2.1.6 Coverage Holl Optimization I. Task and Responsibility Data analyze engineer must find out coverage holl area and provide effective solution. II. Output Output figure of signal Rxlevel distributing into cluster Optimization report. Please refer to cluster optimization report template for detail requirement.
2.1.7 Any problem I. Task and Responsibility If there is no problems in phase 1 and coverage performance meet target .SRNO must submit Phase 1 cluster optimization report to HRNO. After check by HRNO,SRNO will start phase 2 optimization. If there are any problem in phase 1 and these problems need deal with by HBSS or RRNO. Please SRNO submit problem report to HRNO. II. Time point SRNO must submit cluster optimization report and problem report to HRNO within 1 day after finish data analyze.
2.1.8 Problem Check HRNO will check problem report , If no error in report it will be submit to RRNO ; if any error in report ,Problem report will be return to SRNO until no error in report.
2.1.9 Solve hardware problem Any hardware problem will be send to BSS engineer and must be solved by BSS engineer within 1 days.

2.1.10 Solve plan problem Any plan problem will be send to RRNO and must be solved within 3 days.
2.1.11 Transfer HRNO receive the tuning result from BSS or RRNO, HRNO will inform SRNO within 1 hour. SRNO will drive test again for whole cluster, if there are not any problem during test and coverage performance meet target . SRNO submit phase 1 optimization report. SRNO will start phase 2 optimization after check by HRNO. And this test result can be as test data for phase 2 . If there are any problem during test again or not meet DT performance target , The process will be roll out again until there are no problem and meet coverage performance target. All phase 1 work shall be finished within 4 days.

2.2.3 Drive Test Analyze I. Task and Responsibility In phase 2 ,SRNO must finish solving problems about C/I, Rxqual, BER, and abnormal event and ensure these performance meet target. II. Time Point SRNO must finish analyzing and output report within 3 day after receive the test data. III. Output SRNO must output problem report and cluster optimization report.
2.2.4 C/I, Rxruql , BER, Interference ,Event Optimization I. Task and Responsibility Actually these problem will refer to 5 ways Hardware Problem TRX Problem Antenna & Feeder Interference Intra-interference Inter-interference RF Problem Parameter Problem Equipment Problem Before starting cluster optimization, BSS engineer will clear alarm and solving 80％ hardware problem. So Huawei require SRNO must solve all interference and RF problem during phase 2 optimization. SRNO only ensure that inter-interference existing in network, not require find out interference resource. II. Output HRNO require SRNO must output distributing figure for C/I, Rxqual, BER, 2014-11-25
