Abstract

The invention proposes a method for power-saving operation of communication terminals in a communication system, particularly in a wireless communication system, where a central station in the communication system takes a user input as a basis for prompting a change in an operating state of the communication terminals in the communication system which is characterized by the power consumption. Preferably, the method is used in wireless conference systems, with the communication terminal being in the form of a participant unit and/or chairman unit.

Claims

1. A method for a power-saving operation of communication terminals (12, 14) in a communication system, in particular in a wireless communications system,

wherein a switching center (10) of the communications system, as a function of a user input, prompts a change of an operating state of the communication terminals (12, 14) of the communication system, which operating state is characterized by the power consumption.

2. The method as recited in claim 1,

wherein the switching center (10) switches the communication terminals (12, 14) into a power-saving standby mode.

3. The method as recited in claim 1,

wherein the switching center (10) switches the communication terminals (12, 14) from a power-saving standby mode (30) into a normal operating mode (32).

4. The method as recited in claim 1,

wherein the user input occurs in the switching center (10) or on a computer (16) connected to the switching center (10).

5. The method as recited in claim 1,

wherein the user input takes place in a communication terminal (12, 14), whereupon the communication terminal (12, 14) sends the switching center (10) a message that prompts the switching center (10) to change an operating state of the other communication terminals (12, 14), which operating state is characterized by the power consumption.

6. The method as recited in claim 5,

wherein the message that the communication terminal (12, 14) transmits to the switching center (10) prompts the switching center (10) to switch the other communication terminals (12, 14) into a power-saving standby mode (30).

7. The method as recited in claim 6,

wherein the switching center (10), based on the received message, transmits another message to the other communication terminals (12, 14), which then switch into the power-saving standby mode (30).

8. The method as recited in claim 5,

wherein the message that the communication terminal (12, 14) transmits to the switching center (10) prompts the switching center (10) to switch the other communication terminals (12, 14) from a power-saving standby mode (30) into a normal operating mode (32).

9. The method as recited in claim 8,

wherein the switching center (10), based on the received message, transmits another message to the other communication terminals (12, 14), which then switch from the power-saving standby mode (30) into the normal operating mode (32).

10. The method as recited in claim 2,

wherein input units and/or output units of the communication terminals (12, 14) are nonfunctional in the power-saving standby mode (30).

11. A switching center (10), in particular equipped with means for carrying out the method as recited in claim 1,

wherein the switching center (10) is configured so that the switching center (10), as a function of a user input, prompts a change of an operating state of the communication terminals (12, 14) of the communication system, which operating state is characterized by the power consumption.

12. A communication terminal (12, 14), in particular equipped with means for carrying out the method as recited in claim 1,

wherein the communication terminal (12, 14) is configured so that as a function of user inputs into the communication terminal (12, 14), the communication terminal (12, 14) sends the switching center (10) messages that are suitable for prompting the switching center (10) to change an operating state of other communication terminals (12, 14), which operating state is characterized by the power consumption.

13. A use of a switching center (10) as recited in claim 11 and a communication terminal (12, 14) in a conference system, in particular in a wireless conference system,

wherein the communication terminal (12, 14) is embodied in the form of a participant unit and/or a chairperson unit.
