  • Patent number: 7599321
    Abstract: An uplink access method in a mobile subscriber station of a broadband wireless access communication system prioritizes uplink bandwidth allocation according to QoS types of requested service. A scheduling priority is assigned to each type of service flow to guarantee the highest data rate for the high QoS service flows, and then the uplink data grants are scheduled based on this assigned priority. By assigning a priority to each connection based on the service type flow, the higher data rate connections will always have the opportunity to transmit uplink data to fulfill the high data rate QoS requirement, and fragmentation will occur only on the last lowest priority Connection ID (CID) based on the size of the last remaining data grant. The uplink access method further prevents the high priority service from stealing bandwidth from data grants intended for lower priority services by identifying when the data grant is mismatched from the amount requested by the lower level services.

  • Patent number: 7496364
    Abstract: A method for implementing a Media Independent Handover (MIH) service between one or more of a heterogeneous and a non-heterogeneous network comprises providing an MIH beacon from one or more of a network (Net) or a mobile node (MN); acknowledging a receipt of the MIH beacon by another of the network (Net) or the mobile node; and facilitating handover (HO) services in response to an acknowledged receipt, and further in response to an MIH beacon message subsequently provided from one or more of the network (Net) or the mobile node. In one embodiment, the MIH beacon comprises at least an MIH-Capability (MIHC) flag, the MIHC flag having one of a first state or a second state.
