[0184] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0185] With the extension of network ecology and the development of network technology, network services are becoming more and more abundant. Diversified services require a Quality of Service (QoS) system mechanism to provide differentiated service guarantees.

[0186] Currently, the 5G communication system has introduced an end-to-end QoS architecture, in which PDU sessions (English: Protocol Data Unit session, referred to as: PDU session) are used to provide end-to-end connection management of the user plane. The basic granularity is refined into QoS flow, and a two-step mapping is used at the non-access layer (English: Non-Access-stratum, referred to as: NAS) level and the access layer (English: Access-stratum, referred to as: AS) level.

[0187] Specifically, for each UE (User Equipment), the core network (CN) will establish one or more PDU sessions. In the NAS-level mapping, each PDU session can contain multiple QoS flows, and each QoS flow corresponds to a set of QoS parameters. In the AS-level mapping, the RAN (Radio Access Network) maps the QoS flow to the data radio bearer (DRB) according to the core network's QoS configuration.

[0188] Specifically, taking the downlink mapping as an example, the mapping between the downlink IP packet and the QoS flow is completed by the user plane function (UPF). The UPF mapping algorithm is called the packet detection rule (PDR). For each IP packet, the PDR checks the packet information (source, destination IP address and port, protocol ID, service type, etc.) defined in the packet filtering configuration and redirects the packet to a specific QoS Flow. The PDR is provided to the UPF by the SMF (Session Management Function) that interacts with the PCF (Policy Control Function). After identifying the appropriate PDU session and QoS flow, the UPF uses the GTP-U (GPRS Tunneling Protocol User Plane) tunnel to forward the data to the 5G base station (gNodeB or gNB)

[0189] The UPF adds an IP header when routing through the GTP-U tunnel, which means that the packet now has two IP headers. They are usually referred to as the inner and outer IP headers. The UPF can use the DSCP (Differentiated Services Code Point) field in the outer IP header to prioritize packets. The headers associated with the GTP-U tunnel are removed at the far end of the tunnel (i.e., the gNB or, if the core network architecture uses linked UPFs, in another UPF).

[0190] The 5G base station uses the GTP-U header information to identify the PDU session and QoS flow associated with the data packet. The RRC layer (English: Radio Resource Control, Chinese: Wireless Resource Control) of the 5G base station instructs the SDAP layer (English: Service Data Adaptation Protocol, Chinese: Service Data Adaptation Protocol) on the mapping rules of QoS flow to DRB according to the QoS configuration received from the core network. After that, the data packet sent from the UPF is processed by the SDAP layer and the data packet is mapped to a specific DRB.

[0191] As mentioned above, in the QoS architecture of the 5G communication system, the access network implements the mapping at the AS level, that is, the access network maps the QoS flow to the DRB. Specifically, the RRC layer of the 5G base station determines the mapping rule of the QoS flow to the DRB according to the QoS configuration issued by the core network, and then the SDAP layer of the 5G base station maps the QoS flow to the DRB according to the mapping rule, thereby realizing the QoS requirements of the service.

[0192] According to the above description, the QoS configuration used by 5G base stations to implement mapping is issued by the core network. Generally speaking, the QoS configuration is determined by the core network side based on the QoS requirements of the service and the user's contract information and issued to the access network side. However, in some cases, the network capabilities of the access network cannot match the QoS requirements of the service, which leads to inappropriate QoS configuration issued by the core network side to the access network, resulting in various problems such as inefficient network operation.

[0193] In view of this, an embodiment of the present application provides a service quality adjustment method, apparatus, device and storage medium, which obtains service wireless information from an access network network node through an access network control node, and sends auxiliary configuration information to the core network side based on the service wireless information, wherein the access network network node includes at least one of the following nodes: an access network control node, an access network data node and a virtual node on the access network side. In this way, the access network control node can report the auxiliary configuration information to the core network side based on the service wireless information collected from multiple types of nodes on the access network side, so that the core network side can issue a QoS configuration that can be adapted to the network capabilities of the access network based on the auxiliary configuration information, thereby avoiding problems such as inefficient network operation to a certain extent.

[0194] It should be noted that the beneficial effects brought about by the embodiments of the present application or the technical problems solved are not limited to this one, but may also include other implicit or related problems.

[0198] Figure 3The access network architecture shown is a user-centric access network architecture. By introducing flexible cells, multiple TRPs under the jurisdiction of DDU are organized to coordinate transmission and serve one UE, thereby improving the user experience. Figure 3 As shown, a flexible cell serving the UE is composed of multiple TRPs, where the functions of each network element are introduced as follows: CCU, responsible for control and management functions; DDU, for data scheduling and transmission; TRP, responsible for radio frequency and part of the physical layer functions.

[0199] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0200] In one embodiment, Figure 4 As shown, a method for adjusting quality of service is provided, which is described by taking the method applied to an access network control node as an example, and includes the following steps:

[0201] Step 401: The access network control node obtains service wireless information from the access network node.

[0202] In an optional embodiment of the present application, the service wireless information may reflect the network capability of the access network. In an optional embodiment of the present application, the service wireless information may reflect the real-time status of the resource status, air interface change, etc. of the access network side. In an optional embodiment of the present application, the service wireless information may reflect whether the network capability of the access network can match the QoS requirements of the service.

[0203] In an optional embodiment of the present application, the access network control node may periodically obtain service wireless information from the access network network node, or the access network control node may obtain service wireless information from the access network network node in response to an instruction from the core network side, or the access network control node may obtain service wireless information from the access network network node according to the network configuration, or the access network control node may perform the step of obtaining service wireless information from the access network network node when certain conditions are met, for example, the access network control node may perform the step of obtaining service wireless information from the access network network node when the state of the access network network node meets certain conditions.

[0204] In an optional embodiment of the present application, the access network network node may include at least one of the following nodes: an access network control node, an access network data node, and a virtual node on the access network side.

[0205] Step 402: The access network control node sends auxiliary configuration information to the core network side according to the service wireless information.

[0206] In an optional embodiment of the present application, the auxiliary configuration information can be used by the core network side to determine the QoS configuration based on the auxiliary configuration information.

In this way, the access network control node can report the auxiliary configuration information to the core network side according to the service wireless information collected from multiple types of nodes on the access network side, so that the core network side can issue a QoS configuration that can adapt to the network capability of the access network based on the auxiliary configuration information, thereby avoiding problems such as inefficient network operation to a certain extent.

[0209] In addition, in the existing implementation method, the access network side can only notify the core network that the QoS requirements of the established GBR (Guaranteed Bit Rate) QoS flow are no longer met or are met again, and the information sent by the access network side to the core network side is relatively single and simple. However, in the technical solution provided in the embodiment of the present application, the access network control node can collect service wireless information from multiple types of access network nodes, and report auxiliary configuration information to the core network side based on the service wireless information, so that the core network side can determine the network capabilities of the access network side based on the auxiliary configuration information, and thus can issue QoS configurations that can be adapted to the network capabilities of the access network based on the auxiliary configuration information. Compared with the existing implementation method, the information sent by the access network side to the core network side is richer and more diversified.

[0210] In an optional embodiment of the present application, the access network control node includes at least one of the following nodes: a CU, a control plane CU-CP of the CU, and a CCU.

[0216] The node load information is used to characterize the load of the node, for example, the load of the access network control node, the load of the access network network node, the load of the virtual node on the access network side, etc. The UE-level information includes information related to the UE. The QoS flow-level information includes information related to the QoS flow. The DRB-level information includes information related to the DRB.

Among them, the cell measurement information at least includes at least one of radio resource load information (the radio resource load information is used to indicate whether the radio resource is used, or the radio resource load information is used to indicate whether the radio resource is idle), the number of RRC connections and the number of PDU sessions.

[0218] In an optional embodiment of the present application, the information at the UE level includes at least one of the following: UE throughput, UE packet delay, UE packet loss rate, UE location information, UE retransmission information, access network network node serving the UE in the access network (in some embodiments, may be referred to as collaborative information) and measurement information reported by the UE.

[0221] In an optional embodiment of the present application, the protocol status information includes at least one of high-layer protocol status information and physical layer protocol status information.

[0222] Among them, in an optional embodiment of the present application, the high-level protocol status information includes at least one of the following contents: a buffer status report, a retransmission configuration and an RLC (English: Radio Link Control; Chinese: Wireless Link Layer Control Protocol) status report configuration of the high-level protocol.

[0223] In an optional embodiment of the present application, the physical layer protocol status information includes at least one of the following: PRB (English: Physical Resource Block; Chinese: physical resource block) utilization rate and TB (English: Transport Block; Chinese: transport block) measurement information.

[0224] In an optional embodiment of the present application, the TRP information includes at least one of the following: the number of TRPs, the available frequency of the TRPs, and the bandwidth of the TRPs.

[0225] In an optional embodiment of the present application, the access network control node sends the auxiliary configuration information to the core network side according to the service wireless information, including at least one of the following methods:

[0226] In the first mode, the access network control node sends the service wireless information as auxiliary configuration information to the core network side.

[0227] For example, for the retransmission information, radio resource load information, etc. of the UE, the access network control node can directly send it to the core network side as auxiliary configuration information.

[0228] In the second manner, the access network control node processes the service wireless information to obtain processed service wireless information, and sends the processed service wireless information to the core network side as auxiliary configuration information.

[0229] In the third mode, the access network control node obtains QoS requirement information according to the service wireless information, and sends the QoS requirement information to the core network side as auxiliary configuration information.

[0230] The QoS requirement information is used to instruct the core network side to adjust the QoS configuration based on the QoS requirement information, or to instruct the core network side to determine the QoS configuration based on the QoS requirement information.

[0231] In an optional embodiment of the present application, the access network control node processes the service wireless information to obtain the processed service wireless information, including at least one of the following methods:

[0232] In the first mode, the access network control node performs statistical processing on the service wireless information and uses the statistical processing result as the processed service wireless information.

[0233] For example, the access network control node may perform statistical processing such as averaging, maximum value, minimum value, maximum value, and minimum value on the parameters in the service wireless information, and then use the statistical processing results as the processed service wireless information.

[0234] In the second manner, the access network control node compares the service wireless information with a preset threshold value, and uses the comparison result as the processed service wireless information.

[0235] For example, the access network control node may compare the parameters in the service wireless information with a preset threshold, and obtain a comparison result greater than the preset threshold, less than the preset threshold, or equal to the preset threshold. The access network control node may use the comparison result as the processed service wireless information.

[0236] In the third manner, the access network control node screens the service wireless information according to a preset threshold value, and uses the screened service wireless information as the processed service wireless information.

[0237] For example, the access network control node may filter parameters greater than a preset threshold, or filter parameters less than a preset threshold, or filter parameters equal to the preset threshold from the parameters in the service wireless information, and use the filtered parameters as the processed service wireless information.

[0238] In a fourth manner, the access network control node calculates and processes the service wireless information according to a preset algorithm, and uses the calculated result as the processed service wireless information.

[0239] Optionally, the access network control node may calculate and process the service wireless information according to a preset algorithm to obtain the wireless transmission efficiency of the service, and use the wireless transmission efficiency as the processed service wireless information.

[0240] For example, the access network control node can calculate and process the service wireless information according to a preset algorithm to obtain the wireless transmission efficiency of the QoS flow (the wireless transmission efficiency may be the spectrum efficiency), and use the wireless transmission efficiency of the QoS flow as the processed service wireless information.

[0241] In a fifth manner, the access network control node determines the first access network data node information according to the service wireless information and the instruction of the core network side, and uses the first access network data node information as the processed service wireless information.

[0242] When the communication network performs data diversion based on UPF sinking and / or based on MEC (English: Mobile Edge Computing; Chinese: Edge Computing) technology, the access network control node can receive indication information sent by the core network side, and determine the first access network data node information based on the indication information and the service wireless information, and use the first access network data node information as the processed service wireless information.

[0243] Optionally, the first access network data node information is used to indicate an access network data node selected from multiple access network data nodes for business data transmission, that is, the first access network data node information is used to indicate a suitable access network data node selected from multiple access network data nodes, and the suitable access network data node can be used for subsequent business data transmission.

[0244] In an optional embodiment of the present application, the access network control node obtains the QoS requirement information according to the service wireless information in at least one of the following ways:

[0245] In the first mode, the access network control node determines the recommended QoS parameters from the candidate QoS parameter set sent from the core network side according to the service wireless information, and uses the recommended QoS parameters as the QoS requirement information.

[0246] Optionally, the core network side may send an alternative QoS parameter set (English: Alternative QoS Parameters Set) to the access network control node, and the access network control node may determine a recommended QoS parameter (English: QoS Parameters Set Index) from the alternative QoS parameter set based on the service wireless information to request the core network side to take effect on the recommended QoS parameter.

[0247] For example, the access network control node can determine the transmission efficiency, resource occupancy, etc. of the service based on the service wireless information, and then, the access network control node can determine the recommended QoS parameters from the alternative QoS parameter set based on the transmission efficiency, resource occupancy, etc. of the service to require the core network side to take effect on the recommended QoS parameters.

[0248] The second method is that for services that the access network cannot meet the corresponding QoS requirements, the access network control node generates a PDU session anchor switching request and the second access network data node information based on the service wireless information, and uses the PDU session anchor switching request and the second access network data node information as QoS requirement information.

[0249] Optionally, the access network control node can determine whether the network capability of the access network can meet the QoS requirements of different services based on the service wireless information, thereby determining the services for which the access network is difficult to meet the corresponding QoS requirements from the different services. For example, a certain service has high requirements for the packet delay budget (English: packet delay budget; abbreviated as: PDB), and the access network control node determines based on the service wireless information that the network capability of the access network is difficult to meet the packet delay budget requirements of the service, then the access network control node can determine that the network capability of the access network is difficult to meet the QoS requirements corresponding to the service. In this case, the access network control node may not need the instruction of the core network, but actively generate a PDU session anchor switching request and the second access network data node information for the service to meet the QoS requirements of the service as much as possible.

[0250] Among them, the PDU session anchor point switching request is used to request switching the anchor point of the PDU session. For example, the PDU session anchor point switching request can request to switch the anchor point of the PDU session to an edge UPF or a dynamically deployed distributed UPF. The second access network data node information is used to indicate an access network data node selected from multiple access network data nodes for service data transmission, that is, the second access network data node information is used to indicate a suitable access network data node selected from multiple access network data nodes, and the suitable access network data node can be used for subsequent service data transmission.

[0251] In the third manner, the access network control node generates QoS requirement information for a target period before mobility switching of the UE occurs according to the service radio information.

[0252] Optionally, the access network control node can determine the time when the UE undergoes mobility switching based on the UE location information in the service wireless information, and then the access network control node can generate QoS requirement information for the target time period before the UE undergoes mobility switching based on the time when the UE undergoes mobility switching, so as to request the core network side to improve the QoS requirements of the service within the target time period before the UE undergoes mobility switching, for example, to improve the latency of the service, guarantee the rate, etc., thereby ensuring that the QoS of the service can be guaranteed within the target time period before the UE undergoes mobility switching.

[0253] It should be noted that the target period may include a period during which the UE performs handover preparation and a period during which the UE performs handover.

[0254] In a fourth manner, the access network control node selects a target QoS requirement from multiple sets of QoS requirements configured on the core network side according to the service wireless information, and uses the indication information of the target QoS requirement as the QoS requirement information.

[0255] In an optional embodiment of the present application, the core network side may configure multiple sets of QoS requirements to the access network control node. For example, the core network side may configure multiple sets of QoS requirements to the access network control node in the form of a policy and charging control rule (English: Policy and Charging Control Rule; abbreviated as: PCC Rule). The access network control node may select a target QoS requirement from the multiple sets of QoS requirements configured on the core network side according to the service wireless information, and send the indication information of the target QoS requirement as QoS requirement information to the core network side to require the core network to execute the target QoS requirement.

[0256] In an optional embodiment of the present application, the access network control node may also determine the effective time of each of multiple sets of QoS requirements configured on the core network side according to the service wireless information, and make different sets of QoS requirements effective at different times based on the determined effective time.

[0257] In an optional embodiment of the present application, the access network control node may send the auxiliary configuration information to the core network side in at least one of the following ways:

[0258] In the first manner, the access network control node sends auxiliary configuration information to the core network side in response to a request from the core network side.

[0259] In the second mode, the access network control node periodically sends auxiliary configuration information to the core network side.

[0260] The third method is that when the reporting conditions are met, the access network control node sends auxiliary configuration information to the core network side.

[0261] In an optional embodiment of the present application, the auxiliary configuration information may be carried by a first message, or may be carried by a second message.

[0262] The first message is a message between the access network control node and the core network side defined by 3GPP, and optionally, a new information element may be added to the first message to use the new information element to carry the auxiliary configuration information. The second message is a newly defined message between the access network control node and the core network side.

[0263] In the case where the auxiliary configuration information is carried by the first message, for example, the auxiliary configuration information may be carried by a PDU session resource notification message; and / or carried by a PDU session resource establishment response message.

[0264] Please refer to Figure 5 , which is an optional schematic diagram of the first message carrying auxiliary configuration information, such as Figure 5 As shown, the core network side can carry multiple sets of QoS requirements in the PDU session resource establishment request message (English: PDU Session Resource Setup Request), and the access network control node can carry the QoS requirements (that is, auxiliary configuration information) selected from the multiple sets of QoS requirements in the PDU session resource establishment response message (English: PDU Session Resource Setup Response).

[0265] Please refer to Figure 6 , which is an optional schematic diagram of the first message carrying auxiliary configuration information, such as Figure 6 As shown, the access network control node can carry auxiliary configuration information in a PDU session resource notification message (English: PDU Session Resource Notify), the core network side can update the QoS requirements based on the auxiliary configuration information, and carry the updated QoS requirements in a PDU session resource modification request message (English: PDU Session Resource Modify Request). If the PDU session resource modification request message carries multiple sets of updated QoS requirements, the access network control node can carry the QoS requirements (that is, the auxiliary configuration information) selected from the multiple sets of updated QoS requirements in a PDU session resource modification response message (English: PDU Session Resource Modify Response).

[0266] Please refer to Figure 7, which is an optional schematic diagram of the second message carrying auxiliary configuration information, such as Figure 7 As shown, the access network control node can carry auxiliary configuration information in the access network QoS reporting message (English: RAN QoS Report), the core network side can update the QoS requirements based on the auxiliary configuration information, and carry the updated QoS requirements in the PDU session resource modification request message. If the PDU session resource modification request message carries multiple sets of updated QoS requirements, the access network control node can carry the QoS requirements (that is, the auxiliary configuration information) selected from the multiple sets of updated QoS requirements in the PDU session resource modification response message.

[0267] Please refer to Figure 8 , which is an optional schematic diagram of the second message carrying auxiliary configuration information, such as Figure 8 As shown, the core network side can carry the core network configuration, for example, QoS requirements, reporting configuration of auxiliary configuration information, etc. in the access network QoS reporting request message (English: RAN QoS Report Request), and the access network control node can carry the auxiliary configuration information in the access network QoS reporting response message (English: RAN QoS Report Response). The core network side can update the QoS requirements based on the auxiliary configuration information and carry the updated QoS requirements in the PDU session resource modification request message. If the PDU session resource modification request message carries multiple sets of updated QoS requirements, the access network control node can carry the QoS requirements (that is, the auxiliary configuration information) selected from the multiple sets of updated QoS requirements in the PDU session resource modification response message.

[0268] In an optional embodiment of the present application, the access network control node may also execute the following Fig. 9 The steps shown are as follows Fig. 9 As shown, the step includes:

[0269] Step 901: The access network control node receives the QoS configuration sent by the core network side based on the auxiliary configuration information.

[0270] The QoS configuration in step 901 may be a QoS configuration updated by the core network side based on the auxiliary configuration information, or the QoS configuration in step 901 may be a QoS configuration determined by the core network side based on the auxiliary configuration information.

[0271] As described above, the QoS configuration may be a QoS configuration for a certain service, or a QoS configuration for multiple services, or other types of QoS configurations, which are not specifically limited in the embodiments of the present application. Figures 5 to 8 As shown, the QoS configuration can be carried in the PDU session resource modification request message.

[0272] Step 902: The access network control node configures the access network network node according to the QoS configuration, so as to perform data transmission according to the QoS requirement corresponding to the QoS configuration.

[0273] In one embodiment, Fig.10 As shown, a method for adjusting quality of service is provided, which is described by taking the method applied to a target network element on the core network side as an example, and includes the following steps:

[0274] Step 1001: A target network element receives auxiliary configuration information sent by an access network control node.

[0275] It should be noted that the target network element may be a network element in the core network, or the target network element may be a network element set of multiple network elements in the core network.

[0276] Step 1002: The target network element sends QoS configuration to the access network control node according to the auxiliary configuration information.

[0277] Optionally, the QoS configuration may be a QoS configuration updated by the target network element based on the auxiliary configuration information, or the QoS configuration may be a QoS configuration determined by the target network element based on the auxiliary configuration information.

[0278] As described above, the QoS configuration may be a QoS configuration for a certain service, or a QoS configuration for multiple services, or other types of QoS configurations, which are not specifically limited in the embodiments of the present application.

[0282] The above contents of the embodiments of the present application have been described in detail in the embodiments corresponding to the access network control node. In order to avoid redundancy, the embodiments of the present application will not be described in detail here. The reader can refer to the relevant description in the embodiments corresponding to the access network control node.

[0283] In order to make it easier for readers to understand the technical solutions provided by the embodiments of the present application, four optional embodiments are provided below to exemplarily illustrate the technical solutions provided by the embodiments of the present application.

[0284] Please refer to Fig.11 , which is a flow chart corresponding to the first embodiment, such as Fig.11 As shown, the following steps are included:

[0285] Step 1101: UE registers in the core network and initiates a target service.

[0286] Step 1102: The core network establishes a PDU session for the UE to transmit the service data of the target service, and sends the QoS configuration of the target service to the CU.

[0287] Step 1103: The CU performs data transmission configuration for the DU according to the QoS configuration sent by the core network, so that the DU performs data transmission and scheduling guarantee according to the QoS requirements of the target service.

[0288] Step 1104: The service data of the target service is transmitted between the UE and the core network according to the QoS requirements of the target service.

[0289] Step 1105: The CU obtains service wireless information from itself and the DU.

[0290] For example, the CU can collect network configuration information, data information generated by CU operation, data information generated by DU operation, etc. from itself and the DU.

[0291] Step 1106: The CU reports the service wireless information as auxiliary configuration information to the core network.

[0292] Step 1107: The core network adjusts the QoS configuration of the target service according to the auxiliary configuration information, and sends the updated QoS configuration to the CU.

[0293] For example, when the QoS requirements of the target service are high and the access network can meet the QoS requirements, but the target service occupies more wireless resources of the access network and has low efficiency (such as more retransmissions, higher packet error rate, more packet loss, and higher wireless resource load), in this case, the core network can lower the QoS requirements of the target service and generate an updated QoS configuration and send it to the CU.

[0294] Step 1108: The CU performs data transmission configuration for the DU according to the updated QoS configuration sent by the core network, so that the DU performs data transmission and scheduling guarantee according to the updated QoS requirements of the target service.

[0295] Step 1109: The UE and the core network transmit service data of the target service according to the updated QoS requirement of the target service.

[0296] Please refer to Fig.12 , which is a flow chart corresponding to the second embodiment, such as Fig.12 As shown, the following steps are included:

[0297] Step 1201: UE registers in the core network and initiates a service.

[0298] Step 1202: The core network establishes a PDU session for the UE and sends the QoS configuration of the service to the CCU.

[0299] Step 1203: The CCU performs data transmission configuration for the DDU according to the QoS configuration sent by the core network, so that the DDU performs data transmission and scheduling guarantee according to the QoS requirements of the service.

[0300] Step 1204: Data is transmitted between the UE and the core network according to the QoS requirements of the target service.

[0301] Step 1205: The CCU obtains service wireless information from itself and the DDU.

[0302] For example, the CCU can collect network configuration information, data information generated by CCU operation, data information generated by DDU operation, etc. from itself and the DDU.

[0303] Step 1206: The CCU processes the service wireless information and reports the processed service wireless information to the core network as auxiliary configuration information.

[0304] For example, the CCU calculates the average spectral efficiency of the QoS flow of each service based on the transmission rate of the QoS flow of each service in the service wireless information and the resource occupancy information of the QoS flow. Then, the CCU determines the service whose average spectral efficiency of the QoS flow is lower than the average spectrum threshold and the corresponding access network node has fewer idle resources as the target service, and reports the identifier of the target service to the core network as auxiliary configuration information.

[0305] Step 1207: The core network adjusts the QoS configuration of the target service according to the auxiliary configuration information, and sends the updated QoS configuration of the target service to the CCU.

[0306] Optionally, the core network may lower the QoS requirements of the QoS flow of the target service to obtain an updated QoS configuration for the target service. In this way, the wireless resources occupied by QoS flows with lower average spectral efficiency can be reduced, and the free wireless resources can be allocated to other services, thereby improving overall efficiency.

[0307] Step 1208: The CCU performs data transmission configuration for the DDU according to the updated QoS configuration sent by the core network, so that the DDU performs data transmission and scheduling guarantee according to the updated QoS requirements of the target service.

[0308] Step 1209: The UE and the core network transmit service data of the target service according to the updated QoS requirement of the target service.

[0309] Please refer to Fig.13 , which is a flow chart corresponding to the third embodiment, such as Fig.13 As shown, the following steps are included:

[0310] Step 1301: UE registers in the core network and initiates a target service.

[0311] Step 1302: The core network establishes a PDU session for the UE for transmitting service data of the target service, and sends the QoS configuration of the target service to the CCU.

[0312] Step 1303: The CCU performs data transmission configuration for the DDU according to the QoS configuration sent by the core network, so that the DDU performs data transmission and scheduling guarantee according to the QoS requirements of the target service.

[0313] Step 1304: The service data of the target service is transmitted between the UE and the core network according to the QoS requirements of the target service.

[0314] Step 1305: The CCU obtains service wireless information from itself and the DDU.

[0315] For example, the CCU can collect network configuration information, data information generated by CCU operation, data information generated by DDU operation, etc. from itself and the DDU.

[0316] Step 1306: The CCU generates QoS requirement information of the target service according to the service wireless information and sends it to the core network to instruct the core network to adjust the QoS configuration of the target service.

[0317] Optionally, the CCU may determine the recommended QoS parameters of the target service from a set of candidate QoS parameters sent from the core network according to the service wireless information, and use the recommended QoS parameters as the QoS requirement information.

[0318] Optionally, the CCU can determine the measurement information of the QoS requirements of the target service, the DDU node load information, the transmission information of the target service (such as the number of retransmissions, spectrum efficiency), etc. based on the service wireless information, so as to determine the recommended QoS parameters of the target service from the set of alternative QoS parameters issued by the core network.

[0319] Optionally, the CCU may add a new information element in the PDU session resource notification message to use the newly added information element to carry the QoS requirement information. Taking the TS38.331 PDU Session Resource Notify Transfer message as an example, the newly added information element may be shown in Table 1.

[0320] Table 1

[0321]

[0322] Among them, the first column in Table 1 indicates the name of the information element. As shown in Table 1, the name of the newly added information element is the recommended QoS parameter set index. The second column in Table 1 indicates whether the information element is required. As shown in Table 1, the newly added information element is optional (O). The third column in Table 1 indicates the value range of the information element. The fourth column in Table 1 indicates the type and reference information of the information element. As shown in Table 1, the type corresponding to the newly added information element is the alternative QoS parameter setting notification index. The fifth column in Table 1 indicates the description information of the information element. As shown in Table 1, the description information corresponding to the newly added information element is the service quality parameter index currently recommended by NG-RAN.

[0323] Step 1307: The core network adjusts the QoS configuration of the target service according to the auxiliary configuration information, and sends the updated QoS configuration of the target service to the CCU.

[0324] Optionally, the core network can lower the QoS requirements of the target service based on the recommended QoS parameters to obtain an updated QoS configuration of the target service. In this way, the target service can release the occupied wireless resources, which can be allocated to other services, thereby improving the overall efficiency of the system.

[0325] Step 1308: The CCU performs data transmission configuration for the DDU according to the updated QoS configuration sent by the core network, so that the DDU performs data transmission and scheduling guarantee according to the updated QoS requirements of the target service.

[0326] Step 1309: The UE and the core network transmit service data of the target service according to the updated QoS requirement of the target service.

[0327] Please refer to Fig.14 , which is a flow chart corresponding to the fourth embodiment, such as Fig.14 As shown, the following steps are included:

[0328] Step 1401: The UE registers in the core network and initiates a delay-sensitive target service.

[0329] Step 1402: The core network establishes a PDU session for the UE for transmitting service data of the target service, and sends the QoS configuration of the target service to the CCU.

[0330] Step 1403: The CCU performs data transmission configuration for the DDU according to the QoS configuration sent by the core network, so that the DDU performs data transmission and scheduling guarantee according to the QoS requirements of the target service.

[0331] Step 1404: The service data of the target service is transmitted between the UE and the core network according to the QoS requirements of the target service.

[0332] Step 1405: The CCU obtains service wireless information from itself and the DDU.

[0333] For example, the CCU can collect network configuration information, data information generated by CCU operation, data information generated by DDU operation, etc. from itself and the DDU.

[0334] Step 1406: When the CCU determines, based on the wireless information of the service, that the network capability of the access network cannot meet the QoS requirements of the target service, the CCU optimizes the configuration of the access network to reduce the latency of the target service.

[0335] Step 1407: If, after optimizing the configuration of the access network, the network capability of the access network still cannot meet the QoS requirement of the target service, the CCU reports the information that the QoS requirement of the target service cannot be met to the core network.

[0336] Step 1408: The core network adjusts the QoS configuration of the target service and sends the updated QoS configuration to the CCU.

[0337] Step 1409: The CCU performs data transmission configuration for the DDU according to the updated QoS configuration sent by the core network, so that the DDU performs data transmission and scheduling guarantee according to the updated QoS requirements of the target service.

[0338] Step 1410: The UE and the core network transmit service data of the target service according to the updated QoS requirement of the target service.

[0339] Step 1411: The CCU obtains service wireless information from itself and the DDU.

[0340] For example, the CCU can collect network configuration information, data information generated by CCU operation, data information generated by DDU operation, etc. from itself and the DDU.

[0341] Step 1412: The CCU generates QoS requirement information of the target service according to the service wireless information, and sends the QoS requirement information to the core network as auxiliary configuration information.

[0342] For example, if the CCU determines based on the service wireless information that the capacity of the access network still cannot meet the QoS requirements of the target service, the CCU generates a PDU session anchor point switching request and the second access network data node information based on the node load status of the collaborative DDU providing services to the UE in the service wireless information, the protocol status information, the UE location information, and the measurement information reported by the UE, and uses the PDU session anchor point switching request and the second access network data node information as the QoS requirement information.

[0343] Among them, the PDU session anchor point switching request is used to request switching the anchor point of the PDU session of the target service, and the second access network data node information is used to indicate the access network data node selected from multiple access network data nodes for target service data transmission. For example, the PDU session anchor point switching request can request to switch the anchor point of the PDU session of the target service to a dynamically deployed distributed UPF or a target UPF provided by the core network, and the second access network data node information can indicate the most suitable DDU ID for carrying the target service from the UPF.

[0344] Step 1413: The core network adjusts the QoS configuration of the target service according to the auxiliary configuration information, and sends the updated QoS configuration of the target service to the CCU.

[0345] For example, the core network may send a message agreeing to switch UPF, which includes target UPF information. In subsequent steps, the CCU may initiate a path switch process after receiving the message, and the DDU switches to the target UPF for data transmission of the target service.

[0346] It should be understood that although Figure 4-14 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders.
