Consequently, when a user has established a voice connection with another terminal and wants to access a service, he must first temporarily interrupt his connection, then establish a connection with the server so that he can activate said service. service at its disposal and finally reestablish the initial link with the other terminal. In addition, this prohibits dynamically offering the user, during a voice link with another user, services adapted to certain events that may occur during a call, such as a priority incoming call, a text message to display during call or a request for conference entry. In addition, only the services associated with the preprogrammed functions can be made available to terminal users. This arrangement therefore has a "static" character ill-suited to the requirements of real-time processing.
• 1 107523 consists first of all in establishing, in a transmission channel of the public network, dedicated to signaling, a link between a terminal wishing to access services of its private home network and a gateway connected to this private network, then have the calling terminal transmit, via the gateway, a page in WML language (for “Word Markup Language”) so as to offer its user a certain number of services.
