Service flow with robust header compression (ROHC) in a WiMAX wireless network

摘要

A robust header compression (ROHC) controller provides for service flow processing of a ROHC channel in a WiMAX wireless communication system. The ROHC controller controls the negotiations of the MS ROHC capabilities during its registration and the negotiations of the ROHC channel parameters during ROHC enabled service flow setup; the MS ROHC capabilities including ROHC compression and decompression capabilities and ROHC channel and feedback strategies; the channel parameter negotiation covers the ROHC profile set and feedback channel information in addition to the 16e/12D standard. The ROHC controller receives a service flow request for a ROHC enabled service flow, wherein the request includes a QoS profile.

1. A method comprising:
registering a wireless mobile station with a WiMAX base transceiver station, wherein registration includes negotiating robust header compression (ROHC) capabilities; and receiving a service flow request for a ROHC enabled service flow, wherein the request includes a Quality of Service (QOS) service profile that is indicative of a priority and contents of a payload conveyed on a desired ROHC channel; wherein in response to a determination that the desired ROHC channel is an aggregated airlink service flow channel:
retrieving an existing desired ROHC channel in response to a determination that the ROHC channel exists based upon the QoS service profile;performing a dynamic service change (DSC) to negotiate parameters of the existing desired ROHC channel; andtransmitting the service flow via the existing desired ROHC service flow including the modified ROHC channel parameters.
