Abstract

A method, performed by a non-real-time (NRT) radio access network (RAN) Intelligent Controller (RIC) within a Service Management and Orchestration (SMO) framework of an open-RAN (O-RAN) network, includes obtaining, by the NRT RIC, fault, configuration, accounting, performance and security (FCAPS) related information via an O1 connection from at least one network element (NE) in the O-RAN network, and implementing, by the NRT RIC, at least one first FCAPS related operation corresponding to the FCAPS related information for the at least one NE via the O1 connection, where the O1 connection includes an interface between the at least one NE and an O1 termination of the NRT RIC.

Claims (37)

1 . A method, performed by a non-real-time (NRT) radio access network (RAN) Intelligent Controller (RIC) within a Service Management and Orchestration (SMO) framework of an open-RAN (O-RAN) network, the method comprising:

obtaining, by the NRT RIC, fault, configuration, accounting, performance and security (FCAPS) related information via a connection from at least one network element (NE) in the O-RAN network, and

implementing, by the NRT RIC, at least one first FCAPS related operation corresponding to the FCAPS related information for the at least one NE via the connection,

wherein the connection comprises an interface between the at least one NE and a termination in the NRT RIC within the SMO.

2 . The method of claim 1 , wherein the connection is an O1 connection and the termination is an O1 termination in an NRT RIC framework of the NRT RIC.

3 . The method of claim 1 , further comprising:

obtaining, by the NRT RIC, at least one second FCAPS related operation corresponding to an O-RAN cloud (O-Cloud) function; and

implementing, by the NRT RIC, the at least one second FCAPS related operation corresponding to the O-Cloud function via another connection.

4 . The method of claim 3 , wherein the other connection is an O2 connection that comprises an interface between O-Cloud infrastructure and an O2 termination of the NRT RIC.

5 . The method of claim 4 , wherein the O2 termination is in an NRT RIC framework of the NRT RIC.

6 . The method of claim 1 , wherein the NRT RIC comprises a policy manager configured to implement the at least one first FCAPS related operation.

7 . The method of claim 6 , wherein the NRT RIC comprises an NRT RIC framework separate from the policy manager.

8 . A system implemented in a telecommunications network, the system comprising:

a memory storing instructions; and

a processor configured to execute the instructions to:

obtain, by a non-real-time (NRT) radio access network (RAN) Intelligent Controller (RIC) within a Service Management and Orchestration (SMO) framework of an open-RAN (O-RAN) network, fault, configuration, accounting, performance and security (FCAPS) related information via a connection from at least one network element (NE) connected to the O-RAN network; and

implement, by the NRT RIC, at least one first FCAPS related operation corresponding to the FCAPS related information for the at least one NE via the connection,

wherein the connection comprises an interface between the at least one NE and a termination in the NRT RIC within the SMO.

9 . The system of claim 8 , wherein the connection is an O1 connection and the termination is an O1 termination in an NRT RIC framework of the NRT RIC.

10 . The system of claim 8 , wherein the processor is further configured to execute the instructions to:

obtain, by the NRT RIC, at least one second FCAPS related data corresponding to an O-RAN cloud (O-Cloud) function; and

implement, by the NRT RIC, the at least one second FCAPS related operation corresponding to the O-Cloud function via another connection.

11 . The system of claim 10 , wherein the other connection is an O2 connection that comprises an interface between an O-Cloud infrastructure and an O2 termination of the NRT RIC.

12 . The system of claim 11 , wherein the O2 termination is in an NRT RIC framework of the NRT RIC.

13 . The system of claim 8 , wherein the NRT RIC comprises a policy manager configured to implement the at least one first FCAPS related operation.

14 . The system of claim 13 , wherein the NRT RIC comprises an NRT RIC framework separate from the policy manager.

15 . A non-transitory, computer-readable storage medium storing instructions that, when executed by at least one processor, cause the at least one processor to:

obtain, by a non-real-time (NRT) radio access network (RAN) Intelligent Controller (RIC) within a Service Management and Orchestration (SMO) framework of an open-RAN (O-RAN) network, at least one first fault, configuration, accounting, performance and security (FCAPS) related operation via a connection from at least one network element (NE) in the O-RAN network; and

implement, by the NRT RIC, at least one first FCAPS related operation corresponding to the FCAPS related information for the at least one NE via the connection,

wherein the connection comprises an interface between the at least one NE and a termination in the NRT RIC within the SMO.

16 . The storage medium of claim 15 , wherein the connection is an O1 connection and the termination is an O1 termination in an NRT RIC framework of the NRT RIC.

17 . The storage medium of claim 15 , wherein the instructions, when executed, further cause the at least one processor to:

obtain, by the NRT RIC, at least one second FCAPS related operation corresponding to an O-RAN cloud (O-Cloud) function; and

implement, by the NRT RIC, the at least one second FCAPS related operation corresponding to the O-Cloud function via another connection.

18 . The storage medium of claim 17 , wherein the other connection is an O2 connection that comprises an interface between O-Cloud infrastructure and an O2 termination of the NRT RIC.

19 . The storage medium of claim 18 , wherein the O2 termination is in an NRT RIC framework of the NRT RIC.

20 . The storage medium of claim 15 , wherein the NRT RIC comprises a policy manager configured to implement the at least one first FCAPS related operation.
