Abstract
Disclosed is a method in which a detection request, by means of which an identifier of a calling terminal is to be detected, is addressed to a signaling unit by a called terminal. The called terminal is connected to a data packet transmission network. The signaling unit signals according to a signaling protocol that has been defined for the transmission of data in a data packet transmission network. The detection request is transmitted along with a message and/or an information element which has been established for signaling in the data packet transmission network.
Claims18
A method for detecting a malicious call, comprising:
- receiving, by a signaling unit, a first call request of a calling terminal;
- sending a second call request from the signaling unit to a called terminal device, the called terminal device operates according to a session initiation protocol;
- enabling a data transmission between the calling and called terminal device;
- transmitting user data between the calling terminal device and the called terminal device;
- receiving a detection request in order to detect the malicious call of the calling terminal, the detection request initiated by a user of the called terminal and formed according to the session initiation protocol;
- noting, by the signaling unit, an identifier for the calling terminal device;
- and
- storing the identifier permanently in a memory unit after receiving the detection request;
- wherein the called terminal device is a terminal device in a data packet transmission network,
- wherein the signaling unit performs signaling between the signaling unit and the called terminal device in accordance with the session initiation protocols,
- wherein the detection request is transmitted in an INFO message using the INFO method according to RFC 2976, and that a header section of the INFO message or a body section of the INFO message contains an information element which serves to uniquely identify the detection request.
A session initiation protocol terminal device for detecting electronic calls, comprising:
- a connection unit for connecting the session initiation protocol terminal device to a data packet transmission network;
- and
- a control unit containing a function that generates a detection request automatically at the instigation of a person operating the session initiation protocol terminal device, the detection request generated according to a session initiation protocol and subsequently sent to a signaling unit, and when the detection request is processed the signaling unit notes an identifier of a terminal device calling the terminal device,
- wherein the detection request is in order to detect a malicious call from the terminal device calling the terminal device, and
- wherein the detection request is generated in an INFO message using the INFO method according to RFC 2976, and that a header section of the INFO message or a body section of the INFO message contains an information element which serves to uniquely identify the detection request.
A signaling unit for detecting electronic calls, comprising:
- a control unit that signals and provides a function that automatically notes an identifier of a terminal device calling the called terminal device;
- a session initiation protocol used to provide signaling between the signaling unit and the called terminal device, and
- a detection request message from the called terminal device, the message indicating that the call from the calling terminal device is a malicious call, the detection request formed according to a session initiation protocol,
- wherein the detection request is generated in an INFO message using the INFO method according to RFC 2976, and that a header section of the INFO message or a body section of the INFO message contains an information element which serves to uniquely identify the detection request.
