Correction : HP80010/HP82979

W13B IP4 RBS Release Information | Commercial in confidence | 5/0363-4/FCP 130 8240 Uen, Rev B | 2013-09-17 | Page 13 (21)

Correction : HP80010/HP82979 › Drop mechanism › At DUW restart, RU changes the reference clock › Reestablishment of Time Alignment for active carriers takes too long › UE cannot detect DL messages due to bad timing

› Solution › Decrease the time for Time Alignment at reference clock change.(W12B IP1) › In case of high CPU load on RU, there might be some delay of reference

switch that will still cause call drop on L. › RU SW optimization to reduce RU CPU load.(W13A)

W13B IP4 RBS Release Information | Commercial in confidence | 5/0363-4/FCP 130 8240 Uen, Rev B | 2013-09-17 | Page 15 (21)

Correction : HR58908 1)SCTP association becomes congested due to transmission disturbance 2)RBS receives SCTP association restart indicator after the transmission

recovery 3)However, RBS does not interpret the indicator correctly and keep

considering the SCTP is congested (SW fault) 4)RBS cannot send AUDIT RESPONSE and AUDIT REQUEST from RNC is

timed out

NBAP

IP/SCTP

NBAP

IP/SCTP

RNC RBS NBAP AUDIT REQUEST

RBS cannot send “AUDIT RESPONSE” since SCTP is regarded as congested even after the recovery

With the correction, RBS can detect SCTP recovoery properly and missing “AUDIT RESPONSE” will never occur

Regarded as congested

Correction : HQ95704 –Fault

› The problem is seen with RBS3303 CBU using -48 V DC power. › Alarm is raised due to un-expected program status:

Program=CXC1322165/12_R79X04 (ENABLED). › This program MO is not a necessary one for certain type of RBS. › RBS did not call the action updateconfiguration() to trigger the plug and play

functionality to remove the unnecessary programs after the re-arrange the repertories for swallocation Main_Cbu.

–Remedy › Manually delete the MO: Program=CXC1322165/12_R79X04.

–Solution › In the Cabinet configure wizard, call the action updateConfiguration() after

configure RBS type. › Create a new AUE to delete the program= CXC1322165/12 during upgrade.

Correction : HQ18285

W13B IP4 RBS Release Information | Commercial in confidence | 5/0363-4/FCP 130 8240 Uen, Rev B | 2013-09-17 | Page 20 (21)

Correction : HQ18285 –Fault

› ET-MFX restart happens when there is no restart within 199 days after previous restart.

› It is caused by using uninitialized pointer in timer function.

–Solution › Incorrect memory addressing that was causing uninitialized pointer

access has been corrected. › Solution for RNC ET-MFX has already been applied in live network.
