| 摘要 |
The present invention provides method and apparatus for determining a cell border between first (A) and second (B) cells in a cellular communications system, such as GPRS, in which communications with mobile stations (1, 1H) c an be effected at different effective transfer rates (CS1 to CS4) in dependence upon communication conditions. Information relating to the transfer rates (C S1 to CS4) of communications with mobile stations immediately before and after cell handover from the first cell (A) to the second cell (B) is stored. The stored information is subject to analysis and processing, and in dependence on the results the cell border between the first (A) and the second (B) cell is determined such that, at handover, transfer rates (CS1 to CS4) before and after handover are more likely or most likely to be the same.
