Description

数据传输方法及装置、存储介质、终端设备、网络设备
本申请要求2033年3月11日提交中国专利局、申请号为202210243387.8、发明名称为“数据传输方法及装置、存储介质、终端设备、网络设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种数据传输方法及装置、存储介质、终端设备、网络设备。
背景技术
在新无线(New Radio，NR)系统中，终端设备的空口有三个状态：空闲态/非激活态/连接态(RRC_IDLE/RRC_INACTIVE/RRC_CONNECTED)。空闲态终端设备与基站没有连接，只需要定期发起位置更新、小区选择重选流程和接收寻呼等；连接态终端设备与网络有连接，网络会配置无线承载以及物理层等，网络可以对终端设备进行上下行数据调度；非激活态终端设备在一定无线接入网的通知区域(RAN-based Notification Area,RNA)内移动不需要通知基站，终端设备会保留一定配置。终端设备在非连接态如果需要发起数据传输，需要进行随接入过程迁移到连接态，目前有两种随机接入流程：四步随机接入和两步随机接入。针对移动端(Mobile Terminated,MT)场景，即下行有数据需要终端设备接收，终端设备会在驻留的小区发起随机接入过程流程。
在长期演进(Long Term Evolution，LTE)系统中，引入了早期数据传输(Early Data Transmission,EDT)，允许非连接态的终端设备传输少量数据。对应的，对于有少量下行数据需要传输，可以通过增强的MT-EDT寻呼流程触发。核心网网关在收到下行数据后，会通知核心 网的移动管理节点(Mobility Management Entity,MME)待传数据量大小，MME可以将该信息通知基站用于辅助基站确定是否发起ME-EDT寻呼。如果确定发起，则在发给终端设备的寻呼消息中携带MT-EDT指示，终端设备收到该寻呼则会选择发起EDT传输。
但是，在NR场景中，由于NR系统对于小包传输引入的不同传输资源和方式，终端设备需要按照一定的规则选择不同的资源。但是在NR MT场景中，由于终端设备不知道待接收的数据业务需求，可能有些可用的配置授权小包数据传输(Configured Grant Small Data Transmission,CG-SDT)资源不能满足待传下行数据的业务需求，或者基站已配置其他终端设备使用相关配置授权资源，此时终端设备再使用CG-SDT资源会造成数据传输时延或冲突。或者基站没有发起增强寻呼，则终端设备缺少判断能否用小包数据传输的信息，导致错误使用小包数据传输响应，基站需要重新迁移终端设备到连接态而造成传输时延。

具体实施方式
本申请实施例适用的通信系统包括但不限于长期演进(long term evolution，LTE)系统、第五代(5th-generation，5G)系统、NR系统，以及未来演进系统或者多种通信融合系统。其中，5G系统可以为非独立组网(non-standalone，NSA)的5G系统或独立组网(standalone，SA)的5G系统。本申请技术方案也适用于不同的网络架构，包括但不限 于中继网络架构、双链接架构、Vehicle-to-Everything(车辆到任何物体的通信)架构等架构。
本申请主要涉及终端设备和网络设备之间的通信。其中：
本申请实施例中的网络设备也可以称为接入网设备，例如，可以为基站(base station，BS)(也可称为基站设备)，网络设备是一种部署在无线接入网(Radio Access Network，RAN)用以提供无线通信功能的装置。例如在第二代(2nd-generation，2G)网络中提供基站功能的设备包括基地无线收发站(base transceiver station,BTS)，第三代(3rd-generation，3G)网络中提供基站功能的设备包括节点B(NodeB)，在第四代(4th-generation，4G)网络中提供基站功能的设备包括演进的节点B(evolved NodeB，eNB)，在无线局域网络(wireless local area networks，WLAN)中，提供基站功能的设备为接入点(access point，AP)，NR中的提供基站功能的设备下一代基站节点(next generation node base station，gNB),以及继续演进的节点B(ng-eNB),其中gNB和终端设备之间采用NR技术进行通信，ng-eNB和终端设备之间采用演进的通用地面无线电接入(Evolved Universal Terrestrial Radio Access,E-UTRA)技术进行通信，gNB和ng-eNB均可连接到5G核心网。本申请实施例中的网络设备还包含在未来新的通信系统中提供基站功能的设备等。

如背景技术中所述，在NR场景中，由于NR系统对于小包传输引入的不同传输资源和方式，终端设备需要按照一定的规则选择不同的资源。但是在NR MT场景中，由于终端设备不知道待接收的数据业务需求，可能有些可用的配置授权小包数据传输(Configured Grant Small Data Transmission,CG-SDT)资源不能满足待传下行数据的业务需求，或者基站已配置其他终端设备使用相关配置授权资源，此时终端设备再使用CG-SDT资源会造成数据传输时延或冲突。或者基站没有发起增强寻呼，则终端设备缺少判断能否用小包数据传输的信息，导致错误使用小包数据传输响应，基站需要重新迁移终端设备到连接态而造成传输时延。
本发明技术方案中，寻呼消息包括第一指示信息，终端设备可以根据第一指示信息确定是否进行小包数据传输，和/或确定在进行小包数据传输时使用的小包数据传输资源。通过在寻呼消息中携带第一指示信息，使得终端设备能够基于第一指示信息判断能否进行小包数据传输，或者能够选择合适的资源进行小包数据传输，减小传输时延，提升小包数据传输的可靠性。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是提供的一种数据传输方法的流程图。
本发明实施例的数据传输方法可以用于终端设备侧，也即可以由终端设备执行所述方法的各个步骤。具体地，该终端设备处于非激活态(inactive)。
具体地，所述数据传输方法可以包括以下步骤：
步骤101：接收寻呼消息，所述寻呼消息包括第一指示信息；
步骤102：根据所述第一指示信息确定是否进行小包数据传输， 和/或确定在进行小包数据传输时使用的小包数据传输资源。
需要指出的是，本实施例中各个步骤的序号并不代表对各个步骤的执行顺序的限定。
可以理解的是，在具体实施中，所述数据传输方法可以采用软件程序的方式实现，该软件程序运行于芯片或芯片模组内部集成的处理器中。该方法也可以采用软件结合硬件的方式实现，本申请不作限制。
本发明实施例所称小包数据(也可以称为小数据包)是指数据量小于预设门限的数据。该预设门限可以是由通信标准约定的，也可以是由网络设备预先配置并发送给终端设备的，本发明实施例对此不作限制。
本实施例中，第一指示信息可以指示是否进行小包数据传输，和/或指示在进行小包数据传输时使用的小包数据传输资源。具体而言，可以在寻呼消息中增加信元以承载第一指示信息，例如，在寻呼消息中增加一个比特，比特值1表示进行小包数据传输，比特值0表示不进行小包数据传输。
在步骤102的具体实施中，终端设备使用小包数据传输方式所传输的数据可以是针对寻呼消息(paging)的响应信息，该响应信息为上行数据和/或无线资源控制(Radio Resource Control，RRC)消息。
本发明实施例可以应用于网络设备与终端设备之间的寻呼过程。本实施例中的寻呼消息可以是增强早期数据传输寻呼(Mobile Terminated-Early Data Transmission,MT-EDT)，MT-EDT寻呼是指在寻呼消息中携带MT-EDT指示，终端设备收到该寻呼后，可以发起小包数据传输。
在本发明一个非限制性的实施例中，第一指示信息选自以下一种或多种：小包数据传输类型、不可用的配置授权小包数据传输资源、可用的配置授权小包数据传输资源、待传输下行数据的业务信息、待传输下行数据的数据量和第一数值。
具体实施中，小包数据传输类型包括随机接入小包数据传输(Random Access SDT,RA-SDT)和配置授权小包数据传输(CG-SDT)。具体地，随机接入小包数据传输是指在随机接入流程的消息3(Msg3)或者消息A(MsgA)中携带数据(data)。配置授权小包数据传输是指网络给终端设备预配专用的配置授权资源，终端设备使用该资源发送数据。
具体实施中，待传输下行数据的业务信息可以是待传输下行数据的无线承载(Radio Bearer,RB)的信息或逻辑信道(Logical Channel,LCH)的信息。其中，无线承载可以包括数据无线承载(Data Radio Bearer,DRB)和信令无线承载(Signaling Radio Bearer,SRB)进一步的，待传输下行数据的业务信息还可以是待传输下行数据的服务质量(Quality of Service,Qos)信息或业务需求信息。
图2示出了终端设备和网络设备之间的交互流程图。
在步骤201中，网络设备发送寻呼消息至终端设备。寻呼消息中包括第一指示信息。
在步骤202中，终端设备根据第一指示信息确定是否进行小包数据传输，和/或确定在进行小包数据传输时使用的小包数据传输资源。
在步骤203中，终端设备与网络设备之间进行小包数据传输。
在一个具体实施例中，第一指示信息包括小包数据传输类型，小包数据传输类型包括随机接入小包数据传输。也就是说，第一指示信息指示优先进行随机接入小包数据传输。那么，终端设备在接收到寻呼消息后，可以优先使用随机接入小包数据传输资源响应寻呼消息。
对于网络设备而言，可以根据待传输下行数据或当前小区资源分配情况配置第一指示信息包括随机接入小包数据传输。例如，PRACH或随机接入小包数据传输资源负载较轻(负载低于预设门限)，或者该终端设备被分配的配置授权小包数据传输资源被其他终端设备使用，网络设备为该终端设备配置优先使用随机接入小包数据传输资源 响应寻呼消息；或者，该终端设备可用的配置授权小包数据传输资源不满足对应无线承载的业务需求，例如当前可用的配置授权小包数据传输资源不满足该承载对应服务质量的时延需求，则网络设备为该终端设备配置优先使用随机接入小包数据传输资源响应寻呼消息。
本发明实施例中，通过第一指示信息指示优先使用随机接入小包数据传输资源响应寻呼消息，在配置授权小包数据传输资源不可用的情况下，避免终端设备判断授权小包数据传输资源是否可用的过程，减小了数据传输时延。
在另一个具体实施例中，第一指示信息包括不可用的配置授权小包数据传输资源。那么，终端设备在接收到寻呼消息后，可以不选择配置授权小包数据传输资源也即使用随机接入小包数据传输资源进行小包数据传输，或者不选择部分配置授权小包数据传输资源而是使用除不可用的配置授权小包数据传输资源之外的其他配置授权小包数据传输资源进行小包数据传输，或者不使用小包数据传输资源进行寻呼响应。
例如，如果第一指示信息指示配置授权小包数据传输资源不可用，则在选择载波(carrier)后，直接判断两步随机接入或四步随机接入流程中的随机接入小包数据传输资源是否可用，如果可用，则使用随机接入小包数据传输资源进行小包数据传输。
对于网络设备而言，如果某些配置授权小包数据传输资源已经配置给其他终端设备使用，则可以通过第一指示信息向当前终端设备指示上述配置授权小包数据传输资源不可用。
本发明实施例中，通过第一指示信息指示不可用的配置授权小包数据传输资源，使得终端设备能够避免对上述资源进行重复的可用性判断或者使得终端设备能够避免使用不合适的传输资源导致无法传输数据，从而减小了数据传输时延。
在一个非限制性的实施例中，第一指示信息包括待传输下行数据 的业务信息。具体而言，待传输下行数据的业务信息包括无线承载的信息或逻辑信道的信息。其中，无线承载的信息可以是一个或多个无线承载标识，逻辑信道的信息可以是一个或多个逻辑信道标识。进一步的，待传输下行数据的业务信息还可以是待传输下行数据的服务质量信息或业务需求信息。
具体地，终端设备基于无线承载的信息或逻辑信道的信息可以获知下行数据的业务需求，例如业务需求是服务质量(Quality of Service,Qos)时延低于预设值。那么终端设备可以判断配置授权小包数据传输资源是否能够满足上述业务需求，如果能够满足上述业务需求，则该配置授权小包数据传输资源为可用小包数据传输资源，终端设备使用可用小包数据传输资源进行小包数据传输。或者，终端设备基于无线承载的信息或逻辑信道的信息可以获知下行数据的无线承载信息，从而通过与预先配置的允许进行小包数据传输的无线承载信息(可以是上行允许进行小包数据传输的无线承载信息)进行比较，确定是否可以使用小包数据传输的资源响应寻呼消息。
本发明实施例中，通过第一指示信息指示待传输下行数据的业务信息，能够使得终端设备获知待接收的业务需求，从而确定满足业务需求的可用资源，避免使用不满足业务需求的传输资源传输数据，减小了数据传输时延。
在另一个非限制性的实施例中，第一指示信息包括待传输下行数据的数据量。
由于进行小包数据传输的要求是传输的数据量不能太大，例如数据量低于第一门限时才进行小包数据传输，因此终端设备可以基于下行数据的数据量与第一门限的关系来确定是否进行小包数据传输。具体地，数据量达到第一门限(例如数据量大于第一门限，或数据量等于第一门限)，则终端设备确定不进行小包数据传输；否则，终端设备确定进行小包数据传输。
需要说明的是，第一门限可以是由通信标准协议预先约定好的， 或者是由网络设备预先发送给终端设备的，本发明实施例对此不作限制。
本发明实施例中，通过第一指示信息指示待传输下行数据的数据量，能够在网络设备没有发起增强寻呼的情况下，使得终端设备能够有依据判断是否可以使用小包数据传输方式来传输数据，从而避免错误使用小包数据传输响应导致重新迁移到连接态而造成的传输时延，提升数据传输效率。
图3示出了终端设备采用随机接入小包数据传输资源进行数据传输时的交互流程。
在步骤301中，网络设备发送寻呼消息至终端设备。寻呼消息中包括第一指示信息。
具体地，当网络设备有下行数据需要发送给处于非激活态的终端设备，网络设备在RNA范围内的小区寻呼终端设备。
在步骤302中，终端设备根据第一指示信息确定使用随机接入小包数据传输资源进行小包数据传输。
具体地，当终端设备收到寻呼消息后，会在驻留的小区选择公共的物理随机接入信道(Physical Random Access Channel,PRACH)资源，发起随机接入过程(可以使用四步或两步随机接入)。下面步骤303至步骤306示出的是四步随机接入过程。
在步骤303中，终端设备发送消息1(Msg1)至网络设备。消息1中包括前导码。
在步骤304中，网络设备发送消息2(Msg2)至终端设备。
具体地，终端设备通过检测随机接入无线网络临时标识(Random Access-Response Radio Network Temporary Identity,RA-RNTI)加扰的物理下行控制信道(Physical Downlink Control Channel,PDCCH)接收随机接入响应(Random Access Response,RAR)。随机接入响应携带消 息3(Msg3)的调度信息。多个终端设备会选择相同的时频资源和前导码发起随机接入过程，会导致冲突，所以需要进行后两步过程(也即消息3和消息4)，进行冲突解决
在步骤305中，终端设备发送消息3(Msg3)至网络设备。消息3中包括小包数据。具体地，终端设备使用消息2中收到的授权，发送消息3。
在步骤306中，网络设备发送消息4(Msg4)至终端设备。消息4中包括冲突解决标识。
相应地，终端设备如果采用两步随机接入过程，终端设备会在消息A(MsgA)携带前导码和终端设备的标识等信息，网络设备收到后会响应发送消息B(MsgB)。终端设备可以在消息A中携带小包数据，以进行小包数据传输。
在具体实施中，当网络设备将终端设备迁移到非激活态时，会配置一些允许使用小包数据传输的条件，比如配置数据量门限，允许使用小包数据传输的资源块(Resource Block,RB)。如果是使用配置授权小包数据传输资源，则会配置对应的配置授权资源，参考信号接收功率(Reference Signal Receiving Power,RSRP)变化的门限范围，同步信号块(Synchronzation Signal Block,SSB)使用的信号门限等，其中配置授权小包数据传输资源只有在收到无线资源控制(Radio Resource Control,RRC)释放消息的小区使用，一旦小区重选到新小区，终端设备就会释放对应的资源。而随机接入小包数据传输资源是通过每个小区的系统消息配置的，同时还有不同的信号门限。
终端设备有数据需要发送时，则会先判断是否可以进行小包数据传输。例如，待传的数据是否承载在允许的资源块中，待传的数据量是否满足门限，如果不满足，则使用非小包数据传输的随机接入信道(Random Access Channel,RACH)资源。如果满足，则按照配置授权小包数据传输的判断条件进行判断是否能够使配置授权小包数据传输资源，例如，终端设备的追踪区(Track Area，TA)变化是否在有效 范围内，如果终端设备位置改变很大，导致之前追踪区失效，则不能使用配置授权小包数据传输资源。如果终端设备不能使用配置授权小包数据传输资源，则使用随机接入小包数据传输资源进行发送小包数据。
在一个非限制性的实施例中，请参照图4，图4示出了另一种终端设备与网络设备之间的交互流程。本实施例中，第一指示信息包括第一数值。
在步骤401中，网络设备发送寻呼消息至终端设备。寻呼消息中包括第一数值。第一数值可以是由网络设备配置的。
在步骤402中，终端设备生成随机数，以得到第二数值，根据第二数值与第一数值的大小关系确定使用配置授权小包数据传输资源或随机接入小包数据传输资源。
具体地，第二数值大于所述第一数值时，使用所述配置授权小包数据传输资源进行小包数据传输，否则使用随机接入小包数据传输资源进行小包数据传输。或者，在第二数值大于所述第一数值时，使用随机接入小包数据传输资源进行小包数据传输，否则使用所述配置授权小包数据传输资源进行小包数据传输。
在步骤403中，终端设备向网络设备进行小包数据传输。具体地，终端设备使用选定的资源进行小包数据传输。
本发明实施例中，终端设备可以自主判断使用何种小包数据传输资源进行小包数据传输，提升了小包数据传输的灵活性。
在一个非限制性的实施例中，网络设备可以在系统消息或RRC释放消息中携带第一数值，并发送给终端设备。相应地，终端设备接收系统消息或RRC释放消息，由于系统消息或RRC释放消息中携带第一数值，因此终端设备获得第一数值。
