Quality of Service

  • Ramjee Prasad
  • Fernando J. Velez


The interpretation and definition of service quality and its classes is first presented. While there are four classes of service in Fixed WiMAX (unsolicited granted service, real-time polling service, non-real-time polling service and best effort) in Mobile WiMAX there is an extra class: extend real-time polling service. The Quality of Service (QoS) architecture is presented for the point-to-multipoint (PtM) mode. Packets originated at the SS are classified by the connection classifier based on the connection ID (CID) and are forwarded to the appropriate queue for the communication with the BS. The discussion of details on the architecture includes aspects of UL and DL scheduling. QoS provisioning and the object model for service quality are also discussed. Finally, the authorization module is addressed as well as service flow types and creation.
