摘要： Techniques for performing IP configuration after handoff in a WLAN are described. A station associates with a first access point in the WLAN and performs IP configuration to obtain a first set of IP configuration parameters. The station thereafter exchanges data via the first access point using the first set of IP configuration parameters. The station performs handoff from the first access point to a second access point and performs IP configuration after the handoff. While the IP configuration is in progress, the station continues to exchange data via the second access point using the first set of IP configuration parameters. This avoids interruption in IP connectivity. After completing the IP configuration, the station either (i) continues to exchange data using the first set of IP configuration parameters if new parameters are not obtained or (ii) exchanges data using a second set of IP configuration parameters if obtained.
摘要翻译：描述了在WLAN中切换之后执行IP配置的技术。站与WLAN中的第一接入点相关联，并执行IP配置以获得第一组IP配置参数。该站随后通过第一组IP配置参数通过第一接入点进行数据交换。该站执行从第一接入点到第二接入点的切换，并在切换后执行IP配置。当IP配置正在进行时，站继续使用第一组IP配置参数通过第二接入点交换数据。这样可以避免IP连接中断。在完成IP配置之后，如果没有获得新的参数，则（i）继续使用第一组IP配置参数交换数据，或者（ii）如果获得，使用第二组IP配置参数交换数据。

摘要： Techniques for avoiding collision of traffic in a wireless network are described. A station detects for synchronization of its traffic with traffic of other stations. The station may detect for synchronization based on, e.g., percentage of first transmission failures, counters indicative of statistics of transmitted frames, and/or other information. The station may confirm synchronization of its traffic, e.g., by monitoring for traffic from another station during a service period for the station. The station adjusts transmission of its traffic when synchronization is detected to avoid collision with the traffic of the other stations. The station may delay transmission of its traffic by a predetermined amount of time, by a pseudo-random amount, or until after the other stations finish their transmissions.
摘要翻译：描述了避免无线网络中业务冲突的技术。站点检测其流量与其他站点的流量同步。基站可以基于例如第一传输故障的百分比，指示传输帧的统计数据的计数器和/或其他信息来检测同步。该站可以确认其业务的同步，例如通过在该站的服务周期期间监视来自另一个站的业务。当检测到同步时，该站调整其业务的传输，以避免与其他站的业务相冲突。站可以将其业务的传输延迟预定量的时间，伪随机量，或直到其他站完成其传输。
