Parameter
explanations
number of preferred cells
NPC = decimal number
With this parameter you define the maximum number of preferred cell identifiers
that the BSC sends to the MSC in the handover required message.
The values range from 1 to 16 preferred cell identifiers.
GSM macrocell threshold
GMAC = decimal number in steps of two
With this parameter you define the macrocell size by means of the maximum
transmission power of the MS in a GSM cell.
Issue 19-1 en

The values range from 5 to 39 dBm. If you set the parameter value at 5 dBm, the
division of cells into macrocells and microcells is not in use.
GSM microcell threshold
GMIC = decimal number in steps of two
With this parameter you define the microcell size by means of the maximum
transmission power of the MS in a GSM cell.
The values range from 5 to 39 dBm. If you set the parameter value at 39 dBm, the
division of cells into macrocells and microcells is not in use.
DCS macrocell threshold
DMAC = decimal number
With this parameter you define the macrocell size by means of the maximum
transmission power of the MS in a GSM 1800 or a GSM 1900 cell. If you set the
parameter value at 0 dBm, the division of cells into macrocells and microcells is
not in use.
The values are
for GSM 1800: 0...36 dBm with 2 dBm step
for GSM 1900: 0...32 dBm with 2 dBm step and 33 dBm with 1 dBm
DCS microcell threshold
DMIC = decimal number
With this parameter you define the microcell size by means of the maximum
transmission power of the MS in a GSM 1800 or a GSM 1900 cell. If you set the
parameter value at 36 dBm in GSM 1800 or 33 dBm in GSM 1900, the division
of cells into macrocells and microcells is not in use.
The values are
for GSM 1800: 0...36 dBm with 2 dBm step
for GSM 1900: 0...32 dBm with 2 dBm step and 33 dBm with 1 dBm
MS distance behaviour
With this parameter you define the executions allowed after the timing advance
has exceeded the threshold.
DN9813184
Issue 19-1 en

The value range is 0...60 and 255.
Parameter Value Explanation
DISB = 0 Release immediately.
1 1 second time to try handover, release if handover is unsuccessful.
2 2 seconds time to try handover, release if handover is unsuccessful.
...
60 60 seconds time to try handover, release if handover is
unsuccessful.
255 No release, only handover attempts.
BTS site battery backup forced HO timer <option>
TIM = decimal number
With this parameter you define the maximum time period during which handover
is attempted in TRXs if a mains power failure is detected in the BTS and the spare
power supply is being taken into use. After the defined period has elapsed,
remaining calls are force-released. This is done in order to make the battery last
longer during power cuts.
The values range from 1 to 500 seconds.
enable emergency call on FACCH
With this parameter you enable or disable the emergency call setup on FACCH.
The emergency call setup on FACCH is possible only in those cells in which the
emergency call is not restricted (BTS level parameter EC). The FACCH call setup
is only possible when SDCCH congestion occurs.
The values are:
EEF = Y Enable emergency call setup on FACCH.
N Disable emergency call setup on FACCH.
enable answer to paging call on FACCH <option>
With this parameter you enable or disable an answer to the paging call setup on
FACCH. The FACCH call setup is only possible when SDCCH congestion
occurs. The values are:
Issue 19-1 en

EPF = Y Enable answer to paging call setup on FACCH.
N Disable answer to paging call setup on FACCH.
enable ordinary calls on FACCH <option>
With this parameter you enable or disable the ordinary call setup on FACCH. The
FACCH call setup is only possible when SDCCH congestion occurs. The values
are:
EOF = Y Enable ordinary calls setup on FACCH.
N Disable ordinary calls setup on FACCH.
enable call re-establishment on FACCH <option>
With this parameter you enable or disable the call re-establishment setup on
FACCH. The call re-establishment setup on FACCH is possible only in those
cells in which the call re-establishment (BTS level parameter RE) is allowed. The
FACCH call setup is only possible when SDCCH congestion occurs. The values
are:
ERF = Y Enable call re-establishment setup on FACCH.
N Disable call re-establishment setup on FACCH.
TCH in handover <option>
HRI = decimal number
With this parameter you define the traffic channel allocation during BSS internal
or external handovers. The parameter controls the target cell selection and the
TCH channel rate and speech codec determination in traffic channel allocation.
The values are:
HRI = 1 The call serving type of TCH has to be allocated primarily. The call
serving type of speech codec inside the call serving type of TCH can
change.
DN9813184
Issue 19-1 en

2 Primary allocation is preferred for the call serving type of TCH and the
call serving type of speech codec during the speech connection. The
channel rate change is possible during data connection, if necessary,
and if the radio interface data rate allows it.
3 The channel rate and speech codec changes are denied totally.
4 The preferred channel rate of TCH and preferred speech codec have
to be primarily allocated.
5 TCH has to be allocated primarily from the best BTS of the handover
candidate list.
lower limit for FR TCH resources <option>
HRL = decimal number
With this parameter you define the lower limit for the percentage of free full rate
resources. Full rate TCHs are allocated until the number of free full rate resources
is reduced below the value of the parameter. The half rate resources are then
allocated.
The parameter controls the TCH channel rate determination on the BSC level
according to the cell load in traffic channel allocation.
The values range from 0 to 100 %.
Parameters HRL and HRU can have the same values and effects as the BTS
object parameters FRL and FRU. When the BTS level parameters FRL and FRU
have reasonable values (FRL is equal to or smaller than FRU), the BSC level
parameters are not significant in TCH allocation. Otherwise the control of the
BSC object parameters will be followed. The cell load control will be applied
only if the preferred TCH channel rate is given by MSC.
During optional Half Rate, the parameter controls the TCH channel rate
determination on BSC level according to the cell load in traffic channel
allocation. Full rate TCHs are allocated until the number of free full rate resources
is reduced below the value of the parameter. After that half rate resources are
allocated. During optional Adaptive Multi Rate (AMR) Speech Codec the
parameter controls the packing of FR AMR calls to HR calls on BSC level
according to the cell load. Packing is done via an intra-cell handover. Packing is
active when the number of free full rate resources is reduced below the value of
the parameter and is actually triggered by a new channel allocation for BSC. The
principle in packing is that the number of free full rate resources increases by one
compared to the situation before the new channel allocation.
upper limit for FR TCH resources <option>
Issue 19-1 en

HRU = decimal number
With this parameter you define the upper limit for the percentage of free full rate
resources. Full rate TCHs are allocated when the number of free full rate
resources exceeds the value of the parameter.
The parameter controls the TCH channel rate determination on the BSC level
according to the cell load in traffic channel allocation.
Parameters HRL and HRU can have the same values and effects as the BTS
object parameters FRL and FRU. When the BTS level parameters FRL and FRU
have reasonable values (FRL is equal to or smaller than FRU), the BSC level
parameters are not significant in TCH allocation. Otherwise the control of the
BSC object parameters will be followed. The cell load control will be applied
only if the preferred TCH channel rate is given by MSC.
During optional Half Rate, the parameter controls the TCH channel rate
determination on BSC level according to the cell load in traffic channel
allocation. Full rate TCHs are allocated when the number of free full rate
resources increases above the value of the parameter. During optional AMR the
parameter controls the packing of FR AMR calls to HR calls on BSC level
according to the cell load. Packing becomes inactive when the number of free full
rate resources increases above the value of the parameter.
BSC call number <option>
BCN = decimal number
With this parameter you define the BSC ISDN call number. The values range
from 0000 to 999999999999999 (from four to 15 digits).
AMH upper load threshold <option>
AUT = decimal number
With this advanced multilayer handling parameter you define the upper threshold
for the load of the base station. The parameter is used to trigger BSC-controlled
traffic reason handovers.
DN9813184
Issue 19-1 en

Note
If a cell level parameter has some other value than N, it replaces the
corresponding BSC-level parameter.
AMH lower load threshold <option>
ALT = decimal number
With this parameter you define the lower threshold for the load of the base
station. The parameter is used to trigger advanced multilayer handling
functionality with IUO and/or Dual Band/microcell SW products.
Note
AMH max load of target cell <option>
AML = decimal number
With this advanced multilayer handling parameter you define the maximum
traffic load in the adjacent cell allowed for a target cell of traffic reason handover
(TRHO).
Note
AMR configuration in handovers <option>
With this parameter you define the preference between the currently used
multirate configuration and the one defined for the target BTS during internal and
external handovers. The values are:
Issue 19-1 en

ACH = 1 The currently used multirate configuration is preferred in further
channel allocations.
2 The multirate configuration of the target BTS is preferred in further
channel allocations.
initial AMR channel rate <option>
With this parameter you define the initial channel in call setup, internal inter–cell
handover (HO) and external HO for an Adaptive Multi Rate (AMR) call. The
values are:
IAC = 1 Any Rate, there are not any extra requirements for the parameter
and the chosen channel rate is defined by taking into account the
currently used information for channel allocation.
2 AMR FR is allocated despite of the values of the currently used
information for channel allocation.
slow AMR LA enabled <option>
With this parameter you define the AMR link adaptation (LA) mode within the
BSS. Alternatives are fast LA or slow LA. During the fast LA mode the BTS
allows the inband codec mode changes on every other TCH frame whereas during
the slow LA mode the BTS allows inband codec mode changes only on SACCH
frame interval. The values are:
SAL = Y Enable slow AMR LA mode
N Fast LA mode is used
AMR set grades enabled <option>
With this parameter you define whether the codec mode set downgrades are
applied or not during internal HOs and whether upgrades are applied or not after
internal HOs. The source side downgrade is used to align the source side codec
set with the one chosen for the target side in order to utilize the uni-directional
downlink connection for the target side. The utilization of the uni-directional
downlink connection decreases the amount of muting experienced in the speech
path connection during the internal HO. The target side upgrade is done to utilize
that original AMR codec set of the target BTS which was not chosen for the
target side because of the target side alignment with the source side during
internal HO. The reason for this alignment is the same as in the downgrade case.
DN9813184
Issue 19-1 en

ASG = Y Downgrades and upgrades are applied
N Downgrades and upgrades are not applied
free TSL for CS downgrade <option>
CSD = decimal number
With this parameter you define a safety margin for the circuit switched traffic. If
the number of free TSL(s) in a BTS becomes less than the margin defined by the
parameter then a GPRS downgrade is started.
The values range from 0 to 100 %. Value 0 % means that no GPRS downgrade is
done to maintain a safety margin.
free TSL for CS upgrade <option>
CSU = decimal number
With this parameter you define a safety margin for the circuit switched traffic.
This margin is examined when deciding if a GPRS upgrade is allowed in a BTS.
A GPRS upgrade may be done if the number of free TSLs in a BTS will still be at
least the margin defined by the parameter after the upgrade. Actually the
parameter states how many seconds after an upgrade the probability for a GPRS
downgrade should be no more than 5 %. The BSC defines the number of TSLs
for the safety margin according to the given time and the number of TRXs in the
BTS.
The values range from 0 to 10 s. Value 0 means that no margin is maintained in
GPRS upgrade.
TRHO guard time
TGT = decimal number
With this parameter you define the guard time after a BSC-controlled or an MSC-
controlled TRHO, during which a handover back to the original cell is not
allowed.
The values range from 0 to 120 s.
Issue 19-1 en

Note
HO preference order interference DL
With this parameter you define the order of preference between intra-cell and
inter-cell handovers when the cause of the handover is downlink interference.
The values are:
HDL = INTER The inter-cell handover has greater priority.
INTRA The intra-cell handover has greater priority.
HO preference order interference UL
With this parameter you define the order of preference between intra-cell and
inter-cell handovers when the cause of the handover is uplink interference. The
values are:
HUL = INTER The inter-cell handover has greater priority.
INTRA The intra-cell handover has greater priority.
load rate for channel search
CLR = decimal number
With this parameter you define the general load limit for traffic channels in a cell
under the BSC. If the TCH load in a cell is below the limit, the traffic channels for
speech and single slot data calls are allocated using rotation between TRXs in a
cell and between TSLs of a TRX. If the load limit has been reached or exceeded,
the TCH allocation is performed trying to save larger spaces of idle FR resources
for the possible multislot HSCSD calls by preferring small gaps of free resources
and ends of a TRX for single slot calls.
If the BTS-specific parameter cell load for channel search has been set (the value
is not 0) in a BTS, this will override the effect of the BSC level parameter in that
BTS.
DN9813184
Issue 19-1 en

triggering threshold for service area penalty <option>
TTSAP = decimal number
With this parameter you define the triggering level for a Service Area penalty.
The Service Area-specific penalty timer is triggered if the number of incoming
Inter-System handovers occurring from a certain Service Area exceed the penalty
triggering level during a measurement period. While the Service Area penalty
timer is on, the BSC is not allowed to initiate an Inter-System handover attempt
towards WCDMA RAN cells which belong to the Service Area.
The values range from 0 to 255.
penalty trigger measurement period <option>
PTMP = decimal number
With this parameter you define the length of the period during which the latest
Inter-System handover counters are used, if the WCDMA RAN Service Area and
neighbour WCDMA RAN cell penalty triggering are used. According to the
value of this parameter, the BSC calculates the number of successful incoming
Inter-System handovers per each Service Area and the number of unsuccessful
outgoing Inter-System handover attempts per each neighbour WCDMA RAN cell
during the latest measurement period. The values are N, and 2...254 with 2 s
steps. The value N means that WCDMA RAN Service Area and neighbour
WCDMA RAN cell penalty triggering is disabled in the BSC.
service area penalty time <option>
SAPT = decimal number
With this parameter you define the duration of the handover penalty timer which
has been triggered for a Service Area. While the Service Area penalty timer is on,
the BSC is not allowed to initiate an Inter-System handover attempt towards
WCDMA RAN cells that belong to the Service Area.
CS TCH allocate RTSL0 <option>
CTR = decimal number
With this parameter you define the priority order between GPRS and RTSL-0
allocation. With the parameter you can define the RTSL-0s to be allocated before
allocating a TCH from GPRS territory.

The values are:
CTR = N The GPRS territory is allocated
first. If no free resources are
available then the RTSL-0 hopping
group is searched.
Y The RTSL-0 hopping group is
allocated first. If no free resources
are available then the GPRS
territory is searched.
CS TCH allocation calculation <option>
CTC = decimal number
With this parameter you define how the GPRS territory is seen when calculating
FR resources.

there have been enough calls during the measurement period (the number of
seizures is greater than or equals to the operator-defined threshold value), the
alarm system prints out an alarm.
The value has to be lower than the value of the parameter maximum mean
holding time for TCHs.
Note
The value range of minimum mean holding time for TCHs is in seconds and
the value range of maximum mean holding time for TCHs is in minutes.
maximum mean holding time for TCHs
MAXHTT = decimal number
With this parameter you define the maximum mean holding time for traffic
channels. If the mean holding time during a measurement period is greater than or
equal to the maximum mean holding time, the alarm system prints out an alarm.
The values range from 0 to 1440 minutes (=24 hours).
The value has to be higher than the value of the parameter minimum mean
holding time for TCHs.
Note
The value range of minimum mean holding time for TCHs is in seconds and

alarm threshold for TCH failure rate
TCHFR = decimal number
With this parameter you define an alarm threshold for traffic channel failure rate.
Whenever a channel is released with a release cause other than a normal one, the
counter of channel failures for the released channel is incremented. If the
percentage of channel failures equals to or exceeds the threshold and there have
been enough calls during the measurement period (the number of seizures is
greater than or equal to the operator-defined threshold value), the alarm system
prints out an alarm.
alarm threshold for SDCCH failure rate
SCHFR = decimal number
