本申请要求在2020年05月22日提交中国国家知识产权局、申请号为202010441955.6、申请名称为“一种通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种通信方法及装置。
背景技术
在双连接(dual connectivity，DC)模式下，终端设备会同时与主网络设备和辅网络设备保持连接，而且主网络设备可以决定将终端设备的服务质量(Quality of Service，QoS)流建立在辅网络设备上。现有技术中，主网络设备可以基于自己的实现为QoS流选择一组QoS参数并指示给辅网络设备，但由于主网络设备可能并不知道辅网络设备的空口链路状况或辅网络设备的单板能力，因此，可能会出现主网络设备选择的QoS参数与辅网络设备实际能够保障的QoS不符的情况，进而导致用户业务的QoS无法得到保障，影响业务体验。
发明内容

请参考图3，为本申请实施例提供的一种通信方法的流程示意图，该方法包括：
步骤S301、第一网元向第二网元发送第一QoS流对应的N组QoS特征信息(QoS profiles)，N为大于或等于1的整数。
可选的，第一网元还可以向第二网元发送第一QoS流的标识(即QoS flow ID)。
在一种实施方式中，如图4a所示，终端设备可以被配置双连接，第一网元可以为终端设备接入的主网络设备，第二网元可以为终端设备接入的辅网络设备，第三网元可以为核心网设备，所述辅网络设备与主网络设备连接，该主网络设备进一步与核心网设备具有控制面连接，示例性地，所述核心网设备可以为接入与移动性管理功能(access and mobility management function，AMF)实体。在这一实施方式中，主网络设备可在决定将终端设备的第一QoS流分流到辅网络设备来传输时，将第一QoS流的标识以及第一QoS流对应的N组QoS特征信息发送给辅网络设备。可选的，主网络设备可以采用CU-DU的分离式架构，此时，所述主网络设备具体可以是指主网络设备中的CU；类似的，所述辅网络设备也可以采用CU-DU的分离式架构，此时，所述辅网络设备具体是指辅网络设备中的CU。
需要说明的是，在图4a所示的实施方式中，主网络设备可以在为终端设备配置好双连接后，执行步骤S301，向辅网络设备发送第一QoS流对应的N组QoS特征信息；或者，主网络设备也可以在为终端设备准备配置双连接的过程中，执行步骤S301至步骤S306中的方法，例如，主网络设备可以在添加辅网络设备时，与辅网络设备进行QoS特征信息的协商，向核心网设备上报辅网络设备选择的一组QoS特征信息，然后再为终端设备提供双连接的配置，本申请并不限定。
另一种实施方式中，如图4b所示，终端设备可以被配置双连接，且终端设备接入的辅网络设备采用CU-DU的分离式架构，第一网元可以为终端设备接入的辅网络设备中的CU，第二网元可以为终端设备接入的辅网络设备中的DU，所述辅网络设备与主网络设备连接，该主网络设备进一步与核心网设备连接，示例性地，所述核心网设备可以为AMF。在这一实施方式中，在主网络设备决定将终端设备的第一QoS流分流到辅网络设备传输的情况下，辅网络设备中的CU可从主网络设备接收第一QoS流的标识以及第一QoS流对应的N组QoS特征信息，然后将第一QoS流的标识以及第一QoS流对应的N组QoS特征信息发送给辅网络设备中的DU。
在又一种实施方式中，如图4c所示，终端设备接入的网络设备采用CU-DU的分离式架构，第一网元可以为终端设备接入的网络设备中的CU，第二网元可以为终端设备接入的网络设备中的DU，第三网元可以为核心网设备，该网络设备与核心网设备连接，示例性地，核心网设备可以为AMF。在这一实施方式中，终端设备接入的网络设备中的CU可从核心网设备接收第一QoS流的标识以及第一QoS流对应的N组QoS特征信息，然后将第一QoS流的标识以及第一QoS流对应的N组QoS特征信息发送给该网络设备中的DU。
本申请实施例中，所述QoS流对应的一组QoS特征信息可包括下列一项或多项QoS参数的取值：上行最大流比特率(maximum flow bit rate，MFBR)、下行MFBR、上行保证流比特率(guaranteed flow bit rate，GFBR)、下行GFBR、上行最大丢包率(maximum packet loss rate，MPLR)、下行MPLR、包延迟预算(packet delay budget，PDB)、错包率(packet error rate，PER)、第五代QoS指示(5G QoS identifier，5QI)、最大数据爆发量(maximum data burst volume，MDBV)、QoS流的优先级。当然，一组QoS特征信息中还可以包括其它QoS参数的取值，本申请在此不再一一列举。应注意，QoS流对应的一组QoS特征信 息也可以称为QoS流对应的一组/套QoS参数或QoS profile，或者具有其他名称，本申请并不限定。
举例来说，一组QoS特征信息中可包括上行MFBR、下行MFBR、上行GFBR和下行GFBR，其中，上行MFBR、下行MFBR、上行GFBR和下行GFBR的最大取值均为4Gbps。
步骤S302、第二网元从第一网元接收第一QoS流对应的N组QoS特征信息。
步骤S303、第二网元从所述N组QoS特征信息中为所述第一QoS流选择一组QoS特征信息。
步骤S304、第二网元向第一网元发送第一指示信息，该第一指示信息用于指示第二网元为第一QoS流选择的该组QoS特征信息，该组QoS特征信息为所述N组QoS特征信息之一。
本申请实施例中，第二网元可根据自身能够满足的QoS，从所述N组QoS特征信息中选择出能够满足的QoS要求最高的一组QoS特征信息，然后通过第一指示信息将选择出的该组QoS特征信息告知给第一网元。所述第一指示信息可以是选择出的该组QoS特征信息在所述N组QoS特征信息中的索引，或者也可以是该组QoS特征信息中包括的各个QoS参数的具体取值，本申请并不限定。
需要说明的是，在图4b和图4c所示的实施例中，由于第二网元采用CU-DU的分离式架构，因此在具体进行QoS特征信息选择的过程中，可以由CU来具体执行对QoS特征信息中包括的QoS参数的判断，也可以由DU来具体执行对QoS特征信息中QoS参数的判断，或者也可以是由CU来执行一部分QoS参数的判断，由DU来执行另一部分QoS参数的判断，本申请并不限定。
步骤S305、第一网元从第二网元接收第一指示信息。
可选的，第一网元还可以从第三网元接收第一QoS流的标识以及第一QoS流对应的M组QoS特征信息，然后根据接收到的M组QoS特征信息，确定所述N组QoS特征信息。其中，所述N组QoS特征信息可以是所述M组QoS特征信息的子集。例如，第一网元可以从第二网元接收用于指示第二网元能够满足的QoS的辅助信息，然后根据接收到的该辅助信息，从所述M组QoS特征信息中确定所述N组QoS特征信息，所述N组QoS特征信息是所述M组QoS特征信息的部分或全部组，或者说，第一网元发送给第二网元的一组或多组QoS特征信息与第一网元从第三网元接收的一组或多组QoS特征信息可以是相同或不同的。所述辅助信息中可以包括一组QoS特征信息中各个QoS参数的具体取值，表示第二网元能够保证的QoS。
也就是说，第一网元可以将从第三网元接收到的第一QoS流对应的M组QoS特征信息作为所述N组QoS特征信息直接转发给第二网元，此时N等于M；第一网元也可以对从第三网元接收到的第一QoS流对应的M组QoS特征信息进行筛选，将其中的部分组QoS特征信息(即所述N组QoS特征信息)发送给第二网元，此时N小于M。
可选的，在此基础上，第一网元从所述M组QoS特征信息中确定出N组QoS特征信息后，还可以进一步对该N组QoS特征信息中的一组或多组QoS特征信息中的一个或多个QoS参数的取值进行修改，得到最终的所述N组QoS特征信息。
举例来说，假设第一网元为终端设备接入的主网络设备，第二网元为终端设备接入的辅网络设备，第三网元为核心网设备，主网络设备可从核心网设备接收第一QoS流的标识以及第一QoS流对应的M组QoS特征信息。如果主网络设备决定将第一QoS流配置为锚 点在辅网络设备上的承载，那么主网络设备可以将从核心网设备接收的M组QoS特征信息发送给辅网络设备，由辅网络设备选择第一QoS流应用的一组QoS特征信息，并将选择的该组QoS特征信息的索引携带在第一指示信息中发送给主网络设备。
如果主网络设备决定将第一QoS流配置为锚点在主网络设备上的承载，那么主网络设备可从接收到的M组QoS特征信息中确定出N组QoS特征信息，然后将该N组QoS特征信息发送给辅网络设备，由辅网络设备选择第一QoS流应用的一组QoS特征信息，并将选择的该组QoS特征信息的索引携带在第一指示信息中发送给主网络设备。其中，所述N组QoS特征信息可以与所述M组QoS特征信息不同，所述不同可以是指N组与M组的数量不同或者N组QoS特征信息中的任意一组或多组内的具体的QoS参数的取值与M组QoS特征信息中的一组或多组内的具体的QoS参数的取值不同。例如，主网络设备可在M组QoS特征信息中去掉几组QoS特征信息，然后将剩下的N组QoS特征信息发送给辅网络设备，或者主网络设备还可以进一步对剩下的N组QoS特征信息中的某一组或多组QoS特征信息中的某一项或多项QoS参数的具体取值进行修改，得到最终的N组QoS特征信息，此时N为小于M的整数；再或者，主网络设备也可以直接对M组QoS特征信息中的一组或多组QoS特征信息中的一项或多项QoS参数的具体取值进行修改，得到最终的M组QoS特征信息，此时N等于M，所述M组QoS特征信息即为N组QoS特征信息。
步骤S306、第一网元向第三网元发送第二指示信息，该第二指示信息用于指示为第一QoS流选择的该组QoS特征信息。
本申请实施例中，所述第二指示信息可以是选择出的该组QoS特征信息在所述M组QoS特征信息中的索引，或者也可以是该组QoS特征信息中包括的各个QoS参数的具体取值，本申请并不限定。
应注意的是，本申请实施例中，若第一指示信息和第二指示信息采用的都是索引，那么该第一指示信息与第二指示信息的取值可以相同或不同，但是指示的一组QoS特征信息是相同的。即，第一指示信息和第二指示信息用于指示同一组QoS特征信息，但该组QoS特征信息在第一网元发送给第二网元的所述N组QoS特征信息中的索引，与该组QoS特征信息在第一网元从第三网元接收的所述M组QoS特征信息中的索引可以是相同或不同的。这可能是因为第一网元向第三网元发送的所述N组QoS特征信息，与第一网元从第三网元接收的所述M组QoS特征信息的数量不同，即N小于M。即使N等于M，第一网元将从第三网元接收到的M组QoS特征信息不作删减地发送给第二网元，那么第一网元在发送所述M组QoS特征信息时，也有可能改变所述M组QoS特征信息之间的排列顺序，进而导致同一组QoS特征信息的索引改变。
图5a和图5b为本申请实施例提供的一种通信方法的两个具体示例。如图5a所示，终端设备已配置有双连接，第一网元为终端设备接入的主网络设备，第二网元为终端设备接入的辅网络设备，第三网元为AMF。在步骤S501中，AMF可向主网络设备发送第一QoS流的标识(例如QFI)，以及选择的多组QoS特征信息。可选的，由于可能存在多个协议数据单元(protocol data unit，PDU)会话，且不同PDU会话中的QoS流的标识可能相同，因此，在步骤S501中，AMF还可向主网络设备发送第一QoS流所在的PDU会话的标识。在步骤S502中，主网络设备可将从AMF接收到的第一QoS流的标识以及供选择的多组QoS特征信息发送给辅网络设备。在步骤S503中，辅网络设备可将第一QoS流的标识， 以及根据辅网络设备自身能够满足的服务质量从供选择的多组QoS特征信息选择的一组参考QoS特征信息，发送给主网络设备。在步骤S504中，主网络设备可将第一QoS流的标识以及选择的一组参考QoS特征信息发送给AMF。
如图5b所示，可包含两种可能的应用场景，其中一种应用场景为：终端设备未配置双连接，第一网元为终端设备接入的网络设备的CU，第二网元为终端设备接入的网络设备的DU，第三网元为AMF，或者终端配置有双连接，所述网络设备具体是指终端设备接入的主网络设备。第一种应用场景为：终端设备配置有双连接，第一网元为终端设备接入的辅网络设备的CU，第二网元为终端设备接入的辅网络设备中的DU，第三网元为终端设备接入的主网络设备；图5b中所示的流程与图5a中类似，在此不再展开描述。
可选的，在一种可能的实施方式中，第一网元可从第二网元接收辅助信息，该辅助信息用于指示第二网元能够满足的QoS，可选的，该辅助信息用于指示第二网元能够满足的要求最高的QoS。如此，第一网元从第三网元接收到第一QoS流对应的M组QoS特征信息后，可根据该辅助信息，从中选择第二网元能够满足的QoS要求最高的一组QoS特征信息，然后将该组QoS特征信息发送给第二网元。进而，第一网元可在接收到来自第二网元对该组QoS特征信息的确认信息(例如ACK)后，向第三网元发送第二指示信息，该第二指示信息用于指示选择的该组QoS特征信息。
由此可知，本申请实施例中，接入侧的两个节点可以是终端设备接入的主网络设备和辅网络设备。若主网络设备决定将第一QoS流分流到辅网络设备传输，那么主网络设备可将第一QoS流对应的多组QoS特征信息发送给辅网络设备，由辅网络设备从中为第一QoS流选择应用的QoS特征信息，进而再向主网络设备指示选择的该组QoS特征信息。如此，通过采用该技术方案，辅网络设备可参与到QoS特征信息的选择中，从而确保分流到辅网络设备的第一QoS流的QoS参数可与辅网络设备能够满足的QoS相匹配，有效保障业务的服务质量，改善用户的业务体验。
类似的，接入侧的两个节点可以是终端设备接入的网络设备中的CU和DU。由于业务的QoS流通常会承载在DU上传输，因此通过CU向DU发送QoS流对应的多组QoS特征信息，由DU从中选择一组合适的QoS特征信息，并反馈给CU，可使得最终选择的QoS特征信息能够与DU能够保障的服务质量相匹配，从而有效保障业务的服务质量，改善用户的业务体验。
可选的，在一种可能的实施方式中，QoS特征信息中的部分QoS参数的选择可以由CU完成，剩余部分QoS参数的选择可以由DU完成。此时CU向DU发送的QoS特征信息与CU从核心网或者主网络设备收到的QoS特征信息可以不同，具体的，CU发给DU的QoS特征信息包含的QoS参数可以是CU收到的QoS特征信息中包含的QoS参数的一部分。
请参考图6，为本申请实施例提供的另一种通信方法的流程示意图，该方法包括：
步骤S601、主网络设备向辅网络设备发送第一指示信息，该第一指示信息用于指示辅网络设备开启终端设备的高速(high speed)模式。
其中，主网络设备也可以称为主节点，例如可以是主基站；辅网络设备也可以称为辅节点，例如可以是辅基站。
本申请实施例可以应用于终端设备处于高速移动状态的场景下，例如高铁、高速公路 等。在这一场景下，网络设备(例如主网络设备或辅网络设备)可以为接入的终端设备开启高速模式，例如，网络设备可以通过某种预设的算法来判断终端设备是否处于高速移动中或是否属于高速用户，进而决策是否为该终端设备开启高速模式。作为一种示例，网络设备可以检测终端设备的移动速度，并将检测到的移动速度超过某一设定阈值的终端设备确定为高速用户，进而为该终端设备开启高速模式。所述高速模式是指网络设备可以为该终端设备提供专用的物理层配置，这些配置又可以称为高速配置，所述高速配置用于指示终端设备按照高速模式下增强的无线资源管理(radio resource management，RRM)要求工作，和/或，指示终端设备按照高速模式下的解调性能要求工作，所述高速配置也可以称为高速增强配置。
在为终端设备开启高速模式的基础上，网络设备还可以决策为接入的终端设备配置双连接。应注意，本申请实施例中对为终端设备开启高速模式，以及为终端设备配置双连接的先后顺序不作限定。
在步骤S601的具体实施中，主网络设备可在决定开启终端设备的高速模式后，向辅网络设备发送第一指示信息，以指示辅网络设备也开启该终端设备的高速模式，从而使得主网络设备与辅网络设备之间能够保持高速模式的同步，即保持高速模式开启的一致性。鉴于此，所述第一指示信息也可以理解为用于指示主网络设备决定开启终端设备的高速模式。
应注意，在主网络设备决定开启终端设备的高速模式后，主网络设备可以立即开启该终端设备的高速模式，如向终端设备发送主网络设备生成的高速配置，以使终端设备能够尽快地应用这些高速配置；或者，主网络设备也可以通过与辅网络设备协商确定一开启时刻，然后在该开启时刻同时开启终端设备的高速模式，例如，将自己生成的高速配置与辅网络设备生成的高速配置一起发送给终端设备，本申请并不限定。
步骤S602、辅网络设备从主网络设备接收第一指示信息。
步骤S603、辅网络设备根据该第一指示信息，为终端设备生成高速配置。
步骤S604、辅网络设备向主网络设备发送所述高速配置。
具体的，若辅网络设备采用CU-DU的分离式架构，在步骤S602至步骤S604的具体实施例中，辅网络设备中的CU可从主网络设备接收第一指示信息，然后将该第一指示信息发送给辅网络设备中的DU。进而，辅网络设备中的DU可根据该第一指示信息，为终端设备生成高速配置，然后将生成的高速配置发送给辅网络设备中的CU，由CU再将该高速配置发送给主网络设备。
步骤S605、主网络设备从辅网络设备接收辅网络设备为终端设备生成的高速配置。
在一种实施方式中，第一指示信息可以包含在辅站添加请求消息中，辅网络设备生成的高速配置可以包含在辅站添加请求确认消息中。也就是说，主网络设备可以在为终端设备配置双连接的过程中，执行上述方法，以在主网络设备与辅网络设备之间同步高速模式。如图7所示，在步骤S701中，若主网络设备决定为该终端设备配置双连接，主网络设备可以向辅网络设备发送辅站增加请求消息，该辅站增加请求消息中包括所述第一指示信息。辅网络设备在接收到该第一指示信息后可决定开启终端设备的高速模式，并为该终端设备生成相应的高速配置，进而在步骤S702中向主网络设备发送辅站增加请求确认消息，该辅站增加请求确认消息中包括辅网络设备生成的高速配置。
在另一种实施方式中，第一指示信息可以包含在辅站修改请求消息中，辅网络设备生 成的高速配置可以包含在辅站修改请求消息中。也就是说，主网络设备也可以在修改双连接配置的过程中，执行上述方法，以在主网络设备与辅网络设备之间同步高速模式。如图8所示，在步骤S801中，若主网络设备决定修改该终端设备的双连接配置，主网络设备可以向辅网络设备发送辅站修改请求消息，该辅站修改请求消息中包括所述第一指示信息。辅网络设备在接收到该第一指示信息后可决定开启终端设备的高速模式，并为该终端设备生成相应的高速配置，进而在步骤S802中向主网络设备发送辅站修改请求确认消息，该辅站修改请求确认消息中包括辅网络设备生成的高速配置。
在步骤S605之后，如图7中的步骤S703、步骤S704和步骤S705，以及图8中的步骤S803、步骤S804和步骤S805所示，主网络设备还可以向终端设备发送RRC重配置消息，该RRC重配置消息中包括辅网络设备生成的高速配置。终端设备可在完成所述高速配置后，向主网络设备发送RRC重配置完成消息，该RRC重配置完成消息用于指示终端设备已完成辅网络设备提供的高速配置。进而，主网络设备还可将接收到的RRC重配置完成消息发送给辅网络设备。
可选的，本申请实施例中，主网络设备确定要关闭终端设备的高速模式，并向辅网络设备发送第二指示信息，该第二指示信息用于指示辅网络设备关闭终端设备的高速模式，或者也可以理解为，该第二指示信息用于通知辅网络设备：主网络设备决定关闭终端设备的高速模式。主网络设备还可以为终端设备生成高速模式的释放配置，同理，辅网络设备接收到该第二指示信息后，也可以为该终端设备生成高速模式的释放配置，然后将该释放配置发送给主网络设备。如此，主网络设备可将自己生成的高速模式的释放配置和辅网络设备生成的高速模式的释放配置一起发送给终端设备，从而使得主网络设备和辅网络设备在是否关闭高速模式上也保持一致。
可选的，本申请实施例中，辅网络设备也可以确定关闭终端设备的高速模式，并向主网络设备发送第三指示信息，该第三指示信息用于指示主网络设备关闭终端设备的高速模式，或者也可以理解为，该第三指示信息用于通知主网络设备：辅网络设备决定关闭终端设备的高速模式。辅网络设备还可以为终端设备生成高速模式的释放配置，并发送给主网络设备，例如可以和上述第三指示信息一起发送给主网络设备，如此主网络设备接收到该第三指示信息后，也可以为终端设备生成高速模式的释放配置，然后将自己生成的高速模式的释放配置和辅网络设备生成的高速模式的释放配置一起发送给终端设备，从而使得主网络设备和辅网络设备在是否关闭高速模式上也保持一致。
