1/2

Power Cases: [no expansion for power at this phase]

1. Push user in idle to neighboring 2G/3G site for CS services.2. Ease HO to 2G/3G for CS services + CS/PS for island sites.3. Load reshuffle to 3G/GSM sites.4. F1/F2 dynamic load sharing.5. Eliminate Overshooting/overlapping by tilt optimization maintaining cell coverage target.6. Reduce ping pong by hysteresis and offsets.7. reduce AS to 3 for city and 1 for isolated sites.8. reduce R99 usage [use 1 RAB 32/64].9. Reduce in activity timers and speed up UE states up switching/down switching. [RNC level

HS/DCHFACH 5sec, FACH/idle 5 sec]

IuB cases:

Do the following for isolated sites.

1. Push user in idle to neighboring 2G/3G site for CS services.2. Ease HO to 2G/3G for CS services + CS/PS for island sites.3. Rxlevmin (-105/-100)/rxqualimin (-16/-14)4. Reduce HSUPA users to 1.5. reduce R99 PS usage [use 1 RAB 32/64].
