摘要

The user of a cellular phone accesses a server using his/her own cellular phone via a base station, a telephone communication network and a base station control unit, to make a distribution request for music content data. The server distributes the requested music content data and a ringing tone to the cellular phone after the authentication of the accessing cellular phone is verified. Here, the user of the cellular phone only pays the price for music content data. Therefore, the user of the cellular phone can easily register or renew ringing tones.
