8.3 AT^MONP Monitor neighbour cells

Test command

AT^MONP=?

Response

^MONP: (list of supported < period >s) OK

Write command

AT^MONP=[<period>]

This command can be used to retrieve information of up to six neighbour

cells automatically every n seconds. It is cancelled by any character sent

to the serial port except if autobauding is enabled (+IPR=0). Then type

character ´a´ to abort.

Response

See execute command

Parameter

<period> 1 – 254 Display period in seconds

Execute command

AT^MONP

This command can be used to obtain information of up to six neighbour

cells on request.

Response (Example)

Parameter:

Chann ARFCN (Absolute Frequency Channel Number) of the BCCH

carrier

rs RSSI value 0 – 63 (RSSI = Received signal strength indication)

dBm Receiving level in dBm

PLMN PLMN ID code

BCC Base Station colour code

C1 coefficient for base station selection

C2 coefficient for base station reselection

Reference

Siemens

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.
