[0128] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0129] The embodiment of the present application provides a digital twin network construction method and a network element, so as to solve the problem of how to apply the digital twin to mobile network services.
[0130] Referring to Figure 1 , Figure 1 is one of flowcharts of the digital twin network construction method provided by the embodiment of the present application, and is used for a first network element, such as Figure 1 As shown in the figure, the method comprises the following steps:
[0131] Step 101, a target query request corresponding to a target creation request is sent to a second network element, the target creation request being used for requesting to create a digital twin network function management object corresponding to a target network element.
[0132] The first network element can be a digital twin network management function (DTN_MF). The second network element can be a network function management function (NFMF), or can be a network slice management function (NSMF), or can be a network slice subnet management function (NSSMF), etc., and the embodiment is not limited thereto.
[0133] In addition, the target query request can comprise but is not limited to a network element identifier of the target network element and a network slice identifier corresponding to the network element identifier.
[0134] Step 102, a query result corresponding to the target query request sent by the second network element is received.
[0135] The query result can be used for modeling the target network element, so that the digital twin network function management object can be created, and the digital twin corresponding to the target network element is realized.
[0136] In one embodiment, the second network element is the NSMF, the NSMF receives the target query request corresponding to the target creation request sent by the DTN_MF; and the DTN_MF receives the query result corresponding to the target query request sent by the NSMF.
[0137] In one embodiment, the second network element is the NSSMF, the NSSMF receives the target query request corresponding to the target creation request sent by the DTN_MF through the NSMF; and the DTN_MF receives the query result corresponding to the target query request sent by the NSSMF through the NSMF.
[0138] In an implementation form, the second network element is an NFMF, the NFMF receives a target query request corresponding to the target creation request sent by the DTN_MF through the NSMF and the NSSMF, and the DTN_MF receives a query result corresponding to the target query request sent by the NFMF through the NSMF and the NSSMF.
[0139] In addition, after the second network element receives the target query request corresponding to the target creation request sent by the first network element, the second network element 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, so that the first network element can create the digital twin network function management object based on the query result.
[0140] It should be noted that the second network element obtaining the query result corresponding to the target query request can include: sending the target query request to a third network element, and receiving the query result corresponding to the target query request sent by the third network element; or querying network element information based on the target query request, and obtaining the query result corresponding to the target query request. The third network element can be another network element other than the second network element and the first network element. The third network element can be used to query network element information, or the third network element can be used to transfer the target query request.
[0141] Step 103, creating the digital twin network function management object based on the query result, the configuration information of the digital twin network function management object matching the configuration information of the target network element.
[0142] The configuration information of the digital twin network function management object matching the configuration information of the target network element can be that 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 implemented by the configuration information of the digital twin network function management object is the same as the function implemented by the configuration information of the target network element. The digital twin network function management object can be a virtual 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 to realize the digital twin corresponding to the target network element.
[0143] In an implementation form, the creating the digital twin network function management object can include creating a digital twin network function MOI. The DTN_MF can perform network information physical modeling and network function modeling to realize the creation of the digital twin network function MOI.
[0144] Regarding the implementation of network information physical modeling:
[0145] (1) The data warehouse-data collection function of the DTN_MF collects the current resource allocation and / or usage of the network, and stores the network configuration, including but not limited to the service profile, the network slice profile, and the MOI configuration information of each network function. The MOI corresponding to the network function is configured to the digital twin corresponding to the network element in the network mapping-function mapping module of the DTN_MF, and the QoS and other policies are issued to the digital twin through the network policy mapping module of the DTN_MF;
[0146] (2) The data warehouse-data collection function of the DTN_MF triggers the performance guarantee and fault management service, and can subscribe to the PA service and / or the FS service, so that the digital twin network can report the current network running state information in real time or at regular intervals and store it.
[0147] Regarding the implementation of network function modeling:
[0148] The DTN_MF can construct a business scenario for a specific twin network logic. Taking network performance monitoring as an example, network threshold control information and operation and maintenance strategies are set in the digital twin for a specific session, for example, the monitoring index name, reporting period, threshold value, trigger condition, threshold adjustment parameter, etc. are set for a specific session, so that network performance monitoring can be realized according to the digital twin.
[0149] In addition, the embodiment of the present application introduces a digital twin in the network system, which can simulate the running environment and running state of the whole end-to-end network, and there is real-time interaction between the digital twin and the network entity. Various running information of the network entity can be input to the digital twin in real time to construct a digital twin network service. The constructed digital twin network is interconnected with the network management system, and the corresponding related network services and network element configurations in the physical entity can be issued to each network element in the digital twin network, and the original network resource model can be used.
[0150] It should be noted that, with the explosive growth of the number of access devices and the number and diversity of operating services in the network, the 5G network will be networked in the form of network slices. The diversified slice services have brought great challenges to the overall network operation and network resource management. The embodiment of the present application introduces digital twin technology in the mobile network field, which can evaluate the availability of the current network before network deployment and implementation, and make early resource use prediction and network deployment state prediction.
[0151] In the embodiment of the application, a target query request corresponding to a target creation request is sent to a second network element, the target creation request is used to request to create a digital twin network function management object corresponding to a target network element; a query result corresponding to the target query request sent by the second network element is received; and the digital twin network function management object is created based on the query result, and configuration information of the digital twin network function management object matches configuration information of the target network element.

The target network element can be one or more network elements. By carrying the network element identifier of the target network element and the network slice identifier corresponding to the network element identifier in the target query request, the first network element can obtain information of a target network element management object, so as to create a digital twin network function management object.
