A specific module of a communications network comprises (i) first and second telephone interface mechanisms respectively connected to telephone channels, (ii) interconnection mechanisms between these first and second interfaces, and (iii) a processing mechanism. In response to a request for a telephone call from a telephone set calling a call (dialing) number assigned to a portable handset, the call request being received at one of the first interfaces, an attempt is made to establish, in addition to the first telephone connection from the calling set to said first telephone interface, a second telephone connection from the portable handset to one of the second telephone interfaces in accordance with predetermined conditions, and the interconnection of the first and second interfaces concerned is obtained.

Device and method for telephone interconnections for a communications

In a communications network between fixed stations and fixed terminals, the said fixed stations being linked to the telephony channels while the fixed terminals include an antenna for mutual interaction over distance with independent stations, connection means to the telephony channels of the network are provided, and there is established a telephony relationship between an independent station and another station linked to the telephony channels of the network, by an intermediary of a primary link between the independent station and the connection means, via antennas of a primary fixed terminal. A secondary fixed terminal is chosen on the basis of predetermined selection criteria, and a secondary link is established between the independent station (SA) and the connection means, via an antenna of the secondary fixed terminal. In response to a predetermined station condition, relating to the primary link, a predetermined request information item is generated from the independent station and, in response to reception of the request information item, the said relationship is switched so that it passes through this secondary link.
