A mobile communication system includes at least one subscriber database containing subscriber data and exchanges connected to each other by communication paths. At least one of the exchanges includes means for transmitting a request to the subscriber database. The request includes at least a B-subscriber number to a terminating call. To provide a system that is capable of selecting the optimum communication path for a terminating call, the subscriber database includes means for retrieving and transmitting to an exchange, a basic service code that corresponds to the B-subscriber number included in the request. The exchange includes means for routing the terminating call to the B-subscriber number by using communication paths that fulfill the property requirements of the call type indicated by the basic service code.
