OBJECTIVE: 1. Improve accessibility & productivity2. Implement suitable state transition / channel switching strategy consider current network condition.3. Inter frequency load Balancing.

ISSUES DESCRIPTIONThe resource which is not good utilize make inefficiency resource in the system. Overshooting is one of blocking problem. Wee need to re audit the WPC of blocking and compare with TP analysis to reduce blocking due to overshoot. For site which is not overshoot but have high blocking, we need con-check the parameter. Otherwise the site need to be upgrade or need new site to solving the blocking problem.

ACTION PLAN LIST1. PERFENH_DTCH_FACH_CONG_D2I_SWITCH (plan on W10 2015 at 26 RNC)2. FACH_DTCH_CONGEST_P2D (plan on W10 2015 at 26 RNC)3. PERFENH_FACH_CONG_D2IDLE_SWITCH (plan on W10 2015 at 26 RNC)4.

Idle Layering paging (plan on W06 2015 at 25 RNC)8. FACH 200 user per cell (done on W46&47 2014 at 26 RNC)9. Load Based Dynamic Adjustment of PCPICH (Plan Rollout on w10 2015)10. HSDPA 96 Users per Cell (done on 1312 site at oct 2014)11. DPCH Maximum Power Restriction (plan on w04 for 26 RNC)12. EFD (done on w51 at 26 RNC)13. TPC PO Optimization (Done on 26RNC. 20 Jan 2015)

TARGET:1. 3G Blocking reduce >10%2. Count of cells that have 3G Blocking >0.5% reduce >10%3. All paging per LAC-RAC below threshold & paging deletion <1%
