The invention provides an indoor terminal positioning method, an indoor terminal positioning device and a network system. The method comprises the following steps: acquiring first downlink signal information and first indoor position information corresponding to an IoT (Internet of Things) terminal installed at an indoor fixed position; generating an indoor anchor point training sample according to the first downlink signal information and the first indoor position information; training the indoor anchor point training sample by adopting a machine learning algorithm to obtain an indoor positioning model; and obtaining second downlink signal information corresponding to the indoor mobile terminal, and processing the second downlink signal information by using the indoor positioning model toobtain second indoor position information corresponding to the mobile terminal. According to the indoor terminal positioning method and device and the network system, the problem that the 4G mobile terminal and the like are difficult to position indoors is solved, the positioning accuracy of the indoor 4G mobile terminal and the like can be improved, and the use experience of a user is improved.
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...
