• COnvergence of fixed and Mobile BrOadband access/aggrega3on

networks

• Large scale integra3ng project
• Work programme topic: ICT- 2011.1.1 Future Networks

COMBO FMC: Network Convergence is in focus

Common architecture requires – § Structural convergence

§ Common use of infrastructure, technology, interfaces, transport mechanisms

§ Func3onal convergence

§ Unifica3on of fixed and mobile network func3ons and services

Fixed and mobile networks – § developed independently § limited joint usage of infrastructure § independent network opera3on, control and management § convergence only at service level (e.g. IMS)

Why network convergence is needed

• Increasing number of users and

connected devices

• Access any content any 3me

anywhere from any device

• Demand for video streaming – for

fixed and mobile customers

• Increasing Wi-Fi traffic
• Tight price pressure on telcos: Reduce

CAPEX/OPEX, Generate new revenue, Improve user experience

• Unified hardware resources –

for both fixed and mobile services

• Cost and energy savings
• Increased revenue
• Improved customer experience
• Network infrastructure with

end-to-end management and

• rchestra3on capabili3es

Drivers Expected benefits Broadband subscribers Connected devices Video contents Online services New technologies

Traffic increase

Illustra3on of fixed and mobile traffic increase

• Based on the real German

network topology, popula3on and Cisco’s traffic evolu3on studies

• Overall mobile traffic will grow

from 1.6% to 7.3% from 2012 to 2017

• Average traffic in 2017 will be

4 Gb/s at the regional PoP and 200 Gb/s at the core PoP

• Mobile traffic growth alone is

not a driver to change the aggrega3on network structure

F&M German networks F&M traffic forecast

Fixed Mobile Peak Traffic at busiest regional and core POPs x20

Today’s segmented networks

Potential for network optimization through –

• Converged network control and operation → functional convergence
• Converged transport for mobile and fixed network → structural convergence

Huge variation in terminal equipment and technologies Simple sharing

• f aggregation

infrastructure – no common technology base Different IP edge solutions per technology Fixed and wireless have separated control, operation and management

Network convergence reference framework

CO Main CO Core CO Approximate numbers of customers per service area several 1,000s to 10,000s a few 10,000s to ~100,000 1,000,000s IP edge can be here or somewhere else – COMBO will assess

Target benefit: Converged access and aggregaSon technologies

Objec3ve:

• universal access and aggrega3on technology
• scaling for traffic growth
• scaling for number of user equipment

Target benefit: Universal access bundling for residenSal gateway

Objec3ve:

• Integrated hybrid access to residen3al end-users
• Dynamic bandwidth using fixed and mobile technologies
• Benefits:

– One authen3ca3on for the customer – not per technology – More efficient network management for the operator – Improved network performance and user experience
