Achieving Complete LTE Readiness Accelerating The Connected World
"As we maintain and deploy America's most
advanced 4G LTE network, we knew we needed a
monitoring solution that helps assure that our
services perform seamlessly for our customers.
Tektronix Communications' customer driven
innovation approach resulted in a solution uniquely
capable of meeting our business and
operational requirements.”
Nicola Palmer
Vice President of Networks
World’s First Large-Scale LTE Network
“Achieving Complete LTE Readiness” ?
• It’s not enough to build and deploy a “functional”
network
– OSS and BSS must also be set up from day one to minimize
technical and financial risks
– Operators must recognize a return on their huge investments —
FAST
• It’s too expensive and inefficient to deploy systems for
LTE as independent silos
– LTE networks are going to operate in parallel with 3G networks
for quite some time
Operational Readiness
Commercial Readiness
Functional network with all necessary OSS for
performance management, troubleshooting, etc.
from lab testing through FOA to live network
Integration with mission-critical BSS such as
billing, fraud, customer experience, etc.
Operational Readiness
• Conformance and operation within the LTE network
• Interoperation with other networks
• Troubleshooting tools and processes for Tier 2-3
• Proactive performance monitoring
• Manage traffic growth and continuous network expansion
Commercial Readiness
• Early, efficient integration with BSS and processes
• Empowering customer care
• Manage new revenue and service strategies
• Track subscriber behavior and service usage
Carriers’ Concerns – EPC/LTE

with carriers’ showing
concern on the growth

Interoperability between

carriers’ show concern
over NEM
implementations
1. Provides complete visibility to hand
downs from LTE.
2. Enables reporting, monitoring and
troubleshooting across technical
borders from one system.
3. Supports an unlimited number of
hops.
Cross-Network
Visibility
LTE is not an island. As many other
networks play an important role,
interoperability carries great significance.
Setup alone for an LTE session requires
at least 10 hops and hand-downs to 3G
only extend the required visibility.
The Solution
Multi-network, Multi-hop Support
Addressing LTE’s Unique Challenges
! Unless a system can capture all
the hops you will miss critical
pieces of information needed to
manage interworking networks.
1. Patent-pending mapping algorithm efficiently decrypts and correlates subscriber identities including GUTI, IMSI, MSISDN.
2. Real-time capture is superior to sampling—elimination of post-processing ensures critical messages are captured.
Full Subscriber-based
Correlation
GUTIs provide the key to associating
activity with a particular subscriber IMSI.
In LTE environments, this temporary ID
changes less often than in 3G due to
inherent security measures and may
remain unchanged for more than 24
hours.
The Solution
Complete and Quick Retrieval of
all Associated Messages
Addressing LTE’s Unique Challenges
! Failure to capture, decrypt and
correlate the IMSI to the GUTI
when it occurs compromises
data integrity and visibility to
the subscriber.
1. Auto-discovery eliminates the
manual and error-prone
intervention otherwise required to
begin monitoring.
2. Auto-discovery accelerates
visibility to new node activity.
Automatic Network
Discovery
As LTE networks are rolled out,
engineering resources turn up 100s of
eNodeBs each day.
The communication of these
voluminous field activities impacts a
monitoring system’s performance.

New Monitored Nodes are Reflected
Immediately in the System
Addressing LTE’s Unique Challenges
! Without the ability to
automatically detect and
monitor new nodes, visibility to
the nodes performance is either
delayed or lost.
1. Critical performance metrics are presented and updated every 60 seconds in a single dashboard view.
2. Degrading service is detected immediately allowing rollback or other corrective actions to be taken to minimize the impact.
Real-time Visibility to
Change Control
LTE networks undergo frequent change
due to software updates and expansion
of LTE coverage and the support of IMS,
DIAMETER and other services.
LTE’s complexity requires visibility to
these changes in order to prevent failures
and outages.
The Solution
Minute-by-minute Analysis Highlights
Failures Needing Action
Addressing LTE’s Unique Challenges
! Without real-time procedural-
based KPI visibility to a node’s
behavior before, during and
after a change is committed can
delay the triggering of alarms.
1. Provides for end-to-end signaling and media visibility across multiple network domains.
2. All mobile voice QoE measurements are available for each call and node.
3. Proven experience in assuring voice in any domain.
Integrated VoLTE
Service and Media QoE
As mobile voice services are a leading
source of revenue, ensuring service
QoE for VoLTE and fallback networks
is imperative.
Subscribers have high expectations
around voice quality that must be met.
The Solution
Voice Quality Analyzed
in LTE Networks
Addressing LTE’s Unique Challenges
!
Without flexible and secure
media capture, analysis and
playback within the same
system, productivity in
troubleshooting is reduced.
1. Tagging and separation of User
DNS from Infrastructure DNS
allows for a better view of what
matters most.
2. Support for DNS Timeouts
including provisioning and IMS
core changes.
DNS Traffic
Discrimination
DNS-managed routing selections require
interaction with the IMS Core. When not
working, nothing gets routed. Heavy DNS
is also used for User Plane traffic.
As DNS is a critical function, it has major
impact if it is not working properly.
The Solution
Ladder Filtering Provides Focus
on Key DNS Messages
Addressing LTE’s Unique Challenges
!
Without DNS Discrimination,
messages can get lost in the
noise. If the ones that matter
cannot be found in a timely
matter, network outages can
Result
1. Troubleshoot sessions with complete user plane data.
2. Eliminate need to recreate issues by retrieving automatically captured data.
3. While data summaries keep data readily available, complete drill-through to full UP detail is only a few clicks away.
Subscriber-based
Control Plane
While over 90% of LTE bandwidth is User Plane, the correlation of UP to CP remains critical to solving complex LTE issues.
Reveal how your bandwidth is being used and analyze destinations and subscriber use in detail over time.
The Solution
Addressing LTE’s Unique Challenges
!
Without near-line rate
deciphering capabilities, a
system cannot accurately and
consistently associate control
plane data with individual
subscribers.
Complete Visibility into
Subscriber Service Performance
1. Supports Monitoring the LTE RAN via eNodeB Trace Port, 24*7
2. Multiple protocol correlation capability by including radio resource management information on per subscriber per session basis
3. Trouble shooting eased by correlation of all interfaces from RAN to core network in Call Trace
Insight into Radio
Management
In LTE network, the RAN intelligence
(i.e radio resource management) is
built within eNodeBs

Complete visibility to the data pipe is
required to maximize the return on
deployed assets and improve the
subscriber experience.
Drive better PCRF and charging model
decisions, fine tune the network for
growth and resolve complex issues.
The Solution
Informed decisions and effective
actions require visibility.
Addressing LTE’s Unique Challenges
! Without a common view of CP
enhanced with DPC UP, service
by handset/subscriber visibility
is limited.
1. Detailed flexible xdr data feeds.
2. Includes multi-domain, multi-hop, multi-data sources.
3. Provides full UP + CP record correlation, normalization and mapping.
4. Can support multiple applications including TekComm CEM offerings.
Support for
Commercial Readiness
While BSS integration accelerates LTE
commercial readiness from day one, the
cost and complexity of capturing critical
business data must be minimized.
