At^monp Monitor Neighbour Cells - Siemens TC37 Module At Command Reference

AT Command Set

6.3 AT^MONP Monitor neighbour cells

Test command
AT^MONP=?
Write command
AT^MONP=[<period>]
Execute command
AT^MONP
Reference
Siemens
TC3X_ATC_01_V04.00
Response
^MONP: (list of supported < period >s) OK
This command can be used to retrieve, automatically every n seconds,
information of up to six neighbour cells. The display can be terminated by
any character sent to the serial port except if autobauding is enabled
(+IPR=0). In this case, type character ´a´ to abort.
Response
See execute command
Parameter
1 – 254
<period>
This command can be used to obtain, on request, information of up to six
neighbour cells.
Response (Example)
Parameter:
Chann ARFCN (Absolute Frequency Channel Number) of the BCCH
carrier
rs RSSI (Received signal strength) of the BCCH carrier, decimal
value from 0 to 63. The indicated value is composed of the
measured value in dBm plus an offset. This is in accordance with
a formula specified in 3GPP TS 05.08.
dBm receiving level in dBm
PLMN ID code
PLMN
BCC base station colour code
C1 coefficient for base station selection
C2 coefficient for base station reselection
Note
· Cell information can be issued in the form of unsolicited result codes
(related to <period>), or it can be queried directly using the Execute
command AT^MONI. In the first case, the ME activates its RING line
(Logic "1") for one second to send the URC to the connected applica-
tion. In the second case, the RING line does not change.
· Due to the fact that not all necessary information of the neighbour cells
can be decoded during a connection, there are several constraints to
be considered:
Only neighbour cells that have already been visible in IDLE mode
-
will be further updated, as long as they are still included in the list.
Though new neighbour cells can be added to the list (e.g. due to
-
handover), their C1 and C2 parameters cannot be displayed until
the connection is released. In this case "-" is presented for C1 and
C2.
· The list does not include the serving cell.
· Further cell information can be obtained with AT^SMONC (see Chapter
6.17).
