Abstract

The multi-system terminal determines whether to adapt a service being provided based on context information including a plurality of access network state information, user profile information, and a pre-registered service adaptation policy. The service is adapted according to the context information, and the adapted service is provided to the user. In this case, when a network change to which multiple system terminals are connected is required, the network may be selectively connected. By doing so, it is possible to provide an optimal service that satisfies the user's surroundings and service requirements, and minimizes the deterioration of the service since the optimal connection of the optimal network is made from the adapted service.
