Abstract
Wireless networks and methods provide call waiting distinctive ringback. A wireless network of the invention comprises a switching system and a subscriber database. The switching system receives a registration request from a mobile device of a subscriber, transmits a registration message to the subscriber database, and receives a response message from subscriber database that includes a call waiting distinctive ringback indicator for the subscriber. If the switching system receives a call attempt from a calling party directed to the mobile device of the subscriber that is busy, then the switching system processes the call waiting distinctive ringback indicator to determine the type of ringback to provide for the call attempt, either distinctive ringback or non-distinct ringback.
