Problems solved by technology

Therefore, the original online billing method performed by SAE-GW is not applicable to the EPC network under the combination of NFV and SDN, and the data traffic of the EPC network has the risk of malicious overdraft

Embodiment 1

[0127] Figure 5 It is a flowchart of a method of a specific embodiment of the present invention, such as Figure 5 Shown, including:

[0128] Step 500: The terminal initiates an access creation session request to the SAE-GW in the Controller (SAE-GW is a virtual device in the Control), and creates a default bearer.

[0129] Step 501: The SAE-GW generates the TEIDC of the control plane, selects an OpenFlow switch, and initiates a bearer creation request to it (carrying TEIDC, used to bring back the response from the opposite end).

[0130] It should be noted that if the SAE-GW is only used as an SGW, this step is also required, but the OpenFlow switch is only responsible for forwarding user service data packets to the OpenFlow switch designated by the PGW. This specific situation is not repeated here;

[0131] Step 502: The OpenFlow switch generates and returns TEIDU to the Controller in response to the bearer creation request of the Controller. So far, an association relationship h...

Abstract

The invention discloses a method and a system for realizing online charging. The method comprises the steps of acquiring accumulated flow of a data message which corresponds with each rate for aiming at each user; and performing online charging according to the preset rate and the accumulated flow of the data message that corresponds with each rate. According to the method of the invention, online charging is performed through the rate which is preset by an OpenFlow switch for realizing online charging and the accumulated flow of the data message that corresponds with each rate, and online charging of the EPC network is realized on condition that the NFV is combined with SDN. Furthermore, through setting the rate in a service list and adding a flow list into the service list of the corresponding rate, online charging is realized.

Description

Technical field [0001] The invention relates to a mobile communication system, in particular to a method and system for realizing online charging by combining mobile core network network function virtualization (NFV) and software-defined network (SDN). Background technique [0002] The current Evolved Packet Core (EPC, Evolved Packet Core) online charging is implemented by the system architecture evolution gateway (SAE-GW, System Architecture Evolution-gateway) network element docking with the Online Charging System (OCS, Online Charging System) server, Among them, SAE-GW is a network element that combines a serving gateway (SGW) and a public data network gateway (PGW). figure 1 It is the basic topology diagram of the existing mobile EPC network, such as figure 1 As shown, SAE-GW not only undertakes the task of forwarding on the data plane (solid line connection part), but also undertakes the task of forwarding on the control plane (dashed line connection part), and the online cha...
