Abrégé
(EN)
A plurality of methods, apparatus and computer program for providing a warning to a station (STA) associated with an Access Point (AP) in a WLAN indicating that a disassociation the AP is imminent. The steps of one of the methods include (a) selecting a station (STA) for disassociation from a particular Access Point (AP) of a WLAN; (b) updating a reason code field of a message(i.e. a measurement request frame or a site report response message) to indicate to the selected STA that it has become a candidate for disassociation; and (c) transmitting the message to the selected STA. Upon receipt by the STA of a message indicating that the selected STA has become a candidate for disassociation, the selected station scans other Access Points from a list to find another Access Point to associate with before being cut off by the current Access Point,and being finally handed off from the current to another (selected) Access Point.

(ZH)

用于在WLAN中给与接入点(AP)相关联的站提供指示去关联AP是即将来临的警告的多种方法、设备和计算机程序。这些方法之一的步骤包括:(a)选择用于从WLAN的特定接入点(AP)中去关联的站(STA);(b)更新消息(即,测量请求帧或站点报告响应消息)的原因代码字段,以便向选择的STA指示:它已变为去关联的候选者;和(c)给选择的站发送该消息。一旦由STA接收到指示选择的STA已变成为去关联候选者的消息,选择的站扫描列表中的其他接入点,以查找在被当前接入点断开之前与之相关联的另一接入点,并且最终从当前接入点切换到另一(选择的)接入点。
