Method and apparatus for handling policy and charging control rule or quality of service rule modification failures

摘要

Methods and apparatuses are provided that facilitate handling failures in policy rule installation and/or related bearer modification procedures. A set of modified policy rules can be provided to a gateway for enforcement thereof and/or correlation with a bearer of a device. The gateway can attempt to install the modified rules and can utilize a credit control request (CCR)/credit control answer (CCA) exchange to notify of a status of the modified rule installation and/or related bearer modification. A policy charging and rules function (PCRF) can, thus, determine the status based on the CCR/CCA exchange. If the status indicates failure, the PCRF can revert to previous policy rules. In addition, an application function can be notified of the status.

主权项

1. A method, comprising:
providing, by a policy and charging rules function (PCRF), one or more modified policy rules to a gateway based at least in part on a bearer modification procedure, wherein the bearer modification procedure is configured to update one or more current policy rules of the gateway to the one or more modified policy rules by installing the one or more modified policy rules at the gateway; storing, by the PCRF, one or more previous policy rules in a memory based on providing the one or more modified policy rules to the gateway; determining, by the PCRF, whether the gateway has failed to install the one or more modified policy rules; and updating, by the PCRF, the one or more current policy rules of the gateway to the one or more previous policy rules stored in the memory based on the PCRF determining that the gateway has failed to install the one or more modified policy rules.
