METHOD, DEVICES, SYSTEM AND COMPUTER PROGRAM PRODUCT FOR INCREASING THE POSITIONING ACCURACY OF A MOBILE USER EQUIPMENT BY USING DATA OF A GLOBAL NAVIGATION SATELLITE SYSTEM

摘要

The invention relates to a method to increase the positioning accuracy of a mobile user equipment entity being connected to a mobile communication network by using data of a global navigation satellite system, wherein the mobile communication network comprises a plurality of base station entities and a plurality of reference stations, and wherein the global navigation satellite system comprises a plurality of satellites, wherein the method comprises the following steps: - in a first step, a specific reference station of the plurality of reference stations receives - from multiple satellites of the plurality of satellites of the global navigation satellite system - at least a first satellite radio signal, the specific reference station being associated to a specific base station entity of the plurality of base station entities of the mobile communication network, - in a second step, subsequent to the first step, the specific reference station or a server entity of the mobile communication network calculates correction information based on the first satellite radio signal received by the specific reference station, wherein the correction information comprises a first set of correction information indicating a first geographical correction and at least a second set of correction information indicating a second geographical correction, wherein the first geographical correction differs from the second geographical correction, -- in a third step, subsequent to the second step, the correction information is transmitted, by the specific base station entity of the plurality of base station entities, to the mobile user equipment entity, - in a fourth step, the mobile user equipment entity receives - from multiple satellites of the plurality of satellites of the global navigation satellite system - a second satellite radio signal, - in a fifth step, subsequent to the third step, the position of the mobile user equipment entity is determined based on the second satellite radio signal and, depending on the location of the mobile user equipment entity, at least one of the first geographical correction and the second geographical correction.
