Performance analysis for cellular systems supporting heterogeneous services

An analytical model is proposed to study the grade-of-service (GOS) performance for cellular communication systems supporting heterogeneous services, where GOS includes handoff connection dropping probability (HCDP), new connection blocking probability (NCBP) and system resource utilization. In the analytical model, a higher priority is given to a handoff connection than a new connection by resource reservation. The amount of the reserved resource depends on the current traffic load, and can be adjusted to achieve different HCDP. Numerical results are given to demonstrate the GOS performance.
