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).
