Abstract

The wireless communication technology of the present invention discloses a positioning method and device for a mobile terminal. In this solution, when determining the distance, firstly, the association between the stored terminal model ID, cell ID and AOA value and the associated unit TA distance is carried out. In the relationship, determine the unit TA distance associated with the terminal model ID, cell ID and AOA value, that is, the unit TA distance is related to the terminal model ID, the cell ID of the cell where it is located, and the AOA value in the cell Therefore, calculating the geographic location information of the terminal according to the determined unit TA distance can improve the positioning accuracy, avoiding the defect of low accuracy in the prior art.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a positioning method and device for a mobile terminal. Background technique [0002] At present, with the development of mobile communication technology and the growth of service requirements, there are more and more positioning services based on the location of mobile terminals. Location-based services involve many fields such as transportation, logistics, public security, emergency and daily life, and can provide navigation, logistics management, traffic information, schedule and many other services, so they are widely used. [0003] In the prior art, there are mainly the following positioning methods: CELL ID (Identity, logo) positioning method, OTDOA (Observe Time Difference of Arrival, observable time difference of arrival) positioning method, A-GPS (Assisted Global Positioning System, Assisted Global Positioning System) positioning method, and TA (Timing Advance...
