Problems solved by technology

[0005] There is a big difference between IMS domain message processing and CS domain message processing. For the 3GPP2 integration solution, the existing network SMSC needs to be greatly modified, which will bring great difficulties to the operation and bring unavoidable problems to the existing network applications. estimated impact

Embodiment 1

[0087] 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:

[0088] Step 31, the initiator UE submits the CS domain SMS to the SMSC;

[0089] Wherein, user C is the initiator UE, and user A is the receiver UE.

[0090] Step 32, the SMSC receives the CS domain SMS sent by the initiator UE through the CS domain;

[0091] Step 33, SMSC judges that user A is an IMS user;

[0092] Step 34, SMSC forwards the short message to SMS-GW;

[0093] Step 35, SMS-GW receives forwarding message from SMSC;

[0094] In step 36, the SMS-GW sends a message to the recipient UE through the IMS domain or the CS domain.

[0095] Step 36 includes:

[0096] Step 361, the SMS-GW judges whether the recipient UE has registered in the IMS network;

[0097] 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

[0099] 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:

[0100] Step 41, the initiator UE submits the IMS domain SMS to the SMS-GW;

[0101] 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;

[0102] In step 43, the SMS-GW performs a retry processing on delivery failure.

Embodiment 3

[0104] 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:

[0105] Step 51, the initiator UE submits the IMS domain SMS to the SMS-GW;

[0106] 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.

[0107] 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:

[0108] The first receiving unit 10 is configured to receive a short message sent by the first UE to the second UE;

[0109] A user identity judging unit 20, configured to judge whether the second UE is an IMS user or a CS domain user

[0110] The first forwarding unit 30 is configured to send the short message t...

Abstract

The present invention proposes a short message transmission method, device, and system. The method includes: receiving a short message sent by a first user equipment UE to a second UE; when the second UE is an IMS user, transmitting the short message Send the short message to SMS-GW; if the second UE is a CS domain user, send the short message to the second UE. Through the scheme of the present invention, the short message center only needs to complete the identification and forwarding of the type of the called user, and the delivery, retry, and storage of the IMS user are still completed by the SMS-GW, and there is no need to carry out a large Retrofitting only needs to add a user type identification function and the function of forwarding short messages to SMS-GW, which has little impact on the operation of the existing network, and provides a feasible transition solution for the development of IMS bearer short message services, reducing Implement risks to ensure a smooth transition to converged messaging applications in the future.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a short message transmission method, device and system. Background technique [0002] In the existing mobile data communication, the CS (Circuit-Switched, circuit-switched) domain short message service is a widely used service, and is generally used in the existing 2 / 3G environment. IMS (IP Multimedia subsystem, IP Multimedia Subsystem) is a subsystem supporting IP (IP Internet Protocol, Internet Protocol) multimedia services, and is usually applied in a 4G environment. With the emergence of the IP multimedia service subsystem, it is necessary to solve the short message sending and receiving problem under the coexistence of traditional short messages and IMS domain short messages. [0003] The 3GPP2 (3G Partnership Project 2, 3rd Generation Partnership Project 2) specification introduces a Short Message Service Gateway (SMS-GW), which serves as a store-and-forward service gatew...
