Active Cell Operating Mode
Active Cell Operating Mode
April 20, 1999
The test set can operate in two different operating modes (active cell mode or test mode). The operating modes
changes the way in which the test set interacts with the mobile station. Active cell mode is the default
operating mode and is used when emulating a normal GSM cell. Test mode is used when it is not possible, or
not desired, to communicate via over the-the-air signaling with the mobile station (MS), but downlink
stimulus and uplink measurements are still needed. see "Test Mode Operating Mode" on page 524
Associated with the active cell operating mode is the cell activated state parameter. This parameter turns on
and off the test set's control of the uplink and downlink.
Trying to set any of the network configuration parameters while the cell is in the active state will generate the
following error:
GSM operation rejected; Attempting to set <MCC|MNC|LAC|NCC|BCC> while generating a BCH
Active Cell Features
The basic features provided by active cell operating mode are:
• Generation of a broadcast channel (BCH) without traffic channel (TCH).
• Support for location updating.
• Call setup, both mobile station and base station emulator (BSE) originated.
• Changing TCH parameters during a call using over-the-air signaling.
• BSE initiated and mobile station initiated call disconnection.
• All measurements supported in the test application are available.
• The BSE automatically controls the test set's demodulation receiver.
Setting the Test Set's Operating Mode to Active Cell Mode
The test set's operating mode is set using the CALL:OPERating:MODE, which is a sequential command.
Example 4. Command Syntax:
CALL:OPERating:MODE <CELL|TEST>
