Description

数据发送方法、数据发送终端以及基站 技术领域
本发明涉及通信领域,具体而言,涉及数据发送方法、数据发送终端以及基站。
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***容量和覆盖提出了较高要求。另一方面社交网络、近距离数据共享、本地广告等应用的流行使得人们对了解附近感兴趣的人或事物并与之通信(Proximity Services,邻近服务)的需求逐渐增加。传统的基于小区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。
D2D技术可以工作在授权频段或非授权频段,允许多个支持D2D功能的用户设备(即D2D用户设备,D2D User Equipment,D2D UE在有网络基础设施或无网络基础设施的情况下进行直接发现/直接通信。D2D技术通常包括D2D发现技术和D2D通信技术。D2D发现技术是指用于判断/确定两个或多个D2D用户设备之间相互邻近(例如在可进行D2D直接通信范围之内)或用于判断/确定第一用户设备邻近第二用户设备的技术。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。
图1是根据相关技术中的数据交互的示意图,如图1所示,R12和R13的D2D应用场景主要有三种:
1)UE1和UE2在蜂窝网络的覆盖下进行数据交互,用户面数据不经过网络基础设施,如图1的模式1;
2)在弱/无覆盖区域的UE中继传输,如图1中的模式2,允许信号质量较差的UE4通过附近有网络覆盖的UE3与网络进行通信,能帮助运营商扩展覆盖、提高容量;
3)在发生地震或紧急情况,蜂窝网络不能正常工作的情况下,允许设备间直接通信,如图1中的模式3,UE5,UE6和UE7间控制面和用户面都不经过网络基础设施而进行一跳或多跳的数据通信。
在以上R13D2D场景2)和3)中,D2D UE可以作为中继节点,使得蜂窝网络覆盖边缘或覆盖外的remote D2D UE能通过中继节点UE与网络进行蜂窝通信,且使得D2D UE间通过中继节点UE进行D2D通信。R13 D2D中,作为中继节点的D2D UE(也称为relay UE)在层3(即IP层)根据目标IP地址/端口号等信息进行数据的转发,而在R14 D2D技术中,考虑可穿戴式设备(例如,MTE或NB-IoT设备)通过relay UE接入网络场景,为了使得运营商(即核心网网元MME等,以及基站)能更有效的管理可穿戴式设备(即remote UE),要求relay UE在层2进行数据的路由转发,并且需考虑remote UE与relay UE之间采用non-3GPP接入技术(例如,WIFI或蓝牙),但现有技术并未提供remote UE通过非3GPP接入技术与relay UE连接且采用层2数据路由转发方式下的承载配置和映射方法,从而导致层2中继功能无法正确执行。
因此,针对相关技术中remote UE通过非3GPP接入技术与relay UE连接时remote UE或relay UE无法正常发送数据的问题,尚未提出解决方案。
