Abstract
A method is provided wherein idle periods occurring in the data transmission between various services are detected by means of a Power Manager, whereby the infrared link (IrDA-SIR) is shut down automatically. The link restarts automatically when new activity is detected. Thanks to the method, at least one of the stations can also go into the sleep mode, even though a virtual link to the application layer (7) of the other station is maintained in the application layer (7).
