Abstract
A method for implementing information exchange is disclosed in the present invention, and the method comprises: a calling user terminal sending information to be sent to a called user terminal by carrying the information in a user-to-user signaling (UUS) field of a call message; the called user terminal sorting out the information carried in the UUS field from the call message after receiving the call message, and feeding back a message other than an acknowledge message to the calling user terminal; the calling user terminal terminating this call after receiving the message fed back by the called user terminal. The simplicity and the easy transformation of the software update of user terminals are fully utilized in the present invention; therefore the present invention can enable a user terminal to have the information exchange function only by properly modifying the software of the user terminal.
