具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
首先,对本申请实施例中涉及的名词进行简单介绍:
RRC状态:
NR中为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定义的一个新 的RRC状态,即RRC_INACTIVE态。
RRC_INACTIVE态(即非激活态):移动性为基于终端设备的小区选择重选,存在核心网(Core Network,CN)与NR之间的连接,UE接入上下文存在某个网络设备上,寻呼由无线接入网(Radio Access Network,RAN)触发,基于RAN的寻呼区域由RAN管理,网络设备侧知道终端设备的位置是基于RAN的寻呼区域级别的。
小数据传输(Small Data Transmission,SDT):
小数据传输是为处于非激活态的终端设备配置的一种数据传输方式。通小数据传输过程,终端设备无需进入连接态,即可完成数据的传输,从而减小终端设备的功耗和开销。
在小数据传输过程中,当不支持在小数据传输过程中传输的数据(可记为non-SDT数据)数据到达时,如何处理到达的non-SDT数据需要做进一步的讨论,本申请针对这一问题,提供有如下的方案。
图1示出了本申请一个示例性实施例提供的通信系统的框图,该通信系统可以包括:接入网12和终端设备14。
接入网12中包括若干个网络设备120。网络设备120可以是基站,所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在LTE系统中,称为eNodeB或者eNB;在5G NR-U系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一描述可能会变化。为方便本申请实施例中,上述为终端设备14提供无线通信功能的装置统称为网络设备。
终端设备14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备,移动台(Mobile Station,MS),终端(terminal device)等等。为方便描述,上面提到的设备统称为终端。网络设备120与终端设备14之间通过某种空口技术互相通信,例如Uu接口。可选的,终端设备14支持在非激活态执行小数据传输过程。
本申请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)系统、先进的长期演进(Advanced Long Term Evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum,LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),车辆间(Vehicle to Vehicle,V2V)通信以及车联网(Vehicle to Everything,V2X)系统等。本申请实施例也可以应用于这些通信系统。
图2示出了本申请一个示例性实施例提供的数据传输方法的流程图。该方法可以应用于如图1示出的通信系统中,该方法包括:
步骤210,在小数据传输过程中,响应于终端设备中有第一数据到达,终端设备与网络设备之间执行目标交互以使得终端设备进入连接态。
在终端设备到达第一数据的情况下,终端设备与网络设备之间执行目标交互,以使得终端设备进入连接态。可以理解的是,终端设备与网络设备之间执行的目标交互包括终端设备与网络设备之间的至少一次交互行为,通过至少一次交互行为,使得终端设备从非激活态回到连接态,以在连接态传输第一数据。
其中,小数据传输过程是非激活态的数据传输过程,第一数据包括不支持在小数据传输过程中传输的数据。
小数据传输是为处于非激活态的终端设备配置的一种数据传输方式,不需要终端设备与网络设备之间建立RRC连接。对于数据量小且传输频率低的终端设备来说,若只能通过连接恢复过程,恢复与网络设备之间的RRC连接之后再进行数据传输,则数据传输完成后又需要回到非激活态,终端设备的功耗较大。通过进行非激活态下的小数据传输过程,终端设备能够避免进行RRC状态的转换,从而减少终端设备的功耗。
可选的,小数据传输过程包括:基于配置授权(Configured Grant,CG)的小数据传输过程;或,基于随机接入信道(Random Access Channel,RACH)的小数据传输过程。其中,基于RACH的小数据传输过程可以是基于2步RACH的小数据传输过程,也可以是基于4步RACH的小数据传输过程。
可选的,网络设备为终端设备配置允许执行小数据传输的DRB信息,基于DRB信息,终端设备处到达的数据可能是支持在小数据传输过程中传输的数据,也可能是不支持在小数据传输过程中传输的数据(即第一数据)。
可选的,终端设备基于连接恢复指示确定终端设备中有第一数据到达;连接恢复指示是终端设备中的RRC层接收到的,由高层发送的指示。也即,终端设备在执行小数据传输过程中,RRC层收到高层触发的连接恢复指示,通过层间交互,终端设备判断当前有第一数据到达。
可选的,小数据传输过程对应有第一定时器,在终端设备发起小数据传输过程时,启动第一定时器。可选的,终端设备判断是否满足非激活态传输条件,若满足则发起小数据传输过程,本申请实施例对非激活态传输条件的具体内容不进行限定。
步骤220,处于连接态的终端设备传输第一数据。
在通过目标交互进入连接态后,处于连接态的终端设备传输第一数据。
其中,第一数据包括不支持在小数据传输过程中传输的数据。也即,第一数据是一种需要终端设备在连接态下进行传输的数据。
步骤230,网络设备接收第一数据。
网络设备接收处于连接态的终端设备发送的第一数据。
综上所述,本申请实施例提供的方法,第一数据包括不支持在小数据传输过程中传输的数据,在处于小数据传输过程中的终端设备有第一数据到达的情况下,终端设备与网络设备之间通过执行目标交互,以使得终端设备由非激活态回到连接态,并在连接态传输第一数据,从而保障了第一数据的成功传输。
在基于图2的可选实施例中,终端设备与网络设备之间执行的目标交互存在如下2种不同的方案。
1)终端设备向网络设备发起连接恢复过程,以使得终端设备进入连接态。
可选的,终端设备在小数据传输过程结束之后,通过发送连接恢复请求的方式发起连接恢复过程。
2)终端设备通过上行小数据传输向网络设备发送第一数据到达指示,以使得终端设备进入连接态。
其中,第一数据到达指示用于通知网络设备终端设备处有第一数据到达,上行小数据传输是小数据传输过程中的上行数据传输。
在小数据传输过程中,终端设备在上行小数据传输中携带第一数据到达指示,第一数据 到达指示用于通知网络设备终端设备到达第一数据,以便于网络设备及时指示终端设备进行RRC状态的改变,从而使得终端设备尽快进入连接态以传输第一数据。
下面,针对上述两种终端设备与网络设备之间执行目标交互,以使得终端设备恢复连接态的不同的方案,分别进行示例性的说明。
1)终端设备向网络设备发起连接恢复过程,以使得终端设备进入连接态。
在基于图2的可选实施例中,图3示出了本申请一个示例性实施提供的数据传输方法的流程图。该方法可以应用于如图1示出的通信系统中,该方法包括如下步骤:
步骤310,终端设备发送连接恢复请求。
终端设备通过发送连接恢复请求的方式发起连接恢复过程。其中,连接恢复请求用于请求网络设备恢复RRC连接,以使得终端设备回到连接态。可选的,终端设备发送连接恢复请求是在小数据传输过程结束之后,且终端设备处于非激活态。
可选的,小数据传输过程对应有第一定时器;响应于处于小数据传输过程的终端设备到达第一数据,终端设备确定第一定时器的状态;响应于第一定时器不处于运行状态,发送连接恢复请求。
其中,第一定时器是用于小数据传输过程的失败检测的定时器,在第一定时器的运行期间,终端设备执行小数据传输过程的相关功能。第一定时器不处于运行状态,则意味着小数据传输过程已结束。相应的,响应于第一定时器处于运行状态,则意味着小数据传输过程正在进行,则终端设备不执行发送连接恢复请求的步骤。
可以理解的是,响应于第一定时器不处于运行状态,终端设备可以再进一步确定当前的RRC状态,在RRC状态为非激活态的情况下,再发送连接恢复请求。
可选的,第一定时器不处于运行状态,包括如下两种情况中的任意一种:
一、第一定时器运行超时。
可选的,第一定时器对应有预设的运行时长,在第一定时器运行达到运行时长的情况下,第一定时器运行超时。
可选的,在第一定时器运行超时的情况下,终端设备可以认为小数据传输过程失败,则终端设备发送连接恢复请求。
二、第一定时器在网络设备发送的第一消息的触发下终止。
可选的,在步骤310之前,网络设备发送第一消息,终端设备相应接收第一消息。
可选的,第一定时器对应有预设的运行时长,在第一定时器运行未达到运行时长的情况下,终端设备接收到网络设备发送的第一消息,则第一定时器终止,小数据传输过程结束。
其中,第一消息用于指示终端设备结束小数据传输过程。可选的,第一消息还用于指示终端设备的RRC状态。

其中,第一定时器是用于小数据传输过程的失败检测的定时器,在第一定时器的运行期间,终端设备执行小数据传输过程的相关功能。响应于第一定时器处于运行状态,终端设备生成第一数据到达指示,以在小数据传输过程中通知网络设备终端设备处到达第一数据。相应的,响应于第一定时器不处于运行状态,则终端设备不生成第一数据到达指示。

步骤550,终端设备接收第二消息,基于第二消息中的连接态指示进入连接态。
终端设备接收网络设备发送的第二消息,基于第二消息结束小数据传输过程,并根据第二消息中的连接态指示进入连接态。
