What is the Point? –Initial Phase Inter-freq Handover is the most difficult for HSPA mobility optimization. HSPA Handover Handover Type
HO Success Ratio
The performance of Intrafreq freq HSPA HSPA servic service e cell cell change is based on the R99 intra-freq soft/softer handover.
H<->H Soft/Softer HO H<->D Intra-freq HO H<->H Inter-freq HO H<->D Inter-freq HO
HSPA shall cover hot spot area at initial phase on dedicated carrier, so there is too much inter-freq HSPA handover between hot-spot area and non hot-spot area.
H<->GPRS Inter-freq HO H<->H intra-freq Hard HO H<->D intra-freq Hard HO
Intra-freq hard handover is not suggested on commercial network.

HSPA and GPRS Handover is applied at the edge of UMTS coverage area.

HSPA Optimization in HO area Coverage quality of HO area decide the DL throughput for mobile HSPA user. The higher Load will not impact the pilot pollution but will be deteriorated in coverage quality of handover area. The poor CQI will be reported if the Ec/Io is very bad, DL throughput is close relative relative to CQI in HO area, so the the optimization for coverage in HO area is the key for mobile HSPA user.
This is the typical example for HSPA throughput optimization in dense urban. The average throughput of Application layer reach to 1.2Mbps.(Cat12 UE)
