Service processing method and system, and policy control and charging rules function

摘要

A service processing method, a service processing system, and a PCRF entity are disclosed to overcome this defect in the prior art: The prior art is unable to handle services discriminatively according to the policy context information when different services require the same QoS level. The method includes: receiving bearer priority information from a PCRF entity, where the bearer priority information includes: bearer priority information of a service data stream, bearer priority information of an IP-CAN session, and/or bearer priority information of an IP-CAN bearer; and handling services according to the bearer priority information. In the embodiments of the present disclosure, the policy context information is converted into bearer priority information so that the PCEF handles services according to the bearer priority information. In this way, different services that require the same QoS level are handled discriminatively according to the policy context information.

主权项

1. A service processing method, comprising:
obtaining by a Policy Control and Charging Rules Function (PCRF) entity, which includes a processor, policy context information of a service data stream, wherein the policy context information of the service data stream comprises at least one of: service type, service priority, user priority, and custom-defined priority; generating by the PCRF entity, bearer priority information on the service data stream according to the policy context information, wherein the bearer priority information designates a priority level of the service data stream within a bearer layer at a QoS level; and sending by the PCRF entity, the bearer priority information to a Policy and Charging Enforcement Function (PCEF) entity for discriminative handling the service data stream within the bearer layer along with other service data streams which are at the same QoS level; wherein the bearer priority information is set in a bearer priority information element; wherein the bearer priority information element is set into a bearer priority message directly or set into an existing information element; wherein a type of the bearer priority message is a Credit Control Answer (CCA) message, or a Re-Authentication Request (RAR) message; and wherein a type of the existing information element is a Charging-Rule-Definition Attribute Value Pair (AVP) information element, or an Authorized-Quality of Service (QoS) AVP information element; wherein discriminatively handling the service data stream within the bearer layer along with the other service data streams comprises:
processing the data stream along with the other service data streams within the bearer layer which are at the same QoS level according to the bearer priority information, wherein precedence is given to a service data stream having a higher bearer priority level.
