Embodiment 1
[0080] In this embodiment, the above-mentioned method 1 is used for charging, and the intermediate charging information of a session triggered by the handover process is used to correlate the charging information before and after the handover.
[0081] Figure 7 Be the flow chart of this embodiment, such as Figure 7 As shown, this embodiment mainly includes the following steps:
[0082] Step 701: The user equipment initially attaches to the IWLAN 3GPP IP access branch or the GPRS branch, and then establishes an IP-CAN session with the HA.
[0083] Step 702: The HA sends a charging data start request to the AAA Server, which includes Charging Id, RAT information, traffic and other charging information. If the user equipment initially attaches to the IWLAN 3GPP IP access branch, the PDG Charging Id and the corresponding RAT information are passed from the PDG to the AAA Server through the Wm / Wi interface; if the user equipment initially attaches to the GPRS branch, the GGSN C...
Embodiment 2
[0102] In this embodiment, the above-mentioned method 2 is used for charging, and in this embodiment, the identification information of the user service is used as the associated information.
[0103] Figure 8 Be the flow chart of this embodiment, such as Figure 8 As shown, the charging in this embodiment mainly includes the following steps:
[0104] Step 801: The user equipment initially attaches to the IWLAN 3GPP IP access branch or the GPRS branch, and then establishes an IP-CAN session with the HA.
[0105] Step 802: The HA generates the identification information of this user service, and sends a charging data start request to the AAA Server, which includes charging information such as Charging Id and RAT information, the identification information of this user service, and data traffic. If the user equipment initially attaches to the IWLAN 3GPP IP access branch, the PDG Charging Id and the corresponding RAT information are passed from the PDG to the AAA Server throug...

Abstract
The invention discloses a charging method and system. The method comprises the following steps: after user equipment (UE) is initially attached to a first access branch to establish a conversation with a home agent (HA), a charging data function (CDF) receives a charging data start request message transmitted by an authentication, authorization and accounting (AAA) server, wherein the charging data start request message carries first charging information; the CDF opens a charging data list of the HA to record the first charging information; when the UE is changed to be attached to a second access branch and continues the service, the CDF receives a charging data intermediate request message transmitted by the AAA server, wherein the charging data intermediate request message carries second charging information after the UE attached branch changes; and the CDF updates the opened charging data list, and records the second charging information in the charging data list. According to the invention, the charging data lists before and after switching the UE attached branches with continuous service can be associated, so that an operator can charge fees conveniently.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a charging method and system. Background technique [0002] figure 1 A schematic diagram is generated for an Interworked Wireless LAN (I-WLAN) architecture and existing charging information defined in the 3rd Generation Partnership Project (3GPP) wireless communication standards organization. [0003] Such as figure 1 As shown, a dual-stack mobile IP tunnel (DualStack Mobile Ipv6, DSMIPv6 for short) is established between a user equipment (User Equipment, referred to as UE) and a home agent (Home Agent, referred to as HA) for signaling and user data transmission. Before DSMIPv6 transmission is established, the user equipment can access the network by establishing an IPsec tunnel to a packet data gateway (Packet Data Gateway, referred to as PDG) or establishing a packet to a gateway GPRS support node (Gateway GPRS Support Node, referred to as GGSN). data protocol (...
