• Paper Objective and Contribution
WHY SON ? (NICE QUESTION)
• Reducing manual intervention or least possible human interaction.
• Atomization of repetitive process. • Improve runtime operation/optimization based on real time data analysis. • Improving user experience and network performance.
BASIC FEATURES OF SON
SELF CONFIGURATION • All the configuration procedures necessary in order to make the network operable. • Self Configuration Use Cases • Plug & Play : IP Address allocation, Authentication, Software and Configuration Download from OAM.
• Planning radio parameters of a new eNB: handover & cell selection thresholds, power settings, etc. • Establish connectivity with other nodes: Automatic Neighbor Relation (ANR)
SELF OPTIMIZATION • Continuous optimization of the BSs and network parameters in
order to guarantee a near optimal performance. • Self Optimization Use Cases • Backhaul Optimization
• Coverage and Capacity optimizations • Antenna parameters optimization • Interference management
• HandOver (HO) parameters optimization • Load balancing
SELF HEALING • Continuously monitor the system in order to ensure a fast and seamless recovery. • Self-diagnosis: create a model to diagnose, learning from past experiences. • Self-healing: automatically start the corrective actions to solve the problem. • Significantly reduce maintenance costs. • Self Healing Use Cases • Cell outage detection and compensation : Antenna tilt and the cell transmit power
• Self-healing of board faults
