How do I monetize my network?
Use this as a segue or big
statement slide. Replace the
clouds with whatever icon you like.
QUICK TIP!
To make any icon transparent,
right click on it > edit shape >
solid fill > then adjust the
transparency!
Enhanced Service Enablement
From flat fee to value based pricing models
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)
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
Global application control
Per-subscriber application control
Quality of Experience Management
Optimizing capacity at the radio layer
Context-aware steering to video optimization / caching platforms
TCP optimization for increased “goodput”
Video Optimization
Transparent Caching
TCP Optimization for 3G
Opt-in / Opt-out Value Added Services
Personalized service packages
Security
Services
Ability to provide subscriber-based steering and filtering to
VAS platforms with service chaining capabilities
Monetization & Flexible Charging
OTT music streaming and messaging services
Volume Capping
Rest
Music Streaming
and/or Messaging
Unlimited
Ability to identify OTT application and
filter, rate control, count and mark this traffic
Monetizing the subscriber knowledge

Today's mobile broadband infrastructure faces challenges due to static and inflexible architecture, resulting in high costs and scalability issues. In response, re-architecting the Gi LAN to optimize and monetize services is crucial. By offloading value-added services and implementing intelligent traffic management, operators can enhance user experience, reduce costs, and drive new revenue streams in the evolving digital landscape.
