Method of providing performance management data, corresponding network element and corresponding radio communication system

A network element of a communications network for providing performance management, PM, data to an Operations and Maintenance, OAM, system to which the network element is connected, the PM data being related to one or more objects associated with the network element, the network element comprising:

• processor circuitry configured to:
• determine whether at least one of the one or more objects is an unmirrored object, the unmirrored object being invisible to the OAM system;
• accumulate PM data of the at least one unmirrored object with PM data of further objects associated with the network element responsive to at least one of the one or more objects being an unmirrored object;
• and
• a system interface coupled to the processor circuitry, the system interface configured to provide the accumulated PM data to be transmitted through the system interface to the OAM system,
• wherein the processor circuitry is further configured to accumulate the PM data by accumulating the PM data of all unmirrored objects belonging to the same object class.

A radio communication system comprising:

• a network element configured to:
• determine whether at least one of one or more objects is an unmirrored object, the unmirrored object being invisible to an Operations and Maintenance, OAM, system;
• accumulate PM data of the at least one unmirrored object with PM data of further objects associated with the network element responsive to at least one of the one or more objects being an unmirrored object;
• transmit the accumulated PM data to through a system interface;
• wherein the OAM system is configured to request and maintain the PM data transmitted by the network element;
• and
• wherein the network element is further configured to accumulate the PM data by accumulating the PM data of all unmirrored objects belonging to the same object class.
