A communication system comprises a fixed communication network (N1) connected to a NGN network (N2) provided with a media gateway controller (M1) and a media gateway (M2), and user equipments (UE) connected to the fixed communication network (N1) or NGN network (N2). This NGN network (N2) further comprises a media server (M3) connected to the media gateway controller (M1) and arranged for generating information service messages designated by message identifiers. The system also comprises a service control device (D) arranged, when it is triggered with a chosen broadcast identifier corresponding to a group of user equipments (UE) and to a message identifier, to determine the corresponding group, then to provide the media server (M3) with the message identifier and initiate the establishment of communications between the media server (M3) and each user equipment (UE) of the determined group in order the information service message corresponding to the message identifier be selectively transmitted from the media server (M3) to each user equipment (UE) of the determined group through at least the media gateway controller (M1).
