Performance investigation of multi standard radio resource management for packet switched services

The plurality of currently available mobile communication systems is increasing. Now, after 2G and 2.5G systems, like GSM/GPRS, have achieved a coverage of close to 100% in many parts of the world, 3G systems, like WCDMA/UMTS, enter the market. In addition to these cellular systems, systems based on wireless LAN technologies are also experiencing a strong growth. With these systems being independent to a large extent, the utilization of their resources is suboptimal. To combine the resources of the formerly separated systems, the article describes an approach for applying "multi standard radio resource management" for packet switched traffic. To achieve better utilization of cell resources, in order to improve the system performance in terms of user data rate and system capacity, three strategies are presented and evaluated based on simulation results. The results show that a significant improvement of overall system performance can be achieved.
