摘要
设备到设备(D2D)通信是长期演进(LTE-A)系统使用的一种基于接近度的技术。当D2D通信中启用prose的UE跨单元边界移动时，期望实现无缝切换。但是，LTE-A没有规定D2D切换程序，目前的LTE-A切换程序无法支持ProSe业务连续性需求[1]。因此，需要一种高效的D2D切换机制来满足需求。本文提出了一种考虑D2D对信号质量的D2D切换机制。该机制包括基于D2D切换决策方法的联合切换过程和半切换过程。采用城市交通仿真(Simulation of Urban Mobility, SUMO)[2]进行交通模型和性能评估仿真。该机制的特性满足了ProSe服务连续性要求，同时降低了D2D HO故障率，并减少了源eNB和目标eNB之间交换的信息量。
Handover mechanism for device-to-device communication
Device-to-Device (D2D) communication is a proximity-based technique used by Long Term Evolution-Advanced (LTE-A) systems. When a ProSe-enabled UE in D2D communication moves across a cell boundary, seamless handover is expected. However, LTE-A does not specify D2D handover procedures, and the current LTE-A handover procedures cannot support the ProSe service continuity requirements [1]. Therefore, an efficient D2D handover mechanism is necessary to meet the requirements. In this paper, a D2D handover mechanism, which considers the signal quality of D2D pairs, is proposed. The proposed mechanism includes a Joint Handover procedure and a Half Handover procedure based on a D2D handover decision method. Simulation of Urban Mobility (SUMO) [2] is adopted for the mobility model and performance evaluation simulations. The properties of this mechanism satisfy the ProSe service continuity requirements while decreasing the D2D HO failure rate as well as reducing the amount of information exchanged between the source eNB and the target eNB.
