Radio Station Handover Control Using Flight Path Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drone communication systems face challenges in maintaining continuous communication due to gaps between estimation and actual situations, leading to potential control issues and safety concerns.
Innovation Solution
Implementing a system where radio stations and core network nodes proactively manage handovers based on flight path information, initiating handover processes without explicit requests, ensuring seamless communication transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handover control is performed based on estimation, then flight path adjustment is achieved, but communication continuity cannot be guaranteed when estimation deviates from actual situation
Solution Approach 1:
The patent applies preliminary action by having the first radio station proactively transmit the handover acceptance message before the actual handover occurs. The control section in the first radio station determines in advance that handover should be performed based on flight path information, and the communication processing section transmits the acceptance message proactively to the second radio station, ensuring the handover is ready when needed without waiting for a request message.
2Device complexity
If traditional request-response handover protocol is used, then protocol simplicity is maintained, but handover response time increases and communication continuity is compromised
Solution Approach 1:
The first radio station performs preliminary action by determining in advance that handover should be performed based on flight path information, and proactively transmitting the handover acceptance message before the actual handover occurs. This eliminates the need for the second radio station to send a request message, significantly reducing handover response time and ensuring communication continuity.
3Reliability
If proactive handover management is implemented, then communication continuity is improved, but system complexity increases due to additional control mechanisms
Solution Approach 1:
The first radio station performs self-service by autonomously determining when handover should occur based on flight path information and proactively transmitting the acceptance message without requiring requests from other nodes. This self-service approach improves communication continuity while the complexity is contained within a single radio station's control section.

AI summary
In order to further facilitate continuous communication with a flying mobile terminal, a first radio station according to an example aspect of the present disclosure includes a control section configured to, in a handover of a mobile terminal configured to move according to flight path information, control the handover according to the flight path information from a second radio station to the first radio station; and a communication processing section configured to transmit a message including information related to acceptance of the handover to the second radio station without receiving a request message for the handover transmitted from the second radio station.
