3 (7)

1. PURPOSE

The purpose of this document is to describe the effects and impacts that activation of this WCDMA BTS Software Maintenance Package (MP) will have on the customer’s network and how any new and changed functionalities will impact the operator network performance and the end user.

2. SW UPDATE DELIVERY EFFECT

WN6.0 MP4.1 BTS software package delivery contains:

Over 200 corrections

4 new features

All corrections are listed in Change Note document.

3. EFFECTS ON END-USER

The main effects are more detailed in next chapter. Those are improving end-user experience basically in all functional area

Improved set-up success rate

Better service availability (Cell availability, BTS and unit stability)

Better retainability

Better HSPA service

Improved operability for a operator

4. WN6.0 MP4.1 MAIN CORRECTIONS

4.1 Corrections for Flexi BTS

4.1.1 Set-up

RRC access failures due to radio

RRC set-up failures due to BTS

RAB setup failures for 3+3+3 sites with 2 LCGs

RAB CS failures cause BTS

o Buffering mechanism improvement in overload situation

Access failure rate due to BTS fails on FSMB+FSME sites, where the maximum CE usage exceeds approximately 600-650 CEs


4 (7)

4.1.2 HSPA

HSUPA setups fail due to transport unspecified reason (NBCC hanging) when F-DPCH activated

Low HSPA throughput as new user added as none user and getting serving grant as a 0

Low HSPA throughput, because BTS does not reply to capacity request sent by RNC

1 FSMB + 1 FSME configuration: HSPA is not allocated to FSMB (LCG1)

EDCH setup and success failures due to UE with FRGG unit

Inter & Intra BTS F-DPCH Mobility causes NBAP failures

HSPA drop calls in FSMB+FSMD/E configuration

Slot format 1 support added to Flexi rel1 system module

4.1.3 Capacity

Channel element (CE) amount downgraded without any alarms

Decreased capacity in BTS because the extension system module resources are available too late

Degraded state of extension FSME without alarm

4.1.4 FSP restart

Several corrections made for FSPC restarts perfomed due to:

fault 418

fault 1806

fault 1815

w1pl RX error

a NULL Pointer exception

4.1.5 RF Module corrections

RF module failure –alarm after too many heap reservations

Occasional RF module failure -alarm with fault 1920/1910

Remote radio head, FRGQ: uplink throughput degradation


5 (7)

4.1.6 Antenna line corrections

Several antenna line corrections implemented:

BTS Needs reset after antenna line device (ALD) failure alarm is cleared

"antenna line device failure" after FXDA block/unblock

After site reset some ALDs are missing in BTS Site Manger view

MHA AISG License Missing Alarm

4.1.7 Operability corrections

SW download and activation fixes

Baseband Bus failure

FRGF filter SW update failure

Flexi Rel 1 and Rel 2 BTS: SW DL fails because of wrong checksum calculation

Dual Carrier HSDPA Counters reporting occasionally abnormally high values

FTM VLAN measurements not available in NetAct

4.1.8 BTS start-up improvements

Baseband bus failure correction for FSMB+FSMD configuration

Failure in optical RP3 interface from extension system module during module start up

All of the above mentioned corrections and changes have been piloted in live customer networks and proven to work correctly.

4.2 Corrections for UltraSite

UltraSite SW content and files are the same as WN6.0 MP4.07 SW.

5. PILOTING

The WN6.0 MP4.1 SW was piloted by one main pilot in a customer network since the beginning of September 2011.

The pilot area consists of two RNCs and tens of BTSs, Flexi Rel 1 and Rel2 sites.

Improved KPI on all access failure rate

Improved Voice drop call rate (DCR)

Improved HSDPA and HSUPA PS DCR


6 (7)

Serving cell change showing overall improvement

FSPC 1806 failure issue resolved

Additionally there has been pilot in a smaller-scale cluster in another customer network.

The FXFA Multiradio RF Module has been piloted by two customers.

KPIs with the final SW are stable and on a good level.

6. RESTRICTIONS IN RELEASE

6.1 FXFA hot insert does not work properly

After plugging FXFA module to a running site, antenna line alarms and antenna line device alarms may occur. Site reset is required for recovering the antenna line functions.

6.2 FXFA LED indication is not correct

Wrong LED state, blinking red, may be displayed, when Radio Module Failure –fault alarm with fault id 1911 is reported from any of the radio module in BTS. Validity of module’s fault state need to be ensured from the alarms presented on BTS Site Manager.

6.3 Potential recovery problems after BTS restart with 3 x FXFA configuration

Alarm failure in optical RP3 interface reported after site reset

Telecom configuration failure (110) reported after site reset

7. NEW / CHANGED FUNCTIONALITY

7.1 New functionalities

RAN 1575: Flexi 3 sector RF Module 1900, FXFA. This feature enables support for Flexi FXFA Multiradio RF module.

CN4737: Y-type configuration 3+3+3@40 W support for FRIE module

CN4617: WCDMA configuration 3+3+3C+1+1+1A support for Flexi Release 2 BTS

CN4674: Antenna line voltage setting with AISG2.0 in Rel2.1 and Rel2.2 RF modules

7.2 Changed functionality

None

8. APPENDICES / REFERENCES

None
