Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0053] image 3 is a flowchart of a pre-authentication method for cross-subnet handover according to an embodiment of the present invention. In this embodiment, the pre-authentication method for inter-subnet handover starts at step 110 .

[0054] In step 110, the current access point receives the pre-authentication request information from the communication terminal, and transmits the received pre-authentication request information to the second virtual terminal through the UDP channel through the first virtual terminal, wherein the first virtual terminal is located at the current access point....

Abstract

The invention discloses a method for pre-authentication and pre-configuration, and a system thereof. The system for pre-authentication and pre-configuration comprises a current access point and a candidate access point located in different subnets, and also comprises a first virtual terminal located in the current access point and a second virtual terminal located in the candidate access point, the first virtual terminal and the second virtual terminal communicating through an User Datagram Protocol (UDP) channel. The system also comprises a candidate access point which belongs to a different domain with the current access point, a third virtual terminal located in the candidate access point, a first virtual server in a same domain with the current access point and a third virtual server in the same domain with the candidate access point, the first virtual terminal, the first virtual server, the third virtual terminal and the third virtual server communicate with each other through the UDP channel. Through using virtual terminals and / or virtual server to send information related to the pre-authentication and the pre-configuration in the UDP layer, the method enables switches among different subnets in the same domain, and even among different domains.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a pre-authentication and pre-configuration method and system thereof. Background technique [0002] When a communication terminal safely switches from one access point to another in the 802.11 network, it must exchange authentication information and configuration information with another access point, and then successfully connect after authentication and configuration. Among them, the authentication process based on 802.1X and the configuration process based on Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) are the two main factors causing the handover delay. figure 1 is a schematic diagram of an 802.11 authentication system based on 802.1X in the prior art. Such as figure 1 As shown, an EAP (EAP Over LAN, EAPOL) architecture in a local area network generally includes an authenticator (that is, an access point) and an authentication, authori...
