Abstract
Various embodiments provide RU/DU/CU chaining in an O-RAN by ZTP operations automatically. The chaining creates a logical gNB for achieving flexibility in the O-RAN. In some embodiments, one or more RUs are chained to a DU in a cell site when the DU is initiated in the O-RAN. In those embodiments, a network management system is employed to store and manage O-RAN configurations to facilitate the RU/DU/CU chaining. In some embodiments, the cell site is customized during the chaining process.
Claims18
A method for chaining a radio unit and distribution unit automatically in an open radio access network (O-RAN), the method being implemented by a computer system, wherein the method comprises:
- detecting a distribution unit (DU) is instantiated in the O-RAN;
- obtaining chaining information for the DU, the chaining information indicating a chaining between the DU and at least one radio unit (RU);
- resetting the at least one RU;
- and
- chaining the DU with the at least one RU to form a radio access network (RAN) for a cell site.
A computer system configured to execute a method for chaining a radio unit and distribution unit automatically in an open radio access network (O-RAN), wherein when the method is executed, the computer system is caused to perform:
- detecting a distribution unit (DU) is instantiated in the O-RAN;
- obtaining chaining information for the DU, the chaining information indicating a chaining between the DU and at least one radio unit (RU);
- resetting the at least one RU;
- and
- chaining the DU with the at least one RU to form a radio access network (RAN) 11 for a cell site.
