14/76
Single Site Verification
Purpose:
The single site verification test is a part of the WCDMA networkoptimization to ensure that the basic functions of the cell are normal,such as call access, call quality, handover and so on.
Single site verification involves the following aspects:
Parameter setting check in idle mode
Services call (AMR/VP/PS) function check in connected mode
HSDPA function check
CPICH RSCP & Ec/Io
Installing problems check

15/76
Single Site Verification
Single site verification includes :
preparations before test
single site test
solving problems
The single site verification is completed by:
On-site engineers
RNO engineers

16/76
Single Site Verification - Task of the on-site engineers
Preparations
Site Status Check
For each cell to be measured, check Status by LMT or M2000 Status
Configuration Data Collection and Check
check whether the data configured is consistent with the planned data
Testing Point Selection
Test UE Setup
Set the handset to testing mode before test
Other Preparations
Application key

17/76
Verification in Idle Mode
Frequency Check
Check whether the frequency number of the cell to be measured isconsistent with the planned data
Scramble Check
Check whether the scramble configuration is consistent with the
planned configuration
LAC/RAC Check
Check whether the LAC/RAC of the cell to be measured is consistentwith the planed one.
CPICH_RSCP/CPICH_Ec/Io (Near Site) Test
Check whether the CPICH RSCP and CPICH Ec/Io received by UE aregreater than the threshold

18/76
Verification in connect Mode
Originating and Terminating Connection Test of Voice Service
Check whether the originating and terminating function of voice servicefunction normally by call quality test
Originating and Terminating Connection Test of VP Service
Check whether the originating and terminating function of VP service
function normally by call quality test
Connection Test of PS Services
Check whether the originating function of PS services are normal byhandset online service
Solving Problems
If on-site engineers find product function problems or parameter configurationproblems, the engineers must location them and retest until the problems aresolved and process terminates.

19/76
Preparations
Cell Status Confirmation
Before checking site, you need to inquiry product support engineerswhether the cell is in normal status
Testing Route Selection
Before test, you must select a proper testing route according to site
distribution and local environment
Precautions
Single Site Verification Task of the RNO engineers

20/76

21/76
HSDPA Access Function Test
To test HSDPA access function
Antenna Diversity Check
Check whether the antenna for receiving diversity signals is reverselyconnected
Fixed Maximum Transmit Power of UE, measure the RTWP of the cells
Checking Antennas by Exchanging Feeders
Single Site Verification Task of the RNO engineers

22/76
Antenna Diversity Check
The method for UE to transmit signals at the fixed maximum poweris a recommended method of test and operation
Solving Problems
