Abstract
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.
