Description

缓存状态报告BSR上报触发方法、装置和用户终端
本申请基于申请号为201611258460.X、申请日为2016年12月30日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开涉及智能终端设备技术领域，尤其涉及一种缓存状态报告BSR上报触发方法、装置和用户终端。
背景技术
在长期演进(Long Term Evolution，简称LTE)中，用户终端(User Equipment，简称UE)通过向演进型Node B(Evolved Node B，简称eNodeB)发送缓存状态报告(Buffer Status Report，简称BSR)来表示用户终端的上行缓存中有多少数据需要发送，以便eNodeB给用户终端分配上行资源，以供用户终端通过该上行资源向eNodeB发送上行数据。
现有技术中，用户终端向eNodeB发送BSR的触发方式有多种，其中一种是用户终端周期性的向eNodeB发送BSR，例如，当用户终端有大量数据要发送时，数据持续的进入用户终端的上行缓存，用户终端可周期性的向eNodeB发送BSR，周期性的通知eNodeB用户终端的上行缓存中有多少数据需要发送。
但是对于用户终端周期性的向eNodeB发送BSR，如果用户终端向eNodeB发送BSR的周期较小，会造成较大的网络开销，如果用户终端向eNodeB发送BSR的周期较大，即用户终端前一次向eNodeB发送BSR的时刻与用户终端下一次向eNodeB发送BSR的时刻之间的时间间隔较大，可能会导致基站根据用户终端前一次发送的BSR，给用户终端分配上行资源后，上行资源很快被用户终端用于发送上行数据，由于前后两次发送BSR的时间间隔较大，当前一次分配的上行资源全部被用于发送上行数据后，用户终端无法即时获取到新的上行资源，导致用户终端无法将上行缓存中的数据即时的发送给eNodeB，造成上行数据的较大延时。

通过上述附图，已示出本公开明确的实施例，后文中将有更详细的描述。这些附图和文字描述并不是为了通过任何方式限制本公开构思的范围，而是通过参考特定实施例为本领域技术人员说明本公开的概念。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种缓存状态报告BSR上报触发方法实施例一的流程图，该方法可以由缓存状态报告BSR上报触发装置来执行，该缓存状态报告BSR上报触发装置可以集成在用户终端中，如图1所示，该方法包括以下步骤：
在步骤101中，获取用户终端上报给基站的所述用户终端需要发送的数据量。
本实施例中，用户终端(User Equipment，简称UE)通过向演进型Node B(Evolved Node B，简称eNodeB)发送缓存状态报告(Buffer Status Report，简称BSR)来表示用户终端的上行缓存中有多少数据需要发送。在用户终端向基站例如eNodeB发送BSR之前，用户终端需要统计其上行缓存中有多少数据需要发送。
在步骤102中，获取所述基站根据所述数据量给所述用户终端分配的上行资源大小。
基站例如eNodeB接收到用户终端发送的BSR之后，基站给用户终端分配上行资源，以便用户终端利用该上行资源向eNodeB发送上行数据。
在步骤103中，若所述数据量与所述上行资源大小的差值小于预设门限值，则触发所述用户终端向所述基站上报缓存状态报告BSR。
当用户终端有大量数据要发送时，用户终端向基站发送过一次BSR之后，基站的逻辑信道或逻辑信道组还会持续产生新的数据，用户终端还需要为新的数据向基站申请上行资源，本公开实施例中，提出了用户终端向基站发送过一次BSR之后，再次向基站发送BSR的触发条件，可选的，该触发条件是用户终端需要发送的数据量比基站给用户终端分配的上行资源大，且该数据量与该上行资源大小的差值小于预设门限值。可选的，用户终端需要发送的数据量用M表示，可选的，M非零；基站给用户终端分配的上行资源用X 表示，则触发条件可表示为公式(1)：
M-X＜threshold      (1)
其中，threshold为预设门限值，即满足公式(1)时，即触发用户终端向基站上报缓存状态报告BSR。
本实施例中，通过比较用户终端需要发送的数据量和基站根据该数据量给用户终端分配的上行资源大小，判断是否触发用户终端向基站上报BSR，具体的，若用户终端需要发送的数据量比基站给用户终端分配的上行资源大，且该数据量与该上行资源大小的差值小于预设门限值，则触发用户终端向基站上报BSR，即当用户终端有大量数据要发送时，根据用户终端需要发送的数据量与基站给用户终端分配的上行资源大小的差值，即可判断是否触发用户终端向基站上报BSR，使得用户终端不需要周期性的向eNodeB发送BSR，避免了周期较小造成网络开销大的问题，同时也避免了周期较大造成上行数据延时较大的问题。
图2是根据一示例性实施例示出的一种缓存状态报告BSR上报触发方法实施例二的流程图，如图2所示，该方法可以包括如下的步骤：
在步骤201中，获取所述用户终端在相对于当前时刻的前一次上报给所述基站的所述BSR指示的缓存大小范围。
在本实施例中，所述用户终端需要发送的数据量为所述缓存大小范围的最小值或最大值。
在本实施例中，可选的，在历史时刻t1，用户终端已经向基站上报过一次BSR，在历史时刻t1之后到当前时刻t2之间，用户终端没有向基站上报过BSR，则历史时刻t1可作为用户终端在距离当前时刻最近一次上报BSR的时刻。
在其他实施例中，在历史时刻t1，用户终端向基站上报BSR的触发方式可以是现有技术中的任意一种。
用户终端向基站上报的BSR包括逻辑信道组标识字段和缓存大小字段，其中，逻辑信道组标识字段用于指示用户终端向基站上报的BSR对应的逻辑信道组的标识信息，缓存大小字段用于指示缓存大小范围，该缓存大小范围可用于近似表示用户终端的上行数据量。
在本实施例中，获取用户终端在历史时刻t1上报给基站的BSR，从该BSR中获取缓存大小字段指示的缓存大小范围，将该缓存大小范围对应的最小值或最大值作为历史时刻t1用户终端需要发送的数据量，即该缓存大小范围对应的最小值或最大值作为上述实施例中的M，可选的，M非零。
在步骤202中，获取所述用户终端在相对于当前时刻的前一次向所述基站上报所述BSR的时刻到当前时刻之间，所述基站给所述用户终端分配的上行资源大小。
由于在历史时刻t1之后到当前时刻t2之间，用户终端没有向基站上报过BSR，则历 史时刻t1用户终端向基站发送BSR后，基站给用户终端分配上行资源，在其他实施例中，在历史时刻t1到当前时刻t2之间，基站可多次给用户终端分配上行资源。在本实施例中，统计历史时刻t1到当前时刻t2之间，基站给用户终端分配的上行资源大小，可选的，将历史时刻t1到当前时刻t2之间，基站给用户终端分配的上行资源大小作为上述实施例中的X。
在步骤203中，若所述数据量与所述上行资源大小的差值小于预设门限值，则触发所述用户终端在当前时刻向所述基站上报缓存状态报告BSR。
在本实施例中，可选的，在当前时刻t2判断用户终端是否满足上述实施例所述的触发条件即公式(1)，若满足，则触发用户终端在当前时刻t2向基站上报缓存状态报告BSR。
本实施例中，通过获取用户终端在前一次上报给基站的BSR指示的缓存大小范围，确定用户终端在前一次上报BSR时，用户终端需要发送的数据量，同时统计用户终端在前一次向基站上报BSR的时刻到当前时刻之间，基站给用户终端分配的上行资源大小，根据该数据量和该上行资源大小，确定是否触发用户终端在当前时刻向基站上报BSR，实现了对用户终端向基站上报BSR的触发条件的实时判断。
图3是根据一示例性实施例示出的一种缓存状态报告BSR上报触发方法实施例三的流程图，如图3所示，该方法可以包括如下步骤：
在步骤301中，获取所述用户终端在相对于当前时刻的前一次向所述基站上报所述BSR时，所述用户终端的上行缓存的实际缓存大小。
在上述实施例的基础上，可选的，在历史时刻t1，用户终端已经向基站上报过一次BSR，在历史时刻t1之后到当前时刻t2之间，用户终端没有向基站上报过BSR，则历史时刻t1可作为用户终端在距离当前时刻最近一次上报BSR的时刻。
在本实施例中，可选的，将历史时刻t1用户终端的上行缓存的实际缓存大小作为历史时刻t1用户终端需要发送的数据量，即将历史时刻t1用户终端的上行缓存的实际缓存大小作为上述实施例中的M，可选的，M非零。
在步骤302中，获取所述用户终端在相对于当前时刻的前一次向所述基站上报所述BSR的时刻到当前时刻之间，所述基站给所述用户终端分配的上行资源大小。
由于在历史时刻t1之后到当前时刻t2之间，用户终端没有向基站上报过BSR，则历史时刻t1用户终端向基站发送BSR后，基站给用户终端分配上行资源，在其他实施例中，在历史时刻t1到当前时刻t2之间，基站可多次给用户终端分配上行资源。在本实施例中，统计历史时刻t1到当前时刻t2之间，基站给用户终端分配的上行资源大小，可选的，将历史时刻t1到当前时刻t2之间，基站给用户终端分配的上行资源大小作为上述实施例中的X。
在步骤303中，若所述数据量与所述上行资源大小的差值小于预设门限值，则触发所述用户终端在当前时刻向所述基站上报缓存状态报告BSR。
在本实施例中，可选的，在当前时刻t2判断用户终端是否满足上述实施例所述的触发条件即公式(1)，若满足，则触发用户终端在当前时刻t2向基站上报缓存状态报告BSR。
在本实施例中，公式(1)中的预设门限值threshold根据所述用户终端的不同逻辑信道确定，或者所述预设门限值根据所述用户终端的不同逻辑信道组确定，或者所述预设门限值根据所述用户终端的所有逻辑信道确定。可选的，用户终端需要发送的数据量即用户终端的上行缓存中需要发送的数据量M可以逻辑信道为单位进行统计，或者以逻辑信道组为单位进行统计，或者以用户终端的所有逻辑信道进行统计。相应的，当用户终端以逻辑信道为单位统计需要发送的数据量M时，不同的逻辑信道对应的threshold不同；当用户终端以逻辑信道组为单位统计需要发送的数据量M时，不同的逻辑信道组对应的threshold不同；当用户终端以所有逻辑信道统计需要发送的数据量M时，所有逻辑信道组或所有逻辑信道共用一个threshold。
本实施例中，将用户终端在前一次向基站上报BSR时，用户终端的上行缓存的实际缓存大小作为用户终端需要发送的数据量，精确了用户终端需要发送的数据量的计算方法，提高了对用户终端向基站上报BSR的触发条件的判断精确。

获取所述基站根据所述数据量给所述用户终端分配的上行资源大小；
若所述数据量与所述上行资源大小的差值小于预设门限值，则触发所述用户终端向所述基站上报缓存状态报告BSR。
本实施例中，通过比较用户终端需要发送的数据量和基站根据该数据量给用户终端分配的上行资源大小，判断是否触发用户终端向基站上报BSR，具体的，若用户终端需要发送的数据量比基站给用户终端分配的上行资源大，且该数据量与该上行资源大小的差值小于预设门限值，则触发用户终端向基站上报BSR，即当用户终端有大量数据要发送时，根据用户终端需要发送的数据量与基站给用户终端分配的上行资源大小的差值，即可判断是否触发用户终端向基站上报BSR，使得用户终端不需要周期性的向eNodeB发送BSR，避免了周期较小造成网络开销大的问题，同时也避免了周期较大造成上行数据延时较大的问题。
