Abstract

This invention relates to monitoring and maintaining a network in telecommunications networks which comprise a large number of network elements. These network elements are presented as a hierarchical diagram or as a map display on a graphical user interface. The graphical user interface presents performance information of the network element as a graphical presentation in connection with the network element symbol in such a way that the operator can, at one glance, identify the network elements that are the most important in terms of operation of the network or the network elements most affected by faults. In accordance with an embodiment of the invention, the alarm situation of each element is displayed as a graphical presentation along with the network element symbol on the graphical user interface simultaneously with the graphical presentation representing the performance. In this manner, fault management FM and performance management PM are connected, whereby a link is provided between the faults and their effects on the telecommunications network or the network element.

Claims

1. A network monitoring method for a telecommunications network which comprises a large number of network elements, the method comprising:

collecting, in a centralized manner, network-element-specific performance information,

calculating a normal performance and a current performance of each network element, and

displaying a graphical presentation for each network element on a graphical user interface, the graphical presentation indicating the current performance of the network element in relation to the normal performance.

2. The method of claim 1, further comprising calculating a normal performance of the network element for each day of the week and/or for several times of the day, and using the normal performance corresponding to the current day of the week and/or the time of the day as said normal performance.

3. The method of claim 1, further comprising collecting, in a centralized manner, alarms coming from the network elements, and presenting the alarms as network-element-specific graphical presentations on the graphical user interface.

4. The method of claim 3, further comprising displaying a graphical presentation representing the performance of each network element simultaneously with the alarms of the respective network element on a digital map on said graphical user interface.
