Important:
If the EV-DO Rev A PDSN License is not available or if the number of Rev A sessions exceeds the
license limits, the Rev A calls are downgraded to Rev 0 calls. If the profile ID does not match, the flow will be
downgraded to best effort.
downgraded to best effort.
In an update scenario, the updates may be triggered by one of the following:
TFT validation failure—The MN sent a TFT for a flow/profile id that violates the configured policy for the
flow/profile-id.
Traffic Violation: The MN is using the wrong link flow to send reverse data.
Operator triggered: The Operator triggered an update through the CLI.
Traffic Policing: Traffic policing triggered an update.
The following call flow describes a successful flow setup with QoS update from PDSN.

1. The Main A11 registration setup includes the following actions:
•
The High Rate Packet Data (HRPD) connection is established over the radio link between the MN and the PCF.
•
The PCF recognizes that no A10 connection associated with the MN is available and selects a PDSN. The PCF
sends an A11-Registration Request message to the PDSN. The PCF also includes the Main Service Option for
HRPD (SO59) in the message to indicate to the PDSN that this is the main service connection. The PCF includes
the Connection Setup Airlink record in this message. If the main connection is active, and the PCF has received
enough information about the flow, the PCF also includes the Active-Start airlink record for the main A10
connection.

The A11-Registration Request message is validated and the PDSN accepts the connection by returning an A11-
Registration Reply message and acceptance. The A10 connection binding information at the PDSN is updated to
point to the PCF.
