Network & Service Analyzer

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.
