Abstract:
During the output of data and distribution services, user data streams frequently transferred to a corresponding communication device (i.e. information output system and/or the distribution system) are possibly irrelevant to the server. Despite this, resources for the processing of incoming useful data flows inside the communication device are provided in many cases on account of compatibility grounds. As a result, energy is reduced in the communication device. According to the invention, in order to reduce the efforts involved in processing useful data transferred in the direction of the communication device, at least one part of useful data is discarded prior to the implementation of working steps provided for the processing of useful data.
Abstract:
The invention relates to a distribution of load to peripheral adaptation units of a packet-based switching system, whereby the peripheral adaptation units serve as an interface between the packet-based switching center and a packet-based communications network. According to the invention, a load that accrues in the switching center is statically or dynamically distributed to the peripheral adaptation units by a load distributor. This enables the periphery adaptation units to be utilized whereby preventing wiring-related overloads and, in addition, being able to take different performance capacities of the peripheral adaptation units into account. When at least one additional switching center is provided upstream, a load budget concerning its use of the peripheral adaptation units can be transmitted thereto from the packet-based switching center. The load distribution is adapted in the event of hardware failures and signaling interferences.
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.
