Embodiment Construction

[0055] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0056] Main idea of ​​the present invention is:

[0057] In the roaming scenario, the service-based policy decision-making function of the home site and the service-based policy decision-making function of the visited site are proposed to solve the problem of cross-domain QoS policy decision-making by exchanging information.

[0058] This method includes the QoS policy negotiation process between the service-based policy decision-making function of the visiting place and the service-based policy decision-making function of the home place: the service-based policy decision-making function of the visiting place can compare the service-based policy from the home place according to its own local policy The QoS information of the decision-making function is modified, but the modification result needs to be fed back to the service-based policy dec...

Abstract

The present invention provides a resource receiving control method which is used in communication field. The method includes: calling region module based on operation strategy decision function processes resource strategy decision according with received operation request message and user subscription message, and sends resource request message to visiting region module based on operation strategy decision function; said visiting region module based on operation strategy decision function processes authentication check for said resource request message, and sends resource request answering message to said calling region module based on operation strategy decision function; said resource request answering message includes service quality message modified by visiting region module based on operation strategy decision function, or feedback acceptable service quality message in rejection; said calling region module based on operation strategy decision function makes ultimate decision; the invention also provides a system used in said resource receiving control method and solves cross-realm QoS strategy decision problem.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for resource admission control in an optimized roaming scenario. Background technique [0002] NGN (Network Generation Network, Next Generation Network) is a hot research topic in the field of current communication standards. It adopts packet technology such as IP as a 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: VoIP, video conferencing, multimedia distance learning, and video on demand), these services require the communication network to provide efficient end-to-end quality of service (Quality of Service). , QoS) support; at the same time, users have higher and higher requirements for network service quality. Therefore, how to provide end-to-end QoS is one of the core issues of NGN. [0003] TISPAN (Telec...
