Abstract
In a method of communicating with a mobile station in a cell of a cellular telecommunication network having a microcell layer with a plurality of microcells each comprising at least one relay station and a macrocell layer with a macrocell covering a plurality of microcells, a call in the microcell layer is effected between the mobile station and a set of relay stations, the number of which is a cardinal number at least equal to two, allocated to the call. The relay stations allocated to the call can change during the call, and the call is handed over from the microcell layer to the macrocell layer when it is not possible to allocate to the call a number of relay stations corresponding to the cardinal number. A base transceiver station for implementing the invention is also disclosed.
