具体实施方式
在对本发明实施例的复制数据传输功能控制方法进行详细说明之前，首先对双连接架构的协议栈架构进行说明。图1a为双连接系统的下行协议栈架构示意图；图1b为双连接系统的上行协议栈架构示意图；对于下行来说，如图1a所示，分组数据汇聚协议(PDCP，Packet Data Convergence Protocol)实体位于某一个小区群(CG)内，则该CG称为锚点CG(anchor CG)。PDCP实体将PDCP协议数据单元(PDU，Protocol Data Unit)复制为相同的两份，比如一份是PDCP PDU，另一份是复本(Duplicated)PDCP PDU，PDCP PDU和Duplicated PDCP PDU经过不同的CG(例如MCG和SCG)的RLC和MAC，再经过空口到达终端相应的MAC实体、RLC实体，最后再汇聚到终端的PDCP实体，PDCP实体监测到两个PDCP PDU为相 同的复制版本，即丢弃其中一个，将另一个传送至高层实体。相反的，如图1b所示，终端的PDCP实体将PDCP PDU复制为相同的两份，比如一份是PDCP PDU，另一份是Duplicated PDCP PDU，PDCP PDU和Duplicated PDCP PDU经过对应于不同CG(例如MCG和SCG)的RLC和MAC，再经过空口分别到达MCG和SCG的MAC实体、RLC实体，最后再汇聚作为锚点CG的PDCP实体。
如图1a和图1b所示，将PDCP实体分别连接两个RLC和MAC的这一个承载称为split bearer，如果PDCP实体位于MCG，则该承载可称为MCG Split Bearer，如果PDCP实体位于SCG，则该承载可称为SCG Split Bearer。
在5G系统中，对于配置了复制数据传输功能的承载，可通过MAC CE动态激活(activate)或去激活(de-activate)某个承载的复制数据传输功能。对于双连接的场景，MCG和SCG可分别发送MAC CE激活或去激活终端某个split bearer的复制数据传输功能。其中，MAC CE可包含一个比特图，即不同的比特位对应不同的承载。比特位的值表征对应的承载的复制数据传输功能的激活或去激活。但在双连接场景下，终端无法确定MCG或SCG的比特图与承载的对应关系，基于此，提出本发明以下各实施例。
下面结合附图及具体实施例对本发明作进一步详细的说明。

本实施例中，所述终端根据对应于DRB配置的指示信息和/或预设规则确定接收的比特图中的比特位之前，所述方法还包括：所述终端获得网络设备发送的信令，基于所述信令确定对应于DRB的指示信息和/或预设规则。其中，所述信令具体可以为无线资源控制(RRC，Radio Resource Control)信令，即终端可基于网络设备的半静态配置获得指示信息和/或预设规则。
本发明实施例可应用于两种场景，作为第一种应用场景，所述DRB为分裂DRB，所述分裂DRB为配置了复制数据传输功能的分裂DRB。作为第二种应用场景，所述DRB为非分裂DRB，所述非分裂DRB为配置了复制数据传输功能的非分裂DRB。
在第一种应用场景下，作为第一种实施方式，所述指示信息包括指示 标识和指示位；则所述终端根据对应于DRB配置的指示信息确定接收的比特图中的比特位，包括：所述终端基于所述指示标识为所述DRB选择对应于MCG或SCG接收的比特图；所述终端基于所述指示位确定所述比特图中的比特位。
这里，所述指示标识表征确定选择两个比特图中的其中之一的选定规则，即所述指示标识用于指示终端选择对应于MCG的比特图或是对应于SCG的比特图。实际应用中，所述指示标识可以为0/1标识，0和1分别对应于MCG和SCG，例如，当所述指示标识配置为0标识时，选择对应于MCG的比特图，当所述指示标识配置为1时，选择对应于SCG的比特图。当然，也可相反，0标识对应于MCG，1标识对应于SCG，本实施例中不对此进行限定。
所述指示位可以指示比特图中的任一比特位；在比特图包括8个比特位时，则所述指示位可以包括3比特，比如000对应比特图中的第一位，001对应比特图中的第二位，以此类推。则终端基于所述指示位确定所述比特图中的比特位，基于所述比特位的值确定DRB的复制数据传输功能激活/去激活。
作为第二种实施方式，所述指示信息包括指示标识；则所述终端根据对应于DRB配置的指示信息和预设规则确定接收的比特图中的比特位，包括：所述终端基于所述指示标识为所述DRB选择对应于MCG或SCG接收的比特图；所述终端基于所述DRB的标识确定所述比特图中的比特位。
参照第一种实施方式中指示标识的描述，所述指示标识表征确定选择两个比特图中的其中之一的选定规则，即所述指示标识用于指示终端选择对应于MCG的比特图或是对应于SCG的比特图。
作为一种实施方式，所述终端基于所述DRB的标识确定所述比特图中的比特位，包括：所述终端将所述DRB的标识与其他DRB对应的标识进 行排序，按照所述DRB的标识在排序中的位置确定所述比特图中的比特位；其中，所述排序包括升序排序或降序排序。
其中，所述DRB的标识具体为DRB ID，每个DRB的DRB ID均是固定的，且互相不重复。则终端将所有的DRB ID进行排序，排序规则可按照升序排序或降序排序。例如，DRB ID为3，其他DRB的ID包括1、5、7、9，则该DRB ID在所有DRB ID的升序排序中处于第二位，相应的，确定比特图中的第二位比特；而该DRB ID在所有DRB ID的降序排序中处于第三位，相应的，确定比特图中的第三位比特。
作为另一种实施方式，终端也可基于DRB的标识确定比特图中的比特位，本实施方式应用于比特图中的比特位数量大于等于终端的DRB数量且DRB ID不大于8的场景。例如，DRB ID为3，则可确定比特图中的第三位比特。
在第二种应用场景下，作为第一种实施方式，所述指示信息包括指示位；则所述终端根据对应于DRB配置的指示信息确定接收的比特图中的比特位，包括：所述终端为所述DRB选择对应于MCG或SCG接收的比特图；所述终端基于所述指示位确定所述比特图中的比特位。
本应用场景中，终端无需通过指示标识选择对应于MCG或SCG接收的比特图，而是直接可为所述DRB选择对应于MCG或SCG接收的比特图。进一步地，所述指示位可以指示比特图中的任一比特位；在比特图包括8个比特位时，则所述指示位可以包括3比特，比如000对应比特图中的第一位，001对应比特图中的第二位，以此类推。则终端基于所述指示位确定所述比特图中的比特位，基于所述比特位的值确定DRB的复制数据传输功能激活/去激活。
作为第二种实施方式，所述终端根据预设规则确定接收的比特图中的比特位，包括：所述终端为所述DRB选择对应于MCG或SCG接收的比特 图；所述终端基于所述DRB的标识确定所述比特图中的比特位。
本应用场景中，终端无需通过指示标识选择对应于MCG或SCG接收的比特图，而是直接可为所述DRB选择对应于MCG或SCG接收的比特图。
本实施例中，所述终端基于所述DRB的标识确定所述比特图中的比特位，包括：所述终端将所述DRB的标识与其他DRB对应的标识进行排序，按照所述DRB的标识在排序中的位置确定所述比特图中的比特位；其中，所述排序包括升序排序或降序排序。
其中，所述DRB的标识具体为DRB ID，每个DRB的DRB ID均是固定的，且互相不重复。则终端将所有的DRB ID进行排序，排序规则可按照升序排序或降序排序。例如，DRB ID为3，其他DRB的ID包括1、5、7、9，则该DRB ID在所有DRB ID的升序排序中处于第二位，相应的，确定比特图中的第二位比特；而该DRB ID在所有DRB ID的降序排序中处于第三位，相应的，确定比特图中的第三位比特。
作为另一种实施方式，终端也可基于DRB的标识确定比特图中的比特位，本实施方式应用于比特图中的比特位数量大于等于终端的DRB数量且DRB ID不大于8的场景。例如，DRB ID为3，则可确定比特图中的第三位比特。
本应用场景中，对应于不同小区群的非分裂DRB配置的指示信息中的指示位相同或不同，例如，属于不同CG的non-split bearer，对应的指示信息中的指示位可都配置为000。
本实施例中，所述指示标识仅配置于具有复制数据传输功能的分裂DRB对应的指示信息中，表示分裂DRB是由MCG MAC CE控制或是由SCG MAC CE控制。对于非分裂DRB，对应的指示信息中不配置指示标识。
本实施例中，对于non-split bearer，无论对于MCG或是SCG的non-split bearer，其复制数据传输功能只基于对应于MCG的MAC实体接收的MAC  CE或是对应于SCG的MAC实体接收的MAC CE控制。
采用本发明实施例的技术方案，通过对应于DRB配置的指示信息和/或预设规则确定比特图中的比特位，在双连接场景下可根据指示信息确定对应于MCG或SCG的比特图，从而能够基于比特图中比特位的指示实现DRB的复制数据传输功能的激活/去激活。
下面结合具体的应用场景对本发明实施例的复制数据传输功能控制方法进行详细说明。
场景一
本场景中，终端基于网络设备的信令确定DRB的指示标识和指示位，基于该指示标识确定为DRB选择对应于MCG接收的MCG MAC CE。
终端从MCG MAC实体接收到用于控制复制数据传输功能激活/去激活的MAC CE。
终端先确定哪些DRB由MCG MAC实体控制，比如如图3所示，可以先确定DRB ID＝1的non-split DRB由MCG MAC CE控制，同时通过查看split DRB中配置的0/1指示标识确定DRB ID＝3的split DRB由MCG MACCE控制。
终端再查看这两个DRB中的指示位，确定DRB ID＝1的non-split DRB由比特图中的第一位控制，DRB ID＝3由比特图中的第二位控制，比特图中的其余比特位均为无效位。
终端的MAC实体将比特图中第一位的bit值指示给DRB ID＝1的non-split DRB的PDCP实体，终端的MAC实体将比特图中第二位的bit值指示给DRB ID＝3的split DRB的PDCP实体；相应的PDCP实体根据指示的bit值决定相应的DRB的复制数据传输功能激活/去激活。
场景二
本场景中，终端基于网络设备的信令确定DRB的指示标识，基于该指 示标识确定为split DRB选择对应于MCG接收的MCG MAC CE。
终端从MCG MAC实体接收到用于控制复制数据传输功能激活/去激活的MAC CE。
终端先确定哪些DRB由MCG MAC实体控制，比如如图3所示，可以先确定DRB ID＝1的non-split DRB由MCG MAC CE控制，同时通过查看split DRB中配置的0/1指示标识确定DRB ID＝3的split DRB由MCG MAC CE控制。
终端根据这些DRB的ID决定对应关系，比如可以通过DRB ID的升序(或者降序)来决定对应关系。例如，终端中的DRB ID包括1、3、5、6，DRB ID＝1在升序排序中位于第一位，则DRB ID＝1的non-split DRB对应于比特图中的第一位，DRB ID＝3在升序排序中位于第二位，则DRB ID＝3的split DRB对应于比特图中的第二位，比特图中的其余比特位均为无效位。
终端MAC实体将比特图中第一位的bit值指示给DRB ID＝1的non-split DRB的PDCP实体，终端把MAC实体将比特图中第二位的bit值指示给DRB ID＝3的split DRB的PDCP实体；相应的PDCP实体根据指示的bit值决定相应的DRB的复制数据传输功能激活/去激活。
