摘要:
Transmission resources are controlled in individual transmission paths in a packet-oriented communication network, whereby data-packet address information which identifies the origin and the goal of the data packets, is transmitted to a resource manager, responsible for a transmission path, from a network transmission device. On a resource request, for a connection to be subsequently generated, the origin and goal thereof are compared with the origin and goal of the previously transmitted data packets by the resource manager. Should there be agreement, the resource manager can deduce that the connection to be established can equally run over the corresponding transmission path. Correspondingly, establishment of further connections occurs, depending upon the available resources of the transmission path.

Transmission resources of one or more individual transmission links, especially of individual transmission bottlenecks, are managed by a resource manager. In the course of a setting up of a connection, the resource manager determines, by using an item of connection information, the origin and destination of the connection to be set up, and identifies whether this connection is routed over a particular transmission link. Based on the result of the determination, a message is subsequently generated and transmitted to the origin of the connection. A selection of transmission resources to be used for the connection is then carried out based on the transmitted message.

A method establishes a connection between a source network with a source network resource manager and a target network with a target network resource manager. According to the method, a connection control unit of the source network transmits a connection establishment signal to a connection control unit of the target network and—parallel to this—a reservation request to the target network resource manager. The target network resource reserves the requested resources and forwards the reservation request towards the target network resource manager, which also reserves the requested resources and transmits reservation information regarding the success of the resource reservations to the connection control unit of the target network.

Quality of service is assured for connections routed via a plurality of subregions of a packet-oriented network via connection paths having prescribed transmission system resources by a resource manager in the packet-oriented network which has access to associated information relating to address ranges of the subregions, routes from source subregions to destination subregions through other subregions, and prescribed transmission system resources between the subregions. When a connection is initialized, a requested scope of resources and source and destination addresses are signaled to the resource manager, and a route through the network is ascertained. Then, taking into account the requested scope of resources and the scope of resources between the subregions of the route, a check is carried out to determine whether the initialized connection is authorized. In addition, the transmission system resources may be reserved for the initialized connection in the subregions included in the ascertained route. The resource manager can be arranged centrally in the network in one of the subregions, and the connection controllers, e.g., the gatekeeper in H.323 networks, provided in the subregions involve the resource manager in the signaling that occurs when a connection is initialized.

According to the invention, a power characteristic information concerning a power characteristic profile of a target terminal is transmitted to a base terminal, before transferring signaling of a connection set up from a base terminal to a target terminal. As a result of the connection set up signaling, a power characteristic request is transferred based on the power characteristic information.
摘要:
A method for packet-oriented transmission of speech, audio, video and/or useful data between an internal and a public data network by means of a pre-reservation of NAT addresses. A pre-NAT address is allocated to the IP address of an internal computer by an NAT address server. The relevant allocation data set is available in a NAT host 200 which acts as a gateway between the internal and the public data network; whereby single addresses (pre-NAT addresses) are provided for transparent use of the data packet in the internal and public network when the information on the origin or destination in an IP Header or in the protocol data, in addition to the information on origin or destination in said header, is modi.

Method for the transmission of data between at least two communication devices, connected to each other by means of a data network, whereby information data for a security device, connected to the second communication device, for protection against an unauthorized access to the communication device, is transmitted by means of the security device and audio and video data is transmitted directly by by-passing the security device.
摘要:
Method of transmission of data between at least two communication devices which are connected together over a data network. The communication devices are respectively connected to a coding device and the sent data are source-and channel-coded by a coding method respectively furnished within the coding devices. The data are converted within a converting device connected to the data network.

In one aspect a method for implementation of a firewall application is provided, whereby, in one step of the initiation of a connection from the first to the second terminal, authentication of the first terminal is transmitted and, after successful authentication a selected address is communicated to the firewall device. In another aspect, an arrangement for carrying out the method is provided.
摘要:
In a method for capturing and transmitting motion data (s1) from a transmitter (103, 203) to a receiver (104, 204), motion data is captured by a capturing device (102, 202) at the transmitter end, said capturing device (102, 202) registering the motion of an object (106, 206) by means of at least one sensor (101, 201) and converting the registered motion into a digital signal (i2). Said digital signal is fed to the receiver, which embeds the data of the digital signal (i2) in a series (i3) of data and transmits said series of data to a receiver. In addition to or instead of the data of the digital signal, the series of data transmitted by the transmitter contains context data which the receiver uses to interpret and process the originally captured motion data within a defined context.
