Introduction
The BBS approach is to take advantages of the existing ONAP implementation as much as we can. In Nomadic ONT scenario, ONT is logically modeled to PNF. Restconf collector introduced in R3 is reused to collect ONT relocation notification. The notification will be converted into VES pnf registration event by VES Mapper micro service. PRH, which is the generic PNF Registration Handler micro service in ONAP, is enhanced to cover PNF re-registration logic. This newly defined PNF re-registration event triggers Policy engine to take actions over SDNC component to fulfill the ONT relocation procedure.
