If your UE does not register with the test set, you may need to:
Set
, and then turn the UE's power off and on. To determine
whether to camp to a cell, the UE measures the CPICH RSCP for
the cell, and then compares it to the minimum CPICH RSCP required
to camp to the cell (the test set specifies a minimum CPICH RSCP
of -115 dBm). If the UE's maximum transmit power is less than
the Maximum
Uplink Transmit Power Level specified by the test set, then
the UE must subtract this difference from it's CPICH RSCP value
before comparing it to the minimum requirement of -115 dBm. For
example, if Maximum Uplink Transmit
Power Level is set to +33 dBm, the UE's maximum transmit
power is +24 dBm, and the UE measures a CPICH RSCP of -111 dBm,
then it will not camp to the test set (-111 dBm - (33 dBm - 24
dBm) = -120 dBm, which is less than the minimum required level
of -115 dBm). If Maximum Uplink Transmit
Power Level were set to +24 dBm, then the UE would camp
to the test set (-111 dBm is greater than the minimum required
level of -115 dBm). To ensure that your UE will camp to the test
set at low cell power levels, set
Maximum Uplink Transmit Power Level to the maximum transmit
power for your UE.
If Call Limit State is set to On and you page the UE, the test set will not respond to the UE's PRACH sequence. If the UE reaches the end of its sequence without an acknowledgment from the test set, it may place the test set into its cell barred list. (This may need to occur several times before the UE places the test set into its cell barred list). This means the UE will not look for the test set on its next attempt to camp to a base station. (After a certain amount of time, the UE will resume its consideration of the test set when trying to camp to a base station). If the test set has been added to the UE's cell barred list, you may need to:
If the UE expects integrity protection to be enabled then it will continually attempt to register (as often as every 30 seconds) until the location update procedure successfully starts integrity protection. For integrity protection to be successfully started, the Security Operations setting must be 'Auth+Int' and the rest of the parameters on the Security Settings menu (excluding 'RAND') must match those in the uSIM. See Security Information .
To successfully establish a call, you may need to:
Off .
Initialise . Note, most UEs do not require that this
parameter be changed from its default value of
Maintain . Some UEs may not connect to the test set
if this parameter is set to Initialise
. Also note that call establishment times will increase when
RB Setup Timing Indication (CFN Handling) is set to
Initialise .This section is only applicable to the lab application or feature-licensed test application.
To successfully establish an HSDPA connection, you may need to:
Off .
On .
CN Domain set to PS Domain
or CS/PS Domain
), the UE must have attached to the test set. To enable this,
the PS
Domain Information parameter must have been set to Present when the UE registered
with the test set. Note that
PS Domain Information is set to
Absent by default in the Test Application (it is set
to Present by default
in the Lab Application). 12.2k RMC + HSDPA .This section is only applicable to the lab application or feature-licensed test application.
To successfully establish an HSPA connection, you may need to:
Off . Present
before the UE registers with the test set (
PS Domain Information is set to
Absent by default in the Test Application and to Present by default in the Lab
Application). 12.2k RMC + HSPA
.If your UE registers with the test set, but does not respond to the test set's page, try this alternate (and usually faster) test set-originated connection procedure:
Operating Mode to Cell Off . Repeat Paging to
On . ATT (IMSI Attach) Flag State to Set . Operating Mode to Active Cell . Originate Call and power
on the UE.After the UE registers with the test set (performs a Location Update), rather than releasing the RRC connection, it will immediately move to connecting the RB test mode call as there is a page request outstanding.
TMSI , the UE must have a TMSI assigned to it before
it will respond to the test set's page. The test set assigns
a TMSI to the UE during the Location Update Procedure if TMSI
Assignment is set to On
before the Location Update Procedure is performed. The TMSI
being used to page the UE must be the same as the TMSI assigned
to it during registration (the TMSI
setting must not have been changed between registration and
paging). RB Test Mode call, you
must set Paging Service to RB Test Mode and originate the
call from the test set. You can not originate an
RB Test Mode call from the UE.
PS Domain Information is set to
Present . If so, before establishing an
RB Test Mode or AMR Voice
call, you must first select
End Call .
To aid in successful call completion, ensure that your UE does not begin its PRACH preamble sequence at the Maximum Uplink Transmit Power Level or its maximum transmit power (the maximum power it is physically able to transmit). If the UE supports early termination of the PRACH procedure, it will terminate the PRACH preamble sequence once it reaches the maximum transmit level for the cell (as specified by Maximum Uplink Transmit Power Level ) or is maximum transmit power. If a UE supporting early termination begins its PRACH transmission at either of these maximum levels, it will only transmit one PRACH preamble, causing the call setup procedure to fail (the test set requires two consecutive preambles before it will issue a positive indication on the AICH). See Initial PRACH TX Power .
E-DCH RLC SDU Size to at least 4 x 2936 bits = 11744 bits.
Note that you must also set RB Test
Mode E-DPDCH Max Channel Codes =
2SF2 , grant the UE a large enough serving grant to allow
this data rate, and ensure that the UE's transmit power is low
enough that the HSUPA channels do not get scaled down.
Throughput = 0 kbps, initiate the Single
Shot AG action and observe if throughput then becomes non-zero.
There is a known issue in some UEs wherein they ignore the RB
Setup AG value and use a zero grant upon call establishment. On (they are
both set to off by default). Off
(see Downlink
Channel Levels Overview ), the test set will
not automatically turn it back on if it is needed to perform
a call processing operation you've requested (for example, if
you set PICH Level to Off , the
Originate Call procedure will fail).
