If error is related to ME functionality:

+CME ERROR: <err>

Parameter

The output contains 9 values from a maximum of 7 base stations. The first base

station is the serving cell.

Values for one base station in output order:

MCC Mobile country code, 3 decimal digits, e.g. 232

Value 000: not decoded

MNC Mobile network code, 2 decimal digits, e.g. 03

Value 00: not decoded

LAC Location area code, 4 hexadecimal digits, e.g. 3010

Value 0000: not decoded

cell Cell ID, 4 hexadecimal digits, e.g. 4EAF

Value 0000: not decoded

BSIC Base station identity code, 2 decimal digits, e.g. 32

chann ARFCN (Absolute Frequency Channel Number) of the BCCH

carrier, decimal, e.g. 82.

Value 0: not decoded. In this case, all remaining parameters related

to the same channel are neither decoded. For example, a non-

existing cell appears as follows: 000,00,0000,0000,00,0,0,0,0

RSSI Received signal level 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.

C1 Coefficient for base station reselection, decimal, e.g. 30

C2 Coefficient for base station reselection, decimal, e.g. 30

Note

· In dedicated mode, the parameters C1 and C2 cannot be updated, and

therefore, should be ignored.

· To some extent, the cell monitoring commands AT^MONI, AT^MONP and

AT^SMONC cover the same parameters. The receiving level, for example,

can be queried with all three 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.
