    • The present invention provides a communication system for performing the seamless handover of a mobile station between at least a first wireless access point and a second wireless access point within wireless LAN. The mobile station is in the coverage of at least the first wireless access point for receiving and/or sending the data from and/or to the first wireless access point. The system comprises a first server for storing data from a data source; a switch for exchanging the data between the first server and the first and second wireless access points; and a second server coupled to the switch, for receiving the data from the first server via a switch when the mobile station roams from one access point to another one, and transferring the stored data to the mobile station through the switch after the roaming.
    • 本发明提供了一种用于在无线LAN内的至少第一无线接入点和第二无线接入点之间执行移动台的无缝切换的通信系统。 移动台至少在第一无线接入点的覆盖范围内,用于从第一无线接入点接收和/或发送数据。 该系统包括用于存储来自数据源的数据的第一服务器; 用于在第一服务器与第一和第二无线接入点之间交换数据的交换机; 以及耦合到所述交换机的第二服务器,用于当所述移动站从一个接入点漫游到另一个接入点时经由交换机从所述第一服务器接收所述数据,并且在所述漫游之后通过所述交换机将所存储的数据传送到所述移动站。
