Embodiment 1

[0084] Picture 10 It is a flowchart of the method for obtaining a charging policy according to the first embodiment of the present invention Figure one ,Such as Picture 10 As shown, when a user attaches from a WLAN for the first time and accesses an EPC with a trusted WLAN access network, the user signs a contract in the HSS during the Extensible Authentication Protocol (EAP) access authentication process The charging strategy is transferred to TWAN, and TWAP in TWAN passes the charging strategy to P-GW in the subsequent GTP establishment process through TWAG.

[0085] Step S1002: The UE and the WLANAN execute a non-3GPP-specific access procedure to establish an L2 connection.

[0086] Step S1004: WLANAN sends an EAP request identity (identity) message to the UE, requesting to obtain the identity of the terminal. Start the EAP authentication process.

[0087] Step S1006: The UE returns an EAP response / identity to the WLAN AN, which carries the identity of the terminal (the identi...

Embodiment 2

[0110] Picture 11 It is a flowchart of the method for obtaining a charging policy according to the second embodiment of the present invention Figure II ,Such as Picture 11 As shown, after the user accesses from 3GPP, he switches to the WLAN coverage area and uses a trusted WLAN access network to access the EPC. During the EAP access authentication process, the user signs in the HSS based on the access network The charging strategy of the type is sent to the TWAN, and the TWAP in the TWAN passes the charging strategy to the P-GW in the subsequent GTP establishment process through the TWAG.

[0111] Step S1102: The UE accesses from 3GPP, and there is a GTP tunnel on the S5 interface.

[0112] Step S1104: The UE discovers a trusted WLAN access system, and decides to switch from the attached 3GPP access to the discovered trusted non-3GPP access system.

[0113] Step S1106: The UE executes the access authentication and authorization process of the trusted non-3GPP access system. The 3...

Embodiment 3

[0130] Picture 12 It is a flowchart of the method for obtaining a charging policy according to the third embodiment of the present invention Figure three ,Such as Picture 12 As shown, when the charging policy based on the access network type at the HSS changes, the HSS informs the P-GW of the changed charging policy.

[0131] Step S1202: The charging policy based on the access network is changed at the HSS, and the HSS informs the AAA user that the charging policy based on the access network has changed through a subscription information update request message, and AAA informs the TWAP in the TWAN of the change at the same time.

[0132] Step S1204: After receiving the charging policy change request based on the access network in the TWAN, the TWAP returns an update response.

[0133] Step S1206: At the same time, the TWAP in the TWAN sends a bearer modification command through TWAG to inform the P-GW of the changed charging policy.

[0134] Step S1208: The PGW performs new charging...

Abstract

Disclosed are a charging control method and device, the method comprising: a packet data network gateway acquires from a home subscriber server a charging policy based on the type of an access network; the packet data network gateway charges, according to the charging policy, the UEs accessing from different access networks. The present invention solves the problem in the prior art that the charging policies cannot be differentiated when users access an EPC via different access networks, and provides technical support for the charging control of different types of access networks, thus improving the application scope and flexibility of the charging control.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a charging control method and device. Background technique [0002] figure 1 It is a structural diagram of an evolved packet system based on related technologies, such as figure 1 As shown, the EvolvedPacket System (EPS) of the 3rd Generaion Partnership Project (3GPP) includes the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network). E-UTRAN), Mobility Management Entity (MME for short), Serving Gateway (S-GW for short), Packet Data Network Gateway (P-GW for short), home user server (Home SubscriberServer, referred to as HSS). [0003] Among them, MME is responsible for mobility management, non-access stratum signaling processing and user mobility management context management and other control plane related work; S-GW is an access gateway device connected to E-UTRAN, in E-UTRAN and P-GW forwards data and is responsible for ca...
