Abstract: A sound information providing system, which can eliminate inappropriate sound information, is provided. The sound information providing system includes a receiving unit that receives a phone number for identifying a cellular phone of the destination side and a phone number for identifying a cellular phone of the source side. Both information is transmitted from the cellular phone of the source side, a sound information requesting unit for requesting sound information based on the received phone number. A sound information monitoring unit monitors the sound information are output in response to the request. It eliminates inappropriate sound information, and selects the sound information conforming to a predefined condition. A transmitting unit transmits the selected sound information to the cellular phone.

Abstract: A sound information providing system, which can eliminate inappropriate sound information, is provided. The sound information providing system 10 comprises a receiving unit 101 for receiving a phone number for identifying a cellular phone 35 of the destination side and a phone number for identifying a cellular phone 30 of the source side, both information transmitted from the cellular phone 30 of the source side; a sound information requesting unit 102 for requesting sound information based on the received phone number; a sound information monitoring unit 103 for monitoring the sound information being output in response to the request, eliminating inappropriate sound information, and selecting the sound information conforming to a predefined condition; and a transmitting unit 104 for transmitting the selected sound information to the cellular phone 30.

Abstract: An object is to implement such a configuration that, where a call recipient sets a caller-side RBT, a caller can acquire information about the RBT. For achieving this object, a sound information providing system comprises a sound source information replicating part for replicating sound source information about the RBT under transmission to a cell phone in a call origination to another cell phone, prior to arrival at the cell phone; a relevant information acquiring part for acquiring relevant information about the sound source information on the basis of the replicated sound source information; and an acquisition result keeping part for storing the acquired relevant information in connection with a telephone number of the cell phone in an acquisition result storage.
