Method for pre-authentication and pre-configuration, and system thereof

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. 本发明公开了一种预认证和预配置方法及其系统。用于预认证和预配置的系统包括位于不同子网的当前接入点和候选接入点，还包括位于当前接入点的第一虚拟终端和位于候选接入点的第二虚拟终端；第一虚拟终端和第二虚拟终端间通过UDP通道进行通信。该系统还包括与当前接入点属于不同网域的候选接入点，以及位于候选接入点的第三虚拟终端、与当前接入点同一网域的第一虚拟服务器以及与候选接入点同一网域的第三虚拟服务器；第一虚拟终端、第一虚拟服务器、第三虚拟终端和第三虚拟服务器间通过UDP通道进行通信。本发明通过使用虚拟终端和/或虚拟服务器在UDP层发送与预认证和预配置相关的信息，能够快速在同一网域的不同子网间甚至不同网域间进行切换。
