GSM Idle Mode Parameter

Value
|
Remarks
|
ACCMIN
|
Minimum received signal level in dbm at the MS for
permission to access the system
|
47 to 110 dBm
|
- 110 dBm
|
A low value of ACCMIN means that the coverage in idle mode
is improved at the expense of the risk
of having an increased number of call setup failures. formula is C1 = (rxlev
−ACCMIN) −max (CCHPWR −P, 0)
|
CCHPWR
|
Maximum transceiver power level an MS may use when
accessinf on a control channel
|
13 to 43 (GSM900)
|
33
|
CCHPWR is the cell
parameter that indicates the maximum transmitting power that an MS is allowed
to use when accessing the system.
|
4 to 30 (GSM1800)
|
30
|

CRH
|
Cell Reselection Hysteresis - receiving signal strength
hysteresis
|
0 to 14 in steps of
2db
|
6
|
C1(N) > C1 + CRH ( this parameter is applicable for
location area boundary cell and for reducing of unwanted ping-pong
singnailing paging)
|
NCCPERM
|
PLMM (NCC) Permitted -
|
0 to 7
|
1, 4, 6
|
Up to 8 NCCs can be defined, defined the allow NCCs (Network Colour
Code) on the BCCH carriers for which
the MS is permitted to send measurement reports
|
CBA Or CB
|
Cell Bar Access Defines
whether the cell is barred for access or not.
NO: The cell is not barred for access.
YES : The cell is barred for access.
|
Yes, No
|
No
|
The CBA bit is a
parameter for the network operator to set. Usually all the cells are allowed
to be accessed by MS,
|
CBQ
|
Cell Bar Qualify
|
HIGH, LOW
|
HIGH
|
- HIGH: The cell has high priority; LOW: The cell has low
priority
|
CRO
|
Cell Reselection Offset - defines an offset to encourage
or discourage MSs to select the cell while it is camping on another cell, eg:
perforam a cell reselection
|
0 to 63 [0 dB to
126 dB in steps of 2 dB)
|
0
|
The setting of this parameter will only affect phase 2
MSs C2 = C1 + CRO − TO * H(PT − T)
for PT ≠ 31
C2 = C1 − CRO for PT = 31 |
TO
|
Temporary Offset - defines a negative offset applied to
CRO
|
0 to 7 [0 dB to
infinite dB in steps of 10 dB]
|
0
|
The setting of this parameter will only affect phase 2 MSs
|
PT
|
Penalty time - defines duration for which TO is applied
|
0 to 31 [0 sec to
620 sec in steps of 20 sec]
|
0
|
The setting of this parameter will only affect phase 2 MSs
|
T3212
|
Defines the time-out value that controls the location
updating procedure,
|
0 to 255 deci hours
[Infinite time out to 25.5 hours]
|
40
|
0= Infinite time , 1= 6 min and 2= 12min , …
|
ATT
|
attach- detach allow
|
Yes, No
|
YES
|
NO : MSs in the cell are not allowed to apply IMSI attach
and detach. YES: MSs in the cell should apply IMSI attach
and detach. ATT tells the MS if it is
allowed to apply IMSI attach and detach, i.e. if the MS is allowed to send a
message to the system every time it is turned on or off
|
MaxRet
|
Maximum retransmissions
|
1, 2, 4, 7
|
4
|
Defines maximum number of retransmissions an MS may do
when accessing the system on RACH.
|
ACC
|
Access Control Class
|
0 to 15, CLEAR
|
clear
|
Defines which access classes that are barred. Up to 16
access classes can be defined. Class 10 defines emergency call in the
cell. 0 to 9 : Access classes that are
barred.
10 : Emergency call not allowed for MSs belonging to classes 0 to 9. 11 to 15 : Access classes that are barred. & CLEAR: No access classes are barred. |
BA List
|
Absolute RF channel number for measurement on BCCH.
|
In idle mode are used for cell reselection and In active
mode are used for sending NBR data by sacch.
