The invention relates to the provision of services. According to the invention, a service session supervision platform ( 10 ) is disposed between an access network ( 1 ) and an input node ( 12 ) of a service-hosting network. During the provision of a service, at least one atomic section is first defined, said section consisting of a determined sequence of events which are involved in message exchanges with a subscriber. The supervision platform detects and flags events forming the beginning or end of an atomic section in a service session in progress for a subscriber by means of the access network. A communication interrupt request from a subscriber is processed by ascertaining if an atomic section is in progress for said subscriber according to the atomic section beginnings and ends flagged by the supervision platform, in order to determine whether or not the communication must be interrupted immediately.
