ABSTRACT:
Communication type identification data and message data are sent to a called (call incoming side) apparatus during a communication path formation operation with a desired destination apparatus through a communication medium. The destination apparatus identifies the identification data, and generates different ringing tones corresponding to communication types. When the destination apparatus receives a message, it simultaneously displays the message. A receiving party can easily discriminate the communication types, and can take appropriate reactions, thus allowing efficient response without requiring unnecessary answering process.
