Embodiment 1
[0089] According to the short message transmission method proposed by the present invention, the process that non-IMS user C sends short message to IMS user A includes:
[0090] Step 31, the initiator UE submits the CS domain SMS to the SMSC;
[0091] Wherein, user C is the initiator UE, and user A is the receiver UE.
[0092] Step 32, the SMSC receives the CS domain SMS sent by the initiator UE through the CS domain;
[0093] Step 33, SMSC judges that user A is an IMS user;
[0094] Step 34, SMSC forwards the short message to SMS-GW;
[0095] Step 35, SMS-GW receives forwarding message from SMSC;
[0096] In step 36, the SMS-GW sends a message to the recipient UE through the IMS domain or the CS domain.
[0097] Step 36 includes:
[0098] Step 361, the SMS-GW judges whether the recipient UE has registered in the IMS network;
[0099] Step 362, under the condition that user A has registered in the IMS network, send a short message to the recipient UE through the IMS doma...
Embodiment 2
[0101] According to the short message transmission method proposed by the present invention, the process that IMS user A sends to IMS user B (not powered on) includes:
[0102] Step 41, the initiator UE submits the IMS domain SMS to the SMS-GW;
[0103] Step 42, the SMS-GW receives the SMS from the UE in the IMS domain, and fails to deliver the message to the IMS domain;
[0104] In step 43, the SMS-GW performs a retry processing on delivery failure.
Embodiment 3
[0106] According to the short message transmission method proposed by the present invention, the process that IMS user A sends to non-IMS user C includes:
[0107] Step 51, the initiator UE submits the IMS domain SMS to the SMS-GW;
[0108] In step 52, the SMS-GW receives the SMS from the UE in the IMS domain, and sends a message to the user C in the CS domain.
[0109] Based on the same or similar concept as the above embodiment, the embodiment of the present invention also provides a short message transmission device, which is set on the short message center SMSC, see image 3 , the short message transmission device that the present invention proposes comprises:
[0110] The first receiving unit 10 is configured to receive a short message sent by the first UE to the second UE;
[0111] A user identity judging unit 20, configured to judge whether the second UE is an IMS user or a CS domain user
[0112] The first forwarding unit 30 is configured to send the short message t...
