). 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.

• For compatibility with earlier products and to support legacy applications, any input character may be used to
