Columns for Dedicated channel:
Notes:
• The parameters LAC and cell are presented as hexadecimal digits, the remaining 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
cannot be updated under certain conditions and therefore, are displayed as "-" (for conditions see also
). 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 channel (parameter chann) is not
stable. This mode is indicated by chann = 'h'.
• To some extent, the cell monitoring command
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.
