Description

数据传输方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种数据传输方法及装置。
背景技术
无线通信网络目前没有达到随时随地都保证连通性。原因是目前已商用的无线通信技术只能在大多数的场景下提供相对好的连通性，但是在弱覆盖、极端干扰或者网络资源过载的区域不能满足用户的需要。
未来的第五代通信(5G)网络将有相当的需求在物联网、车载网络，远程信息处理以及自动化领域，这些领域当前没有应用是由于目前的无线通信网络的可靠性保证不够。图1是根据相关技术的基于网络功能的5G网络结构示意图。超可靠机器通讯(Ultra-reliable/Critical MTC，简称为U-MTC)是5G网络一个重要的目标，它和现有的使用者为人的通讯需求有很大的不同，核心需求是超可靠，超低时延，对数据吞吐量的要求不高。
目前的第二/三/四代通信(2/3/4G)网络总的架构特点是用一种网络架构形态满足了所有的业务需求，并且网络的设计目标主要是解决人的无线通讯需求。5G网络的目标在4G网络解决人的无线宽带通讯需求基础上还要解决物的无线通讯需求，这样导致不同场景的技术指标变化巨大，一种网络架构形态不能适应所有的业务需求，针对不同场景要求有不同的网络架构形态。而与此同时网络功能虚拟化(Network Function Virtualization，简称为NFV)技术和软件定义网络(Software Defined Network，简称为SDN)技术快速发展；最终导致了重构的5G架构，5G网络的几个关键特征如下：
1、网络整体是云化的；2、网络可以灵活切片(支持面向用例场景的网络优化和网络隔离)；3、网络功能和服务需求通过编排部署形成(针对不同场景要求有不同的网络架构形态)；4、网络的部署粒度从逻辑实体级别细化为功能组件级别。
目前一些致力于研究5G的组织如Metis在一些公开的文档中提出了5G的架构。5G的架构有如下特点：聚焦于网络功能而不是网络实体/节点，网络功能组件化，基于用例来进行功能组件的组织，接口定义为功能组件的接口而不是网络实体的接口。5G的功能大体分为几个部分：可靠服务组合(Reliable Service Composition，简称为RSC)，中心管理实体(Central Management Entities，简称为CME)，无线节点管理(Radio Node Management，简称为RNM)，空中接口(Location of Air Interface，简称为AI)。以上大的功能细分为多个小的功能组件，并且各个小的功能组件根据需要可部署在不同的位置(逻辑实体)。
经研究发现，由于5G的业务形态和场景是多样化的，为了满足各种需求，需要有多种类型的小区存在，从网络制式上来讲，会存在2G、3G、4G、5G小区以及无线保真网接入点(Wifi AP)等，从覆盖范围上来讲，会存在宏小区，微小区，超密集网络(Ultra-Dense Network，简 称为UDN)，因此会存在多种无线接入技术(Radio Access Technology，简称为RAT)融合的问题。5G网络中，U-MTC等业务要求无线通讯必须超可靠，超低时延，但对数据吞吐量的要求不高，然而，在目前的无线通信网络中还无法保证这种超可靠通信(Ultra-Reliable Communication，简称为URC)。
针对相关技术中无法实现数据的URC传输的问题，目前没有提出有效的解决方案。
