The invention relates to a telecommunications system that includes a number of calling subscriber apparatus (5), a number of telephone exchange units (1) and a number of called subscriber apparatus (8). The system is adapted to enable a call incoming from a selected permanent sytem-associated subscriber apparatus or a mobile system-associated subscriber apparatus to be transferred to a selected permanent subscriber apparatus or a selected mobile subscriber apparatus, through the medium of a selected telephone exchange unit and its associated computer equipment. Subsequent to having received a call, the telephone exchange unit (1) and/or the computer equipment (10) establishes or evaluates the geographical area and/or location of the calling subscriber apparatus. The telephone exchange unit and/or the computer equipment evaluates, establishes and stores (104) the geographical areas and/or locations applicable to each of a number of available subscriber apparatus. One of the available subscriber apparatus requested by the calling subscriber and evaluated and indicated, or selected, by the telephone exchange unit is called through the medium of a circuit (105) belonging to the telephone exchange unit. Subsequent to having noted the call from the telephone exchange unit, the indicated subscriber apparatus (8) calls the telephone exchange unit (1) and a connection is set up with the input connection of a second telephone exchange unit through the medium of a telecommunications system and the first and the second input connections are mutually connected by switches in the telephone exchange unit, for direct speech connection. |
