Vodafone NL – Market update
2 17 October 2016
Tough Competition:
4 MNO and more then 50 MVNO’s in
the market
P3 score are hitting the max of the
scale
Coverage footprint very high
Customer obsessed:
CXX is Key - all measures are aiming
for improvements which the customer
can really experience.
Networks - Access Engineering
High focus on 4G:
80% of the traffic is
on 4G
1Gbps site
3 Carrier
Aggregation
• Why use SON in a highly optimized network
• From 3G to 4G paving the way to 5G
• Efficient and Effective way to implement SON
• VF-NL implementation status
Vodafone NL : SON
Agenda

Vodafone NL – Why SON in a highly optimized network?
4 17 October 2016Networks - Access Engineering
Complexity is growing:
More parameters are driving the performance of the network
Customer demand is getting more diverse
Focus more on innovation instead of maintenance
Automate maintenance tasks and free up resources to innovate
Customer demand will require more clever solutions
Get the last bit of improvements from the network
Revenue per Gbyte is under pressure
Quality expectation of customs keeps on growing
Prepare for further personalization/profiling of the network
Increasing differences in how customers use their phone
Voice and Data will meet in the Data domain

Vodafone NL – Efficient and Effective way to implement SON
6 17 October 2016Networks - Access Engineering
Virtualized HW /IT environment
Easy test and activation of new features
Hardware efficiency
Easy scaling
Only use features relevant to market
Define goal then features
Prototype features before rollout
Partner with SON vendor
Create interworking between existing GEO tooling and SON
One size fits nobody
Adopt the network to customer demand

Vodafone NL – SON is not on it own
It needs to be included in the process: Optimization Cycles
A model has been design to identify improvement potential
Subsequently solutions get developed
Plan of approach, aligning the optimization cycles
to the Quarterly benchmarks

SON modules short description
Insert Confidentiality Level on title master 13
RAN Feature Short description
2G ANR Automatically optimize neighbours lists in GSM cell
3G UAGR Automatically optimize UMTS to GSM neighbour relations
3G ISHO Inter-System Handover optimization for UMTS networks (adapt thresholds)
3G SCO Detecting SC confusions and collision and resolves them
3G MEH Real-time self-optimizing network product that optimizes the radio access network (RAN) in a venue where a dynamic
mass event is held
4G PAE Suite for parameter organization
4G DPO Detecting PCI confusions and collision and resolves them
4G IRLB Inter-RAT Load Balancing from LTE to UMTS is a real-time SON product that balances the load between LTE and UMTS RAN
layers during highly loaded periods of the LTE network.
4G ICLB Inter Carrier Load Balancing for LTE (ICLB-L) provides a near-real time response to the unpredictable load challenges on
the LTE network using carrier re-selection to balance the most congested radio resource across the different carriers in the
same site.
4G CICO RF shaping suite that automatically detects the problematic areas and dynamically reduces their effect.
It optimizes coverage & interference situations
4G VCO (not GA) VoLTE: InterRAT voice continuity optimization in order to reduce VoLTE dropped call rate
4G VFBO (not GA) CS fallback optimization
