Introduction to Cluster Optimization
Cluster Optimization Test Entrance Criteria Cluster Definition
(((

(((

Minimum of 20 to 30 eNB’s Contiguous coverage Can cross TA boundaries
Test entrance criteria
(((
(((
(((
(((
(((
(((
At least 80% of the eNB’s in the test cluster shall have passed SCFT and shall have compliance with EMF norms SCFT and EMF compliance report for each eNB for the test cluster has to be verified Any changes to the eNB physical configuration required for EMF compliance shall be updated in the cluster database
Cluster Optimization High-level Process Drive 1 • First cluster drive after 80 % of the sites pass SCFT & EMF
Optimization • Post-analysis changes to network
Drive 2 • Second Drive Test result will be compared with the first Drive Test for worst areas by measuring entire signal environment after change in System Parameters and adjustments of Antenna
Drive Route Selection UE should be served by all sectors of every eNB in the cluster Include highways, major and minor roads in the cluster Route should represent potential subscriber usage locations
Should not leave the designed coverage area for the cluster First and second drive routes should remain identical Conditions (e.g. UE position) should be identical between drives Do not cross 40 kmph
SCFT + Cluster Drive Case Suppose an eNB comes on-air after the rest of the cluster For that site, SCFT & Cluster optimization drive test should be done till first tier neighbors for the site
Drive Route for late on-air site
B
1. Drive route for Cluster when Site B is not on Air
B
2. Drive route for Sub Cluster after Site B is on Air
Test Procedure
Tests to be conducted FTP Downlink Long Call
FTP Uplink Long Call
VoLTE Long Call
4 UE’s : 1 Master, 3 Slaves
VoLTE Short Call
FTP Downlink Long Call Ensure that OCNS is enabled for all eNBs in the cluster with 76% downlink load Ensure that the UE is successfully attached to the LTE network Select the appropriate UE and download the FTP DL Scenario from FMS Start the Autocall test. FTP download uses a single file with the highest possible compression and file size of 8GB. (Attach to detach - 60 min & 10 Sec Idle time) Ensure that the log files are being captured Start traversing around the pre-defined drive route at 30-40 Kmph, continuing the FTP download and reinitiating in case of call drop At the end of the drive route stop the logging and ensure that the log files are uploaded
FTP Uplink Long Call Ensure that OCNS is enabled for all eNBs in the cluster with 76% downlink load Ensure that the UE is successfully attached to the LTE network Select the appropriate UE and download the FTP UL Scenario from FMS Start the Autocall test. FTP UL uses a single file of highest possible compression and file size of 1GB. ( Attach to detach - 60 min & 10 Sec Idle time) Ensure that the log files are being captured Start traversing around the pre-defined drive route at 30-40 Kmph, continuing the FTP upload and reinitiating in case of call drop
At the end of the drive route stop the logging and ensure that the log files are uploaded
VoLTE Long Call Ensure that OCNS is enabled for all eNBs in the cluster with 76% downlink load Ensure that the UE is successfully attached to the LTE network and successfully registered for VoLTE service Select the appropriate UE and download the VoLTE Long call Scenario from FMS Start the Autocall test. Ensure that the log files are being captured Start traversing around the pre-defined drive route at 30-40 Kmph, continuing the long call and reinitiating in case of call drop At the end of the drive route stop the logging and ensure that the log files are uploaded
VoLTE Short Call Ensure that OCNS is enabled for all eNBs in the cluster with 76% downlink load Ensure that the UE is successfully attached to the LTE network and successfully registered for VoLTE service Select the appropriate UE and download the VoLTE Short call Scenario from FMS Start the Autocall test. Ensure that the log files are being captured
Start traversing around the pre-defined drive route at 30-40 Kmph, continuing the short calls At the end of the drive route stop the logging and ensure that the log files are uploaded

FTP Test Call Upload & Download Ping from command prompt Loading effect 76% in the downlink Analysis of RSRP,SINR plot, PCI plot
Before starting drive test make a test call Before starting drive test try ping test Before starting drive test Optimization suggestions will be given after post processing of 1st drive test Optimization suggestions should be given and which will be implemented after 1st drive test in Cluster optimization
1. Analysis based on each sector coverage area and handover till adjacent cluster boundary 2.SCFT report should be considered for reference Analysis based on each sector coverage area using PCI plot of serving cell
Optimization suggestions should be given to reduce coverage overlapping and which will be implemented in after 1st drive test in Cluster optimization
Attach success rate, RACH success rate, Tracking area update success rate Analysis for weak DL & UL throughput areas. Analysis based on interference, overlapping, Handoff issues, SINR, hardware issues etc
KPI analysis w.r.t benchmark and optimization after 1st drive test
Handoff, call drop
Specific issues for Handoff, call drops should be analyzed and optimized accordingly Optimization suggestion should be given to improve worst areas
Analysis for the worst area for Throughput, SINR, Low coverage etc
Optimization suggestion should be given to improve weak throughput areas
