Patent Images
1. A method of estimating the load on a cell in a wireless network, to which cell a number of mobile stations are connected, comprising the steps of:
- obtaining measurement data of the radio conditions of the links between said mobile stations and said cell,determining link quality values based on the obtained measurement data, andsumming the link quality values related to the mobile stations of the cell in order to estimate the total load,wherein said method further comprises the steps of, for each mobile station in a set of mobile stations connected to said cell,determining a value indicative of the degree of use, by the mobile station, of a communication link provided for the mobile station during a communication session, and providing an adjusted link quality value for the mobile station that considers this value indicative of degree of use of said link.

Abstract
The invention is directed towards a method of estimating the load on a cell in a wireless network as well as to a cell load estimating device. According to the invention a 5 determination (46) is made of a value (R) indicative of the degree of use, by a mobile station provided in a set of mobile stations connected to a cell, of a communication link provided for this mobile station during a communication session. Based on this value an adjusted link quality value (L-ADJUST) is provided (54) for the mobile station, which is then used when determining the cell load.
