Abstract

Claims (23)

1. A method for analyzing or optimizing a cellular mobile telecommunications network, the method comprising the steps of:

providing of first data being indicative of a first telecommunication traffic condition for at least one of the cells of the telecommunications network,

providing of second data being indicative of location information of the at least one of the cells,

providing of third data being indicative of location information of mobile telecommunication devices within the at least one of the cells,

determining a distribution of a telecommunication traffic condition within the at least one of the cells based on the first, second and third data,

determining fourth data being indicative of a number of handovers occurring at a cell boundary based on motion information derived from the third data,

displaying the distribution of the telecommunication traffic condition and number of handovers occurring at a cell boundary, and

deleting the at least one of the cells if the distribution of the telecommunication traffic condition determines low traffic within the at least one of the cells.

2. The method of claim 1 , the first data comprising at least one of integrated telecommunication traffic within the cell, mean channel occupation time of telecommunication links to or from the cell, average call duration of incoming or outgoing calls, and indicator or traffic values at during a particular time period.

3. The method of claim 1 , the second information being provided by performing a database access to a database storing cell location or shape information of the telecommunications network.

4. The method of claim 1 , the third data being obtained by at least one of cell ID in combination with round trip time measurements, triangulation, and satellite positioning.

5. The method of claim 1 further comprising:

inputting of cell information via a graphical user interface for modifying the telecommunications network,

simulating the distribution of the telecommunication traffic condition or handovers at cell boundaries for the modified telecommunication network based on the first, second and third data.

6. The method of claim 5 , the simulation being performed by means of a traffic model having been established based on the first, second and third data.

7. An operation and maintenance center for a cellular mobile telecommunications network comprising:

means for providing of first data being indicative of a first telecommunication traffic condition for at least one of the cells of the telecommunications network,

means for providing of second data being indicative of location information of the at least one of the cells,

means for providing of third data being indicative of location information of mobile telecommunication devices within the at least one of the cells,

means for determining a distribution of a telecommunications traffic condition within the at least one of the cells based on the first, second and third data,

means for determining fourth data being indicative of a number of handovers occurring at a cell boundary based on motion information derived from the third data,

means for displaying the distribution of the telecommunication traffic condition and number of handovers occurring at a cell boundary, and

means for deleting the at least one of the cells if the distribution of the telecommunication traffic condition determines low traffic within the at least one of the cells.
