    • Wireless communication systems wherein services involving two or more stations in the system may be activated automatically. Data is communicated between airborne stations according to a TDMA protocol, where the data is transmitted in time slots organized in frames of a repeating frame structure. A link address is associated with at least one time slot. The stations select link addresses for transmission of data according to a self-organizing transmission algorithm. Each station broadcasts data messages of a first type at a first repetition rate and receives such corresponding messages from the other stations. At least based on the received data messages of the first type, each station determines whether a service activation criterion is fulfilled with respect to at least one other station. If the service activation criterion is fulfilled, the station starts to transmit data messages of a second type, which pertain to a service that involves the station itself and the at least one other station.
    • 可以自动激活涉及系统中两个或多个站的业务的无线通信系统。 根据TDMA协议,在机载站之间传送数据,其中数据以组织在重复帧结构的帧中的时隙发送。 链接地址与至少一个时隙相关联。 站点根据自组织传输算法选择数据传输的链路地址。 每个站以第一重复率广播第一类型的数据消息,并从其他站接收这样的相应消息。 至少基于所接收到的第一类型的数据消息,每个站确定是否满足至少一个其他站的服务激活标准。 如果满足服务激活标准,则站开始发送第二类型的数据消息,这涉及涉及站本身的服务和至少一个其他站。

    • The invention relates to wireless communication systems wherein services involving two or more stations in the system may be activated automatically. Data is communicated between airborne stations (A, B) according to a TDMA protocol, where the data is transmitted in time slots organized in frames of a repeating frame structure. A link address is associated with at least one time slot, and the stations select link addresses for transmission of data according to a self-organizing transmission algorithm. Each station (A, B) broadcasts data messages of a first type (D1) at a first repetition rate and receives such corresponding messages from the other stations (A, B). At least based on the received data messages of the first type (D1), each station determines whether a service activation criterion is fulfilled with respect to at least one other station (A, B), for example by the other station being located within a limit distance (rA). If the service activation criterion is fulfilled, the station (A, B) starts to transmit data messages of a second type (D2), which pertain to a service that involves the station itself and the at least one other station (A, B).
    • 本发明涉及无线通信系统,其中系统中涉及两个或多个站的业务可以被自动激活。 根据TDMA协议在空中站(A,B)之间传送数据,其中数据以重复帧结构的帧组织的时隙发送。 链路地址与至少一个时隙相关联,并且站点根据自组织传输算法选择用于传输数据的链路地址。 每个站(A,B)以第一重复率广播第一类型的数据消息(D SUB 1),并从其他站(A,B)接收这样的相应消息。 至少基于接收到的第一类型的数据消息(D 1> 1),每个站确定是否满足关于至少一个其他站(A,B)的服务激活标准 由另一站位于限制距离(r A A)之内。 如果满足服务激活标准,则站(A,B)开始发送第二类型的数据消息(D< 2>),其涉及涉及站本身的服务,并且至少 另一站(A,B)。
