MOBILE COMMUNICATION METHOD AND SYSTEM THEREFOR

摘要

PROBLEM TO BE SOLVED: To enhance convenience by changing a call in a terminal during communication over to the one in another usable terminal with the same number when communication is hardly continued. SOLUTION: It is judged whether transfer changeover is performed to another shared terminal or not concerning one of the multiple terminals 1-3 where the same number is shared. When transfer changeover is judged, the terminal for transfer changeover is authenticated between the other shared terminals and a transfer changeover request to the authenticated terminal is outputted to a communication control station 30. The communication control station 30 performs a transfer changeover processing concerning the authenticated terminal based on the transfer change-over request which is outputted from the terminal.
