PCRF Key Differentiation
(Figure: Policy and Charging Rules Function (PCRF) Key Differentiation Architecture)
  • Multiple Plan Association

    offers innovative multiple plan association feature that enables an operator to offer multiple data plans simultaneously to its subscribers. has developed innovative policy logic that meters for each service plan separate and attaches associated QoS for each subscriber. For example: a social network fan may be happy with a tiered data plan for general usage, but pay a bit extra for unlimited usage of Facebook and Twitter.

    In the above plan separate quota for general usage and facebook/twitter is maintained. Depending on the service used, intuitively decides the quota and QoS that is to be applied. NetVertex also gives the flexibility to top up on either of the plans in mid of the billing cycle. Thus enables operators expand the customer relationship through personalization and control, and expanding the monetization (revenue) opportunities for the service provider.

  • Smart Overload Prevention Mechanism

    NetVertex offers Smart overload prevention module, It offers three levels of protection against sudden spike in the network and graceful protection to handle high TPS requirement. This ensures NetVertex PCRF does not crash and subscriber experience for all the ongoing sessions is not deterred and usage of each session is properly metered with no revenue loss.
