[0110] FIG. 2A is an interaction diagram of a protocol determination method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiment of the present disclosure relates to a protocol determination method applied to a first device and a second device, optionally, the first device is a terminal and the second device is an access network device, or the first device is an access network device and the second device is a terminal, and the above-mentioned method comprises:

[0111] In step S2101, the terminal sends a first request to the access network device based on the first service, where the first request is used to request to establish a channel between the terminal and the access network device.

[0112] In the embodiments of the present disclosure, the terminal learns the first service, and then determines whether to send a request to the access network device based on the first service. In some embodiments, the channel is used for data transmission and / or signaling transmission between the terminal and the access network device.

[0113] In some embodiments, the embodiments of the present disclosure actually determine whether to establish a channel between the terminal and the access network device based on the first service, or to establish other channels. For example, the terminal needs to establish a related channel through the access network device and the core network device, or establish a related channel through the access network device, the core network device and a third-party server, such as a data network (Data Network, DN) device. Alternatively, the embodiments of the present disclosure can also be understood as that the terminal determines the established channel based on the first service, and then requests the access network device to establish a corresponding channel. After receiving the first request, the access network device directly establishes the channel requested by the first request, without the need for the access network device to make a decision again.

[0114] In some embodiments, the terminal determines whether to request to establish a channel between the terminal and the access network device based on the type of the first service, and then determines whether to send the first request. Alternatively, if the terminal determines that the type of the first service is a preset type, the terminal sends the first request to request the access network device to establish a channel between the terminal and the access network device. In some embodiments, the first request is used to request to establish a channel between the terminal and the access network device. The channel between the terminal and the access network device refers to a channel for data transmission between the terminal and the access network device. In some embodiments, the channel can also be understood as that data is only transmitted between the terminal and the access network device, and then forwarded to the core network device through the access network device. In some embodiments, the channel can also be understood as that data is only transmitted between the terminal and the access network device, and there is no need to establish a channel between the access network device and the core network device.

[0115] Alternatively, if the terminal determines that the type of the first service is not the preset type, it is not necessary to establish a channel between the terminal and the access network device, and it is not necessary to send the first request. Alternatively, if the type of the first service is not the preset type, the terminal establishes other channels between the terminal and the access network device. For example, the terminal needs to establish a related channel through the access network device and the core network device, or establish a related channel through the access network device, the core network device and a third-party server, such as a data network (Data Network, DN) device.

[0116] In some embodiments, the access network device receives the first request sent by the terminal. In some embodiments, the terminal sends the first request. Correspondingly, the access network device receives the first request.

[0117] Optionally, the first request comprises a first indication, and the first indication is used to directly indicate to establish a channel between the terminal and the access network device. In the embodiments of the present disclosure, the type of the established channel is determined by the terminal, and the access network device is directly informed by the first request that the channel needs to be established between the terminal and the access network device.

[0118] In the embodiments of the present disclosure, the access network device is directly indicated to establish the channel between the terminal and the access network device by carrying the first indication in the first request, so as to ensure the accuracy of the established channel.

[0119] In some embodiments, the preset type is any one of the following:

[0120] (1) an AI (Artificial Intelligence) type.

[0121] Optionally, the data is compressed or decompressed by an AI model between the terminal and the access network device to realize data transmission. For example, the terminal compresses the data by using an AI model to obtain compressed data, and sends the compressed data to the access network device. The access network device receives the compressed data, decompresses the compressed data, and obtains the data. For another example, the access network device compresses the data by using an AI model to obtain compressed data, and sends the compressed data to the terminal. The terminal receives the compressed data, decompresses the compressed data, and obtains the data. The AI model is trained by the access network device, and the access network device is a collector of data used for training the AI model. Alternatively, the access network device trains the AI model based on the data used for training. Alternatively, the access network device uses the AI model to compress the data.

[0122] (2) a perception type.

[0123] Optionally, the access network device supports perception. The access network device can collect a large amount of perception data based on a wireless perception function, such as 3D point cloud data, which contains spatial information, speed information and the like of perceived objects. Then, the access network device is the source of the perception data, and the terminal is the user of the data if the perception data is sent to the terminal.

[0124] (3) a service type stored in the access network device.

[0125] Optionally, there is a service deployed on the access network device. Optionally, the service includes video and the like. The access network device can be understood as a data source, and the terminal downloading the video is a data user. The access network device can pre-store a large amount of data in a distributed storage manner.

[0126] (4) A service type using the function of the access network device.

[0127] Optionally, there are some services that use the storage and computing functions of the access network device. For example, the service includes an XR (Extended Reality) service. The terminal can send data to the access network device for calculation by the computing function of the access network device, and then send the data back to the terminal. The access network device is a data source, and the terminal is a data user.

[0184] Optionally, if the access network device determines that the type of the first service is not the preset type, it means that there is no need to establish the channel between the terminal and the access network device. Alternatively, if it is determined that the type of the first service is not the preset type, other channels between the terminal and the access network device are established. The other channels herein are, for example, the terminal needs to establish relevant channels with the core network device through the access network device, or relevant channels are established via the access network device, the core network device and a third-party server, such as a data network (DN) device.
