QoS efficiency for individual user in 3G networks

Abstract

Packet data traffic volume and a packet switch related services climb upward in UMTS (Universal Mobile Telecommunications System) networks. Services provided on a live network became very complex and require different QoS (Quality of Service). 3GPP defines four service types: conversational, interactive, streaming, and background, which can be managed, in terms of quality, to ensure differentiated services for end users. HSPA (High Speed Packet Access) Diff- Serv management provides facilities based on service type and user priority. Different user profiles allow to maintain high level services and to control users in networks based on the load. The goal of this research is to estimate the efficiency of quality management based services for individual user on UMTS network. End user experience is most concerned question of this research. The users attempting background traffic class service are investigated. According to this, three different users (Gold, Silver, Copper) are distinguished, which are formed by combining SPI (Scheduling Priority Indicator) and ARP (Allocation/Retention Priority) parameters related to QoS assurance. Practical part of study is performed on a commercial mobile network. Provided results reflect the user experience and impact for the 3G network.
