Method and system for transmitting multimedia message

Abstract

The invention discloses a method for transmitting a multimedia message. The method comprises the following steps that: a short message service center (SMSC) transmits a notification short message to a mobile terminal and a delivery status message to a multimedia messaging service center (MMSC); and when the MMSC determines that the notification short message is successfully delivered according to a delivery status code in the delivery status message, the MMSC finds a multimedia message according to a message identifier of the notification short message in the delivery status message and transmits the multimedia message to the SMSC. The invention also provides a system for transmitting the multimedia message. According to the technical scheme of the invention, the transmission accuracy and the success rate of the multimedia message are improved.

Description

technical field [0001] The invention relates to the field of multimedia message transmission, in particular to a method and system for sending multimedia messages. Background technique [0002] With the rapid development of mobile communication technology, especially the gradual development of 3G services in the communication market, the multiplication services of rich and colorful multimedia messages have become more and more popular, such as various mobile newspaper services, music on demand services, etc. It is more and more accepted by the majority of users, and the value-added service volume of multimedia messages is increasing rapidly every year, which puts forward higher and higher requirements for the success rate and accuracy rate of sending multimedia messages to users' mobile terminals. [0003] figure 1 is a schematic diagram of the system structure of the multimedia message service center in the prior art, figure 2 It is a schematic flow chart of sending mult...

Problems solved by technology

[0008] The first flaw is: the MMSC sends a notification message to the SMSC, and when the SMSC receives the message, it replies a confirmation message to the MMSC, telling the MMSC to receive the notification message, and the MMSC determines that the notification message has been received after receiving the confirmation message. Sending success, and continue the following operation; But, actual situation is that SMSC is not sent to the mobile terminal of receiver immediately after receiving the notification short message message that MMSC sends, but utilizes the mode of storing and forwarding (Short Message Protocol Specification The stipulations in ) are queued for delivery. After the actual delivery, the SMSC will no longer reply to the SSMC with the final result, so whether the multimedia message is actually delivered successfully is unknown to the MMSC, which will lead to some multimedia messages. Because the receiver's mobile terminal did not get it in time and was forwarded to the Montnets mailbox or expired, the success rate of sending multimedia messages decreased.

[0009] The second defect is: MMSC does not authenticate the number of the receiver's mobile terminal when sending a notification short message message by SMSC, so there will be an empty number or an abnormal number if the number of the receiver's mobile terminal (such as 120), the MMSC still sends notification SMS messages, which affects the accuracy of sending multimedia messages, and once the multimedia message expires and is successfully forwarded to the Montnets mailbox, the user also needs to deduct fees

[0010] Since the current MMSC has the above two defects in the processing of multimedia messages, the accuracy and success rate of receiving multimedia messages is difficult to achieve an ideal ratio. In addition, there are also problems such as deduction of fees for empty numbers, which will cause user frustration. complaint
