In this embodiment, a service range supported by a network slice resource (in this embodiment, the network slice resource refers to a network slice management function NSMF) is reported by the network slice resource to a communication service management function CSMF that is connected with the network slice resource in a broadcast manner, and similarly, the communication service management function CSMF records a reported service coverage range supported by the network slice resource. The service coverage supported by the network slice resources is ambiguous, if the network slice resources belong to provincial operators, the default is administrative provinces, and if the network slice resources belong to third parties, the general coverage can be roughly reported or the default is valid nationwide; the received network slice ordering information of the user comprises a network slice coverage range, a proper network slice resource is selected according to the network slice coverage range, a plurality of network slice resources are selected from all network slice resources which are in interface connection with the CSMF according to a scheduling rule of the network slice coverage range to form a network slice resource set A1, in addition, it needs to be noted that not all network slice resources can support providing service coverage range, the network slice resources can be attributed to an alternative network slice resource set B1, wherein the priority of the network slice resource set A1 is greater than that of the alternative network slice resource set B1.
In this embodiment, the network slice resource set screened in step 201 includes a plurality of network slice resources, at this time, a network slice resource meeting the user requirement needs to be screened from the network slice resource set by using the network slice template information, when a network slice resource meeting the user requirement exists in the network slice resource set, step 203 is executed, and when no network slice resource meeting the user requirement exists in the network slice resource set, step 207 is executed.
In this embodiment, the CSMF, a communication service management function, stores therein network slice template information synchronized with network slice resources, and the CSMF may mark the source of the network slice template information, and further, there may be a scenario where a plurality of network slice resources synchronize with the same network slice template information (mainly, slice types in the network slice template information are the same, network KPIs are the same, and parameter constraints may be different) to the CSMF; when user network slice ordering information is received, comparing network slice template information in the network slice ordering information with network slice template information of network slice resources in a network slice resource set stored in the CSMF, further screening network slice resources corresponding to the network slice template information meeting user requirements from the network slice resource set to form a network slice resource subset, if no network slice template information is adapted to the network slice ordering information, defaulting all network slice resources in the network slice resource set to be valid, taking the network slice resource set A0 and the alternative network slice resource set B0 screened in step 201 as an example, when there are network slice resources meeting user requirements in the sets A1 and B1, respectively forming the network slice resources meeting user requirements into a network slice resource subset a11 and an alternative network slice resource subset B11, and respectively forming the rest network slice resources in the sets A1 and B1 into sets a12 and B12, wherein priorities of the sets a11, B11, a12 and B12 are: a11 is greater than B11 is greater than A12 is greater than B12.
In this embodiment, the network slice subset selected in step 203 includes a plurality of network slice resources, at this time, a network slice resource meeting the user requirement needs to be selected from the network slice resource set by using the network slice cost, before the network slice resource is selected, it needs to first determine whether the network slice resource in the network slice resource subset includes information of the network slice cost, when the network slice resource in the network slice resource subset includes the network slice cost, step 205 is executed, and when the network slice resource in the network slice resource subset does not include the network slice cost, step 207 is executed.

In this embodiment, when the effective network slice resource set obtained in step 205 is not empty, slice creation requests are sequentially sent to the network slice resources from low to high according to the cost price of each network slice resource in the effective network slice resource set, so as to allow the network slice resources to create a network slice service, when a network slice resource returns that the creation of the network slice service is successful, no slice creation request is sent to other network slice resources, and when the effective network slice resource set obtained in step 205 is empty, step 207 is executed.
In the present embodiment, a network slice resource set actually refers to three types of sets: a network slice resource set, a network slice resource subset and an effective network slice resource set, wherein the network slice resources which do not meet the user requirements in the three sets are transmitted into a scheduling set according to the priority, then a slice creation request is sent to the network slice resources in the scheduling set according to a preset scheduling strategy, the network slice resources which can create network slice services according to the user requirements are searched for the network slice resources to create the network slice services, when the network slice resources return to the network slice services and are successfully created, the slice creation requests are not sent to other network slice resources, wherein the scheduling strategy comprises a polling mechanism, a broadcast mode and a latest and oldest non-scheduling mode, the polling mechanism is to adopt a request mode one by one aiming at the selected scheduling set (the scheduling set comprises a plurality of network slice resources and is arranged according to the priority), when the first returned network slice service is successfully created, the polling is terminated, the broadcast mode refers to initiating a request to all network slice resources aiming at the selected scheduling set (the scheduling set comprises a plurality of network slice resources and is arranged according to priority), selecting the network slice resource which is successfully created by the earliest returned network slice service, the mode mainly aims at the slice which does not need to detect the network capability by default, the latest non-scheduled mode refers to scheduling aiming at the selected scheduling set (the scheduling set comprises a plurality of network slice resources and is arranged according to priority) according to the longest sequencing of the latest non-scheduled time, the scheduling is terminated when the first returned network slice service is successfully created, and the scheduling mode is used for ensuring the network slice resources with overlapped service coverage, the service can be distributed to each network slice resource in a balanced manner as much as possible.
Compared with the prior art, the method and the device for creating the network slice service have the advantages that on the basis of achieving the beneficial effects brought by the first implementation mode, the network slice resource set meeting the requirements of the user can be screened out step by step according to the requirements of the user, then the creation request is sent to the network slice resources in sequence according to the priority, the creation of the network slice service is completed, and when the network slice resources meeting the requirements of the user cannot be screened out, the creation request is sent to the network slice resources according to the scheduling strategy, the creation of the network slice service is completed, so that the technical scheme provided by the embodiment of the invention can efficiently and accurately create the network slice service.

In this embodiment, although all the network slice resources in the effective network slice resource set screened in step 301 meet the user requirement, a plurality of network slice resources in communication with the communication service management function CSMF are not all capable of creating the network slice service, when the network slice resources in the effective network slice resource set support creation of the network slice service, step 303 is executed, and when none of the network slice resources in the effective network slice resource set support creation of the network slice service, step 304 is executed.
Step 303, sending a slice creation request to a network slice resource in the effective network slice resource set, so that the network slice resource creates a network slice service.
In this embodiment, slice creation requests are sequentially sent to the network slice resources from low to high according to the cost price of each network slice resource in the effective network slice resource set, so that the network slice resources create network slice services, and when a network slice resource returns that the network slice service is successfully created, no slice creation request is sent to other network slice resources.
And step 304, selecting the network slice resource with the lowest network slice cost, returning the network slice resource to the user, receiving a secondary ordering request of the user, and creating a network slice service according to the secondary ordering request, wherein the secondary ordering request comprises a newly-created identifier.
In this embodiment, when none of the network slice resources in the effective network slice resource set supports creation of the network slice service, but there is a network slice resource that can create the network slice service and the network slice cost, the network slice resource with the lowest network slice cost is selected as the designated network slice resource, and the network slice cost is returned to the user, if the user accepts the construction quotation, the user will first receive a new network slice product request initiated by the user, the communication service management function CSMF dispatches the new network slice product request to the designated relevant department unit, so as to assign the relevant department unit to newly create the network slice cost, and generate a new dispatch identifier, when the communication service management function CSMF receives a new completion message, the user is notified to initiate a secondary subscription, after the communication service management function CSMF receives the user's secondary subscription message, the new dispatch identifier is carried in the secondary subscription message, the communication service management function CSMF finds the designated network slice resource creation of the network slice service according to the new dispatch identifier, wherein, the receiving single unit is not necessarily supported by the system, so the communication service management function f does not support communication of the communication platform and the sms message dispatch mode.
Compared with the prior art, the embodiment of the invention can effectively complete the creation of the network slice service meeting the requirements of the user by returning the network slice resource with the lowest cost price to the user and receiving the secondary order message of the user after the user recreates the slice product to complete the creation of the network slice service meeting the requirements of the user on the basis of realizing the beneficial effects brought by the first embodiment, thereby improving the use experience of the user.
