Strategy Recommendation for Mature Phase
The new traffic features for this phase is that total UMTS users will growth and proportion of HSPA will increase!
Advantagen Take full advantage of network resource
completely including spectrum and power;
n The HSPA cell capacity can reach maximum and provide higher capacity;
n HSPA KPI will be promoted for accessibility and mobility;
n Load reshuffle between two frequency will balance DL load;
n Difficulty of optimization will be reduced for service distribution is available.
Disadvantagen Investment for HSPA will be increased for
HSPA application on two frequency;
n HSPA User experience will be affected by R99 user pre-emptying resource;
n Load balance configuration will require more experience and optimization;
n Complicated and advanced RRM algorithm is required.

What is the Point? –Initial Phase
Inter-freq Handover is the most difficult for HSPA mobility optimization.
HSPA Handover Type
H<->H Soft/Softer HO
H<->D Intra-freq HO
H<->H Inter-freq HO
H<->D Inter-freq HO
H<->GPRS Inter-freq HO
H<->H intra-freq Hard HO
H<->D intra-freq Hard HO
HO Success Ratio
Intra-freq hard handover is not suggested on commercial network.
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.
The performance of Intra-freq HSPA service cell change is based on the R99 intra-freq soft/softer handover.
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 coveragequality of handover area.
This is the typical example for HSPA throughput optimization in dense urban. The average throughput of Application layer reach to 1.2Mbps.(Cat12 UE)
The poor CQI will be reported if the Ec/Io is very bad, DL throughput is closerelative to CQI in HO area, so the optimization for coverage in HO area is the key for mobile HSPA user.
