Description

Method, apparatus, terminal and access network device for transmitting service data

[0001] The present disclosure claims priority from a Chinese patent application No. 202411291817.9 filed on September 14, 2024, and entitled "Method, apparatus, terminal and access network device for transmitting service data", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of communication, and particularly relates to a service data transmission method, apparatus, terminal and access network device. BACKGROUND

[0003] Immersive communication represented by extended reality (XR) is an important service requirement of the sixth generation (6G). The traffic pattern of XR service dynamically changes based on the use scenario and application. For example, the media frame size can quickly change due to the initial start of the service or the user dragging the service process. The service characteristics can significantly change in the file download of an artificial intelligence (AI) model update.

[0004] The current quality of service (QoS) configuration and notification mechanism of the fifth generation (5G) cannot adapt to the dynamic change requirement of immersive communication. For downlink immersive services, the notification and feedback mechanism based on alternative QoS profiles can partially solve the requirement of dynamic change of services, but for uplink services, the 5G QoS mechanism cannot timely reflect the change of services, thereby causing a delay in the change of service requirements of the wireless transmission network and affecting the performance of the service.

Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present disclosure.

[0142] The terms "first", "second", and the like in the specification and claims of the present disclosure are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in other sequences than those illustrated or described herein. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0143] In the embodiments of the present disclosure, the term "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects. In the embodiments of the present disclosure, the term "a plurality of" means two or more, and other quantifiers are similar.

[0144] In the embodiments of the present disclosure, the words "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present disclosure should not be interpreted as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0145] The related concepts mentioned in the present disclosure will be briefly described as follows.

[0146] In 5G system, the core network performs the mapping of Service Data Flow (SDF) (e.g. Internet Protocol (IP) flow or Ethernet flow) to Quality of Service (QoS) flow, and the access network performs the mapping of QoS flow to Data Radio Bearer (DRB).

[0147] The mapping of SDF to QoS flow is controlled by core network elements. In downlink direction, the User Plane Function (UPF) of core network performs the mapping of SDF to QoS flow, and the mapping rule is sent to UPF by Session Management Function (SMF); in uplink direction, the mapping of SDF to QoS flow is performed by terminal, and the mapping rule is sent to terminal by core network through Non-Access-Stratum (NAS) message. QoS flow is associated with QoS profile, QoS rule and Packet Detection Rule (PDR). PDR has downlink PDR and uplink PDR, and contains a series of parameters such as source interface, UE IP address, IP multimedia address, SDF filter, QoS Flow identifier (QFI), etc. to realize the mapping of service flow to QoS flow. FIG. 1 is a schematic diagram of SDF to QoS flow classification and mapping.

[0148] The SMF of the core network sends the QoS Profile of each QoS flow to the base station. The QoS profile corresponds to the QoS parameter of the QoS flow. The QoS parameter includes: 5G QoS Identifier (5G QoS Identifier, 5QI), 5QI corresponds to specific parameters such as Packet Delay Budget (PDB), Packet Error Rate (PER), etc.; Allocation and Retention Priority (ARP); the Guaranteed Flow Bit Rate (GFBR) and the Maximum Flow Bit Rate (MFBR) of the Granted Bit Rate (GBR) QoS Flow; the Reflective QoS Attribute (RQA) of the Non-GBR (NGBR) QoS Flow, etc. Each QoS profile has a corresponding QFI, and the QFI is used to identify a QoS flow.

[0149] The base station performs mapping of the QoS flow to the DRB, specifically: determining the QoS requirement of the QoS flow according to the QoS profile of the QoS flow, and mapping the QoS flows with the same QoS requirement to one DRB, that is, performing mapping of the QoS flow to the DRB. The terminal receives the NAS message of the core network, obtains the QoS Rule (including QFI, Packet Filter Set) and QoS parameter; receives the base station configuration, obtains the access network configuration, and performs data transmission according to the resource scheduling of the base station.

[0150] 5G has a reflective QoS mechanism for NGBR services.

[0151] Specifically, the behavior of the core network mainly includes: mapping of IP flow or Ethernet flow to QoS flow, and in the case that the SMF does not provide QoS rules through signaling, the UE can derive QoS rules based on the received downlink data, and map uplink user plane data to the QoS flow through reflective QoS. The parameters used by the UE to derive the QoS rules are the uplink packet filter and the QFI. When the 5G core network wants to use reflective QoS for a specific QoS flow SDF, the SMF provides the RQA of the QoS configuration of this QoS flow to the base station, and in the transmission of user plane data, the UPF sets the reflective QoS indication (Reflective QoS Indication, RQI) parameter of the N3 packet header when packaging each downlink data packet corresponding to the SDF. The base station includes the RQI in the protocol data unit (Protocol Data Unit, PDU) of the service data adaptation protocol (Service Data Adaptation Protocol, SDAP) of the access network. When the UE receives the downlink data packet with RQI, it will derive a QoS rule from the downlink data packet and apply it to the processing of the uplink data packet. If the QFI of the reflective QoS derived from the downlink data packet is different from the previously derived QFI, the new QFI is updated in the QoS rule derived by the UE.

[0152] The behavior of the access network mainly includes: QoS flow to DRB mapping is implemented through the SDAP layer. The base station includes reflective QoS flow to DRB mapping indication (Reflective QoS flow to DRB mapping Indication, RDI) and RQI in the downlink SDAP data PDU to indicate reflective QoS. RQI is used to indicate whether to update the SDF to QoS flow mapping rule to the NAS layer. RDI is used to indicate whether to update the QoS flow to DRB mapping rule. When the terminal receives the downlink SDAP PDU with RDI = 1, it changes the QoS flow to DRB mapping, specifically, applies the correspondence between the QFI of the downlink data packet and the DRB ID (i.e., the DRB ID and QFI carrying the downlink data packet) to the uplink transmission.

[0153] The 5G QoS mechanism cannot adapt to the dynamic change requirements of immersive services, especially for uplink services. The 5G QoS mechanism cannot respond to service changes in a timely manner, which will cause a delay in the change of service requirements of the wireless transmission network, resulting in an impact on service performance.

[0154] Embodiments of the present disclosure are described below with reference to the accompanying drawings. The service data transmission method, apparatus, terminal and access network device provided by the embodiments of the present disclosure can be applied in a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as 5G system), and those skilled in the art can understand that the 5G NR system is only an example and is not limited.

[0155] Referring to FIG. 2, FIG. 2 is a structural diagram of a network system to which embodiments of the present disclosure can be applied. As shown in FIG. 2, the network system includes a user terminal 11 and a base station 12. The user terminal 11 can be a user equipment (User Equipment, UE), such as a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device), and the like. It should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present disclosure. The base station 12 can be a base station of 5G and later versions (for example, a 5G base station (gNB), a 5G NR base station (NodeB, NB)), or a base station in other communication systems, or a node B. It should be noted that the 5G base station is only an example in the embodiments of the present disclosure, and the specific type of the base station 12 is not limited.

[0156] The embodiments of the present disclosure provide a service data transmission method, apparatus, terminal and access network device, so that the QoS mechanism can reflect the service change in time and avoid the delay of the wireless transmission network to the service demand change.

[0157] The method and the apparatus are based on the same application concept. Since the principles of the method and the apparatus for solving problems are similar, the implementation of the apparatus and the method can be referred to each other, and the repeated parts will not be described again.

[0158] As shown in FIG. 3, the embodiments of the present disclosure provide a service data transmission method, which is executed by a terminal and includes the following steps.

[0159] In step S301, it is determined that the service demand of the uplink service changes.

[0160] In some embodiments, the service demand refers to the service transmission characteristics, which can be understood as the QoS attribute, and can also be referred to as the QoS demand. For example, the service demand can be the value requirement of the PDB, PER and the like, that is, different service demands correspond to different parameter values.

[0162] In some embodiments, this step is a case where the service requirement of the uplink service changes, and the terminal determines the first QoS flow and / or the first DRB corresponding to the uplink service after the service requirement changes, that is, the terminal determines the new QoS flow and / or the new DRB that adapt to the changed service requirement in real time when the service requirement changes.

[0163] Step S303, using the first QoS flow and / or the first DRB, sending data of the uplink service to the access network device;

[0164] In some embodiments, after the service requirement changes and the terminal determines the first QoS flow and / or the first DRB, the terminal can perform transmission of the uplink service based on the first QoS flow and / or the first DRB.

[0165] It should be noted that the embodiments of the present disclosure determine the first QoS flow and / or the first DRB corresponding to the uplink service by determining that the service requirement of the uplink service changes, and send data of the uplink service to the access network device using the first QoS flow and / or the first DRB, so as to timely adjust the QoS flow and / or the DRB when the service requirement changes, realize dynamic QoS adjustment based on the service requirement, and avoid the delay of the wireless transmission network to the service requirement change.

[0167] receiving a mapping rule of SDF to QoS flow sent by the core network device;

[0168] In some embodiments, the mapping rule is used to indicate the mapping relationship of SDF to QoS flow, for example, the mapping rule can be included in the uplink PDR, and the terminal can determine the association relationship of SDF to QoS flow according to the mapping rule.

[0170] determining, according to the mapping rule, the first QoS flow corresponding to the SDF associated with the service requirement of the uplink service.

[0171] It should be noted that different service requirements correspond to different QoS attributes, different QoS attributes correspond to different QoS flows, and the terminal can determine the QoS flow corresponding to the changed service requirement after determining the QoS attribute corresponding to the changed service requirement.

[0172] In some embodiments, in one implementation, before determining the first quality of service, QoS, flow and / or the first data radio bearer, DRB, corresponding to the uplink service, the method further comprises:

Specifically, different uplink DRB configuration parameters can meet different QoS requirements, and in the embodiments of the present disclosure, one or more sets of uplink DRB configuration parameters are configured for the terminal, so as to meet different QoS requirements.

[0179] In some embodiments, the uplink DRB configuration parameters include but are not limited to one or more of the following: priority, PBR, allowed sub-carrier spacing (SCS), maximum physical uplink shared channel (PUSCH) length, available preconfigured resources, and available carrier.

[0181] It should be noted that the mapping relationship generally refers to the association relationship between QFI and DRB identification information (such as DRB ID); by notifying the terminal of the mapping relationship between the uplink QoS flow and the DRB, the terminal can determine the changed DRB based on the changed uplink QoS flow.

[0182] In some embodiments, the specific implementation of determining the first data radio bearer, DRB, corresponding to the uplink service comprises:

[0183] determine, according to the configuration information, a first DRB associated with the service requirement of the uplink service.

[0184] It should be noted that different service requirements are associated with different DRBs, and the terminal can determine the first DRB associated with the changed service requirement after determining the changed service requirement. In some embodiments, the implementation process includes: different QoS attributes correspond to different QoS flows, and the terminal can determine the QoS flow corresponding to the changed service requirement after determining the QoS attribute corresponding to the changed service requirement. The terminal can determine the DRB associated with the changed service requirement based on the QoS flow corresponding to the changed service requirement.

[0185] In some embodiments, the specific implementation of determining, according to the configuration information, a first DRB associated with the service requirement of the uplink service includes:

[0186] If the mapping relationship between the first QoS flow corresponding to the SDF associated with the service requirement of the uplink service and the DRB is not included in the configuration information, a default DRB is determined as the first DRB associated with the service requirement of the uplink service.

[0187] It should be noted that this case can be understood as that the access network device does not configure the mapping relationship between the first QoS flow corresponding to the SDF associated with the changed service requirement and the DRB. In order to ensure that the terminal can normally transmit the uplink service after the service requirement changes, the terminal determines the default DRB as the DRB associated with the changed service requirement. In some embodiments, the default DRB can be a protocol agreement or a configuration on the access network device side.

[0188] In some embodiments, in an implementation, the specific implementation of transmitting, by using the first QoS flow and / or the first DRB, data of the uplink service to the access network device includes:

[0189] transmitting a user plane data unit of the uplink service on a transmission channel and / or a logical channel corresponding to the first DRB;

[0190] In some embodiments, the user plane data unit may, for example, be an uplink SDAP data PDU.

[0191] The user plane data unit includes at least one of B11 to B13:

[0192] B11, a QFI corresponding to the first QoS flow;

[0193] It should be noted that by notifying the access network device of the QFI, the access network device can be explicitly aware of which QoS flow the transmitted service data is for.

[0194] B12, third indication information, the third indication information is used for indicating that the mapping of the QoS flow to the DRB is changed;

[0195] In some embodiments, in the case where the configuration information described above includes the first indication information, in the case where the mapping of the QoS flow to the DRB is changed due to the change of the service requirement, the third indication information can be included in the user plane data unit; in some embodiments, if the configuration information described above includes the second indication information, the third indication information can be RDI.

[0196] In some embodiments, in one implementation, if the RDI field is configured in the user plane data unit and indicated by 1 bit, if the mapping of the QoS flow to the DRB is changed, the value of the RDI field is 1, and if the mapping of the QoS flow to the DRB is not changed, the value of the RDI field is 0; or, if the RDI field is configured in the user plane data unit and indicated by 1 bit, if the mapping of the QoS flow to the DRB is changed, the value of the RDI field is 0, and if the mapping of the QoS flow to the DRB is not changed, the value of the RDI field is 1.

[0197] B13, fourth indication information, the fourth indication information is used for indicating that the mapping of the SDF to the QoS flow is changed;

[0198] In some embodiments, in the case where the configuration information described above includes the first indication information, in the case where the mapping of the SDF to the QoS flow is changed due to the change of the service requirement, the fourth indication information can be included in the user plane data unit; in some embodiments, if the configuration information described above includes the second indication information, the fourth indication information can be RQI.

[0199] In some embodiments, in one implementation, if the RQI field is configured in the user plane data unit and indicated by 1 bit, if the mapping of the SDF to the QoS flow is changed, the value of the RQI field is 1, and if the mapping of the SDF to the QoS flow is not changed, the value of the RQI field is 0; or, if the RQI field is configured in the user plane data unit and indicated by 1 bit, if the mapping of the SDF to the QoS flow is changed, the value of the RQI field is 0, and if the mapping of the SDF to the QoS flow is not changed, the value of the RQI field is 1.

[0200] In some embodiments, the format of the uplink service user plane data unit in the embodiments of the present disclosure can be represented by one of C11 to C13:

[0201] C11. As shown in FIG. 4, the user plane data unit includes an RDI field, an RQI field, a QFI field, and a data field.

[0202] C12. As shown in FIG. 5, the user plane data unit includes a D / C field, an RDI field, a QFI field, and a data field.

[0203] C13. As shown in FIG. 6, the user plane data unit includes a D / C field, an RDI field, an RQI field, a QFI field, a data field, and a reserved field (represented by an R bit in FIG. 6).

[0204] In FIGS. 4-6, when the RDI field has a bit value of 1, it indicates that the mapping of a QoS flow to a DRB is changed; when the RQI field has a bit value of 1, it indicates that the mapping of an SDF to a QoS flow is changed; the QFI field indicates a QFI corresponding to a first QoS flow; and the D / C field identifies whether the current user plane data unit is a control PDU or a data PDU.

[0205] In some embodiments, after the access network device receives the user plane data unit sent by the terminal, if the QFI transmitted in the user plane data unit is not mapped to the first DRB, the access network device associates the first QoS flow corresponding to the QFI transmitted in the user plane data unit with the first DRB.

[0206] It should be noted that in this case, after the service requirement changes, the DRB used by the terminal for uplink service transmission does not change, and the previous DRB is still used, but the QFI carried in the user plane data unit changes at this time. After the access network device receives the user plane data unit, it is determined that the QFI carried in the user plane data unit is not mapped to the DRB used for uplink service transmission. At this time, the access network device needs to associate the first QoS flow corresponding to the QFI transmitted in the user plane data unit with the first DRB for transmitting uplink service.

[0207] In some embodiments, when the access network device includes fourth indication information in the user plane data unit, the access network device sends the fourth indication information to the core network device to notify the core network device that the mapping of an SDF to a QoS flow is changed, so that the core network device also timely adjusts the mapping of the SDF to the QoS flow.

[0208] In some embodiments, after the access network device receives the user plane data unit sent by the terminal, if it is determined that the user plane data unit is transmitted on a default DRB, a corresponding first DRB is configured for the first QoS flow corresponding to the QFI indicated in the user plane data unit.

[0209] It should be noted that in this case, if the access network device receives data of the uplink service transmitted using the default DRB, it can be determined that the mapping relationship between the first QoS flow carried in the user plane data unit and the DRB has not been configured before, and the access network device needs to configure the mapping relationship between the first QoS flow and the DRB.

[0210] In some embodiments, in one way, the access network device can directly configure the corresponding first DRB for the first QoS flow when the QoS parameter of the first QoS flow is stored at the access network device side.

[0211] In some embodiments, in another way, when the QoS parameter of the first QoS flow is not stored at the access network device side, in one implementation, the access network device configures the corresponding first DRB for the first QoS flow corresponding to the QFI indicated in the user plane data unit, including: the access network device sends QoS flow change indication information to the core network device, and receives the QoS requirement of the QoS flow corresponding to the QFI sent by the core network device; according to the QoS requirement, the first DRB corresponding to the first QoS flow corresponding to the QFI indicated in the user plane data unit is configured. In this case, it can be understood that if the QoS parameter of the first QoS flow is not stored at the access network device side, the access network device needs to first request the QoS requirement of the changed QoS flow from the core network device, and then configure the first DRB corresponding to the first QoS flow based on the QoS requirement.

[0212] In some embodiments, after the access network device configures the first DRB corresponding to the first QoS flow, the access network device can send the configuration of the first DRB and the mapping relationship between the first QoS flow corresponding to the QFI and the first DRB to the terminal. Specifically, it can be configured by using an explicit configuration parameter or by using a downlink reflective QoS.

[0213] In some embodiments, in one implementation, after the first QoS flow and / or the first DRB are used to send the uplink service data to the access network device, the method further includes at least one of the following:

[0214] D11, receiving the bearer configuration information of the uplink QoS flow to DRB mapping change sent by the access network device;

[0215] In this case, after the terminal performs DRB change of the uplink service, the access network device will also perform uplink and / or downlink bearer configuration based on the DRB change, and send the uplink and / or downlink bearer configuration information to the terminal after the configuration.

[0216] D12, receive the SDF to QoS flow mapping relationship and the QoS parameter after the SDF to QoS flow mapping of the core network device is changed;

[0217] This case can be understood as follows: after the terminal changes the QoS flow of the uplink service, the core network device will also configure the uplink and / or downlink SDF to QoS flow mapping based on the QoS flow change, and send the uplink and / or downlink SDF to QoS flow mapping relationship and the corresponding QoS parameter to the terminal after the configuration.

[0218] In some embodiments, the core network device in the embodiments of the present disclosure can be a network element for session management, for example, the core network device can be an SMF.

[0219] It should be noted that the embodiments of the present disclosure are applicable to any uplink service that needs to be dynamically adjusted, and in some embodiments, the uplink service can be an immersive service, for example, an XR service.

[0220] The specific application of the embodiments of the present disclosure will be illustrated below by taking the base station and the terminal performing XR service communication as an example.

[0221] Case 1: The terminal remaps the XR service to the configured QoS flow and DRB

[0222] Specifically, the main implementation process on the base station side includes:

[0223] Step S101, receive the configuration sent by the core network device for the terminal to change the uplink service mapping;

[0224] In some embodiments, the configuration can include one or more of the following: the identifier of the terminal that can perform uplink service mapping change; SDF number that can perform mapping change; QFI that can perform mapping change; QoS parameter (such as data rate, latency requirement, etc.) that can trigger mapping change; service characteristic parameter (such as packet size, period, latency jitter, etc.) that can trigger mapping change.

[0225] Step S102, send the configuration information to the terminal;

[0226] The configuration information includes one or more of the following:

[0227] First indication information, the first indication information is used to indicate whether to allow QoS flow mapping change and / or whether to allow uplink QoS change;

[0228] Second indication information, the second indication information is used to indicate whether to support reflective QoS based on uplink transmission;

[0229] At least one set of uplink DRB configuration parameters;

[0230] Mapping relationship between uplink QoS flow and DRB.

[0231] In step S103, the base station receives the data of the uplink service sent by the terminal, and parses the user plane data unit, such as SDAP data PDU. If the uplink QoS flow is remapped, in some embodiments, the bit value of the RDI field in the user plane data unit is 1 and / or the bit value of the RQI field is 1.

[0232] In step S104, the base station adopts one of the following operations according to the received user plane data unit:

[0233] If the QFI carried by the user plane data unit is originally mapped to the DRB that carries the data, the bit value of the RDI field is 0, and the bit value of the RQI field is 1. The base station can also report the RQI to the core network device, and the core network device updates the mapping of the uplink service data flow to the QoS flow, and in some embodiments, updates the mapping of the corresponding downlink service data flow to the QoS flow.

[0234] If the QFI corresponding to the QoS flow carried by the user plane data unit is originally not mapped to the DRB that carries the data, the bit value of the RDI field is 1. The base station maps the uplink QoS flow corresponding to the QFI to the DRB, and in some embodiments, updates the mapping of the downlink QFI and the downlink DRB (i.e., maps the downlink QoS flow corresponding to the QFI to the downlink DRB corresponding to the downlink DRB ID). If the bit value of the RQI field is 1, the base station reports the RQI to the core network device, and the core network device updates the mapping of the uplink service data flow to the QoS flow, and in some embodiments, updates the mapping of the corresponding downlink service data flow to the QoS flow.

[0235] Specifically, the main implementation process on the terminal side includes:

[0236] In step S111, the terminal receives the mapping rule of SDF to QoS flow sent by the core network device.

[0237] The terminal can determine the association relationship between SDF and QoS flow according to the mapping rule.

[0238] In step S112, the terminal receives the configuration information sent by the base station.

[0239] Step S113, the terminal judges whether the QoS requirement of the uplink service changes, if the QoS requirement changes, selects a QoS flow that can meet the current QoS requirement, and / or a DRB configuration that can meet the current QoS requirement. The user plane data unit is transmitted on the transport channel and / or logical channel corresponding to the selected DRB, the user plane data unit carries the QFI of the selected QoS flow, the bit value of the RDI field in the user plane data unit is 1, which is used to indicate that the mapping of the QoS flow to the DRB changes, and the bit value of the RQI field is 1, which is used to indicate that the mapping of the service data flow (IP flow or Ethernet flow) to the QoS flow changes.

[0240] Step S114, the receiving base station receives the bearer configuration information after the uplink QoS flow to DRB mapping changes, and / or receives the SDF to QoS flow mapping relationship and new QoS parameters after the SDF to QoS flow mapping changes sent by the core network device through the NAS message.

[0241] It should be noted that this step 114 is an optional step.

[0242] Case two, the terminal remaps the XR service to the configured DRB and newly associates the QFI and the DRB

[0243] Specifically, the main implementation process on the base station side includes:

[0244] Step S201, receiving the configuration sent by the core network device for the terminal to change the uplink service mapping rule;

[0245] Step S202, sending the configuration information to the terminal;

[0246] The configuration information includes one or more of the following:

[0247] The first indication information is used to indicate whether the QoS flow mapping change is allowed and / or whether the uplink QoS change is allowed;

[0248] The second indication information is used to indicate whether the reflective QoS based on the uplink transmission is supported;

[0249] At least one set of uplink DRB configuration parameters;

[0250] The mapping relationship between the uplink QoS flow and the DRB.

[0251] Step S203, receiving the data of the uplink service sent by the terminal, parsing the user plane data unit, such as SDAP data PDU. If the uplink QoS flow is remapped, in some embodiments, the bit value of the RDI field in the user plane data unit is 1 and / or the bit value of the RQI field is 1.

[0252] Step S204, if the QFI does not appear in the previously stored QoS flow and DRB mapping relationship, mapping the QoS flow corresponding to the QFI to the DRB carrying the user plane data unit, and applying the parameters configured for the DRB. In some embodiments, the downlink QoS flow of the QFI is mapped to the downlink DRB of the DRB ID. If the bit value of the RQI field is 1, the base station reports the RQI to the core network device, and the core network device updates the mapping of the uplink service flow to the QoS flow, and in some embodiments, updates the mapping of the corresponding downlink service data flow to the QoS flow.

[0253] Specifically, the main implementation process on the terminal side includes:

[0254] Step S211, receiving the mapping rule of SDF to QoS flow sent by the core network device;

[0255] The terminal can determine the association relationship of SDF to QoS flow according to the mapping rule.

[0256] Step S212, receiving the configuration information sent by the base station;

[0257] Step S213, the terminal judges whether the QoS requirement of the uplink service changes, if it changes, selects the QoS flow that can meet the current QoS requirement, and / or the DRB configuration that can meet the current QoS requirement. Organize the user plane data unit to be transmitted on the transmission channel and / or logical channel corresponding to the selected DRB, the user plane data unit carries the QFI of the selected QoS flow, the bit value of the RDI field carried in the user plane data unit is 1, which is used to indicate the mapping change of QoS flow to DRB, and the bit value of the RQI field is 1, which is used to indicate the mapping change of service data flow (IP flow or Ethernet flow) to QoS flow.

[0258] Step S214, receiving the bearer configuration information of the base station after the uplink QoS flow to DRB mapping change, and / or receiving the mapping relationship of SDF to QoS flow and the new QoS parameter of SDF to QoS flow after the mapping change of SDF to QoS flow sent by the core network device through the NAS message;

[0259] It should be noted that this step S214 is an optional step.

[0260] Case three, the current configured DRB of the terminal cannot meet the new QoS requirement of the service flow

[0261] Specifically, the main implementation process of the base station side includes:

[0262] Step S301, receiving the configuration of the core network device for the terminal to change the uplink service mapping rule;

[0263] Step S302, sending the configuration information to the terminal;

[0264] The configuration information includes one or more of the following:

[0265] The first indication information is used to indicate whether to allow QoS flow mapping change and / or whether to allow uplink QoS change;

[0266] The second indication information is used to indicate whether to support reflective QoS based on uplink transmission;

[0267] At least one set of uplink DRB configuration parameters;

[0268] The mapping relationship between the uplink QoS flow and the DRB.

[0269] Step S303, receiving the data of the uplink service sent by the terminal, parsing the user plane data unit such as SDAP data PDU. If the uplink QoS flow is remapped, in some embodiments, the bit value of the RDI field in the user plane data unit is 1 and / or the bit value of the RQI field is 1. Since the terminal cannot find a DRB that can meet the QoS requirement, the user plane data unit is mapped to the default DRB for transmission.

[0270] Step S304, the base station detects that the user plane data unit with a new QFI is transmitted on the default DRB, and adopts one of the following ways:

[0271] Send the QoS flow change indication information to the core network device, obtain the QoS requirement of the QoS flow corresponding to the QFI, configure the corresponding DRB for the QoS flow, and send the new DRB configuration and the mapping relationship between the new QFI and the new DRB ID to the terminal (using explicit configuration parameters or using downlink reflective QoS);

[0272] If the base station stores the QoS parameter of the QoS flow corresponding to the QFI, configure the corresponding DRB for the QoS flow, and send the new DRB configuration and the mapping relationship between the new QFI and the new DRB ID to the terminal (using explicit configuration parameters or using downlink reflective QoS).

[0273] Specifically, the main implementation process on the terminal side includes:

[0274] Step S311, receiving the mapping rule of SDF to QoS flow sent by the core network.

[0275] The terminal can determine the association relationship of SDF to QoS flow according to the mapping rule.

[0276] Step S312, receiving the configuration information sent by the base station.

[0277] Step S313, the terminal judges whether the QoS requirement of the uplink service changes, if the change occurs, selects the QoS flow that can meet the current QoS requirement, and / or the DRB configuration that can meet the current QoS requirement. If no DRB configuration that meets the current QoS requirement is found, the QoS flow corresponding to the new QFI is mapped to the default DRB. The user plane data unit is transmitted on the transport channel and / or logical channel corresponding to the default DRB, the user plane data unit carries the QFI of the selected QoS flow, the bit value of the RDI field carried in the user plane data unit is 1, which is used to indicate the mapping change of QoS flow to DRB, and the bit value of the RQI field is 1, which is used to indicate the mapping change of service data flow (IP flow or Ethernet flow) to QoS flow.

[0278] Step S314, receiving the new DRB configuration of the QoS flow corresponding to the new QFI on the base station side, and mapping the QoS flow corresponding to the new QFI to the new DRB.

[0279] It should be noted that at least one embodiment of the present disclosure can realize dynamic QoS adjustment of uplink service that needs to be dynamically adjusted according to service requirements, quickly adjust the mapping relationship of service flow to QoS flow and the mapping relationship of QoS flow to DRB, and configure the air interface transmission parameters that can meet the QoS requirement of service data.
