By connecting individual subscribers to resource consump- tion, the
a result, can easily and unexpectedly burden the radio access network. In fact, subtle changes in the transmission characteristics of wireless data sessions can have a profound impact on network performance.

How It Works
The
The detector monitors data and radius traffic that is mirrored from within the packet core of a 3G/4G network. It generates “events” based on observed behaviors. It also generates a new flow record, which is a
Value
This information is proving inva luable for wireles s serv ice provi ders on many levels:
•Operations — It allows service providers to determine which subscribers, servers, and applications are the most significant contributors of
•Planning — It enables service providers to establish a baseline measurement of network use at the individual subscriber level, allowing more accurate predictions of network capacity trends.
•Engineering — It ensures packet transmissions from devices and networks are consistent with design, and are not being sent fraudulently.
•Security — It allows service providers to detect a new class of
or surreptitiously participating in the attacks.
•Marketing — It helps service providers determine the network cost associated with supporting any given application, thereby enabling
