Location Update Location Update
determines in which cases the mobile performs a location update:
•
Always
each time the mobile station is switched on
•
Auto
only if required
A location update is normally used to signal to the base stations that the mobile station has
changed its position. In this case, it is used to report to the CMU that the mobile station is
switched on and ready for a call. After a location update of the mobile station, the signalling
state
Synchronized
is reached. The parameter
Auto
implies that the attach bit is cleared. The
mobile station will then only perform a location update if it does not seem to be registered.
This may happen when the SIM card is changed or when the network parameters (e.g.
location area
) are changed in the CMU.

Default IMSI
The
Default IMSI
section defines an international mobile subscriber identity (IMSI)
which is used to set up the call to the mobile
.
It consists of:
MCC
3-digit mobile country code
MNC
2-digit mobile network code (3-digit for GSM850 and GSM1900)
MSIN
10-digit mobile subscriber id. No. (9-digit for GSM850 and
GSM1900)
The IMSI of the mobile phone must be known before the call can be established. If
the IMSI is known and reported to the tester as
Default IMSI,
it doesn't have to be
determined during the location update; the call procedure will be faster. For this
purpose, the international mobile subscriber identity request must be switched off
(IMSI Request = Off).
Otherwise, the
Default IMSI
is overwritten by the respective parameters of the
mobile station as soon as these are requested and transferred. For this purpose,
the international mobile subscriber identity request must be switched on
(IMSI
Request = On).
The default setting for the
Default IMSI
is MCC = 001, MNC = 01,
MSIN = 1000000095 (Phase-2 mobile phones). For GSM850 and GSM1900,
MNC = 010, MSIN = 100000095.

Power Change
Mode
The
Power Change Mode
controls the power change of the mobile station:
Slow
Slow power change, controlled via SACCH
(slow associated
control channel),
Fast
fast power change, controlled via FACCH
(fast associated
control channel).
Note: The CMU does not check whether the new power has already been
achieved at the end of the command (be careful with remote-control
programs).
