The market-leading Network & Service Analyzer™ (NSA™) is a suite of fully
automated software applications for troubleshooting and optimization of mobile
networks and services. NSA allows users to trace subscribers’ control and user
plane data both in real time and offline over multiple interfaces and network
elements. Identification of network problems and service quality degradation
(from the symptom down to the root cause) becomes tremendously fast and
easy with this tool. The capabilities and benefits of the NSA can be realized
across LTE, UMTS (including HSPA+), and 2.5G/2G networks. As a result, the
time required to obtain and analyze data from across wireless mobile networks
and in testbed environments is greatly reduced, and carriers and vendors alike
can realize improved network testing efficiency.Improving Efficiency in

Features and benefits
Multi-Technology The NSA Suite is a state-of-the-art troubleshooting
solution for established and emerging mobile network
technologies. It is devised to function optimally in
development, trial and live deployment environments. With
a single software platform, Mobile Network Operators and
Network Equipment Manufacturer engineers can monitor
and test 2G, 2.5G, 3G, HSPA+ and LTE network
environments. With support for a wide range of 3GPP, Vendor- specific and Industry Forum protocols, the NSA
suite of tools helps minimize the time between identifying
that an issue exists and determining its root cause. Thus,
the NSA assists Network Equipment Manufacturers in
meeting the Time-to-Market targets of new features as
well as Mobile Network Operators in continuously
providing their customers with superior Quality of Service
(QoS).
Flexible Hardware PlatformEnsuring the ability to capture high data rates without
data loss is a critical requirement for monitoring today’shigh load networks. This becomes even more crucial as
both new and established networks evolve towards all IP
networks. The K18 and High.Link probes feed the NSA
system with captured traffic in a “stream-store-analyze”
mode to ensure that data integrity cannot be compromised.
Additionally, the K2Air probe can be used in a similar manner
to capture and analyze traffic from the LTE Uu air-interface.
The K18 probes perform real-time capturing under heavy
load from ATM, PCM, Ethernet and Gigabit Ethernet
interfaces. They also perform line-rate hardware filtering
(e.g., control plane/user plane, VPI/VCI, IP addresses) to
allow users to effectively narrow their troubleshooting
activities on a small subset of critical information from the
high volumes of monitored traffic. High.Link probes can be
used to capture large quantities of data in multi-Gbps IP-
based network environments, where both 1G and 10G
transport layer connections occur.

tomorrow’s mobile networks troubleshooting
K2Air Probe for LTE Uu Air-Interface
With the NSA supporting mixed hardware environments
users can easily extend the number and types of probes to
match the requirements of their growing installations.
Auto-configuration and Topology In order to minimize unproductive time used on activities
such as configuring the system for monitoring activities,
the NSA can identify and auto-configure thousands of

3
logical network interfaces and logical links within minutes.
Especially users monitoring complex iub/iur interfaces or
interfaces with channelized STM-1 probes will significantly
benefit from such auto-configuration features.
For static testing environments where traffic load is lower
and a learning phase is undesirable, the Topology and Link
Configuration Editor allows users to manually populate
and/or edit a network topology within a short time span.
Call Table and Call TraceCall Tracing effectively equips users with a magnifying
glass to detect the needle in the haystack of collected
data. By reducing a large number of calls listed in the Call
Table by filter criteria such as a specific IMSI or a release
cause value, users can quickly drill-down into those calls
that require further attention. The selected call shows then
the complete message flow across all relevant network
elements. A Detailed frame view allows down to the bit
analysis of the call trace to facilitate root cause analysis.
NSA's call trace application provides various export
capabilities, from exporting the complete call table to
individual call flows or even frame decodes, thus assisting
the user in creating reports on network problems.

Message-based Statistics and KPIsThe user requires often a tool that can make a broad scan
of the captured traffic and quickly identify potential
problems. An unexpected or unusually high incidence of a
particular event (e.g. RAB assignment failure, can swiftly
be identified by analyzing the statistical distribution of
relevant messages and release causes. By performing
such analysis over time, users can quickly see whether the
issue is related to a particular incident (i.e. a network node
restart), or is spread evenly throughout the testing period.
The NSA allows “drill-up” from individual messages and
events to the related call trace so that users can quickly
investigate the influence of an event on the related user
experience. NSA also provides a comprehensive set of
tools for assessing IP packet level QoS, including
throughput, packet delay and packet loss, displayed in
both tabular and graphical formats.
At other times only Key Performance Indicators (KPIs) that
map complex relationships between multiple parameters
and call phases are sufficient to confirm or refute a
hypothesis. For these cases, the NSA provides a
comprehensive set of KPIs that provide key insight into the
influence that different parameters have on each other.
This allows for domain area identification of service
problems, mapping of service issues to network issues,
and results in reducing the time required for network
optimization and troubleshooting. For maximum flexibility,
users can continuously modify which relationships they
wish to investigate (i.e. is the problem related to a
particular nodeB, a particular cell or a particular handset
type). Drilldown to the calls/transactions behind a KPIprovides the user with the information to go from KPI to
the identification of the problem cause with just a mouse
click. All KPI measurements are stored within an open
MYSQL database, and can be accessed by third party
tools. This allows for easy integration of the solution within
existing measurement systems. For networks with a low to
medium amount of data volume (e.g. in a lab environment)
users can easily define new KPIs (e.g. message counters,
event ratios or delay measurements) within minutes and
integrate these into appropriate KPI reports.

Multi-user support A typical testbed environment can find multiple users who
need to see only a subset of interfaces or handsets that
are under test. Users require full flexibility to filter out and
save data relevant to their test, and do not wish to be
impacted by the applications being used by others that are
sharing the system. The NSA’s Multi-user capabilities allow
users to work completely independently by sharing the
data captured by a common set of probes, and forwarding
only the data required by the individual user to his remote
terminal. Here the user has the freedom to use the NSA
applications of his choice without impacting the
performance being experienced by other users. Multi-user
capabilities ensure maximum system utilization and
efficiency of engineering teams.

NSA for LTE
Air Interface MonitoringIn 2G/2.5G and 3G technologies, significant air interface
information is available on wireline interfaces such as Abis
and Iub. With the implementation of self-governing
eNodeBs within the LTE network, this form of control
information is no longer sent on a wireline interface. Users
are required to move closer to the radio interface itself to
gain key insight into the performance of the eNodeB andthe radio network.
The NSA provides, in conjunction with K2Air, the LTE Uu
probe, air interface insight by supporting promiscuous air
interface monitoring via the CPRI control port implemented
on the majority of eNodeBs. Applications such as call
trace and KPIs seamlessly correlate the wireless
information with information collected on the S1 and X2
interfaces. This capability provides the user with a 360˚
view of radio network performance. Graphical depictions
of key RF physical layer parameters are supported to
investigate RF performance and quality, and can be
analyzed in conjunction with higher layer protocol
information to determine the impact that RF PHYperformance has on service quality, for example.
Additionally, by monitoring key interfaces within the
Evolved Packet Core (EPC), such as the S1, S5, S11 and
SGi interfaces, the user is able to correlate events within
the EPC with their impact on the air-interface.
The NSA platform extends its support to provide market-leading LTE testing solutions

NSA for 2G/2.5G
2G and 2.5G Test Applications
More than 80% of the world’s population is covered by
GSM networks, and a similar percentage of the population
have access to data services via GPRS and EDGE
networks. These legacy technologies provide the
backbone of the 3GPP family and continue to generate
key revenue for Mobile Network Operators and Network
Equipment Manufacturers alike. Mistakenly considered to
be mature technology, the further evolution of data
services (Rel. 7 Evolved EDGE) as well as the move away
from PCM-based towards more efficient IP-based
interfaces, indicate that monitoring and optimization tools
for 2G and 2.5G networks are still very much required.

NSA for CORE
The Core provides the critical transfer functions required to
move data from one part of the network to another and
provides gateways to external fixed and mobile networks.
The core is also where subscriber databases and network
intelligence can be found. The core network is further
evolving with the deployment of softswitch technology and
the continued growth of cost-efficient IMS/SIP-based
services. Mobile Network Operators keen to leverage the
cost savings that this paradigm shift can bring must
ensure that an IP Core can provide adequate quality and
reliability for their voice & data services.
Application Support Auto-configuration
Call trace
Flexible KPIs for call volumes, call success rates,throughput, etc.
