Quality of service control in multiple hop wireless communication environments

摘要

A wireless communication access path exists between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations directly or through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add information bearing on an identified QoS associated with the PDU to the PDUs before they are delivered to the downstream egress station(s) or intermediate relay station(s). The information may be used by the downstream stations to schedule the PDUs for further delivery. The information may also be used by the egress station to schedule the PDUs for delivery.

主权项

1. An egress station comprising:
wireless communication circuitry; and a control system associated with the wireless communication circuitry and configured to:
receive a plurality of packet data units (PDUs) associated with at least one service flow via at least one tunnel established with an ingress station along a wireless communication access path in which the egress station resides in a wireless communication environment; andfor each PDU of the plurality of PDUs:
receive, from the ingress station, with the PDU, information bearing on a quality of service (QoS) class for the PDU, the information determined by the ingress station based on the QoS class identified for the PDU by the ingress station; andprioritize delivery of packets to be transmitted to at least one user terminal, based on the received information.
