[0056] The technical solutions in the embodiments of the present disclosure will be described in detail below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present disclosure.

[0057] In the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0058] The terms "first", "second", "third", etc. are used only for descriptive purposes and are not to be construed as implying or implying relative importance or an indication of the number of indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0059] Referring to FIG. 1, a flowchart of a method for processing quality of service information is provided. The method for processing quality of service information is performed by a first network element, and includes the following steps S11:

[0060] S11, the first network element acquires a first service flow and quality of service information of the first service flow.

[0061] Further, the method further includes step S12:

[0062] S12, the first network element determines the association relationship between the quality of service information and the service flow description of the first service flow according to the quality of service information and the first service flow.

[0063] Preferably, the first network element is one or more of an AF network element, an NEF (Network Exposure Function) network element, a PCF (Policy Control Function) network element, a UPF (User Plane Function) network element, or a SMF (Session Management Function) network element.

[0064] The quality of service information includes one or more of the following information: quality of service indication 5QI information, delay, packet loss rate, jitter, average rate, maximum rate, minimum rate, and average buffer length.

[0065] It should be noted that, taking the first network element as an AF network element as an example, in the related art, for the AF network element, the 5QI acquired / requested by the AF network element is a standard 5QI or a preconfigured 5QI, but the AF cannot dynamically perceive the correspondence between the service flow description and the 5QI, for example, a PCF (Policy Control Function) allocates a new quality of service information for a service flow requested by the AF network element according to a dynamic PCC rule (Policy and Charging Control rule), and the AF network element cannot perceive it, resulting in that the 5QI on the AF side is not enough to represent the service flow information requested or subscribed by the AF network element. It can be seen that the AF network element in the existing related art cannot dynamically acquire the association relationship between the 5QI and the service flow description, and therefore cannot perform flexible scheduling processing in view of the service level granularity.

[0066] In order to solve the above problems, the disclosure provides a processing method of quality of service information, the first network element acquires a specific first service flow and quality of service information corresponding to the first service flow, and determines an association relationship between the quality of service information and the service flow description according to the quality of service information and the service flow description of the first service flow.

[0067] As a preferred implementation, after step S12, the method further includes step S13:

[0068] S13, the first network element locally stores the association relationship between the quality of service information and the service flow description.

[0069] Further, after determining the association relationship between the quality of service information and the service flow description, the first network element retains or stores the association relationship between the quality of service information and the service flow description in the local memory, so as to perform flexible scheduling processing on the service level granularity according to the association relationship between the quality of service information and the service flow description.

[0070] As a preferred implementation, after step S12, the method further includes step S14:

[0071] S14, the first network element sends the quality of service information and the first service flow, and / or a flow identifier including the quality of service information and the first service flow, to a second network element.

[0072] Further, after determining the association relationship between the quality of service information and the service flow description, the first network element can also send the association relationship between the quality of service information and the service flow description to a second network element related to the service flow, so that the second network element can also perform flexible scheduling processing on the service level granularity according to the association relationship between the quality of service information and the service flow description.

[0073] The first network element sends the association relationship in the following manner: sequentially sending the service quality information and the first service flow to the second network element, and / or sending a flow identifier comprising the service quality information and the first service flow to the second network element, where the flow identifier represents the association relationship.

[0074] It should be noted that the second network element is a NWDAF network element or a network element for analyzing and processing service quality information, and the first network element and the second network element are different.

[0075] By using the technical means of the embodiments of the present disclosure, the first network element can dynamically obtain and process the association relationship between the service quality information and the service flow description, thereby being able to make flexible scheduling processing at the service level granularity, effectively improving the service perception ability of the 5G network and enhancing the network industry integration capability.

[0076] As a preferred implementation, the embodiments of the present disclosure are further implemented on the basis of any of the above embodiments. Referring to FIG. 2, which is a first principle schematic diagram of a service quality information processing method in the embodiments of the present disclosure, the embodiments of the present disclosure propose a first scheme of the service quality information processing method. Among them, the first network element is one or more of an application function (AF) network element, an NEF network element, a PCF network element, a UPF network element, or an SMF network element, and the second network element is a network data analysis function (NWDAF) network element or a network element for analyzing and processing service quality information. The embodiments of the present disclosure further optimize and explain the service quality information processing process in the application scenario where the first network element is an AF network element and the second network element is a NWDAF network element.

[0077] Then, step S11, that is, the first network element obtains the service quality information of the first service flow, comprises at least one of the following flows:

[0078] The first network element requests or subscribes the service quality information corresponding to the first service flow from a third network element;

[0079] And / or,

[0080] The first network element obtains the service quality information in the identifier of the first service flow;

[0081] And / or,

[0082] The first network element obtains the service quality information corresponding to the first service flow requested or subscribed by a fourth network element from a third network element.

[0083] Preferably, the third network element is an NEF network element, a PCF network element, a UPF network element, or an SMF network element. The third network element is different from the first network element.

[0084] Preferably, the fourth network element is a NEF network element, a PCF network element, a UPF network element, or a SMF network element. The fourth network element is different from the third network element.

[0085] In the embodiments of the present disclosure, the first scheme is that the AF network element requests or subscribes the quality of service information of the first service flow from the third network element (5GC network element), and sends the quality of service information and the service flow description (or APP ID) to the NWDAF network element, and / or the flow identifier including the quality of service information and the service flow description.

[0086] Of course, the first network element can also directly obtain the quality of service information of the first service flow from the identifier of the first service flow; the first network element can also obtain the quality of service information requested or subscribed by the fourth network element from the third network element through implicit subscription, which will not be described here.

[0087] Preferably, the first network element requests or subscribes the quality of service information corresponding to the first service flow from the third network element, including:

[0088] In the process of the first network element processing one or more of the subscription process, the quality of service information request process, and the quality of service information update process, the first network element requests or subscribes the quality of service information of the first service flow from the third network element.

[0089] That is, the AF network element initiates a request or subscription to the third network element in one or more of the following processes: (1) AF subscription process; (2) AF QoS request process; (3) AF QoS update process, to request or subscribe to the quality of service information corresponding to its own service flow.

[0090] It should be noted that the AF subscription process refers to the process of the AF network element subscribing to related messages from other network elements, the AF QoS request process refers to the process of the AF network element requesting to check the quality of service QoS information of related services, and the AF QoS update process refers to the process of the AF network element updating the quality of service QoS information of related services. The AF subscription process, the QoS request process, and the QoS update process can refer to the existing related technologies, which will not be described here.

[0091] Preferably, step S14, that is, the first network element sends the quality of service information and the first service flow, and / or the flow identifier including the quality of service information and the first service flow to the second network element, including:

[0092] In the process of one or more of the subscription procedure, the request procedure, and the quality of service information analysis procedure of the second network element, the first network element sends the quality of service information and the first service flow, and / or a flow identifier comprising the quality of service information and the first service flow, to the second network element.

[0093] That is, the AF network element sends the determined association between the quality of service information and the service flow description to the NWDAF network element in one or more of the following processes: (1) a subscription procedure of the NWDAF; (2) a request procedure of the NWDAF; and (3) a sustainable analysis procedure of the QoS.

[0094] It should be noted that the subscription procedure of the NWDAF refers to a process in which the NWDAF network element subscribes to relevant messages from other network elements, the request procedure of the NWDAF refers to a process in which the NWDAF network element requests relevant messages from other network elements, and the sustainable analysis procedure of the QoS refers to a process in which an NF consumer (such as the AF) requests / or subscribes to analysis information of the sustainability of the QoS from the NWDAF. The subscription procedure, the request procedure, and the sustainable analysis procedure of the NWDAF can refer to existing related technologies, and thus will not be described herein.

[0095] More preferably, before the first network element sends the quality of service information and the first service flow, and / or a flow identifier comprising the quality of service information and the first service flow, to the second network element, the method further comprises one or more of the following:

[0096] The first network element determines the second network element according to information of the first service flow.

[0097] Specifically, before the AF network element sends the association between the quality of service information and the service flow description to the NWDAF network element, the AF network element first determines a sending object, that is, addresses the NWDAF network element. When the AF addresses the NWDAF, the AF can address the corresponding NWDAF network element according to service belonging relationship, user binding relationship, a location where the service occurs, and an operator contract, etc. After the AF network element addresses the NWDAF network element, the AF sends the association between the quality of service information and the service flow description to the NWDAF network element in the above-mentioned process of the NWDAF network element.

[0098] Optionally, the addressing method can comprise: addressing by means of an operator contract, NRF service discovery, a mapping relationship between the service and the NWDAF, etc.

[0099] By adopting the technical means of the embodiments of the present disclosure, when the first network element is one or more of an AF network element, an NEF network element, a PCF network element, a UPF network element, or an SMF network element, and the second network element is an NWDAF network element, the first network element acquires service quality information of a service flow from a third network element, and generates an association between the service quality information and a service flow description for local storage and / or sending to the NWDAF network element, so that the AF and the NWDAF network element can dynamically acquire and process the association between the service quality information and the service flow description, thereby being able to make flexible scheduling processing facing the service level granularity, effectively improving the service perception ability of the 5G network and enhancing the network convergence ability.

[0100] As a preferred implementation, the embodiments of the present disclosure further provide another service quality information processing method, executed by a second network element, comprising the following steps S21:

[0101] S21, the second network element acquires a first service flow and service quality information of the first service flow.

[0102] Further, the method further comprises the following step S22:

[0103] S22, the second network element determines an association between service quality information and service flow description according to the service quality information and the service flow.

[0104] Preferably, the second network element is an NWDAF network element.

[0105] The service quality information comprises one or more of the following information: service quality indication 5QI information, delay, packet loss rate, jitter, average rate, maximum rate, minimum rate, and average buffer duration.

[0106] It should be noted that, taking the second network element as an NWDAF network element as an example, in the related art, for the NWDAF network element, the NWDAF network element acquires QoS information of a service flow such as 5QI from a 5G core network element (5GC network element) according to a request or subscription of a consumer NF (Network Function), such as an AF network element, but the NWDAF does not locally retain and perceive the binding relationship between the service flow description and the 5QI, resulting in that the NWDAF network element cannot dynamically correct or improve the behavior of the NF. For example, the AF network element requests the NWDAF network element for sustainability analysis of a certain 5QI, the NWDAF network element analyzes that it is an XRM service and also corresponds to other service quality information, and can report all analysis results corresponding to the 5QI to the AF network element. It can be seen that the AF, NWDAF, and other network elements in the existing related art cannot dynamically acquire the association between the 5QI and the service flow description, and therefore cannot make flexible scheduling processing facing the service level granularity.

[0107] To solve the above problems, the embodiments of the present disclosure provide a service quality information processing method, wherein a second network element acquires specific first service flow and service quality information corresponding to the first service flow, and determines the association between the service quality information and the service flow description according to the service quality information and the service flow description of the first service flow.

[0108] As a preferred implementation, after step S22, the method further comprises step S23:

[0109] S23, the second network element locally stores the association between the service quality information and the service flow description.

[0110] As a preferred implementation, after step S22, the method further comprises step S24:

[0111] S24, the second network element sends the service quality information and the first service flow, and / or a flow identifier comprising the service quality information and the first service flow, to the first network element.

[0112] Further, after determining the association between the service quality information and the service flow description, the second network element can also send the association between the service quality information and the service flow description to the first network element related to the service flow, so that the first network element can also flexibly schedule and process the service level granularity according to the association between the service quality information and the service flow description.

[0113] The second network element sends the association in the following manner: sequentially sends the service quality information and the first service flow to the first network element, and / or sends a flow identifier comprising the service quality information and the first service flow to the first network element, and the flow identifier represents the association.

[0114] Preferably, the first network element is one or more of an AF network element, an NEF network element, a PCF network element, a UPF network element, or an SMF network element.

[0115] As a preferred implementation, the embodiments of the present disclosure are further implemented on the basis of any of the above embodiments. Referring to FIG. 3, which is a second principle schematic diagram of the service quality information processing method in the embodiments of the present disclosure, the embodiments of the present disclosure provide a second scheme of the service quality information processing method. The second network element is a NWDAF network element, and the second network element is one or more of an AF network element, an NEF network element, a PCF network element, a UPF network element, or an SMF network element. The embodiments of the present disclosure further optimize and explain the service quality information processing process in the application scenario where the second network element is a NWDAF network element and the first network element is an AF network element.

[0116] Then, the second network element acquires the first service flow and the quality of service information of the first service flow in step S21.

[0117] After the first network element sends the first service flow request to the third network element, the second network element requests or subscribes the first service flow and the quality of service information corresponding to the first service flow from the third network element.

[0118] Preferably, the third network element is an NEF network element, a PCF network element, a UPF network element, or an SMF network element.

[0119] In the second scheme, after the AF network element initiates the first service flow request to the third network element, the third network element generates the quality of service information corresponding to the first service flow, and the NWDAF network element subscribes or requests the first service flow and the corresponding quality of service information from the third network element, and sends the quality of service information and the service flow description (or APP ID) to the AF network element, and / or the flow identifier including the quality of service information and the service flow description.

[0120] Preferably, in step S24, the second network element sends the quality of service information and the first service flow, and / or the flow identifier including the quality of service information and the first service flow to the first network element, including:

[0121] In the process of the first network element subscribing or requesting from the second network element, the second network element sends the quality of service information and the first service flow, and / or the flow identifier including the quality of service information and the first service flow to the first network element by means of notification or request response.

[0122] Specifically, the NWDAF network element requests or subscribes the quality of service information from the third network element, and the third network element responds or reports the service flow information and the corresponding quality of service information in one or more of the following processes: (1) AF QoS request process; (2) AF QoS update process.

[0123] The NWDAF network element sends the determined association between the quality of service information and the service flow description to the AF network element in one or more of the following processes: (1) AF subscription process; (2) AF request process.

[0124] It should be noted that the AF subscription process refers to the process of the AF network element subscribing to related messages from other network elements, and the AF request process refers to the process of the AF network element requesting related messages from other network elements. The AF subscription process and the request process can refer to the existing related technology, and will not be described here.

[0125] More preferably, before the second network element sends the service quality information and the first service flow, and / or a flow identifier comprising the service quality information and the first service flow, to the first network element, the method further comprises:

[0126] The second network element determines the corresponding first network element according to the information of the first service flow requested by the first network element.

[0127] Specifically, the NWDAF network element first determines the sending object, that is, addresses the AF network element, before sending the association relationship between the service quality information and the service flow description to the AF network element. When addressing the AF network element, the NWDAF network element can address the AF network element according to the service belonging relationship, the operator subscription, or other service flow information, or acquire the AF information from the NEF. After addressing the AF network element, the NWDAF network element sends the association relationship between the service quality information and the service flow description to the AF network element in the above processing flow of the AF network element.

[0128] By using the technical means of the embodiments of the present disclosure, when the first network element is one or more of an AF network element, an NEF network element, a PCF network element, a UPF network element, or an SMF network element, and the second network element is a NWDAF network element, the service flow request is sent to the 5GC network element through the AF network element, the NWDAF network element acquires the service quality information of the service flow from the 5GC network element, and generates the association relationship between the service quality information and the service flow description for local storage and / or sending to the AF network element, so that the AF and the NWDAF network element can both dynamically acquire and process the association relationship between the service quality information and the service flow description, thereby being able to face the service level granularity for flexible scheduling processing, effectively improving the service perception ability of the 5G network and enhancing the network convergence ability.

[0129] As a preferred embodiment, the embodiments of the present disclosure are further implemented on the basis of any of the above embodiments.
