Test Sequence CTS55
1094.0006.55 4.6 E-6
4.3 2nd Step - Location Update
The CTS sends the broadcast information on the control carrier (C0). If following a request the mobile is
switched on, it will attempt to synchronise to this carrier by performing a Location Update. Should the
synchronisation be successful, the CTS terminates this test step with "
9
" in the LocUpd box. If the
synchronisation does not take place within a given time, the test will be ended with a "f" in the LocUpd
box. All subsequent tests will be skipped and the whole test sequence is terminated because it is not
possible to continue without a Location Update.
Possible causes for "fail":
•
The network parameters MCC, MNC, NCC or LAC are wrong: see section 9.9.6 for information
on configuring the network parameters.
•
Missing or incorrect power supply or defective battery.
•
Switch-on button of mobile not actuated or faulty.
•
Missing or poor RF connection (attenuation to be considered).
•
No test SIM card, poor contact of SIM card or card reader of mobile faulty.
•
The control channel is disturbed by a strong base station (if necessary use R & S shielded
chamber).
In all the above cases the error message "Location Update not received" appears on the screen.
