Terminal Access Method for Passive and Semi-Passive Tags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing network access procedure for passive or semi-passive electronic tags in 3GPP networks is complex, leading to increased network access delays and failing to meet the differentiated requirements of passive and semi-passive electronic tags regarding delay, identification efficiency, and information security.
Innovation Solution
A terminal access method that identifies the type of terminal based on received messages and triggers either the sending of identification information to an application server or an authentication procedure, depending on the terminal type, to simplify and optimize network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a unified complex network access procedure is used for all electronic tags, then information security is maintained through authentication, but network access delay increases and inventory efficiency decreases
Solution Approach 1:
The patent segments the electronic tag population into different types (passive and semi-passive) and applies different access procedures to each type. Passive electronic tags use a simplified access procedure without authentication, while semi-passive electronic tags use a complete authentication procedure, thereby resolving the contradiction between security and access speed.
Solution Approach 2:
The patent applies different quality levels of access procedures to different electronic tag types. The simplified procedure is applied locally to passive tags where security requirements are lower, while the rigorous authentication procedure is applied locally to semi-passive tags where security is more critical, optimizing overall system performance.
2Loss of time
If a simplified network access procedure is used for electronic tags, then network access delay is reduced and inventory efficiency improves, but information security cannot be ensured
Solution Approach 1:
The patent divides the access procedure into two segments: a simplified segment for passive electronic tags that prioritizes speed, and a secure authentication segment for semi-passive electronic tags that prioritizes security. This segmentation allows each type to receive the appropriate level of access control.
Solution Approach 2:
The patent changes the authentication parameter (whether to perform authentication) based on the electronic tag type. For passive tags, the authentication parameter is set to false, enabling fast access. For semi-passive tags, the authentication parameter is set to true, ensuring security. This parameter-based differentiation resolves the contradiction.
3Ease of manufacture
If a unified network access procedure is used for all electronic tags, then implementation is simple, but differentiated requirements of passive and semi-passive tags cannot be satisfied
Solution Approach 1:
The patent segments the access procedure into type-specific paths based on electronic tag classification. The network access management function determines the tag type and routes it to the appropriate procedure (simplified or authenticated), thereby satisfying differentiated requirements while maintaining clear implementation boundaries.
Solution Approach 2:
The patent introduces dynamic adaptability by making the access procedure flexible based on the electronic tag type. The system dynamically selects between simplified and authenticated procedures, allowing it to adapt to different tag types and their specific requirements, thus improving versatility without overly complicating implementation.
