Network optimisation software can provide measurable benefits for mobile networks. The software uses algorithms and automation to optimize spectrum refarming, traffic shifting between network layers, and network grid layouts. This reduces costs while improving quality of experience and increasing revenue. Case studies demonstrate the software successfully optimizing large networks overnight and improving key performance indicators.

• Network grid optimisation
Be smart, get more
Get max from your team
• Process (semi)automation

4. Challenge
• RAN is a living and very dynamic environment
• Defining optimal parameters requires complex computations
Network Optimisation
Solution
• Software solution efficiently supporting the process (repeatability and reproducibility)
• Algorithms at the cutting edge of computer sciences
Benefits
• Better services using the same assets – higher QoE / QoS
• More traffic using the same assets – higher revenue

5. Spectrum Refarming & Traffic Shifting
Challenge
• Exponential growth of PS traffic
• Differences in spectral efficiency of access technologies
• Management of multilayer networks
Solution
• Shift of PS traffic to more efficient network layers
• Shift of spectral resources from 2G to 3G or 4G, keeping the QoS for CS
Benefits
• Lower CAPEX (spectrum)
• Lower OPEX (deactivation of TRX)

6. Challenge
• Site maintenance costs is an important part of OPEX
• Network grids developed incrementally, so its structure could be suboptimal
Network Grid Optimisation
Solution
• Reshaping of the grid taking into account e.g.:
• maintenance costs,
• profitability,
• future network structure (5G)
Benefits
• Lower OPEX

7. Problem
• SON solutions don’t meet expectations (scope, scale, complexity, results)
• A lot of daily activities is still based on tedious, time-consuming manual work
Process (Semi)automation
Solution
• Process optimisation based on Kaizen philosophy
• IT system efficiently supporting engineers in most frequent, complex or time-consuming
tasks
Benefits
• Higher efficiency of the engineering team – more closed tickets
• Process repeatability and reproducibility
• Fewer human (expensive) mistakes
