摘要： A population estimation server 10 according to an embodiment includes a signal acquisition unit 11 that acquires a location registration signal periodically transmitted from a mobile terminal 20 carried by a user, and an estimation unit 12 that aggregates the acquired location registration signals for each area and for each estimation-unit-period and estimates a population for each area and for each estimation-unit-period based on an aggregation result. When an absent period in which the signal from the mobile terminal 20 staying in a target area is not acquired occurs after the location registration signal from the mobile terminal 20 is acquired, the estimation unit 12 interpolates a pseudo signal associated with the mobile terminal 20 in the absent period, and aggregates signals while excluding a location registration signal first transmitted from the mobile terminal after the absent period from an aggregation target.

摘要： A specifying unit 51 of a flying body operation management device 50 specifies an airspace in which a propagation delay equal to or greater than a threshold value occurs in the uplink of a time-division duplex between a wireless communication terminal 30 and a wireless base station 41 to which wireless communication terminal 30 is wirelessly connected. Next, an assigning unit 52 of flying body operation management device 50 performs a process of assigning, with respect to each airspace, a flying body 10 having a wireless communication terminal 20. At this time, with respect to an airspace specified by specifying unit 51, assigning unit 52 limits the assigning of flying body 10 on which wireless communication terminal 20 is mounted.
