Record the SON log: All the key event of SON

feature will be recorded in the eNodeB or M2000.

LOG records SON feature’s running status, key

event, etc.

eNodeB

SON is fully manageable Setting: policy control and

parameter configuration. Evaluation: evaluate the quality

and the impact on networkeffectiveness of SON feature,

result can be displayed as graph. SON Log: recode the key event

during the SON process

Adaptive ICIC

Highlights:

• Three levels: network-level, cell-level, and UE-level.

• Adaptive ICIC manages and designs the entire network cell edge frequency band

mode automatically using M2000 with high reliability and few manual operations

for routine network maintenance.

Highlights:

• Fast detection of cell outage (by KPI measurement).

• RRM parameter compensation: enable UE moves to neighbor cells and prevent

UE from moving into this cell.

• Recovery and reverse compensation

• RRM compensation covers PS Inter-RAT Mobility between E-UTRAN and

UTRAN / GERAN / CDMA2000
