Hello Sir,
Please find below details :
1. Alternate ZTE Parameter name instead of Directed Retry(drInd_0),
pls using cell setting:

InterfBoundary Interference BTS needs to measure CELL_TABLE Cell (0~5) None (0~5) [0, 10, [0, 10, 15, 20,
Band interference on the 0: -110 0: -110 15, 20, 25, 63]
Boundary unallocated traffic channels. dBm, 1: dBm, 1: 25, 63]
BTS calculates the average -109 -109
of recent interference values dBm, dBm,
on periodic basis and ……, ……,
converts it into 63: -47 63: -47
corresponding interference dBm dBm
band information. BTS then,
transfers to BSC in the RF
RESOURCE INDICATION
message to consider it as a
factor in channel allocation
strategy.
The interface boundaries are
used to help the conversion
of the interference level
(average) value into
corresponding interference
band information. Altogether
six boundaries determine
five interference bands. In
fact, it is unnecessary to set
interference boundary 0 and
interference boundary 5.
One of them represents
infinity and the other
represents negative infinity.
This parameter, describing
the remaining four
boundaries, is one of the
BTS configuration
parameters.
Generally, -85 dBm - -115
dBm is used for interference
boundaries 1 - 4.

Hello Sir,
For your Kind Reference only, please find below details as per required from ZTE Expert team:
1. Directed Retry is disabled in Ahmedabad ALIL BSC and we have used Fast HO instead. Fast HO
parameter mapping not shown in this sheet. Kindly ask what is used by ZTE for Fast HOset.
Name:drInd
2.Moreover, kindly get the RX level for uplink interference for bands 1 to 5. Receive sensitivity not
mentioned. Whether HR with AMR is supported and if yes how to implement it.
RX level for uplink interference for bands 0 to 7 (Counter list)
C901230027
C901230028
C901230029
C901230030
C901230031
C901230032
C901230033
C901230034
The percent of 1 to 5 is
(C901230028+C901230029+C901230030+C901230031+C901230032)/(C901230027+C901230028+C90123
0029+C901230030+C901230031+C901230032+C901230033+C901230034)
Receive sensitivity is
RxLevAccessMin 10 (-101~100)
HR is usually function , you should know how to open it
DynaHREnable
UseCellDynHRPara
3.What is the location update timer T3212 value from the network is set should also be seen form the OMCR
and what should be best value is to be taken from ZTE expert.
T3212 value 10 (360S)

Hello Sir,
Please find attached ZTE vs ALU Parameter Mapping with defaults values_GSM.
Example:
DRT (Direct Retrieved): ZTE Parameter Name_ "drind_0"
for 3G : "rrcrdtswch" ( suggest not to open as 3G can set at FACH channel when DCH is busy)
