Policy Controller (PCRF)


  • Gx-interface towards GGSN, PDN-GW or DPI. This Diameter-based interface is used for policy and charging rules transfer to policy enforcement point (PE
  • Sp-interface (Diameter or XML) allows to receive subscriber-related information from subscriber profile repository. Such information may contain available bandwidth charging category, priorities, supported bearers (e.g. audio, video), historical information, age and other service-related data.
  • Rx-interface towards external applications which may require a capability to modify the parameters of subscriber’s Internet connection. This interface is Diameter-based, XML-based exchange is also supported
  • In 3GPP Release R8+ compliant networks PROTEI Policy Controller also supports Gxc-interface, used for policy and charging rules transfer to S-GW, and S9 interface, towards VPCRF in roaming scenarios.
