WiMAX DSA REQ vs DSA RSP-Difference between DSA REQ and DSA RSP

This page on DSA REQ and DSA RSP describes WiMAX Dynamic Service Addition used for primary management. It mentions difference between DSA REQ and DSA RSP messages as per as per IEEE 802.16 OFDM MAC fixed wimax specifications.

The wimax compliant Base Station transmits DSA REQ message to the Subscriber Station(SS) to set up connections for pre-provisioned service flows belonging to the SS The SS responds with DSA RSP messages to the BS.

Creation of service flows may be initiated by either Base Station or by SS. Initiated by BS is mandatory requirement while initiation by SS is optional.

Let us understand BS initiated Dynamic Service Flow Creation. DSA REQ from BS contains SFID for either one uplink or one downlink, associated CID, set of QoS parameters. SS responds with DSA-RSP indicating acceptance or rejection.

As mentioned DSA REQ, DSA RSP and DSA ACK are used for this purpose. DSA REQ and DSA RSP messages are same as REG REQ and REG RSP messages respectively.
