Method of and An Operating Support System for Providing Performance Management in a Mobile Telecommunications System

摘要

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.

1. A method of system performance management by an Operating Support System (OSS) of a mobile telecommunications system, the mobile telecommunications system comprising a plurality of nodes and radio access units servicing a plurality of cells generating a plurality of operational events data and counter values measured periodically for a first Result Output Period (ROP) the method comprising:
collecting events data and counter values originating from the nodes and radio access units, the events data corresponding to events; aggregating the collected counter values periodically for a second ROP and further ROP; wherein the first ROP, second ROP, and further ROP correspond to a specific operational event and counter; wherein the second and further ROPs have a duration longer than the first ROP; creating further counter values from the collected events data periodically for the second and further ROPs; processing the aggregated and further counter values; analyzing the processed counter values for providing system operational performance indicia in different time scales.
