WIRELESS DEVICES, NETWORK COMPUTING DEVICES, AND THE METHODS IMPLEMENTED BY THESE DEVICES RELATED TO CUSTOMIZABLE RINGING SIGNALING CAPABILITIES

Abstract

The invention relates to a system and method by which a wireless device signals to a relevant network the capability of a customized ringing signal (CRS) and uses such information by the network. Different methods may receive from the network an INVITE message notifying the wireless device of an incoming call, determine whether the INVITE message indicates that the network provides CRS service if the wireless device supports CRS functionality, and include an indication in the response to INVITE that the wireless device supports CRS functionality. Different methods may include a network computing device receiving such information and making agreements for CRS service with the wireless device only when the wireless device indicates the capability of CRS functionality.
