Problems solved by technology

In the prior art, there is no specific method for establishing a Gxd session between the PCRF and the BNG, resulting in that when the UE accesses the BNG, the BNG cannot obtain the PCC rule information from the PCRF, thereby failing to implement policy control over the access UE

Embodiment Construction

[0027] In the embodiment of the present invention, when the Gxd session between the BNG and the PCRF needs to be established, the PCRF initiates the Gxd session establishment process to the BNG to ensure the establishment of the Gxd session between the BNG and the PCRF.

[0028] The method embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] see figure 2 As shown, the PCRF provided by the embodiment of the present invention initiates the method for establishing a Gxd session, including the following steps:

[0030] Step 201: When a UE accesses a BNG, the PCRF receives control information related to the BNG address information.

[0031] Step 202: The PCRF obtains the address information of the BNG according to the control information.

[0032] Step 203: The PCRF initiates a Gxd session establishment process to the BNG.

Abstract

The invention discloses Gxd session establishing method, device and system. The method comprises the following steps: when UE (User Equipment) is accessed into a BNG (Broadband Network Gateway), PCRF (Policy and Charging Rules Function) receives control information related to the BNG address information; the PCRF acquires the address information of the BNG according to the control information; and the PCRF initiates a Gxd session establishing process to the BNG. In the invention, when Gxd session needs to be established between the BNG and the PCRF, the PCRF initiates the Gxd session establishing process to the BNG. Therefore, the invention achieves the purpose that the PCRF initiates the Gxd session establishing process to the BNG, thereby ensuring establishment of the Gxd session between the BNG and the PCRF.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device and system for establishing a Gxd session. Background technique [0002] In the converged policy management and billing architecture, the gateway entity in the Broadband Forum (BBF) network, Broadband Network Gateway (BNG) / Broadband Remote Access Server (Broadband Remote Access Server, BRAS) and Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF) are connected through the Gxd interface, and the PCRF sends policy and charging control (Policy and Changing Control, PCC) rule information to the BNG through the Gxd interface. [0003] figure 1 For a schematic diagram of the integrated policy management and charging architecture in the prior art, see figure 1 As shown, a user terminal (User Equipment, UE) 11 is connected to a local gateway (Residential Gateway, RG) 14 through a wireless local area network (Wireless Local Area Networks, WLAN) access...
