Abstract (en)
[origin: WO0030391A1] The present invention is directed to telecommunications systems and methods for preventing the tracking of subscriber's movements through the interception of temporary identifiers utilized in network (10) access by and in interaction with mobile stations (20). In a preferred embodiment of the present invention, a mobile station (20) and the subscriber network (10) synchronize a pseudo random number generator, the initial seed value for which is exchanged. Subsequent temporary identifiers for the mobile station (20) are derived from successive values of a shared pseudo random number generator algorithm.
