SECURITY HANDLING FOR RRC RESUME FROM INACTIVE STATE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18530043 titled 'SECURITY HANDLING FOR RRC RESUME FROM INACTIVE STATE

Simplified Explanation

The communication system described in the abstract involves a host computer that sends user data to a cellular network for transmission to a user equipment (UE) via a base station. The base station processes the data, including verifying security tokens and managing security contexts, before transmitting the user data to a host application.

• The host computer forwards user data to a cellular network for transmission to a UE.
• The base station processes the data, including verifying security tokens and managing security contexts.
• The base station transmits the user data to a host application.

Original Abstract Submitted

A communication system including a host computer is provided herein. The host computer may include processing circuitry configured to provide user data and a communication interface configured to forward the user data to a cellular network for transmission to a user equipment (UE). The cellular network comprises a base station having a radio interface and base station processing circuitry. The base station processing circuitry configured to store a previously active security context for the UE, receive from the UE an RRCResumeRequest message including a security token, generate a temporary security context for the UE, use the temporary security context to verify the security token, send an RRC message to the UE, if no response to the RRC message is received from the UE, discard the temporary security context and retrieve the previously active security context. Thereafter, the base station transmits the user data for a host application.
