Abstract
The invention relates to the field of mobile computing and more specific to the problem of determining the current position of a mobile device (1). If the mobile device (1) can attach itself to (wireless) networks (4) covering a small geographic area, the mobile device (1) can determine its position by querying stationary nodes attached to the network about their location. According to the invention a transmission of position information from a stationary node (3) to a mobile device (1) is effected above the transport layer (layer 4) of the OSI model such that the transmission is independent from the physical type of the networks (4) and/or the transmission (2) used.
