ENHANCING PRIVACY IN CELLULAR PAGING SYSTEM USING PHYSICAL LAYER IDENTIFICATION

摘要

A method for negating location privacy attacks in cellular networks involves signal processing techniques at the physical identification layer. In particular the methodology involves embedding user's unique tags onto the downlink paging signal waveforms so that the tags are stealthy and robust. The scheme not only improves users' privacy but also saves system bandwidth.

1. A computer implemented method for a wireless communication system including a base station paging system for locating a mobile station within the base station dedicated broadcast region while preserving the location privacy of the located mobile station, the method comprising:
at least one processor with accessible input/output and at least one data store to perform the following:
generating a paging message;performing channel coding on the paging message;modulating the coded paging message;generating a unique tag for each one of a plurality of mobile stations;embedding at least one of said generated unique tags with the modulated coded paging message;transmitting the modulated coded paging message with the at least one embedded unique tag.
