POSITIONING METHOD POSITIONING SERVER AND POSITIONING SYSTEM

摘要

Mii+1 MjMProvided in embodiments of the present invention are a positioning method positioning server and positioning system. The present invention can eliminate positioning error introduced by TAE improve positioning accuracy and realize accurate positioning for a plurality of mobile terminals at the same time. The positioning method comprises: acquiring by a positioning server respective position coordinates of positioning nodes; acquiring by the positioning server a reference signal time difference(RSTD) between an th positioning node and an th positioning node in the positioning nodes and a th mobile terminal in two mobile terminals; determining by the positioning server a relative RSTD according to the RTSD; determining by the positioning server according to the relative RTSD and the position coordinates of the positioning nodes the position coordinates of the two mobile terminals. The present invention is applicable to the technical field of wireless communications.
