Mobile CORD (M-CORD) - Enabling 5G on CORD Kang-Won Lee (kangwon@sk.com) SVP of R&D, Network IT Convergence

Operator Challenges State of the infrastructure: Built with closed proprietary boxes • Inefficient utilization (including sub-optimal use of radio resources) • Inability to customize for different users • Slow in creating innovative services • Cannot support industry-specific IoT scenarios Mobile infrastructure needs re-architecting for 5G

M-CORD Objectives  Enhance resource utilization • Real-time resource management • Exploit multiple RATs • Monitoring & analytics framework  Provide customized services and better QoE to customers • Customized service composition • Reduced latency and increased throughput • Differentiated QoE based on service requirements  Agile and cost-efficient deployment • On-demand deployment • Virtualized /disaggregated RAN and EPC • Commodity H/W and open source

M-CORD Vision 5G Enabling Platform - Enable virtualized/disaggregated RAN and Core - Deploy network functions as services - Leverage best practices of SDN, NFV, Cloud - At mobile edge (but not limited to it!)

M-CORD Roadmap 1. RAN/EPC disaggregation – Disaggregate control-plane / user-plane of eNB and EPC 2. Connectionless Service – Provide light and efficient connectivity for IoT use cases 3. Real-time analytics (A-CORD) – Employ analytics framework for real-time monitoring and reacting 4. Mobile edge computing – Develop customized edge service use cases for subscribers and enterprises 5. Network slicing – Provide flexible logical networks that supports use cases with different requirements
