Method and system of collecting topology and inventory data in open radio access network

A non-transitory computer readable medium configured to store instructions thereon for causing a system to execute a method comprising:

• receiving a request through an interface of a service management and orchestrator (SMO), wherein the request contains instructions for topology and inventory information to be collected, created or updated;
• transferring the request to a topology and inventory (TE&IV) management module;
• collecting, creating or updating topology and inventory data for at least a first component of the network based on the request, wherein the topology and inventory data includes:
• a relationship information between the first component and at least a second component of the network, and
• capability information for the first component.

A system for collecting, creating, or updating topology and inventory data for a network, the system comprising:

• a service management and orchestrator (SMO) configured to:
• receive a request through an interface, wherein the request contains a topology and inventory information to be collected, created or updated;
• transfer the request to a topology and inventory (TE&IV) management module;
• collect, create or update topology and inventory data for at least a first component of the network based on the query, wherein the topology and inventory data includes:
• a relationship information between the first component and at least a second component of the network, and
• capability information for the first components;
• and
• output the collected topology and inventory data through the interface.
