Embodiment

[0070] Embodiment: Assume that there are four types of equipment supported by the terminal: 5G, BLUETOOTH, WIFI, and 2G. The terminal accesses the 5G base station through the 5G standard, and the fusion positioning device is located on the 5G base station. The devices of the three reference device types of WIFI perform measurements and report them to the 5G base station, and the 5G base station completes the fusion positioning of the terminal. Therefore, TypeNum is equal to 3, and this embodiment also assumes that ThresholdNum is equal to 2 (the measurement volume is divided into three intervals) , and the threshold values ​​of the three reference device types are the same, that is, Type i_0 Value -65dbm, Type i_1 The value is -85dbm (i=0, 1, 2), assuming that the number of required measurement intervals K is equal to 2, the number of reference devices N required for positioning operations is 6, and the reliability of the reference device types in descending order is: 5G, For...

Abstract

The invention provides a fusion positioning method and device, and relates to the field of indoor and outdoor positioning. The method comprises the steps of: 1, enabling a scheduling terminal to measure the measurement quantity of each device under a specified type of reference device; 2, dividing all measurement quantities under a single reference equipment type into different intervals accordingto the reference equipment type and an interval threshold thereof; 3, determining an energy-saving and bandwidth-reducing measurement strategy of the round; 4, enabling the scheduling terminal to perform measurement reporting based on the new measurement strategy; and 5, updating the interval reference equipment member according to the reporting result, if the change rate of the updated intervalreference equipment member is greater than the proportion threshold 1, skipping to the step 1, and otherwise, skipping to the step 5. By adopting the scheme provided by the invention, the number of the reference equipment to be measured, the measurement frequency of the reference equipment and the measurement quantity report information amount are effectively reduced, the terminal power consumption and the measurement quantity report bandwidth overhead in the fusion positioning process are further optimized, and the practical application value of the fusion positioning scheme is finally improved.

Description
