Neigbourcell Configuration - Measurement Configuration
- NeighbourCell and Measurement Configurations are prepared.
NeighbourCell Configuration includes:
- neighbour_gNB_ID (This is needed for AMF to identify gNB exists in it's context
- neighbour_nr_cell_id (This is needed for target gNB)
- neighbour_physical_cellId (This is needed for UE in the meas report)
- neighbour_absoluteFrequencySSB (This is needed for UE in meas report)
- neighbour_subcarrierSpacing (This is needed for UE in meas report)
- neighbour_mnc (This is needed for AMF)
- neighbour_mcc (This is needed for AMF)
- neighbour_mnc_length (This is needed for AMF)
- neighbour_tracking_area_code (This is needed for AMF)
NR Measurement Event Configuration Includes:
- enableA2 & enableA3 (gNB activates the event reporting according to these vars)
- thresholdA2 & A2_TTT (configurable reporting parameters)
- thresholdA3 & A3_Hysteresis & A3_TTT (configurable reporting parameters)
Concerning the above:
- These parameters are read in the configuration parsing part and written under RRC structure
- Event Based Measurement Configuration is prepared according to enableA3 parameter.
- Measurement Configuration of UE is cloned under UE Context. When a measurement report comes,looping through the UE's meas config and matching the measIDs. With this measID, report configs extracted and processing in different ways.
