摘要

An access interface (Bai) provides access to a contextual service at a user portable station (Ui) in accordance with a selected geographical coverage. A distributed mobile station (SMi) in the access interface coverage zone is equipped with communication means for setting up a short-range radiofrequency communication inside a selected perimeter. The user portable station (Ui) is equipped with short-range radiofrequency communication means combined with those of the mobile station to set up said short-range radiofrequency communication inside the selected perimeter. The user portable station (Ui) communicates with the mobile station (SMi) and the access interface (Bai) for accessing said contextual service (Si) which is adapted in accordance with the position and/or identity.
