摘要： In a wireless communication channel, the time per a service interval is distributed among multiple data services. The data services have been allocated airt ime quotas in order to comply with their QoS requirements. These airtime quotas are scaled by a factor that is the ratio between, on the one hand, the time available per service interval for accommodating data of these services and, on the other hand, the total of the airtime quotas. This allows the services to use more airtime in case not the entire service interval has been allocated.
摘要翻译：在无线通信信道中，每个服务间隔的时间间隔分布在多个数据业务中。为满足其QoS要求，数据业务已经分配了空中配额。这些通话时间的配额是以一个因素来衡量的，一方面是每个服务间隔可用的时间之间的比例，用于容纳这些服务的数据，另一方面是总时间。这样，如果没有分配整个服务间隔，服务可以使用更多的通话时间。

摘要： Techniques for dynamically switching between synchronous and asynchronous operation modes in body area networks (BANs). One embodiment includes a method (400) for transitioning from an asynchronous mode to a synchronous mode in a medium access control (MAC) of a BAN. A device receiving a switch mode command (S410) performs the acts comprising: setting a timer to a time period specified in the switch mode command (S430); propagating the received switch mode command to other devices in the BAN (S440); upon expiration of the time period, tuning to a channel selected from a set of channels reserved for the synchronous mode (S460); and initializing a device to operate as either a master device or a slave device in the synchronous mode of operation (S470). Another embodiment includes a method (300) for transitioning from a synchronous mode to an asynchronous mode in a MAC of a body area networks (BAN).
