• Network Planning Tools: Infovista (Mentum), Forsk, TEOCO

2) Traffic Shaping Variant (Services – eg: streaming video, web browsing)

• Real-Time Traffic Shaping / Adaptive Traffic Management

• Uses Deep Packet Inspection (DPI) to identify make of traffic

• Policies and advanced techniques (caching TCP optimization, etc) to optimize traffic

• Solutions: Vasona Networks, ByteMobile, BroadHop, Aircom

• Accurate predictions of when a given carrier on a given cell sector will need to be expanded

• Inputs taken from the OSS and Operators’ growth forecasts

• Solutions: TEMS Capacity Manager

Key Network Capacity Planning and Management Challenges

Forecasting Traffic Growth - across multiple services

• For each service• Sales forecast• Usage forecast• Data performance

requirements• Capacity impact

Translating Forecast Traffic into Network Load

• Combining different traffic types

• Modeling network loading

• Identifying resource bottlenecks

Working Across Multiple Networks & Capacity Options

• Comparing impact of different capacity growth options (and timelines)

• Managing load across networks• 4G, 3G, Wifi,

Plan Network Expansion “Just-in-time”• Improve CAPEX and OPEX Efficiency

• Avoid premature expenditures in network expansion

Optimize Capacity Management• Efficient management of existing network

resources/elements

• Eg: unbalanced sector, relocate low usage elements

Forecasting Traffic growth • Perform Element Level Trending to estimate the

date when capacity will be exhausted

• Prioritize expansion based on revenue contribution per cell/ Network or regional level “top N”

Manage User Experience• Network Capacity focus on achieving and

maintaining User Experience KPIs (eg: to achieve 1Mbps Data & 2% blocking Voice-RRC)

• Provide consistent User Experience across different equipment vendors and technologies

“What-if” Analysis• Experiment effect of configuration changes,

varying traffic loads, constraining resources, and other special events on a network, and determine how to best remediate a capacity problem

Easily Visualise Cell Performance

Green dots are hourly traffic samples. Samples within the blue surface are meeting their user experience KPIs.

Headroom Report

11

Generate Reports showing which sites/cells need to be investigated in more detail.

Reports can be customized to only include nodes with headroom below a custom threshold, or nodes that are forecast to run out of capacity within a given timeframe.

Identifies Impacted Services & Limiting Resources

12

Quickly Identify Resources that are Limiting Performance

Impacted Services shows which services are (in danger of) exceeding KPIs.

Limiting Resources indicate which resource is causing the service to exceed KPIs.

Time to Expansion Report: Prioritized by Revenue

• Revenue per site calculation factors in revenue per MB or Erl per service and traffic mix

• Customizable calculations –so carriers can match their ARPU and way they relate per service traffic to revenue

• Can also be weighted to favor different services – iesupport a marketing driven focus on video

Including revenue per site enables prioritization based on potential revenue impact

Quickly Identify when a Cell will run out of Resources

The dashed lines show traffic forecasts for different traffic types. When the dashed line crosses into the red region KPIs are no longer being met.

“What-if” Analysis Use Case: Designing Site Capacity Expansion

TEMS Capacity Manager establishes a set of models customised to each cell/site. These models can also be used in “what-if” experiments to determine how configuration

changes, or different traffic loads will impact per service performance.• RAN engineers can use this experimentation capability to investigate how best to remediate a capacity

problem. • TEMS Capacity Manager will:

• Identify the constraining resource(s) • Allow the engineer to compare solution options by re-running

the analysis as if each capacity expansion solution had already been implemented.

• This capability is also useful for special event planning: experimentation on individual network elements can be performedto understand impact of predicted load

Any combination of configuration changes, environmental changes, KPI changes and traffic changes can be made in each experiment.

“What-if” Analysis Use Case: Understanding KPI targets vs Capacity Example: With a median downlink user throughput KPI target of 3 Mbps this LTE Cell is operating

with 25% spare capacity for a KPI. Modifying the KPI to a 10 Mbps median has a severe impact.

“What-if” Analysis Use Case: Predicting Impact of Traffic Growth

Example: Model impact of doubling LTE Traffic

Identifying the Need for Small Cells, Hetnets, or Re-Farming

Comparing element level trending (in blue) with spectrum (capacity) availability (in red) allows for a micro layer strategy to be evolved “just in time” and assists in devising spectrum re-farming strategies that can maintain user experience.

When total WCDMA & LTE payload at this site reaches this level, macro layer spectrum will be exhausted.

The operator has knowledge of when more spectrum is required and/or

when a micro layer capacity offload solution needs to be implemented.
