method for determining a temporal reference and / or at least one spatial reference in a communication system

摘要

To determine a temporal reference and / or at least one spatial reference, in a communication system comprising a plurality of collection gateways (120-124) configured to transmit beacons, a device (110-111) performs for each beacon: 502) from it a current geolocation information of the collection gateway which transmitted said tag; obtain (503) information representative thereof of a communication technology used to determine said current geolocation; and obtaining (504) information from it indicating whether said current geolocation has been determined by internal means or by external means. the device then uses (509) the information thus obtained to determine the time reference to time and frequency synchronize said device and / or the spatial reference (s) to determine the geolocation of said device.
