A telephone and data network for mobile subscribers comprises radio concentrators locally distributed in the overall area of a radio network which can communicate via radio with the mobile subscribers and comprises radio exchange offices associated with one or more concentrators connected to the public telephone system and, if applicable, for the purpose of data transmission between mobile subscribers and subscribers to the public data network to the teleprinter and data network. The call number of each mobile subscriber and the area code corresponding to his location in any particular case with respect to the associated radio exchange and/or the associated radio concentrator, are retrievably stored in a local memory associated with the corresponding local area and one global memory is associated, in each case, with a plurality of the local memories, to which global memory the data concerning the prevailing location of all mobile subscribers of the large area from the individual local memories, are transmitted and are retrievably stored. A central computer controls the exchange of the data relating to the subscribers' location between the local memories and the global memories. |
