Accuracy detection method of data service traffic accounting for gprs/umts network

Abstract

The invention discloses a detection method for the charging accuracy of the data service flow of a GPRS (General Packet Radio Service) / UMTS (Universal Mobile Telecommunications System) network, comprising the following steps of: (1) firstly opening a mirror port of a Gn interface of a GGSN (Gateway GPRS Support Node) on a switch on which an SGSN (Service GPRS Supporting Node) and a GGSN are connected mutually, and connecting a detecting instrument to the mirror port; (2) acquiring data passing through the mirror port and storing the data on a hard disk by the detecting instrument, and meanwhile, generating an instrument ticket; (3) comparing the instrument ticket, a G-CDR (Call Detail Record) ticket and a subscriber ticket under the condition that enough samples are acquired, wherein the G-CDR ticket and the subscriber ticket are provided by an operating enterprise; and (4) counting the number of excess tickets, absent tickets and mistaken tickets, and generating a detection report of the charging accuracy according to standard requirements. Compared with the prior art, the invention has high accuracy and sufficient sample number, can cover multiple conditions of terminals and networks, and the like.

Description

technical field [0001] The invention relates to a method for detecting the accuracy of flow charging of a mobile data communication network, in particular to a method capable of detecting the accuracy of charging of data service flow of a GPRS / UMTS network, and belongs to the technical field of communication testing. Background technique [0002] In recent years, the GSM network has been gradually upgraded to a GPRS (General Packet Radio Service, General Packet Radio Service) network, and further developed into a UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) network. With the continuous development of the economy, mobile communication users are increasingly dissatisfied with voice services, and various data services continue to emerge. Especially in early 2009, my country officially issued 3G licenses. The 3G network has laid a network foundation for the rapid development of mobile data services. [0003] Due to the limited w...

Problems solved by technology

There are many shortcomings in this detection method: firstly, due to the problems of packet loss on the wireless side and packet unpacking and combination of network equipment, the traffic of the network terminal and the traffic of the billing point must be different; secondly, the network used for detection The types of terminals are limited, and network terminals can only simulate a small number of online processes; thirdly, the statistical methods of terminal traffic statistics software are various, without uniform standard constraints, and the number of samples and the quality of samples cannot be guaranteed

The disadvantage of this method is that there are many related instruments, and it needs to connect to the GPRS network

In general, there is still a lack of scientific and effective mature detection schemes at home and abroad for the detection of billing accuracy of mobile data traffic
