Feature

Benefit

Direct Tunneling

Reduces latency by creating GTP-U tunnel for data transport between the RNC and the
GGSN while optimizing SGSN usage for control plane processing and user plane
functionality for cases such as roaming and lawful intercept.

L2TP Tunneling

Layer 2 Tunneling Protocol (L2TP) support encapsulates data packets between an L2TP
Access Concentrator (LAC) and an L2TP Network Server (LNS) to create a Virtual Private
Network (VPN).The system can be configured as either an LAC or LNS in support of
L2TP.LAC is an optional licensed feature.

Lawful Intercept (optional
licensed feature)

Provides Telecommunication Service Providers (TSPs) with a mechanism to assist Law
Enforcement Agencies (LEAs) in the monitoring of suspicious individuals (referred to as
targets) for potential criminal activity.

IPSEC

Secure VPN Connectivity for the enterprise.Secure L2TP and mobile IP tunneling.System
architecture provides IPSEC implementation with no performance degradation.Encryption
Daughter Card (EDC) availability for hardware-based encryption.

OSPF Routing

Provides optional OSPFv2 routing with NSSA support.

BGP-4 Routing

Provides optional BGP-4 routing.

Flow-based Traffic Policing
(optional licensed feature)

Provides the traffic policing to control session flow on a flow classification basis.Provides the
QoS to control session flow on a flow classification basis.

Traffic Policing and Shaping
(optional licensed feature)

Provides the ability to limit network bandwidth on a per subscriber basis.Provides the ability
to buffer packets which exceeds the allowed limit and transmit them once the traffic flow
comes below the exceed limit.

Dynamic QoS Renegotiation
(ECS support required)

Provides the ability to manage the risk of bandwidth mis-appropriation. This feature allows
the Enhanced Charging Service (ECS) to analyze application traffic, and triggers QoS
renegotiation with the AGW to optimize service performance.It provides Network Controlled
QoS (NCQoS) and traffic class-based QoS renegotiation support.

GTPP Server Group support

Provides more than one list of GTPP servers through GTPP server group feature at
context level for GTPP accounting functionality

Provides GTPP accounting functionality to individual subscriber through APN

Session Redirection (―hotlining‖)
(optional licensed feature)

Provides the ability to redirect subscriber traffic to an external server through the application
of Access Control List (ACL) rules.Relies on the Change of Authorization (CoA) feature for
the dynamic redirection of subscriber IP datagrams.

PDSN RAN Optimization

Provides session redirection based on sessions having a specific MSID or received from
specific PCF zones.

Change of Authorization (CoA)
and Packet of Disconnect
RADIUS message support

Allows system contexts to listen for and act upon CoA and/or disconnect messages from a
RADIUS server.CoA messages enable the dynamic changing of subscriber
attributesDisconnect Messages (DMs) allow the termination of subscriber sessions from a
particular RADIUS serverCoA is supported for use with PDSN.

RADIUS Server Group support
(optional licensed feature)

Provides more than one list of AAA servers through RADIUS server group feature at context
level for AAA functionalityProvides AAA functionality to individual subscriber through
realm (domain) APN
