2019 Priorities for Communications Infrastructure
1. Better broadband and mobile – wherever you are: helping to encourage investment and improve broadband and mobile coverage across the country, so everyone benefits from the services they deliver.
2. Fairness for customers: ensuring that broadband, phone and TV customers, particularly vulnerable people, are treated fairly.
3. Encouraging Innovation as a bridge between Universality and Fairness –increasing role as facilitator and convenor
4. Supporting consumers and industry through Brexit: looking after the interests of UK consumers and the communications sector as we exit the EU.
5. Strong, secure networks: working with communications companies to help ensure their networks are strong, secure and protected against outages or cyberattacks

How innovation can help improve rural coverage
Technical Innovations: Emerging technical can reduce cost and extend reach. Ofcom will continue to look at ways it can facilitate this e.g. our work to license-exempt self-installed mobile repeaters
Collaborative Measures: Ofcom’s Advice to Government on Options for Improving Mobile Coverage
identified other potential levers:• Public subsidy to fund further rollout of coverage. • Infrastructure sharing between operators.
• Further easing of planning barriers. We also considered rural roaming and concluded that the surest way to deliver benefits through such an approach would be collaborative arrangements between operators

Challenges and opportunities to scale Performance
• Spectrum variety, Dynamic allocation and sharing
• vRAN dynamic reconfiguration based on real-time usage
• Multihost networks –dynamic capacity reallocation based on real-time load
• 3-D beamforming, beamsteering, beamshaping
• Rapid NFV intruder / anomaly detection and seclusion
• Automated network slicing, slice reconfiguration
• Programmable networks – edge-core application fluidity
• Ultra-resiliency trade-off with Ultra-security: vResiliency (Virtual Resiliency?)
• We can imagine many more …..
5G and other new technologies bring a huge increase in complexity, add real-time requirements and a new dimension to security with NFV: automation and ML/Real-Time analystics will be critical

A holistic approach to scalable performance and resiliency: Transport sector example
Better understanding of market inhibitors, working alongside Government, developing appropriate regulation
• Optimal use of resources along railways and roads:
• Programmable networks and dynamic allocation of resources (bandwidth, power, capacity)
• Dynamic spectrum sharing to follow transit passengers (eg local license for 3.8-4.2 Ghz along railway line) adapting to peak commuter traffic
• Synergies
• Connectivity to roads, rail, remote areas
• Operational rail, consumer broadband, autonomous cars

A New Approach to Assurance for Network Security & Resilience

Classification: CONFIDENTIAL

A robust security & resilience assurance framework is essential
This assurance framework requires continual proactive testing and proactive technical, organisational and commercial measures
Identify those network elements key to network availability & propose systematic preventive hardware, software and process checks to improve network availability and resiliency;
A code of best practice to reduce the time required to reconnect subscribers following a large-scale network outage
5G networks providing services on a significant wholesale basis or to critical industries, to offer greater levels of redundancy and resilience in the control plane.
Work with international standards organisations to implement new standards for interworking between elements.

A new approach to Standards for ultra-resilient networks
Traditional standards approached is based on normal mode of operation
Future standards should be designed for 3 modes of operation:
1. Normal Mode of Operation
– As per existing approach, but must embrace multi-access & multi-tier resiliency
2. Unstable Mode of Operation
– Applies following a large scale “shock” or attack
– System or network level instability or “flapping”
– Priority is “back-off” between elements to restore system stability
– Currently poorly addressed by standards
3. Outage Mode of Operation
– For large-scale regional or national outage
– Priority is to provide minimum level of service asap (eg local autonomy)
– Short-term balance between restoring service and network security

Requirements to underpin the new 5G network assurance & resilience framework
Details will be subject to consultation between Ofcom, Government and industry
Areas of focus are likely to include:
– Business and governance processes to enhance security
– Network design & build to enhance security
– Networks to be securely managed & operated, and
– Vendor procurement and ongoing management to support network security.
Virtualised networks components using Open-Source software: particular care must be taken to systematically deploy software updates in accordance with the faster development cycles for such software
Virtualisation should be harnessed and engineered to maximally scale resiliency and security in real-time or near real-time: vResiliency
