GPRS & GSM Architecture. In this video taken from our GSM & GPRS System Engineering course, our four focus areas are: The Mobile Phone & Subscriber Identity Module, The GSM / Edge Radio Access Network, Supporting Voice with the Circuit Switched Core Network and finally, Delivering Data with the Packet Switched Core Network. Our course explores the network architecture for both circuit and packet switched services, detailing the air interface and the initial procedures required for network access. Network usage is also explained, showing how calls, texts and data sessions are established and maintained as the subscriber moves around the network.
