Intelligent Traffic Control
Intelligent Traffic Control (ITC) supports customizable policy definitions that enforce and manage service level
agreements for a subscriber profile, thus enabling differentiated levels of services for native and roaming subscribers.

In 3GPP2, service ITC uses a local policy look-up table and permits either static EV-DO Rev 0 or dynamic EV-DO Rev

Important:
ITC includes the class-map, policy-map and policy-group commands. Currently ITC does not include
an external policy server interface.
ITC provides per-subscriber/per-flow traffic policing to control bandwidth and session quotas. Flow-based traffic
policing enables the configuring and enforcing bandwidth limitations on individual subscribers, which can be enforced
on a per-flow basis on the downlink and the uplink directions.

Network Operation Management Functions
This section describes the following features:
A10/A11
Provides a lighter weight PPP network control protocol designed to reduce connection set-up latency for delay sensitive
multimedia services. Also provides a mechanism to allow user devices in an evolved HRPD network to request one or
more PDN connections to an external network.
multimedia services. Also provides a mechanism to allow user devices in an evolved HRPD network to request one or
more PDN connections to an external network.
The HRPD Serving Gateway connects the evolved HRPD access network with the Evolved Packet Core (EPC) as a
trusted non-3GPP access network. In an e-HRPD network the A10'/A11' reference interfaces are functionally equivalent
to the comparable HRPD interfaces. They are used for connection and bearer establishment procedures. In contrast to
the conventional client-based mobility in an HRPD network, mobility management in the e-HRPD application is
network based using Proxy Mobile IPv6 call anchoring between the MAG function on HSGW and LMA on PDN GW.
Connections between the UE and HSGW are based on Simple IPv6. A11' signaling carries the IMSI based user identity.
