The present invention discloses a method and system for transmitting a large message mode Converged IP Messaging (CPM) message, wherein the method comprises the following steps that: when sending a large message mode CPM message to a CPM client of a receiver, a CPM client of a sender sends a session invitation message to the CPM client of the receiver and negotiates with the CPM client of the receiver to determine a media transmission link between the CPM client of the sender and the CPM client of the receiver; the CPM client of the sender sends the content of the large message mode CPM message to the CPM client of the receiver via the determined media transmission link; and the CPM client of the sender or the CPM client of the receiver initiates a flow to end the session of the large message mode CPM message. The present invention realizes the transmission of a large message mode CPM message. |
