Claim 0:
1. A control method for a terminal device in a non-terrestrial cellular data communication network, the network comprising one or more airborne or spaceborne base stations moving along a flight trajectory, for connecting the terminal device to said network, the method comprising the following steps:
providing flight trajectory data for said one or more airborne or spaceborne base stations in a memory element of said terminal device;
providing terminal location data in the memory element of said terminal device;
using a data processing unit, determining at least one time slot during which a wireless communication channel between said terminal device and at least one of said one or more airborne or spaceborne base stations is estimated to be available, based on said flight trajectory data and on said terminal location data; and
using the data processing unit, scheduling a data reception or transmission between said terminal device and said at least one of said one or more airborne or spaceborne base stations during the determined time slot,
wherein providing terminal location data comprises the additional step of estimating the terminal location data based on detected properties of at least three signals received at the terminal device from at least three different positions taken by the one or more airborne or spaceborne base stations.
