Problems solved by technology

Typically, each IP edge device (such as Broadband Network Gateway (BNG) / Broadband Access Server (BRAS) can support 5000 access nodes (AN), each AN supports 1000 lines of digital subscriber line (DSL), each DSL supports 1 PPP session and 3 IP sessions, and each BNG / BRAS will support the processing of 20,000,000 subscriber sessions. Large; and the real-time processing performance load of BNG / BRAS is high, and the processing time is prolonged, which will affect the performance of real-time detection

Abstract

The invention provides an agency device, which comprises a session survival detection switch processing unit for switching between a first conversion survival detection supported by a first communication opposite terminal and a second conversion survival detection supported by a second communication opposite terminal. The invention also provides another agency device, which comprises a conversion group survival detection switch processing unit for performing middle agent of conversion group survival detection between the conversion group communication opposite terminal and the conversion communication opposite terminal. Accordingly, the invention also provides session survival detection method and a network system based on the two agency devices. The agency devices can realize the mutual conversion between different session survival detection mechanisms, perform survival detection relative to the conversion group, and reduce the message flow rate of the session survival detection.

Description

technical field [0001] The invention relates to the access network technology of a mobile communication network, in particular to a proxy device, a session survival detection method and a session survival detection network system. Background technique [0002] In the access network, an IP session (session) represents a network access connection session associated with a subscriber (Subscriber) or user (User) IP address, and the IP session is related to the point-to-point protocol PPP (Point-to-Point Protocol) sessions are peer-to-peer. Usually, IP sessions and PPP sessions are collectively referred to as subscriber sessions. Subscriber sessions are usually terminated on IP edge devices (IP Edge devices), that is, subscriber sessions are between user terminals and IP edge devices. An established session connection is used for network management of user access to the network, such as billing and status. [0003] Multiple mechanisms can be used for the survival detection of th...
