eduling requirements if the procedures are executed successfully. The complete specification of the service flow is included in the AAI_DSA-RSP message, if it includes an expanded service class name; Convergence Sub-layer Parameter Encodings specify the service flow CS-specific parameters if the transaction is successful. In response to an AAI_DSA-REQ message containing SCID, the SCID may be included in the AAI_DSA-RSP message to accept the base station or mobile station's request. If the AAI_DSA-RSP message does not include SCID, the MS would assume that the request has been denied. The base station's AAI_DSA-RSP messages for service flows that are successfully added contain an FID for the transport connection, as well as the target SCID for the service flow. If the corresponding AAI_DSA- REQ message uses the service class name to request service addition, the AAI_DSA-RSP message will contain the QoS parameter set associated with the service class name. If the service class name is used in conjunction with other QoS parameters in the AAI_DSA-REQ message, the BS accepts or rejects the AAI_DSA-REQ message using the QoS parameters in the AAI_DSA-REQ message. If these service flow encodings conflict with the service class attributes, the BS uses the AAI_DSA-REQ message values as override for those of the service class. If mobile station's AAI_DSA-RSP with successful status is sent and Service Flow Parameters are included, the only Service Flow Parameters that may be included are ARQ parameters for ARQ-enabled connections. An AAI_DSA-ACK message is generated in response to an AAI_DSA-RSP message. An MS or BS generates the AAI_DSA-ACK message containing the following parameters: 6.8 Connection and session management Control Message Type (i.e., type of AAI_DSA-ACK message); Confirmation Code for the corresponding AAI_DSA-RSP message. Dynamic Service Change: A set of MAC management messages for changing the parameters of an existing service flow The MS or the BS generates the AAI_DSC-REQ message including the following
