  • Patent number: 7590678
    Abstract: A method for determining a regime to be applied to a connection in a communication system by means of which connections may be made to terminals associated with any of a plurality of operators, each terminal being addressable by means of a subscriber identity formatted to include a first field and a second field, the first field being, for at least some of the subscriber identities indicative of the operator with which a respective subscriber identity is associated, the method comprising: transmitting to an operator determination function of the network a first message requesting a regime for a connection and including a subscriber identity field comprising an indication of the subscriber identity of the terminal that is to terminate the connection; receiving the first message at the operator determination function; determining by means of the operator determination function the operator to which the subscriber identity of the terminal that is to terminate the connection is assigned, and content of the first

  • Patent number: 6978005
    Abstract: The invention relates to a method for implementing a service in a digital multiple-service network comprising an exchange, a first telecommunication terminal connected to the multiple-service network via a first interface and a second telecommunication terminal connected to the multiple-service network via a second interface. In the method, the service is implemented using a server connected to the multiple-service network via a third interface, and the service information is transmitted to the second telecommunication terminal using channels reserved for signalling and a signalling protocol between the terminals and the exchange and between exchanges that comprises a limited amount of information not belonging to the call.

  • Patent number: 6567501
    Abstract: A method for transferring alarms, in which method a pre-determined area (1) is monitored by a monitoring device (24) connected to a subscriber line (10, 12, 14); the condition of the subscriber line (10, 12, 14) is monitored by line testing; when the ISDN subscriber line (10, 12, 14) lacks functionality an alarm is identified in a switching center (20); and from the switching center (20) the alarm is directed to an alarm monitoring system.
