图1是根据一示例性实施例示出的一种数据传输方法的流程图,图2是根据一示例性实施例示出的一种数据传输方法的场景图;该数据传输方法可以用于终端。如图1所示,该数据传输方法包括以下步骤110-130:
在步骤110中,当检测到待传输至基站的上行数据时,则将该上行数据保存在指定缓存中。
本公开实施例中,终端可以是处于非活动状态(inactive state)的终端。
该终端检测到待传输至基站的上行数据时,会先将这些上行数据先保存在指定缓存中,等到该终端开始进行RLAU(Radio Access Network Location Area Update,无线接入网位置区域更新)时,再将这些上行数据随同RLAU对应的请求信令传输至基站。其中,指定缓存可以是终端自身的缓存(buffer)。
在步骤120中,当开始进行RLAU时,则从指定缓存中读取上行数据。
在步骤130中,通过RLAU对应的请求信令将上行数据传输至基站,以使该基站从接收到的请求信令中获取上行数据。
本公开实施例中,RLAU对应的请求信令是终端发送至基站的请求信令。该请求信令可以是终端向基站发送的随机接入请求信令,还可以是终端向基站发送的RRC(Radio Resource Control,无线资源控制协议)连接恢复请求信令。
在一实例性场景中,如图2所示,包括基站和终端,并以通过RRC连接恢复请求信令将上行数据传输至基站为例,来说明该终端向基站传输上行数据的过程:
(1)终端保存上传数据。其中,当终端检测到待传输至基站的上行数据时,会将该上行数据保存在本地缓存中。
(2)终端开始进行RLAU。其中,当终端开始进行RLAU时,会从本地缓存中读取上行数据。
(3)终端向基站发送随机接入请求信令。
(4)基站向终端发送随机接入响应指令。
(5)终端向基站发送RRC连接恢复请求信令,且该RRC连接恢复请求信令中包括上行数据。
(6)基站向终端发送RRC连接恢复响应指令。
由上述实施例可见,当终端检测到待传输至基站的上行数据时,可以先将该上行数据保存在指定缓存中,等到开始进行RLAU时,再从指定缓存中读取上行数据,并通过RLAU对应的请求信令将上行数据传输至基站,从而实现了RLAU流程与数据传输的结合,使得基站能够接收处于非活动状态的终端传输的上行数据,还提高了数据传输的效率。
在一实施例中,上述步骤120中的RLAU,可以是指定事件触发的RLAU,还可以是周期触发的RLAU。
其中,指定事件可以包括但不限于以下这种情形:
终端从一个RNA(Radio Access Network based Notification Area,无线接入网通知区域)移动到另一个RNA。
由上述实施例可见,当终端开始进行指定事件触发的RLAU、或周期触发的RLAU时,均可以将实现上行数据的传输,从而提高了数据传输的可靠性。
在一实施例中,如图3所示,上述步骤130中的请求信令可以为RRC连接恢复请求信令,在执行步骤130中通过RLAU对应的请求信令将上行数据传输至基站时,可以包括以下步骤310-320:
在步骤310中,将上行数据添加到RRC连接恢复请求信令中。
在步骤320中,将带有上行数据的RRC连接恢复请求信令发送至基站。
由上述实施例可见,当开始进行RLAU后,可以将上行数据添加到RRC连接恢复请求信令中,并将带有上行数据的RRC连接恢复请求信令发送至基站,从而丰富了上行数据的传输方式,提高了数据传输的实用性。
在一实施例中,如图4所示,上述步骤130中的请求信令可以为随机接入请求信令,在执行步骤130中通过RLAU对应的请求信令将上行数据传输至基站时,可以包括以下步骤410-420:
在步骤410中,将上行数据添加到随机接入请求信令中。
在步骤420中,将带有上行数据的随机接入请求信令发送至基站。
由上述实施例可见,当开始进行RLAU后,可以将上行数据添加到随机接入请求信令中,并将带有上行数据的随机接入请求信令发送至基站,从而丰富了上行数据的传输方式,提高了数据传输的实用性。
在一实施例中,上述步骤420中的随机接入请求信令还可以包括RRC连接恢复请求信令。
此方式下,终端可以将上行数据和RRC连接恢复请求信令都添加到随机接入请求信令中,然后再将该随机接入请求信令发送至基站。
由上述实施例可见,当开始进行RLAU后,可以将上行数据和RRC连接恢复请求信令都添加到随机接入请求信令中,然后再将该随机接入请求信令发送至基站,从而简化了RLAU流程,也提高了数据传输的速度。
在一实施例中,该数据传输方法还可以从基站发送的响应指令中获取下行数据,其实现方式可以采用但不限于以下任一方式:
第一方式,当接收到基站发送的RRC连接恢复响应信令,且该RRC连接恢复响应信令中携带有基站待传输至终端的下行数据时,则从该RRC连接恢复响应信令获取下行数据。
第二方式,当接收到所述基站发送的随机响应信令,且该随机响应信令中携带有基站待传输至终端的下行数据时,则从该随机响应信令中获取下行数据。
由上述实施例可见,由于基站发送的RRC连接恢复响应信令、或随机响应信令中携带有下行数据,这样终端就可以从RRC连接恢复响应信令、或随机响应信令中 获取下行数据,而不用去监听基站的寻呼信令,从而丰富了终端获取下行数据的方式,还提高了终端获取下行数据的效率。
图5是根据一示例性实施例示出的一种数据传输方法的流程图,图6是根据一示例性实施例示出的一种数据传输方法的场景图;该数据传输方法可以用于基站。如图5所示,该数据传输方法包括以下步骤510-530:
在步骤510中,当检测到待传输至终端的下行数据时,则将该下行数据保存在指定缓存中。
本公开实施例中,终端可以是非活动状态下的终端。
当基站检测到待传输至该终端的下行数据时,基站会先将这些下行数据先保存在指定缓存中,等到该终端开始进行RLAU时,再将这些下行数据随同RLAU对应的响应信令传输至该终端。其中,指定缓存可以是基站自身的缓存(buffer)。
在步骤520中,当检测到终端开始进行RLAU时,则从指定缓存中读取下行数据。
本公开实施例中,
在步骤530中,通过RLAU对应的响应信令将该下行数据传输至终端,以使终端从响应信令中获取下行数据。
本公开实施例中,RLAU对应的请求信令是基站发送至终端的响应信令。该响应信令可以是基站向终端发送的随机接入响应信令,还可以是基站向终端发送的RRC连接恢复响应信令。
在一实例性场景中,如图6所示,包括基站和终端,并以通过RRC连接恢复响应信令将下行数据传输至基站为例,来说明该基站向终端传输下行数据的过程:
(1)基站保存下行数据。其中,当基站检测到待传输至终端的下行数据时,会将该下行数据保存在本地缓存中。
(2)终端开始进行RLAU。其中,当终端开始进行RLAU时,基站会从本地缓存中读取下行数据。
(3)终端向基站发送随机接入请求指令。
(4)基站向终端发送随机接入响应信令。
(5)终端向基站发送RRC连接恢复请求信令。
(6)基站向终端发送RRC连接恢复响应指令,且该RRC连接恢复响应指令包括下行数据。
由上述实施例可见,当基站检测到待传输至终端的下行数据时,不是触发寻呼,而是可以先将该下行数据保存在指定缓存中,等到检测到终端开始进行RLAU时,再从指定缓存中读取下行数据,并通过RLAU对应的响应信令将下行数据传输至终端,从而实现了RLAU流程与数据传输的结合,使得基站可以向处于非活动状态的终端传输下行数据,还提高了数据传输的效率。
在一实施例中,上述步骤520中的RLAU,可以是指定事件触发的RLAU,还可以是周期触发的RLAU。
其中,指定事件可以包括但不限于以下这种情形:
终端从一个RNA(Radio Access Network based Notification Area,无线接入网通知区域)移动到另一个RNA。
另外,上述步骤520中检测到终端开始进行RLAU时,可以采用不限于以下方式:
当接收到终端发送的随机接入请求信令时,根据该随机接入请求信令可以确定检测到终端开始进行RLAU。
由上述实施例可见,当终端开始进行指定事件触发的RLAU、或周期触发的RLAU时,均可以将实现下行数据的传输,从而提高了数据传输的可靠性。
在一实施例中,如图7所示,上述步骤530中的响应信令可以为RRC连接恢复响应信令,在执行步骤530中通过RLAU对应的响应信令将该下行数据传输至终端时,可以包括以下步骤710-720:
在步骤710中,将下行数据添加到RRC连接恢复响应信令中。
在步骤720中,将带有下行数据的RRC连接恢复响应信令发送至终端。
由上述实施例可见,当终端开始进行RLAU后,基站可以将下行数据添加到RRC连接恢复响应信令中,并将带有下行数据的RRC连接恢复响应信令发送至终端,从而丰富了下行数据的传输方式,提高了数据传输的实用性。
在一实施例中,如图8所示,上述步骤530中的请求信令可以为随机接入响应 信令,在执行步骤530中通过RLAU对应的响应信令将该下行数据传输至终端时,可以包括以下步骤810-820:
