Mobile agent platforms and systems Advanced service provisioning allows for rapid, cost-effective service deployment. Modern mobile telecommunications evolve towards value-added, on-demand services in which the need for communication becomes frequent and ongoing, and the nature of the communication becomes more complex. The services of the future will be available ‘a la carte’, allowing subscribers to receive content and applications when they want it. | Mobile Telecommunications Protocols For Data Networks.

Modern mobile telecommunications evolve towards value-added on-demand services in which the need for communication becomes frequent and ongoing and the nature of the communication becomes more complex. The services of the future will be available a la carte allowing subscribers to receive content and applications when they want it. Introducing Mobile Agents MAs within the network devices Mobile Stations MSs and Mobile Switching Centers MSCs provides the necessary flexibility into the network and enhanced service delivery. MAs enable on-demand provision of customized services via dynamic agent downloading from the provider system to the customer system or directly to the network resources. MAs have the capability to migrate between networks to customize for the network and to decentralize service control and management software by bringing control and managements agents as close as possible to the resources. MAs can be used in mobile networks to support advanced service provisioning as well as for personal communication for mobility and to support Virtual Home Environment VHE . The VHE agent enables individually subscribed and customized services to follow their associated users to wherever they roam. 1.1 MOBILE AGENT PLATFORMS Mobile Agent Technology MAT uses interworking between Mobile Agent Platforms MAPs . Several MAPs are based on Java. These platforms are Grasshopper Aglets Concordia Voyager and Odyssey. Each MAP has a class library that allows the user to develop agents and applications. The core abstractions are common to most platforms since they are inherent in the MA paradigm. These abstractions include agents hosts entry points and proxies. 2 MOBILE AGENT PLATFORMS AND SYSTEMS Agents In each platform a base class .
