  • Patent number: 10805820
    Abstract: A radio network node (12) in a wireless communication network (10) configures a wireless device (30) to send a measurement report responsive a determination by the device (30) that its current network coverage condition matches a predefined coverage condition that is characteristic of airborne operation of the device (30) at the current location of the device (30). As advantageously recognized herein, the network coverage condition experienced by the wireless device (30) at its current location changes as it rises above ground level. By configuring die device (30) to send a measurement report when its network coverage condition satisfies a coverage condition that, for the current location of the device (30), is characteristic of airborne operation, the network (10) effectively defines a mechanism for detecting airborne operation of the device and making one or more control decisions for the device (30), e.g., to limit network interference experienced or caused by the device (30).
