Method and system for managing radio unit (ru) supervision failure in o-ran

A method for managing Open Radio Unit (O-RU) (116) supervision failure through a plurality of NETCONF (Network Configuration Protocol) clients by a management-plane (M-Plane) in an open radio access network (ORAN) (100) comprising:

• upgrading the established M-Plane between the O-RU (116) and the plurality of NETCONF clients available with each of an Open Distributed Unit (O-DU) (114) and a Service Management and Orchestration (SMO) framework (102), wherein management function of the M-Plane includes software management, fault management, configuration management, performance management and file management;
• detecting supervision failure by the plurality of NETCONF clients in the connection between the O-RU (116) and the plurality of NETCONF clients within a session at a predefined time duration, the session is accompanied by an exchange of messages, wherein the O-DU (114) and the SMO framework (102) manage the O-RU (116) in the M-Plane using NETCONF, wherein the O-DU (114) and the SMO framework (102) each corresponds to a NETCONF client while the O-RU (116) corresponds to a NETCONF server;
• and
• switching the connection from a hybrid model to a hierarchical model in case of the failure with the hybrid model, whereby switching the connection ensures returning to the hybrid model without reset when connection of the SMO framework is back, thereby saving a prior implemented security configuration in the O-RU (116),
• wherein, in connection of the hierarchical model a NETCONF client is configured to network with the O-DU (114) and the O-DU (114) manages the NETCONF server and in connection of the hybrid model, the O-RU (116) is managed by the plurality of NETCONF clients each corresponding to the O-DU (114) and the SMO framework (102);
• and SMO Client interfaces with the O-DU and the O-RU both.
