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 handoveris not suggested oncommercial network.

HSPA shall cover hot spot area atinitial phase on dedicated carrier, sothere is too much inter-freq HSPAhandover between hot-spot areaand non hot-spot area.

The performance of Intra-freq HSPA service cellchange is based on theR99 intra-freq soft/softerhandover.

HSPA and GPRSHandover is applied atthe edge of UMTScoverage area.









































HSPA Optimization in HO area

Coverage quality of HO area decide the DL throughput for mobile HSPAuser.

The higher Load will not impact the pilotpollution but will be deteriorated in coveragequality of handover area.

This is the typical example for HSPAthroughput optimization in dense urban.The average throughput of Applicationlayer reach to 1.2Mbps.(Cat12 UE)

The poor CQI will be reported if the Ec/Io

is very bad, DL throughput is close relative to CQI in HO area, so the optimization for coverage in HO area is the key for mobile HSPA user.


























HSPA Throughput Optimization

The Power and Codes available for HS-PDSCH, the Iub bandwidth and RF environment of UE position will all impact throughput user got.

Question and Answer

What is the feature of HSPA?

AMC, Scheduler, lots of UE category, system resource allocation

What is most important before HSPA planning?

HSPA deployment strategy including coverage target, dedicated carrier,

service, etc.

What is the important input for HSPA coverage planning?

Cell edge throughput

What factor will impact HSPA throughput?

Environment condition, HSPA allowed load, CE/Iub resource. Huawei has advanced algorithm to improve the utilization efficiency.
