具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、第五代(5th generation，5G)系统中的新无线(new radio，NR)或未来可能出现的其他的通信系统。
图1是应用于本申请的一个通信系统的示意图。如图1所示，该系统包括核心网设备、CU和DU，CU可以分为CU-UP和CU-CP。CU-UP也可以称为集中单元的用户面实体或用户面实体。CU-CP也可以称为集中单元的控制面实体或控制面实体。核心网设备和CU(如CU-UP和/或CU-CP)之间可以进行通信，例如，CU-CP可以代表接入网设备通过Ng接口和核心网设备连接。CU-UP和CU-CP之间可以进行通信，例如，可以通过E1接口通信。CU-UP和CU-CP与DU之间可以进行通信，例如，CU-CP可以通过F1-C(控制面)和DU连接，CU-UP通过F1-U(用户面)和DU连接。
核心网设备在不同的系统对应不同的网元。比如，在4G网络中核心网设备可以对应移动管理功能(mobility management entity，MME)和/或服务网关(serving gateway，S-GW)；在5G网络中可以对应接入和移动管理功能(access and mobility management function，AMF)、会话管理功能(session management function，SMF)或者用户面功能(user plane function，UPF)等。
CU和DU是对接入网设备从逻辑功能角度的划分。接入网设备例如可以是基站(base station)、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、5G移动通信系统中的下一代基站(next generation NodeB，gNB)、未来移动通信系统中的基站或WiFi系统中的接入节点等。CU和DU在物理上可以是分离的也可以部署在一起。多个DU可以共用一个CU，一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通过接口相连，例如可以是F1接口。CU和DU可以根据无线网络的协议层划分，例如其中一种可能的划分方式是：CU用于执行无线资源控制(radio resource control，RRC)层、业务数据适配协议(service data adaptation protocol，SDAP)层以及分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，而DU用于执行 无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层以及物理(physical)层等的功能。可以理解，上述划分仅仅是一种举例，CU和DU也可以按照其他的方式进行划分。例如可以将CU或者DU划分为具有更多协议层的功能。例如，CU或DU还可以划分为具有协议层的部分处理功能。在一种可能的实现方式中，将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种可能的实现方式中，还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。在又一种可能的实现方式中，CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能，也可以将射频功能拉远设置。应理解，CU和DU的功能可以在具体实现中可以根据需要设置，本申请实施例对此不作任何限定。
CU的功能可以由一个实体来实现也可以由不同的实体实现。在一种方式中，CU的功能可以进一步切分为CP功能和UP功能，即，CU可以分为CU-UP和CU-CP。CU-CP和CU-UP可以分别由一个物理设备来实现，或者二者可以部署在同一物理设备中。CU-CP和CU-UP可以与DU相耦合，共同完成接入网设备的功能。一种可能的方式中，CU-CP负责控制面功能，主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密、完整性保护以及数据传输等。CU-UP负责用户面功能，主要包含SDAP和PDCP-U。其中SDAP主要负责将核心网设备的数据进行处理并将数据流(flow)映射到承载。PDCP-U主要负责数据面的加解密、完整性保护、头压缩、序列号维护以及数据传输等。还有一种可能的实现是PDCP-C也在CU-UP。
应理解，图1所示的协议层的划分方式仅是一个示例性的方式，并不应对本申请构成任何限定。另外，图1所示的系统还可以包括图中未示出的终端设备。终端设备可以指用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
在无线网络中，一个终端设备可能和多个接入网设备通信，即双连接(dual connectivity，DC)，也称为多无线双连接(Multi-Radio dual connectivity，MR-DC)。这多个接入网设备可能是属于同一制式的接入网设备(比如都是4G接入网设备，或者都是5G接入网设备)，也可能是不同机制的接入网设备(比如一个是第四代4G接入网设备，一个是第五代5G接入网设备)。网络侧可以利用多个接入网设备的资源为该终端设备提供通信服务，从而为终端设备提供高速率传输。DC中与核心网设备有控制面信邻交互的接入网设备称为主节点(master node，MN)，其他接入网设备称为辅节点(secondary nose，SN)。需要说明的是，MR-DC中MN和SN可以是前面所述接入网设备的各种形式和结 构。可选地，MN和SN使用相同的CU而DU不同，或使用相同的DU而CU不同。
下面对本申请提供的方法进行说明。需要说明的是，下文中描述的CU-CP和CU-UP可以由一个实体实现，也可以由不同的实体实现。
图2是本申请提供的一种通信方法的示意性流程图。下面结合图2对方法200的各步骤进行说明。
S210，第一网络节点获取业务的第一业务特征，第一网络节点为CU-UP。
示例性的，第一业务特征可以包括下述中的一项或多项：该业务是否为周期业务、该业务对应的业务包大小、该业务对应的业务模型或者该业务的调度时间、在该业务为周期业务的情况下该业务对应的周期。
所述业务模型例如可以是下述其中之一：只有单上行、只有单下行、单上行之后跟着单下行、单上行之后跟着多下行、多上行之后跟着单下行。其中，这里的单/多指的是数据包个数。
只有单上行是指该业务只有上行数据包，并且每次只发送该业务的一个上行数据包。只有单下行的含义类似(即指该业务只有下行数据包，并且每次只发送该业务的一个下行数据包)。单上行之后跟着单下行是指该业务即有上行数据包又有下行数据包，并且每次发送该业务的一个上行数据包之后仅接着发送该业务的一个下行数据包。单上行之后跟着多下行是指该业务即有上行数据包又有下行数据包，并且每次发送该业务的一个上行数据包之后仅接着发送该业务的多个下行数据包。多上行之后跟着单下行的含义类似。
所述业务模型例如还可以是下述其中之一：只有上行、只有下行、上下行都有。只有上行是指该业务只有上行数据包。只有下行是指该业务只有下行数据包。上下行都有是指该业务即有上行数据包，也有下行数据包。
所述调度时间例如可以是每周的调度时间或者每天的调度时间等。
示例性的，第一业务特征对应的粒度可以是下述中的任一种：PDU会话、终端设备、QoS流、DRB或者切片。
或者，可以理解为，第一业务特征为特定的PDU会话、终端设备、QoS流、DRB或者切片对应的业务特征，该特定的PDU会话、终端设备、QoS流、DRB或者切片对应所述业务。举例来说，第一业务特征可以是特定的QoS流，如QoS流#1，对应的业务特征，其中QoS流#1对应所述业务。第一业务特征可以是特定的DRB，如DRB#1，对应的业务特征，其中DRB中承载的QoS流对应所述业务。
应理解，针对同一业务，不同粒度对应的业务特征可能不同。比如，QoS流#1对应DRB#1，二者对应同一业务，但QoS流#1对应的业务特征和DRB#1对应的业务特征可能相同，也可能不同。
还应理解，在S210中，第一网络节点可以获取一个或多个业务中每个业务的一个或多个业务特征，每个业务的一个或多个业务特征对应的粒度可能相同，也可能不同，本申请对此不作限定。例如，在S210中，第一网络节点可以获取业务#1的一个或多个业务特征，以及获取业务#2的一个或多个业务特征。其中，业务#1的一个或多个业务特征例如可以是切片#1的业务特征和切片#2的业务特征，业务#2的一个或多个业务特征例如可以是QoS流#1和QoS流#2的业务特征。
在S210中，CU-UP可以通过多种方式获取第一业务特征。下面举例进行说明。
方式一
CU-UP可以根据算法信息，确定第一业务特征。
其中，该算法信息可以包括第一算法和/或第一算法对应的参数信息。示例性的，该算法信息可以是核心网设备发送给CU-UP的，比如核心网设备直接发送给CU-UP，或者核心网设备先发送给CU-CP，CU-CP再发送给CU-UP。或者，该算法信息也可以是其他网元(例如，网管)发送给CU-UP的。
举例来说，CU-UP可以具有业务特征预测功能，比如CU-UP可以根据预测算法和/或预测算法对应的参数信息(或称为预测模型)以及接收到的数据包预测业务特征。比如，CU-UP可以基于一定时间段内或当前接收到的QoS流#1的数据包，通过第一算法(即，预测算法的一例)和/或第一算法对应的参数信息，来预测QoS流#1的业务特征(第一业务特征的一例)。如，若CU-UP在一段时间内只在QoS流#1上接收到上行数据包，则认为QoS流#1对应的业务的业务模型为只有单上行。示例性的，所述预测算法可以是AI算法，如监督学习算法中的某些具体算法(比如决策树、朴素贝叶斯分类、最小二乘法、支持向量机等)、无监督学习算法中的某些具体算法(比如聚类算法等)或者强化学习中的某些具体算法。应理解，第一算法可以是上述算法中任一种。
可选地，CU-UP还可以向核心网设备发送第二算法和/或第二算法对应的参数信息。第一算法和第二算法可以相同，也可以不同。第二算法例如可以是上文所述的任一种算法，如朴素贝叶斯分类。示例性的，第二算法和/或第二算法对应的参数信息可以由CU-UP直接发送给核心网设备。或者，第二算法和/或第二算法对应的参数信息也可以由CU-UP先发送给CU-CP，CU-CP再发送给核心网设备。
举例来说，CU-UP在预测业务特征的过程中，也可以对预测算法和/或预测算法对应的参数信息进行调整，并且可以将调整后的预测算法(如，第二算法)和/或调整后的预测算法对应的参数信息(如，第二算法对应的参数信息)发送给核心网设备。这样，CU-UP切换之后，或者终端设备进入到无线资源控制(radio resource control，RRC)空闲(RRC_idle)态，再由RRC_idle态进入RRC连接(RRC_connected)态时，核心网设备可以把这些信息发送给与该终端设备重新建立连接的CU-UP(下文中记作：目标CU-UP)。比如，核心网设备可以将调整后的预测算法(如，第二算法)和/或调整后的预测算法对应的参数信息直接发送给目标CU-UP，或者先发送给与该目标CU-UP连接的CU-CP(下文中记作：目标CU-CP)，再由目标CU-CP发送给目标CU-UP。同时应理解，目标CU-UP和上文中的CU-UP可能是同一CU-UP，也可能不是。CU-UP接收到核心网设备发送的信息后，可以继续利用这些信息进行预测。
方式二
CU-UP可以根据辅助信息，确定第一业务特征。
举例来说，CU-UP具有业务特征预测功能，CU-UP可以在辅助信息的基础上进行更精细的预测，比如更准确的预测等。示例性的，辅助信息可以包括该业务的一个或多个业务特征，业务特征中的参数和第一业务特征中的参数类型可以相同。也就是说，CU-UP可以基于该业务之前的业务特征，确定该业务当前的业务特征。
辅助信息可以是核心网设备或者网管发送的。比如，核心网设备或者网管可以直接向CU-UP发送辅助信息，或者核心网设备或者网管可以将辅助信息发送给CU-CP，CU-CP 再将辅助信息转发给CU-UP。示例性的，所述辅助信息可以是终端设备上一次所接入的CU-UP所确定并发送给核心网设备的。
辅助信息还可以是CU-UP从本地或者其他CU-UP处获取的。比如切换场景中，源接入网设备把辅助信息发送给目标接入网设备，例如，在切换请求消息中携带辅助信息。又比如在MR-DC场景中，MN把辅助信息发送给SN，例如在增加SN请求消息或者修改SN请求消息中携带辅助信息。这里的源接入网设备和目标接入网设备，或者源MN和SN，可以对应同一个CU-UP，也可以对应不同的CU-UP。另外，上述第一算法和第一算法对应的参数信息也可以通过这里所描述的方式获取。
方式三
CU-UP可以从本地或者其他CU-UP处获取第一业务特征。
比如切换场景中，源接入网设备可以将第一业务特征发送给目标接入网设备，例如，在切换请求消息中携带第一业务特征。又比如在MR-DC场景中，MN可以将第一业务特征发送给SN，例如在增加SN请求消息或者修改SN请求消息中携带第一业务特征。这里的源接入网设备和目标接入网设备，或者源MN和SN，可以对应同一个CU-UP，也可以对应不同的CU-UP。
应理解，CU-UP可以结合上述三种方式或三种方式中的任意两种方式，确定第一业务特征。
S220，第一网络节点向第二网络节点发送第一业务特征，第二网络节点为CU-CP。
CU-CP接收到第一业务特征后，有两种处理方式，下面分别进行说明。
方式一：
S230，CU-CP向第三网络节点发送第一业务特征。其中，方法200中的第三网络节点为DU。
比如，CU-CP在接收到第一业务特征后，可以直接将第一业务特征转发给DU。
或者，若CU-CP确定第一业务特征对应的粒度和CU-CP需要发送给DU的业务特征所对应的粒度相同，则CU-CP可以将第一业务特征发送给DU。比如，第一业务特征为DRB#1的业务特征，CU-CP需要提供给DU的业务特征的粒度也是DRB，则CU-CP可以向DU发送DRB#1的业务特征。
方式二：
S240，CU-CP根据第一业务特征，确定该业务的第二业务特征，第一业务特征和第二业务特征对应的粒度不同。
可选地，第二业务特征对应的粒度可以是下述中的任一种：PDU会话、终端设备、QoS流、DRB或者切片。
S250，CU-CP向所述DU发送第二业务特征。
举例来说，若CU-CP确定第一业务特征对应的粒度和CU-CP需要发送给DU的业务特征所对应的粒度不同，则CU-CP可以根据第一业务特征，确定该业务的第二业务特征。比如，第一业务特征为QoS流#1的业务特征，而CU-CP需要提供给DU的业务特征的粒度为DRB，则CU-CP可以根据QoS流#1的业务特征，确定QoS流#1对应的DRB#1的业务特征(即，第二业务特征的一例)。如，CU-CP可以将QoS流#1的业务特征，作为DRB#1的业务特征提供给DU，或者，CU-CP可以结合QoS流#1的业务特征以及DRB#1 对应的其他一个或多个QoS流的业务特征，确定DRB#1的业务特征，并将所确定的DRB#1的业务特征发送给DU。
DU获取到第一业务特征或第二业务特征后，可以进行业务调度或配置。比如，DU可以根据第一业务特征或第二业务特征，进行不同的调度或配置。比如，DU获知业务为周期业务，则DU可以根据业务对应的周期来调度终端设备。又比如DU可以根据业务对应的周期来配置半静态调度(semi-presistent scheduling，SPS)周期或非连续接收(discontinuous reception，DRX)的配置信息。又比如，DU根据业务对应的业务包大小或/和业务的周期等来选择是否配置载波聚合功能。
根据本申请提供的通信方法，通过由CU-UP获取业务特征，并通过CU-CP向DU发送该业务特征或者根据该业务特征所确定的另一业务特征，从而使得DU可以基于所接收到的业务特征进行业务的调度或配置。
另外，通常业务特征由核心网提供给接入网设备，而核心网提供的业务特征一般都是签约的业务特征，可能与实际的业务特征不相符，从而可能导致接入网设备在进行业务调度或配置的时候无法适配业务特征。而根据本申请提供的通信方法，CU-UP可以基于实际的业务数据获取业务特征，这样获得的业务特征更符合实际传输的业务，进而DU在进行调度或配置时可以更好的适配业务。
可选地，CU-CP在接收到第一业务特征或者根据第一业务特征得到第二业务特征后，还可以将第一业务特征或第二业务特征发送给核心网设备。
这样当该终端设备下次从RRC_idle态或非激活(inactive)态回到RRC_connected时，核心网设备可以将第一业务特征或第二业务特征发送给CU-UP，CU-UP可以基于第一业务特征或第二业务特征继续预测或使用。
可选地，CU-CP接收到第一业务特征后，CU-CP也可以基于第一业务特征进行一些配置。比如，CU-CP可以根据业务对应的业务包大小或/和业务的周期等来选择是否配置双连接(dual-connectivity)。
图3是本申请提供的另一通信方法的示意性流程图。该方法300中，第一网络节点获取到第一业务特征后可以直接提供给DU。
S310，第一网络节点获取业务的第一业务特征，第一网络节点为CU-UP。
该步骤与S210相同，这里不再赘述。
S320，第一网络节点向第三网络节点发送第一业务特征，第三网络节点为DU。
即，第一网络节点可以不经过CU-CP的转发，直接将第一业务特征发送给DU。
根据本申请提供的方法，通过由CU-UP获取业务特征并提供给DU，使得DU可以基于所接收到的业务特征进行调度或配置。另外，CU-UP可以基于实际的业务数据获取业务特征，这样获得的业务特征更符合实际传输的业务，进而DU在进行调度或配置时可以更好的适配业务。
图4是本申请提供的另一种通信方法的示意性流程图。下面结合图4对方法400的各步骤进行说明。
S410，第一网络节点确定终端设备的第一信息，第一网络节点为CU-CP。
S420，CU-CP向第二网络节点发送第一信息，第二网络节点为DU。
示例性的，第一信息可以包括下述中的一项或多项：该终端设备的移动信息、该终端 设备的电池信息或者该终端设备的耗电信息。
该终端设备的移动信息可以指示该终端设备是否处于移动状态或者是否静止。可选地，该终端设备的移动信息还可以包括该终端设备在处于移动状态时的移动速率等级，比如高速、中速或正常速度。可选地，该终端设备的移动信息可以包括波束(beam)级别的移动历史信息。波束级别的移动历史信息用于指示该终端设备所经历的波束以及在所经历的波束上所处的时间。终端设备所经历的波束可以理解为为终端设备提供服务的波束。可选的，这里的波束可以是指同步信号和PBCH块(synchronization signal and pbch block，SSB)或信道状态信息参考信号(channel state information reference signal，CSI-RS)
该终端设备的电池信息可以指示该终端设备的电池是否可充电，或者指示该终端设备是否连接了电源。
该终端设备的耗电信息可以指示该终端设备的电池的耗电情况，如目标剩余电量等。
在S410中，CU-CP可以根据多种方式确定第一信息。下面举例进行说明。
方式一
CU-CP可以根据算法信息，确定第一信息。
其中，算法信息可以包括第一算法和/或第一算法对应的参数信息。示例性的，所述算法信息可以是核心网设备发送的，也可以是其他网元(例如，网管)发送的。
举例来说，CU-CP具有预测功能，比如CU-UP可以根据预测算法和/或预测算法对应的参数信息(或称为预测模型)预测第一信息。这里的预测算法可以是方法200中描述的任一种算法。应理解，第一算法可以是任一种预测算法。
可选地，CU-CP还可以向核心网设备发送第二算法和/或第二算法对应的参数信息。第一算法和第二算法可以相同，也可以不同。第二算法例如可以是监督学习算法中的某些具体算法或者无监督学习算法中的某些具体算法等。
举例来说，CU-CP在预测过程中，也可以对预测算法和/或预测算法对应的参数信息进行调整，并且可以将调整后的预测算法(如，第二算法)和/或调整后的预测算法对应的参数信息(如，第二算法对应的参数信息)发送给核心网设备。这样，CU-CP切换之后，或者终端设备进入到RRC_idle态，再由RRC_idle态进入RRC_connected态时，核心网设备可以将这些信息发送给与该终端设备重新建立连接的CU-CP(下文中记作：目标CU-CP)。应理解，目标CU-CP和上文中的CU-CP可能是同一CU-CP，也可能不是。CU-CP接收到核心网设备发送的信息后，可以继续利用这些信息进行预测。
基于上段描述可以理解，第一算法和/或第一算法对应的参数信息可以是某一CU-CP在切换前或者终端设备进入到RRC空闲态之前发送给核心网设备的。
方式二
CU-CP可以根据辅助信息，确定第一信息。
举例来说，CU-CP具有预测功能，CU-CP可以在第一信息的基础上进行更精细的预测，比如更准确的预测等。比如，辅助信息中的参数可以和第一信息中的参数类型相同，但辅助信息可以和第一信息的粒度不同，如辅助信息是小区粒度的，第一信息为波束粒度的，即CU-CP可以基于小区粒度的信息预测波束粒度的相应的信息。
辅助信息可以是核心网设备或者网管发送的。示例性的，所述辅助信息可以是终端设备上一次所接入的CU-CP所确定并发送给核心网设备的。
辅助信息还可以是CU-CP从本地或者其他CU-CP处获取的。比如切换场景中，源接入网设备把辅助信息发送给目标接入网设备，例如，在切换请求消息中携带辅助信息。又比如在MR-DC场景中，MN把辅助信息发送给SN，例如在增加SN请求消息或者修改SN请求消息中携带辅助信息。这里的源接入网设备和目标接入网设备，或者源MN和SN，可以对应同一个CU-CP，也可以对应不同的CU-CP。另外，第一算法和第一算法对应的参数信息也可以通过这里所描述的方式获取。
可选地，上述两种确定终端设备的第一信息的方式可以结合。即，终端设备可以根据第一算法和/或第一算法对应的参数信息，以及辅助信息，确定终端设备的第一信息。
可选地，本申请中，CU-CP也可以利用第一信息进行本地配置，如移动测量的配置。
在S420中，DU可以接收到第一信息。在DU接收到第一信息后，可以根据第一信息，为该终端设备配置无线参数。
示例性的，无线参数可以包括下述中的一项或多项：非连续接收(discontinuous reception，DRX)的配置信息、波束配置信息、数据不激活定时器长度(当终端设备在该定时器内没有收到或发送任何MAC服务数据单元(service data unit,SDU)时，终端设备会释放和网络侧的RRC连接，并进入RRC空闲态)、是否配置载波聚合、终端设备可以使用的带宽、以及终端设备可以使用的最大多入多出(multiple input multiple output,MIMO)层数等。
可选地，该方法还可以包括：S430，CU-CP向核心网设备发送所述第一信息。
CU-CP可以把第一信息发送给核心网设备，这样当该终端设备下次从RRC_idle态或非激活(inactive)态回到RRC_connected时，核心网设备可以把第一信息发送给CU-CP，CU-CP可以基于第一信息继续预测或使用。
综上，本申请提供的方法，CU-UP可以确定表征终端设备的某些特征的第一信息，并且CU-UP可以向DU发送第一信息，从而DU可以根据第一信息为终端设备配置合适的无线参数，从而更好的为终端设备服务。
图5是本申请提供的另一通信方法的示意性流程图。下面结合图5对方法500的各步骤进行说明。
S510，第二网络节点确定终端设备的配置信息。第二网络节点为DU。
S520，DU通过第一网络节点，向核心网设备发送该配置信息。第一网络节点为CU-CP。
示例性的，该配置信息包括下述中的一种或多种：半静态调度配置、多输入多输出MIMO配置、信道状态信息参考信号CSI-RS配置或者探测参考信号SRS配置。
举例来说，半静态调度配置可以包括下述中的一项或多项：半静态调度周期、半静态调度对应的混合自动重传请求(hybrid automatic repeat reQuest，HARQ)进程号、半静态调度对应的调制编码表格、下行半静态调度对应的PUCCH资源。
CSI-RS配置可以包括下述中的一项或多项：频域位置、端口数目、时域位置、码域类型。
SRS配置可以包括下述中的一项或多项：周期还是非周期、端口数目、资源位置等。
MIMO配置可以包括MIMO的流数等。
在一种方式中，在S510中，DU可以根据算法信息，确定所述配置信息。算法信息可以包括第一算法和/或第一算法对应的参数信息。示例性的，所述算法信息可以是核心 网设备发送的，也可以是其他网元(例如，网管)发送的。
举例来说，DU具有预测功能，比如DU可以根据预测算法和/或预测算法对应的参数信息(或称为预测模型)预测所述配置信息。这里的预测算法可以是方法200中描述的任一种算法。应理解，第一算法可以是任一种预测算法。
可选地，DU还可以向CU-CP发送第二算法和/或第二算法对应的参数信息。进一步地，CU-CP可以将第二算法和/或第二算法对应的参数信息发送给核心网设备。第一算法和第二算法可以相同，也可以不同。第二算法例如可以是监督学习算法中的某些具体算法或者无监督学习算法中的某些具体算法等。
举例来说，DU在预测过程中，也可以对预测算法和/或预测算法对应的参数信息进行调整，并且可以将调整后的预测算法(如，第二算法)和/或调整后的预测算法对应的参数信息(如，第二算法对应的参数信息)发送给CU-CP。这样，当终端设备切换到一个新的DU时，CU-CP可以把这些信息发送给新的DU，新的DU可以利用这些信息给UE配置相关信息。
另一种方式中，在S510中，DU可以根据辅助信息，确定所述配置信息。
示例性的，辅助信息中的参数可以和终端设备的配置信息中的参数的类型相同。
辅助信息可以是核心网设备或者网管发送的。示例性的，所述辅助信息可以是终端设备上一次所接入的DU所确定并发送给核心网设备的。
辅助信息还可以是DU从本地或者其他DU处获取的。比如切换场景中，源接入网设备把辅助信息发送给目标接入网设备。例如，在切换请求消息中携带辅助信息。又比如在MR-DC场景中，MN把辅助信息发送给SN。例如在增加SN请求消息或者修改SN请求消息中携带辅助信息。这里的源接入网设备和目标接入网设备，或者源MN和SN，可以对应同一个DU，也可以对应不同的DU。另外，第一算法和第一算法对应的参数信息也可以通过这里所描述的方式获取。
可选地，上述两种确定所述配置信息的方式可以结合。即，终端设备可以根据第一算法和/或第一算法对应的参数信息，以及辅助信息，确定所述配置信息。
在S520中，DU先将所述配置信息发送给CU-CP，CU-CP再将所述配置信息发送给核心网设备。
这样，当该终端设备下次从RRC_idle态或inactiv态回到RRC_connected时，核心网设备可以将所述配置信息发送给对应的DU，对应的DU可以基于所述配置信息继续预测或使用。
本申请提供的方法中，DU可以将终端设备的配置信息发送给核心网设备，从而便于后续的DU进行调度或配置无线参数。
图6是本申请提供的另一通信方法的示意性流程图。下面结合图6对方法600的各步骤进行说明。
S610，核心网设备确定业务的第一业务特征。
示例性的，第一业务特征可以包括下述中的一项或多项：该业务是否为周期业务、该业务对应的业务包大小、该业务对应的业务模型或者该业务的调度时间、业务的时延要求、在该业务为周期业务的情况下该业务对应的周期。
可选地，时延要求可以区分上下行。即，如果该业务为上行业务，则该时延要求为上 行时延要求。如果该业务为下行业务，则该时延要求为下行时延要求。如果该业务即包括上行又包括下行业务，则时延要求包括上行时延要求和下行时延要求。
应理解，业务模型和调度时间的含义可以参照方法200中的说明。
示例性的，第一业务特征对应的粒度可以是下述中的任一种：PDU会话、QoS流、DRB或者切片。
或者，可以理解为，第一业务特征为特定的PDU会话、QoS流、DRB或者切片对应的业务特征，该特定的PDU会话、QoS流、DRB或者切片对应所述业务。举例来说，第一业务特征可以是特定的QoS流，如QoS流#1，对应的业务特征，其中QoS流#1对应所述业务。
应理解，针对同一业务，不同粒度对应的业务特征可能不同。比如，QoS流#1对应DRB#1，二者对应同一业务，但QoS流#1对应的业务特征和DRB#1对应的业务特征可能相同，也可能不同。
还应理解，在S610中，第一网络节点可以获取一个或多个业务中每个业务的一个或多个业务特征，每个业务的一个或多个业务特征对应的粒度可能相同，也可能不同，本申请对此不作限定。例如，在S610中，第一网络节点可以获取业务#1的一个或多个业务特征，以及获取业务#2的一个或多个业务特征。其中，业务#1的一个或多个业务特征例如可以是切片#1的业务特征和切片#2的业务特征，业务#2的一个或多个业务特征例如可以是QoS流#1和QoS流#2的业务特征。
S620，核心网设备向第一网络节点发送第一业务特征，第一网络节点为CU-CP。
S630，CU-CP向第二网络节点发送第二业务特征，第二网络节点为CU-UP或DU。
第一业务特征和第二业务特征可以相同，也可以不同。示例性的，第二业务特征可以是PDU会话、QoS流、DRB或者切片。
举例来说，CU-CP在接收到第一业务特征后，可以直接将第一业务特征转发给第二网络节点。
或者，若CU-CP确定第一业务特征对应的粒度和CU-CP需要发送给第二网络节的业务特征所对应的粒度相同，则CU-CP可以将第一业务特征发送给第二网络节。比如，第一业务特征为DRB#1的业务特征，CU-CP需要提供给第二网络节的业务特征的粒度也是DRB，则CU-CP可以向第二网络节发送DRB#1的业务特征。
或者，若CU-CP确定第一业务特征对应的粒度和CU-CP需要发送给第二网络节点的业务特征所对应的粒度不同，则CU-CP可以根据第一业务特征，确定该业务的第二业务特征。比如，第一业务特征为QoS流#1的业务特征，而CU-CP需要提供给第二网络节点的业务特征的粒度为DRB，则CU-CP可以根据QoS流#1的业务特征，确定QoS流#1对应的DRB#1的业务特征(即，第二业务特征的一例)。如，CU-CP可以将QoS流#1的业务特征，作为DRB#1的业务特征提供给第二网络节点，或者，CU-CP可以结合QoS流#1的业务特征以及DRB#1对应的其他一个或多个QoS流的业务特征，确定DRB#1的业务特征，并将所确定的DRB#1的业务特征发送给第二网络节点。又如，对于业务的时延要求，假设第一业务特征中的业务的时延要求为第一粒度，CU-CP可以将第一粒度的业务对时延的要求大小分解到各个实体(比如CU-UP侧需要保证的时延，F1-U口需要保证的时延，DU侧需要保证的时延,终端设备侧需要保证的时延)，CU-CP将对各个实体的时延要 求通知给CU-UP和DU。比如对于下行而言，CU-CP可以将对下行的时延要求分解到CU-UP、F1口时延、DU侧的时延和终端设备侧的时延。CU-CP将对CU-UP和F1口时延要求通知给CU-CP，将对DU侧的时延要求发送给DU。从而CU-UP和DU可以根据对应的时延要求调整对应的业务的处理，从而满足对应的时延要求。
当前技术中，核心网设备可以向接入网设备提供终端设备粒度的业务特征，而本申请提供的方法，核心网设备可以向CU-UP或DU发送更小粒度的业务特征，从而CU-UP或DU可以根据这些更小粒度的业务特征进行更准确的调度和资源分配，从而更好地为终端设备提供通信服务。
