MOBILE RADIO COMMUNICATION SYSTEM

摘要

A mobile radio communication system in which setting of incoming-call refusal service for mail services such as short messages and electronic mail can be performed simply and reliably is disclosed. According to the system of the invention, an address conversion processing unit (43) is provided for converting addresses in such a manner that transmission-source information of a message can be handled by an IN node (20) that processes an incoming-call refusal service in telephone calls. This makes it possible to process the source of transmission using numerals even with regard to mail, received via a network such as the Internet, in which transmission-source information contains characters other than numerals.
