Abstract

There is provided a terminal device comprising a processing unit for controlling the functions of the terminal device, a communication unit for communicating with one or more communication devices, and a user interface. The communication unit is configured to query for nearby communication devices utilising wireless local connectivity technologies, and to detect the proximity range parameters of each queried communication device at predetermined times; the processing unit is configured to update a proximity overlap duration value of each queried communication device on the basis of the detected proximity range parameters of the queried communication devices at the predetermined times; and the user interface is configured to indicate information related to the updated proximity overlap duration values of one or more queried communication devices.
