Description

实现业务连续性的通信方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种实现业务连续性的通信方法及装置。
背景技术
随着无线多媒体业务的发展，人们对高数据速率和用户体验的需求日益增长，从而对传统蜂窝网络的系统容量和覆盖提出了较高要求。另一方面公共安全、社交网络、近距离数据共享、本地广告等应用场景使得人们对了解附近人或事物并与之通信(Proximity Services，邻近服务)的需求逐渐增加。传统的以基站为中心的蜂窝网络在高数据速率以及邻近服务的支持方面存在明显的局限性，在这种需求背景下，代表未来通信技术发展新方向的D2D(Device-to-Device，设备到设备)技术应运而生。D2D技术的应用，可以减轻蜂窝网络的负担、减少用户设备的电池功耗、提高数据速率，并改善网络基础设施的鲁棒性，很好地满足上述高数据速率业务和邻近服务的要求。目前D2D技术又称之为邻近服务(Proximity Services，简称为ProSe)，单边链路(Sidelink，简称为SL)。
D2D技术通常包括D2D发现技术和D2D通信技术，其中，D2D发现技术是指用于判断/确定第一用户设备是否邻近第二用户设备的技术。通常，D2D用户设备间可通过发送或接收发现信号/信息来发现对方；D2D通信技术是指D2D用户设备之间部分或全部通信数据可以不通过网络基础设施而直接进行通信的技术。
另一方面，随着万物互联需求的发展，第三代合作伙伴计划(3rd Generation Partnership Project，简称为3GPP)对机器类型通信(Machine Type communication，简称为MTC)进行了标准化，R12和R13的演进的 MTC(Evolved MTC，简称为eMTC)工作基本已经完成，窄带物联网(Narrow Band-Internet of Things，简称为NB-IoT)的标准化工作目前尚在进行。其中R13eMTC在支持低成本的基础上，增加了覆盖增强的支持以及带宽受限的支持。一般来说，eMTC用户设备(User Equipment，简称为UE)的收发射频能力限制在1.4MHz，而NB-IoT设备的射频收发带宽限制在180kHz。演进的基站(Evolved Node B，简称为eNB)和eMTC/NB-IoT UE之间通常通过数据传输的多次重复达到覆盖增强的目的。考虑到eMTC/NB-IoT设备低成本特性，通常希望尽可能延长eMTC/NB-IoT设备的使用寿命，而覆盖增强特定会导致数据包的多次重复传输，从而快速耗费掉UE的电量。除了eMTC以及NB-IoT设备，可穿戴式设备也具备类似的应用需求，如低成本，带宽受限，低功率消耗等。
在3GPP新立项的课题中包括增强的D2D，主要针对可穿戴设备(Wearables)和物联网(Internet Of Thing，简称为IOT)/机器类型通信(Machine Type Communication，简称为MTC)应用，本文中上述设备统称为远程用户设备；可穿戴设备通过UE和接入网之间的中继(UE-to-network relay)实现与网络的通信，其中Wearables UE在eNB覆盖内可以通过PC5或Uu口通信，至少上行数据采用PC5。图1是根据本发明实施例的采用UE-to-network relay的通信架构示意图，采用UE-to-network relay通信架构如图1所示。
在相关技术中，对于上述提到的各种远程用户设备，由于其通信链路的状态可能随设备移动或者网络负载变化发生变化，并导致通信操作失败，然而对于远程用户设备通信链路的确定方式(例如初始选择或者重选时的通信链路确定方式)，目前并没有给出合适的处理方案。
针对相关技术中缺少远程用户设备通信链路的确定方式和业务连续性的问题，目前尚未给出相应的技术方案。
