A Dimensioning Study for UMTS Core Networks

Literature Review

The current literature provides many practical tools or theoretical methods to design, plan and dimension GSM and UMTS radio networks but overlooks the algorithms for planning and dimensioning of core networks of GSM, UMTS and IMS. No previous literature provides a unified approach to calculate the throughput or traffic of the UMTS core network. Very few studies have addressed the mobile core network planning and dimensioning topic. This is because that the core network in either logical or physical structure is more complicated than the radio access network and the internal throughput or traffic may vary from different vendors’ NEs.
