Before introducing the embodiment of the present invention, a data acquisition and feedback architecture of a network data analysis function (NWDAF) device defined by 3GPP and a functional entity included in the NWDAF device are introduced. Specifically, referring to fig. 1, functional entities included in the NWDAF data acquisition and feedback architecture specifically include: an NWDAF device, an Application Function (AF) device, an OAM (operation and administration) device, a Network Function (NF) device, and a Unified Database (UDR) device. The AF device is a functional entity for the butt joint of a third-party service provider and an operator network, and one instantiated AF device corresponds to one third-party service provider. The OAM device is a network management function entity, and is used to complete the operation, management and maintenance of the network, including analyzing, predicting, planning and configuring the network and its services, testing and fault management, etc. The NF device may specifically be any instantiated functional entity in the 5G core network Control plane functional entity, such as an Access and Mobility Management Function (AMF) device (not shown in fig. 1), a Session Management Function (SMF) device (not shown in fig. 1), a Policy Control Function (PCF) device (not shown in fig. 1), and so on. The UDR device is a data storage functional entity, and may be used to store subscription data, policy data, application data, and the like of a user.
At present, the design and arrangement of network slices are provided by an operator, and the operator is not responsible for providing specific services, so the operator adapts the network slice resource requirements of the services by presetting one or more fixed templates containing operator network capability evaluation standards, in an actual situation, because different services usually have large or small differences in the network slice resource requirements, the specific services provided by different service providers may have different network capability evaluation standards, if the network slice resources are allocated to each specific service only through the fixed sets of network capability evaluation standards provided by the operator side, the flexibility is poor, the actual network slice resource requirements of the specific services are often not matched with the network slice resources allocated to the specific services, and the network slice resource utilization rate is low.
Based on the existing problems, an embodiment of the present invention provides a method for scheduling network slice resources, which is shown in fig. 2 and includes the following steps:
step S210: and the NWDAF device receives a target service evaluation information request which is sent by the AF device and carries the target service evaluation information.
Specifically, the target service evaluation information is carried in a target service evaluation information request sent by the target AF device in advance. The 5G core network comprises a plurality of instantiated AF devices, and the target AF device is any one of the plurality of instantiated AF devices in the 5G core network.
In a specific implementation, referring to fig. 3, a process of the NWDAF apparatus acquiring the target service evaluation information from the target AF apparatus may include the following steps:
step S310: and the AF device sends a target service evaluation information request carrying the target service evaluation information.
Step S320: and the NWDAF device receives a target service evaluation information request which is sent by the AF device and carries the target service evaluation information.
Step S330: and the NWDAF device stores the target service evaluation information carried in the target service evaluation information request to the local.
Further, when the target service evaluation information in the target AF device is changed, in order to enable the NWDAF device to acquire the changed target service evaluation information in time, the following steps may be further performed:
step S340: the NWDAF device transmits a target service evaluation information change subscription request to the target AF device.
Specifically, the target service evaluation information subscription request is used for subscribing a change notification event of the target service evaluation information in the target AF apparatus to the target AF apparatus. The change notification event includes: when a change event of the target service evaluation information occurs in the target AF device, the target AF device sends the changed target service evaluation information to the NWDAF device so as to instruct the NWDAF device to update the target service evaluation information stored in the local to the changed target service evaluation information.
Step S350: the NWDAF device receives the subscription confirmation message sent by the target AF device.
Specifically, the NWDAF device receives a subscription confirmation message sent by the target AF device to the NWDAF device in order to inform the NWDAF device that the change notification event subscription was successful.
Specifically, the target service evaluation information may include at least: target traffic evaluation rules, and network slice identification of the target network slice. The target network slice and the network slice identifier of the target network slice may refer to the corresponding description in step S210, and are not described herein again. The target service evaluation rule, that is, the evaluation rule of the network capability made by the service provider for a specific service according to the actual situation, includes, but is not limited to: target traffic evaluation rules, and network slice identification of the target network slice. In a specific implementation, the target service evaluation rule may include: the service evaluation calculation rule, the service evaluation score threshold value and the service satisfaction user proportion preset condition, wherein the service evaluation calculation rule can be a service evaluation calculation formula which is made by a service provider according to actual conditions and specific to the service, and is used for calculating the service evaluation score of a single user; the service meeting user proportion preset condition and the service evaluation score threshold can be parameters which are set by a service provider according to actual requirements and determine that the service meets the user and the service meets the user proportion, and the service evaluation score threshold and the service meeting user proportion preset condition are set by the service provider.
In a specific implementation, referring to fig. 4, the usage rule of the NWDAF apparatus on the target service evaluation rule is as follows:
step S410: calculating a service evaluation score of the user to be evaluated according to the service evaluation calculation rule and the network slice service evaluation data of the user to be evaluated; wherein the user to be evaluated is any one of the users.
Step S420: and judging whether the business evaluation score is greater than or equal to a business evaluation score threshold value.
If the judgment result is yes, that is, the service evaluation score is determined to be greater than or equal to the service evaluation score threshold, step S430 is executed; if the determination result is negative, that is, it is determined whether the service evaluation score is smaller than the service evaluation score threshold, step S470 is executed.
Step S430: and determining the user to be evaluated as a target user.
Step S440: and counting the number of target users of the target users, and acquiring the ratio of the number of the target users to the number of access users in the network slice service evaluation data as the service satisfaction user ratio.
Step S450: and judging whether the service meets the user occupation ratio or not.
Specifically, the service satisfaction user occupation ratio preset condition may be set by the service provider according to an actual situation, for example, the service satisfaction user occupation ratio is greater than or equal to a service satisfaction user occupation ratio preset threshold; or the service satisfaction user occupation ratio falls into the service satisfaction user occupation ratio preset range, and the like.
If the determination result is yes, that is, it is determined that the service satisfies the user occupation ratio and satisfies the service satisfies the user occupation ratio preset condition, the step S460 is executed; if the determination result is negative, that is, it is determined that the service satisfies that the user proportion does not satisfy the service and satisfies the user proportion preset condition, step S470 is executed.
Step S460: determining to send a slice resource scheduling request to the OAM device.
Step S470: it is determined not to send a slice resource scheduling request to the OAM device.
Step S220: the NWDAF device sends a first message carrying request information and a period duration corresponding to a preset period to the network management OAM device every other preset period.
Specifically, the request information may be information for requesting the service performance of the network slice and information for requesting the service performance of the user on the network slice.
The request information for requesting the network slice service performance may include, but is not limited to: network slice identification request information of the target network slice and network slice access user number request information of the target network slice. Specifically, the 5G core network includes a plurality of network slices, and the target network slice is any one of the plurality of network slices. The Network Slice identifier of the target Network Slice may specifically be identification Information capable of identifying the target Network Slice, and in a specific implementation, the Network Slice identifier may be Single-Network Slice selection auxiliary Information (S-NSSAI) of the target Network Slice.
The network slice identification request information is used for requesting the network slice identification of the target network slice, and the network slice access user number request information is used for requesting the number of users accessing the target network slice. The request information for requesting the user service performance of the user on the network slice may include, but is not limited to: user identification request information of the user and user access network slicing time request information. The user identification request information is used for requesting the user identification of the user of the target network slice, and the user access network slice frequency request information is used for requesting the frequency of accessing the target network slice by each user in the users of the target network slice.
The period duration of the preset period may be set by a person skilled in the art according to an actual situation, which is not limited in the embodiment of the present invention. Wherein in one alternative the cycle duration may be 7 days.
Step S230: and the OAM device acquires the network slice service evaluation data in the target time period according to the request information and the period duration.
Specifically, the duration of the target time period is the period duration, and the time end point of the target time period is the time when the first message is received, that is, the time point obtained by subtracting the period duration from the time when the first message is received is the time start point of the target time period.
The network slice service evaluation data, that is, the corresponding data acquired by the OAM device according to the request information, includes, but is not limited to: a network slice identifier of the target network slice acquired according to the network slice identifier request information of the target network slice, an access user number of the access target network slice accumulated in a target time period acquired according to the network slice access user number request information of the target network slice, a user identifier (e.g., a subscription permanent identifier (SUPI) of the user) of the target network slice acquired according to the user identifier request information of the user of the target network slice, and an access number of times of the user accessing the target network slice for each user identifier acquired according to the user access network slice number request information.
