service of the cel...

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.
