Core Network Operator Identification Codes for Passive IoT Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack a method for operators to manage passive internet of things (IoT) terminals, as they rely on external excitation from card readers/writers and do not provide a solution for centralized management by operators.
Innovation Solution
A communication method and apparatus that enables a core network device to allocate and manage operator identification codes to IoT terminals, allowing operators to manage and authenticate these devices effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passive IoT terminals rely on external excitation from card readers/writers, then the terminals can send information to the outside, but the terminals lack centralized management capability by operators
Solution Approach 1:
The patent introduces an operator identification code as an intermediary element that bridges the gap between passive IoT terminals and operator management systems. This code, stored in the terminal's EPC memory bank, enables operators to identify and manage terminals without requiring complex external excitation infrastructure, thus improving ease of operation while maintaining relatively simple device structure
Solution Approach 2:
The operator identification code serves multiple functions: it acts as a unique terminal identifier, an authentication credential for operator management, and a key for securing terminal-network communication. This multi-functionality consolidates what would otherwise require separate systems into a single unified management approach
2Reliability
If operator identification code is stored in the terminal, then centralized management is enabled, but the terminal requires additional storage and processing capabilities
Solution Approach 1:
The patent utilizes the existing EPC (Electronic Product Code) memory bank in passive IoT terminals to store the operator identification code. Instead of requiring dedicated new storage hardware, the solution copies the management identifier into an already-present memory structure, thereby enhancing authentication security without significantly increasing terminal structural complexity
Solution Approach 2:
The EPC memory bank, originally designed for storing product identification data, is repurposed to also store the operator identification code. This multi-functional use of existing memory resources provides secure authentication capabilities while avoiding the need for additional dedicated storage components
3Ease of operation
If the core network device manages operator identification codes, then operator control is enhanced, but the network device requires additional management functions
Solution Approach 1:
The patent integrates operator identification code management into the existing core network device's EPC management functions. Rather than creating a separate management system, the operator code allocation, storage, and retrieval operations are merged with the network device's existing terminal identification management capabilities, enhancing operator control while minimizing additional functional complexity

AI summary
This application relates to the field of communication technologies, and provides a communication method and apparatus, so that an operator manages a terminal device. A core network device receives first information from a requester, where the first information indicates a first terminal; the core network device obtains an operator identification code allocated by an operator device to the first terminal; and the core network device sends second information to the first terminal, where the second information indicates the first terminal to store the operator identification code. After the operator identification code is stored in the terminal, an operator may manage the terminal based on the operator identification code.
