The Mobile Station Application Execution Environment (MExE) is a standard, which is aimed at smart mobile terminals and its purpose is to facilitate intelligent network services. It is a part of the Virtual Home Environment, the mobile extension of the Open Service Architecture. Before a mobile terminal (MT) can download MExE applications, it must transfer its Composite Capability / Preference Profile (CC/PP) description to a MExE server. This master thesis proposes strategies for the transfer of CC/PP descriptions to the MExE servers. The utilised research method is a constructive research method that is based on abstract analysis of written material of the studied subject. The CC/PP description may originate from multiple sources and there must be a clearly defined strategy for transferring it to the MExE server. A MT must be able to manage dynamically its resources in MExE. This thesis has three research problems: what should be the source of the MT's CC/PP description, what is a feasible CC/PP description transfer strategy for MTs and what are the dynamic resource management requirements of the mobile terminal? The proposed CC/PP strategy suggests fetching the CC/PP description in fragments from servers in the network and from the MT. This considerably improves the efficiency of CC/PP transfer in mobile networks. Changes to the capabilities of the MT can be transmitted when necessary to the MExE server. MExE satisfies the requirements defined by the thesis and it has potential to become a widely used standard. The following studies will concentrate on designing decision capabilities for a MExE server and a common resource vocabulary for MTs. The designed server will also support dynamic resource maintenance for MTs. A test environment will be constructed, which allows for a closer evaluation of present and future results.
