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
