In the embodiments of the present disclosure, a digital twin network construction method and network elements are proposed to solve the problem of how to apply digital twins to mobile network services in related technologies.

Referring to FIG. 1, FIG. 1 is one of the flowcharts of a digital twin network construction method provided by an embodiment of the present disclosure, which is used for a first network element. As shown in FIG. 1, the method includes the following steps:

Step 101: Send a target query request corresponding to a target creation request to a second network element, where the target creation request is used to request creation of a digital twin network function management object corresponding to the target network element.

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 subnetwork slice management function (Network Slice Subnet Management Function, NSSMF), etc., which are not limited in this embodiment.

In addition, the target query request may include, but not limited to, the network element identifier of the target network element and the network slice identifier corresponding to the network element identifier.

Step 102: Receive a query result corresponding to the target query request sent by the second network element.

Wherein, the query result can be used to model the target network element, so that a digital twin network function management object can be created to realize a digital twin corresponding to the target network element.

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 the DTN_MF receives a query result corresponding to the target query request sent by the NSMF.

In one embodiment, the second network element is an NSSMF, and the NSSMF receives the target query request corresponding to the target creation request sent by the DTN_MF through the NSMF; the DTN_MF receives the query result corresponding to the target query request sent by the NSSMF through the NSMF.

In one embodiment, the second network element is the NFMF, and the NFMF receives the target query request corresponding to the target creation request sent by the DTN_MF through the NSMF and the NSSMF; the DTN_MF receives the query result corresponding to the target query request sent by the NFMF through the NSMF and the NSSMF.

In addition, after the second network element receives the target query request corresponding to the target creation request sent by the first network element, it can obtain the query result corresponding to the target query request, and send the query result corresponding to the target query request to the first network element. A corresponding query result is requested, so that the first network element can create the digital twin network function management object based on the query result.
