Abstract
The present invention discloses a method for implementing resending of a short message, including: when an Internet Protocol short message gateway (IP-SM-GW) learns that in an Internet Protocol multimedia subsystem (IMS) domain, a short message fails to be sent to a receiver, sending, by the IP-SM-GW, the short message to a service center, so that the service center stores the short message; and when the receiver corresponding to the short message changes to available status, receiving, by the IP-SM-GW, the stored short message sent by the service center, and resending the short message to the receiver through the IMS domain, thereby implementing resending of a short message request failing to be sent, improving availability of sending the short message request in the IMS, and improving user experience.
