The era of fixed-mobile convergence is imminent, thanks to the Next Generation Network (NGN) paradigm. Such approaches encompass converged networks where users can use any kind of terminals and network access technologies.An utmost issue for NGN is to provide multimodal digital services, since the user’s terminal or network access are expected to change over time during his own session. This means services must be able to shift from one form of service delivery to another according to context updates. We propose to implement context awareness for digital services in NGNs by providing context-awareness to application servers hosted in a NGN. These services running on applications servers (AS) are consumed through a network using the client-server paradigm. In this situation, the context is composed of information about the network and features of the end-user terminal. We explain and implemente a novel architecture that makes AS taking into account the context-awareness of the digital service they host. The architecture employs application ontology in order to monitor the applications’ context. Moreover, when a new context-aware application is deployed on the application server, its context-logic (a set of SWRL rules which rely the domain ontology called context signature) is extracted from the application bundle. Each SWRL rule encodes a context-aware threshold for the application. When a rule is triggered at runtime, the application server notifies the application, so that the application change its service delivery modality, as the current context favors another service delivery modality different than the current one
