As voice revenue plummets and investments in fiber and LTE access technologies continue, Communication Service Providers need to accelerate IP monetization with new data services.

Launching differentiated packages means being able to understand subscribers’ behaviors and to control and charge data traffic depending on application based criteria.  However, these capabilities, specified in the PCEF (Policy and Charging Enforcement Function) by 3GPP standard, are not included or not efficient enough in packet gateways (GGSN, PDN-GW or BRAS). Vedicis DPI-PCEF provides a cost-efficient and access-agnostic solution to generate new revenues, without impacting mobile and fixed core networks.

Analyze . Control . Monetize

Based on the Vedicis Software Service Gateway (SSG) platform, Vedicis Deep Packet Inspection and Policy and Charging Enforcement Function (DPI-PCEF) empowers carriers to leverage the whole feature set of their Online Charging System with new subscriber's application- and location- aware use cases.

Benefits

 

Monetize data usage

 

Create new business models with Application based charging

Redirect traffic to operators’ portal for dynamic top-ups and added value services.

Improve subscriber’s quality of experience

 

Enforce application based policies to control congestion and prioritize  profitable traffic

Leverage access networks’ mechanisms for congestion mitigation by intelligently marking the traffic depending on multiple criteria.

 

Analyze network traffic

 

Analyze traffic patterns and subscribers’ behavior

Feed Big Data systems for analytics, revenue assurance, CEM and Fraud management systems.

Leverage real time processing to enhance Next best offer services.

Add new services with no impact to gateways

Packet gateways, either PGW, GGSN, BRAS or Wifi aggregators, are designed to efficiently handle subscribers and IP sessions but with a limited number of services.

Activating DPI or defining quota top-up packages usually lead to decrease gateways’ performance and impact subscribers’ quality of experience. Vedicis DPI-PCEF perfectly fit in differentiation demanding environments, providing added value services without impacting exiting core components.
