Abstract
The present invention concerns an equipment and a method for providing in connection with the fixed communications network (1) a small cellular extension (4), wherein the same kind of radio frequency mobile communication devices (9) can be used as in regular cellular networks (2), in other words, the radio interface (16) of the cellular extension (4) is similar to the radio interface (15) of the regular cellular networks (2). The cellular extension (4) comprises database means (11) for registering the subscribers and for transmitting the calls to the subscribers located in the cellular extension (4) based on the connections between the ISDN numbers of the cellular network determined for the cellular extension (4) and stored into the database means (11), and the IMSI codes of the subscribers. The invention doesn't require the same kind of signaling between the cellular extension and the regular cellular network as used in the regular cellular network (2) for implementing the data transfer between the mobile switching centers (5) and between the mobile switching centers (5) and the registers (7).
