摘要： The present invention, in the case where one terminal station attempts to transmit an asynchronous packet to other terminal station, has an object to provide a communication control method that enables the source terminal station to perform communications, even when the destination terminal station is in a sleep mode, without the necessity of any special processing.
In order to accomplish the above object, the present invention has that: a station ID of a destination terminal station is included in a polling request message from a terminal station to a control station; the control station having received the polling request message confirms the operation state of the destination terminal station indicated by the station ID; the control station makes a sleep release request to the destination terminal station when it is confirmed that the destination terminal station is in a sleep mode; and the control station performs polling to the source terminal station having made the polling request after it is confirmed that the destination terminal station shifts to an active mode.摘要翻译： 本发明在一个终端机尝试将异步分组发送到其他终端站的情况下，具有提供通信控制方法的目的，即使当目的地终端站处于 睡眠模式，无需任何特殊处理。 为了实现上述目的，本发明的目的终端站的站ID被包括在从终端站到控制站的轮询请求消息中; 已经接收到轮询请求消息的控制站确认由站ID指示的目的地终端站的操作状态; 当确定目的地终端站处于睡眠模式时，控制站向目的地终端站发出睡眠释放请求; 并且在确认目的地终端站转移到活动模式之后，控制站对已经做出轮询请求的源终端进行轮询。
