DETERMINING A POSITION OF THE TERMINAL DEVICE IN A WIRELESS COMMUNICATION SYSTEM
The present invention relates to a method for determining a position of a terminal device (110) in a wireless communication system (100). According to the method, a first message (130-133) is broadcasted by the terminal device (110). The first message (130-133) comprises a positioning request and a terminal identifier identifying the terminal device (110). The first message (130-133) is received at a group of neighboring devices (120-123). Each neighboring device of the group of neighboring devices (120-123) is located within a wireless radio communication range of the terminal device (110). From one or more neighboring devices (120, 121) of the group of neighboring devices (120-123) a corresponding second message (140, 141) is transmitted to location server (103) of the wireless communication system (100). The second message (140, 141) comprises the terminal identifier and an indication that the terminal device (110) requested a positioning. For each neighboring device (120, 121) of the one or more neighboring devices a corresponding position information is determined. The position of the terminal device (110) is determined at the location server (103) based on the position of the one or more neighboring devices (120, 121).

NETWORK ARCHITECTURE, RADIO FREQUENCY BASED ASSET TRACKING AND/OR LOCATION ESTIMATION METHODS AND SYSTEMS
Radio frequency-enabled nodes, in an example asset tracking system, receive a basic message including an asset tracking tag identifier from an asset tag. The nodes measure a signal attribute of the received message; and each receiving node transmits a node asset message including the asset tag identifier, a respective node identifier, and the measured signal attribute. Edge gateways each receive one or more node asset messages transmitted by some number of the radio frequency-enabled nodes and rank respective node identifiers based on the measured signal attribute. Each edge gateway forwards an aggregated message to a fog gateway, which parses data from the aggregated messages to form a node identifier tuple identifying at least three nodes near the asset tag. Ordered identifiers from the tuple and known locations of the identified nearby nodes can then be processed to estimate of the location of the asset tag.
