Embodiment 1

[0079] 2. The user initiates the connection establishment of PDN2, and first triggers the BBERF (SGW) to initiate the establishment of the gateway control session. After receiving the establishment message of the gateway control session, the VPCRF judges that the PDN connection is a local breakout scenario, and then hides the gateway control session (not to The HPCRF sends a session update), and directly returns a gateway control session establishment response message to the BBERF.

[0080] 3. The PCEF sends an IP-CAN session indication message to the VPCRF, which is used to indicate that an IP-CAN session is to be established, and requests the VPCRF for a PCC rule.

[0081] 4. The VPCRF initiates an S9 session update, and the message contains IP-CAN session information, PDN2 information, and the user IPv4 address corresponding to PDN2.

[0082]5. HPCRF formulates PCC rules according to IP-CAN session information, gateway control session information, user subscription informat...

Embodiment 2

[0111] 2. The user initiates the establishment of the PDN2 connection. Because it is a CMIP scenario, one gateway control session of the same user is associated with multiple IP-CAN sessions, so there is no need to establish a second gateway control session at this time. The PCEF sends an IP-CAN session indication message to the VPCRF to indicate that an IP-CAN session is to be established, and requests the VPCRF for a PCC rule.

[0112] 3. The VPCRF initiates an S9 session update, and the message contains IP-CAN session information, PDN2 information, and the user IPv4 / IPv6 address corresponding to PDN2.

[0113] 4. HPCRF formulates PCC rules according to gateway control session information, IP-CAN session information, user subscription information and operator-defined policies, and sends them to VPCRF in the S9 session update response. The PCC rules include PDN2 information, and the specific implementation method is the same as that in Embodiment 1.

[0114] 5. The VPCRF sen...

Embodiment 3

[0119] 1. The user has established the gateway control session, IP-CAN session and S9 session corresponding to PDN1.

[0120] 2. The user initiates the establishment of the PDN2 connection, and first triggers the BBERF (SGW) to initiate the establishment of the gateway control session.

[0121] 3. After receiving the establishment message of the gateway control session, the VPCRF judges that the PDN is connected to the P-GW in the home domain, and sends an S9 session update message (CCR message) to the HPCRF, carrying PDN2 information.

[0122] 4. The HPCRF formulates QoS rules according to the gateway control session information, user subscription information and operator-defined policies, and sends them to the VPCRF in the S9 session update response (CCA message). The rule contains the PDN information associated with the QoS rule.

[0123] The specific implementation method can be to extend the definition of QoS-Rule-Definition and carry PDN2 information:

[0124] QoS-Rule...

Abstract

The embodiment of the invention discloses a method for implementing strategy and charge control under a scene of multi-grouping data network. The method comprises that: VPCRF receives the PCC rule transmitted by HPCRF and S9 sub-conversation message correlated to the PCC rule; and the VPCRF transmits the PCC rule according to the S9 sub-conversation message. By carrying with the S9 sub-conversation message correlated to the PCC rule in S9 conversation message, S9 conversation can distinguish and process IP-CAN and establishment, modification and deletion of gateway control conversation under multi-PDN scenes, so that VPCRF can understand messages issued by HPCRF and sends the messages to correct PCEF or BBERF for execution, and VPCRF can submit PDN connection release messages to HPCRF, HPCRF releases corresponding PDN connection messages, thus avoiding invalid resource occupation and guaranteeing correct strategy formulation.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for implementing policy and charging control in a multi-packet data network scenario. Background technique [0002] During the evolution of the communication network to all IP, it is necessary to solve the end-to-end QoS problem in order to provide services that satisfy customers. IP networks can provide various services (such as multimedia calls, file downloads, web browsing, etc.), and different services have different requirements for QoS (including bandwidth, delay, packet loss rate, etc.), and the billing aspect The requirements are also different (for example, online billing or offline billing can be used, traffic billing or time billing can be used, etc.). [0003] In order to solve the above-mentioned problems related to QoS and charging, the 3rd Generation Partnership Project (3GPP) defines a policy and charging control (Policy and Cha...
