Mobile communication technology has developed by leaps and bounds from the first generation analog communication system to the second generation digital communication system, and then to 3G, 4G and 5G. In the second generation of mobile communication technology, GSM is the most widely used.
On the basis of the original GSM network, GPRS superimposed a network supporting high-speed packet data, providing users with WAP browsing (browsing Internet pages), e-mail and other functions, which promoted the first leap development of mobile data services and realized the perfect combination of mobile communication technology and data communication technology (especially Internet technology).
Extended data:
GPRS network is a bearer network under the application layer, which is used to carry data services such as IP or X.25 Because GPRS itself adopts IP data network structure, the IP application protocol structure based on GPRS network can be understood as a two-layer IP structure, that is, the application layer IP protocol and the GPRS system itself use IP protocol.
Without the support of GPRS, you are roaming on the internet and have telephone access at this time. In most cases, you are not allowed to connect the incoming call continuously and dial the Internet again after the call. With GPRS, this conflict can be easily solved.
