Image quality assessment plays an important role to the 3G network QoE/QoS planners. A great deal of effort has been made in recent years to develop objective image quality metrics that correlate with perceived quality measurement. In this paper, suggestion a method to capture the frame of video phone on DtivyTM A2000+H platform.

The IP Multimedia System (IMS) is a promising solution for converging new technologies with existing networks. The interworking environment and service flexibility that IMS offers to the currently deployed wireless broadband technologies, makes it appealing to users, service developers and network operators. In this paper an analytical model is derived in order to evaluate the signalling cost of mobility management during a vertical handoff.

This paper investigates genetic algorithm (GA) based approach for dynamic OVSF code assignment in WCDMA networks. Different from existing conventional code assignment (CCA) and dynamic code assignment schemes, population is adaptively constructed according to existing traffic density in the OVSF code-tree. In order to improve the ability of the GA, we employ so-called ‘‘ dominance & diploidy’’ structure to adapt to changing traffic conditions.

GPRS Tunnel Protocol(GTP), which is one of the key protocols in the core network, is quite vulnerable to attacks in the flat, full IP environment. Therefore solving such problem properly is very urgent and important for the operation of 3G network. In this paper, a security analysis of GTP is presented, a defense solution for these security threats and an event-based description language are also proposed.
