Packet Switch Traffic Analysis in 3g (w-cdma) System

Third Generation (3G) mobile devices and services will transform wireless communications into on-line, real-time connectivity. 3G wireless technology will allow an individual to have immediate access to location-specific services that offer information on demand. 3G wireless systems such as 3G-1X, 1xEV-DO and 1xEV-DV provide support for a variety of high-speed data applications. The success of these services critically relies on the capability to ensure an adequate QoS experience to users at an affordable price. The traffic being transferred within 3G mobile networks will be composed by different information flows with various constraints on the required QoS (bit rate, delays, etc.). In this paper, we give an evaluation of the performance of 3G networks when providing access to voice and data services. In particular, we analyze through simulations a typical scenario where voice and data services affect the packet traffic in 3G system approach. KEYWORDSQoS, WCDMA, UMTS, Packet Traffic.
