Resource admission control method and system

Abstract

The invention proposes a resource admission control method applied in the field of communications, including: a home location policy decision functional entity module, according to the received service request message and signing information of users, makes resource policy decision and transmits resource request message to a visited place policy decision functional entity module; the visited place policy decision functional entity module performs authorization examination to the resource request message, and transmits a resource request response message to the home location policy decision functional entity module; and then the home location policy decision functional entity module makes the final strategy decision. The present invention also provides a resource admission control system, which ensure that the home location policy decision functional entity module and the visited place policy decision functional entity module interchanges information under roaming scene, in order to resolve cross-border quality of service QoS strategy decision-making problem.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource admission control method and system in a roaming scene. Background technique [0002] NGN (Network Generation Network, next-generation network) is a hot research topic in the field of current communication standards. It uses IP and other packet technologies as the bearer network technology to integrate fixed communication and mobile communication. NGN can provide richer multimedia services, such as emerging services with real-time requirements (such as video conferencing, multimedia distance learning, video on demand, etc.), these services require the communication network to provide efficient end-to-end quality of service (QoS, Quality of Service ) support; at the same time, users have higher and higher requirements for network service quality. Therefore, how to provide end-to-end QoS will be one of the core issues of NGN. [0003] The ITU-T is a telecommunication ...
