    摘要: The invention manifests a secure, on-demand meet-me conferencing service embodied within a telephone network having an advanced intelligent network (AIN) infrastructure. Centralized control from a service control point of provisioned conferencing bridges located in network switches is effected in the AIN telephone network, thereby overcoming the resource efficiency limitations and corresponding costs of the prior art systems. In addition, it enables the local exchange carrier (LEC) to offer of a new type of conferencing service at a lower cost where prior reservation of conferencing facilities is no longer necessary and which possesses other advantages with respect to ease of use, ease of administration, availability and security. Users of the service first subscribe to it, and then utilize paired primary and secondary authorization codes to access a conference.

    摘要: A fraud detection system is disclosed for telephone PBX calls. The system includes a fraud data server for buffering the call detail records relating to inbound 800 number calls and outbound international calls. A threshold manager is connected at its input to an output of the fraud data server for detecting numerical counts exceeding preselected threshold values, in predetermined fields of the call detail records, and generates an alarm. The output of the threshold manager is connected to an input of the fraud data server for buffering the alarm incident to respective call detail records. A computer workstation is connected to the fraud data server for receiving packets of call detail records relating to alarm data, in a filtered preselected format. The workstation includes a monitor for displaying the alarm data on a graphical interface.

    摘要: Un site de base (300) d'un système de transmission reçoit un signal (400) représentant une demande émanant d'une unité de transmission (200) pour accéder au système de transmission (100). Ce signal renferme un code d'identification (402) et un autre code qui indique le moment où l'unité de transmission a été autorisée à accéder au système de transmission (100). Le site de base (300) traite le code d'identification (402) pour déterminer initialement que l'unité de transmission (200) ne doit pas être autorisée à accéder au système de transmission (100). En outre, l'autre code (410) est traité pour déterminer si l'unité de transmission (200) a été autorisée à accéder au système de transmission (100) dans un certain intervalle de temps. Dans l'affirmative, l'unité de transmission (200) est autorisée à accéder au système de transmission.
