A control signaling network comprises broadcast layers (80-111) in a tree-like arrangement and, if necessary, means (10-33) provided between the broadcast layers to check whether the broadcast data is to be passed or discarded. A mobile switching center (1-8) has a location registration data table (40-44) for storing a location registration area identification of a mobile apparatus and a broadcast data table (50-52) for storing identifications of the broadcasts layers governed by a different mobile switching center required to broadcast the broadcast data for mobile station call or identifications of broadcast layers governed by the different mobile switching centers.
