[0125] FIG. 2A is an interaction diagram of a data mapping method according to an embodiment of the present disclosure. As shown in FIG. 2A, the present embodiment relates to a data mapping method, and the method includes:

[0126] In step S2101, the terminal acquires first data of a first service.

[0127] In some embodiments, the terminal has service data to be sent, i.e., the service data needs to be sent to the access network device.

[0128] In some embodiments, the first data of the first service is only between the terminal and the access network device. Alternatively, the first data of the first service is sourced from the terminal and is destined for the access network device. Alternatively, the first data of the first service includes data stored in the access network device or data generated or collected directly in the terminal. Alternatively, the first data of the first service is sourced from the access network device and is destined for the terminal. Alternatively, the first data of the first service includes data stored in the access network device or data generated or collected directly in the access network device.

[0129] In step S2102, the terminal sends a first request to the access network device based on the first service, where the first request is used to request establishment of a channel between the terminal and the access network device.

[0130] In the embodiments of the present disclosure, the terminal learns of the first service, and then determines whether to send the first 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.

[0131] In some embodiments, the embodiments of the present disclosure actually determine whether the terminal establishes the channel between the terminal and the access network device based on the first service, or establishes other channels. For example, the terminal needs to establish a related channel with a core network device through the access 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 (DN) device. Alternatively, the embodiments of the present disclosure can also be understood as the terminal making a decision on the established channel based on the first service, and then requesting 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.

[0132] In some embodiments, the terminal determines whether to request to establish a channel between the terminal and the access network device based on a service type of the first service, and further determines whether to send the first request. Optionally, if the terminal determines that the service type of the first service is a preset type, the terminal sends the first request to request the access network device to establish the channel between the terminal and the access network device. In some embodiments, the first request is used to request to establish the 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 data being transmitted only between the terminal and the access network device, and not being forwarded to the core network device via the access network device. In some embodiments, the channel can also be understood as data being transmitted only 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.

[0133] Optionally, if the terminal determines that the service 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, and there is no need to send the first request. Alternatively, if the terminal determines that the service type of the first service is not the preset type, the terminal establishes another channel between the terminal and the access network device. The other channel herein is, for example, a channel that needs to be established between the terminal and the core network device via the access network device, or a channel that needs to be established between the terminal and a third-party server, such as a data network (DN) device, via the access network device and the core network device.

[0134] 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.

[0135] Optionally, the first request includes a first indication, and the first indication is used to directly indicate to establish the channel between the terminal and the access network device. In the embodiments of the present disclosure, the type of the channel to be established is determined by the terminal, and the access network device is directly informed of the need to establish the channel with the terminal through the first request.

[0136] 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 establishing the channel.

[0137] In some embodiments, the preset type is any of the following:

[0138] (1) an AI type.

[0139] 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.

[0165] In some embodiments, the terminal maps the first data to the radio bearer corresponding to the traffic type of the first data based on the traffic type of the first data. Alternatively, the above-mentioned embodiments can also be understood as that the terminal maps the first data to the corresponding radio bearer by one-step mapping. Optionally, the traffic type of the first data has a corresponding relationship with the radio bearer, and the corresponding radio bearer can be determined based on the traffic type of the first data.

[0166] In some embodiments, the traffic type of the traffic data corresponds to the radio bearer one by one. In some embodiments, the corresponding relationship between the traffic type of the traffic data and the radio bearer does not need to be configured, but is pre-set. For example, the AI traffic is mapped to the first type of radio bearer, and the sensing traffic is mapped to the second type of radio bearer.

[0191] (5) Priority of the QoS rule.

[0192] In some embodiments, the priority of the QoS rule is used to specify the execution order of the QoS rule. Alternatively, the QoS rules are executed in the order of the priority from small to large.

[0193] In some embodiments, the QoS rule can be determined in various ways. Alternatively, the QoS rule is determined in any other way:

[0194] 1. The terminal receives second information, and the second information is used to configure the QoS rule.

[0195] In the embodiments of the present disclosure, the QoS rule of the terminal is configured by information.

[0196] In some embodiments, the second information is sent by the access network device. Optionally, the second information is carried in RRC signaling, or the second information is carried in control signaling between the terminal and the access network device. For example, if the second information is sent by the access network device, the second information can be carried in RRC signaling. Alternatively, it can also be understood that the access network device configures the mapping relationship between the service type and the radio bearer through RRC signaling. For another example, if the second information is sent by the access network device, the second information can be control signaling between the terminal and the access network device. Alternatively, it can also be understood that the access network device configures the mapping relationship between the service type and the radio bearer through the control signaling between the terminal and the access network device. It should be noted that when the access network device adds or modifies the radio bearer, the access network device specifies the service type corresponding to the radio bearer. For example, the access network device configures that the service corresponding to the radio bearer of the first type is AI service, and the service corresponding to the radio bearer of the second type is sensing service.

[0197] In some embodiments, the second information is sent by the core network device. For example, if the second information is sent by the core network device, the second information can be carried in NAS signaling.

[0200] 3. The QoS rule is generated by the terminal based on the downlink data received through reflective QoS.

[0201] In the embodiments of the present disclosure, the QoS rule is generated by the terminal through application of reflective QoS (Reflective QoS), and the QoS rule suitable for uplink is generated according to the received downlink data packet.

[0202] In some embodiments, the mapping relationship between the QoS flow and the radio bearer also needs to be configured in advance. Optionally, the terminal receives third information, and the third information is used to configure the mapping relationship between the QoS flow and the radio bearer. In some embodiments, the third information is sent by the access network device. It can also be understood that the access network device sends the third information to the terminal, and the terminal receives the third information to determine the mapping relationship between the indicated QoS flow and the radio bearer. For example, if the third information is sent by the access network device, the third information can be carried in the RRC signaling. Alternatively, it can also be understood that the access network device configures the mapping relationship between the service type and the radio bearer through the RRC signaling. For another example, if the third information is sent by the access network device, the third information can be the control signaling between the terminal and the access network device. Alternatively, it can also be understood that the access network device configures the mapping relationship between the service type and the radio bearer through the control signaling between the terminal and the access network device. It should be noted that when the access network device adds or modifies the radio bearer, the access network device specifies the service type corresponding to the radio bearer. For example, the access network device configures that the service corresponding to the radio bearer of the first type is an AI service, and the service corresponding to the radio bearer of the second type is a perception service.

[0203] In some embodiments, the terminal receives second data of the first service, maps the first data to a QoS flow corresponding to a QoS identifier of the second data, and then maps the QoS flow corresponding to the QoS identifier to the radio bearer corresponding to the QoS identifier. Alternatively, it can also be understood that the terminal maps the first data to the radio bearer corresponding to the QoS identifier of the second data.

[0204] In some embodiments, the terminal maps the QoS flow corresponding to the first data to the corresponding radio bearer based on the SDAP layer.

[0219] In the embodiments of the present disclosure, the terminal maps the service data to be sent to the radio bearer, and then sends the service data to the access network device.

[0220] It should be noted that the above steps S2104-S2105 are described by taking how the terminal maps the first data of the first service to the radio bearer and then sends it to the access network device as an example. In another embodiment, the access network device can also map the third data of the first service to the corresponding radio bearer and then send it to the terminal. Next, how the access network device maps the third data to the corresponding radio bearer is described.

[0221] In some embodiments, the access network device maps the third data to the radio bearer corresponding to the service type of the third data based on the service type of the third data.

[0222] In some embodiments, the service type of the service data corresponds to the radio bearer in a one-to-one manner.

[0223] In some embodiments, the access network device configures itself, or the core network device sends the first information, where the first information is used to configure a mapping relationship between a service type and a radio bearer.

[0224] The access network device mapping method is similar to the terminal mapping method in the above embodiment, and will not be described in detail here.

[0226] In some embodiments, the access network device maps the third data to a QoS flow corresponding to the QoS rule based on the QoS rule satisfied by the third data. The QoS rule is similar to that in the above embodiment and will not be described in detail here.

[0227] In some embodiments, the access network device receives fourth data of the first service, maps the third data to a QoS flow corresponding to a QoS identifier of a QoS flow of the fourth data, and then maps the QoS flow corresponding to the QoS identifier to a radio bearer corresponding to the QoS identifier. Alternatively, it can be understood that the terminal maps the third data to a radio bearer corresponding to the QoS identifier of the fourth data.

[0228] In some embodiments, the access network device maps the QoS flow corresponding to the third data to the corresponding radio bearer based on the SDAP layer.

[0229] The data mapping method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2105. For example, step S2101 can be implemented as an independent embodiment, step S2102 can be implemented as an independent embodiment, step S2103 can be implemented as an independent embodiment, step S2104 can be implemented as an independent embodiment, steps S2101 and S2102 can be implemented as independent embodiments, steps S2101 and S2103 can be implemented as independent embodiments, steps S2101 and S2104 can be implemented as independent embodiments, steps S2102 and S2103 can be implemented as independent embodiments, steps S2102 and S2104 can be implemented as independent embodiments, and steps S2103 and S2104 can be implemented as independent embodiments, but the present invention is not limited thereto.

[0230] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0231] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0232] In some embodiments, step S2103 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0233] In some embodiments, step S2104 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0234] In some embodiments, step S2105 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0235] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2A .

[0236] FIG2B is an interactive diagram of a protocol determination method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a protocol determination method, which includes:

[0237] Step S2201: The terminal obtains first data of a first service.

[0238] Among them, step S2201 in the embodiment of the present disclosure is similar to step S2101 in the above embodiment and will not be repeated here.

[0239] In step S2202, the terminal sends a second request to the access network device, where the second request is used to request the access network device to establish a channel between the terminal and the access network device for the first service. In one example, the second request includes information about the first service.

[0240] In some embodiments, the access network device receives the second request sent by the terminal. In some embodiments, the terminal sends the second request. Correspondingly, the access network device receives the second request.

[0241] In the embodiment of the present disclosure, the terminal carries the first service in the second request, thereby ensuring that the access network device establishes a channel based on the included first service after receiving the second request.

[0242] Step S2203: The access network device establishes a channel between the terminal and the access network device based on the second request.

[0243] In some embodiments, the access network device establishes the channel between the terminal and the access network device based on the first service included in the second request, including: determining, by the access network device, whether to establish the channel between the terminal and the access network device based on the type of the first service included in the second request.

[0244] In some embodiments, the disclosure actually means that after the terminal sends the second request, the access network device decides whether to establish the channel between the terminal and the access network device based on the first service included in the second request, 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 to establish a related channel through the access network device, the core network device and a third-party server, such as a data network (DN) device. Alternatively, the disclosure can also be understood as that the access network device makes a decision on the established channel based on the first service, and the terminal only plays a role in requesting to establish the channel and does not have the ability to decide which channel to establish.

[0245] In some embodiments, the access network device determines whether to establish the channel between the terminal and the access network device based on the type of the first service. Optionally, if the access network device determines that the type of the first service is a preset type, the channel between the terminal and the access network device is established. In some embodiments, 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 data being transmitted only between the terminal and the access network device, and then being forwarded to the core network device through the access network device. In some embodiments, the channel can also be understood as data being transmitted only 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.

[0246] 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 the type of the first service is determined to be not the preset type, other channels between the terminal and the access network device are established. For example, the terminal needs to establish a related channel through the access network device and the core network device, or to establish a related channel through the access network device, the core network device and a third-party server, such as a data network (DN) device.

[0247] In some embodiments, the access network device establishes the channel between the terminal and the access network device based on the first service included in the second request, including: establishing, by the access network device, a radio bearer between the terminal and the access network device based on the first service included in the second request.

[0248] The access network device determines whether to establish the channel between the terminal and the access network device based on the first service, which is similar to the manner in which the terminal confirms in step S2101 in the above-described embodiments, and thus is not described herein again.

[0249] In step S2204, the terminal maps the first data of the first service to a radio bearer.

[0250] In step S2204, the terminal maps the first data of the first service to a radio bearer.

[0251] In step S2205, the terminal sends the first data of the first service to the access network device based on the radio bearer.

[0252] In step S2205, the terminal sends the first data of the first service to the access network device based on the radio bearer.

[0254] In some embodiments, step S2201 is optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0255] In some embodiments, step S2202 is optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0256] In some embodiments, step S2203 is optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0257] In some embodiments, step S2204 is optional, and one or more of the steps can be omitted or replaced in different embodiments.
