Relay Apparatus Handover Destination Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing relay apparatuses for wireless communication between a wireless base station and a communication terminal lack efficient handover mechanisms, particularly in scenarios where the relay function needs to be switched on or off based on predetermined conditions, such as vehicle operation states, leading to potential communication disruptions and unmeasured handovers.
Innovation Solution
A relay apparatus with a relay function management switch and a signal transmitter that identifies a handover destination before satisfying predetermined conditions, allowing for unmeasured handovers by transmitting a signal to the communication terminal to switch to a stronger or more stable relay apparatus, without requiring measurement reports on received radio waves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the relay apparatus waits for measurement reports from the communication terminal before executing handover, then the handover decision can be made based on accurate signal quality data, but the handover process is delayed and communication disruptions occur when the relay function is switched off
Solution Approach 1:
The relay apparatus performs preliminary actions by identifying the handover destination in advance (before the predetermined condition is satisfied) and preparing handover information. When the relay function needs to be switched off, the handover can be executed immediately using pre-prepared information, eliminating the delay caused by waiting for measurement reports while maintaining accurate handover decisions
2Productivity
If the relay apparatus switches off the relay function based on predetermined conditions, then resource utilization is improved and unnecessary relay operations are avoided, but communication connectivity is disrupted
Solution Approach 1:
Before switching off the relay function based on predetermined conditions, the apparatus performs preliminary handover preparation by identifying the handover destination and notifying the communication terminal. This ensures that when the relay function is discontinued for efficiency, the communication connectivity is maintained through seamless handover to another base station
Solution Approach 2:
The apparatus provides beforehand cushioning by preparing handover information and notifying the terminal in advance before the relay function is switched off. This cushioning measure ensures that even when the relay function is discontinued, the communication connection is protected against disruption through pre-arranged handover to an alternative base station
