Introduction

2nd Carrier on site U0265 was activated on 11/04/2012 andleft on air for Performance Monitoring Purpose.

Besides maintaining the DCR and CSSR at an acceptablelevels, the main goal was to achieve the goal of keepingmost of the Speech traffic on the 1st carrier while pushingHS traffic on the 2nd carrier.

We have tested 3 cases:

TC1: (LSM (F1)=20, LSM (F2)=0, PwrAdm (F1)=75, PwrAdm (F2) =75)

TC2: (IFLoadSharing disabled. To check if our idle mode strategy works (All UEsshould camp on F1) and initiates calls from F1)

TC3: (LSM (F1)=0, LSM (F2)=10, PwrAdm (F1)=50, PwrAdm(F2)=90) In the following slides we will present the result of our tests

from 11/04/2012 to 12/04/2012 on a hourly basis.

U0265 G1/G2 - Load Sharing - RRC

LSM (F1)=20

LSM (F2)=0

PwrAdm (F1)=75

PwrAdm(F2)=75

Load Sharing

Disabled

LSM (F1)=0

LSM (F2)=10

PwrAdm (F1)=50

PwrAdm(F2)=90

No Load Sharing Activity from F2 to F1

On both Test cases.

Load Sharing Activity from F1 to F2

TC3 compared and TC1.

IFLS was disabled

and all the RRC Connection

Requests are initiated from F1 instead of F2

meaning our camping strategy works.

U0265 H1/H2 - Load Sharing - RRC

Load Sharing Activity from F1 to F2

On TC1 and TC3.

No Load Sharing Activity from F2 to F1

On Both Test cases.

IFLS was disabled

and all the RRC Connection

Requests are initiated from F1 instead of F2meaning our camping strategy works.


5/40


U0265 J1/J2 - Load Sharing - RRC

IFLS was disabled

and all the RRC Connections areRequested from F1 instead of F2

meaning our camping strategy works.


6/40


U0265 G1/G2 - CSSR

No significant change on

CSSR_HS/EUL on both carriers

And on both test cases.

CSSR_Sp is steady and

did not degrade

On both test cases and

both carriers

U0265 H1/H2 - Load Sharing - Speech

Most of the speech traffic stayed on F1

On TC1 .

Most of the speech traffic was pushed to F2

On TC3: .

U0265 J1/J2 - Load Sharing - Speech

Most of the speech traffic was pushed to F2

On TC3: .

U0265 G1/G2 - Load Sharing PS R99 Volume

R99 traffic was pushed to F2 in both Test Cases.

Which makes sense since this RAB is used on the UL

By HS Users. The increase is more pronounced on TC3

U0265 G1/G2 - Load Sharing # HS Users

HS traffic was pushed to F2 in both Test Cases.

The amount pushed is more pronounced on TC3

U0265 H1/H2 - Load Sharing # HS Users

HS traffic was pushed to F2 in both Test Cases.

The amount pushed is more pronounced on TC3


17/40


U0265 J1/J2 - Load Sharing # HS Users

HS traffic stayed in F1 in both Test Cases due

To the low traffic level in U0265J1. Based on the

pwrAdm settings on J1 , IFLS triggering did not

Happen.

U0265 G1/G2 DCR_Speech

DCR_Sp has improved on F2

There was no degradation on

DCR_Speech on F1

U0265 H1/H2 DCR_Speech


DCR_Sp has improved on F2

And is steady on F1

U0265 J1/J2 DCR_Speech

DCR_Sp is steady on both

Carriers and test cases.

U0265G1 - Load Sharing

As seen on the previous

slides, the share of IFLS

For PS services is higher

than that of CS services

IFLS was disabled

As seen on the previous

slides, the share of IFLS

For PS services is higher

than that of CS services


25/40


U0265H1- Load Sharing

As in the case of U0265G1, the share of PS services on IFLS is higher of that of CSServices


26/40


U0265J1 - Load Sharing

There was no much IFLS activity on U0265J1 due to the level of traffic and thepwrAdm setting not enough to trigger IFLS

Conclusion and Data

2nd Carrier on site U0265 was unlocked on 11/04/2012 and left on air for

Performance Monitoring Purpose. We tested 3 cases:

TC1: (LSM (F1)=20, LSM (F2)=0, PwrAdm (F1)=75,PwrAdm(F2)=75)

TC2: (IFLoadSharing disabled. To check if our idle mode startegyworks (All UEs should camp on F1))

TC3: (LSM (F1)=0, LSM (F2)=10, PwrAdm (F1)=50,PwrAdm(F2)=90)

There was no significant change on CSSR_HS/EUL on both carriers and onboth test cases (TC1 and TC3).

IFLS share for PS services was higher than that of CS services as we hadmuch of HS traffic pushed to F2 on TC1 and TC3. However, on TC3, Speech

traffic was pushed to F2 as well. We are working on this issue. IFHO success rate was good for all sectors.

CounterpmTransmittedCarrierPowerNonHsis still not yet activated.Once activated, it will allow us to know the correct values of the Powerconsumed by R99 services per sector and thus to set accurately thepwrAdm and LoadSharingMargin values per sector.
