Enhanced Service Enablement From flat fee to value based pricing models

Opt-in / Opt-Out Value Added Services

OTT Monetization & Flexible Charging

Intelligent and context-aware traffic steering to value added service platforms based on a subscriber opt-in/opt-out model

Monetizing OTT services by flexible charging mechanisms and OTT partnerships for service differentiation Monetizing the subscriber relationship using big data (targeted ads, mobile payment)

Quality of Experience Management

Bandwidth controls, TCP optimization and context-aware traffic steering to optimization platforms for enhancing the subsciber’s quality of experience


Quality of Experience Management Global and subscriber-based application control

Overall P2P = 10 Mbps Sub A “P2P” = 4 Mbps Sub B “P2P” = 4 Mbps

Sub C “P2P” = 4 Mbps

Sub A + B + C “P2P” = 10 Mbps

Even if subscriber is entitled for more by subscriber policy it gets limited based on the global policy

Gold Subscriber = 20 Mbps Rest = 10 Mbps

P2P = 4 Mbps

Even if subscriber is entitled for more by subscriber bandwidth policy his P2P traffic gets reduced to configured value (512kbps)

P2P = 512 kbps

Rest = 10 Mbps
