What We Do Know Mobile Telecommunications Impacts The Economy

$1 Trillion+ in CAPEX investment over the last six years

5.1% of global GDP by 2020

10% more penetration gets you 15 basis points

5.9 Billion mobile broadband connections by 2020

83% of the global population!

50 Billion connected devices by the end of the decade

What We Do Know With Context, the Internet Will Come to You

“Instead of the consumers going to the internet, the internet will come to them…”

-Gerhard Fettweis, Siavash Alamouti


What We Do Know There’s Considerable Intelligence in Signaling Messages

Diameter is a next-generation signaling protocol

Highly extensible

Attribute Value Pairs (AVPs) support a wide range of network specific data

Used on over 80 interfaces

What We Do Know Wi-Fi Will Play a Critical Role in Extending Coverage

I am a Wi-Fi Hotspot

By 2018, more traffic will be offloaded to Wi-Fi than what remains on cellular

71% of all communications currently flow over Wi-Fi

Wi-Fi can reduce per-bit RAN costs by up to 18%

What We Do Know Competition is Fierce

Competition comes in all shapes and sizes

Need to roll out networks faster

Need to roll out services faster

Take a portfolio approach

Differentiate on quality

Accelerating Vendor Interoperability

Challenge: OCS cannot process Diameter Credit Control messages from different NEMs What’s at stake:

• Long lead time and high cost on development work

• Months of wait time and tens of thousands of dollars

• Impacts performance and service rollout

GGSN placing information for called-station-id in top grouped AVP Far end OCS expecting information in grouped AVP Can impact session binding between GGSN and OCS

Accelerating Vendor Interoperability

GGSN placing information for called-station-id in top

grouped AVP

Far end OCS expecting information in grouped AVP

Can impact session binding between GGSN and OCS

Diameter Signaling Controller

DSC copies AVP parameter in CCR-I and CCR-U messages in grouped AVP on inbound message from GGSN to top level AVP on outbound message to OCS

• Faster time-to-market and time-to-revenue

• Lower operational costs • Agility - rapidly interwork different vendor
