Description

Method, system and device for realizing multimedia service

technical field

The invention relates to the technical field of communication, in particular to a method, system and device for realizing multimedia services.

Background technique

MMS Multimedia Messaging Service is a further development of SMS Short Messaging Service and EMS Enhanced Message Service. MMS provides an end-to-end solution for personal multimedia mobile communication services. MMS not only realizes information transmission between terminals, but also between terminals and applications, and also realizes the diversity of information, including various combinations of pictures, voice, images, data and text.

The existing multi-node MMSC (Multimedia Messaging Service Center, Multimedia Message Service Center) networking scheme adopts the scheme that the sender's home MMSC serves and the receiver's home MMSC serves at the same time. That is, when the sender submits a message, it must send the message to the MMSC of the sender's home, and when the receiver retrieves the message, it must go to the MMSC of the receiver's home to extract the message. When the sender MMSC and the receiver MMSC are different MMSCs located in the same operator network, when the sender submits a message, no matter where it roams, it needs to submit the message directly to the MMSC to which the sender belongs. The MMSC forwards the message to the MMSC to which the recipient belongs through the MM4 interface, and at the same time, when the recipient retrieves the message, no matter where it roams, it must retrieve the message from the MMSC to which the recipient belongs. When the MMSC to which the sender belongs and the MMSC to which the receiver belongs are MMSCs located between different operator networks, the above-mentioned MMSCs are connected through MMSIG (Multimedia Messaging Service International Gateway, multimedia message interconnection gateway). When the sender submits the message, No matter where you roam, submit the message to the MMSC to which the sender belongs. The MMSC to which the sender belongs sends the message to MMSIG, and the MMSIG forwards the message to the MMSC to which the receiver belongs. At the same time, the receiver is extracting the message. , no matter where it roams to, the message should be extracted from the MMSC to which the recipient belongs.

Detailed ways

Embodiments of the present invention provide methods, systems, devices, MMSCs, and GWs for implementing multimedia services. In order to enable those skilled in the art to better understand the technical solutions provided by embodiments of the present invention, the following describes the present invention in conjunction with the accompanying drawings and specific implementation methods. The technical scheme provided by the embodiment is described in further detail.

In the process of researching the existing technology, the inventor found that since the sender and the receiver must follow the principle of their respective home services, when forwarding traffic between the MMSC to which the sender belongs and the MMSC to which the receiver belongs, additional MM4 The forwarding traffic of the interface occupies a large amount of network bandwidth; and because the forwarding traffic generated through the MM4 interface will occupy the license (permission) of the sender MMSC and the receiver MMSC at the same time, because each MMSC has a limited number of licenses, so forwarding A large number of licenses occupied by the traffic will cause the transmission of multimedia services between the MMSC and the terminal to be affected due to the lack of licenses.

A schematic diagram of a network structure for implementing multimedia services in the present invention is shown in FIG. 1 . For the MMSC within the same operator network, it is divided into two types: local MMSC and central MMSC, where the local MMSC is an MMSC built in a sub-region (for example, for a mobile operator network, different local MMSCs are assigned to different provinces), and the local MMSC Responsible for processing multimedia messages submitted by end users in this area and completing the forwarding of multimedia messages, or forwarding multimedia messages that need to be sent to other operator networks to the central MMSC for processing. The central MMSC has high reliability. As the only external interface MMSC of all local MMSCs, it is interconnected with MMSCs or MMSIGs of other operator networks, and is responsible for forwarding multimedia messages sent by the local MMSC to MMSCs or MMSIGs of other operator networks, or responsible for receiving And forward SP (Service Provider, service provider) message. The central MMSC acts as a backup node for other local MMSCs. When the local MMSC fails, it is used to replace the local MMSC for multimedia message transmission, thereby ensuring uninterrupted services. WAP GW (Wireless Application Protocol Gateway, wireless application protocol gateway) is a gateway device for mobile terminals to access MMSC, and communicates with MMSC using HTTP (Hypertext Transfer Protocol, hypertext transfer protocol). The SP provides a wealth of value-added services for the terminal through the API (Application Program Interface) opened by the MMSC. The SP is only connected to the central MMSC, and realizes the transmission of value-added services with each local MMSC through the central MMSC.

In the process of implementing multimedia services, the terminal usually sets an MMSC address, which is the local MMSC address to which the terminal belongs. This address determines the MM1_Submit.REQ (submission request) message, MM1_Notification.RES (notification response) message or The whereabouts of the MM1_Acknowledgment.REQ (acknowledgment request) message. In order to enable the above-mentioned message submitted by the terminal to reach its local MMSC accurately, and to enable the MM1_Notification.RES message or MM1_Acknowledgment.REQ message to directly return to the original local MMSC that issued the corresponding message, a message identification forwarding module is added for each MMSC . In terms of networking implementation, the message identification and forwarding module can be built in the local MMSC or local WAP GW, or it can be networked independently of the local MMSC and local WAP GW; for the central MMSC, the message identification and forwarding module can be built in the central MMSC , and can also form a network independently of the central MMSC. In order to save networking costs, the message identification and forwarding module is usually built in MMSC or WAP GW, as shown in Figure 1, the message identification and forwarding module 1 is located in the local MMSC1, the message identification and forwarding module 2 is located in MMSC2, and the central message identification and forwarding module Located in the central MMSC. Moreover, in order to complete the backup capability of the central MMSC to the local MMSC business, when transmitting multimedia message services, the business is preferentially delivered to the local MMSC obtained by the message identification and forwarding module for processing. When the local MMSC fails, the message identification and forwarding module will The business is delivered to the central MMSC for processing.

The above notification message; or when the receiver is an SP, send a notification message to the central MMSC through the MMSC to which the sender belongs, and the central MMSC is located in the same network as the MMSC to which the sender belongs, and is used to notify the SP Forward the notification message.

The second embodiment of the implementation method of the multimedia service of the present invention is shown in Figure 3, this embodiment describes the implementation process of the multimedia service from the receiving side of the multimedia message:

Step 301: Receive a retrieval notification message, the retrieval notification message includes the information of the MMSC that provides the multimedia message.

Step 302: Determine the MMSC that provides the multimedia message according to the extraction notification message.

Specifically, the MMSC that provides the multimedia message is determined according to the identification information in the extraction notification message.

Step 303: Send an instruction message to the receiver to extract the multimedia message from the MMSC.
