MOBILE PHONE SYSTEM AND MOBILE PHONE TERMINAL USING A PLURALITY OF TELEPHONE NUMBERS

摘要

The present invention relates to a mobile phone system and a terminal which assign a plurality of telephone numbers to single mobile phone. Suppose that there received a call request signal via a telephone interface unit 11. A controller 13 in mobile switching node searches for a phone terminal identification information corresponding to a called telephone number contained in the call request signal and checks whether a called mobile phone terminal uses a plurality of telephone numbers or not. If the controller 13 discovers the corresponding phone terminal identification information, it also extracts a phone number identification information associated with the called telephone number, and then corresponding call processing is performed based on the phone number identification number. Meanwhile, a mobile phone terminal extracts a phone terminal identification information contained in the call connection request signal received from mobile switching node and checks if the call connection request is for itself. If then, a phone number identification information, contained in the call connection request signal is extracted to enable a callee to recognize which telephone number is called among multiple phone numbers assigned.
