Abstract

An anonymous location wireless network service for use in a wireless network that tracks the location and identity of network users, such as networks complying with enhanced 911 standards. The service provides content providers with the location of network users without revealing their identities. The service includes a wireless network having a proxy server, a network communication link to a plurality of web sites, and a wireless communication link to a plurality of handheld devices. The proxy server blocks identity by reading the location and identity information of network devices, generating dummy identifications, relating the dummy identifications to the identity information, storing the relationships in a memory storage, and forwarding the location information and dummy identifications to the global computer network. Upon receiving messages from the global computer network, the proxy server reads the dummy identifications, looks up the related identification information in the memory storage, and forwards the data to the appropriate network devices.

Claims

1. A method for providing an anonymous location service for use in a wireless network that tracks locations and identities of network users, the method comprising the steps of:

a) receiving the identity of a wireless network device;

b) receiving the location of the wireless network device;

c) substituting a dummy identification for the identity of the wireless network device; and

d) forwarding the location and dummy identification of the wireless network device to a web site through a global computer network.

2. The method, of claim 1, further comprising the steps of:

e) associating the dummy identification with the identity of the wireless network device into a relationship; and

f) storing the relationship in memory.

3. The method of claim 2, further comprising the steps of:

g) receiving a message from the web site, wherein the message includes the dummy identification;

h) locating the dummy identification in the memory;

i) using the relationship to determine the identity of the network device; and

j) forwarding the message to the network device.

4. The method of claim 1, wherein the steps of receiving the identity and receiving the location are initiated when the network device accesses a computer network through the wireless network.

5. The method of claim 1, wherein the steps of receiving the identity and receiving the location are initiated when the network device places a wireless telephone call.

6. The method of claim 1, wherein the step of forwarding comprises:

(i) receiving a message from the web site requesting communication with wireless devices in a particular location;

(ii) reading the location of the wireless network device;

(iii) forwarding the location and the dummy identification of the wireless network device to the a web site if the location matches the particular location.

7. The method of claim 1, wherein the dummy identification is the location of the wireless network device.

8. A method for providing an anonymous location service for use in a wireless network that tracks locations and identities of network users, the method comprising the steps of:

a) receiving the location and the identity of a network device;

b) providing the location and the identity to a first web site, the first web site receiving content;

c) receiving a request for content from the first web site including the identity;

d) generating a dummy identification and substituting the dummy identification for the identity;

e) recording an association between the dummy identification and the identity;

f) forwarding to a second website a modified request for content including the location and the dummy identification, the second web site providing content;

g) receiving from the second web site a content that references the dummy identification;

h) determining the identity of the network device using the dummy identification and the recorded association;

j) replacing the dummy identification referenced in the content with the, identity of the network device; and

i) forwarding the content including the location and the identity of the network device.

9. The method of claim 8, wherein the step of forwarding the content forwards the content to the first web site.

10. The method of claim 9, further comprising the steps of:

j) receiving a web page from the first web site including the content; and

k) forwarding the web page to the network device.

11. The method of claim 8, wherein the step of forwarding the content forwards the content to the network device.

12. The method of claim 8, wherein a proxy server of the wireless network executes steps (a) through (i).

13. The method of claim 8, wherein the dummy identification is the location of the network device.

14. A system for providing an anonymous location service for use in a wireless network that tracks locations and identities of network users, the system comprising:

a) a proxy server having memory storage;

b) a plurality of web sites in communication with the proxy server over a global computer network;

c) a plurality of handheld devices in communication with the proxy server over the wireless network; and

d) a location system in communication with the proxy server, wherein the proxy server receives the locations of the network users from the location system, receives the identities of the network users from the plurality of handheld devices, translates the identities of the network users into dummy identification and forwards the locations of the network users and the dummy identifications to the plurality of web sites.

15. The system of claim 14, wherein the memory storage is a database separate from the proxy server.

21. The system of claim 14, wherein the proxy server stores relationships between the identities and the dummy identifications in the memory storage.

22. The system of claim 21, wherein the proxy server receives messages from the plurality of web sites, wherein the messages reference the dummy identifications, wherein the proxy server consults the relationships in the memory storage and uses the dummy identifications to locate corresponding identities of network users, and wherein the proxy server forwards the messages to the corresponding identities.

23. The system of claim 14, wherein the proxy server reads the locations of the network users and forwards the locations of the network users and the dummy identifications to the plurality of web sites only if the locations correspond to a specific, location requested by the plurality of web sites.

24. The system of claim 14, wherein the dummy identifications are the locations of the network users.

25. The system of claim 14, wherein the proxy server comprises a mobile gateway and a privacy agent,

wherein the privacy agent determines if the network users want to block their identities, and if so, translates the identities of the network users into dummy identifications, and

wherein the privacy agent contains the memory storage and stores relationships between the identities and the dummy identifications in the memory storage.

26. The system of claim 14, wherein the location system comprises a location agent that determines the locations of the network users and a location monitor in communication with the location agent, wherein the location monitor determines if the locations of the network users match a specific location requested by the plurality of web sites.

27. A proxy server for providing an anonymous location service for use in a wireless network that tracks locations and identities of network users, the proxy server comprising:
