Abstract: A flexible, extensile, and dynamically configurable back-end Application Server environment that efficiently supports the ever-increasing range of activities for which mobile subscribers employ their wireless devices. The environment may operate within any number of entities within a messaging ecosystem including for example a service provider.

Abstract: Leveraging the ubiquitous nature of wireless devices and the popularity of (Short Message Service, Multimedia Message Service, etc.) messaging, an infrastructure that supports message-based conversations (with for example the maintenance or preservation of state, context, etc. across or during the message exchanges) allowing users of wireless devices to employ their wireless devices to engage in and complete increasingly more complicated activities. The infrastructure may optionally leverage the capabilities of a centrally-located Messaging Inter-Carrier Vendor.
