Abstract:
1. For use in a cellular radio communications system including a first radio network controller (RNC) controlling a first set of cells, a method performed by the first RNC comprising: establishing a first connection between a first mobile radio and the first RNC through one of the first set of cells; detecting a handover of a second connection involving a second mobile radio moving from a cell in a second set of cells controlled by a second RNC to the one cell; and wherein the first mobile radio being currently served by the one cell controlled by the first RNC corresponds to a non-drifting mobile radio and the second mobile radio, whose second connection has been handed over from a cell controlled by the second RNC to a cell controlled by the first RNC, corresponds to a drifting mobile radio after the handover, and wherein the second connection is still controlled by the second RNC after the handover, the first RNC determining first management information for the non-drifting mobile radio in the first cell; the first RNC estimating second management information for the drifting mobile radio based on the first management information for the non-drifting mobile radio in the first cell using information associated with a number of drifting mobile radio connections in the first cell and a number of non-drifting mobile radio connections in the first cell; the first RNC providing to a management entity, external to and separate from the first and second RNCs, the first and second management information, wherein the management entity uses the first and second management information from the first RNC to generate management statistics for the cellular radio communications system.
