Step 7: Perform an Intra-Cell Handover
Example 1. Command Syntax:
CALL:TCHannel[:ARFCn][:SELected]:SEQ <numeric value>
OR
CALL:TCHannel[:ARFCn]:<PGSM|EGSM|DCS|PCS>:SEQ <numeric value>
Example 2. Programming Example:
The following example illustrates how to use these commands to perform an intra-cell handover.
! existing conditions: a mobile station is connected to the test
! set, operating mode is set to active cell and a call is in the
! connected state.
! Step 1: Change the traffic channel number
OUTPUT Test_set;”CALL:TCH:SEQ 65”!Starts process of handing over MS
!to new traffic channel 65.
!No other commands will be processed
!until this operation completes
!because the :SEQ has been attached.
! Step #2: Check that the call is still in the connected state. It
! is possible that the MS did not successfully connect on the
! new channel.
OUTPUT Test_set;”CALL:STAT:STAT?”
ENTER Test_set;Call_status$
IF Call_status$ <> “CONN” THEN
! <put error handler here>
END IF
! Call is connected so proceed with control program
Performing a Dual-Band Handover
A dual-band handover is accomplished using the CALL:TCHannel:BAND command. The recommended
process for performing a dual band handover is shown in the following figure.
