Embodiment 1

[0084] 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, what this embodiment describes is the IP-CAN session establishment process, and the specific steps are as follows:

[0085] 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.

[0086] 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 other information. This message is used to request the establishment of a gateway control session.

[0087] 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...

Embodiment 2

[0106] 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 IP-CAN session modification process initiated by TDEF after detecting new services according to the service detection rules. In this process, PMIPv6 is used between the gateway where BBERF resides and the gateway where PCEF resides. protocol to communicate. Specific steps are as follows:

[0107] In step S401, the TDEF detects the passing service data flow according to the service detection rules delivered by the PCRF, and detects a service that has not been reported to the PCRF before.

[0108] In step S402, the TDEF reports the detected service to the PCRF. The TDEF may report to the PCRF by reporting the identifier of the corresponding service detection rule or the identifier of the service preconfigured between the PCRF and the TDEF. At the same time, TDEF will also distribute a cha...

Embodiment 3

[0128] 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 process of realizing multi-level offline charging by PCEF and TDEF based on Embodiment 1 and Embodiment 2. The specific steps are as follows:

[0129] In step S501, the gateway where the PCEF resides needs to report charging information to the OFCS upon receiving the trigger.

[0130] In step S502, the gateway where the PCEF resides reports information to the OFCS, carrying the access network charging identifier, application charging identifier and bearer charging information.

[0131] In step S503, the OFCS saves the charging information.

[0132] In step S504, the OFCS returns a confirmation message.

[0133] Step S505, the gateway where the TDEF resides needs to report charging information to the OFCS upon receiving the trigger.

[0134] In step S506, the gateway where the TDEF resid...

Abstract

The invention discloses an enhanced policy and charging control method. A PCC (Policy Charge Control) system is internally provided with a TDEF (Traffic Detection Executing Function) which is connected between a PCRF (Policy and Control Reporting Function) and a charging system. The method comprises the steps: when formulating the PCC rule, the PCRF determines whether more than four layers of policy and charging control are carried out on service data streams matched with the PCC rule; when sending the PCC rule to a policy and control executing function (PCEF) entity, the PCRF indicates whether more than four layers of policy and charging control are carried out on the service data streams matched with the PCC rule; if yes, the PCRF sends the rule for carrying out more than four layers of policy and charging control on the service data streams to the TDEF; and the TDEF carries out more than four layers of charging on services, and provides corresponding charging information for the charging system. The invention discloses an enhanced policy and charging control system and the PCC system. The invention realizes multilevel and multi-latitudinal charging control on 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...
