In LTE, there is no control node that collects Performance Management (PM) data from base stations, like a Base Station Controller (BSC) or Radio Network Controller (RNC) does for 2G/3G systems. Instead, an Operating Support System (OSS) has to collect PM data directly from eNodeBs, thereby causing scalability issues. A method of improved PM for LTE networks uses the statistical counters defined in the eNodeB and counters created from elementary events and parameters of events. Specific counters or user-defined counters can be defined that are, for example, not traditionally implemented in the nodes, or that use events from additional Network Elements (NEs). The counter files and events are collected by an observation gateway or directly by the PM application, and are monitored in different time scales. The counters are also aggregated for different time periods, thereby providing scalability and time-based statistics for the counter values.
