Abstract:
The present invention concerns an interconnect device (3) and process for connecting a first network (1) to a second network (2), comprising first connecting means (4) for connecting the interconnect device (3) to the first network (1), second connecting means (5) for connecting the interconnect device (3) to the second network (2), the second connecting means (5) being connected to the first connecting means (4). The first connecting means (4) and second connecting means (5) are intended to permit a communication between a first terminal (T1) located on the first network (1) and a second terminal (T2) located on the second network (2). The interconnect device (3) detects a voice communication termination by the second terminal (T2). If the voice communication has been initialized by the first terminal (T1), it starts a delaying period for delaying the sending of an indication of the termination to the first terminal (T1) for allowing a terminal located on the second network (2) to resume the voice communication before the end of the delaying period.
Abstract:

In a preferred embodiment the calls include both connection-oriented switched telephony (COST) calls (13) and Data Network Telephony (DNT) calls (12). Callers are enabled to leave voice mails as an alternative to waiting, and records of the voice mails are queued, preferably in the same queue processing the live calls. In some embodiments the call center is enabled to process e-mails, video mails and facsimile messages as well as live calls and voice mail messages, and all types of multimedia communication can be queued in the same queue according to prestored routing rules and priority rules.
Abstract:
A system and apparatus within a communications server for intercepting supplemental service requests to a communications network and ensuring redirection to correct network party and optimal resource usage when redirecting a call over the network. The optimization system includes a database (131) and database server software (122). A device/trunk handler (121, 123) is used to interface signalling channels to the optimization system. A monitoring and statistics unit (127) monitors the signalling channels. The server software (122) is responsive to the monitoring and statistics unit (127) and selects the routing of the supplementary service through the appropriate server(s) in the network.
Abstract:
In one aspect of the present invention, an application provider, such as a mobile application part provider (52), is provided that includes a table (210), a router (200) and a message converter (220). The table (210) stores information corresponding to a sub-system, such as a visitor location register (46) or a home location register (44), of a first node, such as an integrated wireless telecommunications switch (14). The router (200) analyzes an application part message, such as a mobile application part message, that originated from the first node and compares the information stored in the table to the destination of the application part message to determine if the application part message is destined for the sub-system of the first node. The router (200) communicates the application part message to the first node if the application part message is destined for the sub-system of the first node. The message converter (220) converts the application part message to a transaction capability application part message if the router (200) determines that the application part message is not destined for the sub-system of the first node.
Abstract:
The Area Wide Centrex service is provided in a telephone communication network having a plurality of interconnected central office switching systems (11, 13, 15, 17), each at a different location. Each of the central office switching systems connects to a number of local telephone lines, a number of which can be designated as members of a business group for a particular customer. Area Wide Centrex extends a number of service features to the business group over a broad area through multiple central offices by taking the programming intelligence capacity out of the central offices and moving it to a central point (40). Service features such as call routing are controlled by data stored in a central data base (43). Establishing or changing services for one or all of a particular customer's lines requires only reprogramming that customer's data in the central data base (43), without the need to reprogram each central office switch. Also, Centrex services such as extension number type intercom dialing and call transfer, which previously could be provided only between lines connected to the same exchange, can be extended across exchanges.
Abstract:
Voice over Internet Protocol (VoIP) operations are utilized to substitute for the allocation of voice trunks in a conventional telecommunications network during intersystem handoff operations. A pair of VoIP gateways are in electronic communication with mobile switching centers. The VoIP gateways are connected by an Internet Protocol network. A determination is made that a handoff forward call connection operation should occur. A second VoIP gateway is allocated to the Target MSC, while a first VoIP gateway is allocated to the Serving MSC. A voice path is then completed using voice channels between the VoIP gateways and the MSCs, to allow the mobile station communication to be handed off from the Serving MSC to the Target MSC. Formatting and recovery of the voice audio signals occurs within the VoIP gateways as they are sent to and received from, respectively, the MSCs.
Abstract:
At least one part of at least two user connections (TA1...6) having configured performance criteria and being allocated to at least two network devices (LE1...3) is assigned to at least one group (NWHG), to which group-specific performance criteria and/or characteristics (PDN, HUNT) can be allocated. The group (NWHG) is controlled by one of the network devices (LE1), whereby the user connections (TA1, 3, 4, 6) which have not been physically allocated to this network device (LE1) are allocated to said device as virtual user connections.
Abstract:
A method and a mobile communication system for transmitting calls. The mobile communication system comprises at least one mobile services switching centre, a service control point for an intelligent network and at least one terminal communicating with the mobile services switching centre. Subscriber status information and location information on the terminal as well as information on an incoming call to the terminal are transmitted from the mobile services switching centre to the intelligent network service control point. At the control point, the subscriber status information on the terminal is checked and a command is transmitted to the mobile services switching centre either to connect the call to the terminal in response to the fact that the subscriber status information on the terminal indicates that the terminal is able to receive the call or to arrange the incoming call in a queue in response to the fact that the subscriber status information on the terminal indicates that the terminal has such a status which does not allow it to receive the call. Information on the calls in the queue is maintained in the control point wherefrom a command is transmitted to the mobile services switching centre to connect a first call in the queue to the terminal in response to the fact that the subscriber status information on the terminal indicates that the terminal is able to receive the call.
Abstract:
The invention relates to a method and a system for call transfer. A communication that has been established between a A-subscriber and a B-subscriber is established between the B-subscriber and a C-subscriber upon the request of the A-subscriber. The signaling information given by the A-subscriber is evaluated in a nodal point (ZK) that is specifically provided for this purpose and that prompts the call transfer. The invention provides a method and a device that allows a call transfer with only few special devices needed in the network interconnection and that makes this service available also to subscriber terminals that are not specifically equipped for it.
Abstract:
State information for a call between a calling party and a called party is established without maintaining the state information at a gate controller. A setup request for the call is received at an originating gate controller. The originating gate controller is connected to a trusted network. The calling party is associated with an originating interface unit coupled to an untrusted network. The setup request for the call is authorized. The authorized setup request is sent to the called party. State information for the call is formatted based on a setup acknowledgment message received from the calling party. The state information for the call is sent from the originating gate controller to the originating interface unit without maintaining the state information at the originating gate controller.
