Problems solved by technology

In this way, multiple session connections will be established for the same user, which not only causes user data to be scattered and cannot be managed centrally, but also takes up a lot of system resources
[0015] Although the 3GPP TS 33.234 specification currently proposes a solution to restrict the same user from establishing multiple sessions, the specific implementation of this solution requires the HSS to judge multiple conditions, and the process is complicated and cumbersome, and to a certain extent Increased load on HSS

Embodiment 1

[0050] This embodiment is a judging logic in an enhanced AAA server, that is, adding a judgment on whether there are multiple session connections for the same user in the AAA server, so as to ensure that only one AAA server provides services for the current user. In this embodiment, it is first judged whether to delete the new session connection, and then decides whether to authenticate the new session connection.

[0051] As shown in Figure 4, the judgment process of the AAA server in this embodiment includes the following steps:

[0052] Steps 401-404: During the access authentication interaction process of the WLAN user terminal, the AAA server that performs access authentication for the current authentication requesting user judges whether the currently requested authentication corresponds to a new session connection, and if not, continues the normal authentication Process, end the current judgment process, and return the result of success or failure to the user terminal t...

Embodiment 2

[0058] This embodiment is another judgment logic in the AAA server with enhanced functions, that is, the judgment of whether there are multiple session connections for the same user is added in the AAA server, so as to ensure that only one AAA server provides services for the current user. In this embodiment, it is decided to delete an old session connection, so the new session connection is directly authenticated.

[0059] As shown in Figure 5, the judgment process of the AAA server in this embodiment includes the following steps:

[0060] Steps 501-504: are exactly the same as the description of the first embodiment.

[0061] Steps 505-508: Judging whether the user connection exceeds the network's session connection limit for the user after the new session connection authentication is passed, if not, no special processing is performed, and the normal authentication process is continued, that is, steps 503-504 are executed; if exceeded, Then after the new session connection ...

Embodiment 3

[0063] This embodiment is based on the processing flow shown in FIG. 3, combining the interaction flow shown in FIG. 3 with the processing steps of the core idea of ​​the present invention, mainly involving changes in steps 302, 303, and 304, and other steps are basically unchanged. In this embodiment, the main modification of step 302 is:

[0064] In the process of authentication interaction, increase the AAA server's judgment on whether the current authentication corresponds to a new session connection. If it is a new session connection, it is necessary to judge whether the network's session connection limit for users is exceeded after adding a new session connection. If it exceeds, then Need to decide whether to delete a session connection or reject a new session establishment request. If a new session establishment request needs to be rejected, the rejection can be done before authentication or during the authentication process; if an old session connection needs to be del...

Abstract

The method includes following steps: a) AAA server making accessing authentication for user decides if the current authentication corresponds to new session connection; if not, ending the current processing; otherwise executing step b; b) based on network configuration rules and user sign up message, the said AAA server decides if connection exceeds the limit to current user session connection after adding current session; if not, ending the current process; if yes, determining which session connection will be deleted.

Description

technical field [0001] The invention relates to connection establishment technology in a wireless local area network (WLAN), in particular to a method for restricting WLAN users to establish multiple session connections in the WLAN. Background technique [0002] As users have higher and higher requirements on wireless access rates, a wireless local area network (WLAN, Wireless Local Area Network) emerges at the historic moment, which can provide high-speed wireless data access within a small range. Wireless local area network includes a variety of different technologies. A technical standard that is widely used at present is IEEE802.11b, which uses the 2.4GHz frequency band, and the maximum data transmission rate can reach 11Mbps. IEEE 802.11g and Bluetooth (Bluetooth) technology are also used in this frequency band. , Among them, the highest data transmission rate of 802.11g can reach 54Mbps. Other new technologies such as IEEE 802.11a and ETSI BRAN Hiperlan2 both use the ...
