An access interface (Bai) allows access to a context-sensitive service to a user
portable set (Ui) according to a chosen geographical coverage. A mobile station
(SMi) distributed in the access interface area of coverage is equipped with communication
means to establish short-range radio frequency communication within a chosen perimeter.
The user portable set (Ui) is equipped with short-range radio frequency communication
means paired with those of the mobile station to establish the said short-range
radio frequency communication within the chosen perimeter. The user portable set
(Ui) communicates with the mobile station (SMi) and the access interface (Bai)
to access the said context-sensitive service (Si) which is adapted according to
the position and/or identity of the user.
