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.

Parameters for Voice Call:

1.1 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.

1.2 Setup time: the maximum time for call setup. If the call cannot be setup

within the defined period, the call setup fails.

1.3 Calling duration: the duration of one call, from call setup to call normal

release. (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 Interval ：The 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 support

the video calls.

3. PING

Note: PING packet size have an effect on PING delay time. Usually, the PING packet

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.

Parameters for PING:

4. 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.

Parameters for Ftp Upload / Ftp Download:

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 download path, 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 the number of

threads here.

4.5 Test Interval (sec): The time interval between multi downloads. After finishing

a download, wait for serveral time, then start another time’s download.

4.6 FTP Count: the total number of ftp download test.

Parameters for Ftp Upload / Ftp Download:

4.7 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 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.

5. HTTP

Parameters for HTTP:

5.1 URL：Refers to the destination HTTP address of the server.

5.2 Port：Refers to the HTTP serving port. By default, the value is 80.

5.3 Control Mode：Test by time and Test by RRC state.

5.4 Test Interval ：Refers to the interval between two HTTP tests. This

parameter takes effect when Control Mode is Test by Count.

5.5 HTTP Count：Refers to the total number of HTTP tests. This parameter

takes effect when Control Mode is Test by Count.

6. PDP

Note：If False is selected in Auto Dialup, the connections on the signaling plane are

set up. The signaling includes RRC signaling, PDP context activation request, and PDP

context activation receive message. The service plane, however, is not established. In

such a situation, the PING service is not being connected.

If True is selected, the connections on both signaling and service planes are

established. That is, the PC <-> UE <-> CN channel is set up for dialup connection and

providing services.

Parameters for PDP:

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

NAS Message window, we can see the Activate PDP context request &

Activate PDP context accept message, but we can’t perform service in this

mode. If the option is true, then there will setup a connection between PC<--

>UE<-->CN, the same as PS Dialup, we can perform service in this mode.

Reserved Duration: The period when the PDP is in active status, thus, it is time

from activate PDP context accept to deactivate PDP context request.

Test Interval: If a PDP test is success, wait for Test Interval to do next PDP test.

Then, it is time from deactivate PDP context accept to activate PDP context

request.

Exceptional Interval: If a PDP test is failed, wait for Exceptional Interval and

then do next PDP Test.

UL/DL Max Rate (Kbps)

UL/DL Guaranteed Rate (Kbps)

7. PS DaiUp / PS HangUp

The function of “PS Dialup” is

to setup a PS connection.

Parameters for PS Dialup:

7.1 APN: Access Point Name.

Ask the local PS domain engineer for the access point name. APN is named as

huawei.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, don’t set

the UL & DL Guaranteed V.

The UMTS Specifications specify that BE service has no requirement on

guarantee bit rate. Setting guarantee bit rate may result in PS connection setup

failure for many mobiles do not support the setting.

Supplements about APN, QoS Setting

a) 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 former setting will be maintained.

b) 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.

8. SMS

9.2 Test Count：the number of the cyclic plays.

10. Multi-RAB

Note: The Multi-RAB test supports PS and CS concurrent service tests. In

addition, this test provides the solution to the problem of failing to stop AMR

automatic test for the same mobile phone when the dialup connection of data

service is set up.

Parameter Window

Supplement for HSDPA Link Statistic:

Parameter Window

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 choose to 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 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

Served Rate = Scheduled Rate * HS-SCCH Success Rate

Mac Layer Rate = Served Rate * (1- SBLER)

Supplement for HSDPA Link Statistic:

3. IBLER, SBLER vs Res.BLER

IBLER is 1st MAC-hs error block /total 1st MAC-hs transmission blocks. IBLER

Target can be configured on NodeB. And it’s statistic value in Probe is 1st SBLER

in HSDPA Decoding Statistic Window.

SBLER is MAC-hs error block / total MAC-hs transmission blocks, IBLER target

configured on NodeB have an effect on SBLER, now the common value range of

SBLER is 10%~15%.

Res.BLER means remain BLER, which is within RLC layer. One transmission

block only after multi-times’ unsuccessful MAC-hs retransmission, will be

calculated as RLC layer error block, stat. to Res.BLER. Res.BLER is approximate

to 0 in normal instance.
