Prepaid Charging Front-end

In recognition of the importance of real-time charging, the 3GPP now refers to "on-line" and "off-line" charging rather than "pre-" and "post-paid" charging and defines a functional separation between the charging-trigger function (CTF) of a network and the online charging system (OCS).   The CTF itself is necessarily tightly-coupled with the service being delivered.

These applications can be used for both pre and post-paid subscribers in cooperation with a real-time charging system.  This reduces the duplication of services and helps both retain subscribers and removes a barrier to service use.

The Online Charging Front End application combine the charging interfaces and CTF with a powerful session-control (and call-control) to deliver online charging enabled services within this new framework.  This may be achieved by inserting functionality in-front of an existing service in order to generate the required charging triggers, by hosting and executing new services directly within it’s own application server environment, or via a combination of both.

Several OpenCloud operator customers have implemented split-architecture prepaid charging systems using Rhino to deliver the call control applications.  Besides the standard call, messaging and data control and metering, they have implemented:

  • Prepaid balance replenishment
  • Balance query by USSD and SMS
  • Balance transfer
  • Pay for me
  • Premium content charging
