Otherwise , voice ca l l maybe h angs u p abno rmal ly.The UE that i s per forming PS services can s erve as an incom ing UE for Voice Cal lor Video Phone tes t .

7. PS DaiUp / PS HangUp


The function of PS Dialup is

to setup a PS connection.


18/71

Param eters fo r PS Dialup :


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 setthe UL & DL Gu ranteed V.The UMTS Speci f ica t ions sp eci fy tha t BE service has n o requi rement o ngu arantee bi t rate. Set t ing gu arantee bi t rate may result in PS con nectio n setupfa ilure for many mob i les do no t suppo r t the se t t ing .

Supplem ents abou t APN, QoS Set t ing

a) If leave APN, QoS parameters blankProbe wont send the associated command to the UE if the parameters mentioned aboveis not set, that is the UEs 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 inMODEM initial command is send to UE more closely before PS connection setup, it willreplace the information send to UE by Probe. That is Probes setting doesnt work if ATcommand also exists in the MODEM initial command.

Parameters for F tp Upload / F tp Dow nload:


4.1 User, Password: FTP user name and password. For anonymous login, alsoneed to input anonymous as username.

4.2 Remote File: Destination file address, input the detailed download path, suchas, 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 ofthreads here.

4.5 Test Interval (sec): The time interval between multi downloads. After finishinga download, wait for serveral time, then start another times download.

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

T Pl C fi i B f T


22/71

22


Parameters for F tp Upload / F tp Dow nload:


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

Keep Disconn ected : Do not perform PDP context deactivation ( remain RRCconnection) after the target files are loaded completely, just wait for interval timethen continue next ftp download test.

Disconn ect By Time : Perform PDP context deactivation periodically. The period forthe PDP context deactivation is represented by the Valid FTP Duration parameter. Ifthe target files are not loaded completely within the predefined time, the loadingresult shows timeout. Probe considers this loading as failure and initiates anotherPDP context deactivation in the next loading.

Disconn ect Af ter Transfer Com ple te : Each time when the file load is complete, PDPcontext 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.

Supp lement for HSDPA Link Stat is t ic :

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 clearthe 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 length

HS-SCCH Success Rate = time slot number scheduled to the UE during stat. time / total time slotnumber during stat. time

When multi UEs share a HS-SCCH channel, they will share channel resource. So, HS-SCCH SuccessRate reflects the time ratio of a UE occupies HSDPA resource. The closer to 100% of total HS-SCCHSuccess Rate from UEs who share a HS-SCCH channel, the better schedule performance the system

has.

Served Rate = Scheduled Rate * HS-SCCH Success RateMac Layer Rate = Served Rate * (1- SBLER)

Supp lement for HSDPA Link Stat is t ic :

3. IBLER, SBLER vs Res.BLER

IBLER is 1st MAC-hs error block /total 1st MAC-hs transmission blocks. IBLERTarget can be configured on NodeB. And its statistic value in Probe is 1st SBLERin 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 ofSBLER is 10%~15%.

Res.BLER means 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 is approximateto 0 in normal instance.
