Reference Note
· The parameters LAC and cell are presented as hexadecimal digits, the
Siemens
remaining parameters are composed of decimal digits.
· If the radio cell changes during a connection, the parameters PWR and RXLev
of the 'Serving Cell' part cannot be updated under certain conditions and,
therefore, are left blank (see also +CREG, pg 107). This is because the MS
does not update the cell selection and reselection parameters since, in this
mode, they are not relevant for operation.
· If the BS supports frequency hopping during a connection, the dedicated
channel (parameter chann) is not stable. This mode is indicated by chann = 'h'.
· The 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 application. In the second case, the
RING line does not change.
· 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.
