Claim 5:
6. A network node for type state estimation of a user equipment connected to a wireless communication network to which said network node is connected, the network node comprising:
a processor; and
a memory comprising a computer program which, when executed by the processor, causes the network node to:
update recursively a type state estimate, being a probability for said user equipment to be a drone conditioned on obtained kinematic state estimate updates concerning said user equipment;
assign said user equipment to be a drone as a response on said type state estimate exceeding a threshold; and
wherein an updated type state estimate is equal to a preceding type state estimate probability multiplied with a likelihood of said obtained kinematic state estimate updates and normalized, and wherein said likelihood is a probability of a smooth indicator function, representing a discrimination feature of the kinematic state estimate, where said likelihood is conditioned on the user equipment being a drone.
