Abstract: A private IP address is converted into a public IP address in a communications network without adapting a client software. The conversion of the private IP addresses into the public IP addresses is carried out via a network address translation. The private IP address of each terminal included in a payload of the IP data packet is convertible into a corresponding public IP address and, if necessary, vice-versa.

Abstract: 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.

Abstract: First information and second information is stored in the communication system for a callback after a first communication terminal attempts a call to a second communication terminal in which the connection is not established. The first information allows the second communication terminal to display the attempted call so that a callback to the first communication terminal can be executed on the part of the second communication terminal. The second information includes a charge type for the callback correlating at least to the attempted call.

Abstract: The invention relates to a method for managing communication connections in a communication system, comprising the following steps: generation of a connection request with a source network address internally valid in the communication system, over at least one network address translating network node to a network element outside the communication system, acceptance of a connection confirmation with a valid network address of a network element outside the communication system, providing the source network address internally valid in the communication system an the network address valid outside the communication system to a connection entry provided on the network element outside the communication system.

Abstract: A method of controlling provision of audio communication on a network comprising at least two endpoints (1, 3), at least one acting as a source and at least one acting as a destination, comprises setting a desired maximum and minimum packet size at the source; setting a desired maximum and minimum packet size at the destination; determining a minimum send packet size as the greater of the desired minimum set by the source and the desired minimum set by the destination; setting a jitter buffer at the destination to an appropriate size for the determined minimum send packet size; and transmitting audio packets of a size greater than or equal to the determined minimum send packet size.

Abstract: A location information (li) which is available in a mobile terminal device (ME-T) and which indicates the geographical location of the terminal device (ME-T) is embedded in messages (m) of a SIP protocol (SIP) which are exchanged between the terminal device (ME-T) and the network (WLAN) during the establishment of a session and/or during a session and/or during the registration of a terminal device (ME-T) in the network (WLAN), e.g. LAN or UMTS, or during request of a service or a function. By advantageously complementing the SIP protocol (session initiation protocol), the location information can be transmitted from a mobile terminal device (ME-T), which optionally has a telephone function, to the network (WLAN) in any signaling state, thereby substantially reducing the economic outlay for implementing the transmission of location information (li) to the network (WLAN).

Abstract: Transmission parameters for the transmission of at least one ticker information (ti) are transmitted during signaling of the transmission parameters for at least one multimedia data stream (mmd) for a session (S), the parameters establishing an additional logical transmission channel for the transmission of ticker information (ti), specifying the transmission protocol (RTP) and the payload type (555,666, 777,888) and inserting a source information which shows the source of the ticker information (ti). A session description protocol (SDP) embedded in a session initiation protocol (SIP) is used to describe and administer the transmission parameters. The invention allows the signaling for the additional information or ticker information (ti) to be implemented into existing network protocols for packet-oriented networks with only minor additional signaling and transmission operations.

Abstract: A video conference server in a digital data network that includes at least one audio port and at least one video port, a memory unit, an audio processing unit, a video processing unit, a control unit that generates control signals, a memory device, an access program module and a content program module. The audio and video port connect to a client workstation via the digital data network. The client workstation has a video output and an audio output. The memory unit associates an audio channel and a video channel of the digital data network with a client workstation. The audio processing unit and video processing unit receive signals from the audio and video port and generate signals for transmission to the client workstation.

Abstract: 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.

Abstract: There is described a system for switching from an established media path to a new media path for packets transmitted between first and second end points in a packet based network. An instruction is transmitted to the first end point instructing it to set up a new receiving channel for receiving packets transmitted from the second end point over the new media path. An instruction is transmitted to the second end point instructing it to configure a sending channel to send packets over the new media path for reception on the new receiving channel of the first end point. For a time period during the switching, the first end point monitors for packets simultaneously on both its new receiving channel and an established receiving channel configured to receive packets transmitted from the second end point over the established media path. This systems helps ensure a seamless switchover from the established to the new media paths.

Abstract: After the input of a subscriber (TLN1) of the first terminal (EG1), a connection to a temporarily available voice memory (SPS) is signalized by the same, and subsequently a voice message (spn) and at least one piece of retrieval information (ai) identifying the second terminal (EG2) is transmitted and stored at that location. Subsequently, the connection is terminated and the second terminal (EG2) is informed of the presence of a retrievable voice message (spn) in the voice memory (SPS) via the voice memory (SPS) by means of the at least one piece of retrieval information (ai), and the voice message (spn) can be retrieved from the second terminal (EG2) by means of the transmitted retrieval information (ai), or is transmitted to the second terminal (EG2) by the voice memory (SPS). In this manner voice messages (spn) can be stored for terminals (EG2) and retrieved by the same, regardless of whether one or no voice memories—such as an answering machine—is associated with these terminals (EG2).

Abstract: 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.

Abstract: Disclosed is a method for controlling a connection, according to which a signaling control device of the communication network triggers a first of several terminal points of the communication, which are connected via a user data channel, to close the user data channel by transmitting a first signaling message. The signaling control device also transmits a confirmation request message to a second of the terminal points of the communication, thereby triggering said second terminal point to transmit a confirmation message to the signaling control device if the user data channel has been successfully closed. If the signaling control device receives the confirmation message, the signaling control device triggers a terminal point of the communication to open at least one new user data channel by transmitting a second signaling message.

Abstract: 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.

Abstract: Conference participants are selected via a network element in a network, the geographical area locations, for example, buildings of an enterprise, of the conference participants are determined and depending on the determined locations a geographical conference area, for example a conference room is determined for each conference participant. The conference area together with the conference information is communicated to the conference participants. The availability of the conference participants can be checked for the communication.

Abstract: To control a conference circuit between multiple terminal devices in a packet-oriented communication network, circuit-oriented conference control signaling is transmitted via a packet-oriented transport protocol between a first terminal device and a communication server of the communication network. Setting up of packet-oriented media channels between the terminal devices and a packet-oriented conference mixing device is initiated by the communication server depending on the conference control signaling.
