图2A是根据本公开实施例示出的协议确定方法的交互示意图。如图2A所示，本公开实施例涉及协议确定方法，应用于第一设备和第二设备，可选地，第一设备为终端，第二设备为接入网设备，或者，第一设备为接入网设备，第二设备为终端，上述方法包括：
步骤S2101，终端基于第一业务向接入网设备发送第一请求，该第一请求用于请求建立终端与接入网设备之间的通道。
在本公开实施例中，终端会获知第一业务，进而通过第一业务判断是否向接入网设备发送建立请求。在一些实施例中，该通道用于终端与接入网设备之间进行数据传输和/或信令传输。
在一些实施例中，本公开实施例实际上是终端基于第一业务决定建立终端与接入网设备之间的通道，还是建立其他通道。其中，其他通道例如为终端需要通过接入网设备与核心网设备建立相关通道，或者，经由通过接入网设备、核心网设备与第三方服务器，例如数据网(Data Network，DN)设备，建立相关通道。或者，本公开实施例也可以理解为终端基于第一业务对建立的通道进行决策，进而向接入网设备请求建立对应的通道，接入网设备接收到该第一请求后，直接建立该第一请求所请求建立的通道即可，无需接入网设备再进行决策。
在一些实施例中，终端基于第一业务的类型确定是否请求建立终端与接入网设备之间的通道，进而确定是否发送第一请求。可选地，若终端确定第一业务的类型为预设类型，则发送第一请求来请求接入网设备建立终端与接入网设备之间的通道。在一些实施例中，该第一请求用于请求建立终端与接入网设备之间的通道。该终端与接入网设备之间的通道是指终端与接入网设备之间进行数据传输的通道。在一些实施例中，该通道也可以理解为数据仅在终端与接入网设备之间传输，而不同再经由接入网设备转发给核心网设备。在一些实施例中，该通道也可以理解为数据仅在终端与接入网设备之间传输，不需要建立接入网设备与核心网设备之间的通道。
可选地，若终端确定第一业务的类型不是预设类型，则说明无需建立终端与接入网设备之间的通道，无需发送第一请求。或者，确定第一业务的类型不是预设类型，则建立终端与接入网设备之间的其他通道。这里的其他通道例如为终端需要通过接入网设备与核心网设备建立相关通道，或者，经由通过接入网设备、核心网设备与第三方服务器，例如数据网(Data Network，DN)设备，建立相关通道。
在一些实施例中，接入网设备接收终端发送的第一请求。在一些实施例中，终端发送第一请求。对应的，接入网设备接收第一请求。
可选地，该第一请求包括第一指示，该第一指示用于直接指示建立终端与接入网设备之间的通道。在本公开实施例中，由终端确定建立的通道的类型，通过该第一请求直接告知接入网设备需要建立与终端之间的通道。
在本公开实施例中，通过在第一请求中携带第一指示的方式直接指示接入网设备建立终端与接入网设备之间的通道，保证建立通道的准确性。
在一些实施例中，预设类型为以下任一项：
(1)AI(Artificial Intelligence，人工智能)类型。
可选地，终端与接入网设备之间通过AI模型对数据进行压缩或解压缩以实现数据传输。例如，终端采用AI模型对数据进行压缩，得到压缩后的数据，向接入网设备发送压缩后的数据，接入网设备接收到压缩后的数据，对压缩后的数据进行解压缩，得到数据。又例如，接入网设备采用AI模型对数据进行压缩，得到压缩后的数据，向终端发送压缩后的数据，终端接收到压缩后的数据，对压缩后的数据进行解压缩，得到数据。其中，该AI模型由接入网设备训练，则该接入网设备为训练AI模型的数据的收集者。或者，接入网设备基于用于训练的数据对AI模型进行训练。或者，接入网设备使用该AI模型对数据进行压缩。
(2)感知类型。
可选地，接入网设备支持感知，该接入网设备可以基于无线感知功能采集大量的感知数据，比如3维点云数据，其包含了感知到的物体空间信息、速度信息等。那么接入网设备就是感知数据的来源，该感知数据如果发给终端，那么终端就是数据的用户。
(3)存储于接入网设备的业务类型。
可选地，存在业务部署在接入网设备的业务。可选地，业务包括视频等。其中，接入网设备可以理解为数据的来源，下载该视频的终端为数据的用户。接入网设备可以采用分布式存储的方式将大量的数据预先存储在接入网设备。
(4)使用接入网设备的功能的业务类型。
可选地，存在一些业务为了使用接入网设备的存储与计算功能。例如，业务包括XR(Extended Reality，扩展现实)业务。终端可以将数据发到接入网设备利用计算的计算功能计算后再发回终端。那么接入网设备就是数据的来源，终端是数据的用户。
(5)部署于卫星的业务类型，且接入网设备部署于卫星。
在一些实施例中，第一业务例如为以下任一项：语音业务、视频业务、AI训练业务、XR业务等，本公开实施例不做限定。
