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.”

“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

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

The Solution

Informed decisions and effective

by handset/subscriber visibility

is limited.

1. Detailed flexible xdr data feeds.
