If Modern port is not configed, Probe still can keep track of part of the data, but can not start PS domain test automatically by Testplan, can not keep track of the throughput on the application layer, either. Probe is well-supported to terminal with Qualcomm’s chips. Probe can also support newfashioned UEs. But there maybe some problems on displaying parameters for the inner interface has been changed. When the terminal model does not exist on the list, please config a similar one. In addition, we suggest to check whether the associated parameter can normally displayed before the test.

Test Plan Configuration Before Test
Set Test Plan for UE 1. Voice call Suggestion: When testing voice call, do not perform PS dialup on the Modem of the 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 Call or Video Phone test. Thus, the CS and PS concurrent test can be performed on the same UE.
31
Test Plan Configuration Before Test
Parameters for Voice Call: Call type Continuous 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: call: 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 to call by call) Call interval: the time between two calls, from the previous call disconnection to the beginning of the next call. Exceptional Interval :The interval between the exceptional end of a call drop and the beginning of the next call. Count Mode: the limitations on the call number -> Finite / Infinite.

Set Test Plan for UE 2. Ftp Upload / Ftp Download Note: PS connection can be set up by one FTP Download test item if correct APN has been set in UE.
33
Test Plan Configuration Before Test
Parameters for Ftp Download / Ftp Upload : User, Password: FTP user name and password. For anonymous login, also need to input “anonymous” as username. Remote File: Destination file address, input the detailed download path, such as, ftp:// /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, wait for several time, then start another download test. FTP Count: the total number of ftp download test.
34
Test Plan Configuration Before Test
Parameters for Ftp Download / Ftp Upload: Disconnection Mode: the mode of Disconnection, there are three choices: Keep Disconnected: Do not perform PDP context deactivation ( remain RRC connection) after the target files are loaded completely, just wait for interval time then continue next ftp download test. Disconnect By Time: Perform PDP context deactivation periodically. The period for the PDP context deactivation is represented by the Valid FTP Duration parameter. 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. Disconnect After Transfer Complete: Each time when the file load is complete, PDP context deactivation would be performed. FTP QoS : Indicates the type of the traffic as: Background class Conversational class Interactive class Streaming class Subscribed class FTP Upload: Parameters are the same with FTP download’s. Probe will upload the local file to the destination path automatically. **Make sure you have the authority to upload file before test.

Test Plan Configuration Before Test
About APN, QoS Setting If leave APN, QoS parameters blank Probe won’t send the associated command to the UE if the parameters mentioned above is not set, that is the UE’s default setting will be maintained. Methods for setting APN, QoS 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 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 Probe’s setting doesn’t work if AT command also exists in the MODEM initial command. !!

Parameter Window WCDMA - Serving, Active Set & Neighboring Cells
Display PSC, RSCP, Ec/Io for active set, monitor set and detective set In the figure, rectangle legend implicates active set data, circle implicates monitor set data, and triangle implicates detected set data. The data of the same type is distinguished from each other with different colors. Move the mouse to a place to get the scrambling code of the current point. When the UE is in idle state, PSC in active set is about the cell where the UE resides.

UL/DL transmit power control
Parameter Window WCDMA - Power Control DL SIR, SIR Target Rx: UE received power; Tx: UE tx power UL/DL transmit power control Note: Whether SIR Target information can be acquired depends on the UE. UEs within Qualcomm’s chips don’t report SIR Target.
46
Parameter Window WCDMA - WCDMA BLER
Displays BLER of different transport channels. In HSDPA connection mode, A-DPCH's DL BLER is being displayed. Accompanying-DPCH
47
Parameter Window WCDMA - HSDPA Link Statistic 1. Delta vs Average
Delta is the average value in 200ms Average is the average value from the beginning of stat. to the current time. You can choose to clear the former stat. data. The values displayed by Assistant are all belong to Delta serial. 2. Parameters about rate Scheduled Rate = The total block size scheduled to the UE during stat. time / (Total time slot scheduled to the UE * 2ms) Served Rate = The total block size scheduled to the UE during stat. time /stat. time length HS-SCCH Success Rate = time slot number scheduled to the UE during stat. time / total time slot number during stat. time When multi UEs share a HS-SCCH channel, they will share channel resource. So, HS-SCCH Success Rate reflects the time ratio of a UE occupies HSDPA resource. The closer to 100% of total HS-SCCH Success Rate from UEs who share a HS-SCCH channel, the better schedule performance the system has. Served Rate = Scheduled Rate * HS-SCCH Success Rate Mac Layer Rate = Served Rate * (1- SBLER) 3. SBLER vs Res.BLER SBLER is MAC-hs error block / total MAC-hs transmission block, IBLER configed on NodeB have an effect on SBLER, typical value of IBLER is 10%, and common value range of SBLER is 10%~15%. Res.BLER means remain BLER, which is RLC layer BLER. One transmission block only after multi-times’ unsuccessful MAC-hs retransmission, will be caculated as RLC layer error block, stat. to Res.BLER. We can see from the test result that RLC BLER is usually 0.
