Policy decision-making functional entity, home gateway and method and system for controlling quality of service

Abstract

A strategy determining function entity, Home Gateway, service quality controlling method and the system thereof have been disclosed. The service quality controlling method comprises the steps of: receiving the service request or the service quality strategy rules request sent by Home Gateway or by Home Gateway collocation unit; performing authorization and determination to the service request, determining the service quality strategy rules corresponding to the service requested by the service request based on the service identifier carried by the service request; or performing authorization and determination for the service quality strategy rules request, determining the service quality strategy rules corresponding to the service controlled by the Home Gateway based on the Home Gateway position information, Home Gateway identifier and the terminal identifier carried by the service quality strategy rules request; sending the determined service quality strategy rules to the Home Gateway which is used for distributing the service quality resource to the service request. The embodiments of the present invention solve the problem of the dynamic service quality control in Customer Premises Network.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a policy decision-making functional entity, a home gateway, and a quality of service control method and system. Background technique [0002] Next Generation Network (NGN, Next Generation Network) is a service-driven network, and the transport control layer of the NGN network provides user access and service access respectively. The Network Attachment Control System (NACS) focuses on user access, and its functions include: terminal access management, user access management, network resource control interface, and service access control interface management, etc. User access management has nothing to do with the terminal, it is the logical name of the subscriber entity, it needs authentication and billing, and it is the core of the user access part. The Resource Admission Control System (RACS) focuses on service access, and its functions in...

Problems solved by technology

[0013] The policy-based home gateway service traffic identification system and method provided by the prior art is only suitable for the static configuration of multiple service QoS resources in the home gateway (reserving QoS resources for the service regardless of whether the user requests the service). The service requests such as IPTV unicast / multicast service requests cannot realize the dynamic allocation and adjustment of QoS resources when the required service QoS resources are insufficient
