Abstract: PROBLEM TO BE SOLVED: To provide a device, a method and a system is preparation for decision and operation of a caller number by utilizing digit analysis. SOLUTION: A network interface receives an incoming message which has a received caller number and transmits an outgoing message. A memory stores plural digit trees for digit analysis and a plurality of available operations as a module of a database. A processor applies digit analysis of the received caller number to decide on pattern matching and decides a selected operation, conducts the selected operation with respect to the received call number to generate a corrected caller number. The processor instructs the network interface to transmit the corrected caller number included in the outgoing message, when the pattern matching is decided and instructs the network interface to transmit the received caller number included in the outgoing message, when the pattern matching is not decided.
