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;

Abstract

The invention discloses a distributed user access system and a distributed user access method. The system is positioned between a core network and a service network and comprises flow dividing equipment, and a plurality of user access gateways arranged in a distributed manner, wherein the flow dividing equipment is connected with the core network and is used for collecting data packets transmitted by a user terminal and redirecting the data packets to the corresponding access gateways according to the protocol types and preset forwarding policies of the data packets; and the plurality of useraccess gateways are connected with the flow dividing equipment and a corresponding service server, serve as epoxy nodes to initiate service requests corresponding to the data packets to the service server, and transmit service responses fed back to a user terminal through the flow dividing equipment and the core network. In the distributed user access system and the distributed user access method, which are disclosed by the embodiment of the invention, the functional entities are distributed separately and a uniform coordinated scheduling mechanism of the functional entities is established, so the flexible arrangement of a distributed user access mode is realized and the service expansion and post management and maintenance are facilitated.

Description

technical field [0001] The invention relates to the field of core network and data service of communication technology, in particular to a distributed user access system and method. Background technique [0002] With the development of communication technology and Internet technology, the transmission bandwidth of mobile communication network continues to increase, and smart terminals are becoming the mainstream. Users can access the Internet more freely and conveniently, and various data applications are also flourishing. Mobile users are no longer satisfied with simply using traditional value-added services such as SMS, MMS, and WAP browsing. New data services such as music downloads, video calls, streaming media, EMAIL, FTP, IM, and online games are becoming the highlights of attracting users. With the continuous enrichment of services, protocols, and media types, the data service access methods of traditional mobile networks can no longer meet the needs of users. Therefo...
