OSLO LTE Network KPI
These KPIs should be tested by Category 3 UE. And the Category 3 UE should be the commercial terminal.

done in the following test types:
1.Drive Test

KPIs:
These KPIs should be tested by drive test and statistic in M2000.
We can make and execute test tasks automatically when doing
Drive Test. The purpose is to create a heavy traffic environment
to statistic the probability.

KPIs:
These KPIs can be tested when doing the Single Site Service
Acceptance.
The items of Single Site Service Acceptance consists of the Ftp DL&UL
and ping latency . We need to select a good coverage location in each
cell to do the site acceptance.

KPIs:
These KPIs are about the performance of products, so we can test
them in the ATP Test of several typical sites.

KPIs:
These KPIs are about the performance of the whole network. So
we need to statistic in M2000.

Drive Test
At first, make sure the Drive Test System to work normally.
Then make two test tasks:
1.LTE/SAE Attach Success Rate and Call drop Rate: continuous short-time ftp download task
2.Intra-handover Success Rate and intra-handover latency:
long-time ftp download task
Create test tasks

Single Site Service Acceptance
These three KPIs can be tested in Single Site Service Acceptance :
1.FTP download average throughput for big file with one UE in the cell
2. FTP upload average throughput for big file with one UE in the cell
3. Ping RTT average time for 32 Bytes in the unloaded system with one UE in the cell
Good signal
RSRP>=-80dBm
&SINR>=30dB
Test Steps:
Ping with 32Bytes for 2 minutes

M2000 Traffic Statistic
The KPIs are about the performance of the whole network, so we
need to statistic them in M2000 in the background. Finally we can get
the statistical report from M2000.
Here is the definition of each KPI:
1.One round Paging Success Rate={100}*[L.Paging.UU.Succ]/[L.Paging.UU.Att]
2.One round Tracking Area Update success rate=100*S1_mode_TAU_success_times/S1_mode_TAU_times
3.SAE Bearer Setup Success Rate= 100* SAE_bearer_setup_success_times/ SAE_bearer_setup_request_times
Here is the statistical report:
