Title: CELL IDENTITY-BASED POSITIONING METHOD AND POSITIONING SERVER, AND MOBILE DEVICE
Abstract:
The present disclosure relates to a cell identity-based positioning method, comprising: receiving a positioning request message transmitted by a mobile device; transmitting an adjacent cell measuring instruction to the mobile device; receiving an adjacent cell measurement report submitted by the mobile device, the adjacent cell measurement report comprising a cell global identity of a trans-station adjacent cell satisfying a preset threshold criterion; acquiring coordinate information of a corresponding adjacent cell on the basis of the cell global identity of the trans-station adjacent cell in the adjacent cell measurement report; determining positioning point coordinates on the basis of coordinate information of a serving cell and the coordinate information of the trans-station adjacent cell acquired; and transmitting the positioning point coordinates to the mobile device. The positioning point coordinates acquired per the positioning method are of increased accuracy. The present disclosure also relates to a positioning server and the mobile device.
