Abstract
This paper proposes a new approach for a advanced handover protocol that uses the direction of arrival estimation of adaptive antennas in combination with other mobile movement prediction methods and shows the struktur of possible simulationtool in SDL. This paper also discusses the need for combined link level and system level simulations for third generation mobile radio systems and points out a way of implementing them in SDL. The simulation of third generation mobile radio interfaces is a particular challenge on calculation power. Complex systems are needed to support the demand of ATM services and high data rates up to 2 Mbit/s in the UMTS band. The physical influences of mobile radio channels shall be considered within the system level simulation of protocols for mobile radio systems, since channel allocation and handover protocols need physical parameters.
