When the test set orders a Physical Channel Reconfiguration, it takes a finite amount of time for the test set to move to and settle at the new frequency. When the Physical Channel Reconfiguration is ordered, most UEs wait a time of T312 at the new frequency before determining that the handover has failed (T312 is signalled by the test set in SIB1 with a value of 5 seconds). If your UE does not wait once moving to the new frequency, the handover may fail. If it does, set
PCR Activation Time
as needed to cause the UE to wait until the test set has moved to the new frequency (a setting of 100 (100 x 10 ms = 1 s) is usually sufficient). Do not set
PCR Activation Time
to a value other than 0 unless necessary, as it slows down the handover procedure.
DL Channel
of
10700
and default handover downlink channel of
10730
are 6 MHz apart (the default uplink channels are also 6 MHz apart). If you wish to handover to channels that are 5 MHz from the default channels, set the handover downlink channel
to
10725
and handover uplink channel to
9775
.The Transport Channel Reconfiguration provides three main functions:
Initialise
(or set to
Auto
and
TCR Default DPCH Offset (DOFF)
is set to a value other than the
Current DPCH Offset
), and the handover downlink and uplink channels are the same as the current downlink and uplink channels, the UE may drop the call, ignore or reject the reconfiguration request, or report a reconfiguration failure.

.This functionality is only available in GSM/GPRS_W-CDMA fast switching test and lab applications.
The system handover functionality allows you to handover to a GSM voice call from any of the following connection types:
CS Domain
(
lab application or feature licensed test application only
)You must be on one of these types of connections to perform a system handover.
Active Cell
operating mode.
On
, the UE will ring. You must answer the ring for the connection to be completed and testing to progress.
Off
, when the handover is completed, the connection is left in the RR Connected state. Data loopback (for BER testing) is available in this state, but voice echo is not.
Off
. Otherwise, the test set will not continue with the handover until it receives the expected acknowledgment, and the handover will fail.
System Handover

System Handover
parameter settings are not saved when using the
SAVE REGISTERS
utility.
