View Patent ↗A method and system, suitable for using an original entertainment file for playing as a ring tone on a communication device ( 104 ), is provided. The method includes decrypting ( 304 ) a part of the original entertainment file using an authorization key upon receiving an incoming call signal. The part of the original entertainment file is played ( 306 ) until the incoming call signal is acknowledged. The method further includes decrypting ( 308 ) a remaining part of the original entertainment file using the authorization key after the incoming call signal is acknowledged.
