Set Test Plan for UE

1. Voice call


Suggestion:When test ing voice cal l , do no t perform PS dialup on the Modem of the outg oing UE manual ly.

Otherwise, voice cal l maybe hangs up abnormal ly.

The UE that is performing PS services can serve as an incoming UE for Voice Cal l

or Video Phone test. Thus, the CS and PS concu rrent test can be performed o n the same UE.



31/68

g

Parameters fo r Voice Call:

Call type

Continuou s Call:The call continues if it does not fail, drop, or hang up. If the call fails, drops,or hangs up, Probe waits for a call interval to originate another call.

Call by Call : cal l:The call lasts and waits for the predetermined calling duration and call

interval, and repeats for the times defined in call count.

Setup time:the maximum time for call setup. If the call cannot be setup within the defined period,the call setup fails.

Calling duration:the duration of one call, from call setup to call normal release. (apply only tocall by call)

Call interval:the time between two calls, from the previous call disconnection to the beginning ofthe next call.

Exceptional Interval The interval between the exceptional end of a call drop and thebeginning of the next call.

Count Mode:the limitations on the call number -> Finite / Infinite.

2. Ftp Upload / Ftp Download


Note: PS conn ect ion can be set up by o ne FTP Down load test i tem i f correct APN has

been set in UE.



33/68

33


Parameters for Ftp Download / Ftp Upload:


User, Password:FTP user name and password. For anonymous login, also need to inputanonymous as username.

Remote File:Destination file address, input the detailed download path, such as,ftp://10.0.0.1/download/1.dat

Local File:Local path to save the download file, such as, C:\1.dat

MultiTask Count:When we use multi-threading download, set the number of threads here.

Test Interval (sec):The time interval between multi downloads. After finishing a download, waitfor several time, then start another download test.

FTP Count:the total number of ftp download test.



34/68

34


Parameters for Ftp Download / Ftp Upload:

est a Co gu at o e o e est

Disconnection Mode:the mode of Disconnection, there are three choices:

Keep Disconn ected:Do not perform PDP context deactivation ( remain RRC connection) afterthe target files are loaded completely, just wait for interval time then continue next ftp downloadtest.

Disconn ect By Time:Perform PDP context deactivation periodically. The period for the PDPcontext deactivation is represented by the Valid FTP Durationparameter. If the target files are

not loaded completely within the predefined time, the loading result shows timeout. Probe

considers this loading as failure and initiates another PDP context deactivation in the next

loading.Disconn ect After Transfer Com plete:Each time when the file load is complete, PDP

context deactivation would be performed.

FTP QoS :Indicates the type of the traffic as: Background classConversational class

Interactive class

Streaming class

Subscribed class

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.

About APN, QoS Sett ing

If leave APN, QoS parameters blank

Probe wont send the associated command to the UE if the parameters mentioned above is not set,

that is the UEs default setting will be maintained.

Methods for setting APN, QoS and their correlationship

1) Set by AT command in MODEM initial command2) Set by Probe in Test Plan

When both Probe and MODEM have APN and QoS information, because AT command in MODEM initial

command is send to UE more closely before PS connection setup, it will replace the information send to UE

by Probe. That is Probes setting doesnt work if AT command also exists in the MODEM initial command.
