Abstract
The invention relates to a radiotelecommunications system having a mobile terminal equipped with a subscriber identity module and designed to operate in a cellular network having a plurality of cells. The system has a private base station independent from the cellular network and connected to a wired telecommunications network. The private base station occupies at least a part of one of the cells of the cellular network, to which cell the cellular network has allocated at least one frequency from among all of the frequencies available in the cellular network; if it is situated within a zone close to the private base station, the mobile terminal can operate in cordless mode, in which it communicates with the wired network by communicating by radio with the private base station, radio communication taking place on at least one frequency selected from a predetermined set of one or more frequencies chosen from among all of the frequencies available in the cellular network except at least those frequencies which are allocated to said cell, the set of frequencies being pre-recorded in the subscriber identity module or in a memory zone of the terminal. According to the invention, said set of frequencies is transmitted to the mobile terminal by radio from a base station of the cellular network.
