GPRS application

1.GPRS of WAP application
WAP and GPRS is a combination of current orders, "Internet phone" to a new level of the best implementation of the program: GPRS is a powerful underlying transport, WAP is a high-level applications, if the WAP as a speeding vehicle, then GPRS is wide open for high-speed Road, you any information in the wireless world of surf at random.
2. Equipment
In addition to the GPRS cellular phone can be a variety of devices other than the reality, including the laptop computer PCMCIA modem, personal digital assistants and the extension of the hand-held computer. At present, the popular E-mail portable device BlackBerry (BlackBerry) manufacturer Research in Motion (RIM) in a Microcell Telecommunications known as the GSM providers to study how the other for GPRS wireless system to send messages.
3.GPRS business applications
Since the first text messaging, wireless data applications has gone through a leap of growth, just look at the well-known European and American manufacturers publicized General Packet Radio Service (GPRS) of thrust seems to be able to feel the next generation of mobile Data applications will be the advent of the era. 99 will be the end or early in 2000 to open the General Packet Radio Service GPRS, into a third-generation personal multimedia services an important milestone will enable mobile communications and data networks together so that the IP business to the introduction of a broad mobile market . Although the use of mobile data is a relatively small, but in some markets, the different user groups are being developed rapidly, its main driving force in the area of mobile data services used in the commercial market. Whether Ericsson, Nokia or Alcatel, almost all of the publicity GPRS manufacturers are business users of the fast-growing market to persuade the operator.
GSM system for mobile data communications division (that is, GPRS) is the basic packet radio service, using packet switching the way, the data rate of up to 164kb /, it can be to provide GSM mobile environment, high-speed data business, but also Transceiver to provide Emai1, Internet access features such cases.
4.GPRS function of the corresponding business applications
GPRS is a new GSM data services, which can give mobile users with wireless data packet access Services Unit. GPRS is a remote and mobile users in the data network (such as support for the TCP / IP, X.25 network, and so on) to provide a connection between so as to provide users with high-speed mobile wireless IP and wireless business X.25.
Using GPRS packet switching technology, which allows multiple users to share some of the fixed channel resources. If the air interface on the TDMA frame of 8 slots are used to transmit data, the data rate of up to 164kb/8.GSM air interface channel resources can be occupied by voice, GPRS data services can be occupied. Of course, in the channel adequate conditions, can channel some of the definition of GPRS dedicated channel.
To achieve the GPRS network, the need for the traditional GSM network, the introduction of a new network interface and communication protocols. At present, the introduction of GPRS network GSN (GPRS SurportingNode) node. Taiwan Mobile will be GPRS mobile station or GPRS / GSM dual-mode mobile station.
