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发明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、本发明的一些方面相一致的装置和方法的例子。
相关技术中，对于新空口(NR)系统，用户设备当需要通过已有的PDU会话上传新数据时，按照PDCP协议的规定，通过门限进行判决。若待上传数据的数据量小于预设的门限，则仅向MCG对应的MAC层发送待上传数据。若待上传数据的数据量不小于预设的门限，则向MCG和SCG对应的MAC层均发送待上传数据。
本公开的发明人发现，需要在已有的会话上传输新数据时，无论小于门限还是不小于门限，都会上传数据，只是上传的路径不同。相关技术中未提供屏蔽上传的机制。上传数据的控制机制不够完整。本实施例在这种情况下增加了接入等级禁止(Access Class Barring，ACB)检测，在存在接入等级禁止检测的结果为阻塞的小区组时，屏蔽向该小区组传输新数据。完善了上传数据的控制机制。
图1是根据一示例性实施例示出的一种数据传输控制方法的流程图，该数据传输控制方法用于用户设备中，其中，用户设备可以是移动电话，计算机，数字广播终端，消息收发设备，游戏控制台，平板设备，医疗设备，健身设备，个人数字助理等。如图1所示，该方法包括以下步骤101-102。
在步骤101中，当需要在已有的会话上传输新数据时，对PDCP实体关联的多个小区组中的每个小区组，进行接入等级禁止检测。
在步骤102中，在存在接入等级禁止检测的结果为阻塞的小区组时，屏蔽向该小区组传输新数据。
在存在接入等级禁止检测的结果不为阻塞的小区组(Cell Group，CG)时，向不为阻塞的小区组传输新数据。
本实施例中，适用于连接态的用户设备(UE)，在UE需要通过已经有PDU会话上逻辑信道参数或数据无线承载上传数据时，如果已经有PDU会话且尚未过期，以及关联的RLC(Radio Link Control，无线链路控制)实体位于多个小区组，则可以通过该已有的PDU会话上传新数据。但是在通过PDU会话上传新数据之前，需要进行接入等级禁止检测。
本实施例可以针对关联的每个小区组，分别进行接入等级禁止检测，对于检测的结果为阻塞(bar)的小区组，屏蔽向该小区组传输新数据。
其中，关联的多个小区组包括MCG和SCG。
本实施例中，接入等级禁止检测可由UE中的多个用户面实现，参见下面的实施例。
在一个实施例中，所述步骤101包括：步骤A1和步骤A2，或者步骤A3和步骤A4。
在步骤A1中，RRC层对PDCP实体关联的多个小区组中的每个小区组，进行接入等级禁止检测。
在步骤A2中，RRC层将接入等级禁止检测的结果发送给PDCP层。
本实施例中由RRC层完成接入等级禁止检测，将检测结果发送给PDCP层。
在步骤A3中，RRC层将进行接入等级禁止检测所需的接入控制禁止参数发送给PDCP层。
在步骤A4中，PDCP层根据收到的接入控制禁止参数，对PDCP实体关联的多个小区组中的每个小区组，进行接入等级禁止检测。
本实施例中由PDCP层完成接入等级禁止检测，RRC层预先将检测所需要的接入控制禁止参数发送给PDCP层。
在一个实施例中，所述方法还包括：步骤B1。
在步骤B1中，接收网络侧发送的专用信令，所述专用信令包括接入控制禁止参数。
所述步骤101包括：步骤B2。
在步骤B2中，根据收到的接入控制禁止参数，对PDCP实体关联的多个小区组中的每个小区组，进行接入等级禁止检测。
本实施例中UE预先接收网络侧(如基站)发送的专用信令，如RRC信令或MAC CE(MAC Control Element，媒体接入层控制单元)信令等，该专用信令包括接入控制禁止参数。接入控制禁止参数用于接入等级禁止检测。
接入控制禁止参数包括：接入标识(access identities)、接入类别(access category)、禁止因子(barring factor)和禁止时长等。接入标识用于标记用户，接入类别用于标记业务。禁止因子用于接入等级禁止检测。禁止时长用于接入等级禁止计时器。
每个用户的各个业务可以对应各自的禁止因子。用户设备可以通过随机生成禁止因子，网络侧可以通过专用信令下发一个或多个禁止因子。如果用户设备随机生成的禁止因子小于网络侧下发的禁止因子，则检测结果为不阻塞，反之为阻塞。由此可知，网络侧可以通过配置禁止因子来控制上行数据传输。
UE中的RRC层会先收到接入控制禁止参数，如果采用由RRC层进行接入等级禁止检测，则RRC可以直接进行检测。如果采用由PDCP层完成接入等级禁止检测，则需要RRC层将检测所需要的接入控制禁止参数发送给PDCP层。
在一个实施例中，所述接入控制禁止参数包括所述每个小区组对应的逻辑信道参数或数据无线承载(DRB)禁止的参数。
所述步骤101包括：步骤C1或步骤C2。
在步骤C1中，针对每个小区组对应的逻辑信道，根据相应的逻辑信道参数，进行接入等级禁止检测。
本实施例可以针对小区组中的各个逻辑信道进行接入等级禁止检测，实现逻辑信道级别的接入等级禁止检测。如果检测结果为阻塞，则屏蔽在该逻辑信道上传数据。如果检测结果为不阻塞，则可以继续在该逻辑信道上传数据。当然，相应的，接入控制禁止参数包括所述每个小区组对应的逻辑信道参数。
在步骤C2中，针对每个小区组对应的数据无线承载，根据相应的数据无线承载禁止的参数，进行接入等级禁止检测。
本实施例可以针对小区组中的各个DRB进行接入等级禁止检测，实现DRB级别的接入等 级禁止检测。如果检测结果为阻塞，则屏蔽在该DRB上传数据。如果检测结果为不阻塞，则可以继续在该DRB上传数据。当然，相应的，接入控制禁止参数包括所述每个小区组对应的DRB禁止的参数。
网络侧可以通过逻辑信道参数或数据无线承载禁止的参数来控制UE进行接入等级禁止检测的粒度。
在一个实施例中，所述多个小区组包括主小区组和辅小区组。
所述步骤101包括：步骤D1和步骤D2。
在步骤D1中，当需要在已有的会话上采用分裂承载机制传输新数据时，对主小区组进行接入等级禁止检测。
在步骤D2中，对辅小区组应用主小区组的接入等级禁止检测的结果。
本实施例中，分裂承载机制(split case)是指MCG与SCG传输不同的数据。
本实施例中，当采用分裂承载机制时，可以对主小区组进行接入等级禁止检测。而不需要对辅小区组进行接入等级禁止检测，直接采用主小区组的接入等级禁止检测的结果。在分裂承载机制下，专用信令可以携带辅小区组的接入控制禁止参数，也可以不携带辅小区组的接入控制禁止参数。在一个实施例中，收到的接入控制禁止参数不包括辅小区组对应的接入控制禁止参数。可以节省网络资源。
当采用PDCP复制机制(PDCP duplication case)，即主小区组和辅小区组可以发送相同的数据时，可以对主小区组和辅小区组分别进行接入等级禁止检测，应用各自的检测结果。当然，也可以对主小区组进行接入等级禁止检测。而不需要对辅小区组进行接入等级禁止检测，直接采用主小区组的接入等级禁止检测的结果。
在一个实施例中，所述步骤102包括：步骤E。
在步骤E中，PDCP层取消向结果为阻塞的小区组传输新数据。
本实施例中，屏蔽新数据的传输可以有多种措施，措施之一是，用户设备中的PDCP层取消向结果为阻塞的小区组传输新数据。在PDCP层实现了屏蔽新数据的传输，缓解该小区组的拥塞。
在一个实施例中，所述步骤102包括：步骤F。
在步骤F中，PDCP层通知结果为阻塞的小区组对应的媒体接入控制层，上行待传数据量为0。
本实施例中，用户设备中的PDCP层通知MAC层上行待传数据量为0，同样实现了屏蔽新数据的传输。步骤F可以与步骤E结合，或者说步骤F是步骤E的一种具体实施方式。PDCP层根据阻塞的检测结果，决定屏蔽新数据的传输，此时PDCP层可以通知MAC层，也可以不通知MAC层。当需要通知MAC层时，通知MAC层上行待传数据量为0。
在一个实施例中，所述方法还包括：步骤G1和步骤G2。
在步骤G1中，启动结果为阻塞的小区组对应的接入等级禁止计时器。
在步骤G2中，在接入等级禁止计时器超时时，对所述结果为阻塞的小区组，再次进行接 入等级禁止检测。
本实施例中针对阻塞的小区组，启动相应的接入等级禁止计时器，在接入等级禁止计时器超时前，如果有新数据需要传输，不再进行接入等级禁止检测，沿用之前的检测结果，即检测结果为阻塞，屏蔽新数据的传输。在接入等级禁止计时器超时时，再次进行接入等级禁止检测。这样，可以减少频繁的进行接入等级禁止检测，节省设备功耗。接入等级禁止计时器可以是毫秒级(如20ms-100ms)或秒级(如3-5秒)。
如果辅小区组应用主小区组的检测结果，那么辅小区组可以应用主小区组的接入等级禁止计时器。一个接入等级禁止计时器可以对主小区组和辅小区组同时有效。当然，主小区组和辅小区组也可以有各自的接入等级禁止计时器。
再次进行接入等级禁止检测的结果为阻塞时，重新启动接入等级禁止计时器。
在一个实施例中，所述方法还包括：步骤H。
在步骤H中，在存在接入等级禁止检测的结果不为阻塞的小区组时，将对应结果为阻塞的小区组的所述新数据，在结果不为阻塞的小区组上传输。
本实施例中，对应结果为阻塞的小区组的所述新数据可以屏蔽本次传输。还可以另一种实现方式，即，在存在接入等级禁止检测的结果不为阻塞的小区组时，将对应结果为阻塞的小区组的所述新数据，在结果不为阻塞的小区组上传输。本实施例利用不阻塞的小区组传输更多的数据，来缓解阻塞的小区组。同时保证了新数据的及时上传。
本实施例适用于主小区组和辅小区组分别检测的情况。辅小区组应用辅小区组的检测结果，而不是应用主小区组的检测结果。
在一个实施例中，所述方法还包括：步骤I1-步骤I3。
在步骤I1中，在存在接入等级禁止检测的结果不为阻塞的小区组时，在该小区组上传输新数据。
在步骤I2中，启动活动计时器。
在步骤I3中，在活动计时器超时前，再次需要在已有的会话上传输新数据时，屏蔽接入等级禁止检测。
本实施例中，在存在接入等级禁止检测的结果不为阻塞的小区组时，在该小区组上传输该小区组对应的新数据，还可以传输阻塞的小区组对应的新数据。
启动不阻塞的小区组对应的活动计时器，在活动计时器超时前，再次需要在已有的会话上传输新数据时，屏蔽接入等级禁止检测，直接上传新数据。可以减少频繁的进行接入等级禁止检测，节省设备功耗。在活动计时器超时时，以及再次需要在已有的会话上传输新数据时，需要再次进行接入等级禁止检测。活动计时器可以是毫秒级(如20ms-100ms)或秒级(如3-5秒)。
在活动计时器超时时，以及再次需要在已有的会话上传输新数据时，需要再次进行接入等级禁止检测。再次进行接入等级禁止检测结果为不阻塞时，再次启动活动计时器。
或者，在活动计时器超时前，再次需要在已有的会话上传输新数据时，活动计时器清零。
本实施例适用于主小区组和辅小区组分别检测的情况。辅小区组应用辅小区组的检测结果，而不是应用主小区组的检测结果。
