# Modeling 5G network function

# Model 5G network function {#ariaid-title1}

You can model your 5G network and manage your any type of network functions by using the Telecommunications Network Inventory application. By using the model, you can create, review, update, and delete your networks.

## 5G network model {#modeling_5g_xnf__section_pkw_vhs_qxb}

You must create a business application, an application service, and network interfaces to model your 5G network as shown in the
following
diagram.

* Business Application: The business application table stores all network functions. The business application records the labels of all classes proposed by 3GPP^TM\*^ as a type of managed network function. To learn more, see [Define the network function details](https://servicenow-prod.fluidtopics.net/aydW_PdLpm2oScr3RQ_ztw "Create a network function record in the Telecommunications Network Inventory application. You can manage the network functions such as 5Physical Network Function (PNF), Virtual Network Function (VNF) and so on.").
* Application Service: The application service stores the instance of the corresponding network function, which is associated with the business applications to indicate its type, such as DU or CU-CP and so on. Each instance of a function has a record in the application service. You can create a relationship with a business application and network interface. To learn more, see [Define network service instance details](https://servicenow-prod.fluidtopics.net/jGmeAi1bj0F1seUu29EA4A "Create an application service instance using the Telecommunications Network Inventory application. You can create service instances to model different types of network functions.").
* Network Interface: The network interface stores all the logical IP interfaces that are assigned to the managed network. The logical interfaces represent a peer-to-peer relationship. If there's a connection between a distributed unit (DU) and centralized unit (CU) control plane or user plane (UP) functions, a logical connection is created between the logical interfaces. By using the relationship editor, you can create a relationship with an application service. To learn more, see [Define the network interface details](https://servicenow-prod.fluidtopics.net/OIC_ntQo5klI24LuaLB9fg "Review, update, or create a network instance for a network interface that controls the signaling and management functions between your networks. You define these attributes so that you can track and manage your network instances in the Telecommunications Network Inventory application.") and [CI relationship editor](https://www.servicenow.com/docs/access?context=c_RelationshipEditor&version=australia&pubname=australia-servicenow-platform&ft:locale=en-US) to create or edit a relationship.
{#modeling_5g_xnf__ul_o4p_k35_yxb} \*The 3GPP^TM^ TS28.541 V18.2.2 inspired attributes are provided as the pack tables. To learn more, see [Pack tables](https://servicenow-prod.fluidtopics.net/jwLth4Sb_IS~ydh8kNBf1A "Use pack tables to learn about the tables that help to model your 5G network."). To learn more about attribute packs, see [Attribute packs](https://servicenow-prod.fluidtopics.net/fwEXVnxRRxU7vP8gZHiBBA "Use an attribute pack to capture the attributes that you define against a set of records in a configuration item (CI) in the Telecommunications Network Inventory application. You can capture the additional information about the network asset in the inventory form that belongs to the CI.").
