What are the characteristics and differences between SMS and MMS?

Short message is a telecommunication service in digital mobile communication system. It is a non-real-time and non-voice data communication service to transmit text or digital short messages through the signaling channel and signaling network of mobile communication system.

SMS can be initiated by mobile communication terminals (mobile phones), SMS platform servers of mobile network operators, and network service providers (including ICP and ISP). ) interconnected with the SMS platform of mobile operators.

In the technical means to realize the function of short message service, sending and receiving point-to-point messages through mobile terminals occupies the mainstream position, but it is not the only form. Fixed telephone, PHS and Internet are becoming new tools and carriers.

At the beginning of the development of short message service, the sending and receiving of short messages started from mobile phones, and finally went to mobile phones, passing through GSM network /CDMA network, short message center and other network elements; With the emergence of short message on demand and customized services, mobile phones, Internet sites and short message value-added service systems can send short messages to each other. Internet sites and short message value-added service systems have become new network elements, while GSM/CDMA networks and short message centers still maintain the core position of short message networks. With the emergence of PHS mobile phone based on fixed telephone network in China, the short message service has been extended to fixed network, and the terminal is no longer limited to mobile phone. PHS mobile phones or dedicated fixed terminals can be used as the sender and receiver of short messages, and the network foundation is no longer limited to digital mobile networks such as GSM/CDMA networks. Fixed network can also become the network foundation of short message, and the elements of short message network have changed significantly.

With the extension of short messages from mobile phones to PHS and fixed terminals, and from digital mobile communication network to fixed telephone network, people's understanding of short messages is no longer just regarded as the "patent" of digital mobile phones. Business forms are changing, network elements are changing, and information content is rich. There are only two things that remain unchanged in this process: First, the message length of short messages is always less than 160 English or numeric characters or 70 Chinese characters, which is different from that of traditional short messages. The second way is to send short messages-store and forward. When the user does not receive it, the short message will not be lost and will be temporarily stored in the short message center. When the user logs on to the network again, the short message will be quickly submitted to the user's mobile phone.

These innate characteristics make short messages have the advantages of accuracy, reliability, rapidity and timely delivery, and make short messages have the basic conditions that affect people's habits!

As a kind of service on mobile phone, SMS has turned the mobile phone with language transmission function into a telegraph-style interpretation tool, which makes the ears idle and the words show greater role; As a way of transmitting information and communication by words, SMS makes the thumb sensitive and developed, and gives the mouth a rest. Modern telecommunication services have dual colors of technology and culture.

1992, the world's first short message was successfully sent to the mobile phone through the computer on the network of Vodafone company in Britain, thus announcing the birth of mobile phone short messages. As for when and where the first short message in China was born, it is unknown, but according to research, the mobile communication network in China had the short message function as early as 1994, but people with mobile phones didn't need it at all. With the increasing popularity of mobile phones, since 1998, China Mobile and China Unicom have successively expanded their short message services on a large scale: in 2000, the number of short messages in China exceeded 1 100 million; 200 1 year reaches18.9 billion; In 2004, this figure soared to 90 billion. So SMS naturally became the fifth communication tool, and the formulation of "believing in life" was born; So from 1998 to now, in a few years, whether you like it or not, short messages have gradually entered our lives and become a part of our lives, and our lives have also changed because of short messages.

The English name of MMS is MMS, which is the abbreviation of multimedia messaging service, meaning multimedia messaging service, and is often called MMS. Its biggest feature is that it supports multimedia functions and can transmit comprehensive content and information, including text, image, sound, data and other multimedia formats.

Technically speaking, MMS is not a short message, but with the support of GPRS network and WAP wireless application protocol as the carrier to transmit pictures, sounds, words and other information. MMS service can realize instant multimedia information transmission from mobile phone end-to-end, from mobile phone terminal to Internet or from Internet to mobile phone terminal.
