Set Test Plan for UE

1. Voice call


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.



25/111

25



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.

2. Video Phone


Suggestion: To conduct this test, the UE and the called terminal must supportthe video calls.



27/111

27



3. PING


Note: PING packet size have an effect on PING delay time. Usually, the PINGpacket size is described in the criterion of the test project, set the parameter

according to the criterion. Otherwise we can use the default setting: 32 Bytes if

there is no special requirement.



28/111

Parameters for PING:

4. Ftp Upload / Ftp Download


Note: PS connection can be set up by one FTP Download test item ifcorrect APN has been set in UE.



30/111

30


Parameters for Ftp Upload / FtpDownload:


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.



31/111

31


Parameters for Ftp Upload / FtpDownload:


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.

5. HTTP




33/111

33


Parameters for HTTP:

5.1 URLRefers to the destination HTTP address of the server.5.2 PortRefers to the HTTP serving port. By default, the value is 80.

5.3 Control ModeTest by time and Test by RRC state.

5.4 Test IntervalRefers to the interval between two HTTP tests. Thisparameter takes effect when Control Mode is Test by Count.

5.5 HTTP CountRefers to the total number of HTTP tests. This parametertakes effect when Control Mode is Test by Count.




34/111

6. PDP

est a Co gu at o e o e est

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.



35/111

35


Parameters for PDP:

g

Auto Dialup:If the option is false, then only setup signaling plane

connection. In NAS Messagewindow, we can see the Activate PDPcontext request & Activate PDP context acceptmessage, but wecant perform service in this mode. If the option is true, then therewill setup a connection between PCUECN, the same as PSDialup, we can perform service in this mode.

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.

7. PS DaiUp / PS HangUp

g

The function of PS Dialup is

to setup a PS connection.



37/111

37


Parameters for PS Dialup:

g

7.1 APN: Access Point Name.

Ask the local PS domain engineer for the access point name. APN is named ashuawei.com or huawei.

7.2 QoS

Traffic Class

UL Max V(kbit/s)uplink max rate

DL Max V(kbit/s)downlink max rate

UL Guaranteed V(kbit/s)uplink guarantee bit rate

DL Guaranteed V(kbit/s)downlink guarantee bit rate

Note: For BE service, such as Background Class and Interactive Class, dont

set the UL & DL Guaranteed V.The UMTS Specifications specify that BE service has no requirement onguarantee bit rate. Setting guarantee bit rate may result in PS connectionsetup failure for many mobiles do not support the setting.

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)
