Method for restarting and restoring work of charging gateway

Abstract

The invention relates to a method for restarting and restoring work of a charging gateway (CG), which comprises the following steps : after failing and being restarted, the CG judges different conditions when the fault occurs, and respectively executing corresponding operation according to the information stored at a working area before the fault occurs; and under the condition that the work can not restored by a fault-tolerant mechanism between SGSN or GGSN, firstly, reasonably selecting the retrospective analyses time starting from the time point when the fault occurs, then carrying out retrospective comparative analysis on an original ticket and a final ticket locally stored by the CG, reconstructing an original ticket Hash table after discovering the uncombined original ticket and the final ticket and deleting the combined original ticket, and restoring normal work of the CG. The method comprises five operation steps of restarting the fault, judging the type of the fault, analyzing part of the ticket, reconstructing the Hash table and restoring the normal operation. The method leads the CG to be capable of completing restarting and restoring the previous work when any fault occurs, improves work reliability and the accuracy of the charging ticket, and ensures that the work performance of the whole charging gateway is not influenced obviously.

Description

technical field [0001] The invention relates to a processing technology for billing bills of packet data services in a mobile communication system, to be more precise, relates to a method for restarting and resuming work of a charging gateway CG, and belongs to the technical field of mobile communication charging. Background technique [0002] Charging Gateway (CG) is a basic network element of TD-SCDMA and GPRS / WCDMA mobile communication network. Its function is to realize the collection of charging data in the data domain of mobile communication network. location such as figure 1 shown. For the telecom billing gateway, the design requirements for the stability and disaster tolerance of the network element are very high, and a dual-machine redundancy backup mechanism is usually used to improve the reliability of the device. Nevertheless, telecom operators have also put forward corresponding design requirements for the disaster recovery of a single server. In the design s...

Problems solved by technology

[0008] However, the above-mentioned mechanism does not take into account all the circumstances of the failure: if a failure occurs during the process of merging the original bills, that is, after the CG replies to the SGSN or GGSN and before the final bill is saved, the SGSN or GGSN has discarded the original bills, and CG needs to re-establish the merging process based on the saved original bills, and then restore to the working state before the failure and continue to receive the original bills from SGSN or GGSN

However, the existing technical specifications do not clearly provide the corresponding processing method for CG to deal with this time period, resulting in a blind spot in business processing. This problem naturally becomes a problem that CG must solve when it realizes normal work; otherwise, once such a situation occurs , will result in the loss of some bills
