Description

传输数据的方法、终端设备和网络侧设备 技术领域
本发明涉及通信技术领域，并且更具体地，涉及一种传输数据的方法、终端设备和网络侧设备。
背景技术
目前，终端设备在传输数据时，需要获取时间提前量(Timing advance，TA)值，然后使用TA值进行数据传输或接入移动通信系统。在第五代移动通信技术5G新空口(New Radio，NR)原型系统中，终端设备要支持大量的支持小包传输的业务，譬如说物联网(Internet Of Things，IOT)中的终端设备。其中，该支持小包传输的业务的特点是需要传输的包都很小，而每次传输完以后，终端设备会释放与基站的连接(connection release)。当终端设备在进行下次数据传输时，还需要重新获取TA值，才能开始传输数据。这样带来的问题是，对于移动性不强的终端设备，重新获取TA值的过程必然会增大延时，而且还增加了系统的信令开销。基于此，亟需提出一种方法来解决该问题。
发明内容
本发明实施例提供了一种传输数据的方法、终端设备和网络侧设备，能够降低延时，以及减少信令开销。
第一方面，提供了一种传输数据的方法，包括：
确定终端设备满足重用第一时间提前量TA值的预设条件；
根据该第一TA值进行数据传输，其中，该第一TA值是该终端设备上一次数据传输所使用的。
在本发明实施例中，终端设备确定该终端设备满足重用第一TA值的预设条件，并根据该第一TA值进行数据传输，其中，该第一TA值是该终端设备上一次数据传输所使用的，能够降低延时，以及减少信令开销。
可选地，重用第一TA值的预设条件可以与终端设备的位置变化信息相关。
可选地，预设条件可以根据位置变化信息对应的一些量化值进行设定， 比如位置变化信息对应的地理位置值、移动距离值、或者参考信号接收功率(Reference Signal Receiving Power，RSRP)值等。
在本发明实施例中，位置变化信息可以代表终端设备在位置发生变化时所引起的一些可能会随着位置变化而发生变化的信息，比如，发生变化的距离值、发生变化的RSRP值等等，对此不作限定。
可选地，在一些可能的实现方式中，确定终端设备满足重用第一时间提前量TA值的预设条件，包括：
确定该终端设备的当前位置与该终端设备进行上一次数据传输的位置之间的距离不大于距离阈值。
因此，终端设备确定该终端设备满足重用第一TA值的预设条件，并根据该第一TA值进行数据传输，其中，该第一TA值是该终端设备上一次数据传输所使用的，能够降低延时，以及减少信令开销。进一步地，终端设备所满足的预设条件可以通过比较终端设备的移动距离与距离阈值之间的关系来确定。
可选地，在本发明实施例中，“不大于距离阈值”也可以变换为“小于距离阈值”，其大小关系可以按照需要进行设定或调整，对此不作限定。
可选地，在一些可能的实现方式中，该方法还包括：
接收网络侧设备发送的该距离阈值。
这里，该距离阈值可以是接收网络侧设备发送的，也可以是协议里约定好的。
可选地，在一些可能的实现方式中，接收网络侧设备发送的该距离阈值，包括：
接收网络侧设备通过广播消息或信令发送的该距离阈值。
在本发明实施例中，终端设备可以接收基站通过广播消息或专用信令等形式发送的距离阈值，例如，专用信令可以为无线资源控制(Radio Resource Control，RRC)信令，对此不作限定。
可选地，在一些可能的实现方式中，确定终端设备满足重用第一时间提前量TA值的预设条件，包括：
确定该终端设备的信号功率值大于信号功率下限阈值，且小于信号功率上限阈值，其中，该信号功率上限阈值大于该信号功率下限阈值。
可选地，在一些可能的实现方式中，该信号功率值可以是参考信号接收 功率RSRP值，其对应的信号功率上限阈值为RSRP上限阈值，其对应的信号功率下限阈值为RSRP下限阈值。可选地，下面出现的信号功率值亦然。
在本发明实施例中，RSRP值代表终端设备在LTE网络中无线信号强度的关键参数，反应了终端设备所测得的基站信号强度，可以用来描述终端设备的位置变化信息。
因此，终端设备确定该终端设备满足重用第一TA值的预设条件，并根据该第一TA值进行数据传输，其中，该第一TA值是该终端设备上一次数据传输所使用的，能够降低延时，以及减少系统的信令开销。进一步地，终端设备所满足的预设条件可以通过比较终端设备的信号功率值与信号功率上限阈值和信号功率下限阈值来确定。
可选地，在一些可能的实现方式中，该方法还包括：
接收网络侧设备发送的该信号功率上限阈值和该信号功率下限阈值。
可选地，在一些可能的实现方式中，接收网络侧设备发送的该信号功率上限阈值和该信号功率下限阈值，包括：

可选地，在本发明实施例中，该信号功率上限阈值和该信号功率下限阈值也可以是终端设备和网络侧设备在协议里约定好的，对此不作限定。

在预定时间段内，确定该终端设备的信号功率值大于信号功率下限阈值，且小于信号功率上限阈值，其中，该信号功率上限阈值大于该信号功率下限阈值。
可选地，在一些可能的实现方式中，该方法还包括：
接收该网络侧设备发送的指示信息，该指示信息用于指示该预定时间段。
可选地，在一些可能的实现方式中，网络侧设备发送的用于指示终端设备的预定时间段的指示信息，也可以携带于广播消息或信令中。
第二方面，提供了一种传输数据的方法，包括：
接收终端设备在确定该终端设备满足重用第一时间提前量TA值的预设条件时根据该第一TA值传输的数据，其中，该第一TA值是该终端设备上一次数据传输所使用的。
在本发明实施例中，网络侧设备可以接收终端设备根据第一TA值发送的数据，该第一TA值是终端设备上一次传输所使用的。并且，终端设备是在确定其满足重用第一TA值的预设条件时，重用该第一TA值的。这样，网络侧设备无需重新为终端设备计算新的TA值，从而降低了时延，减少了系统的信令开销。
可选地，在一些可能的实现方式中，重用第一TA值的预设条件可以与终端设备的位置变化信息相关。
可选地，在一些可能的实现方式中，在接收终端设备在确定该终端设备满足重用第一TA值的预设条件时根据该第一TA值传输的数据之前，该方法还包括：
向该终端设备发送距离阈值；
其中，接收终端设备在确定该终端设备满足重用第一TA值的预设条件时根据第一时间提前量TA值传输的数据，包括：
接收该终端设备在确定该终端设备的当前位置与该终端设备进行上一次数据传输的位置之间的距离不大于该距离阈值时，根据该第一TA值传输的数据。
可选地，向该终端设备发送距离阈值，包括：
通过广播消息或信令向该终端设备发送该距离阈值。
因此，网络侧设备可以接收终端设备在确定该终端设备满足重用第一TA值的预设条件时根据该第一TA值传输的数据，其中，该第一TA值是该终端设备上一次数据传输所使用的，避免了网络侧设备重新为终端设备计算新的TA值，能够降低延时，减少系统的信令开销。进一步地，网络侧设备可以向终端设备发送距离阈值，以便于终端设备根据距离阈值确定其满足重用第一TA值的预设条件。
可选地，在一些可能的实现方式中，在接收终端设备在确定该终端设备满足重用第一TA值的预设条件时根据该第一TA值传输的数据之前，该方法还包括：
向该终端设备发送信号功率上限阈值和信号功率下限阈值，其中，该信 号功率上限阈值大于该信号功率下限阈值；
其中，接收终端设备在确定该终端设备满足重用第一TA值的预设条件时根据该第一TA值传输的数据，包括：
接收该终端设备在确定该终端设备的参考信号接收功率信号功率值大于信号功率下限阈值，且小于信号功率上限阈值时，根据该第一TA值传输的数据。
可选地，在一些可能的实现方式中，信号功率值可以是参考信号接收功率RSRP值。
可选地，在一些可能的实现方式中，向该终端设备发送信号功率上限阈值和信号功率下限阈值，包括：
通过广播消息或信令向该终端设备发送该信号功率上限阈值和该信号功率下限阈值。
可选地，在一些可能的实现方式中，该方法还包括：
向该终端设备发送指示信息，该指示信息用于指示预定时间段；
其中，该接收终端设备在确定该终端设备满足重用第一TA值的预设条件时根据该第一TA值传输的数据，包括：
接收该终端设备在该预定时间段内，在确定该终端设备的信号功率值大于信号功率下限阈值，且小于信号功率上限阈值时，根据该第一TA值传输的数据。
可选地，在具体实现时，该预定时间段可以理解为网络侧设备为终端设备设定的定时器，譬如在多少分钟内，只要终端设备测得基站信号强度不大于一个范围，则重用第一TA值。
因此，网络侧设备可以接收终端设备在确定该终端设备满足重用第一TA值的预设条件时根据该第一TA值传输的数据，其中，该第一TA值是该终端设备上一次数据传输所使用的，避免了网络侧设备重新为终端设备计算新的TA值，能够降低延时，减少系统的信令开销。进一步地，网络侧设备可以向终端设备发送信号功率上下限阈值，以便于终端设备根据信号功率上下限阈值确定其满足重用第一TA值的预设条件。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
应理解，本发明实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、等目前的通信系统，以及，尤其应用于未来的5G系统或5G新空口(New Radio，NR)原型系统。
还应理解，本发明实施例中，网络侧设备也可以称为网络设备或基站等，基站可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是未来5G网络中的基站设备等，本发明对此并不限定。
还应理解，在本发明实施例中，终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网(Core Network)进行通信，终端设备可称为接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处 理设备、车载设备、可穿戴设备以及未来5G网络中的终端设备等。
图1是一个场景示意图。应理解，为了便于理解，这里引入图1中的场景为例进行说明，但并不对本发明构成限制。图1中示出了终端设备11、终端设备12、终端设备13和基站21。
如图1所示，终端设备11可以与基站21进行通信，终端设备12可以与基站21进行通信，终端设备13与基站21进行通信。或者，终端设备12也可以与终端设备11进行通信。或者，作为另一种情形，终端设备13与基站12进行通信。终端设备在接入移动通信系统或进行数据传输时，需要获取时间提前量(Timing Advance，TA)。其中，该TA值可以表示终端设备与基站的距离，或者，引入TA值是为了上行同步的，便于之后发送上行数据。
TA值的获取过程为：终端设备向基站发送一个已知序列，例如非竞争接入场景或竞争接入场景中的随机接入前导序列(random access preamble)，基站根据该已知序列计算出TA值，并将该TA值发送给终端设备，其中，该TA值可以携带于基站给终端设备发送的随机接入响应消息(Random Access Response，RAR)中。例如，终端设备可以接收基站发送的RAR消息，该RAR消息中包括TA值。可选地，该RAR消息中还可以包括上行授权(UL grant)，其中，该上行授权指示上行传输资源，用于该终端设备发送上行数据；小区临时标识(Temporary C-RNTI，TC-RNTI)信息，用于小区内标识终端设备。
然而，在现有技术中，当终端设备的位置变化范围比较小时，TA值仍然需要在每次进行数据传输时重新计算，重复所述“TA值的获取过程”，然后才能根据获取的TA值开始数据传输，这样会导致一定的延时。此外，由于需要重复所述“TA值的获取过程”，还增加了系统的信令开销。基于此，本专利的终端设备或网络侧设备试图使得终端设备在满足某些条件的情况下，沿用上次数据传输的TA值进行数据传输，以达到降低延时，以及减少信令开销的目的。
图2示出了根据本发明实施例的传输数据的方法200的示意性流程图。该方法200可以由终端设备执行，例如，该终端设备可以是图1中的终端设备11、终端设备12或终端设备13。如图2所示，该方法200包括：
S210，确定终端设备满足重用第一时间提前量TA值的预设条件；
可选地，预设条件可以根据终端设备的位置变化信息对应的一些量化值 进行设定，比如位置变化信息对应的地理位置值、移动距离值、或者参考信号接收功率(Reference Signal Receiving Power，RSRP)值等，对此不作限定。
比如，可选地，可以在协议里约定好RSRP门限值，只要终端设备的RSRP值处于该RSRP门限值内，终端设备就可以确定其位置变化信息满足预设条件。可选地，RSRP门限值也可以是基站指示给终端设备的。
需要说明的是，在本发明实施例中，位置变化信息可以代表终端设备在位置发生变化时所引起的一些可能会随着位置变化而发生变化的信息，比如，发生变化的距离值、发生变化的RSRP值等等，对此不作限定。
S220，根据该第一TA值进行数据传输，其中，该第一TA值是该终端设备上一次数据传输所使用的。
具体而言，在终端设备判断其(比如，位置变化信息)满足重用第一TA值的预设条件时，可以根据该第一TA值进行数据传输，并且，该第一TA值是终端设备在上一次数据传输时所使用的TA值。这样，终端设备可以跳过向网络侧设备发送已知序列的过程，直接使用上一次数据传输的TA值，避免了等待网络侧设备重新计算TA值的过程，能够降低延时，以及减少信令开销。
换言之，终端设备在确定其满足重用第一TA值的预设条件时，可以直接重用上一次传输的TA值。譬如，终端设备在与基站的一次连接建立中获得了TA值，完成数据传输后释放与基站的连接；当下一次终端设备进行接入系统或数据传输时，若终端设备判断其位置变化信息符合预设条件，则可以跳过发送随机接入前导序列(preamble)的过程，直接使用上次获得的TA值接入系统或发送数据，其中，发送数据的所使用的资源可以是基站预先调度(pre-scheduling)的上行授权(UL grant)资源，或者是基于竞争(contention based)随机接入时基站发送的上行授权资源。
可选地，第一TA值可以是终端设备在开机进行初始接入时获取的，例如，在小区附着(attach)时，终端设备会获得第一TA值。
可选地，终端设备与基站建立连接后，在进行数据发送时，可以根据基站的指示对TA值进行更改，从而获取第一TA值。
可选地，第一TA值也可以是终端设备在越区切换(即小区切换)过程中获得的。比如，终端设备在切换到目标小区后，可以获得目标小区的新的 TA值，例如第一TA值。
应理解，在本发明实施例中，终端设备的第一TA值可以通过多种方式进行获取，上述只是举例进行描述，并不对本发明构成限制。
还应理解，在本发明实施例中，不论终端设备是通过哪种方式获取的第一TA值，只要终端设备的位置变化信息满足预设条件，均可以重用该第一TA值。换言之，本发明并不限定第一TA值的获取方式。
在本发明实施例中，终端设备确定该终端设备满足重用第一TA值的预设条件，并根据第一TA值进行数据传输，其中，该第一TA值是该终端设备上一次数据传输所使用的，能够降低延时，以及减少信令开销。
应理解，“第一TA值”引入“第一”只是为了描述方便，并不对本发明构成具体限定。
可选地，作为一个实施例，S210可以包括：
确定该终端设备的当前位置与该终端设备进行上一次数据传输的位置之间的距离不大于距离阈值。
具体而言，终端设备确定位置变化信息满足预设条件可以是：终端设备确定其当前位置与其上一次数据传输的位置之间的距离不大于距离阈值。在满足这个预设条件时，终端设备就可以沿用上一次数据传输的TA值进行数据传输。
例如，若终端设备获取到第一TA值时对应的位置是A，移动后终端设备的位置是B，而B到A的距离小于一个预设的门限值，则终端设备可以重复使用该第一TA值。
应理解，在本发明实施例中，“不大于距离阈值”也可以变换为“小于距离阈值”，其大小关系可以按照需要进行设定或调整，对此不作限定。
需要说明的是，可选地，该距离阈值不限于是终端设备的移动距离对应的距离阈值，也可以表示终端设备移动后所在位置的对应距离的距离阈值。例如，终端设备当前位置B所对应的距离是k，距离阈值为n，而k小于n，则终端设备也可以确定其位置变化信息是满足预设条件的。
可选地，作为一个实施例，该方法200还可以包括：
接收网络侧设备发送的该距离阈值。
具体而言，终端设备可以接收网络侧设备发送的该距离阈值或距离门限值。然后，终端设备在根据该距离阈值判断其移动距离满足预设条件时，根 据第一TA值进行数据传输。
可选地，终端设备在与网络侧设备建立连接后，可以向网络侧设备汇报自己的地理位置信息。网络侧设备可以向终端设备配置地理位置信息范围(比如距离阈值)，使得终端设备的地理位置信息在满足地理位置信息范围时，可以重用TA值。
可选地，接收网络侧设备发送的该距离阈值，包括：
接收网络侧设备通过广播消息或信令发送的该距离阈值。
在本发明实施例中，终端设备可以接收网络侧设备通过广播消息或专用信令等形式发送的距离阈值，例如，专用信令可以为无线资源控制(Radio Resource Control，RRC)信令，对此不作限定。
可选地，在本发明实施例中，该距离阈值也可以是终端设备和网络侧设备在协议里约定好的，对此不作限定。
因此，本发明实施例的传输数据的方法，终端设备确定该终端设备满足重用第一TA值的预设条件，并根据该第一TA值进行数据传输，其中，该第一TA值是该终端设备上一次数据传输所使用的，能够降低延时，以及减少信令开销。进一步地，终端设备所满足的预设条件可以通过比较终端设备的移动距离与距离阈值之间的关系来确定。
可选地，作为一个实施例，S210可以包括：
确定该终端设备的信号功率值大于信号功率下限阈值，且小于信号功率上限阈值，其中，该信号功率上限阈值大于该信号功率下限阈值。
比如，可选地，作为一个实施例，S210可以包括：
确定该终端设备的参考信号接收功率RSRP值大于RSRP下限阈值，且小于RSRP上限阈值，其中，该RSRP上限阈值大于该RSRP下限阈值。
具体而言，终端设备确定位置变化信息满足预设条件可以是：终端设备确定其参考信号接收功率RSRP值大于RSRP下限阈值，且小于RSRP上限阈值，其中，该RSRP上限阈值大于该RSRP下限阈值。在满足这个预设条件时，终端设备也可以沿用上一次数据传输的TA值进行数据传输。
应理解，在本发明实施例中，信号功率值不限于RSRP值，也可以是其他合理的可以表征终端设备重用第一TA值的预设条件的功率值，对此不作限定。
在本发明实施例中，RSRP值代表终端设备在LTE网络中无线信号强度 的关键参数，反应了终端设备测得的基站信号强度，可用来描述终端设备的位置变化信息。
例如，在终端设备根据第一TA值进行上一次数据传输时，终端设备对应的RSRP值为100分贝db，RSRP下限阈值为95db，RSRP上限阈值为105db。那么，只要终端设备对应的RSRP值在95-105db内，均可以采用100db对应的第一TA值进行数据传输。或者，换一种情形，也可以认为，当终端设备的变化值在正负5db之间，均可以重用该第一TA值。
又例如，终端设备可以以基站为中心，进行弧形移动，终端设备所在的位置会有对应的RSRP值。其中，若终端设备在该弧形区域范围内进行移动，则终端设备均可以重用TA值。
可选地，作为一个实施例，该方法200还可以包括：
接收网络侧设备发送的该信号功率上限阈值和该信号功率下限阈值。
比如，可选地，作为一个实施例，该方法200还可以包括：
接收网络侧设备发送的该RSRP上限阈值和该RSRP下限阈值。
具体而言，终端设备可以接收网络侧设备发送的该RSRP上限阈值和该RSRP下限阈值，然后在根据该RSRP上限阈值和该RSRP下限阈值判断终端设备的RSRP值满足预设条件时，根据第一TA值进行数据传输。
可选地，接收网络侧设备发送的该RSRP上限阈值和该RSRP下限阈值，包括：
接收网络侧设备通过广播消息或信令发送的该RSRP上限阈值和该RSRP下限阈值。
在本发明实施例中，终端设备可以接收网络侧设备通过广播消息或专用信令等形式发送的该RSRP上限阈值和该RSRP下限阈值，对此不作限定。
可选地，在本发明实施例中，该RSRP上限阈值和该RSRP下限阈值也可以是终端设备和网络侧设备在协议里约定好的，对此不作限定。
可选地，作为一个实施例，S210还包括：
在预定时间段内，确定该终端设备的信号功率值大于信号功率下限阈值，且小于信号功率上限阈值，其中，该信号功率上限阈值大于该信号功率下限阈值。
比如，可选地，作为一个实施例，S210还包括：
在预定时间段内，确定该终端设备的RSRP值大于RSRP下限阈值，且 小于RSRP上限阈值，其中，该RSRP上限阈值大于该RSRP下限阈值。
具体而言，在预定时间段内，如果终端设备确定其RSRP值大于RSRP下限阈值，且小于RSRP上限阈值，其中，该RSRP上限阈值大于该RSRP下限阈值，那么终端设备可以在该预定时间段内重用第一TA值进行数据传输。
可选地，该方法200还包括：
接收该网络侧设备发送的指示信息，该指示信息用于指示该预定时间段。
具体而言，终端设备可以接收网络侧设备发送的指示信息，该指示信息用于指示该预定时间段。比如，在具体实现时，该预定时间段可以是基站为终端设备设定的定时器，譬如在多少分钟内，只要终端设备测得基站信号强度不大于一个范围，则重用第一TA值。其中，信号强度即可以用终端设备的RSRP值表示，范围可以用RSRP上限阈值和RSRP下限阈值表示。
可选地，在本发明实施例中，网络侧设备发送的用于指示终端设备的预定时间段的指示信息，也可以携带于广播消息或信令中。
应理解，在本发明实施例中，本发明仅以距离阈值、RSRP上限阈值和RSRP下限阈值为例进行说明，终端设备还可以根据其他可以表征终端设备的位置变化范围的合理的信息或指标，对预设条件进行判断，对此不作具体限定。
因此，本发明实施例的传输数据的方法，终端设备确定该终端设备满足重用第一TA值的预设条件，并根据该第一TA值进行数据传输，其中，该第一TA值是该终端设备上一次数据传输所使用的，能够降低延时，以及减少系统的信令开销。进一步地，终端设备所满足的预设条件可以通过比较终端设备的RSRP值与RSRP上限阈值和RSRP下限阈值来确定。
应理解，在本发明的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
