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

Embodiment 1

[0044] Example 1: Roaming in different areas in the same operator / enterprise

[0045] The main problem for the same carrier / enterprise is the mesh connection problem, also known as N 2 problem, therefore, other networking methods, including but not limited to hierarchical networks and star networks, can be used to solve this problem.

[0046] In one embodiment of the present invention, the layered network is shown in Figure 2 (a), the underlying AAA servers are not interconnected, and the entire network connection is configured between the high-level AAA servers to form a mesh network or a semi-mesh network , thus greatly reducing the maintenance workload, generally by an order of magnitude.

[0047] Among them, the typical configuration between high-level AAA servers is, for example:

[0048] [User data section]

[0049] Username = lisi@local.com

[0050] attribute = common user

[0051] Next authentication master server =

[0052] Next Authentication Standby Server = ...

Embodiment 2

[0116] Example 2: Roaming between two different operators / enterprises

[0117] Set up an AAA gateway on the boundary of each operator / enterprise. When a user roams between two operators / enterprises, all authentication and billing roaming between each other go through this gateway. All AAA servers, in addition to configuring local user authentication and accounting information, configure the domain names of all roaming users as the default path or roaming path to the AAA gateway. The specific configuration process is the same as that for the layered or star network above. Each AAA server in the network does not need to configure a path corresponding to each roaming domain name. In this way, when performing maintenance between two networks, every time a new domain name is added, deleted, or modified, only the corresponding path modification needs to be performed on the AAA gateway, and the AAA server in the network does not need to be modified, thereby reducing the The mainten...

Embodiment 3

[0142] Embodiment 3: Roaming among multiple operators

[0143] When a specific user roams, it can only be roaming between two operator entities, but when a user connected to a certain access device roams, roaming among multiple operators will occur. Judging the roaming between multiple operators is actually the sum of judging the roaming situation of a certain user.

[0144] When each operator or enterprise communicates with each other, a bilateral agreement is negotiated. Therefore, when an operator or enterprise wants to communicate with multiple operators or enterprises, it must negotiate bilateral agreements multiple times, and there are differences between the agreements. Very inconvenient and technically difficult.

[0145] By forming a roaming alliance, all roaming data configurations are performed in the alliance, so that all operators and enterprises connected to the roaming alliance can roam with each other. And when an operator or enterprise wants to communicate w...

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...
