Mobile Backhaul Optimization for the

4G LTE Era

Today, mobile network managers’ decisions are about complex dilemmas

To…or Not To…Build and risk more? To…or Not To…Leverage what exists? To…or Not To…Allow more speed? To…or Not To…Migrate now? To…or Not To……

There was a time when, without smartphones, tablets and video streaming, decisions were about a single dilemma

3

Some known facts behind the dilemmas

Increased preference for mobile devices as the main voice and data communication tool

It is anticipated that the number of connected mobile devices worldwide will exceed 10 billion in 2017

Growing smartphone adoption

Surging volumes of data traffic due to widespread use of bandwidth-hungry services

It is anticipated that by 2017, more than 60% of this traffic will be video

2017 11,200,000 Terabytes

2012 885,000

Terabytes

Monthly Traffic Transmitted Over Mobile Data Networks

Both Operators and Mobile Users are impacted

Endless stress on mobile networks

Growing number of connections

Growing data rate per connection

Growing bandwidth requirements

Growing signaling traffic rate (UE)

Threatened QoS

Network congestion issues

Bandwidth exhaustion at hot points – bottlenecks

Threatened QoE

A QoE below mobile subscribers' expectations could translate into subscriber churn and lower ARPU source: Cisco Visual Networking Index – Global

Planning with uncertainty

Revenue-Traffic decoupling challenges mobile operators’ competitiveness

Limits CapEx spending capability

Translates into OpEx reduction plans

Complex, evolving traffic and service forecasting models

Greater sensitivity to changes in end-user/market behavior

As more bandwidth and higher data rate become available, some applications increase data consumption (e.g. streaming video)

Diverse QoE expectations and market segmentation

Business, social networking, entertainment, browsing, mail, E-commerce, Facebook, YouTube,…

Multiple (simultaneous) applications per user

Potentially impacted traffic due to capacity bottlenecks inside the 3G network

• RNC - Radio Network Controller • SGSN - Serving GPRS Support Node • GGSN - Gateway GPRS Support Node • Node B – 3GPP Mobile Radio Station • Nb – Interface between 3G mobile gateways

• IuPS - Interface between RNC and the Packet Switched Core Network

• IuCS - Interface between RNC and the Circuit Switched Core Network

• GN – SGSN-GGSN interface • GI – GGSN to PDN interface
