The embodiment of the invention discloses an Internet of Things terminal equipment network access method and system and a storage medium. The method belongs to the technical field of Internet of Things, and comprises the following steps: if a terminal initiates a registration request to a core network in a non-LADN area, accessing the core network according to a common DNN carried in the registration request; if the terminal moves to the LADN area, TA information corresponding to the LADN area is obtained from a base station, and the TA information is sent to the core network, so that the core network is triggered to start a TA updating function to obtain TA target information; the core network corrects the common DNN according to the TA target information to obtain an LADN DNN; and the terminal reconstructs a PDU session flow with the core network by using the LADN DNN so as to access the core network. According to the embodiment of the invention, the whole network access process does not need a URSP functio
