ALU 9900 Central
By connecting individual subscribers to resource consump­
tion, the Alcatel-Lucent 9900 helps service providers
manage the effects IP-based applications have on wireless
networks. IP applications in use today were not designed
with wireless data network constraints in mind, and as
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.
With the Alcatel-Lucent 9900, service providers can
ensure they make the best possible use of their network
and the precious air spectrum between the network and
the mobile endpoints.
How It Works
Value
The Alcatel-Lucent 9900 is built with two components:
a detector and a central.
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 wireless-specific
net-flow record, which is a subscriber-specific net-flow
record, appended with context specific to wireless data
networks. The deployed detectors securely communicate
this information to the central, which provides GUI-
access to the detectors, reports, forensics, and control.
This information is proving invaluable for wireless
service providers on many levels:
• Operations — It allows service providers to determine
which subscribers, servers, and applications are the
most significant contributors of non-value-add traffic
and load on the network.
• 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 wireless-specific denial of service attacks
targeted at the signaling layer and exhausting RF chan­
nels, as well as the mobile devices that are directly
or surreptitiously participating in the attacks.
• Marketing — It helps service providers determine
the network cost associated with supporting any given
application, thereby enabling application-level ROI
