ABSTRACT:
Method and system to support fast hand-over of mobile subscriber stations in broadband wireless networks. In connection with a hand-over process, a determination is made to which target base station (BS) an air interface for a mobile subscriber station (MSS) is to be handed-over. Various service requirements are requested by the MSS, including a Quality of Service (QoS) level. Based on feedback from potential target BSs, a target BS for hand-over is selected. Current connection context data corresponding to current service flows provided by a serving BS is passed to the target BS to pre-provision service such that a minimal amount of re-entry messaging is required. In one embodiment, a Management Information Base (MIB) instance is maintained at each BS in a broadband wireless network. To pre-provision service, applicable connection context data are transferred between MIB instances at the serving and target BS using Simple Network Management Protocol (SNMP) messaging.
