This document summarizes the resolved issues in different versions of BSC6900 GSM V900R017C10.
ed Audience This document is intended for: ● Field engineers ● System engineers ● Network shift engineers ● Network planning engineers
Provides the iCare or DTS number of a resolved issue. Provides a brief description of the issue. Specifies the severity of the issue. Specifies whether the issue has an impact on KPIs before an upgrade. Specifies whether the solution has an impact on the system. If yes, the solution has an impact on the system. If no, the solution has no impact on the system. Specifies whether the solution is under parameter control. If yes, the solution is controlled by a parameter. If no, the solution is not controlled by any parameter. Provides the default value of the parameter that controls the solution after an upgrade. If the solution is used by default, the issue is resolved without any parameter configurations. If the solution is not used by default, resolving the issue requires parameter configurations. Identifies whether the issue is involved in GU, GSM only, or UMTS only mode.

Description
Measurement results of TUNNEL.RATE.TX.AVG and TUNNEL.RATE.RX.AVG are invalid. BTS alarms are incorrectly displayed when you query board active alarms on the BSC device panel. The A/Ater interface board in the TC subrack incorrectly performs self-healing due to the signaling detection failure when the board signaling link is faulty.
A DPUb/DPUd/DPUg/DPUe board repeatedly resets after a hitless upgrade.
ALM-20704 OMU Data Synchronization Failure is reported unexpectedly.
Values of counters related to BTS IPPM measurement and BTS operator-level IPPM measurement are incorrect. The call drop rate increases when a GCGb board is not connected to antennas. Cells, NodeBs, NCPs/CCPs fail to be rehomed during automatic NodeB and cell allocation in GU mode.
A large number of service boards may be reset when an SCU is replaced.
The "10 G LINK" indicator on the SCUb is steady on when the 10GE port is in the link down state. The active and standby ports are incorrectly connected between a base station controller and PTNs in SBFD scenarios.
The OMU external heartbeat link experience a denial of service vulnerability.
Upgrade tool servers are abnormally terminated during an upgrade because they use the port for OMU service processes.
iCare: 4165515 No risk information is available when the host reset message is displayed. DTS: DTS20150 50403336 DTS: The SCUb may unexpectedly reset after the loopback detection of interDTS20150 subrack SCU cable connections is enabled. 62607503 DTS: DTS20150 42203602 iCare: 3746671 DTS: DTS20150 51104149 DTS: DTS20150 42201245 DTS: DTS20150 42908964 iCare: 4428861 DTS: DTS20150 52104936 DTS: DTS20150 51104830
All non-BCCH TRXs on the RF module carrying the BCCH TRX are faulty when the other RF module is faulty in cross-module RF FH mode. BTS PPP links or BTS MLPPP links fail to be configured when cascading relationships change. Domain users can still log in to the OMU using a proxy server even if the maximum number of online users has reached.
The MML command delivered by the U2000 fails to be executed.
The measured value of the VS.IPPOOL.ADJNODE.PING.MaxLOST counter exceeds 100% when transmission quality is poor. ALM-20909 Standby OMU Default Route Exception is incorrectly reported when the active and standby OMUs are running properly.
DTS: An SCTP link may fail to be established when both ends of the link are DTS20150 configured as clients. 52808460 DTS: If configuration data of boards in a subrack is not removed before the subrack DTS20150 is removed, services carried by other subracks are affected. 43005030 DTS: Values of VS.FEGE.RXPACKETS and VS.FEGE.RXBYTES for a GOUe board DTS20150 are incorrect. 42407098 DTS: No alarm is reported when the rate of the cable connected to the 10GE port on DTS20150 the SCU panel is inconsistent with the 10GE port fixed rate. 13104386 DTS: Ports on the SCUb boards in different subracks receive error packets when the DTS20150 boards are interconnected using 10-meter cables. 51503233 DTS: DTS20150 VAMOS call drops occur in the event of no downlink MR. 42804980
DTS: The policy for handling the reject cause value when MOCN Shared Cell is DTS20150 enabled does not take effect whenMOCN Rejection Cause Value Handle 60503448 Policyis set toSPECPROC-1. DTS: DTS20150 DTS: 41006541 DTS20150 52801382 Vulnerabilit y ID: HWPSIRT2015DTS: 05075 DTS20150 61200467
The information provided in the High-Risk Command List is incomplete.
A board configured with an SCTP link resets because of abnormal packet attack on the link. Adding a UMTS board with the logical type of RUCP or UCP fails after an upgrade from V900R015C00 to V900R017C10.
