End-to-End UMTS Network Performance Modeling
01 January 2002
User-perceived application-level performance is key to the adoption and success of UMTS services and infrastructure. To predict this performance in advance, a detailed end-to-end simulation model of a UMTS network was built to include application traffic characteristics, network architecture, network element details, and protocol features. The model has been used to assess architectural alternatives, identify system bottlenecks, and validate performance requirements. The main conclusion is that end-to-end application-level performance must be designed in at all phases of the development process.
