Abstract
The invention relates to a technique for determining the presence of a peripheral device (23, 26) in a service area of a local network (2). The local network includes a gateway (20) for accessing a communications network (1) and at least one relay device (21, 24). The peripheral device and the relay device(s) are arranged to communicate with other devices via a radio-access network. The access gateway controls at least one relay device, so that the latter scans frequencies for accessing the radio-access network. When the relay device receives an announcement message from the peripheral device, said relay device transmits a notification of detection of the peripheral device to the access gateway. The peripheral device is then identified as being present in the service area.
