What is MMS? Why do I receive the same MMS every day?

MMS in MMS short message is the abbreviation of multimedia message service, and Chinese translation is multimedia short message service. China Mobile Company named it "MMS", which can be used to transmit multimedia information such as text, pictures, animation, audio and video.

MMS is the abbreviation of Multimedia Messaging Service, and its Chinese name is Multimedia Messaging Service. The industrial standard of MMS is formulated by WAP Forum and 3GPP (3G Partnership Project).

Therefore, MMS is designed to run on the upper layer of WAP protocol, not limited to transmission format, but also supports circuit-switched data format and general packet radio service format.

Its working principle is to use high-speed transmission technology EDGE (enhanced data rate is? GSM？ Electronic solution is a new technology to improve data rate, and it is a step in the transition from GSM to the third generation mobile communication system IMT-2000. It is also called "GSM 384" because this technology can increase the data rate from the current 9.6kbit/s to 384 kbit/s.

This rate can support voice, Internet browsing, e-mail, conference TV and other high-speed data services) and GPRS support, with WAP (Wireless Application Protocol) as the carrier to transmit video, pictures, sound and text.

Extended data

Multimedia messaging service does not depend on the basic network, and can be implemented in the second, second, fifth and third generation wireless networks, and MMS service can be supported by GSM, GPRS and WCDMA networks. Considering the network bandwidth and data transmission speed, MMS service will take off in the current GPRS network and mature in the future 3G network.

After the multimedia message is synthesized, the mobile phone terminal can send the multimedia message to all legal users in the network, and the multimedia message center MMSC stores and processes the multimedia message, and is responsible for forwarding the multimedia message between different MMSCs. At the same time, the receiving user can receive multimedia messages from MMSC.

Multimedia message service needs WAP gateway, data transmission network (such as circuit-switched network, GPRS or WCDMA network) and short message center. At present, MMS service is carried by WAP, and SMS is used as a reminder, which is automatically extracted from MMS center MMSC by MMS mobile phone. In the eyes of users, MMS, like SMS, is sent from the MMS center on its own initiative.
