PCC control at PCRF failure

摘要

A method for policy control in an infrastructure network comprising a Gateway (GW) an Access Function (AF), and at least one Policy and Charging Rules Function (PCRF) is provided. In some embodiments, the method includes: (a) the GW establishing a Gx or Gxx session in order to set the current PDN connection under PCC control, (b) the GW further providing information about the current PDN connection to a first PCRF, (c) the first PCRF performing authorization and policy decision based on the PDN connection information and sends it together with restoration instructions to the GW, (d) the GW when detecting that the first PCRF is not available, applying the restoration instructions, said instructions requiring the GW to try to regain PCC control and/or requiring the GW to gracefully delete the services associated with the PCC control.

1. In an infrastructure network comprising a gateway (GW), an access function (AF), and at least one policy and charging rules function (PCRF), a method for policy control, comprising:
the GW establishing a Gx or Gxx session in order to set a current packet data network (PDN) connection under policy and charging control (PCC) control; the GW providing information about the current PDN connection to a first PCRF, the first PCRF performing authorization and policy decision based on the PDN connection information received from the GW and sending a set of restoration instructions to the GW; the GW, when detecting that the first PCRF is not available, applying the restoration instructions, said restoration instructions requiring the GW to try to regain PCC control and/or requiring the GW to gracefully delete the services associated with the PCC control.
