Abstract:
Embodiments of the present invention provide a floor positioning method and system, and a device, and relate to the communications field. The method includes: receiving a reference signal sent by at least one access point in an indoor environment in which the UE is located; determining measurement information based on a polarization direction of the at least one received reference signal, where the measurement information includes at least one access point identifier and a proportion-related value of a vertical polarization direction relative to the polarization direction of the reference signal corresponding to the at least one access point identifier; sending the measurement information to a positioning server; and receiving location information of the UE sent by the positioning server, where the location information of the UE includes a floor location of the UE, and the floor location of the UE is determined based on the measurement information. The present invention is to resolve a problem in a related technology that floor information of UE is estimated incorrectly, thereby accurately obtaining a floor location of the UE.
