Performance Analysis of AAL2 Switching/Multiplexing in the Iub Interface in UMTS Network
01 January 2003
User-perceived application-level performance is very important in the adoption and success of UMTS (Universal Mobile Telecommunication System) services and infrastructure. To predict this performance, a detailed end-to-end UMTS network performance simulator was developed. This simulator allows the modeling of application traffic characteristics, network architecture, network alternatives, identify system bottlenecks, and validate performance requirements. This paper illustrates the use of this simulator to study the AAL2 switching effort across the interface Iub between a base station and a RNC.
