相关申请的交叉引用
本申请主张在2019年2月14日在中国提交的中国专利申请号No.201910114970.7的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，更具体地涉及一种数据包承载路径确定、信息发送方法和设备。
背景技术
在无线通信系统中，为了进一步地提高数据传输可靠性和/或降低数据传输时延，终端设备(User Equipment，UE)侧引入了无线承载(Radio Bearer，RB)的分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)数据复制功能。PDCP数据复制功能，是指将PDCP实体的数据进行复制，并将复制的数据分别通过多个(两个或两个以上)不同的路径进行发送的技术，例如，将复制的数据分别通过多个无线链路控制(Radio Link Control，RLC)实体进行发送，其中，不同的RLC实体对应不同的逻辑信道。
PDCP数据复制功能可由网络侧配置。例如，网络侧可以先通过无线资源控制(Radio Resource Control，RRC)消息给UE侧的RB配置该功能，然后通过媒体接入控制层控制信令(Medium Access Control Element，MACCE)指示激活(开启)或去激活(停止)该RB的该功能；或者，网络侧可以在通过RRC消息给UE侧的RB配置该功能的同时，通过该RRC消息配置该功能是否在配置后立即激活，也即不需要再通过MAC CE信令额外激活该功能。
UE侧向网络侧传输的数据包括非复制数据包(如PDCP Control协议数据单元(Protocol Data Unit，PDU))和复制数据包(如PDCP data PDU)。非复制数据包不会被复制，且通过主路径发送，其中，主路径是上文中的多个不同的路径中的一个，主路径一直处于激活状态，不需要通过MAC CE信 令进行激活；复制数据包在对应的RB的PDCP数据复制功能处于激活状态时被复制成多份，并将复制得到的多份数据分别通过上文中的多个不同的路径发送。
然而，对于配置了PDCP数据复制功能的RB而言，如果网络侧将用于非复制数据包传输的路径去激活后，UE究竟采用哪个路径发送非复制数据包尚不清楚；或者，由于复制数据包只能通过网络侧规定的指定路径发送(如网络侧指定数据包1通过路径1发送，数据包2通过路径2发送)，使得复制数据包的发送路径的确定不够灵活。

可选地，可以在用于承载目标RB对应的PDCP非复制数据包的主路径去激活的情况下，执行步骤101。主路径为网络侧预先配置的用于承载目标RB对应的分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)非数据包的路径，主路径可以是所述多个配置路径中的一个路径，且在实施本公开的一些实施例提供的数据包承载路径确定方法时，主路径处于去激活状态。
目标RB可以是特定RB，例如，编号为1的数据无线承载(Data Radio  Bearer，DRB)，具体如DRB1；或者，特定的信令无线承载(Signaling Radio Bearer，SRB)，如SRB1。
SRB用于无线资源控制(Radio Resource Control，RRC)消息和非接入层(NonAccess，NAS)消息传输的无线承载。SRB包括SRB0、SRB1和SRB2。
下面先对为目标RB配置PDCP数据复制功能、多个配置路径和多个激活路径的过程进行说明。
可选地，作为一个例子，在上述步骤101之前，也即在确定PDCP非复制数据包的承载路径之前，图1所示的方法还可以包括：接收第一信息，所述第一信息用于给所述目标RB配置PDCP数据复制功能；基于所述第一信息给所述目标RB配置PDCP数据复制功能。
第一信息可以承载在无线资源控制(Radio Resource Control，RRC)消息中，也即终端设备可以通过接收RRC消息来接收第一信息，或者说，网络设备可以通过RRC消息给终端设备的目标RB配置PDCP数据复制功能。
进一步地，在上述例子的基础上，图1所示的方法还可以包括：基于预设激活方式激活所述目标RB的PDCP数据复制功能。例如，网络设备可以先通过RRC消息给目标RB配置PDCP数据复制功能，然后通过媒体接入控制层控制信令(Medium Access Control Element，MAC CE)指示激活(开启)或去激活(停止)目标RB的该功能；或者，网络侧可以在通过RRC消息给目标RB配置该功能的同时，通过该RRC消息配置该功能是否在配置后立即激活，也即不需要再通过MAC CE信令额外激活该功能。
可选地，作为另一个例子，在上述步骤101之前，也即在确定PDCP非复制数据包的承载路径之前，图1所示的方法还可以包括：接收第二信息，所述第二信息用于给所述目标RB配置所述多个配置路径；基于所述第二信息确定所述多个配置路径。
第二信息也可以承载在RRC消息中。可选地，承载第一信息和第二信息的RRC消息可以是同一RRC消息，例如，网络设备可以在通过RRC消息给终端设备的目标RB配置PDCP数据复制功能的同时，通过该RRC消息配置所述多个配置路径(如配置路径(leg)1、路径2和路径3)。
或者，第二信息可以承载在MAC CE中，也即终端设备可以通过接收 MAC CE来接收第二信息，或者说，网络设备可以通过MAC CE给终端设备的目标RB配置所述多个配置路径。
可选地，作为又一个例子，在上述步骤101之前，也即在确定PDCP非复制数据包的承载路径之前，图1所示的方法还可以包括：接收第三信息，所述第三信息用于指示所述多个激活路径；基于所述第三信息确定所述多个激活路径。
第三信息也可以承载在RRC消息中，或者，第三信息可以承载在MAC CE中。可选地，当第一信息、第二信息和第三信息均承载在RRC消息中时，承载第一信息、第二信息和第三信息的RRC消息可以是同一RRC消息。例如，网络设备可以在通过RRC消息给终端设备的目标RB配置PDCP数据复制功能的同时，通过该RRC消息配置所述多个配置路径(如配置路径(leg)1、路径2和路径3)和所述多个激活路径(如配置激活路径1和路径2)。
又如，网络设备可以在通过RRC消息给终端设备的目标RB配置PDCP数据复制功能的同时，通过该RRC消息配置所述多个配置路径(如配置路径(leg)1、路径2和路径3)，然后通过MAC CE给终端设备配置所述多个激活路径(如配置激活路径1和路径2)。
在上述例子中，网络设备无论是在配置所述多个配置路径还是所述多个激活路径时，都可以通过配置路径的标识信息完成路径的配置。下面以配置所述多个激活路径为例，对基于路径的标识信息完成路径的配置进行说明。
可选地，在一个更为详细的例子中，上述第三信息用于指示所述多个激活路径的标识信息，所述基于所述第三信息确定所述多个激活路径，包括：基于所述第三信息中指示的所述多个激活路径的标识信息，确定所述多个激活路径。其中，所述标识信息包括RB标识(如DRB1或SRB1)、逻辑信道标识(如逻辑信道1)、小区组标识(如，主小区组(Master Cell Group，MCG)或辅小区组(Secondary Cell Group，SCG))和数据流标识(如，QoS flow 1)中的至少一种。
下面结合详细的例子，对步骤101中具体如何确定目标RB的PDCP非复制数据包的承载路径进行说明。
通过步骤101可知，本公开的一些实施例要么在所述多个配置路径中确 定目标RB的PDCP非复制数据包的承载路径，要么在所述多个激活路径中确定目标RB的PDCP非复制数据包的承载路径。
在第一个例子中，终端设备在所述多个激活路径中确定目标RB的PDCP非复制数据包的承载路径，具体可以基于第一预设方式在所述多个激活路径中确定所述承载路径，也就是说，所述承载路径是基于第一预设确定方式确定的。
其中，第一预设确定方式可以包括但不限于如下第一种方式、第二种方式、第三种方式和第四种方式中的任一种。
第一种方式包括：基于网络设备的指示信息，在所述多个激活路径中确定所述承载路径。也即网络设备可以通过所述指示信息，在所述多个激活路径中指定一个路径作为所述承载路径。
其中，所述指示信息可承载在RRC消息或MAC CE中。
进一步地，所述指示信息可以承载在上文中用于承载第一信息、第二信息和第三信息的RRC消息中。例如，网络设备可以在通过RRC消息给目标RB配置PDCP数据复制功能的同时，通过该RRC消息配置所述多个配置路径(如配置路径(leg)1、路径2和路径3)和所述多个激活路径(如配置激活路径1和路径2)，并通过该RRC消息指示所述多个激活路径中的特定路径(如路径1)用于承载PDCP非复制数据包。
或者，进一步地，所述指示信息可以承载在上文中用于承载第二信息和/或第三信息的MAC CE中。例如，网络设备可以在通过MAC CE配置所述多个激活路径(如配置激活路径1和路径2)的同时，通过该MAC CE指示所述多个激活路径中的特定路径(如路径1)用于承载PDCP非复制数据包。
第二种方式包括：基于第一预设规则，在所述多个激活路径中确定所述承载路径。其中，第一预设规则由协议约定，也即由协议约定一个用于承载PDCP非复制数据包的激活路径；或者，第一预设规则可以包括：在所述多个激活路径中任选一个路径作为所述承载路径，例如，假如所述多个激活路径包括路径1和路径2，那么可以在路径1和路径2中随机或按照任意规则选择一个路径作为所述承载路径。
在第二种方式中，当所述第一预设规则由协议约定时，第一预设规则可 以包括但不限于下列三个规则中的任一种。
第一个规则，在所述多个激活路径中与主小区组MCG的逻辑信道(Logical Channel,LCH)对应的路径中，确定所述承载路径。
具体的，在第一个规则中，终端设备可以将MCG中的逻辑信道对应的任一激活路径作为所述承载路径，也即所述承载路径可以为MCG中的逻辑信道对应的任一激活路径。
或者，在第一个规则中，终端设备可以将MCG中的逻辑信道编号满足第二预设条件的激活路径作为所述承载路径，也即所述承载路径可以为MCG中的逻辑信道编号满足第二预设条件的激活路径。举例来说，第二预设条件可以包括逻辑信道编号最大、逻辑信道编号最小、逻辑信道编号为偶数或逻辑信道编号为奇数等条件中的一个或多个。例如，假如第二预设条件为逻辑信道编号最大，且所述MCG中包括路径1和路径2两个激活路径，这两个激活路径对应的MCG的逻辑信道编号分别为LCH1和LCH2，则可以将LCH2对应的激活路径(路径2)作为所述承载路径。
需要说明的是，在本公开的一些实施例中，与MCG的逻辑信道对应的激活路径，是指MCG中的激活路径；同理，下文中的与SCG的逻辑信道对应的激活路径，是指SCG中的激活路径。
第二个规则，在所述多个激活路径中与辅小区组SCG的逻辑信道对应的路径中，确定所述承载路径。
具体的，在第二个规则中，终端设备可以将SCG中的逻辑信道对应的任一激活路径作为所述承载路径，也即所述承载路径可以为SCG中的逻辑信道对应的任一激活路径；
或者，在第二个规则中，终端设备可以将SCG中的逻辑信道编号满足第三预设条件的激活路径作为所述承载路径，也即所述承载路径可以为SCG中的逻辑信道编号满足第三预设条件的激活路径。举例来说，第三预设条件可以包括逻辑信道编号最大、逻辑信道编号最小、逻辑信道编号为偶数或逻辑信道编号为奇数等条件中的一个或多个。例如，假如第三预设条件为逻辑信道编号最小，且所述SCG中包括路径1和路径2两个激活路径，这两个激活路径对应的SCG的逻辑信道编号分别为LCH1和LCH2，则可以将LCH1对 应的激活路径(路径2)作为所述承载路径。
第三个规则，终端设备可以直接将所述多个激活路径中逻辑信道编号满足第一预设条件的路径，确定为所述承载路径。也即不区分MCG中或SCG中的激活路径，直接基于逻辑信道编号是否满足第一预设条件来确定所述承载路径。举例来说，第一预设条件可以包括逻辑信道编号最大、逻辑信道编号最小、逻辑信道编号为偶数或逻辑信道编号为奇数等条件中的一个或多个。例如，假如第一预设条件为逻辑信道编号最小，且所述多个激活路径包括路径1和路径2，对应的逻辑信道编号分别为LCH1和LCH2，则可以将LCH1对应的激活路径(路径1)作为所述承载路径。
第三种方式包括：基于激活路径所关联的无线链路控制(Radio Link Control，RLC)实体的模式，在所述多个激活路径中确定所述承载路径。
举例来说，当所述多个激活路径中的至少一个路径关联的RLC实体的模式为确认模式(AM)，且所述多个激活路径中的至少一个路径关联的RLC实体的模式为非确认模式(UM)时，所述承载路径为所述多个激活路径中关联的RLC实体的模式为AM的路径。例如，如果所述多个激活路径包括路径1和路径2，其中，路径1关联的RLC实体的模式为AM，路径2关联的RLC实体的模式为UM，则可以将路径1确定为所述承载路径。
可以理解，当基于上述第三种方式在所述多个激活路径中确定所述承载路径时，由于考虑了所述多个激活路径关联的RLC实体的模式，并且是将关联的RLC实体的模式为AM的激活路径确定为所述承载路径，因此可以使目标RB的PDCP非复制数据包在信道质量好的路径中发送，从而可以提高PDCP非复制数据包的传输可靠性和/或降低PDCP非复制数据包的传输时延。
第四种方式包括：基于激活路径的信道质量测量结果，在所述多个激活路径中确定所述承载路径。
具体的，终端设备可以将所述多个激活路径中信道质量最好的路径作为所述承载路径，也即所述承载路径可以为所述多个激活路径中信道质量最好的路径。其中，信道质量的好坏可以通过预设信道质量参数来表征。
例如，假如所述多个激活路径包括路径1和路径2，预设信道质量参数为参考信号接收功率(Reference Signal Receiving Power，RSRP)，且路径1 的RSRP大于路径2的RSRP，说明路径1的信道质量最好，进而可以将路径1作为PDCP复制数据包的承载路径。
或者，终端设备可以将所述多个激活路径中预设信道质量参数高于或低于预设门限值的路径作为所述承载路径，也即所述承载路径可以为所述多个激活路径中预设信道质量参数高于或低于预设门限值的路径。
例如，假如所述多个激活路径包括路径1和路径2，预设信道质量参数为RSRP，预设门限值为RSRP＝-20dBm，且路径1的RSRP高于该预设门限值，而路径2的RSRP低于该预设门限值，说明路径1的信道质量较好，进而可以将路径1作为PDCP复制数据包的承载路径。
其中，预设门限值可以由网络设备配置，也可以由协议约定。
除了RSRP，预设信道质量参数还可以是参考信号接收质量(Reference Signal Received Quality，RSRQ)、参考信号时间偏差(Reference signal time difference，RSTD)、接收信号强度指示(Received Signal Strength Indicator，RSSI)、误块率(Block Error Rate，BLER)、信道占用率(Channel occupancy ratio，CR)、信道繁忙率(Channel busy ratio，CBR)和信号干扰噪声比(Signal-to-Noise and Interference Ratio，SINR)中的至少一种。
可以理解，将所述多个激活路径中预设信道质量参数高于或低于预设门限值的路径作为所述承载路径，旨在将所述多个激活路径中信道质量较优的路径作为所述承载路径。需要说明的是，在基于预设信道质量参数确定信道质量较优的路径时，不同的信道质量参数与预设门限值的匹配关系不同，例如，在基于RSRP确定信道质量较优的路径时，具体是将RSRP高于预设门限值的路径确定为信道质量较优的路径，而在基于BLER确定信道质量较优的路径时，则是将BLER低于预设门限值的路径确定为信道质量较优的路径。
还需要说明的是，当基于上述第四种方式在所述多个激活路径中确定所述承载路径时，由于考虑了所述多个激活路径的信道质量，并且是将信道质量最好或较优的激活路径确定为所述承载路径，因此可以使目标RB的PDCP非复制数据包在信道质量好的路径中发送，从而可以提高PDCP非复制数据包的传输可靠性和/或降低PDCP非复制数据包的传输时延。
在第二个例子中，终端设备可以在所述配置激活路径中确定目标RB的 PDCP非复制数据包的承载路径，具体可以基于第二预设规则在所述多个激活路径中确定所述承载路径，也就是说，所述承载路径是基于第二预设规则在所述多个激活路径中确定的。
具体的，第二预设规则可以包括：在所述多个配置路径中任选一个路径作为所述承载路径。例如，所述多个配置路径包括路径1、路径2、路径3和路径4，所述多个激活路径包括所述多个配置路径中的路径1和路径2，则终端设备可以在路径1、路径2、路径3和路径4中任选一个路径作为PDCP非复制数据包的承载路径，可选地，终端设备可以将路径1、路径2作为PDCP复制数据包的承载路径。
总之，本公开的一些实施例提供的一种数据包承载路径确定方法，由于终端设备可以在目标RB的多个配置路径中或所述多个配置路径中的多个激活路径中，确定所述PDCP非复制数据包的承载路径，所述目标RB为配置了PDCP数据复制功能的RB，因此，可以使发送目标RB的非复制数据包的承载路径清楚明确。
可选地，如果通过步骤101确定出的承载路径有多个时，图1所示的方法还可以包括：在确定出的多个所述承载路径中，任选一个承载路径作为目标承载路径；并通过所述目标承载路径发送所述PDCP非复制数据包。
相应的，如果通过步骤101确定出的承载路径为一个时，图1所示的方法还可以包括：将确定出的承载路径作为目标承载路径，并通过所述目标承载路径发送所述PDCP非复制数据包。
可选地，图1所示的方法还可以包括：向所述终端设备的MAC层，上报通过所述目标承载路径发送的所述PDCP非复制数据包的数据量，以提高通信有效性。
需要说明的是，在本公开的一些实施例中，目标RB的PDCP非复制数据包可以包括但不限于PDCP状态包(PDCP Status PDU)、鲁棒头压缩(Robust Header Compression，ROHC)控制包、上行数据压缩(Uplink Data Compression，UDC)控制包和以太网头压缩控制包中的至少一种。
其中，ROHC控制包，例如可以是散布式ROHC反馈包(interspersed ROHC feedback packet)。UDC控制包，例如可以是UDC反馈包(UDC feedback  packet)。以太网头压缩控制包，例如可以是以太网络头压缩反馈包(Ethernet header compression feedback packet)，等等，本文不一一列举。
以上对应用于终端设备的一种数据包承载路径确定方法进行了说明，下面将通过图2对应用于终端设备的另一种数据包承载路径确定方法进行说明。需要说明的是，本公开的一些实施例提供的各数据包承载路径确定方法可以组合实施也可以单独实施，也即图1和图2所示的方法既可以单独实施也可以组合实施。
如图2所示，本公开的一些实施例提供的另一种数据包承载路径确定方法，应用于终端设备，该方法可以包括：
步骤201、在目标无线承载RB的多个配置路径中的多个激活路径中，确定所述目标RB对应的分组汇聚协议PDCP复制数据包的至少一个承载路径，所述目标RB为配置了PDCP数据复制功能的RB。
其中，多个配置路径是网络设备为目标无线承载(Radio Bearer，RB)配置的多个用于数据包发送的路径。多个激活路径是网络设备在配置多个配置路径的同时或配置多个配置路径之后，进一步激活的所述多个配置路径中的多个路径。多个配置路径可以是多个无线链路控制(Radio Link Control，RLC)实体。目标RB可以是特定RB，例如，DRB1或SRB1。
同对图1所示的实施例的说明，下面先对为目标RB配置PDCP数据复制功能、多个配置路径、多个激活路径和复制份数的过程进行说明。
可选地，作为一个例子，在上述步骤201之前，也即在确定PDCP复制数据包的至少一个承载路径之前，图2所示的方法还可以包括：接收第一信息，所述第一信息用于给所述目标RB配置PDCP数据复制功能；并基于所述第一信息给所述目标RB配置PDCP数据复制功能。
第一信息可以承载在RRC消息中，也即终端设备可以通过接收RRC消息来接收第一信息，或者说，网络设备可以通过RRC消息给终端设备的目标RB配置PDCP数据复制功能。
进一步地，在上述例子的基础上，图2所示的方法还可以包括：基于预设激活方式激活所述目标RB的PDCP数据复制功能。例如，网络设备可以先通过RRC消息给目标RB配置PDCP数据复制功能，然后通过MAC CE 指示激活(开启)或去激活(停止)目标RB的该功能；或者，网络侧可以在通过RRC消息给目标RB配置该功能的同时，通过该RRC消息配置该功能是否在配置后立即激活，也即不需要再通过MAC CE信令额外激活该功能。
可选地，作为另一个例子，在上述步骤201之前，也即在确定PDCP复制数据包的至少一个承载路径之前，图2所示的方法还可以包括：接收第二信息，所述第二信息用于给所述目标RB配置所述多个配置路径；基于所述第二信息确定所述多个配置路径。
第二信息也可以承载在RRC消息中，或者，第二信息可以承载在MAC CE中。当通过RRC消息承载第一信息和第二信息时，承载第一信息和第二信息的RRC消息可以是同一RRC消息。
可选地，作为又一个例子，在上述步骤201之前，也即在确定PDCP复制数据包的至少一个承载路径之前，图2所示的方法还可以包括：接收第三信息，所述第三信息用于指示所述多个激活路径；基于所述第三信息确定所述多个激活路径。
第三信息可以承载在RRC消息中，或者，第三信息可以承载在MAC CE中。可选地，当第一信息、第二信息和第三信息均通过RRC消息承载时，承载第一信息、第二信息和第三信息的RRC消息可以是同一RRC；当第一信息承载在RRC消息中，第二信息和第三信息承载在MAC CE中时，承载第二信息和第三信息的MAC CE可以为同一MAC CE。
在上述例子中，网络设备无论是在配置所述多个配置路径还是所述多个激活路径时，都可以通过配置路径的标识信息完成路径的配置。下面以配置所述多个激活路径为例，对基于路径的标识信息完成路径的配置进行说明。
例如，在一个更为详细的例子中，上述第三信息可用于指示所述多个激活路径的标识信息，相应的，所述基于所述第三信息确定所述多个激活路径，可以包括：基于所述第三信息中指示的所述多个激活路径的标识信息，确定所述多个激活路径。其中，所述标识信息包括RB标识(如DRB1或SRB1)、逻辑信道标识(如逻辑信道1)、小区组标识(如，MCG或SCG)和数据流标识(如，QoS flow 1)中的至少一种。
可选地，作为又一个例子，在上述步骤201之前，也即在确定PDCP复 制数据包的至少一个承载路径之前，图2所示的方法还可以包括：接收第四信息，所述第四信息用于配置所述PDCP复制数据包的复制份数；基于所述第四信息，确定所述复制份数。
其中，第四信息也可以承载在RRC消息中，或者，第四信息可以承载在MAC CE中。
总的来说，第一信息可以承载在RRC消息中，第二信息、第三信息和第四信息既可以承载在RRC消息中，也可以承载在MAC CE中。下面通过三个详细的例子，对第一信息、第二信息、第三信息和第四信息的承载情况进行说明。
例如，网络设备可以在通过RRC消息给终端设备的目标RB配置PDCP数据复制功能的同时，通过该RRC消息配置所述多个配置路径(如给DRB1配置路径1、路径2、路径3和路径4)并配置激活其中的多个路径(如配置激活路径1和路径2)，以及通过该RRC消息配置PDCP复制数据包的复制份数为3。
再如，网络设备可以在通过RRC消息给终端设备的目标RB配置PDCP数据复制功能的同时，通过该RRC消息配置所述多个配置路径(如给DRB1配置路径1、路径2、路径3和路径4)，并通过该RRC消息配置PDCP复制数据包的复制份数为3；然后通过MAC CE给终端设备配置所述多个激活路径(如配置激活路径1和路径2)。
又如，网络设备可以在通过RRC消息给终端设备的目标RB配置PDCP数据复制功能的同时，通过该RRC消息配置所述多个配置路径(如给DRB1配置路径1、路径2、路径3和路径4)。然后通过MAC CE给终端设备配置所述多个激活路径(如配置激活路径1和路径2)，并通过该MAC CE配置PDCP复制数据包的复制份数为3。
下面结合详细的例子，对步骤201中具体如何确定目标RB的PDCP复制数据包的至少一个承载路径进行说明。
作为一个例子，步骤201具体可以包括：基于第二预设确定方式，在所述多个激活路径中确定所述至少一个承载路径。
其中，所述第二预设确定方式可以包括但不限于下列第一种方式、第二 种方式和第三种方式中的任一种。
第一种方式包括：基于激活路径的信道质量测量结果，在所述多个激活路径中确定所述至少一个承载路径。
具体的，在第一种方式中，可以将所述多个激活路径中信道质量最好的路径确定为所述至少一个承载路径，也即所述至少一个承载路径为所述多个激活路径中信道质量最好的路径。其中，信道质量的好坏可以通过预设信道质量参数来表征。
举例来说，假如所述多个激活路径包括路径1和路径2，预设信道质量参数为参考信号接收功率(Reference Signal Receiving Power，RSRP)，且路径1的RSRP大于路径2的RSRP，说明路径1的信道质量最好，进而可以将路径1作为PDCP复制数据包的承载路径。
或者，在第一种方式中，可以将所述多个激活路径中预设信道质量参数高于或低于预设门限值的路径确定为所述至少一个承载路径，也即所述至少一个承载路径为所述多个激活路径中预设信道质量参数高于或低于预设门限值的路径。其中，预设门限值可以由网络设备配置，也可以由协议约定。
举例来说，假如所述多个激活路径包括路径1和路径2，预设信道质量参数为RSRP，预设门限值为RSRP＝-20dBm，且路径1的RSRP高于该预设门限值，而路径2的RSRP低于该预设门限值，说明路径1的信道质量较好，进而可以将路径1作为PDCP复制数据包的承载路径。
第二种方式包括：基于激活路径所关联的RLC实体的模式，在所述多个激活路径中确定所述至少一个承载路径。
具体的，在第二种方式中，当所述多个激活路径关联的RLC实体的模式均为非确认模式UM时，可以进一步地基于所述多个激活路径的信道质量测量结果确定所述至少一个承载路径，也即所述至少一个承载路径是基于所述多个激活路径的信道质量测量结果确定的。
例如，可以将所述多个激活路径中信道质量最好的路径确定为所述至少一个承载路径，也即所述至少一个承载路径为所述多个激活路径中信道质量最好的路径；或者，可以将所述多个激活路径中预设信道质量参数高于或低于预设门限值的路径确定为所述至少一个承载路径，也即所述至少一个承载 路径为所述多个激活路径中预设信道质量参数高于或低于预设门限值的路径。其中，预设门限值可以由网络设备配置，也可以由协议约定。
在第一种确定方式和第二种确定方式中，所述预设信道质量参数可以包括参考信号接收功率RSRP、参考信号接收质量RSRQ、参考信号时间偏差RSTD、接收信号强度指示RSSI、误块率BLER、信道占用率CR、信道繁忙率CBR和信号干扰噪声比SINR等参数中的至少一种。
可以理解，将所述多个激活路径中信道质量最好的激活路径，或将所述多个激活路径中预设信道质量参数高于或低于预设门限值的路径作为所述至少一个承载路径，旨在将所述多个激活路径中信道质量较优的路径作为所述至少一个承载路径。需要说明的是，在基于预设信道质量参数确定信道质量较优的路径时，不同的信道质量参数与预设门限值的匹配关系不同，例如，在基于RSRP确定信道质量较优的路径时，具体是将RSRP高于预设门限值的路径确定为信道质量较优的路径，而在基于BLER确定信道质量较优的路径时，则是将BLER低于预设门限值的路径确定为信道质量较优的路径。
或者，在第二种方式中，当所述多个激活路径关联的RLC实体的模式均为确认模式AM时，可以基于网络设备配置的PDCP复制数据包的复制份数确定所述至少一个承载路径，也即所述至少一个承载路径是基于所述复制份数确定的。
可选地，当在第二种方式中，所述至少一个承载路径是基于所述复制份数确定的时，图2所示的方法还可以包括：将所述复制份数的PDCP复制数据包，分别通过所述至少一个承载路径发送，其中，复制得到的不同PDCP复制数据包对应的承载路径不同。也即将复制的到多份复制数据包分别通过所述至少一个承载路径中的不同路径发送。
例如，假如目标RB的多个激活路径包括路径1和路径2，且路径1和路径2关联的RLC实体的模式均为AM，且PDCP复制数据的复制份数为2，则可以将复制得到的2份数据包分别通过路径1和路径2发送。
可以理解，在第一种确定方式和第二种确定方式中，由于考虑了所述多个激活路径关联的RLC实体的模式、多个激活路径的信道质量以及PDCP复制数据包的复制份数等因素中的至少一个，因此可以提高PDCP复制数据包 的传输可靠性和/或降低PDCP复制数据包的传输时延。
第三种方式包括：基于第三预设规则，在所述多个激活路径中确定所述至少一个承载路径。
具体的，第三预设规则可以包括：在所述多个配置路径中任选一个或多个路径作为所述至少一个承载路径。例如，所述多个配置路径包括路径1、路径2、路径3和路径4，所述多个激活路径包括所述多个配置路径中的路径1和路径2，则终端设备可以在路径1和路径2中任选一个或两个路径作为PDCP复制数据包的承载路径。
总之，本公开的一些实施例提供的一种数据包承载路径确定方法，由于终端设备可以在目标RB的多个配置路径中的多个激活路径中，确定所述目标RB对应的PDCP复制数据包的至少一个承载路径，而不仅仅是由网络侧指定，因此可以提高发送复制数据包的承载路径的灵活性。
可选地，图2所示的方法还可以包括：通过所述至少一个承载路径，发送所述复制份数的PDCP复制数据包。
可选地，图2所示的方法还可以包括：向所述终端设备的MAC层，上报通过所述承载路径发送的PDCP复制数据包的数据量，以提高通信有效性。
下面通过图3A、图3B、图4A和图4B，对图1所示的实施例和图2所示的实施例中的PDCP数据复制功能的承载类型，以及多路径PDCP数据复制的原理进行简要地介绍。
作为一个例子，在5G系统中，由于采用了包括MCG和SCG两个小区组的双连接(Dual Connectivity，DC)架构，因此，PDCP数据复制功能的承载类型可以包括如图3A和如图3B所示的两种。
图3A所示的PDCP数据复制功能的承载类型为重复承载(Duplicate bearer)，在该承载类型的无线承载中，对应1的1个PDCP实体、2个或多个RLC实体以及1个MAC实体在同一个小区组中。例如，对于MCG中的PDCP实体，其对应的2个或多个RLC实体以及1个MAC实体均在MCG中；对于SCG中的PDCP实体，其对应的2个或多个RLC实体以及1个MAC实体均在SCG中。
图3B所示的PDCP数据复制功能的承载类型为分离承载(Split bearer)， 在该承载类型的无线承载中，对应的PDCP实体在1个小区组，对应的2个或多个RLC实体，以及对应的2个或多个MAC实体在不同的小区组中。
对于多路径PDCP数据复制(Mulitple Leg PDCP Duplication)，或称多路径重复承载(Multiple leg Duplicate Bearer)，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)，如图4A所示，可以配置在同一小区组的多个路径，或者如图4B所示，可以配置不在同一小区组的多个路径。配置之后，网络设备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个路径处于激活状态)。其中，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。
以上是对本公开的一些实施例提供的数据包发送路径确定方法的说明。下面对本公开的一些实施例提供的信息发送方法进行介绍。
如图5所示，本公开的一些实施例提供的一种信息发送方法，应用于网络设备，该方法可以包括：
步骤501、发送第一目标信息；其中，所述第一目标信息用于确定第一承载路径，所述第一承载路径用于承载终端设备的目标无线承载RB对应的分组汇聚协议PDCP非复制数据包，且所述第一承载路径为所述目标RB的多个配置路径中的激活路径。
在一个例子中，所述第一目标信息用于指示第一承载路径，也即所述第一目标信息中直接指示了第一承载路径是什么，例如，指示了第一承载路径的标识信息(标识信息的具体内容请参照上文，此处不再赘述)。更为详细的，此时第一目标信息可以携带在用于给终端设备的目标RB配置PDCP复制功能的RRC消息中。
在另一个例子中，所述第一目标信息用于配置预设信道质量参数对应的预设门限值，所述预设门限值用于确定所述第一承载路径，且所述第一承载路径的所述预设信道质量参数高于或低于所述预设门限值。也即，网络设备给终端设备指示了用于确定激活路径的信道质量好坏的预设门限值，以使终端设备在测量出激活路径的相应信道质量参数之后，通过与该预设门限值比较确定激活路径的信道质量的好坏，从而从激活路径中确定出信道质量较好 的路径以用于承载PDCP非复制数据包。
其中，所述预设信道质量参数包括参考信号接收功率RSRP、参考信号接收质量RSRQ、参考信号时间偏差RSTD、接收信号强度指示RSSI、误块率BLER、信道占用率CR、信道繁忙率CBR和信号干扰噪声比SINR中的至少一种。
图5所示的实施例提供的一种信息发送方法，由于网络设备可以给终端设备发送用于确定目标RB对应的PDCP非复制数据包的第一承载路径的第一目标信息，因此，可以使终端设备在用于承载目标RB对应的PDCP非复制数据包的主路径去激活时，能够确定出用于承载PDCP非复制数据包的其他路径，从而保证PDCP非复制数据能够顺利发送，提高了通信有效性。
如图6所示，本公开的一些实施例提供的一种信息发送方法，应用于网络设备，该方法可以包括：
步骤601、发送第二目标信息；其中，所述第二目标信息用于配置预设信道质量参数对应的预设门限值，所述预设门限值用于确定至少一个第二承载路径，所述第二承载路径用于承载终端设备的目标RB对应的PDCP复制数据包，所述第二承载路径为所述目标RB的多个配置路径中的激活路径，且所述第二承载路径的预设信道质量参数高于或低于所述预设门限值。
也即，网络设备给终端设备指示了用于确定目标RB的激活路径的信道质量好坏的预设门限值，以使终端设备在测量出激活路径的相应信道质量参数之后，通过与该预设门限值比较确定激活路径的信道质量的好坏，从而从激活路径中确定出信道质量较好的路径以用于承载PDCP复制数据包。
其中，所述预设信道质量参数包括参考信号接收功率RSRP、参考信号接收质量RSRQ、参考信号时间偏差RSTD、接收信号强度指示RSSI、误块率BLER、信道占用率CR、信道繁忙率CBR和信号干扰噪声比SINR中的至少一种。
图6所示的实施例提供的一种信息发送方法，由于网络设备可以给终端设备发送用于确定终端设备的目标RB对应的PDCP复制数据包的至少一个第二承载路径的预设门限值，因此，可以使终端设备据此灵活的确定出用于承载目标RB对应的PDCP复制数据包的路径。并且，由于确定出的第二承 载路径的预设信道质量参数高于或低于该预设门限值，说明确定出的第二承载路径的信道质量较好，因此可以提高PDCP复制数据包的传输可靠性，降低PDCP复制数据包的传输时延。

可选地，在一个更为详细的例子中，上述第三信息用于指示所述多个激活路径的标识信息，第三接收模块可用于：基于所述第三信息中指示的所述 多个激活路径的标识信息，确定所述多个激活路径。
下面结合详细的例子，对第一确定模块701具体如何确定目标RB的PDCP非复制数据包的承载路径进行说明。
第一确定模块701要么在所述多个配置路径中确定目标RB的PDCP非复制数据包的承载路径，要么在所述多个激活路径中确定目标RB的PDCP非复制数据包的承载路径。
在第一个例子中，第一确定模块701在所述多个激活路径中确定目标RB的PDCP非复制数据包的承载路径，具体可以基于第一预设方式在所述多个激活路径中确定所述承载路径，也就是说，所述承载路径是基于第一预设确定方式在所述多个激活路径中确定的。
其中，第一预设确定方式可以包括但不限于如下第一种方式、第二种方式、第三种方式和第四种方式中的任一种。
第一种方式包括：基于网络设备的指示信息，在所述多个激活路径中确定所述承载路径。也即网络设备可以通过所述指示信息，在所述多个激活路径中指定一个路径作为所述承载路径。
其中，所述指示信息可承载在RRC消息或MAC CE中。
第二种方式包括：基于第一预设规则，在所述多个激活路径中确定所述承载路径。其中，第一预设规则由协议约定，也即由协议约定一个用于承载PDCP非复制数据包的激活路径；或者，第一预设规则可以包括：在所述多个激活路径中任选一个路径作为所述承载路径。
在第二种方式中，当所述第一预设规则由协议约定时，第一预设规则可以包括但不限于下列三个规则中的任一种。
第一个规则，在所述多个激活路径中与主小区组MCG的逻辑信道(Logical Channel,LCH)对应的路径中，确定所述承载路径。
具体的，在第一个规则中，终端设备可以将MCG中的逻辑信道对应的任一激活路径作为所述承载路径，也即所述承载路径可以为MCG中的逻辑信道对应的任一激活路径。
或者，在第一个规则中，终端设备可以将MCG中的逻辑信道编号满足第二预设条件的激活路径作为所述承载路径，也即所述承载路径可以为MCG 中的逻辑信道编号满足第二预设条件的激活路径。
第二个规则，在所述多个激活路径中与辅小区组SCG的逻辑信道对应的路径中，确定所述承载路径。
具体的，在第二个规则中，终端设备可以将SCG中的逻辑信道对应的任一激活路径作为所述承载路径，也即所述承载路径可以为SCG中的逻辑信道对应的任一激活路径；
或者，在第二个规则中，终端设备可以将SCG中的逻辑信道编号满足第三预设条件的激活路径作为所述承载路径，也即所述承载路径可以为SCG中的逻辑信道编号满足第三预设条件的激活路径。
第三个规则，终端设备可以直接将所述多个激活路径中逻辑信道编号满足第一预设条件的路径，确定为所述承载路径。也即不区分MCG中或SCG中的激活路径，直接基于逻辑信道编号是否满足第一预设条件来确定所述承载路径。
第三种方式包括：基于激活路径所关联的RLC实体的模式，在所述多个激活路径中确定所述承载路径。
可以理解，当基于上述第三种方式在所述多个激活路径中确定所述承载路径时，由于考虑了所述多个激活路径关联的RLC实体的模式，并且是将关联的RLC实体的模式为AM的激活路径确定为所述承载路径，因此可以使目标RB的PDCP非复制数据包在信道质量好的路径中发送，从而可以提高PDCP非复制数据包的传输可靠性和/或降低PDCP非复制数据包的传输时延。
第四种方式包括：基于激活路径的信道质量测量结果，在所述多个激活路径中确定所述承载路径。
具体的，终端设备可以将所述多个激活路径中信道质量最好的路径作为所述承载路径，也即所述承载路径可以为所述多个激活路径中信道质量最好的路径。其中，信道质量的好坏可以通过预设信道质量参数来表征。

还需要说明的是，当基于上述第四种方式在所述多个激活路径中确定所 述承载路径时，由于考虑了所述多个激活路径的信道质量，并且是将信道质量最好或较优的激活路径确定为所述承载路径，因此可以使目标RB的PDCP非复制数据包在信道质量好的路径中发送，从而可以提高PDCP非复制数据包的传输可靠性和/或降低PDCP非复制数据包的传输时延。
在第二个例子中，第一确定模块701可以在所述配置激活路径中确定目标RB的PDCP非复制数据包的承载路径，具体可以基于第二预设规则在所述多个激活路径中确定所述承载路径，也就是说，所述承载路径是基于第二预设规则在所述多个激活路径中确定的。第二预设规则可以包括：在所述多个配置路径中任选一个路径作为所述承载路径。
