GPRS system architecture

GPRS full form provides many devices without restricting data rates of transmission. The service precedence namely high, low, normal, class, reliability throughput and delay are determined by QoS profile.

GPRS uses GSM architecture for voice. In order to offer packet data services through GPRS, a new class of network node needs to be introduced as an upgrade to the existing GSM network.

The network nodes are called GPRS support nodes ( GNN ). The GPRS support nodes are responsible for the delivery and routing of data packet between the mobile stations and the external packet data network ( PDN ).
