具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本公开进行详细描述。
在进行本公开实施例的说明时，首先对下面描述中所用到的一些概念进行解释说明。
1、包数据汇聚协议(Packet Data Convergence Protocol，PDCP)数据复制(即PDCP duplication)发送介绍
新空口(New Radio，NR)中，为提高数据传输的可靠性，引入了PDCP duplication功能。网络侧配置用户设备(User Equipment，UE，也称终端)的无线承载(Radio Bearer，RB)对应的PDCP层是否要将PDCP实体的数据复制后，将复制的数据分别通过两个不同的路径(如两个不同的无线链路控制 (Radio Link Control，RLC)实体)进行发送，不同RLC实体对应不同的逻辑信道。
PDCP数据复制功能可以通过媒体接入控制层控制信令(Medium Access Control Control Element，MAC CE)指示是否启动(即激活)还是停止(即去激活)。网络侧在配置该RB的PDCP复制数据功能的时候，可以配置该功能是否在配置后立即开启，即不需要MAC CE信令再额外激活。
2、PDCP数据复制功能的承载类型
在5G***中由于采用了双连接(Dual Connectivity，DC)架构(包括两个小区组，即主小区组(Master Cell Group，MCG)和辅小区组(Secondary Cell Group，SCG))，PDCP数据复制功能的承载类型包括图1和图2所示的两种：
A11、分离承载(Split bearer)：该承载对应的PDCP实体在1个小区组，对应的2个(或多个)RLC和2个(或多个)MAC在不同的小区组。
A12、复制承载(Duplicate bearer)：该承载对应1个PDCP实体，2个(或多个)RLC实体和1个MAC实体在1个小区组。
其中，MCG对应的MCG MAC实体，SCG对应SCG MAC。
其中，MCG对应的网络实体为主节点(Main Node，MN)，SCG对应的网络实体为辅节点(Secondary Node，SN)。
3、多路径PDCP数据复制(Multiple Leg PDCP Duplication)
如图3和图4所示，PDCP数据复制功能可以配置超过两个(如，3个)发送路径(如，1个PDCP实体对应3个以上的RLC实体)，则网络侧可能会选择去激活其中1个或多个路径(如，可以去激活1个路径，但是仍然有2个路径可以工作。去激活的路径不用于数据的接收或发送)，而该PDCP数据复制功能仍然可以继续通过激活的路径使用。对于去激活的路径，终端不能通过该逻辑信道发送数据；对于激活的路径，终端可以通过该逻辑信道发送数据。
本公开所要解决的技术问题是，当某RB对应的传输路径被去激活时，为提高资源利用率，PDCP会指示去激活的传输路径对应的RLC实体丢弃从上层接收的复制数据包，但是在该RB配置了大于两条传输路径的PDCP数据复制功能的情况下，如果被丢弃的数据在当前激活的传输路径中没有副本， 就会导致丢包。
本公开上述问题，提供一种数据处理方法、信息配置方法、终端及网络设备。
如图5所示，本公开实施例提供一种数据处理方法，应用于终端，包括：
步骤501，终端的包数据汇聚协议PDCP实体确定当前处于激活状态的传输路径集合中，需要由激活状态变为去激活状态的至少一条第一传输路径；
需要说明的是，该传输路径集合中包括至少一条传输路径。
步骤502，在所述至少一条第一传输路径不是所述传输路径集合中所有传输路径时，终端的PDCP实体指示所述第一传输路径对应的无线链路控制RLC实体丢弃复制数据。
例如，该复制数据为PDCP数据协议数据单元(Protocol Data Unit，PDU)。
需要说明的是，本公开实施例应用于在第一无线承载(RB)的包数据汇聚协议(PDCP)数据复制功能对应至少三条传输路径的情况下，该第一RB指的是终端的某一条RB。
需要说明的是，本公开实施例中，若当前处于激活状态的传输路径没有全部被配置去激活，则PDCP实体只指示被配置去激活的传输路径对应的RLC实体丢弃复制数据；若当前处于激活状态的传输路径全部被配置去激活，则PDCP实体不指示被配置去激活的传输路径对应的RLC实体丢弃复制数据；需要说明的是，该复制数据由RLC实体从上层接收得到，以此可以避免在激活的路径全部去激活的情况下，易造成丢包的情况。
需要说明的是，假设终端的PDCP实体指示RLC实体丢弃复制数据时，会向RLC实体发送丢弃指示，则终端的PDCP实体不指示RLC实体丢弃复制数据，指的是，终端的PDCP实体不向RLC实体发送丢弃指示。
例如，终端的某一个RB的PDCP数据复制功能对应有六条传输路径，分别为传输路径1、传输路径2、传输路径3、传输路径4、传输路径5和传输路径6，在前一个时刻，传输路径1、传输路径2、传输路径3、传输路径4均处于激活状态，下一个时刻，终端获知网络设备将传输路径1、传输路径2和传输路径3配置为去激活，则在此种情况下，PDCP实体指示传输路径1、传输路径2和传输路径3对应的RLC实体丢弃复制数据；若传输路径1、传 输路径2、传输路径3和传输路径4均被配置为去激活，传输路径5和传输路径6配置为激活，则PDCP实体不指示传输路径1、传输路径2、传输路径3和传输路径4对应的RLC实体丢弃复制数据。
进一步，还需要说明的是，在所述步骤501之前，该数据处理方法还包括：
获取终端的第一无线承载RB的PDCP数据复制功能的配置信息。
需要说明的是，下面分别从是否为PDCP数据复制功能配置主传输路径的角度对本公开实施例进行具体说明如下。
一、不配置主传输路径
在此种情况下，该配置信息包括：第一RB的PDCP数据复制功能的初始状态；具体地，所述初始状态包括：激活状态或去激活状态。
需要说明的是，该初始状态通过传输路径集合指示；例如，当该传输路径集合只指示了一条传输路径时，表示去激活该第一RB对应的PDCP数据复制功能，该RB对应的数据通过所指示的传输路径传输；当该传输路径集合指示了至少两条传输路径时表示激活该RB对应的PDCP数据复制功能，该第一RB对应的数据通过所指示的传输路径传输。
具体地，在此种情况下，步骤501的实现方式为：
终端的PDCP实体获取指示信息，所述指示信息用于指示需要去激活的传输路径；根据所述指示信息，终端的PDCP实体确定当前处于激活状态的传输路径集合中，需要由激活状态变为去激活状态的至少一条第一传输路径。
需要说明的是，该指示信息可以具体通过如下方式中的一项获取得到：
A11、终端的PDCP实体接收网络设备通过预设信令发送的指示信息；
其中，所述预设信令包括：媒体接入控制(Medium Access Control，MAC)信令或无线资源控制(Radio Resource Control，RRC)信令。
A12、终端的PDCP实体获取终端的高层发送的指示信息；
如，终端的高层基于网络设备的配置或协议约定的条件判断是否去激活某RB对应的传输路径，并发送指示信息给终端的PDCP实体。
还需要说明的是，该指示信息还可以用于指示激活的传输路径，因本公开实施例中只考虑由激活状态变为去激活状态的传输路径，因此，对于由去 激活状态变为激活状态的传输路径，本公开实施例中不关注。
还需要说明的是，当所述至少一条第一传输路径是所述传输路径集合中所有传输路径时，PDCP实体不指示第一传输路径对应的RLC实体丢弃复制数据，终端的MAC实体传输所述第一传输路径对应的RLC实体中的复制数据。
具体地，当由激活状态变为去激活状态的传输路径对应的RLC实体还有数据时，该RLC实体对应的MAC继续为其分配上行授权，MAC实体按照预设规则，传输所述第一传输路径对应的RLC实体中的复制数据；
具体地，所述预设规则包括：
所述第一传输路径对应的RLC实体对应的逻辑信道限制是为PDCP数据复制功能配置的，当传输所述第一传输路径对应的RLC实体中的数据时，所述第一传输路径对应的RLC实体对应的逻辑信道不应用逻辑信道限制。
也就是说，如果该RLC实体对应的逻辑信道限制是因为PDCP数据复制功能而配置的，那么当MAC传输被去激活的传输路径对应的RLC实体中的数据时，对该RLC实体对应的逻辑信道不应用逻辑信道限制(如逻辑信道与载波映射限制，或逻辑信道与频域范围(如带宽部分(Band Width Part，BWP))映射限制)，否则，该RLC实体对应的逻辑信道应用逻辑信道限制。
二、配置主传输路径
在此种情况下，该配置信息可以采用以下两种方式中的任一种：
方式一、该配置信息包括：第一RB的主传输路径；
需要说明的是，主传输路径始终处于激活状态。
方式二、该配置信息包括：第一RB的主传输路径和所述第一RB的PDCP数据复制功能的初始状态；
具体地，所述初始状态包括：激活状态或去激活状态。
可选地，该初始状态通过以下方式中的至少一项指示：
B11、预设比特个数的指示信息；
例如，可以用1比特的指示信息，例如，当该指示变量取值为“0”时，表示去激活该RB对应的PDCP数据复制功能，该RB对应的数据通过主传输路径传输，当该指示变量取值为“1”时，表示激活该RB对应的PDCP数据复制 功能，该RB对应的数据通过所有配置的传输路径传输。
B12、传输路径集合；
例如，当该传输路径集合指示的除主传输路径外无其他传输路径时，表示去激活该RB对应的PDCP数据复制功能，当该传输路径集合指示的除主传输路径外包含至少一条传输路径时表示激活该RB对应的PDCP数据复制功能。
还需要说明的是，当初始状态通过预设比特个数的指示信息和传输路径集合一同指示时，当初始状态指示为激活PDCP数据复制功能时，传输路径集合指示激活的传输路径集合。
具体地，在此种情况下，步骤501的实现方式为：
接收网络设备发送的重配置主传输路径的无线资源控制RRC信令；
根据RRC信令，终端的PDCP实体确定当前处于激活状态的传输路径集合中，需要由激活状态变为去激活状态的至少一条第一传输路径；
其中，所述RRC信令中携带主传输路径重配置后的PDCP数据复制功能的初始状态。
需要说明的是，终端可以由重配置后的PDCP数据复制功能的初始状态确定哪些传输路径由激活状态变为去激活状态。
还需要说明的是，当所述至少一条第一传输路径是所述传输路径集合中所有传输路径时，PDCP实体不指示第一传输路径对应的RLC实体丢弃复制数据，终端的MAC实体传输所述第一传输路径对应的RLC实体中的复制数据。
具体地，当由激活状态变为去激活状态的传输路径对应的RLC实体还有数据时，该RLC实体对应的MAC继续为其分配上行授权，MAC实体按照预设规则，传输所述第一传输路径对应的RLC实体中的复制数据；
具体地，所述预设规则包括：
所述第一传输路径对应的RLC实体对应的逻辑信道限制是为PDCP数据复制功能配置的，当传输所述第一传输路径对应的RLC实体中的数据时，所述第一传输路径对应的RLC实体对应的逻辑信道不应用逻辑信道限制。
也就是说，如果该RLC实体对应的逻辑信道限制是因为PDCP数据复制 功能而配置的，那么当MAC传输被去激活的传输路径对应的RLC实体中的数据时，对该RLC实体对应的逻辑信道不应用逻辑信道限制(如逻辑信道与载波映射限制，或逻辑信道与频域范围(如BWP)映射限制)，否则，该RLC实体对应的逻辑信道应用逻辑信道限制。
具体地，还需要说明的是，当配置了主传输路径后，终端的PDCP实体的行为还可以包括：根据去激活的传输路径的指示信息，确定由激活状态变为去激活状态的第二传输路径，PDCP实体指示第二传输路径对应的RLC实体丢弃复制数据。
具体地，该去激活的传输路径的指示信息可以由网络设备下发的MAC信令指示；也可以由终端高层的信令指示，如终端的高层基于网络设备的配置或协议约定的条件判断是否激活去激活某RB对应的传输路径，并发送指示信息给终端的PDCP实体。
需要说明的是，本公开实施例，终端的PDCP实体通过确定当前处于激活状态的传输路径集合中，需要由激活状态变为去激活状态的至少一条第一传输路径；在所述至少一条第一传输路径不是所述传输路径集合中所有传输路径时，终端的PDCP实体指示所述第一传输路径对应的RLC实体丢弃复制数据，由于丢弃的数据在当前处于激活状态的传输路径中存在副本，以此可避免丢包，可以保证通信可靠性。
如图6所示，本公开实施例还提供一种信息配置方法，应用于网络设备，包括：
步骤601，发送第一无线承载RB的包数据汇聚协议PDCP数据复制功能的配置信息给终端；
其中，PDCP数据复制功能对应至少三条传输路径。

所述初始状态包括：激活状态或去激活状态。
可选地，所述初始状态通过传输路径集合指示。

所述配置信息包括：第一RB的主传输路径和所述第一RB的PDCP数据 复制功能的初始状态；
所述初始状态包括：激活状态或去激活状态。
可选地，所述初始状态通过以下方式中的至少一项指示：
预设比特个数的指示信息；
传输路径集合。
需要说明的是，上述实施例中所有关于网络设备的描述均适用于该信息配置方法的实施例中，也能达到与之相同的技术效果。

确定模块701，用于确定当前处于激活状态的传输路径集合中，需要由激活状态变为去激活状态的至少一条第一传输路径；
指示模块702，用于在所述至少一条第一传输路径不是所述传输路径集合中所有传输路径时，指示所述第一传输路径对应的无线链路控制RLC实体丢弃复制数据；
