Abstract: The limitations of the current mobile device capabilities are analyzed followed with the description of a new proposed module for managing and provisioning mobile service based on grid-enabled and resource-limited devices. By taking advantages of grid computing and ubiquitous computing, mobile computing is integrated with OGSA(open grid service architecture )to manage the network server resources and resourcelimited mobile terminal dynamically and intelligently. It provides a mobile service managing and provisioning module that is QoS(quality of service)-ensured, peer-to-peer and transparent to users, which results in more extensibility and more powerful capability of service integration than the module for managing and provisioning traditional terminal-centric mobile service.
