2. 2 Introduction “Service Specific BR without STID Header” is sent through dedicated UL resource assigned to the AMS, which needs to change the scheduling parameters of its service flow –That is, QoS parameter switching is done via this specific BR header When the QoS parameter set is alternated, so as the traffic characteristics The goal of sleep mode is to mimic the traffic characteristic of a service flow –In 802.16m, multiple sets sleep mode configuration are configured with SCIDs Motivation: is it possible to combine the QoS parameter set updating and SCID updating in a single procedure? –The sleep mode configuration could be updated accordingly Benefit: –No MOB_SLP-REQ/RSP are required

3. 3 Observation There are 14 reserved bits in service specific BR without STID header

4. 4 Example VoIP with silence suppression –Primary QoS parameter set is for active talking –Secondary QoS parameter set is for silence period SCID1 is applied SCID2 is applied

5. 5 MSC of the Proposed Method (a) Current MSC flow (b) Proposed MSC flow

BR Type1Indicates whether the requested bandwidth is incremental or aggregate. 0: incremental 1: aggregate BR Size19Bandwidth request size in bytes.
