The present invention provides an indoor terminal positioning method, device, and network system, wherein the method includes: obtaining first downlink signal information and first indoor location information corresponding to an IoT terminal installed at a fixed indoor location; according to the first The downlink signal information and the first indoor location information generate indoor anchor point training samples; use machine learning algorithms to train the indoor anchor point training samples to obtain an indoor positioning model; obtain the second downlink signal information corresponding to the mobile terminal located indoors , using the indoor positioning model to process the second downlink signal information to obtain second indoor location information corresponding to the mobile terminal. The indoor terminal positioning method, device and network system of the present invention solve the problem of difficult positioning of 4G mobile terminals indoors, can improve the positioning accuracy of 4G mobile terminals located indoors, and improve user experience.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to an indoor terminal positioning method, device and network system. Background technique [0002] Narrow Band Internet of Things (NB-IoT) has become an important branch of the Internet of Everything. NB-IoT is built on a cellular network and only consumes about 180KHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network to reduce deployment costs and achieve smooth upgrades. The NB-IoT network and the LTE 4G network have similar wireless propagation models and follow the same 3GPP technical protocol. China Telecom started the construction of NB-IoT for the entire network in 2017. The NB-IoT network has the characteristics of strong coverage, low power consumption, and multiple connections. It will be built in a large number of indoor scenarios such as remote meter reading and smart parking. The current network operation data platf...
