3) Begin DT
i. The DT will follow before confirmed wimax DT boundary. Using Huawei
E398s USB terminal and Huawei Genex Probe DT software to perform the
DT. During the DT the engineers should parallel perform network entry,
minimum guarantee DownLoad/UpLoad test. By this after the DT can get
the test result of coverage probability/ successful setup rate / session
establish delay/ dropped session rate/ minimum rate guarantee of
downstream&upstream/ handoff/ wireless link burst error rate.
ii. All the streets should be covered. The speed should less than 30km/h. In
the DT engineers should always pay attention on the PCI/RSRP/SINR. If
any problem happened they should click the “pause” button to pause the
test and after solving continue the test. Any problems like KPI fail to
achieve must be informed to Huawei on time. After DT the log should be
transferred to Huawei.
iii. In the DT the team should always take care the PCI and performance, the
bad performance DT log or wrong test log will need repeating work. It is ok

SECRET
that feedback the problems to Huawei when you meet some problems.
4) Begin PT
i. Cell edge coverage probability
To the cell edge coverage probability, select 20 edge points (SINR is higher
than 0dB but lower than 5dB & RSRP is lower than -100dB) to perform ftp
download, each point last 1 min. Record the detail coordinates and test results.
The RSRP and SINR must be check from Probe, you can use test plan to
download and take a Snapshots like the “Average downstream throughput –
sector level” pictures, check the RSRP and SINR like this picture:
Acceptable range: successful rate> 80%
Target range: successful rate> 85%
ii. Average downstream throughput – terminal level
To the average downstream/upstream throughput (terminal level), select 3
points of one sector (RSRP=-105~-95 / -95~-80/ >-
80 、SINR=0~10/15~25/25~35) to perform the ftp download/ upload for 1 min.

SECRET
Record the average throughput of the 3 points. This test should be implemented
for 20% of sectors per cluster.
Please pay more attention to 3 points:
RSRP=-105~-95,SINR=0~10, keep the DL throughput between 5M to 15M
RSRP=-95~-80, SINR=15~25, keep the DL throughput between 25M to 35M
RSRP>-80, SINR=25~35, keep the DL throughput between 45M to 55M
The RSRP must be check from Probe, then you can test plan to finish this
work.This test plan PT will be provided by huawei. And you need to take a
Snapshots like the “Average downstream throughput – sector level” pictures.
DL:
Acceptable range: the result should higher than 4 Mbps ;
Target range: the result should higher than 4 Mbps;
UL:
Acceptable range: the result should higher than 1 Mbps ;
Target range: the result should higher than 1 Mbps ;
iii. Average downstream throughput – sector level
To the average downstream/upstream throughput (sector level), use 2 terminal
to perform the ftp download/ upload for 1 min at the same time. One point must
be meet the condition of Rank2 SINR1 >20 dB. The other point must be meet
the condition of MCS (in 16QAM) between 10 to 16(as below table). This test
should be implemented for 20% of sectors per cluster.

SECRET
Please pay more attention to the DL throughput of one point must over 35M.
The DL throughput of the other point must over 15M.
In addition, you need to add MCS to your PT logs, like this snapshot to open
MCS, and check DL MCS:

SECRET
The Rank2 SINR1 and MCS must be check from Probe, you can use FileZilla or
test plan, this test plan PT will be provided by huawei. And you need to take a
Snapshots like this:

SECRET

iv. Maximum round trip latency
To the Maximum round trip latency, select 1 edge point to perform the ping test.
This point must be meet the condition of -100<RSRP<-90.The ping packet size
is 32KB and the ping repeat time is 100. Record the average ping delay. This
test should be implemented for 20% of sectors per cluster.
Acceptable range: the average value is less than 60 ms;
Target range: the average value is less than 50 ms;
v. Maximum Jitteryf
Calculate the maximum jitter based on above ping result. 5 biggest jitter values
can be canceled. This test should be implemented for 20% of sectors per
cluster.
Acceptable range: less than 30 ms;
Target range: less than 20 ms;

3.Measure Method
KPI Test includes DT and PT (point test).
1) DT:
i. The DT will follow before confirmed wimax DT boundary. Using Huawei
E398s USB terminal and Huawei Genex Probe&Assistant DT software to
perform the DT. During the DT the engineers should parallel perform network
entry, minimum guarantee DownLoad/UpLoad test. By this after the DT can
get the test result of coverage probability/ successful setup rate / session
establish delay/ dropped session rate/ minimum rate guarantee of
downstream&upstream/ handoff/ HSR/ wireless link burst error rate.
ii. To the coverage probability, need to show out the statistic of points
percentage of RSRP>-110dBm&SINR>-3dB, show the RSRP & SINR & PCI
map picture.
iii. Successful setup rate= ERAB Setup Success Counter / ( ERAB Setup
Success Counter + ERAB Setup Failure Counter);
iv. Session establishment delay= T(Attach CMP)-T(Attach REQ);
v. Dropped session rate= ERAB Abnormal Rel Counter / ERAB Setup Suc
Counter.
vi. To the minimum rate guarantee of downstream&upstream, the engineers
will perform ftp download and upload by one fixed size file (DL 80MB and UL
20MB) with non-GBR account, the download&upload will be ceaselessly
repeated until finish the DT. Then calculate the average throughput of these
tests. The test result will be filtered as contract requirements and only the
valid service result will be calculated. This after filter result will be the KPI
result of this test item.
vii. Handover successful rate(HSR)= HO Success Counter / ( HO Success
Counter + HO Failure Counter);
viii. In any 1 min of the DT cannot happen more than 6 times HO, if this not
happen, the handoff test is passed.
ix. To the wireless link burst error rate, calculate the average RBLER in the
DT, the average RBLER of the DT should be less than 1% to achieve the
contract KPI.
x. All the above test result will be filtered as the RF test condition defined in
contract and the final result listed in the report should base on the test result
after this filter. The service drop or test fail happened at bad RF points
defined by contract will be excluded. Besides, Huawei should provide all the
original logs when submit the KPI reports.
2) PT:
xi. To the cell edge coverage probability, select 20 edge points (SINR is higher
than 0dB but lower than 5dB & RSRP is lower than -95dBm) to perform ftp

SECRET
download, each point last 1 min. Do a statistic for the successful service
points percentage.
xii. To the average downstream/upstream throughput (terminal level), select 3
points (RSRP=-105~-95 / -95~-80/ >-80) to perform the ftp download/ upload
for 1 min. Record the average throughput of the 3 points. This test should be
implemented for 20% of sectors per cluster
xiii. To the average downstream/upstream throughput (sector level), use 2 or 3
terminals (can be negotiated by Mobily & Huawei to detail test requiremtns)
to perform the ftp download/ upload for 1 min at the same time. In the 2
terminals condition the modulation should be around 64QAM and 16QAM.
This test should be implemented for 20% of sectors per cluster.
xiv. To the Maximum round trip latency, select 1 edge point (RSRP=-100~-90)
to perform the ping test. The ping packet size is 32KB and the ping repeat
times is 100. Record the average ping delay. This test should be
implemented for 20% of sectors per cluster.
xv. Calculate the maximum jitter based on above ping result. 5 biggest jitter
values should be canceled. This test should be implemented for 20% of
sectors per cluster.
xvi. As contract requirements, if the site has other commercial users, the
throughput KPI is not must achieved, DT team just normally record the test
result & the slot occupy rate from NOC M2000. For that the test is a long
term work and the ftp problem is always met, as to avoid any delay by the ftp
server, to all the ftp related test items Huawei can use either Mobily ftp server
(ftp.bayanat.com.sa) or Huawei server.
xvii. Huawei should provide all the original logs when submit the KPI reports.
xviii. KPI test report template
