Data Plane Identity for Secure Terminal Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack a clear method for data transmission between a user terminal and the network using a data plane protocol, which hinders efficient data communication and security.
Innovation Solution
A data transmission method that involves obtaining a data plane identity (DPID) by a terminal or network-side device to establish a connection and transmit data, ensuring the terminal's identity is not leaked, thereby enhancing security and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If control plane (CP) and user plane (UP) protocols are used for terminal communication, then communication control is achieved, but data transmission efficiency and security are insufficient
Solution Approach 1:
The patent introduces a data plane (DP) as an intermediary layer between the control plane and user plane. The DP protocol acts as a mediator that handles data transmission specifically, separating control functions from data transmission functions. This allows efficient data transmission through the dedicated DP while maintaining security through protocol-level protections, resolving the contradiction between transmission efficiency and security.
2Productivity
If a data plane protocol is introduced for data transmission, then data transmission capability is enhanced, but the method for terminal identification and connection establishment is undefined
Solution Approach 1:
The patent segments the communication protocol into three distinct planes: control plane (CP) for control signaling, user plane (UP) for traditional data transmission, and data plane (DP) for enhanced data transmission with built-in identification mechanisms. By segmenting the protocol architecture, the patent defines clear procedures for terminal identification using DP-specific identifiers and connection establishment, reducing overall system complexity while enhancing data transmission capability.
3Ease of operation
If terminal identity is transmitted for data plane connection, then connection establishment is enabled, but identity leakage risk increases
Solution Approach 1:
The patent uses data plane identifiers (DP identifiers) as copies or representations of terminal identities rather than transmitting actual terminal identities. The DP identifier serves as a pseudonymous copy that enables connection establishment and data transmission without revealing the true terminal identity. This copying mechanism allows easy connection establishment while preventing identity leakage, as the copied identifier can be used for communication purposes without exposing sensitive identity information.
Data Source
AI summary
A data transmission method includes obtaining, by a terminal, a DPID corresponding to the terminal, the DPID being used to identify the terminal on a data plane; establishing, by the terminal, a connection to the data plane using the DPID; and sending by the terminal, data to the data plane using the DPID.
