GPIB Command Conventions

CALL:HANDover|HANDoff[:IMMediate]

Function

GSM TA

This command applies to GSM as described in the GPRS description. This command applies the deferred TCHannel parameters to the active TCH. These parameters are:

  • Deferred TCH Timeslot
  • Deferred mobile station TCH TX level [band]
  • Deferred TCH ARFCN [band]
  • Deferred TCH band
  • Deferred TCH channel mode (full-rate, enhanced full-rate, or half-rate speech)
  • Deferred TCH channel mode half-rate speech sub channel
For more information on the use of deferred parameters see Using Deferred Parameters .

GPRS TA


This command applies the deferred PDTCH parameters to the active PDTCH. These parameters are:

  • Deferred PDTCH Band
  • Deferred PDTCH ARFCN [band]
  • Deferred mobile station TX Level [burst][band]
  • Deferred Multislot Configuration
  • Deferred Coding Scheme
  • Deferred P0

For more information on the use of deferred parameters see Using Deferred Parameters .

The action taken when this command is set depends on the setting of the cell operating mode and the data connection status:

  • When the cell operating mode is set to Active Cell (see CALL:OPERating:MODE ) and the data connection status is Transferring, this command causes any necessary over-the-air signaling to modify the PDTCH resources (frequency, power level, timeslot assignment and coding scheme). The immediate settings are updated with the deferred settings just applied and the current downlink PDTCH levels are updated.
  • When the cell operating mode is set to Active Cell (see CALL:OPERating:MODE ) and the data connection status is any state other than Transferring, the handover command is ignored and the following error is displayed "Call operation rejected; Protocol request ignored." The immediate settings are not updated.
  • When the cell operating mode is not set to Active Cell, this command replaces any active PDTCHs with new PDTCHs using the new parameters. If there are no active PDTCHs, the new values will be remembered until there is an active PDTCH. In either case, the immediate settings are updated with the deferred settings just applied and the current downlink PDTCH levels are updated.

This command initiates the network initiated handovers and cell reselections in the two cell test system.

The type of cell transition performed by the test set upon receipt of this command depends on the current connection status of DUT. If a voice, CSD or DTM session is currently in progress. a "Handover command" message is sent to the DUT requesting it performs a Handover. If the DUT is in Idle mode (but at least GPRS attached) or a GPRS /EGPRS data connection is in progress, a Packet Cell Change Order message is sent to the DUT requesting it perform cell reselection.

see Two-Cell Test System for more information.

This command sets/quires the Report Observed Time Difference (ROT) state. When the ROT state is set to ON, the Timing Difference IE is present in the HANDOVER_COMMAND message.

The Timing Difference value is controlled by the timing advance values in the two test sets of the two-cell test system:

TD = (2k+TA[A]-TA[B])mod 256

Where:
              TD = Timing Difference
              k = an arbitrary bit offset value by which the frames in the slave test set
                  lead the frames in the master test set.
              TA[A] = Timing Advance on the slave test set.
              TA[B] = Timing Advance on the master test set.
