Abstract
The invention provides 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 code-division multiple access (CDMA) 2000 environment. The mobile QQ air interface occupying period calculation method based on the DPI and through the conservation of the amount of the information in the CDMA 2000 environment can be realized by adding a novel entity between a radio access network (RAN) interface and a packet data service node (PDSN) interface on existing network architecture. A system can acquire information about air interface resources occupied by a mobile internet user through two traditional methods, namely by carrying out a drive test (DT) in an air interface and by querying base station equipment (both the methods have drawbacks). 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 the acquired application information amount of all core networks, through the DPI technology, with the aid of conservation law of the amount of information, the system can calculate the amount of information carried by the air interface; and then based on a standard rate of the CDMA 2000, the system can calculate the air interface code channel resource utilizing period needed for transmitting the amount of information. Through the calculation method, a CDMA 2000 air interface resource occupying period can be simply, conveniently and quickly calculated so that building cost of an air interface resource monitoring system can be significantly reduced.
