Problems solved by technology

[0006] Currently for the above described figure 1 , figure 2 and image 3 This enhanced architecture supports non-3GPP network access to EPC. It is known that the P-GW will generate charging information through a specific charging interface. However, when the visited network and the home network belong to different operators, when the P-GW is located in the Network, when the ePDG is located in the access network, it is impossible to complete the clearing and reconciliation of different operator networks only by relying on the billing of the P-GW

Embodiment Construction

[0043] The basic idea of ​​the present invention is: after the billing logic function entity CTF receives the evolution packet data usage of the non-3GPP access network access network sent by the network element responsible for the non-3GPP access network access in the EPC, it generates The charging information is sent to the offline charging gateway and / or the online charging system for charging; the charging system performs charging based on the charging information of the evolved packet data.

[0044] The above CTF is specifically set in the ePDG, and / or set outside the ePDG. The above CTF is set outside the ePDG, specifically: the CTF is set in 3GPP AAA or in other network elements.

[0045] CDF and CGF are set in the above-mentioned offline charging gateway.

[0046] The above-mentioned CDF and CGF can be set in the ePDG; when the CDF and CGF are set in the ePDG, the ePDG and the offline charging gateway are set together.

[0047] Or, the CDF is set in the ePDG, and the...

Abstract

A charging method for an Evolved Packet Core supporting non-3GPP accessing is provided by the present invention, which comprises: a Charging Triggering Function (CTF) generates charging information based on the evolved packet data usage of the non 3rd Generation Partnership Project (3GPP) accessing network, and sends to an offline charging gateway or an online charging system for charging. A charging system for the Evolved Packet Core supporting the non-3GPP accessing is provided by the present invention simultaneously, which can realize the aforementioned method. The present invention realizes charging based on the data flow for users which access through the non-3GPP accessing network.

Description

technical field [0001] The present invention relates to charging technology, in particular to an evolution packet core network charging method and system supporting non-third generation partnership project (3GPP, 3rdGeneration Partnership Project) access. Background technique [0002] Long Term Evolution (LTE, Long Term Evolution) is expected to meet the needs of the broadband market mainly through fixed technologies in the near future. In order to adapt to the speed increase of the wireless side, further evolution of the core network architecture has become a key topic of 3GPP organization research. It is also an important content of the "System Architecture Evolution (SAE, System Architecture Evolution) project, also known as the Evolved Packet Core Network (EPC, Evolved Packet Core) or EPC. The Evolved Packet System (EPS, Evolved Packet System) is the evolution of the future mobile network Direction, the main features include: comprehensive packetization, providing pure p...
