[0067] Such as image 3 As shown, in the network architecture of the system, the gateway between PDF and the resource controller of the external network is canceled, and the interactive path is changed to be completed by two-way forwarding through PEP.
[0068] In the information configuration module of the PEP, the routing information of the external network has been configured originally. In order to complete the forwarding function of the message between the PDF and the resource controller of the external network, the present embodiment also needs to configure the QoS negotiation mode (such as OFFPATH) of the external network in this unit. mode), addressing information such as the address or network segment of the external network resource controller, and the type of protocol supported by the resource controller.
[0069] In addition, PEP also needs to add a QoS negotiation processing part, including: a message identification module, which is used to judge whether the messa...

[0087] In fact, the service information contained in the bearer resource request message of the Gout between the original process PDF and the external network resource controller can be found in the policy decision message of the Gout. Therefore, this embodiment does not change the message of the Gout. Instead, a PDF proxy module (hereinafter also referred to as PDF proxy, which is actually the QoS negotiation processing part in the PEP) is set in the PEP, and the information in the policy decision message is extracted by this module to organize the content of the bearer resource request message, and After receiving the response from the external network resource controller, it is judged whether the negotiation is successful and whether another external network is to be selected. That is, the PDF agent in the PEP completes the bearer resource negotiation with the resource controller of the external network instead of PDF, so as not to affect the process in the original domain a...
