A system is provided for transmitting/receiving alerting information in a
wireless communication system. A calling mobile terminal (MT) encodes a
session initiate protocol (SIP) invite message comprising multimedia
alerting information and transmitting the encoded SIP invite message. An
Internet protocol multimedia subsystem (IMS) server receives the SIP
invite message from the calling MT, and transmits the SIP invite message
to the called MT according to service profile of the calling MT and the
called MT. The called MT decodes encoded multimedia alerting information
in the received SIP invite message and message and plays back the
multimedia alerting information.
