[0103] 2. Access network equipment

[0104] In some embodiments of this disclosure, the access network device is a device that provides wireless communication functions for terminal devices, and may also be referred to as a radio access network (RAN) device or access network element. The access network device may support at least one wireless communication technology, such as LTE, NR, 6G wireless communication technology, etc.

The equipment providing base station functionality in NR includes next-generation node base stations (gNBs) and the continuously evolving node B (ng-eNB). The gNB communicates with terminal devices using NR technology, while the ng-eNB communicates with terminal devices using evolved universal terrestrial radio access (E-UTRA) technology.

In some embodiments of this disclosure, the core network may be, for example, an evolved packet core (EPC), a 5G core network, or a novel core network in future communication systems.

[0110] For example, a 5G core network consists of a set of network elements, such as access and mobility management function (AMF), user plane function (UPF), and session management function (SMF). Among them, AMF can implement functions such as mobility management, UPF can provide functions such as packet routing and forwarding and quality of service (QoS) management, and SMF can provide functions such as session management, IP address allocation and management.

[0111] An EPC can consist of a mobility management entity (MME), a serving gateway (S-GW), and a public data network (PDN) gateway (P-GW). The MME provides functions such as mobility management and gateway selection, the S-GW provides functions such as packet forwarding, and the P-GW provides functions such as terminal address allocation and rate control.

[0112] For multicast broadcast service (MBS), the core network can include several new network elements to implement functions such as packet forwarding, MBS conference management, QoS management, and transmission mode switching (switching between unicast and multicast / broadcast transmission modes).

[0113] Another approach is that the function can be implemented by existing core network elements.

[0114] In some embodiments, core network elements may also be devices, modules, units, processors, module devices, chips, chip systems, etc. A chip system may include chips, and may also include other discrete devices.

The communication link used for downlink communication is the uplink. The data transmitted on the downlink is downlink data. The transmission direction of the downlink data is the downlink direction.

[0123] Data organization: Organizing data or arranging data in a way that allows for processing.

[0124] Data computation: performing various arithmetic and logical operations to obtain further information.

[0125] Data redundancy handling: An attribute is likely redundant if it can be derived from another attribute or another set of attributes. Inconsistent attribute or dimension naming can also lead to redundancy in a dataset. Common methods for redundancy correlation analysis include Pearson product-moment coefficient, chi-square test, and covariance of numerical attributes.

[0126] Numerical reduction: reducing the amount of data by choosing alternative data representations. For example, parametric models (such as linear regression models) can be used instead of actual data, or methods such as clustering, sampling, and histograms can be used to reduce the amount of data.

[0127] Data compression: Data compression algorithms (such as principal component analysis (PCA) and singular value decomposition (SVD)) map data from a high-dimensional space to a low-dimensional space to reduce the storage and computational burden. Data reduction techniques can mitigate problems by reducing dimensionality (called dimensionality reduction) or by reducing the amount of data (called instance selection and sampling).

[0128] Numerical reduction: reducing the amount of data by choosing alternative data representations. For example, parametric models (such as linear regression models) can be used instead of actual data, or methods such as clustering, sampling, and histograms can be used to reduce the amount of data.

[0130] Video rendering includes one or more of the following:

[0131] Compositing: In the final stage of video editing, all elements (including video clips, images, text overlays, computer-generated imagery (CGI) effects, etc.) are combined together to form a unified sequence.

[0132] Color correction: Adjusting the colors of a video to ensure color consistency and optimize visual effects.

[0133] Effects application: Applying various visual effects, such as transitions, filters, motion graphics, and 3D animation.

[0134] Audio mixing: Combining different audio tracks (dialogue, music, sound effects) together, balancing and adjusting them to create the final audio experience.

[0135] Encoding: Converting video into a specific format and codec to suit different playback environments and network transmissions.

For example, the first information may directly indicate the first wireless parameter by including it. Alternatively, the first information may indirectly indicate the first wireless parameter by including an index or identifier corresponding to it.

[0152] Optionally, the first wireless parameters include the mapping relationship between the first data stream and the first DRB, and / or the configuration parameters of the first DRB. This allows the terminal device to determine the first DRB and then use the first DRB to send data packets corresponding to the first QoS parameter group, which helps to meet QoS requirements. The mapping relationship between the first data stream and the first DRB can also be referred to as: the mapping relationship from the first data stream to the first DRB, or the mapping relationship from the first data stream to the first DRB.

[0153] Alternatively, the configuration parameters of the first DRB may include the parameter configuration of the protocol layer corresponding to the first DRB, such as one or more of the following: packet data convergence protocol (PDCP) layer parameters, radio link control (RLC) layer parameters, and configuration parameters of the logical channel corresponding to the first DRB. The configuration parameters of the logical channel may include, for example, logical channel priority and / or priori bit rate (PBR).

[0154] Optionally, the first wireless parameters may also include the protocol layer parameter configurations corresponding to the data packets of the first data stream or the first QoS parameter group. For example, the PDCP layer parameters may be configured according to the first data stream or the first QoS parameter group, and different RLC entities may be configured according to different importance.

[0155] In one optional implementation, the first information includes an identifier for a first QoS parameter group. Thus, based on the identifier of the first QoS parameter group in the first information, the terminal device can determine that the first radio parameters indicated by the first information correspond to the first QoS parameter group, and thereby can send data packets in the first data stream corresponding to the first QoS parameter group based on the first radio parameters.

[0156] In an optional implementation, the first information is further used to indicate a first resource, which is used to transmit data packets corresponding to the first QoS parameter group in the first data stream. Then, in step S302, the terminal device can send data packets corresponding to the first QoS parameter group in the first data stream on the first resource based on the first radio parameters.

[0157] 2. Second Information

[0158] In one alternative implementation, the second information may directly or indirectly indicate the second wireless parameter. For example, the second information may directly indicate the second wireless parameter by including it. Alternatively, the second information may indirectly indicate the second wireless parameter by including an index or identifier corresponding to it.

[0159] Optionally, the second wireless parameters include the mapping relationship between the first data stream and the second DRB, and / or the configuration parameters of the second DRB. The mapping relationship between the first data stream and the second DRB can also be referred to as: the mapping relationship from the first data stream to the second DRB, or the mapping relationship from the first data stream to the second DRB. This allows the terminal device to determine the second DRB and then use the second DRB to send data packets corresponding to the second QoS parameter group, which is beneficial for meeting QoS requirements.

[0160] Alternatively, the configuration parameters of the second DRB may include the parameter configuration of the protocol layer corresponding to the second DRB, such as one or more of the following: PDCP layer parameters, RLC layer parameters, and configuration parameters of the logical channel corresponding to the first DRB. The configuration parameters of the logical channel may include, for example, logical channel priority and / or PBR.

[0161] Optionally, the second wireless parameters may also include the protocol layer parameter configurations corresponding to the data packets of the second data stream or the second QoS parameter group. For example, in the PDCP layer parameters, packet loss timer parameters may be configured according to the second data stream or the second QoS parameter group, and different RLC entities may be configured according to different importance.

[0162] In one optional implementation, the second information includes an identifier for a second QoS parameter group. Thus, based on the identifier of the second QoS parameter group in the second information, the terminal device can determine that the second radio parameters indicated by the second information correspond to the second QoS parameter group, and thereby can send data packets in the first data stream corresponding to the second QoS parameter group based on the second radio parameters.

[0163] In one optional implementation, the second information is further used to indicate a second resource, which is used to transmit data packets corresponding to the second QoS parameter group in the first data stream. Then, in step S304, the terminal device can send data packets corresponding to the second QoS parameter group in the first data stream on the second resource based on the second radio parameters.

[0164] In one optional implementation, the first information and the second information are transmitted sequentially. Alternatively, the first information and the second information are transmitted simultaneously. These two methods are described below as examples, as described in optional implementation 1 and implementation 2.

[0165] In implementation method 1, the first information and the second information are transmitted sequentially.

[0166] For example, for an access network device, the access network device first sends the first information and then sends the second information. Correspondingly, for a terminal device, the terminal device first receives the first information and then receives the second information.

[0167] Based on the scheme where the first information and the second information are received sequentially, optionally, the first information may be used to indicate the first radio parameters initially configured for the terminal device based on the first QoS parameter group, and the second information may be used to indicate the second radio parameters reconfigured for the terminal device based on the second QoS parameter group. This is so that when the QoS parameter group is updated from the first QoS parameter group to the second QoS parameter group, the second radio parameters can better adapt to the updated QoS parameter group. Consequently, the terminal device uses the second radio parameters to transmit data packets corresponding to the updated QoS parameter group, which is beneficial for meeting QoS requirements.

[0168] Optionally, the access network device first sends a first message, which can be understood as: the access network device uses the first message to initially configure radio parameters for the first data stream, and the initially configured radio parameters are the first radio parameters. The access network device then sends a second message, which can be understood as: the access network device uses the second message to reconfigure the radio parameters for the first data stream, and the reconfigured radio parameters are the second radio parameters. The second message can, for example, be a radio resource control (RRC) reconfiguration message.

[0169] For example, the access network device initially configures first radio parameters for the first data stream using first information, including the mapping relationship between the first data stream and the first DRB. The terminal device sends data packets corresponding to the first QoS parameter group in the first data stream on the first DRB. The access network device reconfigures second radio parameters for the first data stream using the first information, including the mapping relationship between the first data stream and the second DRB. Therefore, the access network device reconfigures the mapping of the first data stream from the first DRB to the second DRB. The terminal device then sends data packets corresponding to the second QoS parameter group in the first data stream on the second DRB.

[0170] The specific method for initially configuring the wireless parameters of the access network device can be any one of the following optional methods A to C.

[0171] Method A: When the access network device performs initial radio parameter configuration for the first data stream, the terminal device is configured with first radio parameters based on the default QoS parameter group corresponding to the first data stream. It is evident that the first radio parameters are the radio parameters configured for the first data stream based on the default QoS parameter group corresponding to the first data stream; therefore, the first QoS parameter group is the default QoS parameter group for the first data stream. In some embodiments of this disclosure, the default QoS parameter group corresponding to the data stream is the QoS parameter group determined by the terminal device when no data processing is performed on the data stream.

[0172] Method B: When the access network device performs initial radio parameter configuration for the first data stream, the terminal device is configured with the first radio parameters according to a QoS parameter group indicated by the core network device. Understandably, the core network device sends information indicating the first QoS parameter group to the access network device, and the access network device determines the first information based on this information. Optionally, the information indicating the first QoS parameter group includes one or more of the following: QoS parameters in the first QoS parameter group, the index value of the first QoS parameter group, or an identifier of the first QoS parameter group.

[0173] Optionally, the core network device sends fourth information to the access network device. This fourth information indicates one or more QoS parameter groups corresponding to the first data stream, and indicates that the currently used QoS parameter group is the first QoS parameter group. In this way, the access network device can determine one or more QoS parameter groups corresponding to the first data stream based on the fourth information, and determine that the first QoS parameter group is currently used to initially configure the radio parameters for the first data stream.

[0174] The fourth piece of information can indicate one or more QoS parameter groups corresponding to the first data stream, either directly or indirectly.

[0175] For example, the fourth information directly indicates one or more QoS parameter groups corresponding to the first data stream by including the QoS parameters in each of the one or more QoS parameter groups corresponding to the first data stream. Further optionally, the fourth information may include the QoS parameters in the QoS parameter groups and the index value or identifier corresponding to the QoS parameter groups.

[0176] For example, the fourth information indirectly indicates one or more QoS parameter groups corresponding to the first data stream by including the index value or identifier of each QoS parameter group in one or more QoS parameter groups corresponding to the first data stream. For example, the QoS parameter groups corresponding to the first data stream include QoS parameter group #1, QoS parameter group #2, and QoS parameter group #3, where the index value of QoS parameter group #1 is 001, the index value of QoS parameter group #2 is 002, and the index value of QoS parameter group #3 is 003; the fourth information includes: 001, 002, and 003.

[0177] Optionally, the index value or identifier of the QoS parameter group is specified by the protocol. For example, the protocol specifies that QoS parameter group #1 represents priority level = 2, packet delay budget = 20ms, and packet loss rate = 5%.

[0178] Furthermore, the fourth information can indicate, directly or indirectly, that the currently used QoS parameter group is the first QoS parameter group. For example, the fourth information may include information indicating the first QoS parameter group. For details regarding the information indicating the first QoS parameter group, please refer to the foregoing explanations; they will not be repeated here.

[0179] Method C: When the access network device performs initial radio parameter configuration for the first data stream, the first radio parameters are configured for the terminal device according to a QoS parameter group indicated by the terminal device. Understandably, the terminal device sends information indicating the first QoS parameter group to the access network device, and the access network device determines the first information based on the information indicating the first QoS parameter group. Optionally, the information indicating the first QoS parameter group includes one or more of the following: QoS parameters in the first QoS parameter group, the index value of the first QoS parameter group, or an identifier of the first QoS parameter group.

[0180] Optionally, before sending information indicating the first QoS parameter group to the access network device, the terminal device further determines the first QoS parameter group.

[0181] Optionally, the method further includes: the QoS policy configuration device sending third information, the third information indicating one or more QoS rules and QoS parameter groups corresponding to the one or more QoS rules; correspondingly, the terminal device receiving the third information. The terminal device determining the first QoS parameter group includes: the terminal device determining the first QoS parameter group based on the third information and the first data stream. Here, one or more QoS rules and the QoS parameter groups corresponding to the one or more QoS rules can also be collectively referred to as QoS policies. Therefore, the QoS policy configuration device sends the QoS policies to the terminal device through the third information. Furthermore, the relationship between QoS rules and QoS parameter groups can be, for example, one-to-one, meaning that each QoS rule can correspond to one QoS parameter group.

[0182] Based on the above scheme, it is beneficial to configure different QoS parameter groups for data streams of different data types and / or for different processing methods / steps of data streams by terminal devices. This improves the granularity of QoS and enables dynamic and flexible QoS control for terminal devices with different data processing capabilities. Terminal devices can select appropriate QoS parameter groups based on the actual data stream data type / processing method / step, which helps to meet QoS requirements.

[0183] Optionally, the third information can indicate one or more QoS parameter groups corresponding to QoS rules, either directly or indirectly.

[0184] For example, the third information can directly indicate the QoS parameter group corresponding to one or more QoS rules by including the QoS parameter group corresponding to one or more QoS rules. Optionally, in addition to including the QoS parameter group corresponding to one or more QoS rules, the third information can also indicate the index value or identifier of the QoS parameter group.

[0185] For example, the third information indirectly indicates the QoS parameter group corresponding to one or more QoS rules by including the index value or identifier of the QoS parameter group corresponding to one or more QoS rules.

[0186] QoS rules are used to indicate one or more of the following: data type, data processing method, and data processing steps. For example, a QoS rule can refer to a set of characteristics, based on which a data stream and corresponding QoS parameter set can be matched. These characteristics may include one or more of the following: data type, data processing method, and data processing steps.

[0187] Optionally, the data type is one of the following: raw data, compressed data, data after grouping, data after redundancy processing, encoded data, calculated data, or rendered data.

[0188] Optionally, data processing methods may include one or more of the following: data compression, data grouping, data redundancy handling, data encoding, data computation, and data rendering. For example, data rendering may include one or more of the following: compositing, audio mixing, encoding, resolution and frame rate settings, and bitrate control. For example, if the data is video data, data rendering may be video rendering; for an explanation of video rendering, please refer to the aforementioned related concepts, which will not be repeated here.

[0189] Optionally, data processing steps are used to indicate the order or sequence of data processing methods within the data processing flow. For example, multiple data processing methods in the data processing flow, arranged in the order of execution, might be: data compression, data grouping, data redundancy processing, and data encoding. Thus, data compression is step 1 in the data processing flow, data grouping is step 2, data redundancy processing is step 3, and data encoding is step 4.

[0190] Optionally, the QoS rule also includes the identifier of the data flow corresponding to the QoS rule. In some embodiments of this disclosure, the data flow can be a data flow or a QoS flow, and the name is not limited in some embodiments of this disclosure. The identifier of the data flow can be a data flow ID or a QoS flow ID. Optionally, the first information may also include a protocol data unit (PDU) set ID.

[0191] Optionally, the first QoS parameter group determined by the terminal device is the QoS parameter group corresponding to the QoS rule that matches the first data stream in one or more QoS rules.

[0192] Example 1: QoS rules are used to indicate data types. The terminal device determines the QoS rule that matches the data type of the first data stream from one or more QoS rules, and then determines the QoS parameter group corresponding to the matching QoS rule as the first QoS parameter group. The data type can be identified and determined, for example, through the packet header format.

[0193] For example, QoS rule #1 indicates the data type as raw data, QoS rule #2 indicates the data type as compressed data, and QoS rule #3 indicates the data type as data after packet processing. The first data stream is compressed data. Therefore, the data type indicated by QoS rule #2 matches the data type of the first data stream, and the terminal device determines the QoS parameter group corresponding to QoS rule #2 as the first QoS parameter group.

[0194] Example 2: QoS rules are used to indicate the data processing method. The terminal device determines the QoS rule that matches the data processing method of the terminal device for the first data stream from one or more QoS rules, and then determines the QoS parameter group corresponding to the matching QoS rule as the first QoS parameter group.

[0195] For example, QoS rule #1 indicates data compression, QoS rule #2 indicates data packetization, and QoS rule #3 indicates data redundancy processing. The terminal device processes the first data stream using data compression. Therefore, the data processing method indicated by QoS rule #2 matches the terminal device's data processing method for the first data stream, and the terminal device determines the QoS parameter group corresponding to QoS rule #2 as the first QoS parameter group.

[0196] Example 3: QoS rules are used to indicate data processing steps. The terminal device determines from one or more QoS rules the QoS rule that matches the data processing steps of the terminal device for the first data stream, and then determines the QoS parameter group corresponding to the matching QoS rule as the first QoS parameter group.

[0197] For example, the multiple data processing methods in the data processing flow, arranged in the order of execution, are: data compression, data grouping, data redundancy processing, and data encoding. QoS rule #1 indicates the first step in the data processing flow, QoS rule #2 indicates the second step, QoS rule #3 indicates the third step, and QoS rule #4 indicates the fourth step. The terminal device's data processing method for the first data stream is data compression; therefore, the terminal device's data processing step for the first data stream is the second step in the data processing flow. Thus, the data processing step indicated by QoS rule #2 matches the terminal device's data processing step for the first data stream, and the terminal device determines the QoS parameter group corresponding to QoS rule #2 as the first QoS parameter group.

[0198] Alternatively, the terminal device can determine the identifier of the first data stream based on the third information and the first data stream. This method can be applied, for example, to a scenario where QoS rules include the identifier of the data stream corresponding to the QoS rules. For instance, the terminal device determines from one or more QoS rules the QoS rule that matches the data stream from the upper layer (such as the application layer) or the data stream from the previous network element, thereby determining the identifier of the data stream corresponding to the QoS rule, which is the identifier of the first data stream.

[0199] The above provides an exemplary description of the specific methods for initial configuration of wireless parameters of access network devices. The following provides an exemplary description of the specific methods for reconfiguring wireless parameters of access network devices. The specific methods for reconfiguring wireless parameters of access network devices can be any one of the following optional methods 1 to 3.

[0200] Method 1: The terminal device sends information indicating the second QoS parameter group to the access network device, and correspondingly, the access network device receives the information indicating the second QoS parameter group from the terminal device. The access network device determines the second information based on the information indicating the second QoS parameter group.

[0201] Understandably, when the access network device reconfigures radio parameters for the first data stream, it reconfigures the radio parameters according to a QoS parameter set indicated by the terminal device. The reconfigured radio parameters are the second radio parameters. For example, after receiving the initially configured radio parameters from the access network device, the terminal device may determine a QoS parameter set different from the first QoS parameter set, i.e., the second QoS parameter set. The terminal device reports the second QoS parameter set to the access network device so that the access network device can reconfigure the radio parameters based on the second QoS parameter set using the second information.

[0202] In one possible scenario, the terminal device determines a QoS parameter group that is different from the first QoS parameter group because the terminal device's data processing method for the first data stream has changed. The terminal device determines a QoS rule from one or more QoS rules that matches the changed data processing method, and thus determines the QoS parameter group corresponding to the QoS rule as the second QoS parameter group.

[0203] For example, the terminal device initially uses data processing method #1 for the first data stream. The terminal device determines the QoS parameter group #1 that matches the QoS rule and feeds back QoS parameter group #1 to the access network device. The access network device initially configures the radio parameters based on QoS parameter group #1 and sends it to the terminal device. Then, the terminal device updates the data processing method for the first data stream to data processing method #2. The terminal device determines the QoS parameter group #2 that matches the QoS rule and feeds back QoS parameter group #2 to the access network device. The access network device reconfigures the radio parameters based on QoS parameter group #2 and sends it to the terminal device.

[0204] Furthermore, the terminal device determines a second QoS parameter group corresponding to the QoS rule that matches the changed data processing method from one or more QoS rules. This is similar to the terminal device determining a first QoS parameter group corresponding to the QoS rule that matches the original data processing method from one or more QoS rules; the foregoing explanation of the terminal device determining the first QoS parameter group is relevant. Optionally, the one or more QoS rules and the corresponding QoS parameter groups can be determined by the terminal device using third information, as detailed in the foregoing explanation. Further elaboration is omitted here.

[0205] Optionally, the information used to indicate the second QoS parameter group includes one or more of the following: QoS parameters in the second QoS parameter group, index value of the second QoS parameter group, and QoS parameters in the second QoS parameter group that have changed incrementally compared to the first QoS parameter group.

[0206] For example, the terminal device determines the index value of one or more QoS parameter groups based on the received third information, and then sends the index value of the second QoS parameter group to the access network device. The third information indicates one or more QoS rules and the index value of the QoS parameter group corresponding to those rules. For details on the third information, please refer to the foregoing explanation; it will not be repeated here.

[0207] For example, the terminal device can report incrementally changed QoS parameters, that is, QoS parameters that have changed compared to the first QoS parameter group. For instance, if the latency value in the second QoS parameter group differs from the latency value in the first QoS parameter group, the terminal device will include the latency value from the second QoS parameter group in the information it sends to indicate the second QoS parameter group. Or, if the first QoS parameter group does not include a rate value, but the second QoS parameter group does, the terminal device will include the rate value from the second QoS parameter group in the information it sends to indicate the second QoS parameter group.

[0208] In addition, some embodiments of this disclosure do not limit the signaling used to carry information indicating QoS parameter groups (e.g., a first QoS parameter group, a second QoS parameter group). For example, the terminal device can carry information indicating the second QoS parameter group through RRC signaling, media access control control element (MAC CE), or uplink control information (UCI).

[0209] Method 2: The core network device sends information indicating the second QoS parameter group to the access network device, and correspondingly, the access network device receives the information indicating the second QoS parameter group from the core network device. The access network device determines the second information based on the information indicating the second QoS parameter group.

[0210] Understandably, when the access network device reconfigures the radio parameters for the first data stream, it reconfigures the radio parameters according to a QoS parameter group indicated by the core network device, and the reconfigured radio parameters are the second radio parameters.

[0211] Method 3: The terminal device sends computing power information to the access network device; correspondingly, the access network device receives the computing power information from the terminal device. The access network device determines the second information based on this computing power information. Based on the above scheme, it is beneficial for the access network device to determine the second QoS parameter group based on the computing power information of the terminal device, and then determine the second information based on the determined second QoS parameter group.

[0212] Optionally, the computing power information is used to indicate one or more of the following: computing power value, data processing method, and data processing steps. The data processing method can be understood as the data processing method performed or to be performed by the terminal device on the first data stream, and the data processing steps can be understood as the data processing steps performed or to be performed by the terminal device on the first data stream. For further details on the data processing method and data processing steps, please refer to the foregoing explanations; they will not be repeated here.

[0213] Optionally, the access network device determines the second information based on the computing power information, including: the access network device determines a second QoS parameter group based on the computing power information; the access network device determines the second information based on the second QoS parameter group.

[0214] In implementation method 2, the first information and the second information are transmitted simultaneously.

[0215] For example, for an access network device, the access network device simultaneously sends the first information and the second information. Correspondingly, for a terminal device, the terminal device simultaneously receives the first information and the second information.

[0216] In the scheme where the first and second information are received simultaneously, the terminal device can be configured with multiple wireless parameters at the same time. The terminal device can choose to use the wireless parameters corresponding to the QoS parameter group based on the data stream to send the data packets corresponding to the QoS parameter group, which is beneficial to meeting QoS requirements.

[0217] Optionally, the access network device sends fifth information, which indicates multiple radio parameters configured for the first data stream. These multiple radio parameters include first radio parameters and second radio parameters. Therefore, the fifth information includes both first and second information. The fifth information can be carried, for example, in an RRC configuration message or an RRC reconfiguration message. Additionally, optionally, any of the multiple radio parameters can include the mapping relationship between the first data stream and the DRB and / or the DRB configuration parameters. Similar to the aforementioned first and second radio parameters, please refer to the relevant descriptions above; further details will not be repeated here.

[0218] Optionally, the first data stream corresponds to multiple QoS parameter groups, and any one of the multiple wireless parameters corresponds to one or more QoS parameter groups.

[0219] Optionally, the fifth information may also indicate the correspondence between each of the multiple radio parameters and the QoS parameter group. For example, taking the first radio parameter and the second radio parameter as examples, the first information in the fifth information indicates the first radio parameter and the correspondence between the first radio parameter and the first QoS parameter group, and the second information in the fifth information indicates the second radio parameter and the correspondence between the second radio parameter and the second QoS parameter group.

[0220] In one alternative approach, the method further includes: the access network device receiving sixth information from a terminal device or a core network device, the sixth information being used to indicate multiple QoS parameter groups corresponding to the first data stream. For example, the sixth information can directly indicate the multiple QoS parameter groups corresponding to the first data stream by including the multiple QoS parameter groups. Alternatively, the sixth information can indirectly indicate the multiple QoS parameter groups corresponding to the first data stream by including index values ​​or identifiers of the multiple QoS parameter groups. No limitation is imposed in this regard.

[0221] In another optional approach, the method further includes: the terminal device sending its capability information to the access network device; and correspondingly, the access network device receiving the terminal device's capability information. Based on the terminal device's capability information and QoS rules, the access network device determines multiple QoS parameter groups corresponding to the first data stream.

[0222] Optionally, the terminal device's capability information indicates one or more of the following: the terminal device's computing power, data processing method, and data processing steps. The data processing method can be understood as the data processing method performed or to be performed by the terminal device on the first data stream, and the data processing steps can be understood as the data processing steps performed or to be performed by the terminal device on the first data stream. For further details on the data processing method and data processing steps, please refer to the foregoing explanations; they will not be repeated here. Additionally, for information on QoS rules, please refer to the foregoing explanations; they will not be repeated here.

[0223] Optionally, the terminal device uses the radio parameters corresponding to the QoS parameter group to send data packets in the first data stream corresponding to that QoS parameter group. For example, after receiving the fifth information, in step S302, the terminal device uses the first radio parameters corresponding to the first QoS parameter group to send data packets in the first data stream corresponding to the first QoS parameter group. In step S304, the terminal device uses the second radio parameters corresponding to the second QoS parameter group to send data packets in the first data stream corresponding to the second QoS parameter group.

[0224] Understandably, in response to the terminal device determining a change in the QoS parameter group, the terminal device uses the radio parameters corresponding to the changed QoS parameter group to send data packets in the first data stream corresponding to the changed QoS parameter group. For example, the terminal device receives the fifth information. The terminal device determines the first QoS parameter group and sends data packets in the first data stream corresponding to the first QoS parameter group based on the first radio parameters. After a period of time, the QoS parameter group changes from the first QoS parameter group to the second QoS parameter group, and the terminal device sends data packets in the first data stream corresponding to the second QoS parameter group based on the second radio parameters. Subsequently, based on a change in the QoS parameter group from the second QoS parameter group to other QoS parameter groups, the terminal device sends data packets in the first data stream corresponding to those other QoS parameter groups based on the radio parameters corresponding to those other QoS parameter groups.

[0225] In one optional implementation, the header of the data packet received by the access network device from the terminal device includes indication information of the QoS parameter group corresponding to the data packet. For example, in step S302, the header of the data packet corresponding to the first QoS parameter group received by the access network device includes indication information of the first QoS parameter group. As another example, in step S304, the header of the data packet corresponding to the second QoS parameter group received by the access network device includes indication information of the second QoS parameter group.

[0226] The indication information of the QoS parameter group may be, for example, the index value of the QoS parameter group, or other identifiers that can indicate the QoS parameter group. Some embodiments of this disclosure do not limit this.

[0227] In addition, the indication information of the QoS parameter group corresponding to the data packet may be carried in the Service Data Adaptation Protocol (SDAP) layer header or the PDCP layer header of the data packet, and some embodiments of this disclosure do not limit this.

[0228] Based on the above scheme, the access network device that receives the data packet can determine the QoS parameter group corresponding to the data packet, so that the access network device can perform next-hop data transmission for the data packet based on the QoS parameter group corresponding to the data packet, which helps to meet QoS requirements.

[0229] In one optional implementation, after the access network device receives the data packet, the method further includes: the access network device performing next-hop data transmission for the data packet based on the QoS parameter group corresponding to the data packet. Understandably, after receiving the data packet, the access network device determines the QoS parameter group corresponding to the data packet and performs next-hop data transmission for the data packet based on the QoS parameter group. For example, the target network element of the next hop can be a core network user plane network element or an external network element.

[0230] For example, after the access network device receives a data packet corresponding to the first QoS parameter group in the first data stream, it performs next-hop data transmission for the data packet based on the first QoS parameter group.

[0231] For example, after the access network device receives the data packet corresponding to the second QoS parameter group in the first data stream, it performs the next-hop data transmission for the data packet based on the second QoS parameter group.

[0232] Optionally, the access network device performs next-hop data transmission for the data packet based on the QoS parameter group corresponding to the data packet, including: setting transmission parameters and / or formulating transmission policies and / or determining routes for the data packet based on the QoS parameter group corresponding to the data packet. It is understood that in response to the access network device sending the data packet to the next network element, processing such as setting, scheduling, or routing based on the QoS parameter group corresponding to the data packet is performed; the implementation method is not limited herein.

[0233] Optionally, the access network device may configure or schedule transmission based on the QoS parameter group corresponding to the data packet, including, for example, resource allocation and rate control for data transmission, priority setting, etc. Optionally, the access network device may configure routing based on the QoS parameter group corresponding to the data packet, including, for example, determining the address of the next hop for the data packet.

[0234] In summary, in this method, the terminal device is configured with first and second wireless parameters, which are wireless parameters configured for the first data stream based on different QoS parameter groups. It is evident that this method configures multiple sets of wireless parameters for the terminal device's first data stream based on different QoS parameter groups. Thus, for data packets in the first data stream corresponding to different QoS parameter groups, the terminal device can use the wireless parameters corresponding to the QoS parameter groups for data packet transmission, which helps ensure that data packets corresponding to different QoS parameter groups can meet their respective QoS requirements.

[0235] This communication method can be applied to scenarios where changes in the way a terminal device processes a data stream cause changes in the QoS parameter group sent for that data stream, thus meeting the QoS requirements in this scenario. For example, when the terminal device processes the data stream in mode #1, the QoS parameter group corresponding to the first data stream is the first QoS parameter group. The terminal device sends data packets from the first data stream corresponding to the first QoS parameter group based on the first radio parameters. When the terminal device changes its data stream processing method from mode #1 to mode #2, the QoS parameter group corresponding to the first data stream changes from the first QoS parameter group to the second QoS parameter group. The terminal device sends data packets from the first data stream corresponding to the second QoS parameter group based on the second radio parameters, ensuring that the data packet transmission after the change in the terminal device's data stream processing method meets the corresponding QoS requirements.

[0267] In summary, in this communication method, the access network device configures multiple sets of radio parameters for the terminal, allowing the terminal device to obtain the corresponding radio parameters based on the actual QoS parameter set used and to transmit data based on these parameters. This communication method is advantageous in situations where the terminal device's data stream processing method changes, enabling flexible and rapid changes to the QoS parameter set and the corresponding data transmission.

[0268] Please refer to Figure 6, which is a schematic diagram of another communication method provided by some embodiments of this disclosure. The communication method includes the following steps:

[0272] Optionally, the QoS rules also include the identifier of the data stream. Based on the third information and the first data stream, the terminal device can determine not only the QoS parameter set matching the first data stream, but also the identifier of the first data stream.

[0273] Optionally, QoS rules are used to indicate data types. The terminal device can determine the QoS rule that matches the data type of the first data stream from one or more QoS rules, and then determine the QoS parameter group corresponding to the QoS rule as the QoS parameter group corresponding to the first data stream.

The terminal device can select a matching QoS parameter group based on the data stream type or the data processing method / steps for the data stream. Compared to using the same QoS parameter settings for different data streams, the methods provided in some embodiments of this disclosure are advantageous in meeting different QoS requirements after flexible data processing.
