需要说明的是，该实施方式的实现方式可以参见图4所示的实施例的相关说明，此处不作赘述。
以下结合示例对本申请实施例进行举例说明：
需要说明的是，本申请实施例涉及的数据可以包括感知数据、QoE、MDT、SON、AI训练数据、AI模型和计算数据等，以下示例以感知数据为例进行说明。其中，感知数据的收集和传输可以有两种模式，第一种模式为感知所需的数据经数据面功能(如第一功能)进行数据收集协同和基于数据面承载进行数据传输，可以实现当有多个感知服务可使用相同的感知测量数据时，或者通信服务可与感知服务使用相同的测量数据时(例如UE上报的下行参考信号(Reference Signal，RS)的参考信号接收功率(Reference Signal Receiving Power，RSRP)等可在感知中复用)，支持UE的测量数据的复用，避免UE重复测量和重复上报；第二种模式为感知所需的数据经数据面承载进行数据传输，而不需第一功能进行数据收集协同。
示例一：数据提供功能为UE，第一功能为无线接入网节点，第一功能协调数据收集，且数据传输在核心网功能终结。
本示例以感知数据的收集和传输的第一种模式为例进行说明。对于感知数据的收集和传输的第一种模式，假设无线接入网节点和/或核心网感知功能已经确定接收感知信号和测量的UE，并且所确定的UE支持数据面。那么网络向UE发送添加/建立第一承载的第一配置信息，第一承载的配置方式可以参见前述实施例的相关说明，其中第一承载的类型为在无线接入网节点终结的控制承载。
第一功能根据感知、MDT等多个数据需求确定所需收集的数据，以及确定是否基于第二承载进行数据传输。如果确定基于第二承载进行数据传输，那么无线接入网节点向UE发送添加/建立第二承载的第二配置信息，例如，无线接入网节点可以基于第一承载向UE发送添加/建立第二承载的第二配置信息，第二承载的配置方式可以参见前述实施例的相关说明。因为数据经第一功能进行协同，第二承载的类型可以为在无线接入网节点终结的数据承 载，在该情况下，无线接入网节点可以存储收到的所有数据，并将对应感知功能所需的数据抽取后发送给核心网感知功能；或者第二承载的类型可以为在无线接入网节点处理后并转发的数据承载，在该情况下，无线接入网节点可以对不同时间/位置的多个感知测量数据进行滤波等处理，以产生更少量的感知测量数据和/或跟高精度的感知测量数据，然后将处理后的数据转发至核心网感知功能。示例性的，本示例中，在层二子层包括MAC的情况下，UE、RAN和核心网(Core Network，CN)的协议栈可以如图8所示。
如果确定不基于第二承载进行数据传输，那么第一承载的类型可以是控制和数据承载，也即可以通过第一承载传输感知数据。
具体的，无线接入网节点可以基于第一承载向UE发送数据收集请求(或称为数据收集配置或测量配置等)，所述数据收集请求由第一功能确定。其中，所述数据收集请求可以包括如下至少一项：
测量对象(Measurement Object)，用于指定要测量的内容；可选地，上述测量对象还可以包括小区特有的偏移量，要忽略的黑名单小区和考虑测量的白名单小区；
上报配置(Reporting Configuration)，用于指定报告应该如何完成，这可以是周期性的，也可以是事件触发的；
测量ID(Measurement ID)，用于标识如何报告特定对象的测量值；一个测量对象可以有多个报告配置，一个报告配置可以应用于多个测量对象。每个测量对象到上报配置的关联都使用一个惟一的ID。当UE发送一个测量报告(MeasurementReport)消息时，该MeasurementReport消息中会包含一个ID和相关的度量(即各个测量量的测量结果)；
测量间隔(Measurement Gap)，用于指示UE可用于执行测量的周期等。
其中，在上报配置中可以配置第二承载的ID，UE根据所配置的第二承载的ID，基于第二承载进行感知数据上报，无线接入网节点接收到第二承载的数据后根据第二承载的类型，将该数据转发给核心网感知功能(Sensing Function，SF)。
示例二：数据提供功能为UE，第一功能为无线接入网节点，第一功能配置数据转发信息，且数据传输在核心网功能终结。
本示例以感知数据的收集和传输的第二种模式为例进行说明。对于感知数据的收集和传输的第二种模式，假设无线接入网节点和/或核心网感知功能已经确定接收感知信号和测量的UE，并且所确定的UE支持数据面。那么无线接入网节点向UE发送添加/建立第一承载的配置信息，第一承载的配置方式可以参见前述实施例的相关说明，其中第一承载的类型为在无线接入网节点终结的控制承载。
第一功能接收感知配置信息，例如，第一功能从核心网感知功能接收感知配置信息，并可基于第一承载将所述感知配置信息转发给UE的感知服务功能。其中，感知配置信息包含目标指示信息，用于指示第一协议层转发感知配置信息以及需第一协议层透明转发的感知配置信息(如果为了防止第一协议层解析，上述感知配置信息可采用加密方式传输)。可选 地，所述感知配置信息的SDU包含感知服务功能ID或可用于确定合适的感知服务功能的信息。其中感知服务功能ID用于无线接入网节点根据感知服务功能ID将所接收的数据转发给所指示的感知服务功能。上述用于确定合适的感知服务功能的信息可以是感知服务类型(如雨量监测、测速等)、地理位置信息等，无线接入网节点根据所获得的感知服务类型、地理位置信息、感知服务功能的负载信息等确定合适的感知服务功能，并将所接收的数据转发给所确定的感知服务功能。
第一功能确定是否基于第二承载进行数据传输，如果确定基于第二承载进行数据传输，那么无线接入网节点向UE发送添加/建立第二承载的第二配置信息，第二承载的配置方式可以参见前述实施例的相关说明。因为数据最终传输至核心网感知功能，第二承载的类型为在无线接入网节点转发的数据承载，或者在无线接入网节点处理后转发的数据承载。对于后者无线接入网节点可以对不同时间/位置的多个感知测量数据进行滤波等处理，以产生更少量的感知测量数据和/或跟高精度的感知测量数据，然后将处理后的数据转发至核心网感知功能。示例性的，在本示例中，在层二子层包括MAC的情况下，UE、RAN和CN的协议栈可以如图9所示，其中，如果RAN和CN之间采用服务化接口，那么无线接入网可以通过数据服务的方式向核心网功能提供数据。核心网数据功能、核心网感知功能和核心网AI功能可以采用服务化接口方案，服务化接口方案需支持高效的数据传输(如文件传输协议(File Transfer Protocol，FTP)或卡夫卡等方式)。
如果确定不基于第二承载进行数据传输，那么第一承载的类型可以是控制和数据承载。
需要说明的是，对于UE上报配置，有两种方式。一种方式是在上述第一协议层转发的感知配置信息的SDU配置第二承载的ID，从而UE根据所配置的第二承载的ID，基于第二承载进行感知数据上报，无线接入网节点接收到第二承载的数据后根据第二承载的类型，将该数据转发核心网感知功能。另一种方式与示例一的方式相同，即无线接入网节点向UE发送添加/建立第一承载的第一配置信息，其中，第一承载的类型为在无线接入网终结的控制承载，无线接入网节点基于终结在第一协议层的第一承载发送数据收集请求给UE，所述数据收集请求至少包括第二承载的ID，这样也可以实现UE根据所配置的第二承载的ID，基于第二承载进行感知数据上报，无线接入网节点接收到第二承载的数据后根据第二承载的类型，将该数据转发核心网感知功能。
示例三：数据提供功能为UE，第一功能为为无线接入网节点，数据传输在无线接入网节点终结。
本示例与示例一或示例二的主要差别在于，如果确定基于第二承载进行数据传输，那么无线接入网节点向UE发送添加/建立第二承载的第二配置信息。因为数据最终传输至无线接入网感知功能，因此，第二承载的类型是在无线接入网节点终结。如果，无线接入网内部采用CU-CP、集中单元用户面(Centralized Unit-User Plane，CU-UP)和集中单元数据面(Centralized Unit–Data Plane，CU-DP)的功能方案，那么第二类承载的类型也可以进一步 细分为在数据面功能终结、数据面功能转发、以及数据面功能处理后转发。其中，上述在数据面功能终结的承载类型适用于前述第一种模式，在该情况下，示例性的，在层二子层包括MAC的情况下，UE、RAN和CN的协议栈可以如图10所示。对于上述数据面功能转发以及数据面功能处理后转发的承载类型，数据面功能将所接收的数据转发至CU-CP或CU-UP等无线接入网功能，示例性的，在层二子层包括PDCP、RLC、MAC和PHY的情况下，UE、RAN和CN的协议栈可以如图11所示
如果确定不基于第二承载进行数据传输，那么第一承载的类型可以是控制和数据承载。
