具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本申请进行进一步详细说明。应当理解,此处所描述的具体实施例仅用以解释本申请,并不用于限定本申请。
需要说明的是,虽然在装置示意图中进行了功能模块划分,在流程图中示出了逻辑顺序,但是在某些情况下,可以以不同于装置中的模块划分,或流程图中的顺序执行所示出或描述的步骤。说明书、权利要求书或上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。
在相关技术中,终端设备在与网络进行传输数据之前,必须通过初始接入过程连接到网络。因此,需要先通过信令建立通信通道后,才可以实现终端设备和外界数据的传输。由于信令传递导致的开销非常高,因此对于小数据传输而言,传输信令的次数可能会大于传输数据包的次数并且传输信令的字节数可能会大于本身数据包的字节数,从而导致传输效率较低。而且,对于海量终端通信的场景,信令的开销问题会被进一步放大。所以,现有移动数据通信系统信令和用户数据分离的机制不适合小数据包的传输。
具体地,初始接入过程包括小区搜索、系统消息接收和随机接入等阶段。小区搜索是终端设备利用小区主同步信号PSS和辅同步信号SSS进行下行时间和频谱同步,以及获得物理小区标识的过程。通过小区搜索完成同步后,终端设备接收并解码系统消息,获取后续进行随机接入必需的系统消息。在获取系统消息后,终端设备通过随机接入完成上行同步,从非RRC连接态如RRC_IDLE态或RRC_INACTIVE态,进入RRC连接态,为上行和下行数据传输做好准备。
从上述通信管道建立流程可知,移动通信系统的通信流程是先通过信令建立通信通道后,才可以实现终端设备和外界数据的传输。示例性地,以终端设备下行数据通道为例,业务发起后,信令交互流程如下:首先通过寻呼过程帮助网络寻呼正处于非RRC连接态的终端设备,若终端设备处于RRC空闲态,核心网会发送NAS寻呼终端设备。其次,终端设备收到核心网 的寻呼后,终端设备的NAS层触发服务请求。同时,终端设备高层触发MAC层发起随机接入请求并通过物理层发送随机接入请求,通过RRC连接建立请求、RRC连接建立、RRC连接建立完成的流程,使核心网建立起用户面和控制面的连接以及安全机制。自此,建立起核心网到终端设备的下行和上行通道,终端设备才可以进行数据包的发送和接收。
基于上述情况,本申请实施例提供了一种数据传输方法及其设备、存储介质、程序产品,具体如下:在初始接入过程中的小区搜索阶段之后,网络设备获取同步块消息,并将同步块消息发送至终端设备,接着,终端设备会根据同步块消息读取数据包。根据本申请实施例的技术方案,本申请实施例通过把数据包的传输时机提前到小区搜索阶段之后,使终端设备与网络设备在小区同步后立即进行数据的传输,以减少初始接入过程后续阶段中因数据传输引起的终端设备与网络设备之间的信令开销,降低终端设备的能耗以及接收数据时延。
下面结合附图,对本申请实施例作进一步阐述。
如图1所示,图1是本申请一个实施例提供的用于执行数据传输方法的实施环境的示意图。
在图1的示例中,该实施环境设置有终端设备100和网络设备200,其中,终端设备100和网络设备200之间通信连接。
其中,终端设备100和网络设备200中均设置有处理器和存储器,其中,处理器和存储器可以通过总线或者其他方式连接。
存储器作为一种非暂态计算机可读存储介质,可用于存储非暂态软件程序以及非暂态性计算机可执行程序。此外,存储器可以包括高速随机存取存储器,还可以包括非暂态存储器,例如至少一个磁盘存储器件、闪存器件、或其他非暂态固态存储器件。在一些实施方式中,存储器可选包括相对于处理器远程设置的存储器,这些远程存储器可以通过网络连接至该实施环境。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
本领域技术人员可以理解的是,该实施环境可以应用于3G通信网络系统、LTE通信网络系统、5G通信网络系统、6G通信网络系统以及后续演进的移动通信网络系统等,本实施例对此并不作具体限定。
本领域技术人员可以理解的是,图1中示出的实施环境并不构成对本申请实施例的限定,可以包括比图示更多或更少的部件,或者组合某些部件,或者不同的部件布置。
在图1所示的实施环境中,终端设备100或者网络设备200中的处理器可以调用储存在存储器中的数据传输程序,从而执行数据传输方法。
基于上述实施环境,下面提出本申请的终端设备侧的数据传输方法的各个实施例。
如图2所示,图2是本申请一个实施例提供的终端设备侧的数据传输方法的流程图,该方法应用于终端设备,包括但不限于步骤S100和步骤S200。
步骤S100、获取由网络设备发送的同步块消息;
步骤S200、根据同步块消息读取数据包。
具体地,本申请实施例在初始接入过程中的小区搜索阶段之后,网络设备获取同步块消息,并将同步块消息发送至终端设备,接着,终端设备会根据同步块消息读取数据包。根据本申请实施例的技术方案,本申请实施例通过把数据包的传输时机提前到小区搜索阶段之后,使终端设备与网络设备在小区同步后立即进行数据的传输,以减少初始接入过程后续阶段中因数据传输引起的终端设备与网络设备之间的信令开销,降低终端设备的能耗以及接收数据 时延。
需要说明的是,传统新无线(NR,New Radio)同步块(SSB,Synchronization Signal Block)包括主同步信号(PSS,Primary Synchronization Signal)、辅同步信号(SSS、Secondary Synchronization Signal)和物理广播信道(PBCH,Physical Broadcast CHannel),不论是RRC_INACTIVE或RRC_IDLE态的用户设备都需要定期接收同步块消息。
基于上述同步块消息的消息结构,本申请实施例可以通过将数据包、或者数据包的调度授权信息、或者数据包的调度授权信息的配置信息复用在物理广播信道内;本申请实施例还可以通过设计特殊结构的同步块消息,使得同步块消息不仅包括有主同步信号、辅同步信号和广播消息,还包括有数据包或者数据包的调度授权信息。上述多种方式均可以使终端设备与网络设备在小区同步后立即进行数据传输,因此可以最大程度节省建立RRC连接的信令开销,降低终端设备的能耗以及终端设备的接收数据时延。具体地,上述多种方式的实施例可以参照图3至图12所示,具体如下:
