General Packet Radio Service ( GPRS) is a service on the and system's (GSM). GPRS was originally standardized by (ETSI) in response to the earlier and packet-switched cellular technologies.

It is now maintained by the (3GPP). GPRS usage is typically charged based on volume of data transferred, contrasting with data, which is usually billed per minute of connection time.

Sometimes billing time is broken down to every third of a minute. Usage above the is charged per megabyte, speed limited, or disallowed.

GPRS is a service, implying variable and that depend on the number of other users sharing the service concurrently, as opposed to, where a certain (QoS) is guaranteed during the connection. In 2G systems, GPRS provides data rates of 56–114 kbit/second. Cellular technology combined with GPRS is sometimes described as, that is, a technology between the second () and third () generations of mobile telephony.

It provides moderate-speed data transfer, by using unused (TDMA) channels in, for example, the GSM system. GPRS is integrated into GSM Release 97 and newer releases. See also: The GPRS core network allows, and to transmit packets to external networks such as the. The GPRS system is an integrated part of the. Services offered [ ] GPRS extends the GSM Packet circuit switched data capabilities and makes the following services possible: • messaging and broadcasting • 'Always on' internet access • (MMS) • over cellular (PoC) • and presence— • Internet applications for smart devices through (WAP) • (P2P) service: inter-networking with the Internet (IP) • (P2M) service [ ]: point-to-multipoint multicast and point-to-multipoint group calls If SMS over GPRS is used, an SMS transmission speed of about 30 SMS messages per minute may be achieved. This is much faster than using the ordinary SMS over GSM, whose SMS transmission speed is about 6 to 10 SMS messages per minute.

Protocols supported [ ] GPRS supports the following protocols: • (IP). In practice, built-in use since was not yet popular. Safeip Pro Full Cracked Apk there.

In this mode, PPP is often not supported by the but if the mobile is used as a modem to the connected computer, PPP is used to tunnel IP to the phone. This allows an IP address to be assigned dynamically ( not ) to the mobile equipment. • connections. This is typically used for applications like wireless payment terminals, although it has been removed from the standard.

X.25 can still be supported over PPP, or even over IP, but doing this requires either a network-based to perform encapsulation or intelligence built into the end-device/terminal; e.g., user equipment (UE). When is used, each phone can have one or more allocated. GPRS will store and forward the IP packets to the phone even during.

The TCP handles any packet loss (e.g. Cmi9880 Driver on this page. Due to a radio noise induced pause). Hardware [ ] Devices supporting GPRS are divided into three classes: Class A Can be connected to GPRS service and GSM service (voice, SMS), using both at the same time. Such devices are known to be available today. Class B Can be connected to GPRS service and GSM service (voice, SMS), but using only one or the other at a given time. During GSM service (voice call or SMS), GPRS service is suspended, and then resumed automatically after the GSM service (voice call or SMS) has concluded. Most GPRS mobile devices are Class B.

Class C Are connected to either GPRS service or GSM service (voice, SMS). Must be switched manually between one and the other service. A true Class A device may be required to transmit on two different frequencies at the same time, and thus will need two radios. To get around this expensive requirement, a GPRS mobile may implement the feature. A DTM-capable mobile may use simultaneous voice and packet data, with the network coordinating to ensure that it is not required to transmit on two different frequencies at the same time. Such mobiles are considered pseudo-Class A, sometimes referred to as 'simple class A'.
