The present invention discloses a method for delivering short messages in an IMS. The method includes: The sender encapsulates multiple concatenated short message segments into an IMS message, and sends the IMS message to the receiver; upon receiving the IMS message, the receiver extracts the short message from the IMS message. The present invention also discloses a system and apparatus for delivering short messages in an IMS. Through the embodiments of the present invention, the receiver can obtain a complete short message upon receiving the message. Besides, the present invention overcomes the problem that assembling multiple short message segments in the case of interworking between a short message and a SIP message cannot be realized at a receiver. Furthermore, the present invention reduces the number of SIP messages brought by short message segmentation in the IMS domain, thus decreasing the load on the network.
