Part A
Compare and contrast the system architectures of GSM and GPRS.
Answer
GSM is a circuit-switched architecture designed primarily for voice communication using dedicated channels. In contrast, GPRS is a packet-switched overlay on the GSM network that introduces the SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node) to handle data packets, enabling always-on connectivity and efficient resource utilization for data services.
Demonstrate the process of handover in mobile communications.
Answer
Handover is the process of transferring an ongoing call or data session from one base station to another as a mobile station moves. It involves: 1) Initiation, where the mobile or network detects signal degradation; 2) Resource reservation at the target base station; 3) Execution, where the connection is switched; and 4) Completion, where the old connection is released.
