Step 2: Configure Test Set and UE Parameters

Last updated: January 16, 2009

In this step you configure the parameters that allow a connection to be made between the test set and UE.

Set up the Cell Parameters

The example below illustrates how to set up the cell parameters. You can set cell parameters like the MCC, MNC, and LAC as well as specify whether single or repeat paging should be used when paging the UE.

The operating mode must be Cell Off to set up the cell parameters. See Set Operating Mode . If you do not set the operating mode to Cell Off, the test set generates the following error:

Command Rejected. Change Not Allowed in Active Cell Mode.

 
320   ! Cell Parameters
330   OUTPUT Testset;"CALL:LAC 30865" !Correct LAC avoids Location Update
340   OUTPUT Testset;"CALL:MCC 234"
350   OUTPUT Testset;"CALL:MNC 56"
360   OUTPUT Testset;"CALL:PAG:REP:STAT:WCDMA ON

Set Generator Info Parameters

There are several downlink physical channels and an AWGN (Additive White Gaussian Noise) source which you can configure. You can set the power level of each physical channel (relative to cell power) and the absolute power level of the AWGN source. You can also specify that these channels use different power levels once an Active Cell connection has been established. For some of the physical channels you can also specify the channelization code. The downlink channel codes and levels required the operating mode be set to Cell Off for configuring.

 
370   ! Generator Info
380   !   -Downlink Channel Codes
390   OUTPUT Testset;"CALL:SCOD:PRIM 0"
400   OUTPUT Testset;"CALL:SRB:CCH:DED:BPS3400:CCOD CODE12"
410   OUTPUT Testset;"CALL:CCPC:SEC:CCOD CODE7"
420   OUTPUT Testset;"CALL:PICH:CCOD CODE16"
430   OUTPUT Testset;"CALL:AICH:CCOD CODE10"
440   OUTPUT Testset;"CALL:DPCH:RMC12:CCOD CODE9"
450   !   -Downlink Channel Levels
460   OUTPUT Testset;"CALL:CPIC -4.8"
470   OUTPUT Testset;"CALL:CCPC:PRIM -7.1"
480   OUTPUT Testset;"CALL:CCPC:SEC -6.9"
490   OUTPUT Testset;"CALL:PICH -9.9"
500   OUTPUT Testset;"CALL:AICH -9.9"
510   OUTPUT Testset;"CALL:DPCH -12"
520   !   -Connected DL Channel Levels
530   OUTPUT Testset;"CALL:CONN:CPIC -3.3"
540   OUTPUT Testset;"CALL:CONN:CCPC:PRIM -5.35"
550   OUTPUT Testset;"CALL:CONN:PICH -20" !Change PICH to give OCNS
560   OUTPUT Testset;"CALL:CONN:DPCH -10.3"
570   !   -AWGN Power
580   OUTPUT Testset;"CALL:AWGN:POW:STAT OFF"

Set Uplink Parameters

The example below illustrates how to configure the PRACH and how to indicate what primary scrambling code the UE is using. The operating mode must be Cell Off to set these parameters.

 
590   ! Uplink Parameters
600   OUTPUT Testset;"CALL:UPL:PRAC:POW:STEP 3"
610   OUTPUT Testset;"CALL:UPL:PRAC:SIGN 0"
620   OUTPUT Testset;"CALL:UPL:PRAC:SCOD 0"
630   OUTPUT Testset;"CALL:UPL:DPCH:SCOD 0"

Set up Call Parameters

You must set the frequency at which the downlink will transmit, by specifying either the UARFCN or the frequency.

You must indicate to the 8960 at what frequency the UE will transmit. (Unlike other technologies, in W-CDMA the uplink channel is not automatically determined based on the downlink channel. The offset between the uplink and downlink may vary based upon which band class you are operating in. So, you must specify the uplink frequency.) You can specify the expected uplink frequency by UARFCN or by frequency.

You can specify the downlink DPCH type (such as 12.2k RMC) and data type (such as PRBS15).

 
650   ! Call Parameters
660   OUTPUT Testset;"CALL:POW ";Rf_level
670   OUTPUT Testset;"CALL:DPCH:TYP RMC12"
680   OUTPUT Testset;"CALL:CHAN 10563"
690   OUTPUT Testset;"CALL:UPL:CHAN 9613"
700   OUTPUT Testset;"CALL:DTCH:DATA PRBS15"
710   OUTPUT Testset;"CALL:SRB:CCH:DED:DRAT BPS3400"

Set Uplink Channel Levels

As the example below illustrates, you can specify which closed loop power control bit sequence is sent on the downlink DPCCH.

It is important for you to specify what uplink power level the test set should expect by setting the MS Target Power. (In Active Cell mode, this command forces the UE to the specified output power. In FDD Test Mode, since the 8960 is not performing active closed loop power control of the uplink, this command does not change the UE's output power.) Setting the MS Target Power automatically sets the receiver's expected power accordingly.

 
720   ! Uplink Channel Levels
730   OUTPUT Testset;"CALL:CLPC:UPL:MODE ACT"
740   OUTPUT Testset;"CALL:MS:POW:TARG 0 DBM"

Set up Call Control

Finally, for performing the test set originated connection in Step 4: Make a Connection , you specify the UE's IMSI and change the operating mode back to Active Cell.

 
750   ! Call Control
760   OUTPUT Testset;"CALL:PAG:IMSI `1234567890'"
770   OUTPUT Testset;"CALL:OPER:MODE CALL"
