Set Test Plan for UE
1. Voice call
Test Plan Configuration Before Test
Suggestion:When testing voice call, do not perform PS dialup on the Modem ofthe outgoing UE manually. Otherwise, voice call maybe hangs up abnormally.The UE that is performing PS services can serve as an incoming UE for Voice Callor Video Phone test. Thus, the CS and PS concurrent test can be performed on thesame UE.

Parameters for Voice Call:
1.1 Call type
Continuous Call: The call continues if it does not fail, drop, or hang up. If the callfails, drops, or hangs up, Probe waits for a call interval to originate anothercall.
Call by Call: call: The call lasts and waits for the predetermined calling durationand call interval, and repeats for the times defined in call count.
1.2 Setup time: the maximum time for call setup. If the call cannot besetup within the defined period, the call setup fails.
1.3 Calling duration: the duration of one call, from call setup to call normalrelease. (apply only to call by call)
1.4 Call interval: the time between two calls, from the previous call
disconnection to the beginning of the next call.1.5 Exceptional IntervalThe interval between the exceptional end of a
call drop and the beginning of the next call.
1.6 Count Mode: the limitations on the call number -> Finite / Infinite.

4.1 User, Password: FTP user name and password. For anonymous login,
also need to input anonymous as username.
4.2 Remote File: Destination file address, input the detailed downloadpath, such as, ftp://10.0.0.1/download/1.dat
4.3 Local File: Local path to save the download file, such as, C:\1.dat
4.4 MultiTask Count: When we use multi-threading download, set thenumber of threads here.
4.5 Test Interval (sec): The time interval between multi downloads. Afterfinishing a download, wait for serveral time, then start another timesdownload.
4.6 FTP Count: the total number of ftp download test.

Test Plan Configuration Before Test
4.7 Disconnection Mode: the mode of Disconnection, there are three choices:
Keep Disconnected: Do not perform PDP context deactivation ( remain RRCconnection) after the target files are loaded completely, just wait for intervaltime then continue next ftp download test.
Disconnect By Time: Perform PDP context deactivation periodically. The periodfor the PDP context deactivation is represented by the Valid FTP Durationparameter. If the target files are not loaded completely within the predefinedtime, the loading result shows timeout. Probe considers this loading as failure
and initiates another PDP context deactivation in the next loading.
Disconnect After Transfer Complete: Each time when the file load is complete,PDP context deactivation would be performed.
FTP Upload:Parameters are the same with FTP downloads. Probe will upload the local
file to the destination path automatically.
Make sure you have the authority to upload file before test.

Note If False is selected in Auto Dialup, the connections on the signaling planeare set up. The signaling includes RRC signaling, PDP context activation request,
and PDP context activation receive message. The service plane, however, is notestablished. In such a situation, the PING service is not being connected.If True is selected, the connections on both signaling and service planes areestablished. That is, the PC UE CN channel is set up for dialup connectionand providing services.

Reserved Duration: The period when the PDP is in active status, thus, it istime from activate PDP context accept to deactivate PDP contextrequest.
Test Interval:If a PDP test is success, wait for Test Interval to do next PDPtest. Then, it is time from deactivate PDP context accept to activatePDP context request.
Exceptional Interval:If a PDP test is failed, wait for Exceptional Intervaland then do next PDP Test.

Supplements about APN, QoS Setting
a) If leave APN, QoS parameters blankProbe wont send the associated command to the UE if the parametersmentioned above is not set, that is the UEs former setting will be maintained.
b) Methods for setting APNQoS and their correlationship
1) Set by AT command in MODEM initial command
2) Set by Probe in Test Plan
When both Probe and MODEM have APN and QoS information, because ATcommand in MODEM initial command is send to UE more closely before PSconnection setup, it will replace the information send to UE by Probe. That isProbes setting doesnt work if AT command also exists in the MODEM initial
command.

1. Delta vs AverageDelta is the average value in 200ms.
Average is the average value from the beginning of stat. to the current time. You can chooseto clear the former stat. data. The values displayed by Assistant are all belong to Delta series.
2. Parameters about rateScheduled Rate = The total block size scheduled to the UE during stat. time / (Total time slotscheduled to the UE * 2ms)
Served Rate = The total block size scheduled to the UE during stat. time / stat. time lengthHS-SCCH Success Rate = time slot number scheduled to the UE during stat. time / total timeslot number during stat. time
When multi UEs share a HS-SCCH channel, they will share channel resource. So, HS-SCCHSuccess Rate reflects the time ratio of a UE occupies HSDPA resource. The closer to 100% oftotal HS-SCCH Success Rate from UEs who share a HS-SCCH channel, the better scheduleperformance the system has.
Served Rate = Scheduled Rate * HS-SCCH Success RateMac Layer Rate = Served Rate * (1- SBLER)

3. IBLER, SBLER vs Res.BLER
IBLERis 1st MAC-hs error block /total 1st MAC-hs transmission blocks.IBLER Target can be configured on NodeB. And its statistic value in Probeis 1st SBLER in HSDPA Decoding Statistic Window.
SBLERis MAC-hs error block / total MAC-hs transmission blocks, IBLERtarget configured on NodeB have an effect on SBLER, now the commonvalue range of SBLER is 10%~15%.
Res.BLERmeans remain BLER, which is within RLC layer. One transmissionblock only after multi-times unsuccessful MAC-hs retransmission, will becalculated as RLC layer error block, stat. to Res.BLER. Res.BLER isapproximate to 0 in normal instance.

The Probe supports customizing andloading project templates. All theproject templates are stored in the
sub-folder of the Template Projectfolder. When the Probe is beinginstalled, the following default foldersof different categories are generated.You can also set custom projecttemplates and save them in thedirectory. When multiple tests with asimilar function are being performed,
you can directly open thecorresponding project template butneed not carry out repeated projectsettings.
