Abstract: A method for setting telecom ring tones. A user registers with a common service platform or server. The common service server uploads the registration data to a home location register or local directory of registered users on a telecom switch or server. When the registered user makes a call or receives a call, the local directory verifies the user is registered. Then the telecom exchange connects to an added-service server. The added-service server processes the ring tone according to settings made by the user, so that the registered user or a caller calling the registered user hears the desired ring tone until the call is connected. The registered user can establish groups of callers so that appropriate ring tones are played for the suitable group. Additionally, priority can be set to pre-empt default tones according to the season, holiday, birthday, situation, or time.
