Method and system for providing user network roam

Abstract

A method for providing network roaming service to users and its system set roaming retransmit equipment at each operator network, the roaming retransmit equipment comprises the high layer AAA server of same operator in HCS, the central AAA server star-like network, the boarder AAA gateways of different operator, the boarder AAA gateway among multi operators and the AAA gateway of roaming union. It can configure the connection relationship at several limited equipments.

Description

field of invention [0001] The invention relates to a data communication network, in particular to a method and a system for providing users with network roaming services. Background technique [0002] Modern society has entered the information society, and communication network, as the carrier of information, has been applied to all aspects of the whole society. Commonly used communication technologies include Ethernet, Token Ring, FR (Frame Relay), IP (Internet Protocol), ATM (Asynchronous Transfer Mode), etc. Commonly used communication networks include LAN composed of Ethernet and TCP / IP. WAN and INTERNET (Internet) and so on. [0003] In the actual network, PC (personal computer) can be connected to the network in many ways, such as through LAN Switch (Ethernet switch), AP (wireless access point), VDSL (Very High Speed ​​Digital Subscriber Line), ADSL (not Symmetrical Digital Subscriber Line) and other means to access the network. [0004] In the network that needs to...

AI Technical Summary

Problems solved by technology

[0011] 1. Since all AAA servers are connected in a mesh, all AAA servers must know all other AAA servers that have connection relationships, and configuration needs to be performed on each AAA server. Therefore, the addition, deletion and change of domain names often affect the entire network. All AAA servers on the Internet require a lot of maintenance and are difficult to maintain

[0012] 2. If different operators and enterprises adopt mesh connection, they must know each other's AAA configuration, so the security is very poor

Moreover, due to management problems between operators, it is difficult to synchronize and maintenance is very difficult

[0013] 3. Due to the mesh connection between AAA servers, all authentication and billing information are distributed, and the same operator in different regions and different operators cannot be uniformly settled

Not only is there a difference between protocols, which is very inconvenient, but also technically difficult

[0015] 5. Since the access server or similar access devices also need to configure the corresponding relationship of all AAA servers, often an access device can only configure limited domain name relationships, so the scalability is poor and the maintenance is large
