LOAD ESTIMATION FOR A CELL IN A WIRELESS NETWORK
First Claim
1. Method of estimating the load on a cell (11) in a wireless network, to which cell a number of mobile stations (16) are connected, comprising the steps of:
- obtaining (38, 56) measurement data (RC, PV, I) of the radio conditions of the links between said mobile stations and said cell,determining (30, 42, 54) link quality values based on the obtained measurement data, andsumming (32) the link quality values related to the mobile stations of the cell in order to estimate the total load (LTOT),wherein said method further comprises the steps of, for each mobile station (16) in a set of mobile stations connected to said cell,determining (46) a value (R) 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 (54) 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 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.

- 11. Method according to claim 11, wherein the step of determining that the session is no longer ongoing comprises comparing the adjusted link quality value with an unadjusted link quality value provided for the link and performing the step of stopping determining the degree of use and providing adjusted link quality values if this unadjusted value is lower than the adjusted value and setting this unadjusted value as the link quality value.

14. Cell load estimating device (22) for a cell (11) in a wireless network, to which cell a number of mobile stations (16) are connected comprising:
-
a data obtaining unit (28) configured to obtain measurement data (RC, PV, I) of the radio conditions of the uplinks between said mobile stations and said cell, and a cell load estimating unit (26) configured to determine link quality values based on the obtained measurement data, sum the link quality values related to the mobile stations of the cell in order to estimate the total load (LTOT), and for each mobile station (16) in a set of mobile stations connected to said cell, determine a value (R) indicative of the degree of use, by the mobile station, of a communication link provided for the mobile station during a communication session, and provide an adjusted link quality value (L-ADJUST) for the mobile station that considers this value indicative of degree of use of said link. - View Dependent Claims (15)
