Abstract

Methods and devices are described for providing localized secure navigation in conjunction with near field communication access control systems. In one potential embodiment, a mobile device such as a cell phone may communicate with a door access control point using near field communication to receive location access system information. The mobile device may then authorize download and execution of a local secure navigation module from a location access system using the location access system information for use in receiving location assistance data, based on an authentication level associated with the mobile device. Such location assistance data may be used by the local secure navigation module to provide location assistance when the mobile device is in a secure location. The location of the mobile device may then be tracked using at least the location assistance data and the communication with the door access control point.

automatically deleting the local secure navigation module and the location assistance data from the mobile device in response to the determining that the mobile device is outside of the secure location.

8. The method of claim 7, wherein determining that the mobile device is outside of the assistance area comprises communicating, with an exit door access control point, a request to exit a secure area.

9. The method of claim 1, further comprising:

communicating, using the near field communication module, with a second door access control point to receive second location access system information; and

receiving updated location assistance information from the location access system in response to the communication with the second door access control point.

10. The method of claim 9 wherein receiving updated location assistance information comprises receiving second map information for a second area;

and

deleting first map information for a first area received as part of the location assistance data.

11. The method of claim 1 wherein the location access system information comprises an interne protocol address for a location system server;

and

wherein receiving location assistance data at the mobile device comprises communicating with a location access server via a wireless network access point.

12. The method of claim 1 wherein tracking a location of the mobile device using at least the location assistance data comprises using a known location of the door access control point with network assisted positioning information from a plurality of wireless network access points to track the location of the mobile device.

13. The method of claim 1 wherein tracking a location of the mobile device using at least the location assistance data comprises using a known location of the door access control point and map information with accelerometer data from an accelerometer to track a location of the mobile device.

14. A mobile device comprising:

means for near field communication with a door access control point to receive location access system information;

means for authorizing download and execution of a local secure navigation module from a location access system;

means for receiving location assistance data, based on an authorization level, wherein the location assistance data is used by the local secure navigation module to provide location assistance when the mobile device is in a secure location; and

means for tracking a location of the mobile device using at least the location assistance data.

15. The mobile device of claim 14 further comprising:
