n High QoS requirement of data service

Advantagen No impact on R99 coverage and capacity;

n No impact on R99 KPI;

n HSPA user can get high experience even in R99 busy time;

n High HSPA cell throughput.

Disadvantagen Spectrum utilization efficiency doesn’t reach

maximum;

n The whole cell capacity doesn’t reach maximum;

n HSPA users access HSPA cell by DRD, which bring about 200ms access delay;

n Inter-freq HSPA handover increases the difficulty of optimization.

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.

l Feb. 7th, 2007, Singapore’s 2nd largest mobile operator -- StarHub chooses Huawei as its sole UTRAN supplier to swap the existing unsatisfied performance vendor – Nokia

lJune 2007,more than 1200 sites are on air.

lAsia Pacific's first HSUPA commercial network with 1.92Mpbs uplink throughput, as well as 7.2Mbps HSPA for downlink

n Total 5000+ carriers for swapping & new sites Swapping all NOKIA existing sites and adding new sites

n Upgrade the existing network to HSPA & HSUPA

n 10-20% KPI improvement comparing to the pervious network

n Most of the Remote Radio Unit RRU were installed near to antenna so as to improve coverage and capacity thanks to cable loss reduction;

1st 7.2Mbps HSPA Network in Singapore

Benefit of 7.2Mbps HSPA to StarHubl StarHub is late in HSPA, existing Singapore mobile

network can only support 3.6Mbps.

l StarHub need HSPA capability higher up to

7.2Mbps to reseize the high-end data users.

l The leading HSPA solution will assist StarHub

overturn as the 1st 7.2Mbps network in Singapore.

Value from Huawei HSPA Solutionl First achieved 14.4Mbps on self-designed ASIC SOC

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.

What is highlight of Huawei HSPA CE consume?

High efficient CE for large HSPA throughput, on CE requirement for softer handover, no CE requirement for CCH; CE allocate dynamically for HSUPA; all cell in one NodeB can share CE resource.
