METHOD AND DEVICE FOR ESTIMATING AVAILABLE CELL LOAD

摘要

Methods and devices for determining the available load in a cell of a cellular radio system are provided where the determination of the available load is made in response to an estimated inter cell interference load. An estimated inter cell interference is determined. The inter cell interference change events are monitored by determining when a User Equipment changes serving cell or when a User Equipment adds or removes a cell to the active set of the User Equipment. The determined inter cell interference is adjusted by an estimated load caused by the User Equipment causing an interference change event, and the available load is determined in response to the adjusted inter cell interference. The method can continuously update inter cell interference. Moreover, the update can be made fast and thereby allow an improved estimation of the available cell load.
