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

 Agile and cost-efficient deployment

M-CORD Objectives

 Provide customized services and better QoE to customers  Enhance resource utilization

• On-demand deployment
• Virtualized /disaggregated RAN and EPC
• Commodity H/W and open source
• Customized service composition
• Reduced latency and increased throughput
• Differentiated QoE based on service requirements
• Real-time resource management
• Exploit multiple RATs
• Monitoring & analytics framework

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!)

• 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

M-CORD Roadmap
