GPRS is the English abbreviation of General Packet Radio Service (General Packet Radio Service), a new packet data bearer service developed on the existing GSM system.The most fundamental difference between GPRS and the existing GSM voice system is that GSM is a circuit-switching system while GPRS is a packet-switching GPRS is a packet switching system. Therefore, GPRS is particularly suitable for intermittent, bursty or frequent data transmission of small amounts, as well as for occasional transmission of large amounts of data. This characteristic is just right for most mobile interconnection applications.
What are the advantages of GPRS?
Real-time online: "Real-time online" means that the user is connected to the network at all times. For example, when the user accesses the Internet, the cell phone sends and receives data on the wireless channel, even if there is no data transmission, the cell phone has always been connected to the network, not only by the user side of the initiation of data transmission, but also from the side of the network at any time to start the push class business, not like ordinary dial-up Internet disconnection as well as have to re-dial in order to surf the Internet.
Billing by volume: Users can be online all the time and are charged according to the number of packets received and sent by the user, and when there is no data traffic transmission, users are not charged even if they are hanging out on the Internet.
Quick login: GPRS users are always attached to the GPRS network as soon as they turn on their computers, and each time they use it, they only need an activation process, which usually takes only 1-3 seconds to log on to the Internet immediately.
High-speed transmission: GPRS adopts packet-switching technology, and the highest theoretical data transmission rate can reach 171.2kb/s. Circuit-switched data service, the rate of 9.6K bits per second, so the relationship between circuit-switched data service (referred to as CSD) and GPRS is just like the difference between a 9.6K Modem and a 33.6K or 56K Modem.
Switching: GPRS also has the advantage that data transmission and voice transmission can be carried out simultaneously or switched. This means that users can receive voice calls while surfing the Internet with their cell phones. This means that users can receive voice calls while surfing the Internet on their mobile phones.
What can GPRS bring to users? In particular, what are the applications that are different from the existing GSM?
GPRS mobile data service can provide users with rich application services, such as:
Mobile business: including mobile banking, mobile financial management, mobile trading (stocks, lottery), etc.
Mobile information service: information on demand, weather, travel, services, web pages, news and advertisements, etc.
Mobile Internet service: web browsing, Email, etc.
Mobile internet service: web browsing, mobile internet service: web browsing, email, etc.
Mobile Internet service: web surfing, web surfing, web surfing, web surfing, etc. Email, etc.
Virtual Private Network (VPN) services: mobile office, mobile healthcare, etc.
Location-based services: location search, navigation in restaurants and similar service industries, etc.
Multimedia services: video telephony, multimedia messaging, on-line gaming, on-demand music and video screens, etc.
Personal services: PIM and other services tailored for individuals, etc. business, and so on.
It is worth noting that GPRS also has the characteristics of resource **** enjoyment, rich bandwidth, etc. It is not a business in itself, but a better way to carry the network, so even the same application will be enhanced because of the above characteristics of GPRS, of course, due to the technical characteristics of GPRS itself, there are some applications and services that are particularly suitable for GPRS network, such as Online chatting, mobile stock trading, remote monitoring, remote counting, and other data services with low traffic and high frequency transmission.
Applications of GPRS
GPRS is the mainstream technology that supports China Mobile's "Mobile Dream Network" and moves towards the 3G world.
Currently, China Mobile's GPRS network has covered all provinces, municipalities and autonomous regions in China, with networks in more than 240 cities. No matter in the busy downtown or in the remote areas, GPRS can provide high-speed data services to the maximum extent for the new human beings, business people and customers of various industrial groups.
More than 200 of the world's largest carriers have chosen GPRS networks, and GPRS data services can reach all over the world. Meanwhile, China Mobile users can already realize GPRS free communication with Hong Kong, Taiwan and Singapore, realizing the concept of true mobile data wireless interconnection.
About cell phones
The world's major cell phone manufacturers, have GPRS cell phone to provide, the current market sales of GPRS cell phone there are more than twenty, and all grades of cell phones are available. Colorful screens, rich, powerful features, and multimedia support will be the hallmarks of this year's GPRS phones.

GPRS roaming can be realized in all places covered by GPRS in China, and no roaming charges will be added to the user roaming. In the absence of GPRS network time GPRS phones can still be used, you can make normal calls and CSD mode data business, but GPRS business can not be used.
7. How do I switch between GPRS and the original CSD (circuit switched) dialing method?
Before the data service (e.g., WAP), you need to select the connection method, either CSD dial-up or GPRS, and then you need to turn off the original service and select the connection method again. For example, if the user starts the WAP browser, the cell phone will pop up a menu for you to choose the connection method (or default connection settings), such as GPRS, then the user will browse all kinds of information, games, etc., through GPRS, and the user wants to switch to dial-up access to the WAP, you need to roll out the WAP browser, select the connection method as dial-up, and then start the WAP browser to switch to dial-up (CSD) mode of the WAP. （
