[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...

Abstract

A method and system for inter-domain negotiation of end-to-end service quality. A policy enforcement point sends a policy decision request message to a policy decision layer; The point sends the Go port message containing the information required for the bearer resource request message to the external network; after the policy enforcement point receives it, it selects an external network in the OFFPATH negotiation mode, obtains the address of its resource controller and the protocol it supports, Obtain and send the bearer resource request message of the protocol supported by the external network resource controller according to the Go port message; the external network resource controller returns a bearer resource response message to the policy enforcement point; after the policy enforcement point receives the response message, if If the negotiation is successful, execute according to the policy decision of the policy decision-making layer, and return a policy execution report to the policy decision-making layer. The invention makes the network construction simple, and avoids the inconsistency of the connection between the policy execution point and the policy decision-making layer and the external network.

Description

technical field [0001] The present invention relates to the service quality guarantee of the third generation mobile communication system, more specifically, relates to the inter-domain negotiation method and system of the core network side end-to-end service quality. Background technique [0002] The technology involved in the present invention is based on the following two technical foundations: intra-domain and inter-domain end-to-end QoS guarantee systems. QoS (Quality of Service) is an index used to measure resource requirements such as bandwidth and delay of services. [0003] End-to-end quality of service guarantee system within the domain: the domain here includes the GPRS packet domain, or the network scope that uses IP networks such as GPRS as the access network and interacts with the IMS (IP Media Streaming Subsystem) network and PSTN network. The QoS guarantee system completes resource guarantee through policy decision and policy execution in such a domain to me...
