面向6G的低轨卫星通信系统移动性管理技术
Mobility Management Technologies for 6G-Oriented Low Earth Orbit Satellite Communication Systems
摘要
Abstract
The LEO satellite system,with its unique advantages such as global coverage and low latency,combined with the direct satellite-to-ground communication method,has shown great potential in enhancing global communication capabilities and will become an important part of next-generation communication network.However,the system faces many challenges in mobility management,in-cluding frequent satellite handovers,complex signaling interactions,and allocation and management of handover resources.To better advance the development of mobility management in LEO satellite communication systems,this paper first provided an overview of re-cent progress in mobility management related to architecture design,handover mechanisms,and traffic continuity management.It then presented mobility management enhancement technologies for 6G LEO satellite systems.Finally,this paper discussed the opportunities and challenges that future LEO satellite communication systems may face in mobility management.关键词
