Self-establishment of new RAN NE in network describes the procedure of a new NG-RAN NE can automatically establish when it is powered up and connect to the IP network in multi-vendor scenario, which includes:
– Network Configuration data handling
– Plug and connect to management system
4.2.2 Network configuration data handling
Network configuration data handling makes the network configuration data available to the management system support self-configuration process, which may include network configuration data preparation, network configuration data transfer and network configuration data validation. This happens except all of the network configuration data for NE can be generated by the management system supporting self-configuration process.
Network configuration data preparation: This makes the network configuration data ready in operator’s network management system who provides the network configuration data. How to prepare the network configuration data in operator’s network management system is out of scope of the present document.
Network configuration data transfer: This transfers the Network configuration data from network configuration data Provider to the network configuration data Consumer.
Network configuration data validation: This validates the syntax and semantics of network configuration data. It takes place in the network configuration data Consumer.
4.2.3 Plug and connect to management system
Plug and connect to management system connects the NE to its management system providing support for self-configuration process as automatically as possible. The concepts and requirements of plug and connect are specified in TS 28.314 .
Self-configuration puts the NE into a state to be ready to carry traffic in an automated manner. Self-configuration includes following functionality: create self-configuration task, monitor self-configuration process, generate configuration data if needed, download and activate software, download and active configuration data, perform self-test and update network resource model, etc.
