Configuring Mobile Station Operating Parameters

Last updated: December 2, 2008

The mobile station operating parameters are configured using the following call processing subsystem commands.

For a complete list of GPIB commands in the call processing subsystem, refer to CALL Subsystem .

GSM Mobile Station Operating Parameters


Parameter	GPIB Command
IMSI Attach Flag State	CALL:IATTach
Maximum Control Channel Power	CALL[:CELL]:MS:TXLevel:CCHannel[:SELected]
Defines an additional offset value used to increase the Max CCHannel value for DCS band only	CALL[:CELL]:MS:CCHannel:POWer:OFFSet:DCS
Mobile DTX State	CALL:MS:DTX[:STATe]
Mobile station TX Level	CALL:MS:TXLevel[:SELected]
Timing Advance	CALL:MS:TADVance[:SELected]

GPRS and EGPRS Mobile Station Operating Parameters

Operating Considerations

GSM

There are a number of parameters for the broadcast channel (see Configuring the Broadcast Channel (BCH) ) and the traffic channel (see Configuring the Traffic Channel (TCH) Parameters ) that can be configured, however the test set's default parameters should allow a properly functioning mobile station to successfully camp on the cell and make a call under most circumstances.

When Operating Mode = Active Cell, if a call is connected, changes to these parameters, including a change to the value of the parameter's current setting, causes signaling on the downlink to automatically initiate the change. No separate command is necessary to initiate the change. If a call is not connected, changes to the parameter are stored for when the next call is established

GPRS and EGPRS
