Description

数据复制下的处理方法及相关设备 技术领域
本申请涉及通信技术领域，具体涉及一种数据复制下的处理方法及相关设备。
背景技术
在双连接(Dual connectivity，DC)下，复制数据传输方式采用的是分叉承载(split bearer)的协议架构，对于上下行来说，分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层位于某一个小区(Cell Group，CG)，如主小区(Master Cell Group，MCG)或者辅小区(Secondary Cell Group，SCG)，PDCP所在的CG为锚点小区(anchor CG)。发送端设备的PDCP层将PDCP协议数据单元(Protocol Data Unit，PDU)复制为相同的两个PDU，比如一个是PDCP PDU，一个是Duplicated PDCP PDU，两个PDCP PDU经过不同CG的无线链路层控制协议(Radio Link Control，RLC)层和媒体访问控制(Media Access control，MAC)层，在经过空口到达接收端设备相应的MAC层和RLC层，最后再汇聚到接收端设备的PDCP层。在接收端设备的PDCP层监测到两个PDCP PDU为相同的PDU的情况下，接收端设备的PDCP层会丢弃其中一个PDU，将另外一个PDU递交到高层。

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。
图1A示出了本申请涉及的无线通信系统。所述无线通信系统不限于长期演进(Long Term Evolution，LTE)系统，还可以是未来演进的第五代移动通信(the 5th Generation，5G)系统、新空口(NR)系统，机器与机器通信(Machine to Machine，M2M)系统等。如图1A所示，无线通信系统100可包括：一个或多个网络设备101和一个或多个用户设备102。其中：
网络设备101可以为基站，基站可以用于与一个或多个用户设备进行通信，也可以用于与一个或多个具有部分用户设备功能的基站进行通信(比如宏基站与微基站，如接入点，之间的通信)。基站可以是时分同步码分多址(Time Division Synchronous Code Division Multiple Access，TD-SCDMA)系统中的基站收发台(Base Transceiver Station，BTS)，也可以是LTE系统中的演进型基站(Evolutional Node B，eNB)，以及5G系统、新空口(NR)系统中的基站。另外，基站也可以为接入点(Access Point，AP)、传输节点(Trans TRP)、中心单元(Central Unit，CU)或其他网络实体，并且可以包括以上网络实体的功能中的一些或所有功能。
用户设备102可以分布在整个无线通信系统100中，可以是静止的，也可以是移动的。在本申请的一些实施例中，终端102可以是移动设备、移动台(mobile station)、移动单元(mobile unit)、M2M终端、无线单元，远程单元、用户代理、移动客户端等等。
具体的，网络设备101可用于在网络设备控制器(未示出)的控制下，通过无线接口103与用户设备102通信。在一些实施例中，所述网络设备控制器 可以是核心网的一部分，也可以集成到网络设备101中。网络设备101与网络设备101之间也可以通过回程(blackhaul)接口104(如X2接口)，直接地或者间接地，相互通信。
图1B示出了双连接的网络构架示意图。如图1B所示，网络设备1011提供基本的网络覆盖105。网络设备1012提供相对较小的网络覆盖106。处于网络设备1011和网络设备1012的共同覆盖范围内的用户设备102(UserEquipment，UE)将能够同时与网络设备1011和网络设备1012建立通信连接。此处，将一个用户设备102与一个网络设备1011和网络设备1012之间同时具有相连的情况称之为双连接。图1B所示，在双连接下，网络设备1011为主网络设备(master node，MN)，网络设备1012为辅网络设备(slave node，SN)。
图1C示出了在DC下上行数据复制传输的示意图。如图1C所示，用户设备(UE)至少包括一个PDCP实体、两个RLC实体和两个MAC实体。在数据复制下，用户设备的PDCP实体进行数据复制，以得到PDCP PDU和复制PDCP PDU，然后用户设备的PDCP实体PDCP PDU和复制PDCP PDU分别递交给用户设备的两个RLC实体，用户设备的两个RLC实体再分别递交给用户设备的两个MAC实体，用户设备的两个MAC实体再通过无线接口将两个数据传输给两个网络设备，最后在其中一个网络设备的PDCP实体进行聚合。
图1D示出了在DC下下行数据复制传输的示意图。如图1D所示，处于小区1(cell group，CG1)的网络设备至少包括一个PDCP实体、一个RLC实体和一个MAC实体，处于CG2的网络设备至少包括一个RLC实体和一个MAC实体。在数据复制下，处于CG1的网络设备的PDCP实体进行数据复制，以得到PDCP PDU和复制PDCP PDU，然后处于CG1的网络设备的PDCP实体将PDCP PDU和复制PDCP PDU分别递交给自己的RLC实体和处于CG1的网络设备的RLC实体，这两个网络设备的RLC实体再分别将这两个数据分别递交给自己的MAC实体，这两个网络设备的MAC实体再将这两个数据通过无线接口传输给用户设备，最后在用户设备的PDCP实体进行聚合。
在NR现有的讨论中，对于配置了复制数据传输功能的无线承载，可以通 过MAC控制元素(Control Element，CE)动态的激活(activate)或者去激活(Deactivate)某一个承载的数据复制传输功能。在DC场景下，由于主节点(master node，MN)和辅节点(slave node，SN)均可发送MAC CE来激活或者去激活用户设备某一个split bearer的复制数据功能，该种情况下，为了避免两个网络节点均发送MAC CE控制用户设备的数据复制传输功能，两个网络节点之间需要协调，以确保只要一个网络节点对用户设备进行数据复制控制。
本申请中，首先，在DC下，事先配置一个与默认路径相关的数据复制控制规则，该数据复制控制规则可以是协议配置的，也可以是网络设备配置。如果该数据复制控制规则是协议配置的，两个网络设备和用户设备都知道；或者两个网络设备知道，用户设备不知道。如果该数据复制控制规则是其中一个网络设备配置的，该配置的这个网络设备可将该数据复制控制规则发送给另一个网络设备和用户设备；或者只发送给另一个网络设备。
然后，第二网络设备先将一个默认路径配置信息发送给第一网络设备和用户设备。对于第二网络设备来说，第二网络设备自己是知道自己是否要通过MAC CE控制用户设备的数据复制的。第二网络设备之所以向第一网络设备发送默认路径配置信息是为了让第一网络设备知道第一网络设备是否要通过MAC CE控制用户设备的数据复制。第二网络设备之所以向用户设备发送默认路径配置信息是为了让用户设备知道默认路径是哪个(以使得后续用户设备去激活数据复制时，在默认路径上发送数据)，和/或让用户设备知道是哪个网络设备控制自己的数据复制传输功能。
可见，在本申请中第二网络设备通过向第一网络设备发送默认路径配置信息，以达到确保只要一个网络设备对用户设备进行数据复制控制的目的。另外，第二网络设备向用户设备发送默认路径配置信息，以达到后续用户设备在去激活数据复制的情况下明确在哪个路径上发送数据的目的。另外，在用户设备知道数据复制控制规则的情况下，第二网络设备向用户设备发送默认路径配置信息，以到达用户设备明确是哪个网络设备对用户设备进行数据复制控制的目的。
需要说明的，图1A示出的无线通信系统100仅仅是为了更加清楚的说明 本申请的技术方案，并不构成对本申请的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请提供的技术方案对于类似的技术问题，同样适用。

步骤c8：在用户设备去激活数据复制的情况下，用户设备向默认路径发送数据。
步骤c9：在用户设备激活数据复制的情况下，用户设备向第一网络设备所在的路径和第二网络设备所在的路径发送数据。
下面针对图4A-图4C所示的实施例进行详细的说明。
其中，在DC下，第一网络设备是MN，第二网络设备是SN，或者，第一网络设备是SN，第二网络设备是MN。
其中，在DC下，路径包括主小区(Master cell group，MCG)路径和辅小区(slave cell group，SCG)路径，主小区路径即MN所在的路径，辅小区 路径即SN所在的路径。
其中，默认路径配置信息是第二网络设备配置的。当默认路径配置信息是关于MCG路径配置信息时，表示默认路径为MCG路径，当默认路径配置信息是关于SCG路径配置信息时，表示默认路径为SCG路径。
其中，第一网络设备基于路径配置信息确定是否通过MAC CE控制用户设备的数据复制的具体实现方式有：第一网络设备基于所述路径配置信息和上述数据复制控制规则确定是否通过MAC CE控制用户设备的数据复制。
进一步地，上述数据复制控制规则有：在默认路径为第一网络设备所在的路径的情况下，所述第一网络设备不通过MAC CE控制用户设备的数据复制；在默认路径为第二网络设备所在的路径的情况下，第一网络设备通过MAC CE控制所述用户设备的数据复制。
需要说明的是，第二网络设备基于路径配置信息确定是否通过MAC CE控制用户设备的数据复制的具体实现方式与第一网络设备相同，在此不在叙述。
其中，在两个网络设备均向用户设备发送MAC CE的情况下，这两个设备可以是在同一时刻向用户设备发送的，也可以是在不同时刻向用户设备发送的，在此不作限定。
其中，用户设备基于一个用于激活或去激活的MAC CE来激活或去激活数据复制，很容易理解，比如用户设备接收到的MAC CE是Deactivation，那么用户设备去激活数据，又比如用户设备接收到的MAC CE是activation，那么用户设备激活数据。
在本申请的一实施例中，用户设备基于根据第一MAC CE或第三MAC CE激活或去激活数据复制的具体实现方式有：
在默认路径为第一网络设备所处的路径的情况下，用户设备基于第三MAC CE激活或去激活数据复制；
在默认路径为第二网络设备所处的路径的情况下，用户设备基于第一MAC CE激活或去激活数据复制。
具体的，基于上述数据复制控制规则可知道控制用户设备的数据复制的设备是不在默认路径的网络设备，并且用户设备也是知道默认路径配置信息的， 即用户设备(在用户设备也知道上述数据复制控制规则的情况下，)是知道控制自己的数据复制的网络设备不在默认路径上。在两个网络设备均向用户设备发送MAC CE的时候，假如默认路径为第一网络设备所处的路径，用户设备知道是第二网络设备控制自己的数据复制，那么用户设备忽视第一网络设备发送的MAC CE，仅基于第二网络设备发送的MAC CE控制自己的数据复制；又假设默认路径为第二网络设备所处的路径，用户设备知道是第一网络设备控制自己的数据复制，那么用户设备忽视第二网络设备发送的MAC CE，仅基于第一网络设备发送的MAC CE控制自己的数据复制。
在本申请的一实施例中，用户设备基于根据第一MAC CE和第四MAC CE激活或去激活数据复制的具体实现方式有：在第一MAC CE去激活数据复制，第四MAC CE激活数据复制，用户设备激活数据复制。
或者，在本申请的一实施例中，用户设备基于根据第一MAC CE和第四MAC CE激活或去激活数据复制的具体实现方式有：在第一MAC CE去激活数据复制，第四MAC CE激活数据复制，用户设备去激活数据复制。
具体地，在一个MAC CE是激活数据复制，另一个MAC CE是激活数据复制的情况下，用户设备侧基于这两个MAC CE得到的肯定是激活数据复制。在一个MAC CE是去激活数据复制，另一个MAC CE是去激活数据复制的情况下，用户设备侧基于这两个MAC CE得到的肯定是去激活数据复制。由于第四MAC CE中的至少一个比特位被置为设定值，这个设定值可以是0，也可以是1。为了避免第四MAC CE控制用户设备数据复制的情况，协议规定当这两个MAC CE有一个MAC CE是激活数据复制，另一个MAC CE是去激活数据复制时，对应的是激活数据复制；或者协议规定当这两个MAC CE有一个MAC CE是激活数据复制，另一个MAC CE是去激活数据复制时，对应的是去激活数据复制。
举例来说，如图4D所示，图4D示出了本申请实施例提供的一种MAC CE的示意图。如图4D所示，C1-C7表示无线承载所对应的比特位，R表示保留比特位，当某个无线承载对应的比特位为0时，表示去激活，当某个无线承载对应的比特位为1时，表示激活。假设用户设备的无线承载有C7、C6、C5。由于第一网络设备知道是自己要控制用户设备的数据复制传输，因此第一网络设 备发送的第一MAC CE是第一网络设备根据自己实际情况确定的。假设第一MAC CE为10100000，可见C7对应的比特位为1，C6对应的比特位为0，可见C5对应的比特位为1。由于第二网络设备知道是不自己要控制用户设备的数据复制传输，因此第二网络设备发送的第三MAC CE中C7、C6、C5对应的比特位均设置为固定值，假设该固定值为1，那么第二MAC CE为11100000。在用户设备侧，用户设备是不知道哪个MAC CE中包含的比特位的值是固定的，因此用户设备将两个MAC CE进行与操作，进而可得到C7、C6、C5对应的值1、0、1(与第一MAC CE中C7、C6、C5对应的值一样)，可见在该种情况下，还是第一网络设备起到控制用户设备数据复制传输功能的作用。
又假设该固定值为0，那么第二MAC CE为00000000。在用户设备侧，用户设备是不知道哪个MAC CE中包含的比特位的值是固定的，因此用户设备将两个MAC CE进行或操作，进而可得到C7、C6、C5对应的值1、0、1(与第一MAC CE中C7、C6、C5对应的值一样)，可见在该种情况下，还是第一网络设备起到控制用户设备数据复制传输功能的作用。
需要说明的是，用户设备基于根据第二MAC CE和第三MAC CE激活或去激活数据复制与用户设备基于根据第一MAC CE和第四MAC CE激活或去激活数据复制的具体实现原理相同，在此不在叙述。
在本申请的一实施例中，用户设备基于根据第一MAC CE和第六MAC CE激活或去激活数据复制的具体实现方式有：在第一MAC CE去激活数据复制，第四MAC CE激活数据复制，用户设备激活数据复制。
在本申请的一实施例中，第二网络设备向第一网络设备和用户设备发送默认路径配置信息的具体实现方式是：在建立一个数据复制承载的情况下，第二网络设备向第一网络设备和用户设备发送默认路径配置信息。
具体地，先建立一个数据复制承载的情况下，在第一网络设备侧，第一网络设备是不知道自己是否要控制该承载的数据复制传输功能，在用户设备侧，用户设备是不知道默认路径是哪个，和/或不知道是哪个网络设备要控制自己的数据复制传输功能，因此在该情况下，第二网络设备需向第一网络设备和用户设备发送默认路径配置信息，以及时通知第一网络设备和用户设备该承载的具体情况，进而达到及时控制数据复制的目的。
在本申请的一实施例中，第二网络设备向第一网络设备和用户设备发送默认路径配置信息的具体实现方式是：在需要修改一个已经建立的数据复制承载的默认路径的情况下，所述第二网络设备向第一网络设备和用户设备发送默认路径配置信息。
具体地，在修改一个已经建立的数据复制承载的默认路径的情况下，在第一网络设备侧，第一网络设备是不知道自己是否要控制已建立的承载的数据复制传输功能，在用户设备侧，用户设备是不知道已建立的承载的默认路径是哪个，和/或不知道是哪个网络设备要控制自己的数据复制传输功能，因此在该情况下，第二网络设备需向第一网络设备和用户设备发送默认路径配置信息，以及时通知第一网络设备和用户设备已建立的承载的具体情况，进而达到及时控制数据复制的目的。
在本申请的一实施例中，用户设备向默认路径发送数据的具体实施方式有：在所述用户设备待发送的数据小于或等于门限值的情况下，所述用户设备向默认路径发送数据。
进一步地，所述方法还包括：
在所述用户设备待发送的数据大于所述门限值的情况下，所述用户设备在所述第一网络设备所在的路径和所述第二网络设备所在的路径发送数据；其中，在所述第一网络设备所在的路径发送的数据与在所述第二网络设备所在的路径发送的数据不同。
具体的，在数据复制去激活，用户设备待发送的数据小于或等于一个门限值的情况下，此时由于用户设备需要发送的数据较少，仅在一个路径上发送数据即可。在数据复制去激活，用户设备待发送的数据大于门限值的情况下，此时由于用户设备需要发送的数据较多，如果用户设备仅使用一个路径发送数据可能会导致数据传输效率低的问题，该种情况下，为了提高数据传输效率，用户设备使用两个路径发送数据，比如，用户设备待发送的数据有数据1、数据2、数据3、数据4、数据5和数据6，用户设备在第一网络设备所在的路径发送数据1、数据2和数据3，在第二网络设备所在的路径发送数据4、数据5和数据6。
基于上述的解释对上述方法进行举例说明。
第一个例子：假设在DC下，第二网络设备为MN，第一网络设备为SN。首先，MN向SN和用户设备发送默认路径配置信息，假设默认路径配置信息是MCG的配置信息，可知默认路径为第二网络设备所在的路径。第二网络设备知道是第一网络设备通过MAC CE控制用户设备的数据复制，因此第二网络设备不发送MAC CE。第一网络设备在接收到默认路径配置信息之后，第一网络设备基于默认路径配置信息知道是自己通过MAC CE控制用户设备的数据复制，因此第一网络设备向用户设备发送一个用于激活或去激活数据复制的MAC CE。假设该MAC CE是Deactivation，用户设备在接收到该MAC CE之后，去激活数据复制。在用户设备去激活数据复制之后，用户设备向MCG路径发送数据。又假设该MAC CE是activation，用户设备在接收到该MAC CE之后，激活数据复制。在用户设备激活数据复制之后，用户设备向MCG和SCG路径发送数据。
第二个例子：假设在DC下，第二网络设备为MN，第一网络设备为SN。首先，MN向SN和用户设备发送默认路径配置信息，假设默认路径配置信息是MCG的配置信息，可知默认路径为第二网络设备所在的路径。第二网络设备知道是第一网络设备通过MAC CE控制用户设备的数据复制，因此第二网络设备发送一个不用于激活或去激活数据复制的MAC CE(假如MAC CE-1)。第一网络设备在接收到默认路径配置信息之后，第一网络设备基于默认路径配置信息知道是自己通过MAC CE控制用户设备的数据复制，因此第一网络设备向用户设备发送一个用于激活或去激活数据复制的MAC CE(假如MACCE-2)。由于用户设备接收到了MAC CE-1和MAC CE-2，因为用户设备基于默认路径配置信息是第一网络设备控制自己的数据复制，因此用户设备忽视MAC CE-1，仅基于MAC CE-2进行激活或去激活。假设该MAC CE-2是Deactivation，用户设备在接收到该MAC CE之后，去激活数据复制。在用户设备去激活数据复制之后，用户设备向MCG路径发送数据。又假设该MACCE-2是activation。用户设备在接收到该MAC CE之后，激活数据复制。在用户设备激活数据复制之后，用户设备向MCG和SCG路径发送数据。
需要说明的，上述示例仅仅用于解释，不应构成限定。
可见，在本申请中第二网络设备通过向第一网络设备发送默认路径配置信息，以达到确保只要一个网络设备对用户设备进行数据复制控制的目的。另外，第二网络设备向用户设备发送默认路径配置信息，以达到后续用户设备在去激活数据复制的情况下明确在哪个路径上发送数据的目的。另外，在用户设备知道数据复制控制规则的情况下，第二网络设备向用户设备发送默认路径配置信息，以到达用户设备明确是哪个网络设备对用户设备进行数据复制控制的目的。
