摘要:
A method for transmission of data requires a transmitting node sending a request message identifying at least one time slot that is available for the transmitting node to transmit a data transmission to a plurality of receiving nodes, a first receiving node transmitting a first time slot grant message in response to the request message, a second receiving node transmitting a second time slot grant message in response to the request message, the transmitting node receiving the first and second time slot grant messages, the transmitting node evaluating the first and second time slot grant messages to determine at least one available time slot for transmitting, the transmitting node transmitting at least one confirmation message to the first and second receiving nodes, and the transmitting node transmitting the data transmission in the at least one available time slot identified in the at least one confirmation message.

The invention relates to a method for transmitting user data, particularly user data realizing real-time applications, between at least one first communication device and at least one second communication device, the user data being transmitted as data packets during a communication connection, wherein during the communication connection at least from the first communication device at least one packet enabling an authentication of the first communication device is embedded in at least one of the data packets transmitting the user data and directed at the second communication device. The invention furthermore relates to an arrangement for carrying out the method.

The invention relates to a communication network, especially a packet-switched communication network, provided with communication components having client and server functionalities. The client functionalities of the communication components have search functions for determining the current addresses of the communication components of the communication network which enable the server functionalities thereof to be used. A plurality of communication components have both client and server functionalities. Information relating to the intrinsic server functionalities can be directly retrieved by means of client functionalities of other communication components and can be directly used.
摘要:
In one aspect, a database in which target subscribers of different subscriber classes that can be reached via a communications system are allocated, and one respective marketer is assigned to each of the subscriber classes. When the communications system establishes a first communications relation between a first subscriber and a target subscriber while using a destination address given by the first subscriber, the subscriber class of the target subscriber is determined based on the destination address. The determination of the subscriber class results in the establishment of a second communications relation between the first subscriber and a marketer assigned to the determined subscriber class.

A method, a system and a terminal for occupying a key and a display field that is associated with the key of a first end device of a first subscriber. An address identifies the second end device of a second subscriber. Following user input of the first subscriber. The detected second address is assigned to the key as a target address for setting up a future connection. Associated subscriber information is determined for the detected address, and the determined subscriber information is assigned to the display field.

A method and apparatus dynamically pair a user's communication devices with a personal survivability gateway. The gateway can support the establishment of communication services in case of a network failure between a site where the user's communication devices are located and the site that provides the user's communication services. Preferably, the survivability gateway is configured so that if a network failure occurs, the user does not experience service degradation, or at least significant service degradation. For instance, the user's inbound and outbound communications during such an outage may be routed through his personal survivability gateway and a survivability proxy to limit, if not eliminate such service degradation.

The invention relates to methods and a communication device for establishing a communication transmission (ALTV), wherein upon detecting an original signaling (SIGRA) directed from a first terminal (EG2) to a second terminal (EG2) within the scope of an establishment of a connection, the second terminal (EG2) being addressed via a target address associated with the second terminal (EG2), it is recorded in what quantity further signalings (SIGRA) having the same sender address specifying the first terminal (EG1) and the same target address are detected within the scope of further attempts to establish a connection. An evaluation of time information is carried out with regard to the times of the detection of the detected original signaling (SIGRA) and the detected further signalings (SIGRA) in relation to at least one predetermined time period. In case of a positive evaluation result, and upon exceeding the recorded number of detected further signalings having the same sender address and the same target address compared to a comparison value, an alternative communication transmission (ALTV) is established for a connection establishing attempt detected last of the further connection establishing attempts.

The invention relates to a method and to a device for the bidirectional address conversion in SIP-controlled data streams between IPv4 data devices (T2) and IPv6 data terminals (T1) in mixed IPv4 and IPv6 data networks using an address converter (AU) and an address converter (AU) integrated in a SIP server (S1 or S2).
摘要:
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).
摘要:
One network protocol (RTP) each, having data packets (dp) comprising an expandable header (KE) is provided for a data stream (ds1 . . . n) encoded in a manner individual to said data stream, and the key information (si1 . . . n) formed in a data stream manner individual to said data stream is inserted into an expandable header (RTPH) of a data packet (dp) of the respective data stream (ds1 . . . n) and transmitted. The key information (sp1 . . . n) is selected in a manner individual to said data stream from the expanded headers (KE) of received data packets (dp) of the respective data stream (ds1 . . . n), and the associated encoded data stream (ds1 . . . n) is decoded by means of at least one piece of selected data stream individual key information (si1 . . . n). The forming and inserting of key information (si1 . . . n) into standard expanded headers (KE) can be performed with little additional expense, thus significantly reducing the expenditure for the analysis or diagnosis of the simultaneously transmitted encoded data streams (ds1 . . . n). Advantageously, the insertion of key information (si1 . . . n) can be activated or initiated only if the diagnosis or analysis and/or the recording of the data streams is currently being performed.
