The invention provides a method, equipment and system for forwarding a short message. When a roaming terminal roams in a network under a destination gateway conforming to an international standard signaling interworking specification of MAPv1 version, the destination gateway receives a routing information inquiry request for inquiring an address of a present MSC (Mobile Switching Center) of the roaming terminal sent by a source gateway, and inquires of a destination HLR (Home Location Register) about the address of the present MSC of the roaming terminal; the destination gateway sends a routing information inquiry response to the source gateway to instruct the source gateway to send the short message; the destination gateway receives the short message sent from the source gateway to the roaming terminal, and forwards the short message to the MSC according to the address of the present MSC of the roaming terminal obtained by the inquiring. The invention solves the problem that the short message can not be sent to the roaming terminal which is roaming in another operator network under MAPv1 version of GSM.
