| 摘要 |
The invention relates to a method for interference analysis in a mobile radiotelephone network having an adaptive antenna in at least some of its cells (Fig. 4 BSi) and comprising traffic channels and control channels, wherein (Fig. 6) the interference ratio (C/I or I?ij?) of interference (I) in one traffic channel of an adaptive antenna of a first cell (BSj) is calculated in the traffic channels of an adaptive antenna of a second cell (BSi), wherein (Fig. 5) the interference ratio (I?ij?) of interference in a traffic channel or a first cell (BSj) not having adaptive antennae is calculated in a traffic channel of a second cell (BSi) having an adaptive antenna, wherein (Fig. 7) the interference ratio of interference in a control channel of a first cell (BSi) having or not adaptive antennae is calculated in the control channel of a second cell (BSj) having or not adaptive antennae in relation to the entire surface of the cell on the basis of the useful signal-interference signal ratio ((I?j?,i)_tb) in said control channels in the entire surface of the cell without considering the possible adaptive antennae of one or both previously mentioned cells (BSj, BSi).
