Abstract

The invention provides a key processing method, device and equipment in a fail soft scene and a storage medium, and the method comprises the steps: receiving an RRC connection establishment completion message sent by UE in the fail soft scene; and then, according to an encryption and integrity protection key generated by the ASU MME according to the stored basic key of the UE, an initial security activation process is carried out, and an initial context is established for the UE. Wireless capability information of the UE is then obtained and a security mode command is sent to the UE. And finally, receiving a security mode completion message returned by the UE, and completing the attachment of the UE. In the method, the base station receives the RRC connection establishment completion message carrying the NAS message sent by the UE, thereby realizing the attachment to the UE, reducing the risk of being counterfeited in the initialization security activation process, and improving the security.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a key processing method, apparatus, device and storage medium in a fault weakening scenario. Background technique [0002] The fault weakening scenario means that in the Long Term Evolution (LTE) Broadband Trunking Communication (BTrunC) system network, when the communication between the base station and the core network is interrupted, or the core network fails, the base station can Handles the registration and service requests of users within the coverage area of ​​the base station, and supports scenarios such as single call and group call. [0003] In the prior art, the implementation of the fault mitigation scenario mainly involves establishing a connection between a base station and a user equipment (User Equipment, UE) and performing initial security activation, and then performing cluster registration on the user. [0004] However, in the prior art...
