Intercom network, mobile terminal, and method
An intercom network for real-time audio communication between users has a stationary element to which the users are connected, a mobile terminal that comprises an audio input and that can transmit audio signals wirelessly to the stationary element or to another user, and a device in the stationary element for user management, that administers the users connected to the stationary element, and that carries out an authorization check for logging the mobile terminal onto the stationary element. An NFC element is provided in the device on the stationary element, and an NFC counter-element is provided on the mobile terminal that can transmit authorization information to the NFC element when the mobile terminal approaches the stationary element.
1. An intercom network for real-time audio communication between users, the network comprising:
a stationary element to which the users are connected;
a mobile terminal that has an audio input and that can transmit audio signals wirelessly to the stationary element or to another user;
a device in the stationary element for user management, that administrates the users connected to the stationary element, and that carries out an authorization check for logging the mobile terminal onto the stationary element;
an NFC element in the device on the stationary element; and
an NFC counter-element on the mobile terminal that can transmit authorization information to the NFC element when the mobile terminal approaches the stationary element.
2. The intercom network according to claim 1 , wherein the authorization information comprises a unique identification of the mobile terminal.
3. The intercom network according to claim 2 , wherein the device, in the course of carrying out the authorization check, permits logging the mobile terminal onto the stationary element only if the unique identification is stored as authorized identification in a memory of the device.
4. The intercom network according to claim 1 , wherein a plurality of mobile terminals are provided.
5. The intercom network according to claim 4 , wherein the mobile terminals each comprise a respective NFC counter-element with its own identification.
6. The intercom network according to claim 1 , wherein a plurality of stationary elements is provided and the devices each comprise a NFC element for each of the stationary elements.
7. The intercom network according to claim 4 , wherein, by a relative approach of a first mobile terminal toward a second mobile terminal, authorization information can be transmitted by the NFC counter-element of a second mobile terminal to the NFC counter-element of the first mobile terminal and from there onward to the NFC element of the stationary element.
8. The intercom network according to claim 1 , further comprising:
an actuating element on the mobile terminal that when actuated logs the mobile terminal out of the intercom network.
9. A mobile terminal for use in an intercom network according to claim 1 , wherein the NFC counter-element on the mobile terminal can transmit authorization information to the NFC element on the stationary element when the mobile terminal approaches the stationary element of the intercom network.
10. The network according to claim 1 , wherein the mobile terminal has, separate from the respective NFC counter-element, a communication module for receiving and transmitting audio signals.
11. A method of logging a mobile terminal onto a stationary element of an intercom network having users that can transmit audio signals wirelessly to conduct real-time audio communication, the method comprising the following steps:
providing a stationary element provided with an NFC element,
providing a device for user management and with which the users connected to the stationary element can be administered,
providing a mobile terminal on which an NFC counter-element is provided,
configuring the intercom network by storing a unique identification of the mobile terminal in a memory of the device, and
logging the mobile terminal onto the stationary element by bringing the mobile terminal close to the stationary element such that, as a result of the approach, authorization information is transmitted by the NFC counter-element of the mobile terminal to the NFC element on the stationary element.
12. The method defined in claim 11 , further comprising the step of:
receiving or transmitting the audio signals between the mobile terminal and the stationary element or any other user via a communication module in the mobile terminal, the communication module being separate from the respective NFC counter-element.
13. An intercom network for real-time audio communication between users, the network comprising:
a stationary element to which the users are connected;
a mobile terminal that comprises an audio input and that can transmit audio signals wirelessly with the mobile terminal to the stationary element or to another user;
a device in the stationary element for user management that administers the users connected to the stationary element and that carries out an authorization check by the device for logging the mobile terminal onto the stationary element;
an RFID element in the device on the stationary element; and
an RFID counter-element on the mobile terminal for transmitting authorization information by the RFID counter-element to the RFID element when the mobile terminal approaches the stationary element.
