Abstract

The information transmission method, device, device, and storage medium provided in this embodiment, the method includes: receiving a redirection message from a network device for switching from a 5G network to a 4G network, and the redirection message includes a frequency point of at least one 4G cell If it is determined that it is impossible to reside in at least one 4G cell according to the frequency point information of at least one 4G cell, it will reside in the TA cell in the original tracking area and trigger the NAS process of the non-access layer. The NAS process is used to send the target to the network device. message, the target message is used to instruct the user equipment to camp on the original TA cell. The NAS process is used to notify the network device that the user equipment resides in the original TA cell, so as to realize the information synchronization between the network device and the UE.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless communication, and in particular, to an information transmission method, device, device, and storage medium. Background technique [0002] With the development of the mobile Internet and the growing demand of users for mobile data, the fifth generation of mobile communication technology (5th generation Mobile networks, referred to as 5G), the performance goals of 5G are high data rate, reduced delay, energy saving, cost reduction, increased system capacity and large-scale device connection. [0003] At this stage, when user equipment (UE) successfully registers on the 5G network and activates data services, the network equipment initiates a redirection process from the 5G network to the 4G network due to reasons such as 5G signals. If there is no suitable 4G cell and the camping fails, it will re-camp on the original tracking area (Tracking Area, TA) cell. [0004] However...
