In next generation wireless networks such as a Mobile WiMAX traffic prioritization is used to provide differentiated quality of service (QoS). Unnecessary ping-pong handovers that result from premature reaction to fluctuating radio resources pose a great threat to the QoS of delay sensitive connections such as VoIP which are sensitive to scanning and require heavy handover mechanisms. Traffic-class-specific variables are defined to tolerate unbalance in the radio system in order to avoid making the system slow to react to traffic variations and decreasing system wide resource utilization. By setting thresholds to trigger load balancing gradually in fluctuating environment the delay sensitive connections avoid unnecessary handovers and the delay tolerant connections have a chance to react to the load increase and get higher bandwidth from a less congested BS. A framework for the resolution of static user terminals in the overlapping area within adjacent cells will be described.
