IEEE Std 802.16-2001

LOCAL AND METROPOLITAN AREA NETWORKS—PART 16:

6.2.13.7.2 Dynamic service flow creation

Service flows may be created by the Dynamic Service Addition (DSA) process as well as through the Registration process outlined above. The DSA may be initiated by either the SS or the BS and may create one uplink and/or one downlink dynamic service flow(s). A three-way handshake is used to create service flows.

6.2.13.7.2.1 Dynamic service flow creation — SS-initiated

The SS-initiated protocol is illustrated in Figure 65 and described in detail in 6.2.13.8.3.1.

Figure 65—DSA message flow—SS-initiated

A DSA-REQ from an SS contains service flow Reference(s) and QoS Parameter set(s) (marked either for admission-only or for admission and activation).

6.2.13.7.2.2 Dynamic service flow creation—BS-initiated

A DSA-REQ from a BS contains Service Flow Identifier(s) for one uplink and/or one downlink Service flow, possibly their associated CIDs, and set(s) of active or admitted QoS Parameters. The protocol is illustrated in Figure 66 and is described in detail in 6.2.13.8.3.2.
