METHOD AND SYSTEM FOR REAL TIME CELLULAR NETWORK CONFIGURATION
First Claim
1. A method for configuring a cellular telecommunications network, comprising the steps of:
- collecting measurements of one or more of a plurality of parameters measured at a plurality of mobile stations;
reporting of these measurements to cellular base stations;
forwarding of these measurements from said base stations via an element manager to a remote centralized server;
combining said measurements from one of more base stations into a quality parameter for the plurality of base stations; and
choosing at said centralized server new parameters to be implemented at each base station that result in an optimized performance across said plurality of base stations.

Abstract
A method and system for automatically configuring the frequency allocation within a cellular system or network. The method requires the collection of measurements from different parts of a cellular network, generating statistics from these measurements, and combining these statistics with inventory, propagation and geographic data. The combined data is used as input to a frequency allocation algorithm. As a result, the allocation algorithm produces a frequency configuration set, a quality measure of the configuration proposed and/or a set of recommendations that is fed back to the cellular base stations to re-allocate the frequency usage in a plurality of cells.

4. A method for determining an optimum frequency allocation for a wireless telecommunications network having at least one base station in a serving area, and comprising the steps of:
-
measuring at a mobile station the level of interference in a first frequency from all other frequencies received by said mobile station;
reporting said measurements to a centralized server;
comparing said measured interference levels at one frequency to all other frequencies measured at said mobile station; and
selecting from said measured frequencies a different frequency to be allocated for each of said base station to minimize the overall interference measurement at all said mobile stations. - View Dependent Claims (5, 6, 7)

12. A method of allocating frequencies in a cellular telecommunications system comprising the steps of:
-
receiving from a plurality of mobile terminals the measured received signal strength indicator for each frequency available for use by such mobile stations across a plurality of cellular base stations;
calculating a value representing the interference level for each frequency available for use in each of said transceivers in said cellular base stations;
