[0047] For the convenience of understanding, some contents related to the embodiments of the present application are described as follows:

[0048] I. DC.

[0049] DC provides the terminal with the resources of two network nodes, one of which is called the master node (MN) and the other is called the secondary node (SN). In each network node, the carrier aggregation (CA) technology can also be used, i.e. a series of serving cells controlled by the node are configured for the terminal, which form a cell group. The cell group controlled by the master node MN is the master cell group (MCG), and the cell group controlled by the secondary node SN is the secondary cell group (SCG). Each cell group contains a special cell (SpCell) and a series of secondary cells (SCell). The special cell in the MCG is called the primary cell (PCell), and the special cell in the SCG is called the primary secondary cell (PSCell). DC includes EN-DC, NR-DC, and NE-DC. Among them, E represents the evolved UMTS terrestrial radio access (E-UTRA), and N represents NR.

[0050] II. DualSteer technology.

[0051] DualSteer technology is a method of data offloading at a higher layer than RAN. The essence of DualSteer is also to establish two transmission channels for terminal services at the same time, and operations such as path switching, offloading, and duplicate transmission can be performed between the two transmission channels. DualSteer technology can be divided into DualSteer schemes based on high-layer protocols, such as MP-TCP or MP-QUIC protocols, and DualSteer schemes based on low-layer protocols, such as DualSteer Lower Layer protocol layers introduced below the IP layer.

[0052] III. Access traffic steering, switching, splitting (ATSSS) technology.

[0053] ATSSS is a method of supporting conversion and offloading between 3GPP access and non-3GPP access. Different offloading modes can be configured in ATSSS:

[0054] Active-Standby: Prioritize active path, if it is unavailable, switch to standby path;

[0055] Smallest Delay: Choose path with shortest Round Trip Time (RTT), only for Non-Guaranteed Bit Rate (Non-GBR) traffic;

[0056] Load-Balancing: According to configuration, or based on terminal self-implementation, only for Non-GBR traffic;

[0057] Priority-based: High priority first, if congestion, can split, only for Non-GBR traffic; that is, high priority path is selected first, only when high priority path is congested, part or all data can be split to low priority path;

[0058] Redundant: Configure primary access, which data packets are duplicated and transmitted completely based on implementation.

[0059] A new Performance Measurements Function (PMF) entity is introduced between the terminal and the UPF, which is mainly used for performance detection and measurement, and can be used to measure the end-to-end RTT or packet loss rate (PLR, Packet Loss Rate). The detection result is used to make threshold judgment in various splitting modes, such as the shortest RTT principle, and to judge the congestion principle, and as a reference for various splitting implementations.

[0060] In DC, the terminal has little autonomy, and the flexibility of the split control is poor. In order to ensure the occupancy rate of the new network, the access network equipment may transmit the terminal in the new network with poor control coverage and quality. Therefore, the prior art has poor flexibility of data split control, which not only destroys the user data experience, but also causes additional battery consumption of the user.

[0061] The technologies such as DualSteer and ATSSS of the core network are a way of selecting a path by a terminal and a core network node, and give the UE certain autonomy to make a path selection decision, which is a user-friendly way to some extent. However, since the terminal and the core network node can only make decisions based on some long-period non-real-time end-to-end measurement results when selecting a path. It is unable to make more accurate decisions according to real-time conditions such as link quality conditions, interference conditions, air interface load conditions, and air interface measurement results, etc. Thus, there is a lag and deviation in the selection of the UE data path, which causes the experience and system efficiency to decline. Therefore, there is a large room for improvement.

[0062] To this end, the data splitting processing method of the present application is proposed. The data splitting processing method provided by the embodiments of the present application will be described in detail below in combination with the drawings and some embodiments and their application scenarios.

[0063] Reference Figure 2 The embodiments of the present application provide a data splitting processing method, as shown in Figure 2 The data splitting processing method includes:

[0064] Step 201, the terminal sends a first message to the access network device, the first message is used to request first splitting assistance information, the first splitting assistance information is used to assist the terminal to perform uplink splitting control on at least two transmission paths, the at least two transmission paths are transmission paths in a core network multi-flow connection established between the terminal and the core network device.

[0065] Optionally, the terminal can send the above-mentioned first message by requesting or reporting. Sending the first message to the access network device can be understood as sending the first message to the corresponding serving cell of the access network device.

[0066] Optionally, the above-mentioned at least two transmission paths can be understood as two or more transmission paths established between the terminal and the core network device for services. For example, in some typical scenarios, one path of the two established transmission paths is transmitted through 4G, and the other path is transmitted through 5G; or in future scenarios, one path is transmitted through 5G, and the other path is transmitted through 6G; or one path is transmitted through operator A network, and the other path is transmitted through operator B network; or one path is transmitted through Non Terrestrial Network (NTN) network, and the other path is transmitted through TN network, or one path is transmitted through 3GPP 4G, 5G or 6G base station, and the other path is transmitted through non-3GPP technology such as wifi, etc.

[0067] Optionally, the uplink split control can be understood as that the terminal performs routing selection of uplink data, i.e., selects one path from the at least two transmission paths to perform uplink data transmission.

[0068] It should be understood that the access network device can be understood as a base station or a serving base station of the terminal.

[0069] In the embodiments of the present application, since the terminal requests the first split assistance information from the access network device through the first message, the terminal can perform uplink split control based on the first split assistance information after obtaining the first split assistance information. In this way, the terminal can autonomously implement uplink split control, thereby improving the data split transmission performance.

[0070] Optionally, in some embodiments, before the terminal sends the first message to the access network device, the method further includes:

[0071] The terminal receives a second message sent by the access network device, and the second message is used to indicate that the terminal is supported to send the first message.

[0072] In the embodiments of the present application, supporting the terminal to send the first message can be understood as supporting a new uplink message, i.e., supporting a new request or a new report.

[0073] Optionally, since the process of the terminal sending the first message belongs to a new mechanism, the version and capability of the serving access network device are required, and therefore, before the terminal sends the first message, the permission and support of the access network device need to be obtained. The terminal can only send the first message after obtaining the permission and support of the access network device, which can ensure the validity of the first message transmission and avoid the terminal sending invalid first messages due to the access network device not supporting the terminal to send the first message, thereby causing resource waste.

[0074] Optionally, in some embodiments, the second message is carried through common signaling or dedicated signaling.

[0075] In an embodiment of the present application, the network side device can notify the terminal through public signaling and dedicated signaling. Among them, the public signaling method, for example, carries a 1-bit flag in the system information block (SIB) message, indicating that the serving cell supports the terminal to send the first message. The public signaling method is generally effective for all terminals, unless the public signaling also carries the effective range, or the effective range is agreed upon, for example, the first message can be sent only for dual-stream services under different radio access technology (RAT) base stations of the same operator, or the first message can be sent only for 4G and 5G dual-stream services, 5G and 6G dual-stream services, or the service that allows the first message to be sent has specific characteristics, such as the service quality of service (QoS) meets certain requirements, etc.

[0076] Another dedicated signaling method means that after the terminal enters the connected state, the serving cell can initiate an exclusive license to the terminal based on its current situation or terminal status. For example, the serving cell capability supports the sending of the first message, the current cell system load is not high, or the terminal's business meets certain characteristics, then the terminal will be given an exclusive license.

[0077] It should be understood that no matter which method is used, the terminal can only send the subsequent first message after obtaining permission, so as to avoid the terminal blindly initiating uplink and wasting signaling overhead when the serving cell cannot support it.

[0078] Optionally, in some embodiments, the terminal sending the first message to the access network device includes:

[0079] When the terminal establishes a core network multi-flow connection with the core network device, the terminal sends a first message to the access network device.

[0080] Optionally, in some embodiments, when the terminal establishes a core network multi-flow connection with the core network device, the terminal sending the first message to the access network device includes:

[0081] When a core network multi-flow connection is established between the terminal and the core network device, the terminal determines whether to send the first message according to target information;

[0082] When determining to send the first message, the terminal sends the first message to the access network device;

[0083] The target information includes at least one of the following:

[0084] A split mode of the core network multi-flow connection;

[0085] a connection configuration of the access network device;

[0086] a transmission condition of the first transmission path;

[0087] a transmission condition of the second transmission path;

[0088] The first transmission path is a transmission path where the access network device is located, and the second transmission path is a transmission path other than the first transmission path among the at least two transmission paths.

[0089] In the embodiments of the present application, when the terminal establishes a core network multi-flow connection with the core network device, the terminal can directly send the first message, or the terminal can send the first message when the terminal establishes a core network multi-flow connection with the core network device and the terminal determines that the sending condition of the first message is met based on the target information.

[0090] Optionally, the above-mentioned split mode includes but is not limited to at least one of the following: Active-Standby, SmallestDelay, Load-Balancing, Priority-based, Redundant. When it is determined whether to send the first message based on the split mode, the first message can be triggered to be sent in the case that the split mode option has a greater autonomy for the terminal to select a path. For example, in the modes of Redundant, Smallest Delay, Load-Balancing allowed to be implemented by the UE, etc., the first message can be triggered to be sent.

[0091] Optionally, when it is determined whether to send the first message based on the connection configuration of the access network device, for example, only the active path in the Active-Standby mode can trigger the first message to be sent to the serving cell corresponding to the path; or the high-priority path in the Priority-based mode can trigger the first message to be sent to the serving cell corresponding to the path; or the Primary path configured in the Redundant mode can trigger the first message to be sent to the serving cell corresponding to the path; or only the remaining paths in the above examples can trigger the first message to be sent to the serving cell corresponding to the path, etc.

[0092] Optionally, when it is determined whether to send the first message based on the transmission condition of the first transmission path, for example, the terminal can trigger the first message to be sent in the case that the transmission of the serving cell corresponding to the first transmission path becomes worse or better, such as the data packet delay exceeds a threshold or is lower than a threshold, the data packet block error rate is higher than a threshold or is lower than a threshold, congestion occurs, or congestion is relieved, etc.

[0093] Optionally, when determining whether to send the first message based on the transmission condition of the first transmission path, the terminal can trigger sending the first message when the transmission of the second transmission path corresponding to the serving cell becomes worse or better, such as when the packet delay exceeds or is below a threshold, the packet block error rate is higher or lower than a threshold, congestion occurs, or congestion is alleviated, and the like.

[0094] Optionally, in some embodiments, the first message includes at least one of the following:

[0118] Optionally, the above-mentioned state information can include, but is not limited to, at least one of the following:

[0119] Wireless resource load, such as wireless resource consumption or remaining (such as high, medium, low), or wireless resource occupation or idle percentage;

[0120] Other load, such as storage occupation or remaining (such as high, medium, low), or storage occupation or remaining percentage;

[0121] Computing or processing load, such as computing or processing occupation or remaining (such as high, medium, low), or computing or processing occupation or remaining percentage.

[0122] Optionally, the access network device can make certain suggestions for the shunting of the terminal through its own analysis and operation on the global information, and obtain uplink shunting suggestion information. For example, prefer the current path, or prefer another path, the percentage of the current path, the percentage of another path, whether to copy transmission, etc. Generally, in the case that the current access network device has a lighter load or better link quality, the current path can be preferred as much as possible, or a large percentage of shunting, and even for high QoS services, the access network device can undertake copy transmission. Conversely, the opposite is true, and the use of the current path is avoided and reduced as much as possible.

[0123] It should be noted that the access network device sending the first shunting assistance information to the terminal can be immediately issued, or can be issued after waiting for certain conditions, for example, when the measurement result is normal, for example, when the QoS requirement is met, the first shunting assistance information can be temporarily not issued, and only when the measurement result is abnormal, for example, when the QoS requirement is not met, the first shunting assistance information is issued. When the load of the access network device is high, the access network device state meets a certain threshold, and the first shunting assistance information is issued to the terminal to give an early warning to the path of the access network device, or when the load is light, the first shunting assistance information is issued again to give a hint to the recovery of the path of the access network device. The shunting suggestion is similar. When the resource of the access network device is not in alarm, the shunting suggestion can not be given, and when the resource of the access network device is in alarm, the shunting suggestion is given. The advantage of this is similar to event triggering. Only in extreme cases, the terminal is warned and informed, and the signaling overhead is reduced.

[0124] Of course, in some embodiments, the first shunting assistance information provided by the access network device can also be continuously issued, for example, periodically, or when there is a certain change, that is, issued to the terminal, so that the terminal can better understand the more real-time situation and make better judgments.

[0125] In order to better understand the present application, the following will take two transmission paths as an example and make a detailed description through some examples.

[0126] Embodiment one: the UE sends a first message to the serving base station.

[0127] In a typical high-layer dual connectivity or multi-connectivity, two or more transmission paths are established between a terminal and a core network device for a service. Taking two transmission paths as an example, a typical scenario is, for example, one path is transmitted through 4G and the other path is transmitted through 5G; or in a future scenario, one path is transmitted through 5G and the other path is transmitted through 6G; or one path is transmitted through the network of operator A and the other path is transmitted through the network of operator B; or one path is transmitted through an NTN network and the other path is transmitted through a TN network; or one path is transmitted through a 3GPP 4G, 5G or 6G base station and the other path is transmitted through a non-3GPP technology such as wifi, etc.

[0128] The terminal is responsible for routing of uplink data, and the core network device (for example, UPF) is responsible for routing of downlink data. If the terminal can obtain certain offloading assistance information from the serving base station, it will help the terminal to make better decisions on the routing of uplink data, and thus improve user experience and system efficiency.

[0129] Since dual-flow or multi-flow technology is an optional terminal feature, and terminals supporting this feature will selectively establish a dual-flow or multi-flow transmission mechanism due to different current scenarios, alternative access node conditions, terminal preferences, battery status, service requirements and characteristics, core network policies, etc. These situations are transparent and invisible to the terminal's serving base station. Therefore, the terminal should selectively send a first message to the serving base station to obtain first offloading assistance information in the case of its own dual-flow or multi-flow transmission mechanism being turned on.

[0130] Optionally, since the process of the terminal sending the first message belongs to a new mechanism, the version and capability of the serving base station are required, and therefore the permission and support of the serving base station need to be obtained before the terminal sends the first message.

[0131] The serving base station's permission to send the first message can be notified to the terminal through public signaling and dedicated signaling. The public signaling method, for example, carries a 1-bit flag in an SIB message, indicating that the serving cell supports the sending of the first message. The public signaling method is generally effective for all terminals, unless the public signaling also carries a scope of effectiveness, or the scope of effectiveness is agreed upon. For example, the first message can be sent only for dual-flow services under different RAT base stations of the same operator, or only for 4G and 5G dual-flow or 5G and 6G dual-flow services, or the services that allow the new first message to be sent have specific characteristics, such as meeting certain service QoS requirements. Alternatively, the dedicated signaling method means that after the terminal enters the connected state, the serving cell can issue a dedicated permission to the terminal based on its current situation or terminal status. For example, the dedicated permission is only issued to the terminal when the serving cell's capabilities support the new function, the current cell system load is not high, or the terminal's service meets certain characteristics. Regardless of the method, the terminal can only proceed with the subsequent first message sending process after obtaining permission, avoiding the terminal blindly initiating uplink calls that are not supported by the serving cell, thereby wasting signaling overhead.

[0132] After obtaining the first message sending permission of the serving cell, the terminal may selectively or on demand initiate the first message sending to the serving cell, the main purpose of which is to obtain the first offload auxiliary information of the data offload. The specific triggering method includes at least one of the following:

[0133] When a multi-stream connection is established between the terminal and the core network device, the sending of the first message may be triggered;

[0134] When a multi-stream connection is established between the terminal and the core network device, the sending of the first message can be triggered based on the target information.

[0135] The target information includes at least one of the following:

[0136] A split mode of the core network multi-flow connection;

[0137] The connection configuration of the current serving cell;

[0138] transmission status of the first transmission path;

[0139] transmission condition of the second transmission path;

[0140] The first transmission path is the transmission path of the terminal's current serving cell, and the second transmission path is another transmission path except the first transmission path.

[0141] Optionally, the first message can be triggered to be sent when the multi-flow connection is established between the terminal and the core network device, and a certain condition is met for the split mode of the core network multi-flow connection. For example, the first message can be triggered to be sent in the case that the terminal has a large autonomy for path selection in the split mode option. For example, the first message can be triggered to be sent in the Redundant, Smallest Delay, Load-Balancing allowed to be implemented by the UE, and the like.

[0142] Optionally, the first message can be triggered to be sent when the multi-flow connection is established between the terminal and the core network device, and a certain condition is met for the connection configuration of the terminal and the current serving cell. For example, only the active path in the Active-Standby mode can trigger the first message to be sent to the serving cell corresponding to the path; or the high-priority path in the Priority-based mode can trigger the first message to be sent to the serving cell corresponding to the path; or the primary path configured in the Redundant mode can trigger the first message to be sent to the serving cell corresponding to the path; or only the remaining paths in the above examples can trigger the first message to be sent to the serving cell corresponding to the path, and the like.

[0143] Optionally, the first message can be triggered to be sent when the multi-flow connection is established between the terminal and the core network device, and a certain condition is met for the transmission of the first transmission path. For example, the condition can include that the transmission of the terminal in the current serving cell becomes worse or better, such as that the packet delay exceeds or is lower than a threshold, the packet block error rate is higher or lower than a threshold, congestion occurs, or congestion is alleviated, and the like.

[0144] Optionally, the first message can be triggered to be sent when the multi-flow connection is established between the terminal and the core network device, and a certain condition is met for the transmission of the second transmission path. For example, the condition can include that the transmission of the terminal in another path becomes worse or better, such as that the packet delay exceeds or is lower than a threshold, the packet block error rate is higher or lower than a threshold, congestion occurs, or congestion is alleviated, and the like.

[0145] The above triggering methods can be configured by the network side device, or agreed by the protocol, or determined based on the terminal implementation.

[0146] Further, the UE decides to send the first message to the serving cell to obtain the first split assistance information for data splitting. The specific content of the first message reported can refer to the above embodiments and will not be described here.

[0147] Optionally, in order to avoid the terminal frequently sending the first message, a target timer can be introduced or configured to achieve the implementation, for example, the serving cell configures the timing length of the target timer, and the target timer is started or restarted each time the terminal sends the first message. Before the target timer expires, the first message is not allowed to be sent again. After the target timer expires, it can be decided whether to send the first message as needed, or in the case that no first flow splitting assistance information is received during the running of the target timer, the first message can be re-sent immediately after the target timer expires; or after the target timer expires, it is determined whether to send the first message based on the target information.

[0148] Embodiment two: The serving base station provides flow splitting assistance information to the terminal.

[0149] In this embodiment, it is assumed that the first message in embodiment one has been received, because without this process, the serving base station is not clear which terminal needs which flow splitting assistance information and when.

[0150] The serving base station corresponding to one path of the core network dual-flow mechanism of the terminal can perform at least one of the following behaviors after receiving the first message of the terminal:

[0151] 1. Since the first message of the terminal is only a suggestion to the serving base station, when the serving base station algorithm or the current capability, processing load, etc. does not support it, the serving base station can ignore the request of the terminal, that is, how to handle the request of the terminal depends entirely on the implementation of the serving base station, and is not strictly regulated and limited.

[0152] 2. For the first message of the terminal, the serving base station stores the information, and takes the terminal capability allocation, battery condition, terminal tendency, DRB or QoS flow involved in terminal flow splitting, flow splitting mode, whether the main path, flow splitting ratio, etc. as a powerful basis for subsequent adjustment of terminal scheduling information, and even can occur reconfiguration process of the terminal to better adapt to the current state of the terminal and better meet data transmission and improve system efficiency; for example, if the terminal capability changes, the configuration or scheduling needs to be adapted accordingly to avoid exceeding the capability or timely expanding the upgraded capability; the battery and the terminal tendency will also affect the configuration or scheduling of the terminal to try to meet the terminal demand; the DRB or QoS flow involved in the terminal flow splitting, the flow splitting mode, whether the main path, the flow splitting ratio, etc. help the base station to further understand the data flow situation on its own path, so as to better serve the terminal from the aspects of resource reservation, special configuration and scheduling, etc.

[0153] 3. In the case where the first message contains another path, the information of the other path can also be used as a reference. If there is interface message interaction between the two nodes, further information such as the load and configuration of the opposite base station can be obtained through inter-node messages for each node (per node), or through inter-node messages for each terminal (per UE), interaction can be conducted on how to better execute and make decisions on the diversion of the terminal.

[0154] 4. Send the first offload auxiliary information to the terminal. The content and sending method of the first offload auxiliary information can refer to the above embodiment and will not be repeated here.

[0155] Example 3: Interaction between core network equipment and base stations.

[0156] This embodiment describes the interaction between core network equipment and base stations. Since core network equipment is responsible for routing and offloading downlink data, if the offloading node can obtain the base station's offload auxiliary information (i.e., the second offload auxiliary information), it will help improve path selection, transmission quality, and system efficiency.

[0157] Generally speaking, the node responsible for offloading in the core network is the user plane node, such as UPF, and there is generally no direct interface between the UPF and the base station. In this case, the base station and the core network control node, such as AMF, can interact, and then the core network control node forwards the interaction information to the UPF. Alternatively, in the upgraded core network architecture, the interface between the base station and the core network can be virtualized or the bus mechanism can be upgraded so that the base station can interact directly with the UPF. In short, whether directly or indirectly, the base station and the node responsible for offloading can exchange necessary information. In the following description, the interaction process between the core network offload node and the base station is directly used as an example to illustrate. If transfer is required, the intermediate node transfers it to achieve a similar effect, which will not be repeated.

[0158] First, before core network equipment (i.e., core network offload nodes) and base stations interact, they should ensure that both parties have the upgrade capability. If one party does not upgrade the capability, the interaction cannot proceed. The capabilities of both parties can be understood through a similar process of establishing and interacting capabilities between nodes.

[0159] Secondly, the core network diversion node is generally the first to initiate, because only the core network diversion node knows the situation of the UE establishing a dual-stream data channel, which is equivalent to the initiator of the demand. In particular, the base station may first obtain the request or basic diversion information from the UE. While feeding back the first diversion auxiliary information to the UE, it can also actively feed back some second diversion auxiliary information to the core network diversion node to facilitate the diversion of downlink data.

[0160] The request information content of the core network offloading node can refer to the request content of the UE, wherein in addition to terminal-specific information such as the capability and battery condition of the UE, the remaining information can be contained, in addition, the core network offloading node can also contain additional information, because the core network offloading node is a higher layer node, it can contain more global information or strategy to provide to the base station, for example, some offloading-related detailed strategy, the condition of another path, etc.

[0161] The serving base station receiving the request of the core network offloading node can choose to immediately or subsequently or ignore feeding back the second offloading assistance information to the core network offloading node, the content of the second offloading assistance information can refer to the content of the first offloading assistance information, which will not be described here. The difference between the two is that one is used for uplink offloading control and the other is used for downlink offloading control.

[0162] Finally, the core network offloading node gets the measurement result information, load information, offloading suggestion information, etc. of the serving base station, and comprehensively selects the most suitable one as the current path or the path of the current data packet according to the results of the two paths.

[0163] It should be noted that for GBR services, since the guarantee bit rate and QoS parameters need to be carried during service establishment, the base station needs to reserve sufficient resources for the uplink and downlink of the service according to the guarantee bit rate and QoS parameters to ensure that it can support the guarantee bit rate and QoS parameters of the GBR service, and only then is the establishment successful, and the uplink and downlink data paths are successfully established. Once established, the system resources, especially the wireless resources, have been reserved for the uplink and downlink of the service, and if the uplink and downlink of the service can still change the transmission path at will at this time, it will cause waste of reserved resources or not enough reserved resources. For example, for a GBR service, two paths are established, and if both paths are reserved according to the guarantee bit rate and QoS parameters during establishment, it means that the two paths reserve twice the transmission resources, and if the service only selects one main path for transmission at this time, the auxiliary path resource reservation is completely wasted, and if the service transmits half on the main path and half on the auxiliary path according to the algorithm, half of the resources of both paths are wasted. For example, for a GBR service, two paths are established, and if only the main path is reserved according to the guarantee bit rate and QoS parameters during establishment, and the auxiliary path is not reserved, the subsequent service can only be transmitted on the main path, and once the data packet is offloaded to the auxiliary path, since the auxiliary path has no reserved resources, it may not meet the GBR service rate or QoS requirement. In general, there is a certain contradiction between the static resource reservation of the GBR service and the dynamic path selection mechanism.

[0164] To this end, in the embodiments of the present application, for GBR services, when establishing two paths, first inform the related service nodes of the guaranteed bit rate, QoS parameters and other information, and give a basic percentage or shunting index, for example, the main path is 100%, the auxiliary path is 0%, when the situation changes, for example, the main path is congested, or the QoS of the main path cannot be met, dynamic adjustment can be made, for example, the main path is 100%, the auxiliary path is 100%, then the uplink and downlink can start copy transmission to ensure high QoS, or the main path is 80%, the auxiliary path is 25%, etc., allowing partial shunting to obtain better service experience. The dynamic adjustment of QoS can be performed by using the existing control plane process to change QoS, or by using the interface interaction between the new core network device and the base station.

[0165] It should be noted that when performing dynamic adjustment, the base station can first send a fourth message to the core network device, the fourth message being used to request adjustment of the shunting ratio of the GBR service. Based on the fourth message, the core network device can send target indication information to the base station (corresponding to the two paths), the target indication information being used to indicate adjustment of the shunting ratio of the target service; and the base station performs reserved resource adjustment based on the target indication information.
