MExE provides a standardized execution environment within the UE, and enables the negotiation of capabilities with the MExE service provider. This paper describes the types of service that can typically be delivered using MExE and the architecture of the MExE environment. It then goes on to discuss how MExE services may be accessed such as remote service access or application download. Finally the concepts of MExE and UE classmarks are discussed along with an overview of MExE Classmarks 1, 2 and 3. ....etc
