Trial Summary

Timeline:

14thFebruaryChinese New Year (lower traffic week)

22ndFebruaryHSDPA activated on 1st& 2ndcarrier

Location:

RNC KPNG05

Ampang / Cheras / East KL area

HSPA Status

14thFebruary17 Sites with Dual-HS (R+H)

22ndFebruary260 sites with Dual-HS (H+H)

Conclusions

As expected


3/45


Balanced Load

Users can be spread across all carriers with load balancing

Conf i rmed

Improved PS CSSR KPI

No DRD PS calls setup on single carrier

PS CSSR actu al ly degraded due to IUB link qu ali ty

Maximizes HS Capacity

HSPA traffic uses all remaining resources after CS requirement

Confirmed

Maximizes HS Performance

HSPA USIC

Cell throughput & volume increase

Confirmed

Advantages of HS on all Carriers


4/45


RF Coverage / Quality

HSDPA degrades EcNo which leads to loss of good coverage quadrant (RSCP > -95, EcNo >

-12)

Conf irmed

Degraded RF Degraded KPIs

ALL KPIs could degrade due to more chance of RF failures and potential congestion

Conf irmed

More CS traffic pushed to 2G network

Conf irmed

Less CS traffic on 3G network

Conf irmed

Disadvantages of HS on all Carriers - #1


5/45


Network Concerns

Can current transmission / backhaul handle additional HS traffic if dual/tri-HS implemented?

Highl ighted current w eakness in IUB

Can 2G network support additional CS traffic?

2G performance and cus tomer experience impacted

Can current RNC support extra traffic? (analyzing as part of re-home exercise and all

approaching maximum capacity)

Capacity r eaching maxim um at end of 2010 with exist ing traf f ic, +45% addit ional traf fic

requires further expansion

RF coverage & quality improving but still requires more work before degrade with HS.

RF qual i ty and amou nt of fa i lures inc reased after act ivat ion

Disadvantages of HS on all Carriers - #2

CS Traffic:

Overall, other RNCs are maintaining the

similar CS Traffic.

However, the CS Traffic for RNC105 is

reduced after Dual HS activation, which

could be due to more IRAT to 2G (as shown

in IRAT per Call)

IRAT per Call:

RNC105 is having increased of IRAT per call

after Dual HS activation, whereas other

3rdCarrier & SKMM

2ndHS layer is required now

F1 under utilized could impact future license agreements with SKMM, need to show real

need for U900 persuasion.

KV 3rdcarrier upgrades on-going

RAN 11 Features (for R+H+H) DRD fallbackimproves PS CSSR KPI and allows marginal users to get PS service

Uplink Macro Diversity Intelligent Receiving: Improves resource utilization for CE &

IUB by reducing SHO overhead requirement

Dynamic Power Sharing of Multi-Carriers: Allows HS to use power resources from 1st

carrier when CS traffic is low. Can only share 2 carriers at the moment but suitable

for current network strategy

Proposals to maximize HS capacity and minimize CS impact


43/45


U900

Well known expected deployment to be used as complete primary network layer in future

Must be planned & deployed carefully & correctly, otherwise capacity will be impacted, not used for quick

capacity island site fixes.

Expect to be used as combined CS + HS layer and manage / balance U900 capable devices to this layer

will further improve capacity for 2100.

Dual / Tri-HS is coming, the question will be when?

Activate after Dec FA - 2010 optimization plan designed to improve 3G network and prepare for U900 /

HSPA+ deployment. Stabilize network this year, utilize current resources (3rdcarrier & RAN11 features) and

prepare for full HSPA+ deployment in 2011 and beyond

Activate after June PA

Attempt to over-achieve PA and request 6 month stability & best-effort optimizationperiod to balance performance & user experience

2011 and beyond network should be considered now i.e. transmission, RNC / NB capacity, borders etc.

Dynamic Power Sharing of Multi-Carriers

Application Scenario: Among multiple carriers, the carrier bearing HSPA service can

dynamically share the unused power resource of another carrier. This function

increases the utilization of the power amplifier as well as the HSPA service rate of

the cell.

Benefits

The capacity of the HSDPA cell increases by 5%-6%with only software upgrade
