Mobile QQ air interface occupying period calculation method based on dot per inch (DPI) and through conservation of amount of information in general packet radio service (GPRS) environment

Abstract

A mobile QQ air interface occupying period calculation method based on dot per inch (DPI) and through conservation of the amount of information in a general packet radio service (GPRS) environment is realized by adding a novel entity between a gateway GPRS support node (GGSN) and a service GPRS supporting node (SGSN) on existing network architecture. Two traditional methods, namely carrying out a drive test (DT) in an air interface and querying base station equipment (both the methods have drawbacks), can be used for acquiring information about air interface resources occupied by a mobile internet user. Currently, most operators build mobile core network DPI systems already; under the premise that no DT instrument is used or a base station resource query function is opened, with the aid of the core network DPI systems built by the operators already, by utilizing acquired application information amount of all core networks, through the DPI technology, with the aid of conservation law of the amount of information, a system can calculate the amount of information carried by the air interface; and then based on a standard rate of GPRS timeslots, the system can calculate air interface resources needed for transmitting the amount of information. Through the calculation method, GPRS air interface resource occupying conditions can be simply, conveniently and quickly calculated so that building cost of an air interface resource monitoring system can be significantly reduced.

Description

technical field [0001] The invention describes a simple and fast calculation method for obtaining the occupation time of air interface resources by mobile QQ under the GPRS environment through DPI technology and the method of applying the law of conservation of information. Under the premise of not using any drive test instrument or opening the resource query function of the base station, this method only uses DPI technology and the law of conservation of application information volume, that is, the application information volume on the air interface side is the same as the application information volume on the core network side. Calculate the amount of information carried by the air interface side based on the amount of application information collected by the core network, and then calculate the air interface resource duration used to transmit the amount of information based on the standard rate of the GPRS time slot. This method is applicable to all scenarios in GRPS networ...

Problems solved by technology

On the one hand, this method can only obtain partial information through drive test sampling; on the other hand, it requires a large number of testers to work outdoors, which is time-consuming and labor-intensive. More importantly, it cannot obtain the air interface resources consumed by specific applications such as mobile QQ.

The second traditional method is to query the base station equipment to obtain air interface resource occupancy information, but this method is only suitable for specific situations, because the load on the base station side is too heavy to withstand a large number of query operations, and this method cannot obtain mobile information. Air interface resource consumption of specific applications such as QQ
