Referring to fig. 1, fig. 1 is one of flowcharts of a digital twin network construction method provided by an embodiment of the present invention, for a first network element, as shown in fig. 1, the method includes the following steps:
Wherein the first network element may be a digital twin network management function (Digital Twin Network Management Function, dtn_mf). The second network element may be a network function management function (Network Function Management Function, NFMF), or may be a network slice management function (Network Slice Management Function, NSMF), or may be a sub-network slice management function (Network Slice Subnet Management Function, NSSMF), etc., which is not limited in this embodiment.
In addition, the target query request may include, but is not limited to, a network element identifier of a target network element and a network slice identifier corresponding to the network element identifier.
The query result can be used for modeling the target network element, so that a digital twin network function management object can be created, and a digital twin body corresponding to the target network element is realized.
In one embodiment, the second network element is an NSMF, and the NSMF receives a target query request corresponding to the target creation request sent by the dtn_mf; and receiving a query result corresponding to the target query request sent by NSMF by the DTN_MF.
In one embodiment, the second network element is NSSMF, and the NSSMF receives a target query request corresponding to a target creation request sent by the dtn_mf through the NSMF; and receiving a query result corresponding to the target query request sent by NSSMF through NSMF by the DTN_MF.
In one embodiment, the second network element is an NFMF, and the NFMF receives a target query request corresponding to a target creation request sent by the dtn_mf through the NSMF and the NSSMF; and receiving a query result corresponding to the target query request sent by the NFMF through NSMF and NSSMF by the DTN_MF.
In addition, after receiving a target query request corresponding to a target creation request sent by a first network element, a second network element may obtain a query result corresponding to the target query request, and send the query result corresponding to the target query request to the first network element, so that the first network element may create the digital twin network function management object based on the query result.
It should be noted that, the obtaining, by the second network element, the query result corresponding to the target query request may include: the target query request is sent to a third network element, and a query result corresponding to the target query request sent by the third network element is received; or inquiring network element information based on the target inquiry request, and acquiring an inquiry result corresponding to the target inquiry request. The third network element may be other network elements than the second network element and the first network element.

And step 103, creating the digital twin network function management object based on the query result, wherein the configuration information of the digital twin network function management object is matched with the configuration information of the target network element.
The configuration information of the digital twin network function management object is matched with the configuration information of the target network element, or the configuration information of the digital twin network function management object is the same as the configuration information of the target network element, or the function realized by the configuration information of the digital twin network function management object is the same as the function realized by the configuration information of the target network element. The digital twin network function management object can be a virtualized object of the target network element, and the target network element can be modeled based on the query result, so that the digital twin network function management object can be created, and the digital twin corresponding to the target network element is realized.
In one embodiment, the creating the digital twin network function management object may include creating a digital twin network function MOI. Dtn_mf may be physically modeled with network information and network functions to enable creation of digital twin network functions MOI.
