How Nokia address the challenges of the changes required

ObjectiveFiber Transport modelling tool to model D-RAN & vRANNetwork Architectures & identify optimal fiber routes & Hub locations that meet the use case requirements.
Main Capabilities
• Ensure fiber routes & hub locations meet latency requirements for the desired use case
• Identify Cell sites that don’t comply with the use case latency requirements
• Calculate DU/CU/Packet-Core site Aggregated traffic
Nokia Transport Modelling tools
Tool A Overview Tool B Overview
ObjectiveNetwork modelling vendor agnostic tool to study traffic impact on transport network & allowing to architect optimal network via economical analysis & comparison of different alternatives
Main Capabilities
• Any mix of technologies: RAN (GSM, UMTS, LTE,5G), Core Network (legacy, NGN, IMS), Transport (TDM, ATM, IP), Transmission (MW, Optics, DSL, GPON)
• E2E traffic modellinga) Congestion & saturation analysisb) Performance & reliability study
• E2E Network Latency Analysis
Can I achieve E2E target latency and resilience
Design Input
• Specific operator use case requirements
for latency target 12ms and resilience
• Existing 4G RAN layout and plan for 5G
• Transport map
• Each site must have two disjoint paths to
one of the 2 core (red square)
Design Output
• Green: less than 12 ms
• Yellow: between 12 and 20 ms
• Orange: more than 20 ms
• For sites not green, the working path is
fine, but the recovery path is close to the
target (yellow) or exceed the target
(orange)
Transport Network Verification

Design Input
• 5G use case requirements (URLLC)
• Existing 5G RAN layout
• Transport map (as if dark fibre)
Design Output with 1 CU location
• Cells in RED do not comply with the Latency
requirements of 50us
• 6 Cells with LOGICAL connection (Without actual
Fiber routes)

Have I sufficient distributed assets and POI to virtualise my RAN with e/CPRI ?
CU/DU/RU latency analysis
Get actual fibre routes & interconnect boxes, set targets
By optimising CU/DU locations & fibre routes ensures sufficient transmission for industry 4.0 or 5G small cells rollouts of the future
Check results for failing sites, propose new CU/DU locations from pool
Show map of sites with issues vs time plot. Show alternative locations
