A signaling regimen between a mobile station MS, a radio node RN, and a
packet data switching node PDSN enables a quality parameter to be applied
to packets moving between a mobile and a CDMA2000 network. The MS creates
a new flow for packets of a certain data type and sends a related quality
parameter for that flow to the BS. The BS determines whether an existing
or new service instance will carry the new flow, and obtains
authorization for the service instance to meet the quality parameter from
the PDSN. The BS or PDSN builds a map between flow and a policy that
ensures the quality is met, and the map is used to place different
packets into the appropriate flow and service instance. Policies and
enforcement may differ on uplink and downlink.
