Embodiment 1
[0053] The present invention relates to a distributed user access system. The system includes the following network elements: a flow controller (Flow Controller, FC for short), and multiple User Access Gateways (UAG for short). The distributed user access system uniformly assigns IP addresses to the front-end distribution equipment, user access gateway and support equipment. The specific location of the system is between the core network and the service network. It adopts the network architecture of front-end distribution equipment and distributed deployment of multiple user access gateways, which can realize the unified access to the operator's self-operated business, cooperative SP business and open Internet applications. input distribution and distributed processing. For the sake of simplicity, in this embodiment and the following embodiments, all self-operated, cooperative SPs, and open Internet data service platforms are collectively referred to as application servers (AS...
Embodiment 2
[0060] This embodiment will describe the distributed user access system in detail on the basis of the first embodiment. Such as Figure 4 As shown, the distribution device is directly connected to the core network, works in transparent mode, and is responsible for identifying all data traffic of the core network and redirecting the data packets according to the preset forwarding strategy, for example:
[0061] ■ Send WAP / HTTP protocol packets to HTTP user access gateway;
[0062] ■Forward RTSP packets and corresponding RTP media streams to the Streaming gateway;
[0063] ■Forward the data packets of the FTP / FTAM protocol to the FTP gateway;
[0064] ■Forward the Radius packet whose target IP address points to the user information registration server to the user information registration server.
[0065] Figure 5 It is a logical architecture diagram of a distribution device for a distributed user access system according to Embodiment 2 of the present invention. Such as F...
Embodiment 3
[0076] This embodiment will describe the user access gateway on the basis of the first and second embodiments. The user access gateway is a node for data service access and management control, which is transparent to users. The user access system deploys multiple user access gateways in a distributed manner in the network. One end of the gateway is connected to the distribution device, and the other end is connected to the service server or the open Internet through the IP network. Each user access gateway only processes data packets of a specific protocol or application. The types of user access gateways include but are not limited to:
[0077] HTTP gateway: perform proxy access and processing for HTTP browsing data traffic, the above processing includes: content adaptation, protocol optimization, content caching, inserting user information in HTTP Header, etc.;
[0078] FTP Gateway: Provide proxy access and processing for FTP applications of FTP and FTAM protocols;
[007...
