Regulation of traffic load of fixed stations in a cellular radio communication network
First Claim
1. A method of regulating traffic loads in fixed stations which are respectively included in and associated with cells in a cellular radio communication network where mobile stations measure radio-electric fields transmitted by said fixed stations,said method comprising, relating to each of said fixed stations, the steps of:
- computing a field correction parameter as a function of at least a load indicator of each of said fixed stations depending on the traffic supported by each of the fixed stations and periodically re-evaluated, and on fixed factors, andtransmitting said field correction parameter to said mobile stations, and, relating to each of said mobile stations, the step of;
correcting the measured radio-electric field corresponding to each of said fixed stations by said correction parameter into a corrected field, so that each of said mobile stations compares respective corrected fields corresponding to said fixed stations and selects the one of said fixed stations corresponding to the highest corrected field to establish a radio communication with the selected fixed station.

Abstract
The process aims to constantly optimize the distribution of the radio-electric load on a radio communication cellular network between fixed relays. This is equivalent to increasing or reducing the surface of network cell when the traffic in the cell decreases or increases. Each relay transmits a field correction parameter as a function of a load indicator and fixed factors so that each mobile station corrects the radio electric field and selects the relay corresponding to the highest corrected field. The correction parameter of a relay in a given cell also depends on overload indicators relating to adjacent cells and indicators of field boundary displacements with respect to cells adjacent to the given cell.
