  • Method of controlling a broadcast call
    Patent number: 8787959
    Abstract: The invention concerns a method of controlling a broadcast call in a telecommunications network (30) and a broadcast call control system (2). The telecommunications network (30) comprises switching units (214 to 220) for providing telephone connections to subscribers (221 to 230) of the telecommunications network (30). First, a broadcast call is triggered by one of one or more trigger servers (210, 211, 2101 to 2151) of a broadcast call control system (2) operating in parallel to the telecommunications network (30). This includes specifying data identifying a group of subscribers (221 to 230) of the telecommunications network (30) to be reached by the broadcast call and an announcement to be made to the group of subscribers (221 to 230) in the broadcast call. Then, a connection setup to each subscriber of the group of subscribers (221 to 230) in a cascade is requested and the announcement is replayed to each subscriber (221 to 230) a connection has been established to.
