Abstract

The present invention relates to a method for analyzing and/or optimizing a cellular mobile telecommunications network and to an operation and maintenance center for a cellular mobile telecommunications network comprising:

means 1 for providing of first data 3 being indicative of a first telecommunication traffic condition for at least one of the cells of the telecommunications network,

means 2 for providing of second data being indicative of location information of the at least one of the cells,

means 4, 5 for providing of third data 6 being indicative of location information of mobile telecommunication devices within the at least one of the cells,

means 7, 8 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.

Claims

1. A method for analyzing and/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.

2. The method of claim 1, the first data comprising one or more of the following indicator values:

integrated telecommunication traffic within the cell, mean channel occupation time of telecommunication links to and/or from the cell, average call duration of incoming and/or outgoing calls, indicator or traffic values at the busy hour.

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

4. The method of claim 1, the third data being provided by means of one or more of the following location determination methods:

cell ID in combination with RTT measurements, triangulation, satellite positioning.

5. The method of claim 1 further comprising determining of fourth data being indicative of handovers occurring at cell boundaries based on motion information derived from the third data.

6. The method of claim 1 further comprising visualization of the distribution of the second telecommunication traffic condition.

7. 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 and/or the handovers at cell boundaries for the modified telecommunication network based on the first, second and third data.

8. The method of claim 7, the simulation being performed by means of a traffic model having been established based on the first, second and third data.

9. A computer program product comprising:

first program means for inputting of first data being indicative of a first telecommunication traffic condition for at least one of the cells of a cellular mobile telecommunications network,

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

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

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

10. 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.
