Problems solved by technology

In this way, the load on the forwarding plane equipment in the EPC network is too large and the burden is too heavy
Moreover, EPC itself has introduced a number of new technologies, such as distribution technology. Although these introduced new technologies can make the network more comprehensive, but before these technologies can be reliably applied in the EPC network, the EPC network that introduces the new technology needs to be tested and tested. The deployment, testing and deployment cycle is too long, and the cost is relatively expensive

Embodiment Construction

[0095] The embodiment of the present invention records a charging implementation method based on the software-defined core network SDN EPC network, such as figure 1 As shown, the method includes:

[0096] Step 11: The controller receives the charging rule sent by the charging rule generator, and binds the corresponding relationship between its own flow table and the charging rule.

[0097] Here, the charging rule generator sends the charging rule to the controller after receiving the charging rule request message from the controller.

[0098] Step 12: The controller sets entries in the flow table bound with the charging rule, and sends the set flow table to the UGW.

[0099] Here, according to the statistical requirements of the user's business data flow, such as counting the flow or duration of the data packets of the business flow and then charging the service, set the payload counter, timer, Table items such as traffic threshold, duration timer, and monitoring timer, and ...

Abstract

The present invention discloses a billing implementation method based on a software defined networking evolved packet core (SDN EPC) network, said method comprising: a controller receiving billing rules sent by a billing rule generator, and binding the corresponding relationship between its own flow table and the billing rules; the controller engaging in table-entry setting for the flow table having billing rules bound thereto, and sends the post-setting flow table to a universal gateway (UGW); the controller receiving statistical results for the operations-occupied flow rate and / or occupation duration, which are based on the flow table and which are reported by the UGW, and, in accordance with the statistical results and the flow table billing rules, engaging in the billing of operations. The present invention also discloses an SDN EPC network-based billing implementation system.

Description

technical field [0001] The present invention relates to communication billing technology, in particular to a billing implementation method and system based on Software Defined Network (SDN, Software Defined Network) and Evolved Packet Core Network (EPC, Evolved Packet Core). Background technique [0002] It has always been a problem faced by major operators to realize user's communication billing safely and effectively. In the prior art, when an EPC network charges a user's communication fee, a packet data gateway (PGW, PDN Gateway) and a serving gateway (SGW, Serving Gateway), as forwarding plane devices in the EPC network, are integrated with a charging trigger function ( CTF, Charging Trigger Function), charging data function (CDF, ​​Charging Data Function) and charging gateway (CGF, Charging Gateway Function) functions, using these functions can complete the collection of charging information and credit control, and then reliably realize the User's offline charging or o...
