Description

Communication method and device, communication equipment, communication system, and storage medium Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to communication methods and devices, communication equipment, communication systems, and storage media. Background Art

[0002] The fifth-generation mobile communication system (5G) communication services generally correspond to service quality (QoS) requirements of ultra-low latency, ultra-large bandwidth, and ultra-large capacity. However, at present, wireless resources are changing dynamically, and it is very likely that the current wireless resources will not be able to meet the QoS requirements of communication services. For example, the current wireless resources cannot meet QoS requirements such as latency, bandwidth, or capacity. In this case, how to ensure the QoS requirements of communication services is a technical problem that needs to be solved urgently.

[0091] The embodiments of the present disclosure provide a communication method and apparatus, a communication device, a communication system, and a storage medium.

[0092] In a first aspect, an embodiment of the present disclosure provides a communication method, performed by an AF, the method including:

[0093] Sending a first request, where the first request is used to request session resources for a first service; the first request includes at least one of the following: first information indicating a first quality of service (QoS) profile corresponding to a protocol data unit (PDU), second information indicating a second QoS profile corresponding to a PDU set, a first indication, at least one first alternative QoS profile, third information indicating a priority of the at least one first alternative QoS profile, at least one second alternative QoS profile, and fourth information indicating a priority of the at least one second alternative QoS profile;

[0094] The first candidate QoS profile is used to replace the first QoS profile, and the second candidate QoS profile is used to replace the second QoS profile;

[0095] The first indication is used for at least one of the following:

[0096] Enable a first function, the first function including at least one of the following: a PDU set extension function of the first alternative QoS profile; a support function of the second alternative QoS profile; a support function of the first alternative QoS profile and the second alternative QoS profile; the first alternative QoS profile and the second alternative QoS profile are interchangeable; the first alternative QoS profile and the second alternative QoS profile are interchangeable;

[0097] Indicating that the second alternative QoS profile can replace the first alternative QoS profile;

[0098] Indicating that the first candidate QoS profile can replace the second candidate QoS profile;

[0099] Indicates that the first QoS profile can be replaced by the second QoS profile or the second QoS profile can be replaced by the first QoS profile based on the priorities corresponding to the first QoS profile and the second QoS profile respectively, and indicates that the first alternative QoS profile can be replaced by the second alternative QoS profile or the second alternative QoS profile can be replaced by the first alternative QoS profile based on the priorities corresponding to the first alternative QoS profile and the second alternative QoS profile respectively.

[0100] In the above embodiment, the first request sent by the AF includes at least one of the following: first information, second information, a first indication, at least one first alternative QoS profile, and at least one second alternative QoS profile. The first information can be used to indicate a first QoS profile corresponding to a protocol data unit (PDU), the second information can be used to indicate a second QoS profile corresponding to a PDU set, the first alternative QoS profile is used to replace the first QoS profile, the second alternative QoS profile is used to replace the second QoS profile, and the first indication can be used to indicate that the first QoS profile and the second QoS profile are interchangeable, and the first alternative QoS profile and the second alternative QoS profile are interchangeable. It can be seen from this that when AF requests session resources for the first service, it can also provide a first QoS profile, a second QoS profile, a first alternative QoS profile, and a second alternative QoS profile, and also provide a first indication to indicate that the first QoS profile, the second QoS profile, the first alternative QoS profile, and the second alternative QoS profile can be replaced with each other. Therefore, when the access network device subsequently schedules resources for the first service, if the current transmission resources of the access network device cannot meet the QoS requirements of the currently used QoS profile, the access network device can replace the currently used QoS profile based on the first QoS profile, the second QoS profile, the first alternative QoS profile, and the second alternative QoS profile according to the first indication, so that the QoS requirements of the replaced QoS profile can be met by the current transmission resources of the access network device, thereby realizing dynamic adaptive scheduling of the QoS requirements of the first service, ensuring that the QoS requirements of the first service can be guaranteed, so that the first service can be smoothly executed, and improving user experience.

[0101] In addition, in the above embodiment, the first request sent by the AF may also include third information for indicating the priority of at least one first alternative QoS profile and fourth information for indicating the priority of at least one second alternative QoS profile. Thus, the access network device can replace the QoS profile currently used by the access network device based on the priority of the first alternative QoS profile and / or the priority of the second alternative QoS profile, so that the replaced QoS profile can be adapted to the current transmission resources of the access network device and has a higher priority, thereby ensuring the accuracy of the QoS profile replacement.

[0102] In conjunction with some embodiments of the first aspect, in some embodiments, the first QoS profile is used to schedule PDUs in the service data flow SDF of the first service so that the PDUs meet the QoS requirements of the first QoS profile; the second QoS profile is used to schedule a PDU set in the SDF of the first service so that the PDU set meets the QoS requirements of the second QoS profile;

[0103] The first alternative QoS profile is used to replace the first QoS profile to schedule the PDU, and the second alternative QoS profile is used to replace the second QoS profile to schedule the PDU set.

[0104] In the above embodiment, by replacing the first QoS profile with the first alternative QoS profile, or by replacing the second QoS profile with the second alternative QoS profile, when the QoS requirements of the first QoS profile or the second QoS profile cannot be met by the current transmission resources of the access network device, the first alternative QoS profile or the second alternative QoS profile can be used to schedule the PDU or PDU set in the SDF of the first service, thereby realizing dynamic adaptive scheduling of the QoS requirements of the first service, ensuring that the QoS requirements of the first service can be guaranteed, so that the first service can be smoothly executed, and improving user experience.

[0105] In conjunction with some embodiments of the first aspect, in some embodiments, the second QoS profile may replace the first QoS profile; or,

[0106] The first QoS profile may replace the second QoS profile; or

[0107] The second alternative QoS profile may replace the first alternative QoS profile; or

[0108] The first alternative QoS profile may replace the second alternative QoS profile;

[0109] Wherein, replacing the first QoS profile with the second QoS profile includes: changing the profile from a first state to a second state;

[0110] The replacing the second QoS profile with the first QoS profile includes: changing from the second state to the first state;

[0111] The replacing the first candidate QoS profile with the second candidate QoS profile includes: changing a profile from a third state to a fourth state;

[0112] The replacing the second candidate QoS profile with the first candidate QoS profile includes: changing from a fourth state to a third state;

[0113] The first state includes: scheduling the PDU in the SDF of the first service using the first QoS profile;

[0114] The second state includes: scheduling a PDU set in the SDF of the first service using the second QoS profile;

[0115] The third state includes: scheduling the PDUs in the SDF of the first service using the first alternative QoS profile;

[0116] The fourth state includes: scheduling the PDU set in the SDF of the first service using the second alternative QoS profile.

[0117] In the above embodiment, the first QoS profile and the second QoS profile can be replaced with each other, or the first alternative QoS profile and the second alternative QoS profile can be replaced with each other. Since the first QoS profile and the first alternative QoS profile are QoS profiles corresponding to the PDU, and the second QoS profile and the second alternative QoS profile are QoS profiles corresponding to the PDU set, by replacing the first QoS profile and the second QoS profile, or by replacing the first alternative QoS profile and the second alternative QoS profile, the access network device can realize the mutual change between the processing of the PDU granularity and the processing of the PDU set granularity when processing the first service, which can more effectively guarantee the end-to-end QoS requirements, better adapt to resource demand and allocation, coordinate end-to-end QoS resources, ensure the smooth execution of the first service, and improve user experience.

[0118] In conjunction with some embodiments of the first aspect, in some embodiments, the first candidate QoS profile includes at least one of the following:

[0119] a first QoS parameter corresponding to the PDU;

[0120] a second QoS parameter corresponding to the PDU set;

[0121] the first instruction;

[0127] The seventh information is used to indicate the priority corresponding to the second alternative QoS profile.

[0128] In conjunction with some embodiments of the first aspect, in some embodiments, the PDU set extension function of the first candidate QoS profile includes:

[0129] The first candidate QoS profile includes a second QoS parameter corresponding to the PDU set.

[0130] In conjunction with some embodiments of the first aspect, in some embodiments, the supporting functions of the second alternative QoS profile include:

[0131] The second alternative QoS profile is independent of the first alternative QoS profile.

[0132] In conjunction with some embodiments of the first aspect, in some embodiments, the supported functions of the first candidate QoS profile and the second candidate QoS profile include any one of the following:

[0133] The second candidate QoS profile is independent of the first candidate QoS profile and is included in the same profile;

[0134] The second candidate QoS profile is independent of the first candidate QoS profile and is not included in the same profile.

[0135] In the above embodiment, the contents included in the first alternative QoS profile, the contents included in the second alternative QoS profile, and the above-mentioned first function are specifically defined, so that the access network device can replace the QoS profile based on the current transmission resource adaptability of the access network device based on the contents included in the first alternative QoS profile, the contents included in the second alternative QoS profile, and the first function. This can effectively guarantee end-to-end QoS requirements, better adapt resource demand and allocation, coordinate end-to-end QoS resources, ensure the smooth execution of the first service, and improve user experience.

[0136] In conjunction with some embodiments of the first aspect, in some embodiments, the first indication is further used for at least one of the following:

[0137] Indicate a first condition, where the first condition is: a condition that needs to be met when the second QoS profile can replace the first QoS profile;

[0140] Indicates a fourth condition, which is a condition that needs to be met when the first alternative QoS profile can replace the second alternative QoS profile.

[0336] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0337] Step 2101: The application function (AF) sends a first request.

[0338] Optionally, when a first service needs to be executed, the AF may send a first request, which may be used to request session resources for the first service. Optionally, the first request may be used to establish a session for the first service, or may be used to update a session for the first service. The first service may be, for example, an Extended Reality Media (XRM) service, and the first request may be, for example, an AF session resource request or an AF request.

[0339] Optionally, the AF may send the first request to a first network element, and the first network element receives the first request. The first network element may be, for example, an NEF network element. Optionally, the AF may send the first request via an Nnef_AFsessionWithQoS_Create request.

[0342] Second information, the second information being used to indicate a second QoS profile corresponding to the PDU set;

[0343] First Instruction;

[0344] at least one first candidate QoS profile;

[0345] third information, the third information being used to indicate a priority of at least one first candidate QoS profile;

[0346] at least one second alternative QoS profile;

[0347] Fourth information, where the fourth information is used to indicate a priority of at least one second candidate QoS profile.

[0348] It should be noted that the above-mentioned "QoS configuration file" is only an exemplary name for the embodiment of the present disclosure. It can also be called "QoS specification file, QoS document, QoS file", etc., and the present disclosure does not make specific limitations on this.

[0349] The following is a detailed introduction to the content included in the above-mentioned first request.

[0350] Optionally, the above-mentioned first QoS profile may be a QoS profile corresponding to the PDU requested by the AF. The first QoS profile may include first QoS parameters corresponding to the PDU. The first QoS parameters may include, for example, at least one of the following: packet delay budget (PDB), packet error rate (PER), uplink guaranteed bit rate (UL-guaranteed bitrate), downlink guaranteed bit rate (DL-guaranteed bitrate), averaging window (Averaging window), and maximum data burst volume (Maximum Data Burst Volume); wherein the first QoS parameters may be used to define the QoS requirements corresponding to the PDU (i.e., PDB requirements, PER requirements, uplink guaranteed bit rate requirements, etc.), and the first QoS profile may be used to schedule the PDU in the service data flow (SDF) of the first service so that the PDU meets the QoS requirements of the first QoS profile; optionally, the above-mentioned first information may be directly the first QoS profile, or the first information may be indication information corresponding to the first QoS profile, for example, the first information may be a QoS reference (QoS Reference) corresponding to the first QoS profile, and the QoS reference may be, for example, a sequence number.

[0351] Optionally, the above-mentioned second QoS profile may be a QoS profile corresponding to the PDU set requested by the AF, and the second QoS profile may include a second QoS parameter corresponding to the PDU set, and the second QoS parameter may include, for example, at least one of the following: packet set delay budget (Packet Set Delay Budget), packet set error rate (Packet Set Error Rate), PDU set integrated handling information (PDU Set Integrated Handling Information, PSIHI), uplink guaranteed bit rate of the PDU set (UL-guaranteed bitrate), downlink guaranteed bit rate of the PDU set (DL-guaranteed bitrate), averaging window of the PDU set (Averaging window), maximum data burst size of the PDU set (Maximum Data Burst Volume); wherein the second QoS parameter can be used to define the QoS requirements corresponding to the PDU set (i.e., packet set delay budget requirement, packet set error rate requirement, uplink guaranteed bit rate requirement of the PDU set, etc.), and the second QoS profile is used to schedule the PDU set in the SDF of the first service so that the PDU set meets the QoS requirements of the second QoS profile; optionally, the above-mentioned second information can be directly the second QoS profile, or the second information can be indication information corresponding to the second QoS profile, for example, the second information can be a QoS reference corresponding to the second QoS profile.

[0352] Optionally, the difference between the above-mentioned PDU and PDU set may be: a PDU set may include multiple PDUs, wherein, when the scheduling granularity of the SDF of the first service is PDU, data transmission may be performed in units of "PDU", and when the scheduling granularity of the SDF of the first service is PDU set, data transmission may be performed in units of "PDU set", wherein, when data transmission is performed in units of "PDU set", the required communication resources, bandwidth, and capacity are larger, and the execution efficiency of the first service is also higher.

[0353] Optionally, the above-mentioned first alternative QoS profile can be used to schedule the PDU, and the first alternative QoS profile can be used to replace the first QoS profile to schedule the PDU. Optionally, the QoS requirement corresponding to the first alternative QoS profile is different from the QoS requirement corresponding to the first QoS profile. In some embodiments, the first alternative QoS profile may include a first QoS parameter corresponding to the PDU, wherein the parameter value of the first QoS parameter included in the first alternative QoS profile may be different from the parameter value of the first QoS parameter included in the first QoS profile, thereby making the QoS requirement corresponding to the first alternative QoS profile different from the QoS requirement corresponding to the first QoS profile. In addition, the parameter values ​​of the first QoS parameters included in different first alternative QoS profiles are also different, so that the QoS requirements corresponding to different first alternative QoS profiles are different.

[0354] Optionally, the aforementioned second alternative QoS profile can be used to schedule the PDU set, and the second alternative QoS profile can be used to replace the second QoS profile to schedule the PDU set. Optionally, the QoS requirement corresponding to the second alternative QoS profile is different from the QoS requirement corresponding to the second QoS profile. In some embodiments, the second alternative QoS profile may include a second QoS parameter corresponding to the PDU set, wherein the parameter value of the second QoS parameter included in the second alternative QoS profile may be different from the parameter value of the second QoS parameter included in the second QoS profile, thereby making the QoS requirement corresponding to the second alternative QoS profile different from the QoS requirement corresponding to the second QoS profile. Furthermore, the parameter values ​​of the second QoS parameters included in different second alternative QoS profiles are also different, so that the QoS requirements corresponding to different second alternative QoS profiles are different.

[0355] Optionally, in some embodiments, the first indication may be used for at least one of the following:

[0356] Enable the first function;

[0357] indicating that the second alternative QoS profile may replace the first alternative QoS profile;

[0358] indicating that the first candidate QoS profile may replace the second candidate QoS profile;

[0359] indicating that the first QoS profile may be replaced by the second QoS profile or the second QoS profile may be replaced by the first QoS profile based on the priorities respectively corresponding to the first QoS profile and the second QoS profile, and indicating that the first alternative QoS profile may be replaced by the second alternative QoS profile or the second alternative QoS profile may be replaced by the first alternative QoS profile based on the priorities respectively corresponding to the first alternative QoS profile and the second alternative QoS profile;

[0360] Indicates a first condition, where the first condition is a condition that must be met when the second QoS profile can replace the first QoS profile. For example, the condition may be a time condition that must be met when the second QoS profile can replace the first QoS profile. For example, when the time period is from 9:00 to 11:00 in the morning, network resources are generally sufficient. At this time, the second QoS profile can be used to replace the first QoS profile, and the SDF of the first service is processed at the granularity of the PDU set, thereby improving the processing efficiency of the first service.

[0361] Indicates a second condition, where the second condition is a condition that must be met when the first QoS profile can replace the second QoS profile. For example, it can be a time condition that must be met when the first QoS profile can replace the second QoS profile. For example, when the time period is from 9:00 to 11:00 p.m., network resources are generally congested. At this time, the first QoS profile can be used to replace the second QoS profile, and the SDF of the first service can be processed at the PDU granularity to adapt to the congested network resources.

[0362] Indicates a third condition, which is a condition that must be met when the second candidate QoS profile can replace the first candidate QoS profile. The third condition is similar to the first condition and is not repeated here.

[0363] Indicates the fourth condition, which is: the condition that needs to be met when the first alternative QoS profile can replace the second alternative QoS profile, where the fourth condition is similar to the second condition and will not be repeated here.

[0364] Optionally, the first function may include at least one of the following:

[0365] The PDU set extension function of the first alternative QoS profile; wherein the PDU set extension function of the first alternative QoS profile may include: including a second QoS parameter corresponding to the PDU set in the first alternative QoS profile;

[0366] The supporting function of the second alternative QoS profile may include: the second alternative QoS profile is independent of the first alternative QoS profile; that is, the second alternative QoS profile and the first alternative QoS profile are two independent and different profiles;

[0367] Support functions of the first alternative QoS profile and the second alternative QoS profile; wherein the support functions of the first alternative QoS profile and the second alternative QoS profile may include any of the following: the second alternative QoS profile is independent of the first alternative QoS profile and is included in the same profile; or the second alternative QoS profile is independent of the first alternative QoS profile and is not included in the same profile;

[0368] The first QoS profile and the second QoS profile can be replaced with each other;

[0369] The first candidate QoS profile and the second candidate QoS profile are interchangeable.

[0370] Optionally, in some embodiments, the above-mentioned “replacing the first QoS profile with the second QoS profile” may include: changing from a first state to a second state, wherein the first state includes: scheduling PDUs in the SDF of the first service using the first QoS profile; and the second state includes: scheduling a set of PDUs in the SDF of the first service using the second QoS profile;

[0371] Optionally, in some other embodiments, the above-mentioned “replacing the second QoS profile with the first QoS profile” may include: changing from the second state to the first state;

[0372] Optionally, in some other embodiments, the above-mentioned “replacing the first alternative QoS profile with the second alternative QoS profile” may include: changing from a third state to a fourth state, wherein the third state includes: scheduling the PDU in the SDF of the first service using the first alternative QoS profile; and the fourth state includes: scheduling the PDU set in the SDF of the first service using the second alternative QoS profile;

[0373] Optionally, in some other embodiments, the above-mentioned “replacing the second candidate QoS profile with the first candidate QoS profile” may include: changing from the fourth state to the third state.

[0374] In combination with the foregoing, optionally, in some embodiments, the first candidate QoS profile may include at least one of the following:

[0375] A first QoS parameter corresponding to the PDU;

[0376] A second QoS parameter corresponding to the PDU set;

[0377] First Instruction;

[0378] fifth information, where the fifth information may be used to indicate a priority corresponding to the first candidate QoS profile;

[0379] The sixth information is used to indicate the priorities corresponding to the first QoS parameter and the second QoS parameter in the first candidate QoS profile respectively.

[0380] It should be noted that, in some embodiments, when the first alternative QoS profile also includes the above-mentioned second QoS parameters, the first alternative QoS can also be used to replace the second QoS profile for scheduling the PDU set. At this time, the second QoS parameters in the first alternative QoS profile can be used to replace the second QoS profile based on the priority corresponding to the second QoS parameters in the first alternative QoS profile.

[0381] In some other embodiments, the second candidate QoS profile may include at least one of the following:

[0382] A second QoS parameter corresponding to the PDU set;

[0383] First Instruction;

[0384] The seventh information is used to indicate the priority corresponding to the second alternative QoS profile.

[0385] It can be seen from the above content that the first request, the first alternative QoS profile in the first request, and the second alternative QoS profile in the first request may include the above-mentioned first indication. Therefore, in some embodiments, the first request may not include the first indication, while the first alternative QoS profile in the first request and / or the second alternative QoS profile in the first request include the first indication. Alternatively, in other embodiments, the first request may directly include the first indication, and the first alternative QoS profile in the first request and / or the second alternative QoS profile in the first request also include the first indication. Alternatively, in still other embodiments, the first request may directly include the first indication, but the first alternative QoS profile in the first request and / or the second alternative QoS profile in the first request do not include the first indication.

[0386] It should also be noted that in some embodiments, the first QoS profile and the second QoS profile can be interchangeable based on at least one of a first indication, a first policy, a local configuration of the access network device, a priority, a first condition, and a second condition; and the first alternative QoS profile and the second alternative QoS profile can be interchangeable based on at least one of a first indication, a first policy, a local configuration of the access network device, a priority, a third condition, and a fourth condition. Optionally, the first policy can be an operator policy.

[0387] Optionally, in some embodiments, the first request may further include a service identifier corresponding to the first service. The service identifier may identify at least one of the following:

[0388] A business data flow of a first business;

[0389] A service data flow group of the first service, where the service data flow group can be used to identify all data flows in the first service group. For example, the service data flow group can be a multi-modal service ID;

[0390] Terminal address (UE address);

[0391] Terminal identifier (UE Identifier);

[0392] AF Identifier Application ID;

[0393] Flow description(s) corresponding to the first service;

[0394] Data Network Name (DNN) DNN corresponding to the first service;

[0395] Network Slice Selection Assistance Information (S-NSSAI) corresponding to the first service;

[0396] The protocol description feature may optionally include at least one of a media type, forward error correction coding usage, encryption description, and multi-stream connection QoS requirements.

[0397] In addition, it should be noted that in some embodiments, the AF may also subscribe to a first event or a second event, where the first event may, for example, be: the QoS profile used by the access network device is replaced, and the second event may, for example, be: the transmission resources of the access network device cannot meet the QoS requirements corresponding to the first QoS profile, the second QoS profile, the first alternative QoS profile, and the second alternative QoS profile. When the first event or the second event occurs, the AF needs to be notified.

[0398] Step 2102: The first network element authorizes the first request.

[0399] Optionally, in some embodiments, since the AF is not a network element of the core network, it may happen that the indication name of the same object in the AF is different from the indication name in the core network. Therefore, after receiving the first request sent by the AF, the first network element needs to perform some relevant mappings to convert the indication name mapping in the AF to the common indication name in the core network. For example, the mapping of the service identifier of the first service to the DNN and S-NSSAI, the mapping of the external application to the core network (CN) application identifier, and the mapping of the external terminal identifier to the terminal identifier within the CN (such as the user permanent identifier (SUbscription Permanent Identifier, SUPI)) based on the configuration file of the unified data management function (UDM) can be performed, or the mapping of the external to the internal first service group identifier can be performed based on the UDM configuration file.

[0400] Step 2103: The first network element sends a first request.

[0401] Optionally, the first network element may send the first request to the second network element, and the second network element may receive the first request. The second network element may be, for example, a PCF network element. For example, the first network element may send the first request to the second network element via an Npcf_PolicyAuthorization_Create request.

[0402] Optionally, the first network element may directly send the first request to the second network element, or the first network element may send the first request to the second network element through a time sensitive communication and time synchronization function (TSCTSF).

[0403] It should be noted that, in some embodiments, the above steps 2102 and 2103 are optional and may or may not be performed. Optionally, when the AF is a trusted AF, the AF may directly send the first request to the second network element. When the AF is an untrusted AF, the above steps 2102 and 2103 may be performed.

[0404] Step 2104: The second network element determines a first rule based on the first request.

[0405] Optionally, the first rule may include at least one of the following: a first indication, first information, second information, at least one first alternative QoS profile, third information, at least one second alternative QoS profile, and fourth information.

[0406] Optionally, the first rule may be, for example, a Policy and Charging Control (PCC) rule.

[0407] Step 2105: The second network element sends the first rule to the third network element.

[0408] Optionally, the third network element may be, for example, an SMF network element.

[0409] Optionally, the second network element may send the first rule by initiating an SM Policy Association Modification Request (SM Policy Association Modification Request) to a third network element.

[0410] Optionally, in some embodiments, the second network element may also enable a QoS notification control mechanism, which may, for example, include notifying the second network element when the QoS profile used by the access network device is replaced, or when the transmission resources of the access network device cannot meet the QoS requirements corresponding to the first QoS profile, the second QoS profile, the first alternative QoS profile, and the second alternative QoS profile.

[0411] Step 2106: The second network element sends a first response to the first network element.

[0412] Optionally, the first response may be used to respond to the first request sent by the first network element to the second network element. For example, the first response may be Npcf_Policy Authorization_Create response.

[0413] Step 2107: The first network element sends a second response to the AF.

[0414] Optionally, the second response may be used to respond to the first request sent by the AF to the first network element, and the first response may be, for example, Nnef_AFsessionWithQoS_Create response. Optionally, the second response may be used to inform the AF that the first request is authorized.

[0415] Step 2108: The third network element determines a second rule based on the first rule.

[0416] Optionally, the second rule may be, for example, a QoS rule, and the second rule may include at least one of the following: a first indication, first information, second information, at least one first alternative QoS profile, third information, at least one second alternative QoS profile, and fourth information.

[0417] Step 2109: The third network element sends a third response to the second network element.

[0418] Optionally, the third response may be, for example, SM Policy Association Modification Response (SM Policy Association Modification Response).

[0419] Step 2110: The third network element sends the second rule to the access network device.

[0420] Optionally, in some embodiments, when the third network element sends information (such as the second rule) to the access network device, it can be sent to the access network device through the Access and Mobility Management Function (AMF) network element on the control plane, or it can be sent to the access network device through the User Plane Function (UPF) network element on the user plane.

[0421] Optionally, the second rule may be, for example, a QoS rule.

[0422] It should be noted that, in combination with the above content, it can be seen that in the embodiment of the present disclosure, "when AF provides QoS requirements (or QoS demands or the above-mentioned first request), it carries one or more QoS profiles to the core network network element, so that when PCF decides on PCC rules, the QoS profile is synchronously carried to SMF, and finally when SMF generates QoS rules based on PCC rules, it determines the QoS profile, and then sends it to UPF and RAN (i.e., access network equipment) and terminal, so that RAN and terminal perform corresponding processing based on the QoS profile (such as the replacement of the above-mentioned QoS profile)". Optionally, in other embodiments, the QoS profile can also be generated by SMF. Optionally, SMF can synchronously generate the corresponding QoS profile when generating QoS rules based on PCC rules, and then send it to UPF and RAN (i.e., access network equipment) and terminal, so that RAN and terminal perform corresponding processing based on the QoS profile.

[0423] Step 2111: The access network device replaces the QoS profile it uses based on the second rule.

[0424] Optionally, in some embodiments, the method for an access network device to replace a QoS profile used by the access network device based on a second rule may include: in response to the access network device's current transmission resources being unable to meet the QoS requirements of the currently used QoS profile, the access network device selecting a target QoS profile from among the first QoS profile, the second QoS profile, at least one first candidate QoS profile, and at least one second candidate QoS profile, and replacing the currently used QoS profile with the target QoS profile. Optionally, the QoS requirements corresponding to the target QoS profile can be met by the access network device's current transmission resources, and the target QoS profile has the highest priority.

[0425] For example, it is assumed that the QoS profile currently used by the access network device is the second QoS profile, and there are three second alternative QoS profiles, namely, the second alternative QoS profile #1, the second alternative QoS profile #2, and the second alternative QoS profile #3. Among them, the QoS requirement of the second alternative QoS profile #1 is lower than the QoS requirement of the second QoS profile, and the QoS requirement of the second alternative QoS profile #1 is higher than the QoS requirement of the second alternative QoS profile #2, and the QoS requirement of the second alternative QoS profile #2 is higher than the QoS requirement of the second alternative QoS profile #3; at the same time, the priority of the second alternative QoS profile #1 is higher than the priority of the second alternative QoS profile #2, and the priority of the second alternative QoS profile #2 is higher than the priority of the second alternative QoS profile #3. At this time, if the current transmission resources of the access network device cannot meet the QoS requirements of the second QoS profile, for example, the current transmission resources of the access network device are relatively congested and cannot meet the packet error rate requirements required by the second QoS profile, then the QoS requirements can be downgraded. For example, if the current transmission resources of the access network device can meet the QoS requirements of the second alternative QoS profile #1, the QoS requirements of the second alternative QoS profile #2, and the QoS requirements of the second alternative QoS profile #3, then the second alternative QoS profile #1 with the highest priority can be determined as the target QoS profile, and the second alternative QoS profile #1 can be used to replace the QoS profile currently used by the access network device, thereby achieving QoS downgrade.

[0426] Optionally, in some further embodiments, after the first QoS profile used by the access network device is replaced with the first alternative QoS profile (i.e., after downgrading), if the transmission resources of the access network device can again meet the QoS requirements of the first QoS profile, the QoS profile used by the access network device can be replaced back to the first QoS profile; similarly, after the second QoS profile used by the access network device is replaced with the second alternative QoS profile (i.e., after downgrading), if the transmission resources of the access network device can again meet the QoS requirements of the second QoS profile, the QoS profile used by the access network device can be replaced back to the second QoS profile.

[0427] Optionally, in another embodiment, the method for the access network device to replace the QoS profile used by the access network device based on the second rule may include any one of the following:

[0428] In response to the QoS profile currently used by the access network device being the first QoS profile, if a first condition is met, replacing the first QoS profile with the second QoS profile;

[0429] In response to the QoS profile currently used by the access network device being the second QoS profile, if a second condition is met, replacing the second QoS profile with the first QoS profile;

[0430] In response to the QoS profile currently used by the access network device being the first candidate QoS profile, if a third condition is satisfied, replacing the first candidate QoS profile with the second candidate QoS profile;

[0431] In response to the QoS profile currently used by the access network device being the second candidate QoS profile, if a fourth condition is met, the second candidate QoS profile is replaced with the first candidate QoS profile.

[0432] Optionally, in other embodiments, the first QoS profile and the second QoS profile may be interchangeable based on at least one of a first indication, a first policy, a local configuration of the access network device, a priority, a first condition, and a second condition; and the first alternative QoS profile and the second alternative QoS profile may be interchangeable based on at least one of a first indication, a first policy, a local configuration of the access network device, a priority, a third condition, and a fourth condition. Optionally, the first policy may be an operator policy.

[0433] In the above embodiment, if the current transmission resources of the access network device cannot meet the QoS requirements of the currently used QoS profile, the access network device can replace the currently used QoS profile based on the first QoS profile, the second QoS profile, the first alternative QoS profile, and the second alternative QoS profile according to the first indication, so that the QoS requirements of the replaced QoS profile can be met by the current transmission resources of the access network device, thereby realizing dynamic adaptive scheduling of the QoS requirements of the first service, ensuring that the QoS requirements of the first service can be guaranteed, so that the first service can be executed smoothly, and improving user experience.

[0434] Moreover, in the above embodiment, the access network device can replace the QoS profile currently used by the access network device based on the priority of the first alternative QoS profile and / or the priority of the second alternative QoS profile, so that the replaced QoS profile can be adapted to the current transmission resources of the access network device and has a higher priority, thereby ensuring the accuracy of the QoS profile replacement.

[0435] Step 2112: The access network device sends the first message or the second message to the third network element.

[0436] Optionally, in some embodiments, in response to the access network device replacing the QoS profile, the access network device may send a first message, where the first message is used to indicate at least one of the following: replacement of the QoS profile, the replaced QoS profile, and a QoS flow identifier (QFI);

[0437] Optionally, in some further embodiments, in response to transmission resources of the access network device failing to meet QoS requirements corresponding to the first QoS profile, the second QoS profile, the first alternative QoS profile, and the second alternative QoS profile, a second message is sent. The second message may be used to indicate at least one of the following:

[0438] QFI;

[0439] The transmission resources of the access network device cannot meet the QoS requirements corresponding to the first QoS profile, the second QoS profile, the first alternative QoS profile, and the second alternative QoS profile.

[0440] Optionally, the access network device may send the first message or the second message to the third network element via a fourth network element, where the fourth network element may be, for example, an AMF network element. Optionally, the access network device may transmit the first message or the second message via an N2 message.

[0441] Optionally, in some embodiments, the above-mentioned first message or second message may be actively reported by the access network device, or may be requested by the second network element to the third network element, and then the third network element requests the access network device.

[0442] Step 2113: The third network element sends the first message or the second message to the second network element.

[0443] Step 2114: The second network element sends the first message or the second message to the first network element.

[0444] Step 2114: The first network element sends the first message or the second message to the AF.

[0445] Optionally, the second network element may also directly send the first message or the second message to the AF.

[0446] From the above content, it can be seen that when the QoS profile is replaced, the access network device will send a first message to the core network. When the transmission resources of the access network device cannot meet the QoS requirements corresponding to the first QoS profile, the second QoS profile, the first alternative QoS profile, and the second alternative QoS profile, the access network device will send a second message to the core network. The first message is used to indicate at least one of the following: the replacement of the QoS profile, the replaced QoS profile, and the QFI; the second message is used to indicate at least one of the following: the QFI, the transmission resources of the access network device cannot meet the QoS requirements corresponding to the first QoS profile, the second QoS profile, the first alternative QoS profile, and the second alternative QoS profile. Therefore, based on the first message or the second message, the core network can promptly know the processing status of the QoS profile by the access network device, and the core network will also send the first message or the second message to the AF, thereby ensuring that the AF, the core network, and the access network device have an aligned understanding of the relevant processes of the first service, thereby ensuring the stability of the first service.

For example, step S6301 may be implemented as an independent embodiment, and steps S6301+6302 may be implemented as independent embodiments, but are not limited thereto.

[0619] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0620] The following is an exemplary introduction to the above method.

[0621] FIG6D is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG6D , the method may include the following steps:

[0622] 1. The AF sends an AF session resource request (ie, the first request mentioned above), for example, by sending an AF session resource request (or AF request) via Nnef_AFsessionWithQoS_Create request.

[0623] Optionally, AF can provide a flexibility indication of PDU and PDU set QoS processing (i.e., the first indication mentioned above) to 5GC for PCC (i.e., the first rule mentioned above) determination. In addition, AF can also provide an alternative QoS profile (i.e., the first alternative QoS mentioned above) and an alternative PDU set QoS profile (i.e., the second alternative QoS profile mentioned above). Optionally, AI can also subscribe to notifications of alternative QoS profiles and / or alternative PDU set QoS profiles (i.e., the first event mentioned above), and / or notifications that all alternative profiles cannot be met (the lowest priority alternative QoS profile and the alternative PDU set QoS profile cannot be met) (i.e., the second event mentioned above).

[0624] Optionally, the flexibility indication of the PDU and PDU set QoS processing may indicate at least one of the following options:

[0625] Enable flexibility in PDU and PDU Set QoS processing (i.e. enabling the first function mentioned above), i.e. alternative QoS profiles or alternative PDU Set QoS profiles can override each other based on indications or operator policies / local configurations.

[0626] The alternative PDU set QoS profile will overwrite (i.e., replace) the alternative QoS profile;

[0627] The alternative QoS profile will override the alternative PDU set QoS profile;

[0628] Alternative QoS Profiles or Alternative PDU Set QoS Profiles may override each other based on the priority of the related profiles.

[0629] Optionally, in addition to providing flexibility indications for PDU and PDU set QoS processing, alternative QoS profiles, alternative PDU set QoS profiles, QoS references or separate QoS parameters, AF can also provide corresponding priorities for alternative QoS profiles and alternative PDU set QoS profiles (i.e., the third information and fourth information mentioned above).

[0630] Optionally, for the alternative QoS profile and the alternative PDU set QoS profile, when the AF provides the QoS references of the alternative QoS profile and the alternative PDU set QoS profile to the network, the one or more QoS references are arranged in a priority order. When the AF provides the individual QoS parameters of the alternative QoS profile and the alternative PDU set QoS profile to the network, the QoS parameters of the one or more alternative PDUs and PDU sets are arranged in a priority order.

[0631] Each requested Alternative QoS Profile and Alternative PDU Set QoS Profile includes the following individual parameters:

[0632] Packet delay budget,

[0633] Packet Error Rate,

[0634] Packet delay budget,

[0635] Packet error rate,

[0636] PSIHI,

[0637] UL certificate bit rate,

[0638] DL guaranteed bit rate,

[0639] Averaging window,

[0640] Maximum data burst,

[0641] Indicates the flexibility of PDU and PDU set QoS processing.

[0642] Optionally, the AF session resource request may also carry XRM service information, identifying the XRM service data flow or data flow group (e.g., multi-modal service ID), UE address / UE identifier, AF identifier application ID, flow description, DNN, S-NSSAI, QoS parameters, protocol description characteristics (including media type, forward error correction coding usage, encryption description, multi-flow connection QoS requirements), and other corresponding information. Here, the multi-modal service ID can be used to identify all flows in the XRM service group.

[0643] 2. The NEF authorizes the AF request. If the AF is untrusted, the NEF sends the AF request to the PCF. Optionally, the NEF performs relevant mappings, including mapping the XRM service identifier (AF-Service-Identifier) ​​to the DNN and S-NSSAI, mapping external applications to CN application identifiers, and mapping external UE identifiers to CN internal UE identifiers (such as SUPI) based on the UDM profile. It also performs mapping of external to internal XRM service group identifiers based on the UDM profile.

[0644] 3. Based on the parameters provided by the AF, the NEF determines whether to call the TSCTSF to send the parameters to the PCF or to send the parameters directly to the PCF. The PCF receives the attributes provided by the AF (ie, the information provided by the AF in step 1 above) from the NEF or TSCTSF.

[0645] NEF triggers Npcf_PolicyAuthorization_Create request and sends AF session resource request to PCF, carrying indication and QoS requirement information for PCF policy decision (ie, the information provided by AF in step 1 above).

[0646] 4. PCF determines PCC rules.

[0647] Optionally, the PCF may determine that updated or new policy information (ie, PCC rules) needs to be sent to the SMF.

[0648] Optionally, the PCF may determine a PCC rule based on the flexibility indication of the PDU and PDU set QoS processing, and send the PCC rule to the SMF. The PCC rule may carry the flexibility indication of the PDU and PDU set QoS processing.

[0649] Optionally, the PCF may determine the alternative QoS profile and the alternative PDU set QoS profile of the PCC rule based on the QoS reference parameters or QoS parameter sets in the alternative QoS profile and the alternative PDU set QoS profile in the AF request.

[0650] Optionally, the PCF may arrange the determined alternative QoS profiles and alternative PDU set QoS profiles in the same priority order indicated by the AF based on the flexibility indication of the PDU and PDU set QoS processing and include them in the PCC rules and send them to the SMF.

[0651] Optionally, the PCF can enable QoS notification control, notifying the PCF when the access network device's transmission resources cannot meet the QoS requirements of any QoS profile, or when the access network device's QoS profile is overwritten.

[0652] 5. The PCF responds with Npcf_Policy Authorization_Create response to the NEF.

[0653] 6.NEF sends Nnef_AFsessionWithQoS_Create response message to AF.

[0654] 7. PCF initiates Npcf_SMPolicyControl_UpdateNotify request to SMF.

[0655] Optionally, the Npcf_SMPolicyControl_UpdateNotify request includes PCC rules.

[0656] Optionally, when the SMF receives the PCC rule, the SMF can determine the QoS rule (i.e., the second rule mentioned above) based on the PCC rule to configure / activate the rule to the UPF (e.g., via the N4 session).

[0657] Optionally, the SMF shall provide flexibility indication of PDU and PDU Set QoS treatment to the NG-RAN to indicate QoS implementation.

[0658] Optionally, the SMF derives the QoS parameters of the QoS flow based on PCC rule information in the PCC rule bound to the QoS flow.

[0659] Optionally, if the PCC rule contains alternative QoS profiles and alternative PDU set QoS profiles, the SMF shall also prioritize the alternative QoS profiles and alternative PDU set QoS profiles. Furthermore, the SMF shall provide the priority list of the alternative QoS profiles and alternative PDU set QoS profiles to the NG-RAN.

[0660] 8.SMF replies Npcf_SMPolicyControl_UpdateNotify response to PCF.

[0661] 9.SMF can trigger the PDU session modification process and provide QoS rules to NG-RAN.

[0662] Optionally, if the SMF provides the NG-RAN with a new priority list of alternative QoS profiles and alternative PDU Set QoS profiles, the NG-RAN shall replace the previously stored priority list of alternative QoS profiles and alternative PDU Set QoS profiles with it.

[0663] Optionally, when the QoS requirements of the current QoS profile cannot be met, the NG-RAN will consider the flexibility indication of the PDU and PDU set QoS processing to select an alternative QoS profile whose QoS requirements can be met.

[0664] 10. If PDU set-related notification control is configured for the QoS flow, when the (R)AN (i.e., the aforementioned access network device) determines that the PDU set QoS target of the QoS flow cannot be met or can be met again, the (R)AN sends an N2 message (including PDU session ID, N2SM information) to the SMF.

[0665] Optionally, the N2 information includes the QFI and an indication that the QoS target of the QoS flow cannot be met or can be met again, respectively. In this case, the N2 information is equivalent to the above-mentioned first message. Optionally, when the QoS target corresponding to the PDU QoS profile, PDU set QoS profile, alternative QoS profile, or alternative PDU set QoS profile cannot be achieved, the N2 information indicates that the QoS target corresponding to the PDU QoS profile, PDU set QoS profile, alternative QoS profile, or alternative PDU set QoS profile cannot be met. In this case, the N2 information is equivalent to the above-mentioned second message.

[0666] Optionally, the (R)AN may send an N2 message to the AMF, after which the AMF calls Nsmf_PDU session_UpdateSMContext to send the N2 message to the SMF.

[0667] 11. If PCF subscribes to the event, SMF will report the event to PCF.

[0668] Optionally, the event may be, for example: the QoS target of the QoS flow cannot be met or can be met again, or the QoS targets corresponding to the PDU QoS profile, PDU set QoS profile, alternative QoS profile, and alternative PDU set QoS profile cannot be met.

[0669] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network function node, etc.) in any of the above methods.

[0670] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD).

All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

[0671] In the embodiments of the present disclosure, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of the hardware circuit. The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and implementing the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
