Efficient radio resource management in wireless network systems is highly required since the numbers of users as well as the bandwidth requirements per user are growing excessively.
In this paper, two concepts for targeting this capacity challenge are elaborated:
· Multi-standard radio resource management (MxRRM) and
· Location based radio resource management.
By MxRRM we understand the traffic management and radio resource management in scenarios where more than one wireless network provides coverage, like GSM, GSM/GPRS, UMTS, Bluetooth, and/or W-LAN.
If a mobile supports several radio access technologies the question arises which one should be used for a particular communication. To answer this question first it has to be investigated which systems are available. Secondly the decision has to be made which one of these to use based on service, capacity and current load.
For optimized decisions in such an environment, meaning maximum capacity, best QoS (Quality of Service), and minimum energy consumption of the mobile station, utilizing the position of the mobile station is discussed and showing promising results.
