Carry out SSV DT •

Before DT Test       

•

Driver test system connection Positions of the Test MS and Antenna Import: digital map, engineering table and test route GPS plot. Communicate with driver: driving route and speed. The log-files should not be too long, preferably less than 20 minute. The log-files should be named properly.

During DT test  Monitor the DT real results: Call setup, HO, Call drop, RxLev, RxQual, C/I  Analyze as much as possible. Ask driver to stop when abnormal  Pay attention to: bad quality, possible interfering sites, and topography and site locations  Correct small problems discovered immediately

•

After DT Test  DT log files and DT problem records. HUAWEI TECHNOLOGIES CO., LTD.
