Optimize handover success rate
1. Pucch power control cycle (20ms)
This parameter is used to configure the power control period of
PUCCH
MOD CELLPCALGO:LOCALCELLID=1,PUCCHPCPERIOD=1;
2. Pucch power control target SINR bias (dB)
This parameter is used to configure the offset of the PUCCH power
control SINR target value.
MOD CELLPCALGO:LOCALCELLID=1,PUCCHPCTARGETSINROFFSET=10;
3. Uplink shared channel transmit power spectral density control
target
This parameter is used to set the PUSCH transmit power spectral
density level of common users after the uplink scheduling control
power switch is turned on. The larger this parameter is
configured, the higher the PUSCH transmit power spectral density
of ordinary users. If it is configured as ADAPTIVE, the PUSCH
transmit power spectral density of ordinary users will be
automatically adjusted according to the network load. This
parameter applies only to TDD.
MOD CELLPCALGO:LOCALCELLID=1,PUSCHPSDCTRLTARGE T=8;
4. HARQ algorithm switch & TDD HARQ-ACK feedback mode
configuration optimization switch
This switch indicates the configuration optimization switch of the
HARQ-ACK feedback mode of the TDD system. If the switch is on, the
HARQ-ACK feedback mode can be reconfigured according to the
service conditions of the UE; if the switch is off, the HARQ-ACK
feedback mode will not be performed according to the service
conditions of the UE. Reconfiguration of feedback modes. This
parameter only applies to FDD and TDD.

5. Switching process control switch & carrying process priority
switch
Bearer flow priority switch: This switch is used to control the
handling strategy when switching and bearer flow conflict. When
the switch is turned on, when there is a conflict between the
handover and bearer establishment, modification or deletion
procedures, if it is not CSFB or the QCI1 bearer release procedure
conflicts with SRVCC handover, the bearer procedure will be
prioritized. If the CSFB or SRVCC handover procedure conflicts
with other bearer procedures , the handover process is
preferentially processed; when the switch is turned off, when the
handover and the bearer establishment, modification or deletion
process conflict, the handover is preferentially processed. This
parameter only applies to FDD and TDD.
MOD GLOBALPROCSWITCH:HOPROCCTRLSWITCH=ErabFlowFirstSwitch -1;
6. Optimize the handover preparation failure penalty timer (30
seconds)
This parameter controls the timer duration for punishing the
preparation failure of optimized handovers (including handovers
based on frequency priority, service-based handovers, SPID-based
handovers back to HPLMN, and QOE-based handovers) other than
MLB. This parameter only applies to FDD and TDD.
MOD HOMEASCOMM:OPTHOPREFAILPUNISHTIMER=1;
7. Resource class switching preparation failure penalty timer
(seconds)
CSFB, coverage-based, uplink quality-based, and distance-based
handovers belong to the necessary classes. After the resource
class handover preparation fails, the shorter the penalty timer
time setting is, the more invalid handover requests are initiated
after the resource class handover preparation fails; The longer
the penalty timer is set, the fewer invalid handover requests are
initiated, but if the time is too long, the UE may drop calls due
to untimely handover.
MOD HOMEASCOMM:RESHOPREFAILPUNISHTIMER=50;
8. The number of penalties for failure to prepare for non-resource
switching (times)
After the non-resource handover preparation fails, the smaller the
penalty, the more invalid handover requests are initiated after
the non-resource handover preparation fails; the larger the
penalty, the fewer invalid handover requests are initiated, but
the penalty is too high In many cases, the UE may drop calls due
to untimely handover.
MOD HOMEASCOMM:NONRESHOPREFAILPUNISHTIMES=50;
9. Number of retries for non-resource switching preparation
failures (times)
After the non-resource handover preparation fails, the smaller
this parameter is set, the less chance of retry, and the greater
the probability of handover failure; the larger the setting of
this parameter, the more chance of retry, the greater the
probability of successful handover attempt, but also It will
increase unnecessary signaling waste.
MOD HOMEASCOMM:NONRESHOPREFAILRETRYTIMES=1;
10. Proprietary GAP measurement mode
When the parameter value is GAP mode 0, the CSFB measurement
frequency point identification time is short, and the density of
measurement samples per unit time is large, which has a great
negative impact on the maximum throughput rate of the UE that
starts GAP; when the parameter value is GAP mode 1 , CSFB
measurement frequency identification time is long, and the density
of measurement samples per unit time is small, which is more
likely to cause switching failure and call drop.
