▫ Added support for Nemo Outdoor 6.1.0 corresponding to file format version 2.12.

▫ Added support for CDMA and EVDO for SwissQual Diversity

format.

Application layer improvements

▫ New queries to analyze RRC connections in LTE Call Trace files.

▫ New Spotlight KPIs for handovers from LTE to UMTS.

Platform improvements

▫ Added support PDF/CDF visualization in charts.

Known issues / obsolescence

▫ None.


2 New collection device or technology support

2.1 Ascom TEMS support

[Case 60894, 63968] A problem has been resolved that prevented Analyzer from correctly recognizing LG VL600 devices.

[Case 63858] A problem has been resolved that prevented Qualcomm

LTE protocol messages from being decoded.

CDMA analysis in Analyzer now uses the attribute PN_Scanner_Channel to create separate scanner frequency streams.

2.2 Couei / XCAL support

[Case 61153] A problem has been resolved that could cause log files containing a Nokia 6720 device to fail to load because of high memory usage.

2.3 Datapro support

[Case 63683] Improved timestamp decoding for new LTE devices.

2.4 Huawei CT support

[Case 63444] Added support for CHR message “Fault Single User Log”.

2.5 Motorola CT support

[Case 63057, 63957] Added event detection support for Motorola 2G call trace.

2.6 Nemo support

[Case 64345, 64373, 64549] Added support for Nemo Outdoor 6.1.0 corresponding to file format version 2.12.


2.7 NSN ICSU / Megamon support

[Case 64311] RRC “Cell Update” messages are now tracked, and as a consequence, Analyzer can now detect RRC Reestablishment procedures.

[Case 64206] A problem has been resolved that could set the attribute MsIMSI to multiple values for a single RRC connection.

2.8 Qualcomm chipset support

In LTE, new versions of the following messages are now supported:

0xB13C “LTE LL1 PUCCH Tx report”, version 4 0xB16E “LTE ML1 PUSCH power control”, version 4 0xB16F “LTE ML1 PUCCH power control”, version 4

[Case 63858] LTE measurements attributes (such as LTE_UE_Power_Tx_PUCCH, LTE_UE_FrameUsage_UL…) are now

set at 0xB16E “LTE ML1 PUSCH power control” and 0xB16F “LTE ML1 PUCCH power control” messages.

[Case 63073] In LTE, a new attribute LTE_UE_RLC_NumNACKs_UL is set to the number of RLC uplink PDUs that were NACK’ed by the eNode B.

[Case 62996] In LTE, a new attribute LTE_UE_PDCP_PDU_Discarded_DL is set to the number of missing

PDCP packets in the downlink.

[Case 62995] In LTE, two new attributes have been created for the SNR measured by the UE for each Rx-Tx pair:

LTE_UE_SNR_Rx0 LTE_UE_SNR_Rx1

[Case 61963, 62144] In LTE, a new preference has been introduced under “Tools > Preferences > General Settings > LTE > Create per-TTI attributes”. When this preference is enabled, Analyzer sets new array attributes for the most important LTE measurements to give the user access to every individual measurements made by the Qualcomm

device. This is useful for instance when creating detailed reports.

[Case 57738] A problem has been resolved with Qualcomm message

0xB17F “LTE ML1 serving cell measurements and evaluation” that affected how attribute LTE_UE_RSSI is calculated.

[Case 64284] A problem has been resolved that could cause Analyzer to fail to recognize a device if there were too many debug messages logged in the log file.

2.9 SwissQual Diversity support

[Case 63834] Added support for CDMA and EVDO.


2.10 Generic

LTE event detection can now detect handover failures from LTE to UMTS.

[Case 63107] LTE event detection now supports CS fallback from LTE to GSM.

[Case 63714] In UMTS, a new threshold has been introduced under “Tools > Display Thresholds > UMTS > Event_control > Uu_CallDropped_Normal_CC_Causes_range”. It controls which Call Control Disconnect message causes of type “normal event” are

considered as normal release causes by Analyzer event detection. The

“normal event” call control causes range from 0 to 31, and are represented as a bitmap where the LSB represents cause value “0” and the MSB represents cause value “31”. By default, all the “normal event” call control causes are considered as normal release causes, and therefore the default bitmap is 0xFFFFFFFF. One can remove “normal event” cause value n (with 0 ≤ n ≤ 31) from

the bitmap by computing the following: 0xFFFFFFFF – 2n. Note that the bitmap is represented as a decimal number in the threshold dialog box, so the default value is 0xFFFFFFFF = 4294967295.


3 Application layer improvements

3.1 Drilldown queries for LTE call trace files

Two new queries are available to analyze LTE call trace files and drilldown into individual connections.


3.2 New Spotlight KPIs for LTE to UMTS handover

Two new KPIs are available in Spotlight for LTE to UMTS handover success rate and failure rate:

Dashboard view Failure diagnostic


3.3 UMTS stateform improvement

[Case 62090] The “UMTS Active + Monitored Set” stateform now displays the serving UARFCN as well as the best inter-freq neighbour cell. The position of the best inter-frequency cell measurements in the table indicates its strength compared to the cells of the monitored set.

New “UMTS Active + Monitored Set” stateform


4 Platform improvements

4.1 Added support PDF/CDF visualization in charts.

[Case 60766] It is now possible to visualize the probability distribution function (PDF) and the cumulative distribution function (CDF) of an attribute in the chart view.


5 Known Issues / Obsolescence

None.
