Regulatory issues for communications and value-added services determine a key requirement of study to ensure that a competitive and fair commercial usage within a legal domain can be achieved. Therefore, this paper pursues a comprehensive study identifying the key mobile grid regulations on a European level, while such grid services are considered to be of major importance for upcoming value-added services. The focus is put mainly on those regulatory determinations affecting areas neglected by the eCommunications framework, namely the areas of value-added services in mobile grids and of determinations governing relations among service providers and between service consumers and service providers. Thus, the major achievement here outlines the potential for open and unregulated mobile grid applications as well as services markets. Due to the lack of eCommunications determinations— as shown in a previous study —, this new work ensures the careful consideration of fundamental consumer rights and competition efficiency for value-added services.
