Method and Apparatus for Implementing Resending of Short Message

A method for implementing resending of a short message, comprising:

• when an Internet Protocol short message gateway (IP-SM-GW) learns that in an Internet multimedia subsystem (IMS) domain, a short message fails to be sent to a receiver, storing, by the IP-SM-GW, a short message request corresponding to the short message failed to be sent;
• and
• when the receiver corresponding to the short message changes to available status, resending, by the IP-SM-GW, the stored short message request to the receiver through the IMS domain.

An apparatus for implementing resending of a short message, comprising:

• a storage processing module configured to, when it is learnt that in an Internet Protocol multimedia subsystem (IMS) domain, a short message fails to be sent to a receiver, send the short message to a service center such that the service center stores the short message;
• and
• a resending module configured to, when the receiver corresponding to the short message changes to available status, receive the stored short message sent by the service center, and resend the short message to the receiver through the IMS domain.

An apparatus for implementing resending of a short message, comprising:

• a storage processing module configured to, when it is learnt that in an Internet Protocol multimedia subsystem (IMS) domain, a short message fails to be sent to a receiver, store a short message request corresponding to the short message failed to be sent;
• and
• a resending module configured to, when the receiver corresponding to the short message changes to available status, resend the short message, which has undergone storage processing, to the receiver through the IMS domain.
