[0055] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0056] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0057] In the embodiments of the present application, the terms "first", "second", etc. are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0058] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] In order to facilitate a clearer understanding of the technical solutions of the embodiments of the present application, some technical contents related to the embodiments of the present application are first introduced.

[0060] Notification control is an optional QoS parameter. The Session Management Function (SMF) can decide whether to enable QoS Notification Control (QNC) for a QoS Flow based on the information in the Policy and Charging Control (PCC) Rule issued by the Policy Control Function (PCF). The Notification control parameter will be sent to the Radio Access Network (RAN) as part of the QoS Profile.

[0061] Figure 1 A flowchart of QNC processing performed by RAN provided for related technologies, such as Figure 1As shown, when the event of "Guaranteed Flow Bit Rate (GFBR) can no longer be guaranteed" or "GFBR can be guaranteed again" of a GBR QoS Flow occurs, the RAN will notify the SMF, and then the SMF forwards the notification to the PCF.

[0062] In addition, an Alternative QoS Profile can be provided for a GBR QoS flow with notification control enabled. If the corresponding PCC rule contains Alternative QoS related information, in addition to the QoS profile, the SMF shall also provide the RAN with a priority list of the Alternative QoS Profile.

[0063] When the RAN sends a notification to the SMF that a QoS profile is not met, if the currently met QoS value matches the Alternative QoS profile, the notification message to the SMF shall also include a reference to the Alternative QoS profile to indicate the QoS currently met by the RAN. In summary, the RAN shall enable the SMF to determine the Alternative QoS profile (by reference) corresponding to the QoS currently met by the RAN, or notify the SMF that the lowest priority Alternative QoS Profile cannot be met either.

[0064] The current notification control solution supports QoS Flow granularity, but does not provide notification control capability for QoS at the protocol data unit (PDU) set (Set) granularity.

[0065] To this end, the embodiments of the present application are based on the existing QoS parameter notification control method and extend support for QoS notification control functions with PDU Set as the granularity.

[0066] Figure 2 One of the flow diagrams of the QoS parameter notification control method provided in the embodiment of the present application is applied to access network equipment, such as Figure 2 As shown, the method comprises the following steps:

[0067] Step 200: Receive a QoS configuration file of one or more PDU Sets sent by the SMF, where the QoS configuration file includes QNC parameters of the PDU Set.

[0068] Step 201: Send first indication information to the SMF according to the QoS profile of one or more PDU Sets, where the first indication information is used to indicate QoS information of a first PDU Set in the one or more PDU Sets.

[0069] Specifically, in the QoS parameter notification control scenario, the access network device (such as RAN) can receive the QoS profile of one or more PDU Sets sent by the SMF. For example, if there are two PDU Sets that need QoS parameter notification control, the access network device can receive the QoS profiles of the two PDU Sets sent by the SMF.

[0070] A PDU Set consists of one or more PDUs and can carry the payload of information units generated at the application layer.

[0071] The QoS configuration file received by the access network device may include QNC parameters of one or more PDU Sets. For example, if there are two PDU Sets that require QoS parameter notification control, the QNC parameters of the two PDU Sets may be included in one QoS configuration file or in two QoS configuration files. The QNC parameters of the PDU Set may be parameters related to the QoS notification control of the PDU Set, such as the QNC enabling parameters and QoS parameters of the PDU Set.

[0072] The SMF may determine the QoS profile of one or more PDU Sets to be sent to the access network device based on the QNC parameters of the PDU Set granularity provided by the PCC rules sent by the PCF.

[0073] The QNC parameters of the PDU Set granularity provided by the PCC rule may be preset by the PCF, or may be determined according to the QoS parameters of the PDU Set provided by the Application Function (AF) or the Network Exposure Function (NEF).

[0074] In one implementation, the AF may request the QoS parameters of the PDU Set from the external network, and the external network may provide one or more QoS parameters of the same PDU Set in a priority order (e.g., from high to low or from low to high), and then send these QoS parameters to the NEF, which then sends these QoS parameters to the PCF.

[0075] In one implementation, if the AF is considered to be trusted by the operator, the AF may also interact directly with the PCF and send one or more QoS parameters of the same PDU Set to the PCF.

[0076] After receiving the QoS profiles of one or more PDU Sets sent by the SMF, the access network device can confirm the QoS status of the first PDU Set that is currently satisfied according to the QoS profile of the first PDU Set in the QoS profiles of the one or more PDU Sets, and send a first indication message to the SMF.

[0077] The first PDU Set may be any one of the one or more PDU Sets or any multiple PDU Sets, which is not limited in this application.

[0078] The first indication information may be used to indicate QoS information of a first PDU Set in one or more PDU Sets, for example, whether the QoS of the first PDU Set can be met.

[0079] In some embodiments, the method may further include:

[0080] Receive alternative QoS profiles for one or more PDU Sets sent by SMF, as well as a priority list of the alternative QoS profiles.

[0081] In one implementation, the access network device may also receive alternative QoS profiles for one or more PDU Sets sent by the SMF, and a priority list of alternative QoS profiles for each PDU Set.

[0082] The SMF may determine the candidate QoS profiles and the priority list of the candidate QoS profiles for one or more PDU Sets to be sent to the access network device based on the QNC parameters of the PDU Set granularity provided by the PCC rules sent by the PCF.

[0083] In some embodiments, the QNC parameters may include QNC enabling parameters and QoS parameters.

[0084] The QNC enable parameter is a parameter used to indicate whether to enable or disable the notification control function for the PDU Set.

[0085] The QoS parameters of a PDU Set may include one or more of the following:

[0086] (1)PDU Set Delay Budget (PSDB)

[0087] (2)PDU Set Error Rate (PSER)

[0088] (3)PDU Set Integrated Handling Information (PSIHI)

[0089] (4)PDU Set Averaging Window

[0090] (5)PDU Set UL-guaranteed bitrate.

[0091] (6)PDU Set DL-guaranteed bitrate.

[0092] The QNC enabling parameters of the PDU Set may be obtained by extending the existing QNC enabling parameters, or may be newly defined QNC enabling parameters.

[0093] The QoS parameters of PDU Set may be extended in the existing optional QoS parameter set, or an optional QoS parameter set corresponding to an independent PDU Set granularity may be added and the QoS parameters of PDU Set may be defined therein.

[0094] The access network equipment in the embodiments of the present application may include AN or RAN in the fifth generation mobile communication (5G) network system, or a network element having functions similar to AN or RAN in a future network system (such as 6G).

[0095] The PCF in the embodiments of the present application may include a PCF in a 5G network system, or a network element in a future network system (such as 6G) having functions similar to those of a PCF.

[0096] The SMF in the embodiments of the present application may include the SMF in a 5G network system, or a network element in a future network system (such as 6G) having functions similar to those of the SMF.

[0097] The QoS parameter notification control method provided in the embodiment of the present application enables the access network device to perform QoS parameter notification at the PDU Set granularity based on the QNC parameters at the PDU Set granularity contained in the received QoS configuration file, thereby expanding the scope of application of QoS notification control.

[0098] In some embodiments, the QoS information of the first PDU Set in the one or more PDU Sets includes one or more of the following:

[0099] first QoS information, where the first QoS information is used to indicate that the QoS of the first PDU Set cannot be met;

[0100] Second QoS information, where the second QoS information is used to indicate that the QoS of the first PDU Set can be met;

[0101] A first candidate QoS profile, where the first candidate QoS profile is a candidate QoS profile with the highest priority among the candidate QoS profiles of the first PDU Set that can currently be matched;

[0102] The third QoS information is used to indicate that the access network device cannot match the lowest priority alternative QoS profile of the first PDU Set.

[0103] Specifically, the first indication information sent by the access network device to the SMF can be used to indicate the QoS information of the first PDU Set in different situations.

[0104] In one embodiment, when the QoS of the first PDU Set cannot be met (for example, the QoS parameters in the QoS configuration file of the first PDU Set cannot be met), the access network device may send a first indication message to the SMF to indicate the first QoS information, that is, send a first indication message to the SMF, and the first indication message is used to indicate that the QoS of the first PDU Set cannot be met (can no longer be guaranteed).

[0105] In one embodiment, when the QoS of the first PDU Set can be met (for example, the QoS parameters in the QoS configuration file of the first PDU Set can be met), the access network device can send a first indication message to the SMF to indicate the second QoS information, that is, send the first indication message to the SMF, and the first indication message is used to indicate that the QoS of the first PDU Set can be met (can again be guaranteed).

[0106] In one implementation, when the access network device receives one or more alternative QoS profiles of PDU Sets sent by SMF, and a priority list of alternative QoS profiles, if the QoS of the first PDU Set cannot be met, but the access network device can match the alternative QoS profile of the first PDU Set, then the first indication information can be used to indicate the first alternative QoS profile in addition to indicating that the QoS of the first PDU Set cannot be met. The first alternative QoS profile is the alternative QoS profile with the highest priority among the alternative QoS profiles of the first PDU Set that the access network device can currently match.

[0107] In one embodiment, when the access network device receives alternative QoS profiles of one or more PDU Sets and a priority list of alternative QoS profiles sent by the SMF, if the QoS of the first PDU Set cannot be met and the alternative QoS profiles of the first PDU Set cannot be matched, then the first indication information, in addition to being used to indicate that the QoS of the first PDU Set cannot be met, can also be used to indicate third QoS information, that is, the first indication information can also be used to indicate that the access network device cannot match the lowest priority alternative QoS profile of the first PDU Set.

[0108] In some embodiments, sending the first indication information to the SMF includes:

[0109] The first indication information is sent through a tunnel between the access network device and a PDU session anchor (PDU Session Anchor, PSA) user plane function (UserPlane Function, UPF).

[0110] Specifically, when the access network device sends the first indication information to the SMF, the first indication information can be first sent to the PSA UPF through the tunnel between the access network device and the PSAUPF. After receiving the first indication information, the PSA UPF sends the first indication information to the SMF.

[0111] In some embodiments, the access network device may also send the first indication information to the SMF through the control plane. For example, the access network device may send the first indication information to the access and mobility management function (AMF), and then the AMF sends the first indication information to the SMF.

[0112] In some embodiments, receiving a QoS profile of one or more PDU Sets sent by an SMF includes:

[0113] During the PDU session establishment process, receiving the QoS profile of one or more PDU Sets sent by the SMF; or,

[0114] During the PDU session modification process, receiving the QoS profile of one or more PDU Sets sent by the SMF; or,

[0115] When the PDU session is switched to the access network device, the QoS profile of one or more PDU Sets sent by the SMF is received.

[0116] Specifically, after the terminal served by the access network device initiates a PDU session establishment request, during the PDU session establishment process, the access network device can receive one or more PDU Set QoS profiles sent by the SMF. The one or more PDU Set QoS profiles sent by the SMF can be included in the session establishment response message.

[0117] After the terminal served by the access network device initiates a PDU session modification request, during the PDU session modification process, the access network device can receive one or more PDU Set QoS profiles sent by the SMF. The one or more PDU Set QoS profiles sent by the SMF can be included in the session modification response message.

[0118] When the terminal initiates a PDU session switching request and requests to switch the PDU session from other network devices to the access network device, the access network device can receive the QoS profile of one or more PDU Sets sent by the SMF. The QoS profile of one or more PDU Sets sent by the SMF can be included in the path switching response message.

[0119] In some embodiments, receiving one or more alternative QoS profiles of a PDU Set sent by an SMF, and a priority list of the alternative QoS profiles, includes:

[0120] During the PDU session establishment process, receiving one or more alternative QoS profiles of the PDU Set and a priority list of the alternative QoS profiles sent by the SMF; or,

[0121] During the PDU session modification process, receiving one or more alternative QoS profiles of the PDU Set sent by the SMF, and a priority list of the alternative QoS profiles; or,

[0122] When the PDU session is switched to the access network device, the alternative QoS profiles of one or more PDU Sets and the priority list of the alternative QoS profiles are received from the SMF.

[0123] Specifically, after the terminal served by the access network device initiates a PDU session establishment request, during the PDU session establishment process, the access network device can receive one or more alternative QoS profiles of the PDU Set and a priority list of the alternative QoS profiles sent by the SMF. The alternative QoS profiles of the one or more PDU Sets and the priority list of the alternative QoS profiles sent by the SMF can be included in the session establishment response message.

[0124] After the terminal served by the access network device initiates a PDU session modification request, during the PDU session modification process, the access network device may receive one or more alternative QoS profiles of the PDU Set and a priority list of the alternative QoS profiles sent by the SMF. The alternative QoS profiles of the one or more PDU Sets and a priority list of the alternative QoS profiles sent by the SMF may be included in a session modification response message.

[0125] When the terminal initiates a PDU session switching request and requests to switch the PDU session from other network devices to the access network device, the access network device can receive one or more alternative QoS profiles of the PDU Set and the priority list of the alternative QoS profiles sent by the SMF. The alternative QoS profiles of one or more PDU Sets and the priority list of the alternative QoS profiles sent by the SMF can be included in the path switching response message.

[0126] Figure 3 The second flow chart of the QoS parameter notification control method provided in the embodiment of the present application is applied to PCF, such as Figure 3 As shown, the method comprises the following steps:

[0127] Step 300: Determine a PCC rule, where the PCC rule includes a QNC parameter of a PDU Set granularity.

[0128] Step 301: Send PCC rules to SMF.

[0129] Specifically, in the QoS parameter notification control scenario, the PCF may determine a PCC rule including a QNC parameter of a PDU Set granularity, and then send the PCC rule to the SMF.

[0130] In some embodiments, determining the PCC rule may include:

[0131] The PCC rule is determined according to the QoS parameters of the PDU Set provided by the application function AF or the network open function NEF.

[0132] In one implementation, the AF may request the QoS parameters of the PDU Set from the external network, and the external network may provide one or more QoS parameters of the same PDU Set in a priority order (e.g., from high to low or from low to high), and then send these QoS parameters to the NEF, which then sends these QoS parameters to the PCF.

[0133] In one implementation, if the AF is considered to be trusted by the operator, the AF may also interact directly with the PCF and send one or more QoS parameters of the same PDU Set to the PCF.

[0134] In some embodiments, the PCF may also determine the PCC rule according to the QNC parameter of the PDU Set granularity preset by the PCF itself.

[0135] After SMF receives the PCC rules sent by PCF, it can determine the QoS profiles of one or more PDU Sets to be sent to the access network device according to the QNC parameters of the PDU Set granularity contained in the PCC rules, and then send the QoS profiles of one or more PDU Sets to the access network device. The access network device can confirm the QoS status of the first PDU Set that is currently met according to the QoS profile of the first PDU Set in the QoS profiles of the one or more PDU Sets, and send the first indication information to SMF.

[0136] The first indication information may be used to indicate QoS information of a first PDU Set in one or more PDU Sets, for example, whether the QoS of the first PDU Set can be met.

[0137] The QoS parameter notification control method provided in the embodiment of the present application can include QNC parameters of PDU Set granularity in the PCC rules determined by the PCF, so that the access network equipment can perform QoS parameter notification at PDU Set granularity, thereby expanding the scope of application of QoS notification control.

[0138] In some embodiments, the method further comprises:

[0139] Receive second indication information sent by the SMF, where the second indication information is used to indicate one or more of the following:

[0140] The access network device determines that a first QoS parameter can be met, where the first QoS parameter is a QoS parameter corresponding to the QoS configuration file of the first PDU Set;

[0141] The access network device determines that a first QoS parameter cannot be satisfied, where the first QoS parameter is a QoS parameter corresponding to the QoS profile of the first PDU Set;

[0142] The access network device determines that a second QoS parameter can be met, where the second QoS parameter is a QoS parameter corresponding to a first candidate QoS profile, and the first candidate QoS profile is a candidate QoS profile with the highest priority among the candidate QoS profiles of the first PDU Set that the access network device can currently match;

[0143] The access network device determines that a third QoS parameter cannot be satisfied, where the third QoS parameter is a QoS parameter corresponding to the alternative QoS profile of the first PDUSet with the lowest priority.

[0144] Specifically, the PCF may receive the second indication information sent by the SMF. The second indication information is determined by the SMF after receiving the first indication information sent by the access network device.

[0145] In one embodiment, when the first indication information is used to indicate that the QoS of the first PDU Set can be met, the second indication information can be used to indicate that the current access network device determines that the first QoS parameter can be met, and the first QoS parameter can be the QoS parameter corresponding to the QoS profile of the first PDU Set (i.e., the QoS parameter configured in the QoS profile of the first PDU Set), such as PDU Set delay budget, PDU Set error rate, etc.

[0146] In one implementation, when the first indication information is used to indicate that the QoS of the first PDU Set cannot be met, as well as the first alternative QoS profile, the second indication information may be used to indicate that the current access network device determines that the first QoS parameter cannot be met, but can meet the second QoS parameter. The second QoS parameter may be a QoS parameter corresponding to the first alternative QoS profile (i.e., a QoS parameter configured in the first alternative QoS profile), such as a PDU Set delay budget, a PDU Set error rate, etc. Among them, the first alternative QoS profile is the alternative QoS profile with the highest priority among the alternative QoS profiles of the first PDU Set that the access network device can currently match.

[0147] The second indication information may also be directly used to indicate that the current access network device is determined to be able to meet the second QoS parameter.

[0148] In one implementation, when the first indication information is used to indicate that the QoS of the first PDU Set cannot be met, and the access network device cannot match the lowest priority alternative QoS profile of the first PDU Set, the second indication information can be used to indicate that the current access network device determines that the first QoS parameter cannot be met, and the third QoS parameter cannot be met. The third QoS parameter can be a QoS parameter corresponding to the alternative QoS profile of the first PDU Set with the lowest priority (i.e., a QoS parameter configured in the alternative QoS profile of the first PDU Set with the lowest priority), such as a PDU Set delay budget, a PDU Set error rate, etc.

[0149] The second indication information may also be directly used to indicate that the current access network device is determined to be unable to meet the third QoS parameter.

[0150] Figure 4 The third flow chart of the QoS parameter notification control method provided in the embodiment of the present application is applied to SMF, such as Figure 4As shown, the method comprises the following steps:

[0151] Step 400: Receive a PCC rule sent by a PCF, where the PCC rule includes a QNC parameter of a PDU Set granularity.

[0152] Step 401: Send one or more QoS configuration files of PDU Set to an access network device, where the QoS configuration files include QNC parameters of the PDU Set.

[0153] Specifically, the SMF may receive the PCC rules including the QNC parameters with PDU Set granularity sent by the PCF.

[0154] The QNC parameters of the PDU Set granularity provided by the PCC rule may be preset by the PCF, or may be determined according to the QoS parameters of the PDU Set provided by the AF or NEF.

[0155] After receiving the PCC rules sent by the PCF, the SMF can determine the QoS profiles of one or more PDU Sets according to the QNC parameters of the PDU Set granularity in the PCC rules, and send these QoS profiles to the access network device.

[0156] The QoS configuration file sent by SMF to the access network device may include QNC parameters of one or more PDU Sets. For example, if there are two PDU Sets that require QoS parameter notification control, the QNC parameters of these two PDU Sets may be included in one QoS configuration file or in two QoS configuration files. The QNC parameters of the PDU Set may be parameters related to the QoS notification control of the PDU Set, such as the QNC enabling parameters and QoS parameters of the PDU Set.

[0157] In some embodiments, the method may further include:

[0158] Send one or more alternative QoS profiles of PDU Set to the access network device, as well as a priority list of the alternative QoS profiles.

[0159] In one implementation, the SMF may determine, based on the QNC parameters of the PDU Set granularity provided by the PCC rules sent by the PCF, alternative QoS profiles for one or more PDU Sets to be sent to the access network device and a priority list of the alternative QoS profiles, and send them to the access network device.

[0160] The QoS parameter notification control method provided in the embodiment of the present application, SMF includes QNC parameters with PDU Set granularity in the QoS configuration file sent to the access network device, so that the access network device can perform QoS parameter notification with PDU Set granularity, thereby expanding the scope of application of QoS notification control.

[0161] In some embodiments, the method further comprises:

[0162] Receive first indication information sent by an access network device, where the first indication information is used to indicate QoS information of a first PDU Set in one or more PDU Sets.

[0163] Specifically, after sending one or more QoS profiles of PDU Set to the access network device, the access network device can confirm the QoS status of the first PDU Set that is currently satisfied according to the QoS profile of the first PDU Set in the one or more QoS profiles of PDU Set, and determine the first indication information. The SMF can receive the first indication information sent by the access network device.

[0164] The first indication information may be used to indicate QoS information of a first PDU Set in one or more PDU Sets, for example, whether the QoS of the first PDU Set can be met.

[0165] In some embodiments, the QoS information of the first PDU Set in the one or more PDU Sets includes one or more of the following:

[0166] first QoS information, where the first QoS information is used to indicate that the QoS of the first PDU Set cannot be met;

[0167] Second QoS information, where the second QoS information is used to indicate that the QoS of the first PDU Set can be met;

[0168] A first candidate QoS profile, where the first candidate QoS profile is a candidate QoS profile with the highest priority among the candidate QoS profiles of the first PDU Set that the access network device can currently match;

[0169] The third QoS information is used to indicate to the access network device that the access network device cannot match the lowest priority alternative QoS profile of the first PDUSet.

[0170] Specifically, the first indication information received by the SMF can be used to indicate the QoS information of the first PDU Set in different situations.

[0171] In one embodiment, when the QoS of the first PDU Set cannot be met (for example, the QoS parameters in the QoS profile of the first PDU Set cannot be met), the first indication information received by the SMF can be used to indicate the first QoS information, that is, the first indication information is used to indicate that the QoS of the first PDU Set cannot be met (can no longer be guaranteed).

[0172] In one embodiment, when the QoS of the first PDU Set can be met (for example, the QoS parameters in the QoS profile of the first PDU Set can be met), the first indication information received by the SMF can be used to indicate the second QoS information, that is, the first indication information is used to indicate that the QoS of the first PDU Set can be met (can again be guaranteed).

[0173] In one implementation, when the SMF sends one or more alternative QoS profiles of PDU Sets and a priority list of alternative QoS profiles to an access network device, if the QoS of the first PDU Set cannot be met, but the access network device can match the alternative QoS profile of the first PDU Set, then the first indication information can be used to indicate the first alternative QoS profile in addition to indicating that the QoS of the first PDU Set cannot be met. The first alternative QoS profile is the alternative QoS profile with the highest priority among the alternative QoS profiles of the first PDU Set that the access network device can currently match.

[0174] In one embodiment, when the SMF sends one or more alternative QoS profiles of PDU Sets and a priority list of alternative QoS profiles to an access network device, if the QoS of the first PDU Set cannot be met and the alternative QoS profiles of the first PDU Set cannot be matched, then the first indication information, in addition to being used to indicate that the QoS of the first PDU Set cannot be met, can also be used to indicate third QoS information, that is, the first indication information can also be used to indicate that the access network device cannot match the lowest priority alternative QoS profile of the first PDU Set.

[0175] In some embodiments, receiving first indication information sent by an access network device includes:

[0176] Receive first indication information sent by the access network device through a tunnel between the access network device and the PSA UPF.

[0177] Specifically, when the SMF receives the first indication information sent by the access network device, it may be receiving the first indication information sent by the PSA UPF. Prior to this, the access network device may send the first indication information to the PSA UPF through the tunnel between it and the PSA UPF.

[0178] In some embodiments, the SMF may also receive the first indication information sent by the access network device through the control plane. For example, the SMF may receive the first indication information sent by the access network device through the AMF.

[0179] In some embodiments, the method further comprises:

[0180] After receiving the first indication information sent by the access network device, the second indication information is sent to the PCF, where the second indication information is used to indicate one or more of the following:

[0181] The access network device determines that a first QoS parameter can be met, where the first QoS parameter is a QoS parameter corresponding to the QoS configuration file of the first PDU Set;

[0182] The access network device determines that a first QoS parameter cannot be satisfied, where the first QoS parameter is a QoS parameter corresponding to the QoS profile of the first PDU Set;

[0183] The access network device determines that a second QoS parameter can be met, where the second QoS parameter is a QoS parameter corresponding to a first candidate QoS profile, and the first candidate QoS profile is a candidate QoS profile with the highest priority among the candidate QoS profiles of the first PDU Set that the access network device can currently match;

[0184] The access network device determines that a third QoS parameter cannot be satisfied, where the third QoS parameter is a QoS parameter corresponding to the alternative QoS profile of the first PDUSet with the lowest priority.

[0185] Specifically, after receiving the first indication information sent by the access network device, the SMF can determine the second indication information based on the first indication information, and send the second indication information to the PCF.

[0186] In one embodiment, when the first indication information is used to indicate that the QoS of the first PDU Set can be met, the second indication information can be used to indicate that the current access network device determines that the first QoS parameter can be met, and the first QoS parameter can be the QoS parameter corresponding to the QoS profile of the first PDU Set (i.e., the QoS parameter configured in the QoS profile of the first PDU Set), such as PDU Set delay budget, PDU Set error rate, etc.

[0187] In one implementation, when the first indication information is used to indicate that the QoS of the first PDU Set cannot be met, as well as the first alternative QoS profile, the second indication information may be used to indicate that the current access network device determines that the first QoS parameter cannot be met, but can meet the second QoS parameter. The second QoS parameter may be a QoS parameter corresponding to the first alternative QoS profile (i.e., a QoS parameter configured in the first alternative QoS profile), such as a PDU Set delay budget, a PDU Set error rate, etc. Among them, the first alternative QoS profile is the alternative QoS profile with the highest priority among the alternative QoS profiles of the first PDU Set that the access network device can currently match.

[0188] The second indication information may also be directly used to indicate that the current access network device is determined to be able to meet the second QoS parameter.

[0189] In one implementation, when the first indication information is used to indicate that the QoS of the first PDU Set cannot be met, and the access network device cannot match the lowest priority alternative QoS profile of the first PDU Set, the second indication information can be used to indicate that the current access network device determines that the first QoS parameter cannot be met, and the third QoS parameter cannot be met. The third QoS parameter can be a QoS parameter corresponding to the alternative QoS profile of the first PDU Set with the lowest priority (i.e., a QoS parameter configured in the alternative QoS profile of the first PDU Set with the lowest priority), such as a PDU Set delay budget, a PDU Set error rate, etc.

[0190] The second indication information may also be directly used to indicate that the current access network device is determined to be unable to meet the third QoS parameter.

[0191] In some embodiments, the method further comprises:

[0192] Send third indication information to the terminal, where the third indication information is used to indicate QoS parameters corresponding to the first candidate QoS profile.

[0193] Specifically, after receiving the first indication information sent by the access network device, if the first indication information indicates the first alternative QoS profile, the SMF can send a third indication information to the terminal (for example, using NAS signaling to be transmitted to the terminal through the access network device), and the third indication information can be used to indicate the QoS parameters corresponding to the first alternative QoS profile (that is, the QoS parameters configured in the first alternative QoS profile).

[0194] In some embodiments, sending a QoS profile of one or more PDU Sets to an access network device includes:

[0195] During the PDU session establishment process, one or more PDU Set QoS profiles are sent to the access network device; or,

[0197] When the PDU session is switched to the access network device, a QoS profile of one or more PDU Sets is sent to the access network device.

[0198] Specifically, after the terminal served by the access network device initiates a PDU session establishment request, during the PDU session establishment process, the SMF may send one or more PDU Set QoS profiles to the access network device. The one or more PDU Set QoS profiles sent by the SMF may be included in the session establishment response message.

[0199] After the terminal served by the access network device initiates a PDU session modification request, during the PDU session modification process, the SMF may send one or more PDU Set QoS profiles to the access network device. The one or more PDU Set QoS profiles sent by the SMF may be included in the session modification response message.

[0200] When the terminal initiates a PDU session switching request and requests to switch the PDU session from other network devices to the access network device, the SMF can send one or more PDU Set QoS profiles to the access network device. The one or more PDU Set QoS profiles sent by the SMF can be included in the path switching response message.

[0201] In some embodiments, sending one or more candidate QoS profiles of a PDU Set and a priority list of the candidate QoS profiles to an access network device includes:

[0203] During the PDU session modification process, one or more alternative QoS profiles of the PDU Set and a priority list of the alternative QoS profiles are sent to the access network device; or,

[0204] When the PDU session is switched to the access network device, one or more alternative QoS profiles of the PDU Set and a priority list of the alternative QoS profiles are sent to the access network device.

[0205] Specifically, after the terminal served by the access network device initiates a PDU session establishment request, during the PDU session establishment process, the SMF may send one or more alternative QoS profiles of the PDU Set and a priority list of the alternative QoS profiles to the access network device. The alternative QoS profiles of the one or more PDU Sets and the priority list of the alternative QoS profiles sent by the SMF may be included in the session establishment response message.

[0208] The methods provided in the embodiments of the present application are based on the same application concept, so the implementation of each method can refer to each other, and the repeated parts will not be repeated.

[0209] The following describes the methods provided in the above embodiments of the present application by using examples of specific application scenarios.

[0210] Example 1: QNC process at PDU Set granularity.

[0211] Figure 5 A fourth flow chart of the QoS parameter notification control method provided in the embodiment of the present application is as follows: Figure 5 As shown, the method comprises the following steps:

[0212] 0. (Optional step) The AF provides the Alternative QoS Parameter with PDU Set granularity to the NEF / PCF.

[0213] 1. PCC Rule extends the QoS notification control parameters at the PDU Set granularity, mainly extending the PDU Set Qos parameters in the Alternative QoS Parameter Sets.

[0214] Among them, the QoS notification control parameters of the PDU Set granularity extended by the PCC Rule are shown in Table 1.

[0215] Table 1

[0216]

[0217]

[0218]

[0219]

[0220]

[0221]

[0222]

[0223] 2. Based on the QNC related parameters provided by the PCC Rule, the SMF notifies the radio access network equipment (RAN) of the notification control related parameters of the PDU Set granularity through the QoS profile (QoS profile) / alternative QoS profile (Alternative QoS profile) (or the sub alternative QoS profile corresponding to the PDU Set granularity).

[0224] 3a. (Scenario without Alternative QoS profile) For a given GBR QoS flow, if the QNC function with PDU Set granularity is enabled, when the RAN determines that the PDU Set QoS parameters in the QoS profile can no longer be guaranteed / can be guaranteed again, the RAN shall send a notification of "PDU Set QoS can no longer be guaranteed / can be guaranteed again" to the SMF.

[0225] 3b. (Scenario with Alternative QoS profile) For a given GBR QoS flow, if the QNC function at PDU Set granularity is enabled, when the RAN determines that the PDU Set QoS parameters in the QoS profile cannot be met, and the QoS currently meeting the PDU Set granularity can be matched to an Alternative QoS profile / SubAlternative QoS profile at a certain PDU Set granularity in the priority order, the RAN shall send a notification of "PDU Set QoS can no longer be guaranteed" to the SMF and indicate a reference to the matching Alternative QoS profile / Sub Alternative QoS profile at the highest priority PDU Set granularity. When an Alternative QoS profile / SubAlternative QoS profile at a certain PDU Set granularity cannot be matched, the RAN shall send a notification of "PDU Set QoS can no longer be guaranteed" to the SMF and indicate that the Alternative QoS profile / Sub Alternative QoS profile at the lowest priority PDU Set granularity cannot be met.

[0226] If the RAN has sent a notification of "PDU Set QoS can no longer be guaranteed" to the SMF, and the RAN determines that the currently satisfied PDU Set QoS is different (better or worse) than the situation indicated in the last notification, the RAN shall send a notification to the SMF (i.e. "PDU Set QoS can no longer be guaranteed" or "PDU Set QoS can be guaranteed again") and indicate the current situation.

[0227] Description: The current situation is that the QoS profile can be met (implicitly indicated by the "PDU Set QoS can be guaranteed again" notification itself), an Alternative QoS profile / Sub Alternative QoS profile with a different PDU Set granularity (than last notification) can be met, or an Alternative QoS profile / Sub Alternative QoS profile with the lowest priority PDU Set granularity cannot be met.

[0228] 4a. (Scenario without Alternative QoS profile) After receiving the notification of "PDU Set QoS can no longer be guaranteed" or "PDU Set QoS can be guaranteed again" from RAN, SMF can forward the notification to PCF.

[0229] 4b. (Scenario with Alternative QoS profile) Upon receiving the notification of "PDU Set QoS can no longer be guaranteed" or "PDU Set QoS can be guaranteed again" from the RAN and the reference information of the Alternative QoS profile / Sub Alternative QoS profile with relevant PDU Set granularity, the SMF can indicate to the PCF the current situation met by the RAN.

[0230] 5. (With Alternative QoS profile scenario) If the PCF does not indicate differently (for example, re-issuing PCC rule or modifying PCC rule), the SMF uses NAS signaling (which is sent transparently through RAN) to notify the terminal (also known as User Equipment (UE)) about the changes of PDU Set QoS parameters (such as 5G service quality indicator, guaranteed bit rate, etc.), and RAN implements these PDU Set QoS parameters for PDU Set after QNC.

[0231] Example 2: PDU Set granularity QNC function in non-roaming and roaming with local breakout scenarios.

The N2 session management information includes the QoS Flow Identifier (QFI) and an indication that the PDU Set QoS target cannot be achieved or can be achieved again.

[0241] When the PDU Set QoS target cannot be achieved, if the RAN is configured with an Alternative QoS Profile priority list, the N2 session management information indicates a reference to an Alternative QoS Profile of PDU Set granularity that matches the PDU Set granularity QoS currently being implemented by the RAN, or indicates an Alternative QoS Profile of PDU Set granularity that does not meet the lowest priority.

[0312] 5. UPF sends the N3 End marker to the Source NG-RAN, and the Source NG-RAN forwards the N3End marker to the Target NG-RAN.

[0317] 9. Registration Procedure

[0318] The Alternative QoS Profile in the QNC process can also be a subAlternative QoS Profile with an independent PDU set granularity.

[0319] The QNC process in step 1b-2 is independent of the QNC process in step 6-7. The QNC process at the PDUSet granularity during the PDU session switching process is one of the above processes.

[0320] Example 5: AF provides Alternative PDU Set Qos Parameter to NEF / PCF.

[0321] Fig. 9 A flow chart of the AF providing Alternative PDU Set Qos Parameter according to an embodiment of the present application is as follows: Fig. 9 As shown, the process includes the following steps:

[0322] 1. AF sends an AF session creation request (Nnef_AFsess ionWithQoS_Createrequest) containing QoS to NEF, and extends Alternative PDU Set QoS Parameter in the session.

[0323] The AF may provide Alternative PDU Set QoS requirements in order of priority (e.g., indicating a preference for QoS requirements with which the service may operate), including:

[0324] When the AF requests the network to provide QoS references to the QoS, one or more PDU Set QoS reference parameters are provided in priority order.

[0325] When the AF requests the network to provide QoS with individual QoS parameters, one or more requested PDU Set QoS parameter sets are provided in priority order.

[0326] 2. NEF performs authorization.

[0327] 3. NEF sends a policy authorization creation request (Npcf_PolicyAuthorization_Createrequest) to PCF, and forwards the received parameters in the request to PCF (including the newly added Alternative PDU SetQoS Parameter parameters).

[0328] If the AF is considered to be trusted by the operator, the AF can interact directly with the PCF using the Npcf_PolicyAuthorization_Create request message and extend the Alternative PDU Set QoSParameter parameter in the parameter.

[0329] 3a. NEF sends a QoS and TSC assistance information creation request (Ntsctsf_QoSandTSCAssistance_Create request) to the Time Sensitive communication Time Synchronization function (TSCTSF).

[0330] 3b. TSCTSF sends a policy authorization create request or update request (Npcf_PolicyAuthorization_Create request or Update request) to PCF.

[0331] 4. PCF sends a policy authorization creation response (Npcf_PolicyAuthorization_Createresponse) to NEF.

[0332] If the request received by the PCF is authorized, the PCF can derive the QoS parameters required by the PCC rules based on the parameters provided by the AF / NEF, including the Alternative PDU Set QoS parameter set derived based on the newly added Alternative PDU Set QoS Parameter parameter (in the same priority order indicated by the AF).

[0333] The SMF may notify the RAN of the notification control related parameters of the PDU Set granularity through the QoS profile / Alternative QoS profile (or the sub Alternative QoS profile corresponding to the PDU Set granularity) based on the QNC related parameters (including the Alternative PDU Set QoS parameter set) provided by the PCC Rule.

[0334] When the PCF notifies the AF that the QoS target can no longer be achieved, the PCF shall add support for a PDU Set QoS reference parameter or an indication of the corresponding set of requested Alternative PDU Set QoS parameters (does not meet the QoS Profile, but meets the alternative QoS Profile). Or add a minimum priority PDU Set QoS reference that cannot meet the Alternative service requirements or an indication of the minimum priority set of requested Alternative PDU Set QoS parameters (does not meet the minimum priority QoS Profile).

[0335] 4a. PCF sends a policy authorization create response or update response (Npcf_PolicyAuthorization_Create response or Update response) to TSCTSF.

[0336] 4b. TSC TSF sends a QoS and TSC assistance information creation response (Ntsctsf_QoSandTSCAssistance_Create response) to NEF.

[0337] 5. NEF sends an AF session creation response including QoS to AF (Nnef_AFsessionWithQoS_Createresponse).

[0338] 6. NEF sends a policy authorization subscription (Npcf_PolicyAuthorization_Subscribe) to PCF.

[0339] 6a. TSCTSF sends a policy authorization subscription (Npcf_PolicyAuthorization_Subscribe) to PCF.

[0340] 7. PCF sends a policy authorization notification (Npcf_PolicyAuthorization_Notify) to NEF.

[0341] 7a. PCF sends a policy authorization notification (Npcf_PolicyAuthorization_Notify) to TSC TSF.

[0342] 7b. TSCTSF sends QoS and TSC assistance information notification (Ntsctsf_Qo SandTSCAssistance_Notify) to NEF.

[0343] 8. NEF sends an AF session notification including QoS (Nnef_AFsessionWithQoS_Notify) to AF.

[0344] The Alternative QoS Profile in the QNC process can also be a subAlternative QoS Profile with an independent PDU set granularity.
