Note
· The parameters LAC and cell are presented as hexadecimal digits, the remain-
ing parameters are composed of decimal digits.
· If the radio cell changes during a connection, the parameters PWR, RXLev and
C1 of the ‘Serving Cell’ part are not available under certain conditions and
therefore, are displayed as “-“ (for conditions see also +CREG, pg 141). This is
because the MS does not update the cell selection and reselection parameters
since, in this mode, they are not relevant for operation. When the connection
ends, and the mobile is back to IDLE mode, correct values will be given.
If the radio cell changes during a connection, it normally takes 1 or 2 seconds
to update the parameters cell, NCC and BCC. Until the information is received
from the new base station, the default values will be shown instead:
cell=”0000”, NCC=”-“, BCC=”-“.
· If the BS supports frequency hopping during a connection, the dedicated chan-
nel (parameter chann) is not stable. This mode is indicated by chann = ‘h’.
· To some extent, the cell monitoring command AT^SMONC covers the same
parameters. The receiving level, for example, can be queried with both com-
mands. 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.
