Abstract:
In order to solve the problem in that information relating to a specific purpose can be saved in the internal memory of a mobile apparatus on which a permanent memory is mounted while information relating to other purpose cannot be saved in the internal memory of the apparatus, the purpose of each telephone call is distinguished by sending a non-telephone type notice before transferring the call and thus the user can determine whether the call should be saved or not.
