A wireless communications system is presented where a mobile station is
able to automatically determine its proximity to a second mobile station
or landline telephone. Once the proximity determination command has been
given, no further actions are required by the users of either telephone.
A GPS receiver connected to the first mobile station is able to provide
that mobile with its position and direction. The first mobile station
makes a request to the other telephone for its position, through SMS
messaging for example. A GPS receiver connected to the second mobile
station is able to provide the second mobile station with data to enable
the position request. Trust determinations can be enabled so that
position data is sent to a restricted list of requesting telephone
numbers. Likewise, the second mobile station can request position data
from the first mobile station. When position information is requested
from a landline telephone, the request can be fulfilled by the landline
telephone service provider. A method for automatically exchanging
position information is also provided.
