Claim 3:
4. The method for type state estimation according to claim 3, wherein:
an updated type state estimate of said state of said user equipment not being a drone is equal to a preceding type state estimate probability multiplied with a likelihood of said obtained kinematic state estimate updates and normalized, in which 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 not being a drone; or
said updating recursively of said type state estimate is performed according to:

P(¬D|zt)∝P(I({circumflex over (x)},f)|¬D)P(¬D|zt-1),

where P(¬D|zt) is said probability for said user equipment to not be a drone conditioned on a present kinematic state estimate update, P(¬D|zt-1) is said probability for said user equipment to not be a drone conditioned on a preceding kinematic state estimate update and P(I({circumflex over (x)}, f)|¬D) is said likelihood of said obtained kinematic state estimate update, I({circumflex over (x)}, f) is said smooth indicator function, {circumflex over (x)} is said kinematic state estimate and f is the feature for which the likelihood is evaluated, and where t is time.
