Methods and apparatus for gathering, organizing and displaying contact
information in a mobile communications network. In one embodiment, a
method for operating a mobile communication network includes an
information server and a mobile communications device coupled to the
service via a wireless connection. The method comprises transmitting a
location identifier message including a current location from the mobile
communications device to the server via the wireless link. The mobile
device also transmits a list of contacts to the server via the wireless
link. The contacts are matched with the location using a location
database maintained for other mobile communications devices in order to
generate a list of proximate users. Alternatively, the contact list can
be based upon cognitive or psychographic proximity (versus merely
physical proximity). The list of proximate users is transmitted to the
mobile communications device, and the list is displayed in an easily
perceived fashion based on user preferences.
