 with RRM function, as well as a centralized RRM entity that does not reside in the BS and collects and updates radio resource indicators such as choice of target BS, admission or rejection of service flows, etc., from several BSs. The RRM procedures facilitate the following WiMAX network functions: MS admission control and connection admission control, i.e., whether the required radio resources are available at a candidate target BS prior to handover; Service flow admission control, i.e., creation or modification of existing/additional service flows for an existing MS in the network, selection of values for admitted and active QoS parameter sets for service flows; Load balancing by managing and monitoring system load and use of counter-measures to enable the system back to normal loading condition; Handover preparation and control for improvement/maintenance of overall performance indicators (for example, the RRM may assist in system load balancing by facilitating selection of the most suitable BS during a handover). The RRM is composed of two functional entities, i.e., radio resource agent (RRA) and radio resource control (RRC). The radio resource agent is a functional entity that resides in the BS. Each BS includes a radio resource agent. It maintains a database of collected radio resource indicators. An RRA entity is responsible for assisting local radio resource management, as well as communicating to the RRC to collect and measure radio resource indicators from the BS and from a plurality of mobile terminals served by the BS using MAC management procedures as specified by the IEEE 802.16 specifications. It also communicates RRM control information over the air interface to the MS, as defined by the IEEE 802.16 specifications. An example of such RRM control information is a list of neighbor BSs and their parameters. It further performs signaling with RRC for radio resource management functions, as well as controlling the radio resources of the serving BS, based on the local measurements and reports received
