Description
Transmission control method and device, terminal and access network equipment
[0001] The present disclosure claims priority to the Chinese patent application No. 202411291700.0, filed on September 14, 2024, entitled "Transmission control method and device, terminal and access network equipment", and the Chinese patent application No. 202511185886.6, filed on August 22, 2025, entitled "Transmission control method and device, terminal and access network equipment", the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0003] Immersive communication represented by extended reality (XR) is an important service requirement of the sixth generation (6G). The traffic pattern of XR service changes dynamically based on the use scenario and application. For example, the media frame size can change rapidly due to the initial start of the service or the user dragging the service process. The service characteristics can change significantly in the file download of the Artificial Intelligence (AI) model update.
[0004] The current Quality of Service (QoS) configuration and notification mechanism of the fifth generation (5G) cannot meet the dynamic change requirements 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 delay in the change of service requirements of the wireless transmission network and affecting the performance of the service.

[0155] With reference to the drawings, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of the present disclosure.
[0156] The terms "first", "second", and the like in the description and claims of the present disclosure are used to distinguish similar objects, and do not necessarily indicate a specific order or 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 that includes a list of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to such processes, methods, products, or devices.
[0157] 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 represent the following three cases: 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 "multiple" means two or more, and other quantifiers are similar.
[0158] 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 advantageous than other embodiments or design solutions. Rather, the use of the words "exemplary" or "for example" is intended to present the relevant concept in a specific manner.
[0159] The related concepts mentioned in the present disclosure will be briefly described as follows.
[0160] In the 5G system, the core network performs mapping of service data flow (SDF) (such as Internet Protocol (IP) flow or Ethernet flow) to Quality of Service (QoS) flow, and the access network performs mapping of QoS flow to Data Radio Bearer (DRB).
[0161] The mapping of SDF to QoS flow is controlled by the core network element. In the downlink direction, the User Plane Function (UPF) of the core network performs the mapping of SDF to QoS flow, and the mapping rule is sent to the UPF by the Session Management Function (SMF); in the uplink direction, the mapping of SDF to QoS flow is performed by the terminal, and the mapping rule is sent to the terminal by the core network through a Non-Access-Stratum (NAS) message. A QoS flow is associated with a Quality of Service profile (QoS profile), a Quality of Service rule (QoS Rule), and a Packet Detection Rule (PDR). The PDR has a downlink PDR and an uplink PDR, and contains a series of parameters such as a source interface, a UE IP address, an IP multimedia address, an SDF filter, and a QoS Flow identifier (QFI), to achieve the mapping of a traffic flow to a QoS flow. FIG. 1 is a schematic diagram of the classification and mapping of SDF to QoS flow.
[0162] The SMF of the core network sends a QoS Profile of each QoS flow to the base station. The QoS profile corresponds to the QoS parameters of the QoS flow. The QoS parameters include: a 5G QoS Identifier (5QI), which corresponds to specific parameters such as a Packet Delay Budget (PDB) and a Packet Error Rate (PER); an Allocation and Retention Priority (ARP); a Guaranteed Flow Bit Rate (GFBR) and a Maximum Flow Bit Rate (MFBR) for a Granted Bit Rate (GBR) QoS Flow; a Reflective QoS Attribute (RQA) for a Non-GBR (NGBR) QoS Flow, etc. Each QoS profile has a corresponding QFI, which is used to identify a QoS flow.
[0163] 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, 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.
[0164] The 5G QoS mechanism cannot adapt to the dynamically changing requirements of immersive services, especially uplink services. The 5G QoS mechanism cannot timely respond to changes in services, which will cause a delay in the change of service requirements of the wireless transmission network, resulting in an impact on service performance.
[0165] Embodiments of the present disclosure are described below with reference to the accompanying drawings. The transmission control method and device, 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). Those skilled in the art can understand that the 5G NR system is only an example and is not limited.
[0166] Referring to FIG. 2, FIG. 2 is a structure 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, etc. 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.
[0167] The embodiments of the present disclosure provide a transmission control method and device, a terminal and an 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.
[0168] The method and the device are based on the same application concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.
[0169] As shown in FIG. 3, the embodiments of the present disclosure provide a transmission control method, which is executed by a terminal and includes the following steps.
[0170] In step S301, configuration information sent by an access network device is received, and the configuration information is used to configure at least two sets of transmission parameters of a QoS flow and / or a DRB.
[0171] It should be noted that the transmission parameters can be used to guarantee the QoS requirement of uplink transmission.
[0172] In some embodiments, the QoS requirement refers to the service transmission characteristics, which can be understood as a QoS attribute, and can also be referred to as a service requirement. For example, the QoS requirement can be the value requirement of PDB, PER and the like, that is, different QoS requirements correspond to different parameter values.
[0173] In step S302, according to the configuration information, transmission parameters of the QoS requirement are selected for uplink transmission.
[0174] In some embodiments, the at least two sets of transmission parameters of the QoS flow and / or the DRB are at least two sets of transmission parameters of a QoS flow and / or a DRB corresponding to a target service data flow SDF.
[0175] The step of selecting, according to the configuration information, transmission parameters of the QoS requirement for uplink transmission includes the following steps.
[0176] According to the configuration information, transmission parameters satisfying the QoS requirement of the target SDF are selected for uplink transmission.
[0177] The QoS flow can also correspond to an AI flow or a data flow. Different QoS flows correspond to AI flows or data flows with different service quality requirements.
[0178] It should be noted that by receiving the configuration information sent by the access network device for configuring at least two sets of transmission parameters of the QoS flow and / or DRB corresponding to the target SDF, and selecting the transmission parameters meeting the QoS requirement of the target SDF for uplink transmission according to the configuration information, the appropriate transmission parameters can be used in time according to the QoS requirement, and the delay of the wireless transmission network to the service requirement change is avoided.
[0179] In some embodiments, in an implementation, the configuration information includes the following one of A11 and A12:
[0180] A11, at least two DRBs mapped to the QoS flow, the DRB containing the transmission parameters of the QoS requirement of the target SDF;
[0181] In this case, it means that one QoS flow corresponds to at least two DRBs, that is, the configuration information includes at least two DRBs mapped to one QoS flow.
[0182] In some embodiments, the QoS requirement of the target SDF and the DRB can be at least one of many-to-many, many-to-one, one-to-many, and one-to-one; preferably, the QoS requirement of the target SDF and the DRB is one-to-one, that is, this case can be understood as that each DRB contains a set of transmission parameters of one type of QoS requirement of the target SDF;
[0183] In some embodiments, this case can be understood as that one QoS flow can be mapped to two or more DRBs, each DRB is configured with different transmission parameters to adapt to different QoS requirements, such as DRB1 is suitable for large data volume transmission, and DRB2 is suitable for small data volume transmission.
[0184] In some embodiments, in this case, when the service transmission characteristic changes, the terminal maps the current QoS flow (that is, the QoS flow and the corresponding QFI do not change) to the DRB that can meet the QoS requirement.
[0185] In some embodiments, in an implementation, a set of transmission parameters includes at least one of the following:
[0186] A21, priority of a logical channel;
[0187] A22, Prioritized Bit Rate (PBR);
[0188] A23, Bucket Size Duration (BSD);
[0189] A24, a sub-carrier space (SCS) allowed to be used;
[0190] A25, a maximum physical uplink shared channel (PUSCH) length;
[0191] A26, a pre-configured resource allowed to be used;
[0192] A27, a carrier allowed to be used.
[0193] In some embodiments, the specific parameters contained in the transmission parameters corresponding to different DRBs can be the same or different, and in addition, at least part of the parameters in different sets of transmission parameters are different in value in the case that the parameters contained in different DRBs are the same.
[0194] A12, at least two sets of transmission parameters corresponding to the DRB, the transmission parameters corresponding to the QoS requirement of the target SDF;
[0195] In this case, one DRB corresponds to at least two sets of transmission parameters, that is, the configuration information includes at least two sets of transmission parameters corresponding to one DRB.
[0196] In some embodiments, the transmission parameters and the QoS requirement of the target SDF can be at least one of a many-to-many, many-to-one, one-to-many, and one-to-one relationship; preferably, the transmission parameters and the QoS requirement of the target SDF are in a one-to-one relationship, that is, this case can be understood as one set of transmission parameters corresponding to one type of QoS requirement of the target SDF.
[0197] In some embodiments, this case can be understood as one DRB being configured with multiple sets of transmission parameters, which can also be referred to as multiple sets of transmission parameter sets in some embodiments, for example, one DRB is configured with more than one PBR, for example, the value of PBR1 is greater than the value of PBR2, which are respectively used for QoS requirements of large data transmission and small data transmission.
[0198] In some embodiments, in this case, the terminal changes the transmission parameters used when the service transmission characteristics change, so that the QoS requirement can be met.
[0199] In some embodiments, in one implementation, the method further includes:
[0200] sending first indication information to the access network device, the first indication information being used to indicate at least one of:
[0201] B11, a change of QoS flow to DRB mapping;
[0202] In some embodiments, the indication manner is generally applicable to the configuration manner of A11 described above.
[0203] B12, a transmission parameter used by the terminal;
[0204] In some embodiments, the transmission parameter used by the terminal can be indicated by the number of the transmission parameter or the number of the set of transmission parameters.
[0205] B13, a transmission parameter used by the terminal changes;
[0206] It should be noted that the indication manners of B12 and B13 described above are applicable to the configuration manner of A12 described above.
[0207] In some embodiments, in one implementation, the specific implementation of sending the first indication information to the access network device includes at least one of the following:
[0208] C11, sending Radio Resource Control (RRC) signaling to the access network device, wherein the RRC signaling includes the first indication information;
[0209] C12, sending a user plane control unit to the access network device, wherein the user plane control unit carries the first indication information;
[0210] In some embodiments, the user plane control unit may, for example, be an SDAP control Protocol Data Unit (PDU) or a Packet Data Convergence Protocol (PDCP) control PDU.
[0211] For example, for the case of B11, the user plane control unit includes a QoS flow to DRB mapping change indication field, which is used to carry the first indication information; it should be noted that the scenario in which the access network device needs to know that the terminal has made QoS flow to DRB remapping is that the access network device needs to notify the core network device of QoS flow mapping change, so that the core network device determines that the filter or flow template needs to be changed; further, if the reflective QoS mechanism needs to be adopted, the downlink QoS flow to DRB mapping needs to be adjusted accordingly. If the terminal does not notify the access network device of the change of QoS flow to DRB mapping, the access network device does not need to notify the core network device of the QoS flow mapping change by default.
[0212] For example, for the case of B12 or B13, the user plane control unit includes a transmission parameter change indication field, which is used to carry the first indication information.
[0213] C13, perform uplink transmission by the changed transmission parameter, wherein the changed transmission parameter is used for implicitly indicating the first indication information;
[0214] It should be noted that this case belongs to the implicit indication of the first indication information, and in some embodiments, the setting of the default transmission parameter is generally required in this case, for example, the default DRB for QoS flow mapping is set, and if the access network device determines that the terminal does not use the default DRB according to the received uplink transmission, it can be determined that the QoS flow to DRB mapping of the terminal has changed; for example, the default transmission parameter of the DRB is set to transmission parameter set 1, and if the access network device determines that the terminal does not use the default transmission parameter according to the received uplink transmission, it can be determined that the transmission parameter has changed or the QoS flow to DRB mapping has changed.
[0215] In some embodiments, in an implementation, the method further comprises:
[0216] In the case where the transmission parameter used by the terminal changes, the first timer is started;
[0217] After the first timer expires, the QoS flow is mapped to the first DRB or the uplink data is transmitted using the first set of transmission parameters corresponding to the DRB;
[0218] The transmission parameter corresponding to the first DRB is the transmission parameter before the change or the default DRB; the first set of transmission parameters is the transmission parameter before the change or the default DRB transmission parameter.
[0219] In some embodiments, the default DRB can be agreed by the protocol or configured by the access network device, and the default DRB transmission parameter can be agreed by the protocol or configured by the access network device.
[0220] It should be noted that this mode can be understood as the setting of the effective duration of the transmission parameter change, and the terminal side sets the first timer (the timing duration of the first timer is the effective duration of the transmission parameter change), during the running of the first timer, the terminal always uses the changed transmission parameter for uplink transmission, and after the first timer expires, the terminal performs the fallback of the QoS flow mapping or the fallback of the transmission parameter corresponding to the DRB, so as to avoid the problem of large resource overhead caused by the terminal always using the changed transmission parameter for uplink transmission by setting the effective duration of the transmission parameter change.
[0221] In some embodiments, in cooperation with the terminal side implementation, the access network device starts a second timer in the case of determining that the terminal changes the transmission parameter; after the second timer expires, it is determined that the QoS flow is mapped to the first DRB or the uplink data is received using the first set of transmission parameters corresponding to the DRB.
[0222] The transmission parameter corresponding to the first DRB is the transmission parameter before the change or the default DRB; and the first set of transmission parameters is the transmission parameter before the change or the default DRB transmission parameter.
[0223] It should be noted that the terminal and the access network device side understand the use of the transmission parameter is consistent, so if the terminal uses the first timer, the access network device can also use the second timer to determine whether the transmission parameter is rolled back.
[0224] In some embodiments, the timing duration of the second timer is the same as the timing duration of the first timer.
[0225] In some embodiments, whether the access network device sends the configuration information can be determined by the core network device, and the specific implementation manner includes: the access network device receives second indication information sent by the core network device, the second indication information is used to indicate that the target QoS flow corresponding to the target SDF can change the uplink service requirement or different service requirements of the target SDF correspond to different QoS parameters; according to the second indication information, the configuration information is sent to the terminal.
[0226] In some embodiments, in one implementation manner, the method further includes:
[0227] Receiving the mapping rule of SDF to QoS flow sent by the core network device, the mapping rule is used to indicate that multiple QoS requirements of the target SDF correspond to one QoS flow.
[0228] It should be noted that through the configuration of the mapping rule, one SDF can still be mapped to one QoS flow (i.e., mapped to one QFI) when the QoS attribute changes, for example, two flow mapping templates are configured for one SDF, and both of the two flow mapping templates map SDF1 to QFI1.
[0229] 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.
[0230] It should be noted that the embodiments of the present disclosure are applicable to any uplink service whose service requirement needs to be dynamically adjusted, and in some embodiments, the uplink service can be an immersive service, for example, an XR service.
[0231] The following takes the base station and terminal communication as an example to illustrate the specific application of the embodiments of the present disclosure as follows.
[0232] Application Case One: QoS flow to DRB mapping relationship change
[0233] Specifically, the base station side mainly includes the following processes:
[0234] Step S101, send configuration information to the terminal, the configuration information indicates that for the QoS flow (QFI1) corresponding to the target SDF, one QoS flow can be mapped to more than one DRB. For example, the QoS flow of QFI=1 can be mapped to DRB1 and DRB2 of DRB ID=1 and DRB ID=2. The two DRBs are respectively configured with different transmission parameters for meeting different QoS requirements, such as DRB1 can meet small data transmission and DRB2 can meet large data transmission. The transmission parameters of the DRB include but are not limited to one or more of the following: the priority of the logical channel corresponding to the DRB, PBR, BSD, allowed SCS, maximum PUSCH length, available preconfigured resources, and available carriers. In some embodiments, a default DRB is configured, such as DRB1. In some embodiments, a QoS to DRB mapping change duration T1 is configured.
[0235] Step 102, the base station determines that the terminal has changed the QoS flow to DRB mapping in one of the following ways:
[0236] RRC explicit indication: receive the RRC signaling sent by the terminal, and the RRC signaling includes first indication information, the first indication information is used to indicate the change of QoS flow to DRB mapping, such as that QFI1 is mapped to DRB1 is changed to QFI1 is mapped to DRB2;
[0237] User plane explicit indication: receive the uplink transmission on DRB1 or DRB2, and in the user plane control unit (SDAP control PDU or PDCP control PDU), analyze the QoS flow to DRB mapping change field, which is used to indicate that the QoS flow to DRB mapping has changed, or the DRB number to which QFI1 is mapped;
[0238] Implicit indication: DRB1 is the default DRB of QFI1, and the uplink transmission of QFI=1 is received on DRB2, then it is confirmed that the terminal has changed the QoS flow to DRB mapping.
[0239] Step S103, the base station schedules and allocates resources for the uplink transmission of the terminal based on the parameters of the changed DRB.
[0240] Step S104, start a second timer, and if the second timer expires, it is considered that the terminal reverts to the default mapping relationship, i.e., QFI1 is mapped to DRB1.
[0241] The timing duration of the second timer is the QoS-to-DRB mapping change duration T1.
[0242] It should be noted that this step S104 is an optional step.
[0243] Step S105, report the service requirement change of QFI1 of the terminal to the core network device.
[0244] It should be noted that this step S105 is an optional step.
[0245] Before that, the base station can also receive second indication information of the core network device to determine that the terminal can change the uplink service requirement for a specific QoS flow, such as QFI1, and / or the QoS parameters (GFBR, etc.) under different service requirements, thereby configuring more than one set of DRB transmission parameters for the terminal.
[0246] Specifically, the terminal side mainly includes the following processes:
[0247] Step S111, receive the configuration information sent by the base station, and determine that for the QoS flow (QFI1) corresponding to the target SDF, one QoS flow can be mapped to more than one DRB. For example, the QoS flow QFI=1 can be mapped to DRB1 and DRB2 with DRB ID=1 and DRB ID=2. The two DRBs have different transmission parameter configurations, such as DRB1 can satisfy small data volume transmission, and DRB2 can satisfy large data volume transmission. In some embodiments, a default DRB, such as DRB1, is configured. In some embodiments, the QoS-to-DRB mapping change duration T1 is configured.
[0248] Step S112, indicate the QoS flow-to-DRB mapping change to the base station in one of the following ways:
[0249] RRC explicit indication: send RRC signaling to the base station, and the RRC signaling includes first indication information, which is used to indicate the change of QoS flow-to-DRB mapping, such as the change of QFI1 mapping to DRB1 to QFI1 mapping to DRB2;
[0250] User plane explicit indication: sending uplink data transmission on DRB1 or DRB2, in the user plane control unit (SDAP control PDU or PDCP control PDU), containing the QoS flow to DRB mapping change field, which is used to indicate that the QoS flow to DRB mapping changes (1 bit change indication), or the DRB number (QFI and DRB ID) to which QFI1 is mapped;
[0251] Implicit indication: sending uplink transmission on the new DRB, the user plane control unit of the uplink transmission contains QFI. For example, DRB1 is the default DRB of QFI1, when the QoS flow to DRB mapping relationship changes, send uplink transmission containing QFI=1 indication field on DRB2.
[0252] Step S113, transmitting data of QFI=1 QoS flow on the changed DRB and the corresponding logical channel.
[0253] Step S114, starting a first timer, and when the first timer expires, considering that the terminal reverts to the default mapping relationship, i.e., QFI1 is mapped to DRB1. Or, when the service requirement of the terminal changes, the terminal re-performs the QoS flow to DRB mapping, and executes steps S112 and S113.
[0254] The timing duration of the first timer is the QoS to DRB mapping change duration T1.
[0255] It should be noted that this step S114 is an optional step.
[0256] Step S115, reporting the service requirement change of QFI1 of the terminal to the core network device through NAS signaling.
[0257] Before this, the terminal receives the SDF to QoS flow mapping rule sent by the core network device, and determines that the terminal has multiple sets of service data flow to QoS flow mapping templates for the target SDF and / or QoS flow, so that the QoS requirement of one SDF can be mapped to one QFI even if it changes.
[0258] It should be noted that this step S115 is an optional step.
[0259] Application case two, application of DRB transmission parameter (set) change
[0260] Specifically, the base station side mainly includes the following processes:
[0261] Step S201, send configuration information to the terminal, the configuration information is used for configuring more than one set of transmission parameters (or also can be called as transmission parameter set) for DRB1 to which the QoS flow with QFI=1 is mapped, such as setting transmission parameter set 1 and transmission parameter set 2, the PBR in transmission parameter set 1 is less than the PBR in transmission parameter set 2, and / or, transmission parameter set 1 can use preconfigured resource CG1, and transmission parameter set 2 can use preconfigured resource CG2. In some embodiments, a default transmission parameter set, such as transmission parameter set 1, is configured. In some embodiments, the validity duration T2 of transmission parameter set change is configured.
[0262] Step S202, the base station determines that the configuration parameter of DRB1 used by the terminal changes in one of the following ways:
[0263] RRC explicit indication: receiving RRC signaling sent by the terminal, the RRC signaling includes first indication information, the first indication information is used to indicate the transmission parameter used by the terminal, i.e. the transmission parameter in effect in DRB1.
[0264] User plane explicit indication: receiving uplink transmission of the terminal on DRB1 or DRB2, in the user plane control unit (such as SDAP control PDU or PDCP control PDU), analyzing the transmission parameter change indication field, which is used to indicate that the transmission parameter in effect in DRB1 changes (1 bit change indication), or the number of transmission parameter in effect.
[0265] Implicit indication: the terminal uses different transmission parameter from before to send uplink transmission. For example, preconfigured resource CG1 is contained in transmission parameter set 1, and preconfigured resource CG2 is contained in transmission parameter set 2, the terminal originally uses transmission parameter set 1 to send uplink transmission, when the service demand changes, uses CG2 to send uplink transmission, then the base station determines that the terminal changes the transmission parameter set to transmission parameter set 2.
[0266] Step S203, the base station schedules and allocates resources for uplink transmission of the terminal based on the changed transmission parameter.
[0267] Step S204, start a second timer, and when the second timer expires, it is considered that the terminal reverts to the default transmission parameter set, i.e. transmission parameter set 1 of DRB1.
[0268] The timing duration of the second timer is the validity duration T2 of transmission parameter set change.
[0269] It should be noted that this step S204 is an optional step.
[0270] Step S205, report the change of QoS demand of QFI1 of the terminal to the core network device.
[0271] It should be noted that the step S205 is an optional step.
[0272] Before that, the base station can also receive second indication information of the core network device, determine that the terminal can change the uplink service requirement for a specific QoS flow, such as the QoS flow corresponding to QFI1, and / or the QoS parameters (GFBR, etc.) under different service requirements, so as to configure more than one set of transmission parameters for the terminal.
[0273] Specifically, the terminal side mainly includes the following processes:
[0274] Step S211, receiving the configuration information sent by the base station, determining that there are more than one set of transmission parameter configurations for DRB1 to which the specific QoS flow (QFI1) is mapped, such as setting transmission parameter set 1 and transmission parameter set 2, the PBR in the transmission parameter set 1 is smaller than the PBR in the transmission parameter set 2, and / or the transmission parameter set 1 can use the preconfigured resource CG1, and the transmission parameter set 2 can use the preconfigured resource CG2. In some embodiments, a default transmission parameter set, such as transmission parameter set 1, is configured. In some embodiments, the validity duration T2 of the transmission parameter set change is configured.
[0275] Step S212, indicating the transmission parameter change of DRB1 to the base station in one of the following ways:
[0276] RRC explicit indication: sending RRC signaling to the base station, wherein the RRC signaling includes first indication information, and the first indication information is used to indicate the transmission parameter used by the terminal, i.e., the transmission parameter in effect in DRB1.
[0277] User plane explicit indication: sending uplink data transmission to the base station on DRB1 or DRB2, and in the user plane control unit (such as SDAP control PDU or PDCP control PDU), a transmission parameter change indication field is included, which is used to indicate that the transmission parameter in effect in DRB1 changes (1 bit change indication), or the number of transmission parameters in effect.
[0278] Implicit indication: using different transmission parameters from before to send uplink transmission. For example, the preconfigured resource CG1 is included in the transmission parameter set 1, and the preconfigured resource CG2 is included in the transmission parameter set 2, and the terminal originally uses the transmission parameter set 1 to send uplink transmission, and when the service requirement changes, uses CG2 to send uplink transmission.
[0279] Step S213, transmitting the data of the QoS flow with QFI=1 based on the changed transmission parameter.
[0280] Step S214, a first timer is started, and when the first timer expires, it is considered that the terminal reverts to the default transmission parameter set, i.e., the transmission parameter set 1 of the DRB1. Alternatively, when the service requirement changes, the terminal reselects the transmission parameter set of the DRB1, and steps S212 and S213 are performed.
[0281] The timing duration of the first timer is the effective duration T2 of the transmission parameter set change.
[0282] It should be noted that the step S214 is an optional step.
[0283] Step S215, the terminal reports the service requirement change of the QFI1 to the core network device through NAS signaling.
[0284] Before this, the terminal receives the mapping rule of the SDF to the QoS flow sent by the core network device, and determines that the terminal has multiple sets of mapping templates of the service data flow to the QoS flow for the target SDF and / or the QoS flow, so that in the case of the QoS requirement change of one service data flow, one QFI can be mapped.
[0285] It should be noted that the step S215 is an optional step.
[0286] It should be noted that at least one embodiment of the present disclosure can realize dynamic QoS adjustment for immersive services, quickly change and apply the air interface transmission parameters, avoid the delay of the wireless transmission network to the service requirement change, and realize real-time QoS guarantee.
