Abstract: A serving network node may be configured to determine an altitude position state of a terminal device. The altitude position state may be determined using information in a plurality of reports received from the terminal device, the reports comprising at least one indication of signal reception quality (201). For example, the altitude position state may be determined by comparing the at least one indication of the signal reception quality of the plurality of reports to a comparison model, or by comparing cells in the plurality of reports to information of cells in a certain area (202). Further, more reports may be requested from the terminal device for improved certainty of the determining, if needed. The determined altitude position state of the terminal device may further be transmitted, as a part of a handover process, to a handover target network node (203).

Abstract: In accordance with example embodiments of the invention there is at least a method and apparatus to perform at least detecting, by an unmanned vehicle of a communication network, a radio connection quality degradation at the unmanned vehicle; and in response to the detecting, autonomously directing the unmanned vehicle on a rescue movement path to new geographical coordinates provided by the communication network to maintain or reestablish the radio connection. Further, to perform determining that a radio connection quality degradation is to occur or has occurred at an unmanned vehicle of a communication network; and based on the determining, providing a rescue movement path to new geographical coordinates to the unmanned vehicle for a radio connection quality degradation to maintain or reestablish the radio connection.
