This SON tutorial is part of the 3GPP Self-Organizing Networks series (#3GPPSONSeries). In this part we will look at what features were defined as part of 3GPP Release-9. At a high level, we can say that the main focus of 3GPP for SON in Release-9 was Self-optimization. There are many different self-optimization use-cases that have been discussed as part of Rel-9. In this video we will look at Self-optimization at a very high level and discuss some of the use cases and features in the following videos. All our #3G4G5G slides and videos are available at: Videos: https://www.youtube.com/3G4G5G Slides: https://www.slideshare.net/3G4GLtd SON Page: https://www.3g4g.co.uk/SON/ 5G Page: https://www.3g4g.co.uk/5G/ Free Training Videos: https://www.3g4g.co.uk/Training/

2. Three stages of SON
©3G4G
•Plug and Play (PnP)
•Faster Rollout
•Consistency
•Licensees, Hardware Inventory and Software build
•Efficient resource utilization
Self-
Configuration
•Mobility Robustness Optimization (MRO)
•Mobility Load Balancing (MLB)
•Minimization of Drive Testing (MDT)
•Fast and proactive parameter optimization
•Increased Network performance
Self-
Optimization
•Fast, autonomous failure mitigation
•Continuous performance monitoring
•Faster Network maintenance
•More efficient resource utilization, less effort
Self-
Healing

3. Self-Optimization Use Cases

• Support for a centralized optimization entity
• Neighbour list optimization
• Interference control
• Handover parameters optimization
• QoS-related parameters optimization
• Load balancing
• Common channels optimization
• Radio parameters optimization for home nodes
• Transport parameters optimization
• Routing optimization
• Energy saving

4. SON Features in Release-9
©3G4G
• Release-9 has been focused mainly on Network Optimization
procedures.
• The following features have been defined in Rel-9
• Mobility Robustness (MRO) and Handover Optimization (HO)
• RACH Optimization
• Load Balancing Optimization
• Inter-Cell Interference Co-ordination (ICIC)
• Load Balancing Optimization was just discussed as part of MLB
• ICIC was covered earlier as well
