parameters: Control Message Type (i.e., type of AAI_DSC-REQ message); Service Flow Parameters specify the service flow's new traffic characteristics and scheduling requirements or the admitted and active QoS parameter sets currently in use by the service flow. If the dynamic service flow change message is successful and it contains service flow parameters, but does not contain replacement sets for both admitted and active QoS parameter sets, the omitted set is set to null. The service flow parameters include the FID. The SCID may be included in the AAI_DSC-REQ message to change sleep cycle setting. An AAI_DSC-REQ message does not carry parameters for more than one service flow. The AAI_DSC- RSP message is generated in response to the AAI_DSC-REQ message inclusive of the following parameters: Control Message Type (i.e., type of AAI_DSC-RSP message); Confirmation Code for the corresponding AAI_DSC-REQ message; Service Flow Parameters specify the service flow's traffic characteristics and scheduling requirements if the transaction is successful. Complete specification of the service flow is included in the AAI_DSC-RSP, if a service flow parameter set contained a service class name and an admitted QoS parameter set. The AAI_DSC-RSP message further includes the QoS parameter set corresponding to the service class name. If specific QoS parameters were also included in the service flow request, these QoS parameters are included in the AAI_DSC-RSP message instead of any QoS parameters of the same type of the service class name. Convergence Sub-layer Parameter Encodings specify the service flow's CS-specific parameters, if the procedures are successfully executed. In response to an AAI_DSC-REQ message which contains SCID, the SCID may be included in an AAI_DSC-RSP message to accept the base station or mobile station's request. If the AAI_DSC-RSP message does not include SCID, the MS would assume that its request has failed. An AAI_DSC-ACK message is generated in response to a received AAI_DSC-RSP message. The MS or the BS
