An Analysis of Traffic and Throughput for UMTS Packet Core Networks

Literature Review

The current literature provides many practical tools and theoretical methods to design, plan and dimension GSM and UMTS radio networks but overlooks the algorithms of network plan and dimensioning for GPRS (General Packet Radio Service) network, packet switched domain of UMTS network, and IP Multimedia Sub-system (IMS). Also no previous literature provides a unified approach to calculate the throughput or traffic for UMTS packet switched network. Very few studies have been made on the wireless core network planning and dimensioning topics. This can be explained by two facts that both packet switched domain and circuit switched domain in UMTS core network are logically or physically more complicated in structure than radio access network and the internal throughput or traffic may vary by different vendors’ NEs.
