Abstract

A Cell-ID translation module accesses a Cell-ID translation database to associate original Cell-ID information with new or changed (i.e., translated) Cell-ID information received by a handset. A Cell-ID database is effectively regularly changed rendering useless any third party databases previously collected without authorization by the relevant mobile operators. Cell-IDs collected by unauthorized third parties will either not be found in the third party database, or not match up to the correct location.

Claims

1. A method of securing cell site identifier code information in a wireless network, comprising:

accessing a secure cell site identifier code translation database containing regularly changed translations between actual, unique static cell site identifier code information, and corresponding translated, unique static cell site identifier code information; and

regularly translating an actual, unique static cell site identifier code associated with a given wireless device in a wireless network into its corresponding current translated, unique static cell site identifier code, while leaving said actual, unique static cell site identifier code associated with said given wireless device unchanged;

wherein a regularly changed, translated cell site identifier code, in place of said unique static Cell-ID associated with said given wireless device, is passed to another wireless device.

2. The method of securing cell site identifier code information in a wireless network according to claim 1, wherein:

said corresponding translated, unique static cell site identifier code is changed periodically.

3. The method of securing cell site identifier code information in a wireless network according to claim 1, wherein:

said corresponding translated, unique static cell site identifier code is changed intermittently.

4. A network translation apparatus, comprising:

a secure cell site identifier code translation database containing a plurality of regularly changed translations between actual, unique static cell site identifier codes of given nodes in a wireless network, and corresponding translated, unique static cell site identifier codes;

a translator, in communication with said cell site identifier code translation database, to regularly replace, in a communication with but not in said given nodes in said wireless network itself, an actual, unique static cell site identifier code with its corresponding regularly changed, translated, unique static cell site identifier code, while leaving said actual, unique static cell site identifier codes unchanged; and

a transmitter to transmit a regularly changed, translated cell site identifier code, in place of said actual, unique static cell site identifier code associated with a given node in said wireless network, to a device outside said wireless network.

5. The network cell site identifier code translation apparatus according to claim 4, wherein:

said translator of said actual, unique static cell site identifier code periodically changes said translated, unique static cell site identifier code.

6. The network cell site identifier code translation apparatus according to claim 4, wherein:

said translator of said actual, unique static cell site identifier code intermittently changes said translated, unique static cell site identifier code.
