The embodiments of the present invention provide a method, a system, a device, an MMSC, and a GW for implementing a multimedia service. To enable a person skilled in the art to better understand the technical solutions provided by the embodiments of the present invention, the present invention will be described below with reference to the accompanying drawings and specific embodiments. The technical solutions provided by the embodiments are further described in detail.

In the process of researching the prior art, the inventor found that since the sender and the receiver must follow the principle of the respective home service, the MMS between the sender's home MMSC and the receiver's home MMSC forwards traffic, causing additional MM4. The forwarding traffic of the interface, which occupies a large amount of network bandwidth; and the forwarding traffic generated through the MM4 interface occupies both the sender MMSC and The license of the MMSC of the receiving party is limited. The number of licenses of the MMSC is limited. Therefore, the license that is used by the MMSC and the terminal will be affected by the lack of a license.

FIG. 1 is a schematic diagram of a networking structure for implementing multimedia services according to the present invention. The MMSCs in the same carrier network are divided into two types: a local MMSC and a central MMSC. The local MMSC is a sub-area (for example, for a mobile operator network, different local MMSCs are allocated for different provinces). MMSC, local MMSC. Responsible for processing multimedia messages submitted by end users in the area and completing forwarding of multimedia messages, or forwarding multimedia messages that need to be sent to other carrier networks to the central MMSC for processing. The central MMSC has high reliability. It is the externally unique interface MMSC of all local MMSCs. It is interconnected with the MMSC or MMSIG of other carrier networks. It is responsible for forwarding multimedia messages sent by the local MMSC to the MMSC or MMSIG of other carrier networks, or for receiving. And forward the SP (Service Provider) message. The central MMSC serves as a backup node of other local MMSCs. When the local MMSC fails, it is used to replace the local MMSC for multimedia message transmission, so as to ensure uninterrupted service. The WAP GW (Wireless Application Protocol Gateway) is a gateway device for the mobile terminal to access the MMSC, and uses HTTP (Hypertext Transfer Protocol) communication with the MMSC. The SP provides rich value-added services for the terminal through the API (Application Program Interface) of the MMSC. The SP is only connected to the central MMSC, and the value-added service is transmitted between the local MMSCs through the central MMSC.

In the multimedia service implementation process, the terminal usually sets an MMSC address, where the MMSC address is the local MMSC address to which the terminal belongs, and the address determines the MM1_Submit.REQ (submit request) message, the MMl_Notification.RES (notification response) message or the terminal actively sent by the terminal. The destination of the MMl_Acknowledgement.REQ (confirm request) message. In order to enable the above-mentioned message submitted by the terminal to accurately reach the local MMSC to which it belongs, and to enable the MM1_Notification.RES message or the MM1_Acknowledgement.REQ message to directly return the original local MMSC that delivered the corresponding message, a message identification forwarding module is added for each MMSC. . In terms of networking implementation, the message identification forwarding module may be built in the local MMSC or the local WAP GW, or may be separately networked independently of the local MMSC and the local WAP GW; for the central MMSC, the message identification forwarding module may be built in the central MMSC. It can also be networked separately from the central MMSC. In order The message identification forwarding module is usually built in the MMSC or the WAP GW. As shown in FIG. 1, the message identification forwarding module 1 is located in the local MMSC1, the message identification forwarding module 2 is located in the MMSC2, and the central message identification forwarding module is located. Central MMSC. In addition, in order to complete the backup capability of the central MMSC to the local MMSC service, when transmitting the multimedia message service, the service is preferentially delivered to the local MMSC obtained according to the message identification forwarding module, and when the local MMSC fails, the message identification forwarding module will The business is delivered to the central MMSC for processing.
