Abstract

Mobile packet services are penetrating mobile markets rapidly. The mobile industry relies heavily on data services to replace traditional voice services. Designing a reliable packet service network is critical to the mobile operators’ ability to maintain their core competence in a data service market. The current literature provides many practical tools and theoretical methods to design, plan and dimension Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) radio networks but overlooks the algorithms of network plan and dimensioning for the core networks. This paper introduces the algorithms to dimension the throughput for packet switched domain of a UMTS network. The analysis is based on the traffic and data throughput generated and absorbed in the interfaces of network entities in UMTS PS network. A case study is provided to verify the algorithms created for UMTS PS network. This paper provides UMTS PS network operators an optimum network size and network structure to deliver an optimum quality of service for users.

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.
