Abstract
A device receives sensor data for a group of user equipment (UE) that are located within or on a structure. The device determines, based on a set of measured barometric pressures identified by the sensor data, a set of relative altitudes that identify altitudes of the group of UEs relative to one or more known geographic locations. The device determines, based on at least a portion of the sensor data and relative altitude data that identifies the set of relative altitudes, and for each UE of the group of UEs, a floor on which the UE is located. The device causes, based on determining respective floors on which the UEs of the group of UEs are located, a data structure to store a mapping of each UE to the respective floors. The device performs one or more actions based on the mapping.
