Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication methods lack secure and effective solutions for convergence scenarios involving different communication systems, particularly in scenarios where wireless short-range communication and 5G cellular networks converge.
Innovation Solution
A communication method involving nodes that release a connection using a preconfigured key and establish a new connection with an updated key, enabling secure authentication and key updates to enhance security in converged communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a preconfigured key is used for communication authentication in converged scenarios, then communication can be established between different communication systems, but communication security is compromised due to key reuse across systems
Solution Approach 1:
The patent segments the authentication key into system-specific components. Each communication system (e.g., 5G, Wi-Fi) uses its own dedicated key material, preventing key reuse across systems. The authentication process is divided into system-specific authentication steps, ensuring that compromise in one system does not affect others.
Solution Approach 2:
The patent applies local quality by making authentication keys system-specific rather than universal. Each communication system has its own key derivation function and key material tailored to its security requirements, allowing optimized security for each system while maintaining overall convergence capability.
2Duration of action of stationary object
If communication connections are maintained across different systems, then service continuity is improved, but system overhead increases due to managing multiple authentication contexts
Solution Approach 1:
The patent performs preliminary authentication actions during initial connection establishment in each system. Authentication credentials and security contexts are pre-configured and cached during system-specific setup phases, allowing faster subsequent authentication and reducing real-time overhead when switching between systems.
Solution Approach 2:
The patent creates a universal authentication framework that handles multiple communication systems through a common interface. The authentication management entity can manage credentials for different systems (5G, Wi-Fi, etc.) using unified procedures, reducing the complexity of managing separate authentication mechanisms for each system.

AI summary
This application discloses a communication method, apparatus, and system, and relates to the field of communication technologies. The method includes: obtaining a second key used for communication authentication with a second node, where the second key is different from a preconfigured first key; receiving, from the second node, a release request for a first communication connection, where the first key is used for communication authentication on the first communication connection; and sending a connection establishment request to the second node, where the connection establishment request is used to request to establish a connection based on the second key. The method provides a technical solution in which the first node and the second node release a connection after determining an updated key, and establish a connection by using the new key, to implement an authentication procedure in a multi-communication scenario convergence scenario.
