Aricent Addresses Operator's Two Top Priorities

• The industry’s only blended strategy, design and development engagement

model, helps conceive and commercialize highly differentiated subscriber

experiences

• Innovative services and business models drive increased top line

• Deep expertise in design and usability of connected devices, user

interfaces, applications and more

• Extensive networking design expertise simplifies 4G transition and

optimizes network quality

• Contemporary approach to business processes and systems integration

streamlines operations and reduces costs

• Comprehensive operation and maintenance services further reduce costs

Agenda

• Understand the limitations of existing Service

Assurance Strategies

• The 10 Steps for 4G Service Assurance

• Customer Case Study

• Real time services like video, online gaming and social networking is continuing to

drive demand for differentiated treatment of specific traffic streams

• Multi-access complexity – WiFi, Femto and more

• Growing need to prepare for cloud services

Surge in Data Traffic Straining the Network

Operator ‘3’, in the UK, says that data

now makes up 96% of its traffic

Ovum forecasts smartphone shipments to

grow by 32% between 2009 and 2010

Existing Assurance Systems and Processes predate iPhones and YouTube

Current Mobility Service Assurance Operations

o Network Assurance – Fault and Performance data collected from OMCs and elements

o NMS (In-house or COTS) – silo FM and PM processing, distinct RAN/Core and IP solutions

o Service Management – managing devices, not end-to-end service delivery

o Limited or no information from end-user devices

o KPIs/KQIs defined in deployed systems

o QoS/QoE monitoring is evolving

Step 1: Evaluate and Re-Evaluate

Know where you are going – Vision and Objectives

Examine existing Service Assurance systems and

processes

Leverage external resources to evaluate processes

against best-in-class benchmarks

Step 2: Develop KPI/KQI Model

o Potentially thousands of KPIs/KQIs must be considered

o Understand available KPIs and required KQIs are key to creating an efficient and

effective Service Assurance capability

o Determine immediate and long-term value of KPI/KPQIs

Step 3: Integrated Inventory Management

o Create a reliable, accurate Inventory Management capability that reflects installed

networks and services

o Enable network correlation and root cause identification

o Prioritize problems through service impact and enable comprehensive service

management

Step 4: Automate Trouble/Incident Management

o Enable zero-touch trouble management / incident management

o Accurate network and service inventory is key – identify the correct root-cause and

send technicians to the correct location

Step 5: Implement Centralized KPI/KQI Repository

o Centralize all collected and generated KPIs and KQIs

o Provide central access for all users

o Reduce point-to-point integration between applications

Centralized Repository

Step 6: Implement Service Quality Management

o Rapid identification of service problems (manage QoS)

o Focus on highest revenue services or competitive indicators: retain subscribers

with higher overall ARPU

Step 7: Implement CEM and QoE

Determine what to measure

• Define the relevant Service Level Objectives (SLOs)

• Explicit and implicit SLAs

• End-user devices and other service access points

Define/Review Network Monitoring Requirements (Availability)

• FM and PM with KPI support

Define/Review Service Delivery Monitoring Requirements (SQM)

• Correlation and KQI

Define Usage and Experience Monitoring (CEM) Requirements

• Identify initial devices for monitoring – expand scope over time

• Central point for End-to-end experience monitoring

Handset Issues are the single most influential factor for churn, followed by cost, coverage and quality – Booz, Allen & Hamilton

Step 8: Implement Service Level Agreement Management

o Enable an array of tiered approaches with strict SLA management, including VIP,

enterprise and consumer

o Combine with active Policy Management

Step 9: Integrate 4G Elements

o Implement KPI/KQI changes for new 4G elements e.g. eNodeB and EPC

o Retire 2G and eliminate redundant systems

o Make a decision on Voice - Continue to use 3G voice, or deploy VoIP?

o Implement new services and usage patterns including new KQIs, root-cause and

service impacts

Step 10: Implement Continuous Improvement

Helps you deliver on your Objectives:

o Lower expenses

o Increased subscriber satisfaction and resulting loyalty

o Enhanced ability to respond to change

o Agility to support new services

Adapt to changing requirements,

technology and market

conditions

Define as-is

processes and

architecture

Implement

processes and

system changes

Measure

effectiveness of the

processes and

systems

Case Study: Service Assurance Simplification

Improved Quality and User Satisfaction

SLA based service delivery

Continuous Service Improvement

Improved User Satisfaction

Significant Cost Reduction

30% cost reduction within 6 months through

global delivery approach

Reduced Complexity, Quicker response to

dynamic and evolving contexts

Architectural Simplification

Improved Knowledge / Skill Base

Improved Efficiency and Effectiveness of Delivery

Knowledge retention across domains

Reduced Management Overhead

Simplified Governance, Flexible and Multi-Skilled

Summary

o Learn from your past - every Service Assurance environment is unique

o Bring in an experienced advisor to help design the Best Fit solution for your operations

o Follow the Steps - No shortcuts! Do not kid yourself, positive changes take effort and investment

o Focus on the individual Subscriber Experience; the network and perceived service delivery do not tell the whole story

Future success will ride on the satisfaction of your subscribers
