A method for supporting the discovery of synchronized clusters (4) of mobile stations (3) in a wireless communication network (1), wherein a synchronized cluster (4) includes a number of mobile stations (3) that periodically wake up according to a common duty cycle, is characterized in that at least one mobile station (3) of a synchronized cluster (4)—announcement master (6)—transmits advertising messages announcing the existence of said cluster (4) to potential scanning devices (5) that try to discover said cluster (4), wherein an independent infrastructure including a plurality of access points (2) which transmit beacon frames on a regular basis is employed as external synchronization source in that said announcement master (6) as well as potential scanning devices (5) apply predefined rules to derive from information contained in the beacon frames transmitted by access points (2) of said independent infrastructure time slots of said advertising messages, which are used as common rendezvous points. Furthermore, a corresponding system is disclosed. |
