SON (Self Organizing Networks)
Centralised
• SON solutions where SON algorithms are executed in a centralized entity – say, OAM
• In such solutions SON functionality resides in a small number of locations
• More control for operator (less scalable)
Distributed
• SON solutions where SON algorithms are executed at network element (eNB / HeNB)
• In such solutions SON functionality resides in many locations
• Less control for operator (most scalable)
Hybrid
• SON solutions where some of the SON algorithms are executed in the OAM system
while others are executed at the network element level
• Best option, most suited for adhoc networks (for femto / small cells)
• Operator can “move” to Distributed option as and when they have more confidence on
multi-vendor SON algorithms
