Interworking 2G and 3G Networks

Ensuring seamless handover between 2G networks such as GSM and 3G networks such as UMTS will be vital if next generation cellular networks are to be rolled out successfully. This module explores many of the mobility management procedures that will need to be implemented to support effective 2G/3G interworking both in the Circuit Switched and Packet Switched domains. The paper focuses on the signalling required in order to facilitate interworking as well as issues regarding networks operating at different releases of the 3GPP specification, and how these shortfalls may be overcome.
