The following parameters are provided to define the contents of the downlink signal to the UE (mobile station) while the call is connected, and to control the call connection behavior. To access these parameters from the front panel, see How Do I Change Call Parameters? .
The data pattern of the DTCH data (user data) sent on the DPCH can be set to:
When on an HSDPA or HSPA RB test mode connection (see
HSDPA RMCs
and
HSPA RMCs
), the
DL DTCH Data
setting only configures the data on the RMC portion of the channel. To configure the data being sent on the FRC, use the
HS-DSCH Data Pattern
setting (
lab application or feature-licensed test application only
).
The RB Setup message that establishes the Radio Access Bearers (RABs) may specify a DCCH RLC Block Size that differs from the DCCH RLC Block Size that was being used when only a Signalling Radio Bearer (SRB) was present. If the RB Setup message specifies a change in the DCCH RLC block size from the stand-alone SRB configuration, the UE and network must change the DCCH RLC block size and then perform an RLC Re-establishment procedure to reset the RLC buffers (see 3GPP TS 25.322 9.7.7).
If your UE does not support changing DCCH RLC block size during connection setup and the RB Setup specifies a change in the DCCH RLC block size, the connection attempt will fail (to avoid this, you must establish the call using an SRB with a DCCH RLC block size that is equal to the DCCH RLC block size defined for the service you wish to establish, see Signalling Radio Bearer (SRB) Parameters ).
If your UE supports changing DCCH RLC block size during connection setup, but does not support the RLC Re-establishment procedure, you must either use an SRB that matches your desired service as explained above, or set
RLC Reestablish
to
Off
.
RLC Reestablish
is set to
Off
, the test set does not perform the RLC Re-establishment procedure. If your UE supports changing DCCH RLC block size during connection setup, the DCCH RLC Block Size is changed even if the RLC Re-establishment is not performed. However, some signalling data may be lost if the block size is changed without an RLC Re-establishment procedure.
RLC Reestablish
is set to
On
, if the RB Setup specifies a change in the DCCH RLC block size, the test set performs the RLC Re-establishment procedure.When the call limit state is on, the test set does not respond to any PRACH preambles from the UE. Call Limit must be OFF for any random access procedure, such as Location Update or BS Origination to be successful (see Establishing a Connection with the UE ).
Once the random access procedure has been initiated with Call Limit set to "ON", the Test Set will appear to be "hung" indefinitely. You must end the call to terminate the procedure and return the Call Status to "IDLE". (See How Do I End a Connection? or CALL:END .)
The call drop timer can be turned off or on. When turned on, anytime the uplink signal is not detected, the test set only waits the length of the timer before assuming the call has been dropped by the UE. This timer is optimized for the manufacturing test environment. The timers defined in the 3GPP standards for determining that a call has been dropped are much longer. Turning on the call drop timer allows you to quickly identify UEs that can not maintain a call and remove them from your test area.
