Abstract:
The invention relates to a method for the comfortable and consistent administration of subscriber-specific data and call processing features of a plurality of Multimedia Terminal Adapters of individual cable network telephony subscribers that are connected via one cable modem each to a broadband cable network used as the telephony access network in conjunction with at least one packet-based exchange for providing network and subscriber features, for processing signaling information and controlling the useful data transfer between the subscribers using suitable packet-based protocols. The method is furthermore characterized by a function that, for example, automatically provides a new cable network telephony subscriber with an allocation to a line unit of the exchange. This function also makes it possible for other telephony-relevant data and address positions to be input in a coordinated manner into the broadband cable network and the exchange. The allocation of the port address for the Multimedia Terminal Adapter of a cable network telephony subscriber to a line unit of the exchange can be carried out by the exchange itself, by a superordinate Network Management System and/or in the framework of a preconfiguration by means of at least one planning and configuration tool of the network provider upstream of the Network Management System. The advantages of the inventive system consist mainly in releasing the network provider from any call processing-specific additional addressing of cable network subscribers and in allowing for a decomposition of symbolic addresses during start or restart of the exchange, expired period of validity of the addresses or in the failure mode.
Abstract:
The invention relates to an interactive voice response (IVR) system supplying functions and resources to services encompassing interactive voice response or output of announcements and three methods for dealing with resource bottlenecks of the IVR system. The IVR system supplies a pool of resources to several switching systems. Virtual, individually assigned IVR systems are created from the perspective of the switching systems by allocating the control interfaces and user data interfaces of the IVR system in an exclusive, disjunctive manner to the switching systems. Resource bottlenecks can be prevented when several switching systems access the IVR system by rejecting jobs for which the required resources cannot be reserved or by aborting jobs creating too substantial delays during processing due to the wait for resources. The invention has the advantage of efficiently utilizing the resources supplied by the IVR system.
Abstract:
A 1:1 redundancy is provided. An identical clone being assigned to each switching system that is to be protected as a redundant partner comprising identical hardware, software, and database. The transfer is done in a fast, secure, and automatic manner by a superimposed, real-time capable monitor which establishes communication to the switching systems that are arranged in pairs. The transfer to the redundant switching system is done with the aid of the network management and the central controllers of the two switching systems.
Abstract:
An individual accessibility profile specific to each subscriber is created when the communication connection is established, and a connection to the at least one communication terminal is established as required, according to the data stored in the accessibility profile, the information being supplied to the subscriber via connection when the subscriber is reached, and acknowledged by the subscriber on receipt thereof. Thus a subscriber is provided with information in the event of there being an imminent high level of danger or ecological catastrophe.
Abstract:
In one aspect, a method for error detection in a packet-based message distribution system, according to which messages are distributed via a plurality of nodes and other system components, and each node comprises at least two addressable interfaces is provided. For the security of the system, the message distribution paths are designed in a redundant manner and redundancy paths are available in the message distribution system in the event of the breakdown of connections in the message distribution system. The invention topology of the message distribution system is known by the nodes, and the nodes check the accessibility of the other nodes by means of communication tests; interrogate intermediate system components by means of existing interfaces and in terms of the connection status thereof in relation to other nodes and/or system components, and signal optional error configurations, physical errors, and/or missing redundancy paths of the message distribution system.
Abstract:
In one aspect of the invention, audio and video user data are separated. The audio user data is conducted via a TDM loop, where it is tapped and the video user data is fed to the recipient via the packet network, the separated audio and video user data are then combined again.
Abstract:
The invention permits service providers to self-configure message or dialogue services on an arrangement provided by an independent network operator. Said arrangement comprises a provider device, to which the service provider has access. Components or elements of messages or dialogues, altered or newly generated by service providers, stored in the provider device, are transmitted to one or more provision devices, where the above are available for information output devices for the processing of a new or changed message or dialogue service. According to the invention, an interface between service provider and network operator is achieved, which permits the service provider an efficient configuration of the services provided thereby and the use of resources provided by a network operator. As a result of the structure of the interface and by means of security measures undesired viewing or access to the resources of the network operator can be avoided.
Abstract:
The invention relates to the testing of transmission quality of transmission links in a packet network. According to the invention, the director and responder functionality are made available in a resource server of the packet network. In order to perform a quality test, a connection is set up between the resource server and at least one gateway and potentially between two gateways by a packet-oriented switching center. Test signals are transmitted by the resource server and, after being mirrored at one or two gateways, are transmitted back to the resource server. The broadcast test signals are evaluated for transmission-related reductions in quality, e.g. distortion and attenuation, and the results of this evaluation for different broadcast links are combined in order to obtain information concerning the transmission quality of individual partial links. The invention is advantageous in that it makes complicated and expensive test functions available on centralized resource servers. Since resource servers of this type are, for the most part, already provided for carrying out other functions in the packet network, e.g. IVR server, it is possible, as a rule, to make the test functionality available on existing servers.
Abstract:
The invention relates to the representation of ISDN connections, which is independent of the type of connection, in a packet-oriented exchange. By adapting the signaling information, which is transmitted by ISDN connections, in a peripheral adapter, different ISDN connection types can be handled as a standard connection type in the packet-oriented exchange. The adaptation can ensue, for example, with the aid of a conversion table for the useful data references and call identifiers comprising signaling messages. The invention is advantageous in that it involves an uncomplicated representation of ISDN data in the packet-oriented exchange. ISDN connection-related data do not need to be managed in the packet-oriented exchange.
Abstract:
Services and performance characteristics are more and more frequently defined according to standard descriptions and formats, which is the case also for announcement services and dialogue services required especially in network services, for example. The associated descriptions are also provided in a standard form, e.g. by means of VoiceXML. When a service is introduced in the network, said descriptions are inserted into the network nodes, application, and/or media server. A browser functionality which reads and interprets the VoiceXML pages is required for processing the VoiceXML description on a media server platform such that the necessary basic functions of the media server can be allocated to the desired service and can be controlled. Prior art uses media servers comprising a single VoiceXML browser. The problem with such commercial products lies in the resulting suboptimality in terms of resource utilization and expenses, which is the case particularly for simple applications. The invention resolves said problem by providing a plurality of browser functionalities. In the inventive multistep method, the optimal browser functionalities are determined step by step by evaluating signaling data and descriptive data as required.
