• F2 carrier is barred, user will select back to F1 carrier after HSPA service end.• In idle mode users camp on F1 carrier and the HSPA calls are DRD to F2

carrier whereas voice calls stay on F1.

AdvantageEasy Configuration

F1 light loading,Good for CS service KPIDisadvantage Solution

After Enable CCH, PS call Drop Ratio will Increase for H2F reconfiguration overlap with cell re-selection.

Increase RB reconfiguration wait timer:SET USTATETIMER: RbRecfgRspTmr=60000;But UE may cannot response cell paging during cell re-selection.

All FACH users will keep in F1 cells,F1 cells FACH will easy congestion

Change to prefer camping or random camping strategy.

More DRD procedure need for F2H reconfiguration and increase reconfiguration delay.

Change to prefer camping strategy or random camping strategy.

AdvantageF1 cells light loading, Good for CS service KPI

PS KPI and user experience better than barred strategy after enable CCH.Disadvantage Solution

3% PS access and 1% CS access will establish at F2 cell directly.1% CS service KPI may affected by F2 HSPA service cell high loading.

This disadvantage is slightly.

Compare with random camping strategy, If most UE support HSPA, F1 cells will only bear AMR service and waste cell capacity.

Consider Change to random camping strategy increase network capacity and HSPA user experence.

Configuration more complex compare with barred and random strategy.

PS KPI and user experience better than barred strategy after enable CCH.Disadvantage Solution

CS KPI will Affected by HSPA traffic and worse compare with barred and prefer camping strategy.

More HSDPA code and cell license need for F1 cells.
