Resource acceptance control method, network apparatus and network system

Abstract

An embodiment of the invention provides a resource admitting control method which includes: a net attachment control unit NACF sends service request to a resource admitting control unit after receives an authentication request sent by a mobile user for triggering the RACF actualizing resource admitting control to a transmitting net. A technique scheme provided by the embodiment has advantages that distributing speed of resource is rapid, mobile ability of operation is supported, and conversation continuity and better QoS quality can be ensured simultaneously.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a resource admission control method, a network device and a network system. Background technique [0002] In the next generation network (Next Generation Network, NGN), the service control and transmission functions are separated, and in order to ensure the service quality (Quality of Service, QoS) of the service, the concept of resource admission control is introduced. The Resource Admission Control Function (RACF) is located at the transport layer, between the service control layer and the bearer transport layer such as figure 1 , through the implementation of resource admission control, shield the specific details of the transport network from the service control layer, support the separation of service control and transport functions, and perceive the resource usage of the transport network downwards, and ensure the correct and reasonable use of the transport network t...

AI Technical Summary

Problems solved by technology

[0011] 1. In the solution proposed in the prior art, after the mobile user is authenticated, the mobile user initiates a request to join the SCF service, and the SCF triggers the resource admission control, which slows down resource allocation and release.

[0012] 2. In the prior art, after the mobile user switches the network, the SCF sends a service request to RACF2, and RACF2 executes the corresponding policy in the access network 2. Therefore, the QoS of the service cannot be guaranteed during the switching process, so the continuity of the session cannot be guaranteed sex
