Pharos Policy Engine

About Pharos Policy Engine

The Pharos Policy Engine (PPE) is a Policy and Charging Rules Function (PCRF) that complements and enhances the capabilities of existing network elements, such as the PGW, OCS, and IMS Core.

The system enables you to deliver innovative and differentiated mobile data service products that are unattainable solely through an OCS.

It lets you create products with policies that manage the network resources subscribers can use for each service. These policies can be tailored based on various criteria, such as the data products subscribers have purchased, their locations, device types, selected APNs, radio access network types, and times of usage, among other things.

PPE helps network operators ensure efficient resource allocation, quality service delivery, and differentiated services.

Pharos has a suite of ready-to-use business products which we offer as bolt-on Application Service Modules (ASMs). ASMs are individual PCRF service applications—hosted on the base platform—that provide you with these differentiated data service products:

  • VoLTE Guaranteed Bitrates
  • Bitrate Control
  • Fixed Wireless Access
  • Fair Usage Policies
  • Social Bundles
  • Zero-Rates Services
