Abstract

The present invention provides a network security optimization method for the Internet of Things, a user terminal, and network-side equipment. The method includes: when the RRC connection between the user terminal and the base station is established, the base station receives an IBC-based identification code from the user terminal. bearer request, and send an IBC-based bearer request carrying the user terminal identifier to the authentication unit of the core network; after the authentication unit has passed the security authentication of the user terminal, it sends an IBC-based bearer request without a security key and without wireless encryption to the base station A radio access bearer request: the base station requests the user terminal to establish a wireless data bearer without a security key and without wireless encryption based on the radio access bearer request.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to the narrowband Internet of Things, and in particular to a network security optimization method for the Internet of Things, a user terminal and a network side device. Background technique [0002] The NBIoT (Narrow Band Internet of Things) basic network platform includes a wireless access network and a core network, providing the entire Internet of Things service transmission channel. In the existing LTE network architecture, the base station (eNB) is connected to the base station through the X2 interface, and the base station is connected to the mobile control entity (MME: Mobility Management Entity) through the S1 interface, such as figure 1 shown. [0003] Narrowband Internet of Things (NBIoT) technology provides a network access method with narrow bandwidth (180kHz) and subcarrier spacing of 3.75kHz or 15kHz. It is based on the existing LTE network arch...
