Meaning Feature ID Threshold for downlink edge handover. If the downlink receive level remains less than this threshold for a period of time, the edge handover is triggered. If the GBFD-110601 PBGT handover algorithm is enabled, this threshold GBFD-510501 can be decreased accordingly. If the PBGT handover algorithm is disabled, over-coverage, co-channel interference, and adjacent channel interference may If the downlink received signal level of a neighbor cell is greater than "Min DL Level on Candidate Cell" plus "Min Access Level Offset", the neighbor cell can be listed in the candidate cell queue for handover.
GBFD-110601 GBFD-510501
If the uplink received signal level of a neighbor cell is greater than "Min UL Level on Candidate Cell" plus "Min Access Level Offset", the neighbor cell can be listed in the candidate cell queue for handover.
GBFD-110601 GBFD-510501
Handover threshold during the handovers between cells on different layers or of different priorities. This value is used to suppress inter-layer ping-pong GBFD-110601 handovers. GBFD-510501 Inter-layer handover threshold of the serving cell = "Inter-layer HO threshold" - "Inter-layer HO Hysteresis"; Inter-layer handover threshold of a neighboring cell = Hysteresis value during the handovers between cells GBFD-110601 on different layers or of different priorities. This value is GBFD-510501 used to suppress inter-layer ping-pong handovers.
Reduces ping-pong handovers between cells on a GBFD-110601 same layer. This parameter is invalid when cells are on GBFD-510501 different layers.
Minimum receive level offset. An MS can be handed over to a neighboring cell only when the downlink level of the neighboring cell is greater than the sum of "Min DL level on candidate Cell" and the value of this parameter.
GBFD-110601 GBFD-510501
PBGT handovers to a neighboring cell are allowed only when the downlink level difference between the neighboring cell and the serving cell is larger than this GBFD-110601 parameter. When the value of this parameter is smaller than 64, handovers to a neighboring cell with a lower level than the current serving cell are allowed.
If the UL receive level remains lower than the "Edge HO UL RX_LEV Threshold" for a period, the edge handover is triggered.

Inter-layer HO threshold of the serving cell = "Interlayer HO threshold" - "Inter-layer HO Hysteresis". Inter-layer HO threshold of the neighboring cell = "Interlayer HO threshold" + "Adjacent Cell Inter-layer HO Read & Write Hysteresis" - 64. The value of "Inter-layer HO threshold" can be set through "SET GCELLHOBASIC". When "Current HO Control Algorithm" in "SET GCELLHOBASIC" is set to HOALGORITHM1(Handover algorithm I), "Inter-cell HO Hysteresis" should be set within the range of 64127.

Validation of Modification
Impact on Radio Network Performance
The parameter modification has no impact on the equipment.
If this parameter is set to a smaller value, call drops may occur due to delayed handover; if this parameter is set to a greater value, unnecessary handover may be performed, thus affecting the voice quality.
The parameter modification has no impact on the equipment.
This parameter limits the number of candidate cells. If this parameter is set to a greater value, some desired cells may be excluded from the candidate cells and call drops may occur. If this parameter is set to a smaller value, an unwanted cell may become the candidate cell, thus leading to handover failures or call drops.
