System and method for sharing location data in a wireless communication network
Abstract:
A system and method for sharing location data amongst wireless communication devices uses a token system to grant permission to share location data. The tokens may be created automatically as the result of user activation of a different function. Location data may be exchanged when two wireless communication devices, authorized to exchange location data, are within a predetermined distance from each other. Location data may also be automatically exchanged upon the occurrence of a scheduled calendar event within a wireless communication device. Location data may be exchanged a single time or can be exchanged on a continuous or periodic basis so long as the token still exists. The token may be destroyed manually by some user activity or may be terminated automatically.
