To provide a mobile communication network, enabling a single mobile terminal to utilize a plurality telephone numbers for transmission and capable of avoiding the nonconformities that depend on misoperations by user, without having to add extra functions to the mobile terminal, and to provide a communication method and a database apparatus.
A mobile communication network 10 is provided with a database 18. The database 18 stores a physical telephone number T1, a logic telephone number T2, and a telephone number T3 of a transmission permissible destination. Upon receiving transmission from a mobile terminal 12a, a subscriber step exchange 14a searches the database 18. Then, the exchange 14a determines whether a destination telephone number X1 for the transmission matches the destination telephone number registered in the transmission permissible telephone number T3. If there is a match, the exchange 14a allows this transmission to arrive at the destination telephone number X1 (mobile terminal 12b) as transmission due to the logic telephone number T2.
