8.9 AT^MONP Monitor Neighbour Cells
Description: The AT^MONP supplies information for up to six neighbor cells. There are two ways to
retrieve the information: 1) by request using the execute command or 2) automatically
every <period> seconds by using the write command. To stop the periodic presentation
type “AT” or “at”.
Test Command Syntax: AT^MONP=?
Response: ^MONP:(list of supported <period>s)
OK
Exec Command Syntax: AT^MONP
Response: See: Section 8.8.1, AT^MONP responses
OK
Write Command Syntax: AT^MONP=<period>
Response: See: Section 8.8.1, AT^MONP responses
OK
ERROR
+CME ERROR
Parameter Description:
<period>
Display period in seconds
1...254
Notes:
• 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 neighbor 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 neighbor 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.
∗ To some extent, the cell monitoring command AT^SMONC covers the same parameters. The receiving
level, for example, can be queried with both commands. Yet the resulting values may be slightly different,
even though obtained over a time period of a few seconds. This is quite normal and nothing to worry about,
as the cell information is permanently updated.
• For compatibility with earlier products and to support legacy applications, any input character may be used to
stop the output in certain cases (depending on the settings of AT+IPR and AT+CMUX).
