Reference Note
· The parameters LAC and cell are presented as hexadecimal digits, the remain-
Siemens
ing 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, there-
fore, are left blank (see also +CREG, pg 123). This is because the ME does not
update the cell selection and reselection parameters since, in this mode, they
are not relevant for operation. When the connections ends, and the ME is back
to IDLE mode, both parameters will be updated.
If the radio cell changes during a connection, it normally takes 1 or 2 seconds
to update the parameter cell. Until the Cell ID is received from the new base
station, the default value 0000 will be shown instead.
· 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'.
· The cell information can be issued in the form of unsolicited result codes (re-
lated 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.
