Problems solved by technology

[0024] The existing RACS functional architecture system cannot support the description of the relationship between flows, so it cannot support the resource management and admission control of flows that have specific relationships with each other
The management of these relationships by AF is complex and inefficient, and may cause waste of bearer bandwidth

Embodiment Construction

[0055] The core of the present invention is that the service control layer in the NGN architecture initiates a resource request with flow relationship indication information to the bearer control layer, and the bearer control layer controls a group of flows according to the flow relationship indication information so as to realize the QoS for a specific flow control.

[0056] In the present invention, each stream in a group of streams to be transmitted has a specific relationship, such as a multicast relationship, an anycast relationship, and the like. This specific relationship between individual streams is recorded in the stream relationship information transmitted with the set of streams. The bearer control layer exerts control on each network element of the data bearer layer according to the flow relationship information, so as to realize the QoS control and management of this group of specific flows.

[0057] The so-called flow relationship refers to the relationship bet...

Abstract

The invention relates to a method for implementing QoS management of a group of specific flows, and its kernel comprises: firstly, in the next-generation network (NGN) structure, service control layer sends a resource request to carrying control layer, where the resource request message carries flow relation indication information for indicating the relation between service flow corresponding to the request and other service flows; then, the carrying control layer makes resource policy decision on the service flow according to the flow relation information and specific flow information and issuing the resource policy to data carrying layer, and the data carrying layer manages QoS of the service flow. And it adds flow relation information into flows with specific relation, and RACS explains the flow relation information and controls service flows according to the flow relations, implementing QoS control and management and saving network resources.

Description

technical field [0001] The invention relates to the communication field, in particular to a controllable and manageable QoS method for a group of specific flows supporting the next generation network (NGN). Background technique [0002] NGN is a packet-based network that can provide telecommunication services; utilize multiple broadband capabilities and QoS-guaranteed transmission technologies; its business-related functions are independent of its transmission technologies. NGN enables users to freely access different service providers; NGN supports general mobility. [0003] The basic features of NGN are as follows: packet transmission; control function is separated from bearer, call / session, application / service; Real-time, streaming, non-real-time and multimedia services); end-to-end QoS and transparent transmission capabilities; interworking with traditional networks through open interfaces; universal mobility; allowing users to freely access different service providers;...
