摘要： Disclosed is a system and method for performing a fast channel scan so as to minimize the communication disruption period (10) which occurs during a handoff of a mobile station (STA) (20-23) in a wireless local area network (WLAN) (100). Each mobile station (STA) includes an associated nearest-neighbor table identifying nearest-neighbor APs (14-16) in the network to the AP with which the STA is currently associated. When a STA (20-23) performs a handoff, its nearest-neighbor table is used to perform a prioritized search of those channels of operation included in the table belonging to nearest-neighbor APs (14-16). In this manner, by prioritizing the search to first search the channels of operation belonging to nearest-neighbor APs (14-16), there is a greater likelihood of locating a candidate ap (14-16) to form an association with in less time as compared with the prior art search method of blindly searching each and every operating channel in the network.

摘要： Under the present invention, a method and system for improved handoff of a mobile device between wireless subnetworks is provided. Specifically, under the present invention, a mobile device will directly associate with a new access point of a new wireless subnetwork (layer 2 handoff) before associating with a agent of the new subnetwork (layer 3 handoff). Once the association with the new access point is complete, a forwarding request will be sent from the new access point to the old access point of the wireless subnetwork wit which the mobile device was previously associated. The forwarding request causes all data packets intended for the mobile device that are received by the old access point to be forwarded to the new access point. Then, once the mobile device has the completed its association with the agent of the new wireless subnetwork, the mobile device will receive data packets directly through the new subnetwork.

摘要： An apparatus and method are provided for power management in an Independent Basic Service Set (IBSS) Wireless Local Area Network (WLAN) based on adjusting ATIM window size dynamically. In the present invention, each STA uses the gap between the last overheard Ad-hoc traffic indication message ATIM frame transmission and the end of the ATIM window to determine whether to increase or decrease the size of its ATIM window. Each STA of an IBSS competes to send its Beacon containing the size of its ATIM window and the window size of the winner is adopted by all STAs of the IBSS.

摘要： Under the present invention, a wireless component such as an access point or a mobile device is configured to manage the buffering of newly transmitted TCP packets. Specifically, the wireless component can receive both forwarded TCP packets and newly transmitted TCP packets. If a set of newly transmitted TCP packets is received out of order (i.e., before a set of previously transmitted TCP packets that must be forwarded), one out of order (newly transmitted) TCP packet will be passed for each of a quantity of tokens present on the wireless component. Each out of order TCP packet that is not passed will be buffered. Once a previously requested forwarded TCP packet is received and passed, the quantity of tokens is restored to a predetermined quantity, and a commensurate number of buffered TCP packets can be passed.

摘要： A method for fast active scanning and an Access Point apparatus that reduces the delay in convention active scanning. The method includes the step of giving an AP higher priority to transmit a probe response than is currently known. This priority comes at the delay of transmission of the probe response, so preferably the probe response can be delayed by just the time that the AP needs to prepare the response plus the time, if any, for the frame already in the air to finish. According to the invention, a method can include steps for: sending a uni-cast probe request message by an (STA) 238, 248, 268 on a particular channel having at least one Access Point (AP) 258, 278 in communication therewith; receiving by one particular (AP) 278 the probe request message sent by the (STA); sensing by the particular (AP) 278 of a point coordination function (PCF) interframe space (PIFS) 325 of the particular channel; and sending by the particular (AP) 278 of a probe response message to the (STA) 238 in response to the probe request message after the PIFS. As the probe request is uni-cast, there is no need for a backoff interval as only one AP will respond. Since normal traffic utilizes the longer DIFS space plus backoffs to avoid collisions, the AP will always be able to respond to a probe request of scan faster than other items can respond on the channel, thus giving the AP priority when sending the probe response message.
摘要翻译：用于快速主动扫描的方法和减少常规主动扫描中的延迟的接入点装置。该方法包括给予比当前已知的AP更高的优先级来发送探测响应的步骤。这个优先级是在传输探测响应的延迟时间，所以优选地，探测响应可以延迟到AP需要准备响应的时间加上已经在空中的帧完成的时间（如果有的话）。根据本发明，一种方法可以包括以下步骤：由（STA）238,248,268在具有与其通信的至少一个接入点（AP）258,278的特定信道上发送单播探测请求消息; 由一个特定（AP）278接收（STA）发送的探测请求消息; 由具体（AP）278感测特定信道的点协调功能（PCF）帧间间隔（PIFS）325; 以及响应于PIFS之后的探测请求消息，特定（AP）278将探测响应消息发送到（STA）238。由于探测请求是单播的，因为只有一个AP将响应，所以不需要退避间隔。由于正常流量利用较长的DIFS空间加上回退来避免冲突，因此AP始终能够以比其他项目能够在该通道上作出响应更快的速度响应探测请求，从而在发送探测响应消息时赋予AP优先级。

摘要： A plurality of methods, apparatus and computer program for providing warning to a station (STA) associated with an Access Point (AP) in a WLAN that a disassociation the AP is imminent. The steps include (a) selecting a station (STA) for disassociation from a particular Access Point (AP) of a WLAN; (b) by updating a newly created reason code field of a 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.
