Embodiment 1

[0081] Such as Figure 4 As shown, the 3GPP access P-GW is located in the visiting domain roaming scenario, S8 adopts PMIP protocol, BBERF is located in S-GW, PCEF is located in P-GW, the S9 session between VPCRF and HPCRF has been established, and the user initiates the second PDN of establishment. The HPCRF sends the PCC rule to the VPCRF through the S9 session, and the message contains the PDN information. After receiving it, the VPCRF sends the PCC rule to the PCEF (P-GW), and extracts the Qos rule from the PCC rule and sends it to the BBERF (S-GW). Specifically include the following steps:

[0082] 1. The user has established the gateway control session, IP-CAN session and S9 session corresponding to PDN1.

[0083]2. The user initiates the connection establishment of PDN2, first triggers the BBERF (SGW) to initiate the establishment of the gateway control session, and after the VPCRF receives the establishment message of the gateway control session, it judges that the ...

Embodiment 2

[0113] Such as Figure 5 As shown, it is a trusted non-3GPP access CMIP roaming scenario, the DSMIP protocol is used between the UE and the P-GW, the BBERF is located in the A-GW (A-GW is located in the visited location), and the PCEF is located in the P-GW (the P-GW is located in the home domain), the S9 session between the VPCRF and the HPCRF has been established, and the user initiates the establishment of the second PDN. The HPCRF sends the PCC rule to the VPCRF through the S9 session, and the message contains the PDN information. After receiving it, the VPCRF sends the PCC rule to the PCEF (P-GW). The HPCRF sends the QoS rule to the BBERF through the S9 session, which carries tunnel information (the prior art), and the BBERF distinguishes the PDN corresponding to the QoS rule according to the tunnel information. Specifically include the following steps:

[0114] 1. The user has established the IP-CAN session, gateway control session and S9 session corresponding to PDN1...

Embodiment 3

[0121] Such as Figure 6 As shown, it is 3GPP access, the P-GW of the second PDN connection is located in the home domain roaming scenario, S8 adopts the PMIP protocol, BBERF is located in the S-GW, PCEF is located in the P-GW, and the S9 session between VPCRF and HPCRF has been established , the user initiates the establishment of the second PDN. The HPCRF sends the QoS rules to the VPCRF through the S9 session, and the message contains the PDN information. VPCRF sends the QoS rule to BBERF (S-GW) after receiving it.

[0122] Specifically include the following steps:

[0123] 1. The user has established the gateway control session, IP-CAN session and S9 session corresponding to PDN1.

[0124] 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.

[0125] 3. After receiving the establishment message of the gateway control session, the VPCRF judges that the PDN is conn...

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...
