The birth date of text messaging
May 17th
In 1992, when the world’s first text message was sent via PC on the GSM network of Wolfon in the UK When the message was successfully sent to the mobile phone, no one would have thought that this low-cost text message service originally launched by telecom operators to solve the problem of high mobile phone bills, this seemingly childish communication tool, would actually It will have such a great impact on people's economic and cultural life and even politics for many years.
SMS sending and receiving process
SMS is a telecommunications service produced with the digital mobile communication system. It transmits text or digital short messages through the signaling channel and signaling network of the mobile communication system. Information is a non-real-time, non-voice data communication service.
SMS messages can be originated from mobile communication terminals (mobile phones), or from the SMS platform servers of mobile network operators. They can also be sent by network service providers SP (including ICP) that are interconnected with the SMS platforms of mobile operators. , ISP, etc.).
In terms of technical means for realizing SMS business functions, although sending and receiving point-to-point messages through mobile phone terminals occupies a mainstream position, it is not the only form. Landline phones, PHS and the Internet are becoming new tools and carriers. .
At the beginning of the development of the SMS business, the sending and receiving of SMS started with the mobile phone and finally reached the mobile phone, passing through network elements such as GSM network/CDMA network and SMS center; with the emergence of SMS on-demand and customized services , mobile phones, Internet sites, and SMS value-added service systems can send text messages to each other. Internet sites and SMS value-added service systems have become new network elements. GSM/CDMA networks and SMS centers still maintain the core position of the SMS network; with the fixed telephone network as the core The basic "PHS" mobile phone appeared in China, and the SMS service was extended to the fixed network. The terminal is no longer limited to mobile phones. PHS mobile phones or special fixed terminals can be the senders and receivers of SMS, and the network foundation is no longer limited to GSM. /CDMA network and other digital mobile networks, fixed network can also become the network foundation of SMS, and the elements of SMS network have undergone significant changes.
As text messages expand from mobile phones to PHS and fixed terminals, and from digital mobile communication networks to fixed telephone networks, people’s understanding of text messages is no longer just a "patent" for digital mobile phones. Business forms are changing, network elements are changing, and information content is enriching. There are only two things that remain unchanged in this process:
First, the length of the text message is always no more than 160 English or numeric characters. characters, or 70 Chinese characters, which is closely related to the mechanism by which SMS messages are based on the signaling network of the communication system to transmit content. The second is the method of text message delivery - storage and forwarding. When the user cannot receive it, the text message will not be lost and will be temporarily stored in the SMS center. When the user logs back into the network, the text message will be quickly delivered to the user's mobile phone.
These inherent characteristics make text messages have the advantages of accurate, reliable, rapid and timely delivery, and give text messages the basic conditions to influence people's habits!
SMS as a mobile phone A business on the Internet that turns mobile phones that originally have language transmission functions into telegraph-like interpretation tools, leaving ears idle and allowing words to play a greater role; SMS, as a way to transmit information and communicate with words, allows thumbs to With developed agility and rest for the mouth, modern telecommunications business has a dual color of technology and culture.
Development
The world attributes the advent of the first mobile phone in 1973 to Martin Cooper, the chief designer of Motorola, and it was not until nearly 20 years later that the most valuable mobile phone An additional text message service was announced. In 1992, Acision put the first Short Message Service Center (SMSC) system on the market. It was originally designed to investigate and improve the reliability of the developing mobile phone market. Later, Norway's local telecommunications company Telenor Became the first contract company of SMSC.
From the original simple "SMSC box" to the current Acision IP SMSC system, Acision has increased the single-channel processing speed of short message text services to 16,000 messages per second, and its upper limit is endless. Based on expectations for the current level of technological development, Acision's future IMS-enabled platform will be able to provide users with higher quality services while reducing expenses. This technology is of immeasurable value to the market, and SMSC's innovation will never be stop.
In 1992, SMSC 1.0 version only had the ability to process 10 text messages per second. It was not until 1999 that the industry saw the first high-speed SMSC system. Acision company increased its processing capacity to 500 messages. per second, and the latest Acision IP SMSC system has increased this number by 32 times.
Despite the rapid development of the mobile market, SMS is still its most important value-added service. According to previous statistics from IDC, text messaging is still the mobile service with the highest penetration rate among mobile phone users in the Asia-Pacific region. Even in developing SMS markets, such as Western Europe, the usage rate of SMS services has reached 90%.
