Consolidated Security Mode Messages Reduce Communication Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication systems face increased overhead and delayed communication between base stations and user equipment due to complex transmission and reception procedures of control messages, which need to be simplified.
Innovation Solution
A method and apparatus that simplify the transmission and reception of security configuration and capability information between a base station and user equipment by using a single procedure, including the transmission of a security mode command message and a security mode complete message, which request and include ciphering and integrity protection algorithms, and optionally include capability information for multiple radio access technologies, allowing for bearer establishment with reduced communication delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate procedures are used for transmitting security configuration information and capability information, then each type of information can be transmitted reliably, but the overhead increases and communication delay occurs
Solution Approach 1:
The patent combines the transmission of security configuration information and capability information into a single integrated message exchange procedure. The base station transmits both security configuration and capability request in one message, and the UE responds with both security confirmation and capability information in one reply message, eliminating the need for separate procedures and reducing communication delay
2Loss of information
If multiple separate message procedures are used for control message transmission, then complete information exchange is achieved, but the overhead increases
Solution Approach 1:
The patent merges multiple control message functions into consolidated message structures. The security mode command message includes both security configuration information and capability information request, while the security mode complete message contains both security confirmation and capability information response, reducing the number of separate messages and procedures required
Solution Approach 2:
The control message structure is designed to serve multiple functions simultaneously. The security mode command message not only configures security parameters but also requests capability information, making it a multi-functional message that reduces overall procedure complexity

AI summary
An operation method of a UE in a communication system includes receiving, from a base station, a security mode command message including information requesting reporting of capability information and security configuration information; identifying the security configuration information included in the security mode command message; and transmitting, to the base station, a security mode complete message including the capability information requested by the security mode command message.
