Service States; At^monp Monitor Neighbor Cells - Multi-Tech MultiModem EDGE Reference Manual

8.10.2 Service States

Depending on the service state, an additional textual output is generated (refer also to the response examples):
•
'Searching' - The MS is searching, but could not (yet) find a suitable cell. This output appears after restart of the
MS or after loss of coverage.
•
'No connection' - The MS is camping on a cell and registered to the network. The service state is idle; i.e., there
is no connection established or a dedicated channel in use.
• 'Cell Reselection' - The MS has not yet lost coverage but is searching for a better cell, since the cell reselection
criterion is fulfilled.
•
'Limited Service' - The MS is camping on a cell but not registered to the network. Only emergency calls are
allowed. The MS enters this state, for example, when
∗ no SIM card is inserted, or PIN has not been given,
∗
neither Home PLMN nor any other allowed PLMN are found,
∗ registration request was not answered or denied by the network (use command AT+CREG to query the
registration status),
∗
authentication failed.

Parameter Description:
<period>
Display period in seconds
1...254
Notes:
•
Due to the fact that not all necessary information of the neighbor 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).
Multi-Tech Systems, Inc. AT Commands for EDGE Modems (S000371G)
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".
