Embodiment 1

[0098] Figure 12 is a flow chart of a session conflict handling method according to Embodiment 1 of the present invention, as shown in Figure 12 As shown, the figure is based on figure 2 The architecture diagram, the attachment flow chart when UE accesses 3GPP through PMIPv6 protocol, where GTP (GPRS Tunnel Protocol) is used between ePDG and P-GW, the process includes the following steps:

[0099] Step S1202-step S1228 are consistent with step S402-step S428.

[0100]Step S1230, now the H-PCRF has not received the S9 session establishment message sent by the step S1210, so the H-PCRF judges that the user's S9 session has not been established, so the H-PCRF sends a TER message to the V-PCRF (S9 session establishment trigger message), triggering the establishment of an S9 session and at the same time establishing an S9 sub-session for EPC-routed service policy control. The message carries information such as user ID, APN, and UE local IP address.

[0101] Step S1232: The V...

Embodiment 2

[0121] Figure 13 is a flow chart of a session conflict handling method according to Embodiment 2 of the present invention, such as Figure 13 As shown, the figure is based on image 3 The architecture diagram, the attachment flow chart when UE accesses 3GPP through PMIPv6 protocol, where GTP (GPRS Tunnel Protocol) is used between ePDG and P-GW, the process includes the following steps:

[0122] In step S1302, the UE accesses the BBF access system and performs 3GPP-based access authentication. BBF AAA interacts with 3GPP AAA Server through 3GPPAAAProxy (or, AAA Server further interacts with HSS) to complete EAP authentication.

[0123] In step S1304, the UE obtains the local IP address assigned by the BBF access network.

[0124] Step S1306, when IP Edge receives the trigger and supports policy interworking with PCRF, if the local policy indicates that NSWO policy control can be provided to the user, IP Edge sends a CCR message to V-PCRF, requesting to establish an S9a* ses...

Embodiment 3

[0130] Figure 14 is a flow chart of a session conflict handling method according to Embodiment 3 of the present invention, as shown in Figure 14 As shown, the figure is based on figure 2 The architecture diagram, the attachment flow chart when the UE accesses 3GPP through the DSMIPv6 protocol, the process includes the following steps:

[0131] In step S1402, the UE accesses the BBF access system and performs 3GPP-based access authentication. BBF AAA interacts with 3GPPAAA Server through 3GPPAAAProxy (or, AAA Server further interacts with HSS) to complete EAP authentication.

[0132] In step S1404, the UE obtains the local IP address assigned by the BBF access network.

[0133] In step S1406, triggered by step S1402 or step S1404, the BPCF is notified that the UE accesses through the BBF access network.

[0134] Step S1408, when BPCF receives the trigger and supports policy interworking with PCRF, if the local policy indicates that NSWO policy control can be provided to ...

Abstract

The present invention discloses a session establishment method, device and system, wherein the method includes: V-PCRF receives an S9 session establishment trigger message sent by H-PCRF, wherein the S9 session establishment trigger message is used to trigger the establishment of an S9 session and the first S9 sub-session, the first S9 sub-session is used for the evolution of packet core network routing service policy control; V-PCRF judges whether the S9 session has been or is being established; in the case of the judgment result being yes, V-PCRF indicates The H-PCRF S9 session has been or is being established. The invention solves the problem of conflicts in the process of establishing the S9 sub-session in the related art, and improves the stability of the system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for establishing a session. Background technique [0002] figure 1 It is a schematic diagram of the structure of the Evolved Packet System (EPS) evolved according to the 3rd Generation Partnership Project (3GPP) of related technologies, as shown in figure 1 As shown, the EPS network architecture in a non-roaming scenario includes the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN for short), the Mobility Management Entity (MME for short), ), Serving Gateway (S-GW for short), Packet Data Network Gateway (P-GW for short, also known as PDN GW), Home Subscriber Server (HSS for short) , Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF for short) entities and other supporting nodes. [0003] Among them, the PCRF is the core of Policy and Charging Control (PCC for...
