Abstract: A method and system for minimizing database overhead associated with AIN services includes a cascaded database structure having at least two databases. The first database is a seed database containing basic information about the subscriber and his available services. The second database is a real-time database containing additional information that will be used by the appropriate service application. When the subscriber initially requests the service, the service management system creates an entry in the seed database for the subscriber. The entry contains an identifier for the subscriber and an identifier for the service. Until the subscriber actually uses the service, the seed database remains the only entry for the subscriber. When the subscriber actually uses the service, the service application reads the seed database to determine the privileges for the subscriber and creates a larger entry in the real-time database. The service application may not write to the seed database.

Abstract: The invention relates to a method for processing call signalling messages during a communications switch overload condition. The method integral to the invention comprises a dual threshold test, one based on message latency and the other based on queue occupancy. The method begins with the receipt of a plurality of call signalling messages comprising dispensable, indispensable and essential messages. The processing then continues by comparing a new message expected latency with a latency-based threshold. If the new message expected latency compares unfavourably, the queue occupancy is then compared with a queue occupancy based threshold. If this comparison is also unfavourable the call signalling messages are processed based on call type. Using the expected latency as a threshold ensures that no dispensable message has a latency greater than a tunable threshold.

Abstract: In a telecommunications network, a communication channel identifier agent (CCIA) is employed to identify communication channels. The CCIA directs the ISUP layer residing on a node to create Interface Identifiers (IntfIDs). The IntfIDs may contain an originating point code and a network identifier. The IntfIDs allow a node to use more than one originating point code to identify itself to other nodes in the telecommunications network. The IntfIDs are combined with circuit identification codes to identify communication channels between nodes in the telecommunications network.

Abstract: A system and method to connect a caller to a callee through the services of an operator, the method comprising: connecting the caller to the operator through an origination switch; connecting the operator to the callee through a destination switch; sending a release message to the destination switch with a request for a callee address; receiving the address at the operator; sending a release message to the origination switch with the callee address; and connecting the callee with the caller by utilizing the callee address. The method can also include putting the callee on hold at the destination switch and sending the callee address from the destination switch. The method can also include putting the caller on hold at the origination switch while receiving the callee address from the operator.

Abstract: When a subscriber calls into its Internet Service Provider (ISP), a central office receiving the call is triggered to perform a Local Number Portability (LNP) query. This LNP query is sent to an Intelligent Traffic Routing and Control (INTRAC) unit resident on a Service Control Point (SCP) which determines whether the call is to an ISP. If the call is to an ISP, the INTRAC unit polls a Remote Authentication Dial-In User Service (RADIUS) server to determine whether resources are available. The RADIUS server tracks the resources of the ISP and of other ISPs and informs the SCP of the available resources. The SCP then inserts the Local Routing Number (LRN) of the preferred resource into a reply that is sent to the central office. If resources are not available, the call is terminated before signaling occurs with any switch associated with the ISP. On the other hand, when resources are available, the subscriber can be directed to the preferred resource for the subscriber.

Abstract: A multiple point code routing node is configured to recognize multiple point codes as true point codes. The multiple point code routing node originates, terminates, and processes messages having any of its any of its true point codes. As a result, the multiple point code routing node can replace two or more signal transfer points in a conventional telecommunications network without requiring reconfiguration of other nodes in the telecommunications network. Multiple point code routing node may also recognize multiple adjacent point codes or secondary adjacent point codes of a mated multiple point code routing node. Because the multiple point code routing node can associate multiple point codes with its mate, the number of logical or physical signaling links between adjacent multiple point code routing nodes can be increased.

Abstract: A privacy screening service in an Advanced Intelligent Network (AIN) includes a service node which records a caller's name when a call directed to a subscriber of the service originates at an unknown number. The service node, in turn, places a call to the subscriber and transmits the recorded name together with a signal which is recognizable by a voice mail system. Following the transmission, the service node waits for the subscriber either to accept or reject a call from the caller. When the subscriber's line is answered by a voice mail system, the voice mail system recognizes and acknowledges the signal so that the voice mail system and service node may determine that their call is between two machines and may take appropriate action. One such action is to connect the caller to the subscriber's voice mail and to restart the subscriber's outgoing voice mail greeting.

Abstract: A method and apparatus for establishing a connection from a calling A-subscriber to a called B-subscriber in a telecommunications TC network that offers IN (=Intelligent Network) services, in particular in a multi-operator environment with IN-supported telephone number portability, is characterized in that upon determination of the target address of the called B-subscriber, a service requested for the current call by the calling A-subscriber is simultaneously compared to a stored service profile of the called B-subscriber and in the event of a determined incompatibility, a corresponding negative release message is sent to the calling A-subscriber. This permits the calling A-subscriber, before a possibly pointless connection is made to a called B-subscriber, who does not offer the services desired by the A-subscriber at all, to not even make the connection in the first place, which would be pointless for the calling A-subscriber.
