GPRS was established by the European Telecommunications Standards Institute (ETSI) in response to earlier CDPD and I-mode packet-switched cellular technology.
1.GPRS(General Packet Radio Service) is a packet-oriented mobile data standard for mobile communications (GSM) on a global system of 2G and 2.3G cellular communications networks. It is now maintained by the 3rd Generation Partnership Project (3GPP).
3. General packet radio service (GPRS) provides data rates of 56–114 kb/sec.
4.GPRS requires major changes in the network infrastructure. In addition to the current GSM entities, several new network elements have been introduced to create end-to-end packet transfer modes. The HLR is enhanced with the GPRS customer information of every MS.
5. A GPRS network may use multiple serving nodes but only one gateway node is required to connect to an external network (ie, the Internet).
6. 2G cellular technology combined with GPRS (general packet radio service) is sometimes described as 2.5G, that is, a technology between generations of the second (2G) and third (3G) mobile telephony.
History of GPRS
1.GPRS evolved into a packet-switched data service in 2000, connected to the channel-switched cellular radio network GSM.
2.GPRS (General Packet Radio Service) extends fixed Internet access by connecting mobile terminals worldwide.
3. The CELL PACK protocol developed 1991-1993 was the trigger point for starting in 1993 specification of standard GPRS by ETSI SMG.
Benefits of GPRS
- It provides higher data transfer speeds than a fixed telecommunications network. Its optimum speed is 171.2 kbps, which is almost three times faster than fixed-telecommunications speed.
- It has new and better applications.
- It provides internet applications on mobile and also facilitates web browsing, messaging, e-commerce, etc.
- GPRS provides instant connection and instant data transfer.
- It is a very cost-effective protocol.
Characteristics of General packet Radio Service(GPRS)
- SMS service: bearer for SMS
- Point-to-point (PTP) service: internetworking with the Internet (IP protocols) and X.25 networks.
- Point-to-multipoint (PTM) service: point-to-multipoint multicast and point-to-multipoint group calls.
- Future enhancements: flexible to add new functions, such as more capacity, more users, new accesses, new protocols, new radio networks.
- GPRS (General Packet Radio Service) supports standard data network protocol (TCP / IP, X.25) based applications, such as www, FTP, telnet, email, video, audio for wireless PCs, or mobile offices.
- GPRS are also specific protocol based applications, e.g. Point-to-point application (toll road system, UIC train control system, etc.) and point-to-multipoint application (weather information, road traffic information, news, fleet management).
- Session Management
- Routing(Data Transmission)
- Mobility management
why is needed for GPRS?
- Voice messages as well as text, audio, video transmission.
- A SIM card with GPRS service.
