2G SSV Test Guide www.huawei.com Huawei Confidential Drive-test Data needed for SSV Test: Items Data needed 1 Engineering paramters 2 Map Description the 2G site Information ( BCCH, BSIC, LAC ,CI) Check whether the Latitude, Longitude & azimuth provided in Engineering parameters are Correct Huawei Confidential Page 2 1st test to check the 2G site information. 1. 2. 3. 4. 5. Before moving to the site you have to contact the OMC engineer or RF engineer to be sure the site is activated and doesn't have any alarms and all the service is activated on the site. If the answer from the OMC engineer or RF Engineer is OK so we can start our SSV test. After connecting you mobiles to the probe and confirm its connected on the Software the first test will be checking the site information. From the window of the UE State (View=> GSM=> GSM Radio Parameters) check CGI (MCC,MNC, LAC, CI), Rx Level Full for Idle & Rx Level Sub for Dedicated. You have to confirm the Data you get from the test is typical like the data from the engineering parameter then you have to fill the following table. Cell 1 No. Cell 2 Cell 3 Activity / Process Planned Found Planned Found Planned Found 1 BCCH as planned 2 BSIC as planned 3 Cross Connections checked 4 Rx Level > -85 dBm Near Site Yes Yes Yes 5 Rx Quality< 2 Near Site Yes Yes Yes 7 intra site handover normally Yes Yes Yes 8 MOC & MTC normal Yes Yes Yes 9 GPRS service is checked Yes Yes Yes Configuration Installation Coverage Service Huawei Confidential Page 3 How to discover the cross sector. 1. 2. 3. After you Check the BCCH & BSIC for each cell. You have to compare it with the engineering parameter data. And if you found BCCH from the field is not matching the data from the engineering parameters in this case we can say it’s cross sector. A. This case doesn't have a cross sector Huawei Confidential Page 4 Drive-Test Methodology We have to type of tests: 1. Stationary Test (For Function Check under each sector) 2. Mobility Test (To check coverage of the site) Huawei Confidential Page 5 Stationary Test & Mobility test The stationary test will be under each sector. We will be standing under the sector (not moving by car) to have a good RX level to make the function check. Check the Handover between all the sector clock wise & Anticlock wise and Handover with the Neighboring site Drive test route Stationary test point * Note:- The position you choose should be in LOS with antenna Huawei Confidential Test log Naming rules Folder name for every site XXXXX=SW+Site Name+mm+dd+YYYY With 3 Sub folders for every sector with the CI & one for SSV Huawei Confidential Thank You www.huawei.com www.huawei.com Huawei Confidential
