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。
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.
