Service processing method and system, and policy control and charging rules function
First Claim
1. A service processing method for discriminatively handling a service data stream from a plurality of service data streams, comprising:
- obtaining by a Policy Control and Charging Rules Function (PCRF) entity, policy context information of a service data stream, wherein the policy context information of the service data streams 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;
sending by the PCRF entity, the bearer priority information to a Policy and Charging Enforcement Function (PCEF) entity for discriminative handling within the bearer layer along with other service data streams which are at the same QoS level, wherein the PCEF entity performs discriminative handling function by;
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 priority level; and
adding 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.

Abstract
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 invention, 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.

10. A service processing system for discriminatively handling service data streams from a plurality of service data streams, the service processing system comprising:
a Policy Control and Charging Rules Function (PCRF) entity including a processor and a memory, enabled to; obtain policy context information, which comprises at least one of;
a service type, a service priority, a user priority, and a custom-defined priority;generate bearer priority information 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; send the bearer priority information to a Policy and Charging Enforcement Function (PCEF) entity;
wherein;
the PCEF entity is enabled to handle within the bearer layer along with other service data streams 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; andadd 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. - View Dependent Claims (11, 12)

13. A Policy Control and Charging Rules Function (PCRF) entity including a processor and a memory, comprising:
-
an obtaining unit, enabled to obtain policy context information, comprises at least one of;
a service type, a service priority, a user priority, and a custom-defined priority;a generating unit, enabled to generate bearer priority information 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; a sending unit, enabled to send the bearer priority information to a Policy and Charging Enforcement Function (PCEF) entity, such that the PCEF entity discriminately processes the data stream along with 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; and an adding unit, enabled to add 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.
