technical field

Embodiments of the present invention relate to the field of computers, and in particular, to a network slice management method, apparatus, network device, and storage medium.

Background technique

Currently, the management functions for network slices include: Communication Service Management Function (CSMF) and Network Slice Management Function (NSMF), etc. For a scenario in which a communication service management function CSMF communicates with multiple network slice management functions NSMF, when receiving a slice creation request, the following operations will be performed: The communication service management function CSMF receives the first network slice management function NSMF and returns that slices are not supported. During creation, the communication service management function CSMF can repeatedly modify the slice parameters, and then "negotiate" with the first NSMF to ensure that the slice is successfully created; or the communication service management function CSMF receives the unsupported slice returned by the first network slice management function NSMF. When created, the communication service management function CSMF can communicate with other network slice management functions NSMF until the slice is successfully created.

However, for the business scenario where CSMF communicates with multiple NSMFs, CSMF repeatedly establishes communication with NSMF to confirm that NSMF can create slices, and by default, all NSMF services connected to CSMF are interoperable, and can be Coordinate with all NSMFs to ensure communication service requirements. In fact, since the construction and operation of NSMFs can belong to different operators or third parties, the coverage of services supported by NSMFs connected to the same CSMF may not necessarily overlap, which will lead to the occurrence of conflicts between CSMF and NSMF. Many invalid interface communications are established between them, and the selection of NSMF will be inaccurate, resulting in low network slice creation efficiency and creation accuracy.

Detailed ways

In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art can appreciate that, in the various embodiments of the present invention, many technical details are set forth in order for the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can be realized. The following divisions of the various embodiments are for the convenience of description, and should not constitute any limitation on the specific implementation of the present invention, and the various embodiments may be combined with each other and referred to each other on the premise of not contradicting each other.

The first embodiment of the present invention relates to a network slice management method, which is applied in the communication service management function CSMF, as shown in FIG. 1 , and specifically includes:

Step 101: Receive network slice order information, where the network slice order information includes network slice coverage, network slice template information, and network slice cost.

In this embodiment, the communication service management function CSMF provides the user with a human-machine interface, and receives the user's network slice order information. The network slice order information includes network slice coverage, network slice template information, and network slice cost. The network slice coverage is Determined by the user through the Geographic Information System (GIS) module in the provided man-machine interface, the user can directly select the coverage area of the slice network on the map (determine a polygon area by multiple points); network slice template Information (Network SliceTemplate, NST) is to select slice products through the provided man-machine interface. The selection of slice products is equivalent to determining the slice type, and then fill in the Service Level Agreement (SLA), network key The network slice template information actually includes information such as slice type, SLA, and network KPI. Among them, network slice types include enhanced mobile broadband (eMBB), ultra-reliable and low For ultra-reliable low latency communications (URLLC) and massive internet of things (MIoT), network KPIs vary according to the type of network slice. For example, eMBB needs to pay attention to the uplink/downlink rate, capacity, etc., URLLC It is necessary to focus on the delay, etc. The network KPI can be a specific value or a value constraint; the cost of network slicing is also obtained through the human-machine interface, that is, the cost of applying the network slicing template to the network element. , in addition to the above three kinds of information, users can also select the validity period of the sliced network according to their needs on the human-machine interface provided by CSMF. , the user needs to unsubscribe through the human-machine interface provided by CSMF, and the network slicing will be released. Among them, the slicing product selected by the user in the human-machine The network slice template information NST synchronized by the slice management function (NSMF) realizes the design and addition of network slice products, encapsulates existing network capabilities into user-oriented slice products, and synchronizes network slices in network slice resources (network slice management function NSMF). The template information is sent to the communication service management function CSMF. The core parameters of the network slice template information include slice type, SLA, network KPIs and constraints, and NST identifiers. For the network slice template information that has been synchronized to the communication service management function CSMF, if the slice capability parameters and Constraints change, network slice resources ( The network slice management function (NSMF) synchronizes the updated network slice template information to the communication service management function CSMF, and the communication service management function CSMF confirms whether the network slice template information is a new template or an existing template according to the NST identifier, so as to decide whether to add or update. , the communication service management function CSMF can query all NST information through the NST identifier.

Step 102: Obtain a valid network slice resource set according to the network slice coverage, network slice template information and network slice cost, and send a slice creation request to the network slice resources in the valid network slice resource set, so that the network slice resource can create a network slice service .

In this embodiment, the communication service management function CSMF will communicate with a plurality of network slice resources, the network slice resources refer to the network slice management function NSMF that supports the creation of network slice services, and the communication service management function CSMF will Slice coverage, network slice template information, and network slice cost Filter out an effective network slice resource set that meets the user's needs from multiple network slice resources, and then follow the priority of each network slice resource in the effective network slice resource set. Send a slice creation request to a network slice resource for the network slice resource to create a network slice service. When a network slice resource returns that the network slice service is successfully created, the slice creation request will not be sent to other network slice resources.

Step 103, associate the network slicing service with the preset charging combination.

In this embodiment, after the network slicing service is successfully created, it will be associated with a preset charging combination according to the characteristics of the network slicing service. As shown in FIG. 2 , one charging combination includes at least one charging combination. For example, if a slicing product that is billed by area is ordered at the beginning of the month, the operator wants to order the slicing service fee for the current month, and then charge the service fee for two years on a monthly basis. Two billing rules need to be combined to complete the billing requirements. , that is: the first combination of area (billing dimension) and one-time charging (billing frequency) and one-time charging (billing time point) and no validity period (validity period) when effective, and by area (counting frequency) A combination of billing dimension) and monthly (billing frequency) and monthly specified date billing (billing time point) and number of months (validity period), wherein the billing rules mentioned in this application include the billing dimension , billing frequency, billing time point, and validity period. When the network slice service fails to be associated with the preset billing combination, it is considered that the user has not selected the billing combination for the network slicing service. The manual order review process is triggered during network slicing, and operators can select a billing combination for the network slicing service during the order review process.

Step 104, adding the network slicing service to the operator system to complete the management of the network slicing service.

In this embodiment, after the network slicing service is successfully created, the communication service management module CSMF will provide the user with a man-machine interface, where the user can access the network slicing service to the user equipment UE or withdraw the network slicing service from the user equipment UE, The CSMF then adds the network slicing service and the corresponding user equipment information (to be accessed or to be withdrawn into the operator system, so that the operator system can manage the network slicing service.

Compared with the prior art, in the embodiment of the present invention, the communication service management function is receiving network slice order information, wherein the network slice order information includes network slice coverage, network slice template information, and network slice cost. , network slicing template information, and network slicing cost to obtain a set of valid network slicing resources, and send a slice creation request to the network slicing resources in the set of valid network slicing resources, so that the network slicing resources can create network slicing services, and the network slicing services and presets Charge combination association; add network slicing services to the operator system to complete the management of network slicing services. Therefore, the creation and management of network slice services can be completed efficiently and accurately according to the user's network slice order information, which solves the problems caused by the establishment of many invalid interface communications between CSMF and NSMF and the inaccurate selection of NSMF in the prior art. The problem of low efficiency and low accuracy of network slice creation and management.

The second embodiment of the present invention relates to a network slice management method, which is basically the same as the network slice management method provided by the first embodiment of the present invention, and the difference lies in that the set of valid network slice resources obtained in step 102 is refined. The steps, as shown in Figure 3, include:

Step 201: Acquire a network slice resource set according to the network slice coverage.

In this embodiment, the service scope supported by the network slice resource (in this embodiment, the network slice resource refers to the network slice management function NSMF) is reported by the network slice resource to the connected communication service management function CSMF in a broadcast manner, Similarly, the communication service management function CSMF will record the service coverage supported by the reported network slice resources. If the service coverage supported by network slicing resources is unclear, if it is a network slicing resource belonging to a provincial operator, it can default to the administrative province; if it is a network slicing resource belonging to a third party, it can roughly report the general coverage or The default is valid nationwide; the received user's network slice order information will include the network slice coverage, select the appropriate network slice resources according to the network slice coverage, according to the scheduling rule of the network slice coverage, will connect with CSMF from the Multiple network slicing resources are selected from all network slicing resources in the network slicing resource to form a network slicing resource set A1. In addition, it should be noted that not all network slicing resources can support providing service coverage. This type of network slicing resources can be classified as The candidate network slice resource set B1, wherein the network slice resource set A1 has a higher priority than the candidate network slice resource set B1.

Step 202: Determine whether there is a network slice resource matching the network slice template information in the network slice resource set.

In this embodiment, the network slicing resource set selected in step 201 includes multiple network slicing resources. In this case, the network slicing template information needs to be used to filter the network slicing resources that meet the user's needs from the network slicing resource set. When there are network slicing resources that meet user requirements in the resource set, step 203 is performed, and when there are no network slicing resources that meet user requirements in the network slicing resource set, step 207 is performed.

Step 203: Acquire a network slice resource subset from the network slice resource collection according to the network slice template information.

In this embodiment, the communication service management function CSMF stores the network slice template information synchronized by the network slice resources, and the CSMF will mark the source of the network slice template information. In addition, there will be multiple network slice resources synchronized to the CSMF. The same network slice template information (mainly refers to the scenario where the slice types in the network slice template information are the same, the network KPIs are the same, and the parameter constraints can be different); when the user network slice order information is received, the network slice order information in the network slice The slice template information is compared with the network slice template information of the network slice resources in the network slice resource collection stored in the CSMF, and the network slice resource corresponding to the network slice template information that meets the user's needs can be further screened from the network slice resource collection. , which is used to form a sub-set of network slice resources. If there is no adapted network slice template information in the network slice order information, all network slice resources in the default network slice resource collection are valid. Resource set A0 and candidate network slicing resource set B0 are taken as an example. When there are network slicing resources that meet user requirements in sets A1 and B1, the network slicing resources that meet user requirements constitute network slicing resource subset A11 and alternative network respectively. The slice resource sub-set B11 consists of the remaining network slice resources in the sets A1 and B1 to form sets A12 and B12 respectively, wherein the priorities of sets A11, B11, A12 and B12 are: A11 is greater than B11 and A12 is greater than B12.

Step 204: Determine whether the network slicing resources in the network slicing resource subset include network slicing costs.

In this embodiment, the network slice subset screened in step 203 includes multiple network slice resources. In this case, the network slice cost needs to be used to filter out network slice resources that meet user requirements from the network slice resource collection. Before resources, it is necessary to first determine whether the network slice resources in the network slice resource subset include network slice cost information. When the network slice resources in the network slice resource subset include network slice costs, perform step 205, when the network slice resource If the network slice resources in the subset do not include network slice costs, step 207 is executed.

Step 205: Acquire a valid network slice resource set from the network slice resource subset according to the network slice cost.

In this embodiment, the network slice order information obtained by the communication service management module CSMF includes the cost price of the network slice, and the cost price of the network slice refers to the cost price of the network slice module applied to the network element, and the network slice resources stored in the CSMF The network slicing template information of the network slicing resources in the sub-set also includes the cost price of the network slicing. The cost price of the two network slicing is compared, and the effective network slicing resource set that meets the user's needs is selected from the network slicing resource sub-collection. The network slicing resource subset A11 and the candidate network slicing resource subset B11 screened in step 203 are taken as an example, and the network slicing resources in the sets A11 and B11 that meet the user's needs constitute an effective network slicing resource set A21 and an effective network slicing resource, respectively. In the set B21, the remaining network slice resources in the sets A11 and B11 are respectively formed into sets A22 and B22, wherein the priorities of the sets A21, B21, A22 and B22 are: A21 is greater than B21 and A222 is greater than B22.

Step 206: Send a slice creation request to the network slice resources in the valid network slice resource set, so that the network slice resources can create network slice services.

In this embodiment, when the set of valid network slicing resources obtained in step 205 is not empty, the network slicing resources are allocated to the network slicing resources in descending order according to the cost price of each network slicing resource in the set of valid network slicing resources. Send a slice creation request for the network slice resource to create a network slice service. When a network slice resource returns that the network slice service is successfully created, it will no longer send a slice creation request to other network slice resources. When the valid network slice obtained in step 205 If the slice resource set is an empty set, step 207 is executed.

Step 207: Send a slice creation request to the network slice resources in the network slice resource set according to the preset scheduling policy, so that the network slice resources can create a network slice service, wherein the scheduling policy includes a polling mechanism, a broadcast mode, and the most recently unscheduled mode .

In this embodiment, the network slicing resource set actually refers to three types of sets: a network slicing resource set, a network slicing resource sub-set and an effective network slicing resource set. Enter the scheduling set according to its priority, and then send a slice creation request to the network slicing resources in the scheduling set according to the preset scheduling policy, and find network slicing resources that can create network slicing services according to user needs, so that the network slicing resources can create the network. For slice services, when a network slice resource returns that the network slice service is successfully created, it will no longer send a slice creation request to other network slice resources. The scheduling policies include the polling mechanism, the broadcast mode, and the most recently unscheduled mode. The polling mechanism It refers to the selected scheduling set (the scheduling set contains multiple network slice resources and is arranged by priority), and adopts the one-by-one request mode. When the first returned network slice service is successfully created, the polling is terminated, and the broadcast mode is used. It refers to the selected scheduling set (the scheduling set contains multiple network slicing resources and is arranged by priority), initiates a request to all network slicing resources, and selects the earliest network slicing resource that returns the successful creation of the network slicing service. This mode is mainly: For slices that do not require manual detection of network capabilities by default, the most recently unscheduled mode refers to the selected scheduling set (the scheduling set contains multiple network slice resources and is arranged by priority), according to the longest unscheduled time recently. Scheduling is performed according to the order of the network slicing service, and the scheduling is terminated when the first returned network slicing service is successfully created. This scheduling mode is to ensure that the network slice resources with overlapping service coverage are distributed to each network as much as possible in a balanced manner. Slice resources.

Compared with the prior art, on the basis of realizing the beneficial effects brought by the first embodiment, the embodiment of the present invention can gradually filter out the set of network slice resources that meet the user's needs according to the user's needs, and then sequentially according to the priority Send a creation request to the network slicing resource to complete the creation of the network slicing service, and when the network slicing resource that meets the user's needs cannot be screened out, it will send a creation request to the network slicing resource according to the scheduling policy to complete the creation of the network slicing service, so that this The technical solutions provided by the embodiments of the invention can create network slicing services with high efficiency and high accuracy. Further, because the scheduling policy provided by the present invention includes three types: polling The technical solutions provided by the embodiments can be aimed at different application scenarios and different users, and can better meet the different needs of different users in different application scenarios, thereby improving the user experience.

The third embodiment of the present invention relates to a network slice management method, which is basically the same as the network slice management method provided in the first embodiment, with the difference that, as shown in FIG. 4 , step 102 includes:

Step 301: Obtain an effective network slice resource set according to the network slice coverage, network slice template information and network slice cost.

In this embodiment, the communication service management function CSMF will communicate with a plurality of network slice resources, the network slice resources refer to the network slice management function NSMF that supports the creation of network slice services, and the communication service management function CSMF will Slice coverage, network slice template information and network slice cost filter out an effective network slice resource set that meets user needs from multiple network slice resources.

Step 302: Determine whether all the network slice resources in the valid network slice resource set support the creation of network slice services.

In this embodiment, although the network slicing resources in the effective network slicing resource set screened in step 301 all meet user requirements, not all network slicing resources communicated with the communication service management function CSMF can create network slices service, when the network slicing resources in the valid network slicing resource set support the creation of network slicing services, execute step 303, and when none of the network slicing resources in the valid network slicing resource set support creating network slicing services, execute step 304.

Step 303: Send a slice creation request to the network slice resources in the valid network slice resource set, so that the network slice resources can create a network slice service.

In this embodiment, according to the cost price of each network slice resource in the effective network slice resource set, a slice creation request is sent to the network slice resource in order from low to high, so that the network slice resource can create a network slice service. When the slice resource returns that the network slice service is successfully created, it will no longer send slice creation requests to other network slice resources.

Step 304: Select the network slicing resource with the lowest network slicing cost and return it to the user, receive the user's second order request, and create a network slicing service according to the second order request, wherein the second order request includes a new identifier.

In this embodiment, when none of the network slicing resources in the set of valid network slicing resources support the creation of network slicing services, but there are network slicing resources that can create network slicing services and network slicing costs, the network with the lowest network slicing cost is selected. The slice resource is used as the designated network slice resource, and the network slice cost is returned to the user. If the user accepts the construction quotation, it will first receive the request for a new network slice product initiated by the user, and the communication service management function CSMF will dispatch the request for the new network slice product. Go to the designated relevant department for the cost of creating a new network slice for the designated relevant department, and generate a new identifier. When the communication service management function CSMF receives the new creation completion message, it notifies the user to initiate a second order, and the communication service management function CSMF receives the user. After the secondary ordering message is sent, the secondary ordering message carries a newly created identifier, and the communication service management function CSMF searches for the specified network slice resource according to the newly created identifier to create a network slice service. Communication service management function CSMF dispatch form is not limited to platform interface communication, but also supports email and SMS notification methods.

Compared with the prior art, the embodiment of the present invention, on the basis of realizing the beneficial effects brought by the first embodiment, can effectively return all network slice resources in the network slice resource set when the network slice service fails to create the network slice service by returning the lowest value to the user. Network slicing resources at cost price, after re-creating slicing products for users, receive the user's secondary order message to complete the creation of network slicing services that meet user needs, so that the technical solutions provided by the embodiments of the present invention can be more flexible to meet users' needs The demand for network slicing services improves the user experience.

The fourth embodiment of the present invention relates to a network slice management method, which is basically the same as the network slice management method provided by the first embodiment, the difference is that, as shown in FIG. 5 , before step 103, it further includes:

Step 401: Provide a man-machine interface to an operator to obtain a charging combination, wherein the charging combination includes at least one charging rule, and the charging rule includes charging dimension, charging frequency, charging time point and service validity period.

In this embodiment, the communication service management function CSMF will provide an operator with a man-machine interface for the operator to set a charging combination. The charging combination set by the operator is shown in FIG. 2 . At least one charging rule. The charging rule mentioned in this application includes elements such as charging dimension, charging frequency, charging time point, and validity period. As shown in Figure 6, the charging dimension and charging frequency can be Free combination, charging frequency and charging time point are conditional combination, charging time point and validity period are also conditional combination, in which, each network slice service that needs to be charged can include multiple charging rules to complete the calculation. fee combination.

The billing dimension includes four methods: billing based on network slice coverage, billing based on the number of network slice user equipment (User Equipment, UE) accesses, billing based on network slicing performance and service requirement levels, and overall billing. Charging by network slice coverage refers to charging slice service fees based on the coverage area. When creating a network slice, the user needs to draw the coverage area of the slice network on the man-machine interface map provided by CSMF. Step-by-step billing is performed, that is, the area in which the area falls is charged according to the level; billing based on the number of user equipment accesses in the network slice refers to charging based on the number of user equipment connected to the network slice; according to the performance and service requirements of the network slice Graded charging refers to quantifying some core parameter indicators of network slices according to the present invention and charging by steps. For example, for eMBB type slices, assuming that the above/downlink rate is used as the charging dimension, it is divided into multiple parts according to the value range of the uplink/downlink rate. Each charging interval is charged according to the steps; the overall charging refers to the cost of applying the slice to the network element as a reference, and the overall package pricing in operation. This charging model is suitable for network slices created for a short-term activity.

The billing frequency includes four frequency modes: one-time billing, daily billing, monthly billing, and annual billing; among them, one-time billing means that billing is only charged once within the billing validity period, and billing is done on a daily basis It means billing once a day at a designated time within the billing validity period, monthly billing means billing once a month on a specified date within the billing validity period, and annual billing means billing once a year on a specified date within the billing validity period.

There are four types of billing time points: one-time billing when the order takes effect, daily billing at a specified time, monthly billing on a specified date, and annual billing on a specified day. Billing. Orders are not limited to the concept of ordering orders for sliced products. They can be understood as any ordering behavior that generates billing. Daily billing at specified time means that the billing time is used in conjunction with the "daily" billing frequency. The specific time point of daily billing, and the monthly specified date billing means that the provided billing time point selection method is the day of the month or the penultimate day of the month, or the specified date and specific billing time, the billing time It is used in conjunction with the "monthly" billing frequency, specifying a certain day and time of each month for billing, and billing on a specified date every year means selecting a specified month and a date to provide the day of the month, the penultimate day of the month, or the specified date. There are three options for the date and select the specified time. This billing time is used in conjunction with the "yearly" billing frequency, specifying a certain month, a certain day and a certain time of the year for billing.

The validity period refers to the type of billing validity period. The specific value of the validity period comes from the billing validity period provided by the order or the validity period set by the sliced product. If there is no validity period in the subscription information, the user needs to cancel the subscription to stop the billing. On day/month/year, unless there is an external cancellation to prompt the order to have a validity period, the billing behavior will always exist. The specified date means that the billing behavior has existed until the specified date, and the number of days refers to the billing within the specified number of days after the order takes effect. If the behavior exists, it should be used in conjunction with the "daily specified time billing" billing time point. The number of months refers to the existence of the billing behavior within the specified number of months after the order takes effect; it should be used in conjunction with the "monthly specified time billing" billing time point. , the number of years refers to the existence of billing behavior within the specified number of years after the order takes effect. It is used in conjunction with the billing time point of "billing at specified time every year".
