Embodiment 1

[0069] image 3 It is a flow chart of Embodiment 1 of the enhanced policy and charging control method of the present invention, as shown in image 3 As shown, this embodiment describes the IP-CAN session establishment process, and the specific steps are as follows:

[0070] In step S301, the gateway where the BBERF resides receives an IP-CAN session establishment request message, which carries information such as user ID and PDN ID.

[0071] In step S302, the BBERF sends a gateway control session establishment request message to the PCRF, and the message carries user identification, PDN identification, and the like. This message is used to request the establishment of a gateway control session.

[0072] Step S303, if the PCRF has no subscription information related to the user, the PCRF sends a subscription document request message to the SPR, and the message carries the user ID and PDN ID, etc. If there is user-related subscription information stored in the PCRF, step S305...

Embodiment 2

[0086] Figure 4 It is a flow chart of Embodiment 2 of the enhanced policy and billing control method of the present invention, as shown in Figure 4 As shown, this embodiment describes the termination process of the IP-CAN session initiated by the UE after the IP-CAN session is established based on the first embodiment. In this process, the gateway where the BBERF resides and the gateway where the PCEF resides uses PMIPv6 protocol to communicate. Specific steps are as follows:

[0087] In step S401, the gateway where the BBERF resides receives an IP-CAN session request message. The message carries the identifier of the IP-CAN session, such as the IP address of the IP-CAN session.

[0088] In step S402, the BBERF sends a gateway control session termination request message to the PCRF, and the PCRF identifies the relevant IP-CAN session and deletes the corresponding QoS rule.

[0089] In step S403, the PCRF returns a gateway control session termination confirmation message ...

Embodiment 3

[0105] Figure 5 It is a flow chart of Embodiment 3 of the enhanced policy and billing control method of the present invention, as shown in Figure 5 As shown, this embodiment describes the IP-CAN session modification process initiated by the AF. In this process, the gateway where the BBERF resides and the gateway where the PCEF resides communicate using the PMIPv6 protocol. Specific steps are as follows:

[0106] Step S501, AF sends application / service information to PCRF.

[0107] In step S502, the PCRF returns a confirmation message after saving the application / service information.

[0108] In step S503, the PCRF makes policy decisions according to subscription information, access information, service information and network policies. PCRF policies include PCC rules and corresponding QoS rules. If the issued PCC rules need to further implement policies and charging controls above four layers, the PCRF will also customize corresponding business execution rules. Service ...

Abstract

A method for enhanced Policy and Charging Control (PCC) is provided in the present invention, wherein a Traffic Detection Enforcement Function (TDEF) is set in PCC system. The method includes that a Policy and Charging Rule Function (PCRF) determines whether to perform the policy and charging control which is at the layers above the fourth layer on service data flows matching with the PCC rules or not, when it establishes the PCC rules; the PCRF indicates whether to perform the policy and charging control which is at the layers above the fourth layer on service data flows matching with the PCC rules or not, when it sends the PCC rules to a Policy and Charging Enforcement Function (PCEF), and if the PCRF indicates yes, the policy and charging control rules which are at the layers above the fourth layer performing on the service data flows are sent to the TDEF; the TDEF performs the policy and charging control rules which are at the layers above the fourth layer on the service data flows, and then returns the performing results to the PCRF. A system for enhanced policy and charging control, as well as a PCC system, is provided in the present invention. The present invention enables a multi-level, multi-latitude policy and charging control for the service data.

Description

technical field [0001] The present invention relates to enhanced policy and charging control (PCC, Policy and Charging Control) technology, in particular to an enhanced policy and charging control method and system, and a PCC system. Background technique [0002] The PCC system of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) is a functional framework that can be applied to multiple access technologies, for example, it can be applied to the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network), Global System for Mobile Communications (GSM, Global system for Mobile Communication) / GSM Data Enhanced Evolution (EDGE, Enhanced Data rates for Global Evolution) radio access network, interworking Wireless Local Area Network (I-WLAN) and Evolved Packet System (EPS, Evolved Packet System), etc. [0003] figure 1 It is a schematic...
