Title: Memory leak in BTS, causing spontaneous BTS restart Version of the SW-build: WN6.0 PP0.1 (WN6.0 19.5-158_C) Valid for Product(s): Flexi WCDMA BTS References: Reason for the Change Note: Problem: Memory leak in BTS, causing spontaneous BTS restart. Root cause: ALMAG (antenna line management) was not ready to handle bad case in device scanning. It occurs when devices on one antenna line with address assignment still replies on scanning messages. It leads to very high and expanded binary tree which consumed more and more memory. Correction: The correction is that there could be max 20 devices on one antenna line, binary tree height is 152, so no it might be 20 * 152 = 3040 max scanning messages sent and scanning is stopped.

Root cause: Problem1: When congestion is detected on Iub, congestion control does not allocate credits for inactive users. Because of averaging/rounding in SW, sometimes low data rate users on a narrow Iub case may end up being determined as inactive even if there were PDU arrivals recently. Problem2: Secondly, the calculated credits were not updated to users unless they were selected for credit reduction.

Corrections: Correction1: After the correction the user is considered active if it has had data waiting to be transmitted in RNC user buffer during last 80ms. Correction2: After the correction: the calculated credits are updated without credit reduction multiplier in case they were not selected for credit reduction.

Version of the SW-build: WN6.0 MP1 (WN6.0 19.5-179) Valid for Product(s): Flexi WCDMA Base Station References: Reason for the Change Note: Problem: BTS allocates HSDPA credits too aggressively on narrow Iub bandwidth causing rapid increase in A2SP data queue. Root cause: SW bug in TUP SW negated the effect of a credit calculation ramp-up term which should limit the amount of credits (MAC-d PDUs) per user to increase according to amount of MAC-d PDUs received from the Iub interface. Correction: After the correction the maximum credits per user can be up to 2 * received_PDUs + 10. This is rather aggressive ramp-up which adapts to different Iub capacities. In order to keep a good performance with interactive traffic and in beginning of the connection, in case of short gaps in the data transmission, this term does not immediately revert to initial value (10) but is slowly decreased during gaps.

Title: Can not open snapshot with BTS Site Manager version WN60-6.1.92 Version of the SW-build: WN6.0 MP1 (WN6.0 19.5-179) Valid for Product(s): Flexi WCDMA Base Station UltraSite WCDMA Base Station References: Reason for the Change Note: Problem: Can not open snapshot with BTS Site Manager version WN60-6.1.92 Root cause: Snapshot file handling problem in BTS Site Manager Correction: Snapshot file handling problem corrected. Corrected Fault Reports: 40499ESPE03 Can not open snapshot if SEM version BTSSiteEM-WN60-6.1.92 is installed to PC Modified components: Component Version cl.jar 4.0.40 Change effects:



Customer Impact: Operation & Maintenance: Can not open snapshot with BTS Site Manager version WN60-6.1. Testing Instructions for the change Pre-requirements: Test execution: This correction cannot be tested using the operator interface commands. The correction is tested internally in Nokia Siemens Networks test lab and proved to be fully functional Expected results: - Unexpected results:

Title: Improvement related to RAN1638: Flexible RLC (DL): Version of the SW-build: WN6.0 MP1 (WN6.0 19.5-179) Valid for Product(s): Flexi WCDMA Base Station References: Reason for the Change Note:

Improvement related to RAN1638: Flexible RLC (DL): Root cause / Change: RAN1638: Flexible RLC (DL): The flow control with HS-DSCH Capacity Allocation Type 2 is upgraded to be capable of signaling any data rate accurately to RNC. Previously the accuracy was a multiplication of 1 MAC-d PDU, which is expected to be non-optimal for large PDU sizes on cell edge or in narrow Iub conditions. Corrected Fault Reports: Modified components: Component Version TUP SW WN6.0 12.4-172_A Change effects:



Customer Impact: Capacity & performance: Less drop calls in the cell edge or in narrow Iub conditions when Flexible RLC feature is enabled. Testing Instructions for the change Pre-requirements: Test execution: This correction cannot be tested using the operator interface commands. The correction is tested internally in Nokia Siemens Networks test lab and proved to be fully functional Expected results: - Unexpected results:

Title: Data base conversion problem eliminating the decimals from the feeder loss. Version of the SW-build: WN6.0 MP1 (WN6.0 19.5-179) Valid for Product(s): Flexi WCDMA Base Station UltraSite WCDMA Base Station References: Reason for the Change Note: Problem: DB conversion from WN5.0 to WN6.0 is eliminating decimal figures of feeder loss parameter, i.e., if the right feeder loss is -2.8 in WN5.0 DB and you open it with RU20 WBTS Site Manager, which converts the value, the decimal figure is missing and the feeder loss parameter value is -2.0 Root cause: DB conversion problem in BTS Site Manager. Correction: DB conversion problem corrected Corrected Fault Reports: NA04726434: DB conversion from WN5.0 to WN6.0 it's eliminating decimal figures of feeder loss parameter. Modified components: Component Version common.jar WN6.0 19. 5-173_A Change effects:



New functionality

Customer Impact: Capacity & Performance: Possible KPI degradation due to incorrect feeder loss value. Testing Instructions for the change Pre-requirements: Test execution: This correction cannot be tested using the operator interface commands. The correction is tested internally in Nokia Siemens Networks test lab and proved to be fully functional Expected results: - Unexpected results:

Title: Reduced HSDPA throughput when Congestion Control feature is enabled with RU20.

Version of the SW-build: WN6.0 MP1 (WN6.0 19.5-179) Valid for Product(s): Flexi WCDMA Base Station UltraSite WCDMA Base Station References: Reason for the Change Note: Problem: Reduced HSDPA throughput when Congestion Control feature is enabled with RU20. Root cause: Problem in the BTS delay calculation functionality resulting the positive bias in the delay calculations. Overtime as the delay accumulated it eventually crossed the delay threshold and Congestio
