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.
