D2D通信中Chief UE应用的研究

Research on application of Chief UE in D2D communication

Chief UE的作用是辅助实现D2D通信与蜂窝网络通信更好地无缝切换并且提高通信的质量。对Chief UE的概念进行了详细描述,并且对于其在切换中的作用进行了相应的阐述和论证:在传统D2D通信的基础上,定义了其中一个性质稳定良好的UE为Chief UE,进行D2D连接的内部管理和通信,并且在需要切换时,能够进行通行保持直到整个通信切换的完成和结束。将具有Chief UE的D2D切换同不具有Chief UE的D2D切换进行了相应的对比和论述,以更好地论证Chief UE存在的必要性。

Chief UE is used to aid better seamless handover between D2D communication and cellular network communica-tion,and to improve the communication quality. The concept of Chief UE is described in detail,and the role in the switch is elaborated and demonstrated. Based on traditional D2D communication,one UE with steady performance is chosen and defined as Chief UE to conduct D2D connection inner management and communication. The communication can be kept till the handoff is over when deeded. The D2D switch with Chief UE and without Chief UE are compared and discussed,to demonstrate the ne-cessity of the existing of UE.
