ANSWER 1.
Business Infrastructures
New stakeholders have been identified within the business infrastructure context. These are:

• Virtual network operators
• Sensor network manufacturers
• Sensor network connectivity operators
• Mobile and ad hoc network operators
• Customer care support centres
• Security (e.g. certification, key distribution) authorities and guarantors
• Regulatory bodies for unlicensed spectrum harmonisation
• IPR related industry and community

In particular it was identified in the SRA, that mobility and mobile e-commerce will require radically faster processes for setting up new business relationships. Time-to-market for a new type or instance of a value network must be cut down. This requires a streamlined approach for taking into account e.g. automated service provider discovery, negotiation processes and contracting, as well as adoption of micro-payments and streamlined pricing.

Final Objective; consolidating and disseminating business architectures and modelling practices that allow a quick pre-estimation of the business viability and sustainability that can result from a novel enabling technology. Such practices could prove extremely useful if implemented in IST across a wide range of projects.

User Services
The user's communication environment is generally composed of various terminals that may vary (e.g. PDA, laptop, PC) depending on the user's context (e.g. home, work, leisure, vacation, static or roaming). The communication and computation capability of this communication environment is increasing, enabling the emergence of a new brand of innovative mobile services.

A new brand of really innovative user services are expected to emerge due to the available bandwidth and the variety of contexts in which they can be used. Moreover they are expected to answer realistic user's expectations.

The new innovative mobile user services will have to be intelligent enough to:

• Understand the total situation or context attached to a person (or a group of persons)
• Behave accordingly either reactively (meaning that a context change has been detected and that the service adapts accordingly its behaviour) or pro-actively (the service detecting in advance something the user is not aware of and proposes to adapt its behaviour accordingly).
• Optimally exploit the communication capabilities available at the user side
• Be easy to use

This domain of mobilie intelligence offers a wide landscape of new possibilities driven both by new mobile equipment capabilities (e.g. sensors, connectivity, multi-media support) and new related usages.

Service Execution Environment.
The Service Execution Environment enables discovery, selection, mediation, invocation and interoperation of Services. This includes establishing a conceptual model, defining its execution semantics, developing the architecture of the system and designing the software.

The environment will provide execution semantics, mediation, discovery and invocation mechanisms, and any other functionality needed in the context of executing mobile services.

It is an execution environment for business application integration where enhanced mobile services are integrated for various business applications. The aim is to increase business processes automation in a very flexible manner while providing scalable integration solutions.

In terms of innovation for mobile services and service architecture, the objective is to bring it to reality and to take advantage of the progress achieved in parallel in other domains such as radio and networks infrastructure, in order to contribute to a wide adoption of the mobile services, as well as, the fixed ones seamlessly. To achieve these goals, all the players in the mobile communications field have to make progress in the area of service architecture. The objective is to remove the hurdles which prevent the adoption of mobile services.
