3Optimize Wireless Networks for Data
By connecting individual subscribers to resource con-
sumption, the Alcatel-Lucent 9900 WNG helps you
manage the effects that IP-based applications have on
your wireless network. More importantly, it allows you to
ensure you make the best possible use of your network
and the precious air spectrum between the network
and the mobile endpoints.
With the Alcatel-Lucent 9900 WNG you can:
• Monitor both Internet-mobile and mobile-mobile
traffic
• Access a real-time view of how a subscribers’ usage
(including intended, unintended, and malicious)
translates to load across a wireless data network
• Identify anomalous usage behaviors as they relate
to network performance and availability
• Identify which subscribers, servers, and applications are
contributing to network loads when those loads exceed
prescribed limits
• Perform surgical mitigation and network optimization
via elements in the network
• Manage unwanted activity using bespoke mitigation
strategies, and thereby improves network capacity
utilization
Track Behavior at the Subscriber
and Network Level
The Alcatel-Lucent 9900 WNG is offered with two
components that allow you to monitor network behavior
at the subscriber and network level (Figure 1).
The Alcatel-Lucent 9900 WNG Detector is deployed
in the packet core on a mirrored port:
• Between the packet data serving node-HA (PDSN-
HA) and PDSN-authentication, authorization and
accounting (AAA) system (PDSN-AAA) in CDMA
networks
• Between the serving general packet radio system
(GPRS) support node (SGSN)-gateway GPRS
support node (SGSN-GGSN) and SGSN-AAA
in GPRS/UMTS networks
• Between the access service node-home agent
(ASN-HA), ASN-AAA in WiMAX networks
