GPRS Terminology
This page on GPRS terminology describes terms related to GPRS standard. It covers what is GPRS, GPRS frame structure, SGSN, GGSN, TBF, TFI, EDGE, BEP, EDA, CS1 to CS4 gprs coding schemes, GPRS interfaces, MMS etc.
| GPRS Terms | Basic description | RF Wireless World Reference |
|---|---|---|
| What is GPRS | General packet radio service, the packet centric data communication standard for cellular technologies such as GSM and WCDMA. Mainly used in GSM. | what is GPRS |
| GPRS frame structure | The frame structure used between Base Station and GPRS compliant UE for communication and exchange of data as well as control informations. | GPRS frame |
| SGSN | Serving GPRS Support Node | SGSN in GPRS Network |
| GGSN | Gateway GPRS Support Node | GGSN in GPRS network |
| TBF | Temporary Block Flow | TBF function |
| TFI | Temporary Flow Identity | TFI function |
| EDGE | Enhanced Data rates for GSM Evolution | EDGE basics |
| BEP | Bit Error Probability | What is BEP |
| EDA | Extended Dynamic Allocation, the scheme by which subscriber(UE) can use for number of time slots in the uplink unlike DA(Dynamic Allocation) method. Here UE need to decode USF just once and can transmit the data over the time slots till the next block period. | EDA basics |
| CS1,CS2,CS3,CS4 | Coding scheme used in GPRS to facilitate different data rates for the UE. Different scheme supports different data rates. | GPRS coding schemes |
| GPRS Interfaces | The interfaces are the signal connections by which different GPRS network elements are interconnected. | GPRS Network Interfaces |
| MMS | Multimedia Message Service, the service by which bigger messages can be transmitted over GPRS network. | SMS vs MMS |
