Here are the results for GPRS

1G

The first generation of analogue mobile phone technologies including AMPS, TACS and NMT

2.5G

The enhancement of GSM which includes technologies such as GPRS

2G

The second generation of digital mobile phone technologies including GSM, CDMA IS-95 and D-AMPS IS-136

3G

The third generation of mobile phone technologies covered by the ITU IMT-2000 family

3GPP

The 3rd Generation Partnership Project, a grouping of international standards bodies, operators and vendors with the responsibility of standardising the WCDMA based members of the IMT-2000 family

3GPP2

The counterpart of 3GPP with responsibility for standardising the CDMA2000-based members of the IMT-2000 family. 3GPP2 is spearheaded by ANSI

8PSK

Octantal Phase Shift Keying

EDGE

Enhanced Data rates for GSM Evolution; effectively the final stage in the evolution of the GSM standard, EDGE uses a new modulation schema to enable theoretical data speeds of up to 384kbit/s within the existing GSM spectrum. An alternative upgrade path towards 3G services for operators, such as those in the USA, without access to new spectrum. Also known as Enhanced GPRS (E-GPRS)

FSS

Fixed Satellite ServiceGb The interface between the PCU and the SGSN in a GSM/GPRS network

Gc

The interface between the GGSN and the HLR in a GSM/GPRS network

Gd

The interface between the SGSN and the SMSC in a GSM/GPRS network

Gf

The interface between the SGSN and the EIR in a GSM/GPRS network

GGSN

Gateway GPRS Support Node; the gateway between a cellular network and a IP network.

Gi

The interface between the GGSN and the Internet in a GPRS network

Gn

The interface between the GGSN and the SGSN in a GPRS network

Gp

The interfaces between the GGSN/SGSN and the Border Gateway in a GPRS network

GPRS

General Packet Radio Service; standardised as part of GSM Phase 2+, GPRS represents the first implementation of packet switching within GSM, which is a circuit switched technology. GPRS offers theoretical data speeds of up to 115kbit/s using multislot techniques. GPRS is an essential precursor for 3G as it introduces the packet switched core required for UMTS

Gr

The interface between the SGSN and the HLR in a GPRS network

GRX

GPRS Roaming Exchange

Gs

The interface between the SGSN and the MSC in a GSM/GPRS network

I-mode

A service developed by Japanese operator NTT DoCoMo, I-mode delivers a huge range of services to subscribers and has proved enormously popular with some 30 million regular users. The revenue sharing model used for I-mode is being adopted by other operators as the basis for the new services enabled by GPRS and 3G

Iucs

The connection between the RNC and the circuit switched network in a GSM/GPRS/UMTS network

Iups

The connection between the RNC and the packet switched network in a GSM/GPRS/UMTS network

PCU

Packet Control Unit; an element in a GPRS/UMTS network

SGSN

Serving GPRS Support Node; the gateway between the RNC and the core network in a GPRS/UMTS network
