By the way, recently, portable telephones having new functions have been released one after another, and many people have bought the portable telephones themselves. When a mobile phone is changed to a new model, not only the model but also a new phone number is often changed. However, in the case of a mobile phone, even if a new phone number is changed, unlike a phone installed in a home or business as described above, a person who does not know that the phone number has changed Neither does the base station provide a service for notifying a changed telephone number. Therefore, there has been a problem that when the number of the mobile phone is changed, the telephone number is changed, and there is no means for knowing the number of the changed telephone number.

In addition, the telephone directory function for managing telephone numbers of a communication partner such as a mobile telephone and a PHS has no means for automatically converting a telephone number before change to a new telephone number after change. Had to manually rewrite the new phone number.

[0007] An object of the present invention is to make a call to an old telephone number corresponding to a changed telephone number when a portable telephone or PHS connected by wireless communication is used, and to make a call to the telephone number after the change of the other party. It is another object of the present invention to provide an identifier change notification system in a wireless portable terminal capable of automatically registering a portable telephone owned by the user and a telephone number changed to the telephone function of the PHS.

[0008]

According to a line connection request from a mobile phone or a PHS, a communication partner telephone is specified from a telephone number of a connection destination, and a line connection request is sent to a telephone exchange which establishes a line. Have the ability to transfer to another phone number. Thus, when a mobile phone or PHS that does not know the change of the telephone number issues a line connection request to the telephone number before the change, the line connection request can be transferred to the new telephone number. In addition, it has a function to multiplex communication lines established in mobile phones and PHS, etc. and a function to change the contents of the stored phonebook, realizing data exchange during calls and automatic telephone number change. I do.
