Abstract: A method is provided for sending an Instant Message Disposition Notification (IMDN) request to a receiving terminal by a sending terminal in a Converged-IP Messaging (CPM) service. The sending terminal generates an instant message to be sent to the receiving terminal, inserts an IMDN request message into the generated instant message, the IMDN request message including a predetermined response limit time, and sends the instant message with the IMDN request message to the receiving terminal through a CPM server.

Abstract: A method and apparatus for providing a communication history of a terminal in a Session Initiation Protocol/Internet Protocol (SIP/IP) core network. When a user having a plurality of terminals sends a subscribe request for a communication history of the terminals to a server, the server transmits all communication history information associated with the plurality of terminals to any one of the terminals each time the communication histories associated with the terminals are newly registered. The terminal, which has received the communication history information, can request and receive presence information of a corresponding terminal, which is included in the communication history information, if needed.
