The use of Network based Migrating User Agents for Personal Communication Services

Proposes the use of a network-based agent that represents mobile users in a personal communication services (PCS) environment. The agent, called a user process, performs all the complex signalling functions on behalf of the mobile terminal, thus reducing the amount of signalling traffic that must travel over the valuable air interface. To achieve low call establishment delays, we propose migrating the user process as the mobile terminal moves. We examine three process migration techniques and determine the one mechanism that is most suited to our needs.
