5G Terminal Handover Search for Low-Power IoT Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in mobile communication systems is the discontinuation of communication with IoT devices having ultra-low power consumption, such as battery-less devices, due to their movement, which is not addressed by existing technologies.
Innovation Solution
A communication system is implemented with a base station supporting a 5G radio access system, where multiple communication terminals search for and reconnect with IoT devices when a connection is lost, ensuring continuous communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If IoT devices use ultra-low power consumption mode, then energy efficiency is improved, but connection stability deteriorates due to device movement
Solution Approach 1:
The patent merges multiple communication terminals into a collaborative search system. When one terminal loses connection with an IoT device, multiple terminals jointly perform search operations to locate and reestablish connection, transforming individual terminal limitations into collective capability that maintains connection stability while preserving low power consumption mode
Solution Approach 2:
The patent implements preliminary actions by having communication terminals perform proactive search operations before complete disconnection occurs. The base station coordinates search requests and multiple terminals prepare to take over communication duties in advance, preventing total connection loss and enabling seamless transition without requiring high power consumption for continuous monitoring
2Reliability
If multiple communication terminals perform search processing, then connection recovery capability is improved, but system complexity increases
Solution Approach 1:
The base station serves as an intermediary that coordinates the multi-terminal search process. It receives search requests from terminals, manages search resource allocation, and directs terminals to appropriate search targets. This central coordination simplifies the overall system architecture by providing a single point of control rather than requiring complex peer-to-peer coordination between terminals
Solution Approach 2:
The patent segments the search function across multiple terminals rather than concentrating it in a single terminal or the base station. Each terminal performs search operations for specific IoT devices within its coverage area, dividing the overall connection recovery task into manageable segments that reduce individual terminal complexity while maintaining system-wide reliability

AI summary
A communication system includes a base station configured to support a fifth generation radio access system, communication terminals configured to be connected to the base station, and a device configured to be connected to the base station in which, in a case where a connection between the device and the communication terminal is in a disconnected state, a plurality of the communication terminals perform processing to search for the device, and a communication terminal that has been successful in searching for the device operates as a communication terminal being a connection target of the device.
