Service program mobility architecture

The delivery of mobile services is traditionally limited to the cellular operator's home domain, except for a small set of standardized services. Due to the centralized nature of service platforms, resource demanding services suffer from long delays if a user is accessing them when roaming. In this paper we describe an architecture that supports a dynamic, distributed service provisioning for mobile users. Both optimized service placement within an operator's network and placement of service components in a foreign network are supported. This leads to both more efficient resource usage and better quality for the users.
