Alcatel-Lucent 9900 manual Track Behavior at the Subscriber and Network Level

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
