NEC Small Cell Solutions
NEC Multi-vendor SON for HetNet
NEC’s self organizing network, or SON for short, optimizes the performance of Small Cell Solution.
SON incorporates a variety of eNodeB functions:
1) Automatic self-configuration at the time of installation
2) Automatic operation following installation, i.e. neighbor list and handover parameter optimization
3) Ecological energy saving and self-healing
4) Coverage optimization and load balancing
In addition to the optimization of operations among small cells alone, SON controls interference and optimizes coverage, capacity, power, handover, and load balance in a heterogeneous environment of both small cells and macro cells. In so doing, SON provides efficient, effective infrastructure management for telecommunications operators and the best performance for users.
Automated Functions
ANR/PCI Optimization
CCO (Coverage and Capacity Optimization)
Small cells adapt coverage by adjusting transmission power according to small cell and macrocell loading
- Macrocell raw systems information, such as loading, is available through the OSS
MRO (Mobility Robustness Optimization)
The SON mobility robustness optimization function ensures optimum per-neighbor handover:
- Intra and inter-frequency handover problems between small cells
- Handover problems between macrocells and small cells
Speed Dependent Handover (HO) for Small Cells
Enhances mobility robustness around small cells
High-mobility user equipment would be connected to macrocells while low-mobility user equipment would be connected to small cells
MLB (Mobility Load Balancing)
MLB optimization ensures the best HO parameters in the event of uneven traffic distribution. Network operators benefit from improvements in call blocking rates, system throughput and cell-edge user throughput, as well as reduced capital and operating expenditure. The need for real-time adjustments means that MLB will be operated via eNodeB.
