Downloadable Mobile Value-Added-Services through Software Radio and Switching Integrated Platforms


The objective of MOBIVAS is to define, design, develop and validate an integrated application architecture for downloadable Software Defined Radio (SDR) Value-Added-Services (VAS).

The activities will be to:
- Assess a framework for downloadable value added services over different network environments.
- Design and implement a framework to provide efficient management of network resources.
- Design and develop of mechanisms to allow reliable and seamless switching between different wireless/mobile bearer technologies considering the emerging software defined radio technology.
- Specify and implement an integrated software infrastructure on the application layer for enabling means of downloading new, value added application layer services from a VAS Providers' network, interconnected to an Operator, to the end-user mobile stations.
- Develop a framework for charging and billing schemes
- Integrate modules for an experimental platform for trial support, verify, demonstrate the benefits and synergy of the protect outcomes in a field trial and contribute to the relevant standardisation bodies.

The overall objective of MOBIVAS is to develop architectural approaches and prototypical implementations of integrated software platforms and systems, adaptable to different network services and technologies, which will open new opportunities for advanced Value Added Service Providers (VASPs). A key objective of MOBIVAS is to develop innovative and modular network components for the seamless and efficient service provision in converging existing network technologies by combining new wireless technologies with TINA/CORBA principles, by applying sophisticated mechanisms in order to support a required Quality of Service and by introducing novel methods for developing innovative network elements while integrating existing technologies, such as GSM, DECT, Wireless LANs with upcoming ones such as GPRS, UMTS.

Work description:
The proposed software defined radio value added service infrastructure can be looked at from three points of views: functional, operational and architectural. By functional we mean the high level features that the "software defined radio" value added services need. The operational components are the business-dependent operations. The architectural component addresses technological issues. The proposed functional elements cater for open service provision. The evolution of multimedia applications over mobile networks imposes the provision of adaptive services. The services will be able to operate in dynamic usage conditions while maintaining the highest possible level of quality. The generic architecture and functional scheme is illustrated in the figure below. A proposed intelligent service initiation and synthesis environment, based on basic reusable and extendible protocol and services components, enabling the flexible introduction of services and VAS component distribution, will be provided through an open modelling and communication environment.
The proposed scheme will result in an integrated application architecture for downloadable "software defined radio" Value Added Services (VAS) and the introduction of an open, integrated Switching and Network Access architecture and application platform for the support of "software defined radio" features. Generic interfaces for, e.g. the interaction of radio independent and programmable radio dependent parts, as well as a "service negotiation" procedure will be introduced for the configuration of the programmable radio dependent parts. The introduced platforms and components will provide intelligence available in a formal and generic way for open service architecture and control, coping with the complexity and requirements of future wireless infrastructure for the provision of adaptable radio schemes and seamless services. On the operational side, a one-stop charging and accounting model for value added services provided by independent contracted VASPs through an operator's network will be provided to the end-user thus eliminating a lot of administrative overhead for the VASP and simplifying the overall usage of multiple VAS by the end user without requiring separate contract agreements and billing with each VASP. The dynamic introduction of new data services into the network will enrich the operator's product offerings with minimal administrative overhead and additionally will be able to discover new revenue streams from sources other than pure traffic (e.g. one-stop billing for VASPs, share of end-user transactions). The choice of the technology support to develop MOBIVAS platform functionality and meet its various requirements depends, in part, on the constraints and limits (e.g. power processing, memory) imposed by the terminal. The development support should provide facilities for communication security needs, as well as for software downloading. Another important aspect in the choice of the technology support is openness, which makes it easy for software engineers to develop new services using standard languages and tools; it also makes it easy for service providers to integrate new services in the VAS platform and to prevent interoperability problems. Two possible candidates for the technology platform: CORBA and JAVA based mobile-agents. CORBA is a standard of the OMG (Object Management Group). In exploring the JAVA mobile agent solution we will seek standard solutions such as MASIF (Mobile Agent System Interoperability Facility). MASIF is a proposal from OMG to add mobile agent interoperability facilities to CORBA. The use of standard solutions, whenever adequate and possible, will lead us to build an open platform.

Key Issues
- Software download capabilities of the terminal
- Capabilities for transparent dynamic download of transport-oriented protocols
- Flexibility in Provisioning and Accessing services
- Registration of services
- Authentication, Security, Accounting/Billing
- Service and user Mobility

Expected Impact
The contribution of MOBIVAS is the enabling of various VASPs to provide VASs to mobile users. The design of such an integrated environment involves the introduction an interconnection of VASPs via a VASP Network infrastructure, the development of Operator's infrastructure to support a network of VASPs with increased demands on priority and dynamic aspects. Moreover, the Operator's Platform and Software environment will introduce advanced, flexible and dynamic (in terms of IP flows) accounting/billing procedures. The Intelligent Base Station will be designed to cope with the very demanding tasks of terminal classification negotiation, download of Look-up service, service negotiation and fast download of necessary service elements. The mobile user will be transparently connected to available VASPs according to the type of terminal, location, access network.
