LTE1130 Dynamic PUCCH allocation
Dynamic PUCCH allocation simplified process of PUCCH configuration
• eNodeB automatically calculates the required PUCCH resources based on selected values of PUCCH
parameters, system bandwidth, DRX, eICIC, MIMO and CA configuration
•
•
CQI periodicity 40 or 80 ms
SR periodicity 10, 20 or 40 ms

• PUCCH size is fixed, but set in dependence on calculated maximum number of RRC connected UEs
PUCCH size
 Traffic Vs RRC SR
 DATA Payload increased by 7%
 RRC SR Increased by 0.41%
 VoLTE Traffic Increased by 14%

Based on the TDD MRO Site NBR Cells ANR
was disabled to improve the HOSR.
HOSR analysis found that handover is
happening with the high inter site distance
and getting failed.
New NBR site got on aired but due to the
ANR disabled HO getting failed.
Post enabling the ANR we found that HOSR
Improved Significantly.
Case is based on the Particular issue.

Conclusion
—No degradation observed in any of the trial
—Most KPI have improved specially drop rate
—Some KPIs’ have no change
—On the 30th Evening there were some
fluctuation observed at Bhopal MPLS location
so VOLTE drops seems bit high in post.

MP&CG VOLTE Best Practices
Objective : To Improve the SRVCC success rate for Smoother mobility between 4G and legacy technology(2G) to provide the
excellent experience for Premium customers.

SRVCC KPI PRE_POST
Explanation: Role of A2/B2 time to trigger parameters in the
context of SRVCC to WCDMA:
Once SRVCC to WCDMA is enabled, below explained
parameters are valid in the context of WCDMA measurements
needed for SRVCC to WCDMA procedure
Parameter a2TimeToTriggerActWcdmaMeas defines how long
entering conditions for event A2 which triggers monitoring of
WCDMA layers must be valid, so that Measurement Report with
event A2 is sent by the UE to eNB.
Parameter b2TimeToTriggerUtraMeas defines how long entering
conditions for event B2 which triggers handover to WCDMA
layers must be valid, so that Measurement Report with event B2
is sent by the UE to eNB.

VOLTE Drop due to SW Issue
• VOLTE Drops increased due to the software issue site reset given for temporary issue.
• DL & UL PL increased due to the Software issue site reset done and KPI improved.
• Further Nokia has recommended the new software knife patch.

Activity carried out to improve PSR:
1) Parameter change paging occasions per radio frame for entire Network.( This activity is major contributor PSR improvement)
Parameter Name
pagingNb
Profile specific
Parameter name
Description
pagingNb
Paging nB defines the number of possible paging occasions per radio frame, i.e.
the density of paging occasions. This parameter is used to calculate the
number of paging occasions within one paging DRX duration, which in turn is
used to calculate the paging occasion.
2) RS Power Change 15.2 to 21.2 dBm in FDD Tech and RS Power Change 12.2 to 15.2 dBm in TDD.
3) 5 circles EPLMN removed

3G PN Pollution Analysis
Pilot Pollution
Definition : The number of strong cells exceeds the active set size, there is
“pilot pollution” in the area. Typically the active set size is 3, so if there are
more than 3 strong cells then there is pilot pollution.
Criteria : Below criteria have been consider for Pilot Pollution

Steps of execution.
TDD Harmonization
New EAFCN- 38750
Current EARFCN -38775
Please find the parameters below where we have to change the EARFCN at eNodeB,
NodeB and BTS level.
Steps of execution.
1.Create the XML for all the MO class
2.Before making the changes on LNCEL, Need to delete NBRs manually to avoid
duplicate NBRs with different frequency and New Nbrs will created automatically by
ANR
3.Changes in the LNCEL first and then rest MOs
4.Changes on all 2nd carrier frequency definitions created for IFHO
5.Change the EARFCN in ADJL(external definitions) with 2G and 3G
6.Drive test/Call testing from different locations after implementation.
7.Monitoring of OSS KPIs

First tier or required neighbors identification for load balancing(refer 031 report).
Switch of the ANR and post switching off ANR extract the LNREL dump.
Filter the neighbor relations, change the parameter amleallowed to 1 and removeallowed to 0, then implement the plan.
Post successful implementation of all given MOs and Parameters, start the ANR.
