Abstract
A telecommunication system for mobiles of the type which has a network of base stations to which the mobiles can be connected and which is designed so that a mobile connected to a base station sends to the base station, besides user signals, power control commands in order that the base station controls its own transmission power so that the power received therefrom by the mobile is equal to a predetermined value. Each base station to which the mobile is connected regularly transmits, to the base stations to which the mobile is liable to be connected during a handover phase, the mean value of its transmission power. A base station, at the moment of the start of the handover phase, deduces, from the mean value and from the power control commands it receives from the mobile, the instantaneous value of the power emitted by the initial base station or stations at this moment and initializes its transmission power to a value derived from the instantaneous power.
