In a method for setting up a communication link between a first telephony terminal (PA) and a second telephony terminal (PB) in a communication network which transports data packets, in particular on the Internet, with the aid of at least one signaling Server (SA, SB), in particular with the aid of an SIP Server, the first telephony terminal informs a first signaling Server that a call is intended to be made to the second telephony terminal. The first signaling Server which has been informed or a second signaling Server which has been informed by this first signaling Server recognizes that the call is intended to be made with a particular quality of Service and sets up a communication link between the first telephony terminal and the second telephony terminal, which link corresponds to this quality of Service.

Method for setting up a communication link

The invention relates to a method for monitoring a communication system, comprising: acquiring and storing data about timeout events or faulty transfers in connection with at least one signaling process in at least one first communication terminal () of the communication system; and creating a collection of such data and transferring () said collection to a collection point () for said data in the communication system.

In a method for capturing and transmitting motion data (s) from a transmitter () to a receiver (), motion data is captured by a capturing device () at the transmitter end, said capturing device () registering the motion of an object () by means of at least one sensor () and converting the registered motion into a digital signal (i). Said digital signal is fed to the receiver, which embeds the data of the digital signal (i) in a series (i) 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.

Method for capturing and transmitting motion data

After the input of a subscriber (TLN) of the first terminal (EG), 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 (EG) is transmitted and stored at that location. Subsequently, the connection is terminated and the second terminal (EG) 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 (EG) by means of the transmitted retrieval information (ai), or is transmitted to the second terminal (EG) by the voice memory (SPS). In this manner voice messages (spn) can be stored for terminals (EG) and retrieved by the same, regardless of whether one or no voice memories&#x2014;such as an answering machine&#x2014;is associated with these terminals (EG).

Method, terminal and voice memory for storing voice messages in a communication network

With a method for communication in a communication network, a subscriber is assigned an authorization level depending on the respective applicable scenario at the time when the authorization level is assigned for that subscriber in that communication network.

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).

Method and terminal device for transmitting location information in internet-oriented networks

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.

Method and device for authenticating transmitted user data

Using a method for a subscriber unit's communication with a service that requires information about the subscriber unit's location, the subscriber unit sends the service a message containing information about the subscriber unit's location and at least one piece of information about the subscriber unit's location is stored in at least one network component and is made available by a network component.

Method for a subscriber unit's communication with a service and a component in a network

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.
