Signaling Transmission Method, Data Transmission Method, and Communication Apparatus

Smart overview of the Invention

The patent application introduces a signaling transmission method and a data transmission method, aimed at enhancing communication networks by decoupling security functions from communication functions. This separation allows for independent evolution and flexible deployment of security features, aligning with the future trends in communication network security technology. The method involves a trustworthiness protocol and protocol stack, which includes both a control plane and a service plane, to manage and transmit trustworthiness signaling and data.

Technical Context

In existing mobile networks, communication protocols are closely tied with security functions, requiring significant modifications across multiple nodes such as terminals, access network devices, and core network devices to upgrade security features. This integrated approach results in a heavy workload and complex operations. The proposed method addresses these challenges by offering a decoupled approach, enabling easier updates and enhancements to security functions without affecting communication protocols.

Methodology

The signaling transmission method is applied to a communication apparatus, which may include various protocol layers for data packet processing, transmission, connection establishment, and channel setup. A first protocol layer, or trustworthiness control plane protocol layer, is responsible for generating and transmitting trustworthiness signaling for functions like trustworthiness management, policy negotiation, and service requests. This layer operates at a higher level in the protocol stack, facilitating the independent evolution of security functions.

Security and Flexibility

The application supports the deployment of an independent security protocol that can be standardized and hot-swapped, offering more diverse security technologies. This approach allows communication protocols to focus on their primary functions, thereby improving efficiency. The trustworthiness protocol supports various services such as authentication, authorization, and blockchain services, providing advanced security support for future communication networks.

Implementation and Applications

In practice, trustworthiness signaling can be exchanged between different communication apparatuses, such as terminals and network nodes, enhancing security through a dedicated protocol layer. The management of trustworthiness functions includes various operations like activation, configuration, and updates, offering flexible and diverse management capabilities. The trustworthiness information encompasses requirements, capabilities, and policies, supporting comprehensive subscription and management of security-related data across the network.
