摘要： AP's associated with a communication network and any wireless devices desiring contact, operated according to a protocol in which each wireless device selects AP's with which to communicate. A system coordinator causes the AP's to operate so as to guide each wireless device to an AP selected by the system coordinator. This has the effect that, notwithstanding that the protocol involves having the wireless device make the selection of AP, functionally, the AP's make the selection for it. In a 1st technique, multiple AP's share an identifier, with the system coordinator directing one particular AP to respond to the wireless device, thus appearing to wireless devices as a “personal cell”. In a 2nd technique, AP's each maintain identifiers substantially unique to each wireless device, with the system coordinator directing only one particular AP to maintain any particular wireless device's identifier, thus appearing to wireless devices as a “personal AP”.

摘要： A system and method for providing a seamless transition between access points for mobile devices. The method comprises associating a unique identifier for a plurality of mobile stations with a unique identifier for a first network in an acknowledgment table, then, upon receiving a frame from a mobile station, acknowledging the reception of the frame if the frame includes the unique identifier for the mobile station and the unique identifier for the network. The transfer of operation between access points is effectuated through the use of control circuitry which transfers portions of the contents of the acknowledgement table between various access points. This has the effect that the mobile stations does not sense a change in access points and thus the roaming from a first access point to a second access point is seamless.
摘要翻译：一种用于在移动设备的接入点之间提供无缝转换的系统和方法。该方法包括将多个移动站的唯一标识符与确认表中的第一网络的唯一标识符相关联，然后在从移动站接收到帧时确认帧的接收，如果帧包括唯一标识符为移动台和网络的唯一标识符。通过使用控制电路来实现接入点之间的操作的传送，该控制电路在各个接入点之间传送确认表的内容的部分。这具有这样的效果：移动台不会感测到接入点的变化，因此从第一接入点到第二接入点的漫游是无缝的。

摘要： Using the feature named “KEY_SEARCH_AD1” in the Atheros 11n chipset, an access point can determine whether to send an ACK packet in response to a message packet in response to whether the BSSID present in the sender address is present in the keycache. The AP can maintain a list of about 128 arbitrarily selected BSSID's, to each of which it will respond with an ACK packet if it receives a message from a mobile station with that BSSID. (1) the number of mobile stations that can be assigned to that AP is relatively greater. (2) the selection of those BSSID's is no longer constrained by having to match the AP's BSSID using a mask. With selection of those BSSID's being no longer so constrained, it is easier to assign BSSID's to mobile stations while allowing those mobile stations to roam among multiple AP's.
摘要翻译：在Atheros 11n芯片组中使用名为“KEY_SEARCH_AD1”的功能，响应于发送方地址中存在的BSSID是否存在于密钥缓存中，接入点可以确定是否响应于消息分组发送ACK分组。 AP可以维护约128个任意选择的BSSID的列表，如果从具有该BSSID的移动站接收到消息，则每个BSSID将用ACK分组来响应。（1）可以分配给该AP的移动站的数量相对较多。（2）通过必须使用掩码匹配AP的BSSID，这些BSSID的选择不再受到限制。通过选择这些BSSID不再受到限制，将BSSID分配给移动台更容易，同时允许这些移动台在多个AP之间漫游。

摘要： A control element identifies the possibility that a station will transfer to a destination AP, and prepares that destination for a handoff. The control element repurposes messages from the station which indicate a possible near-term handoff, to prepare access points to receive that handoff. The control element treats a neighbor list request as a trigger to select which AP's to identify, to restrict the neighbor list to selected AP's, and to prepare each selected AP for a handoff. In selecting a destination AP, the control element also selects a particular set of related features for the combination of that AP and BSS. When an AP receives a repurposed message, it informs the control element, which selects destination AP's for transfer. The control element treats the repurposed message like a probe request. The control element prepares more than one AP for transfer if handoff is possible to more than one AP.
