Embodiment Construction

[0082] The core idea of ​​the present invention is: In order to realize the QoS control of the access network, the concept of "two-layer session" is introduced, so as to establish a logical end-to-end connection between the user and the IP Edge, and manage the resource and Policies are used to control the QoS of users in the access network and simplify the control mechanism. "Layer 2" refers to the IP layer (layer 3), the part of the protocol stack between the IP layer and the physical layer, such as ATM PVC, Ethernet MAC, etc. A "Layer 2 session" refers to a session that can be indexed by one or more Layer 2 information during session connection, and the Layer 2 information that identifies a Layer 2 session becomes a Layer 2 session identifier. "Service session" refers to the session directly managed by the service, and its identifier becomes "service session identifier", which is also used as an index of all flow information and quality of service attributes of the session, ...

Abstract

This invention relates to an access network session control system including: an automatic collocation server and a loading control subsystem, in which, the automatic collocation server is used in receiving the registration request of two-layer session ability of users and assigning two-layer session identifications to the service or applying for a two-layer session identification to the subsystem, which negotiates with the automatic assigning server about the identification and receives the user information and identification sent by the server to find out IP edge devices and access network device based on the user information and sets two-layer session and resource distribution based on the identification and default priority of the user, which can set up an end to end connection logically between users and IP Edge.

Description

technical field [0001] The invention relates to a communication service quality control system, in particular to an access network session control system and method. Background technique [0002] International standardization organizations such as the European Telecommunications Standardization Institute (ETSI) and the International Telecommunication Union's Telecommunication Standardization Sector (ITU-T) all believe that the next-generation telecommunication network is built on an IP or packet switching network. With the continuous development of technology, the technical trend of providing triple play on IP is becoming more and more obvious. However, the original intention of the design of the IP network is only to solve the interconnection problem of devices located in different places, which has great openness. It is also because of its openness that Internet technology has developed rapidly in just ten years, has basically spread to families, and has become an indispe...
