Intelligent policy and charging rule function (PCRF) restoration

摘要

A first device associated with an evolved packet core network receives a first update request from a second device associated with the evolved packet core network. The first update request is associated with a communication session previously provided between the first device and the second device, and the first update request is generated based on a voice/video request. The first device generates an update answer in response to the first update request, where the update answer includes a code requesting that the communication session be restored between the first device and the second device. The first device receives, based on the code, a second update request from the second device, where the second update request includes session information associated with the communication session. The first device restores, based on the session information, the communication session between the first device and the second device to create a restored communication session.

主权项

1. A method, comprising:
receiving, by a first device implementing a policy and charging rule function (PCRF) associated with an evolved packet core network, a first update request from a second device implementing a packet data network gateway (PGW) associated with the evolved packet core network,
the first update request being associated with a Gx communication session previously provided between the first device and the second device,the first update request being generated based on a voice request or a video request; generating, by the first device, an update answer based on being unable to identify the Gx communication session associated with the first update request,
the update answer including a code requesting that the communication session be restored between the first device and the second device; receiving, by the first device and based on the code, a second update request from the second device,
the second update request including session information associated with the Gx communication session previously provided between the first device and the second device; and restoring, by the first device and based on the session information, the Gx communication session between the first device and the second device to create a restored communication session.
