摘要

针对大型复杂室内场景多技术协同难、跨场景切换滞后、定位精度不稳定和服务连续性不足等问题，参考3GPP（3rd Generation Partnership Project

第三代合作伙伴计划）定位框架并进行平台级扩展，提出大语言模型辅助的室内多源定位智能调度与连续性控制方法。方法以蜂窝、Wi-Fi等测量信息为主，并可扩展适配蓝牙/UWB（Ultra Wide Band，超宽带）和惯性传感等多源数据，通过时空对齐、信号语义编码、场景识别、约束化调度和融合解算实现动态源选择。基于40万平方米商业综合体8个楼层实测数据验证，结果表明：场景识别加权准确率达到94.3%，开阔无遮挡LOS（Line-of-Sight，视距）中庭场景定位均方根误差为0.75 m，跨场景定位连续性达到88%，平均定位误差较固定权重融合方法降低49.5%。本方法可提升复杂室内场景下定位服务的连续性、稳定性和跨场景适配能力。

Abstract

To address the difficulties of multi-source positioning coordination

delayed cross-scenario handover

and insufficient service continuity in complex indoor environments such as large commercial complexes

a large language model assisted scheduling and continuity control method for indoor multi-source positioning was proposed inspired by the 3GPP positioning framework and extended at the platform level. Cellular and Wi-Fi measurements were primarily aggregated on the location service platform

with extensible adaptation to Bluetooth/UWB and inertial sensing data. Dynamic source selection was achieved through spatio-temporal alignment

signal semantic encoding

scenario recognition

constrained scheduling

and fusion calculation. The method was evaluated with field data collected from eight floors of a 400 000 m² commercial complex. The results showed that the weighted scenario recognition accuracy reached 94.3%

the root mean square error in open LOS atrium scenarios was 0.75 m

the cross-scenario positioning continuity reached 88%

and the average positioning error was reduced by 49.5% compared with the fixed-weight fusion method. The proposed method improves the continuity

stability

and cross-scenario adaptability of indoor positioning services.
