User Behavior Analysis Based on Gn Interface of GPRS Network
The General Packet Radio Service (GPRS) has become a standard to extend the services provided by the Global System for Mobile Communications (GSM). Through the introduction of packet switching technology, GPRS supports the use of packet data transmission, allowing a more efficient usage of the radio resources with a consequent improvement in the quality of service of subscribers. This paper presents some observations of the real operational GPRS network in a certain city by analyzing the characteristics of the data which was captured by monitoring system deployed in the Gn interface of GPRS core network. The distributions of the activated users and on-offline users were analyzed in this paper, as well as the online duration characteristic of mobile users. At last, the distribution of users and sessions was discussed, and finally some valuable conclusions were concluded for the mobile network operators.
