The spatial-related information may be obtained by using positioning tracking systems such as a global positioning system, whereas the non-spatial related information may include communication activities associated with the mobile computing device, such as phone calls, e-mails, text messages, pages, etc. The present invention also provides methods and apparatus of sharing event information between mobile communication devices as well as related navigational information for traveling to an event from a real-time position of a mobile communication device. ## Claims ### Claim 1 A method of searching for time-stamped meta data, comprising: receiving, at a physical server, current location information respectively associated with each of a plurality of mobile communication devices; performing a search using said current location information to retrieve time-stamped meta data associated with said current location information respectively associated with each of said plurality of mobile communication devices; and determining a duration of each stop within said retrieved time-stamped meta data. ### Claim 2 (depends on 1) The method of searching for time-stamped meta data according to claim 1, wherein: said meta data includes a stop condition. ### Claim 3 (depends on 1) The method of searching for time-stamped meta data according to claim 1, wherein: said meta data includes an email message. ### Claim 4 (depends on 1) The method of searching for time-stamped meta data according to claim 1, wherein: said meta data includes a digital image. ### Claim 5 (depends on 4) The method of searching for time-stamped meta data according to claim 4, wherein: said digital image overlaps with associated location information. ### Claim 6 (depends on 1) The method of searching for time-stamped meta data according to claim 1, further comprising: determining, for at least one of said plurality of mobile communication devices, using said retrieved time-stamped meta data, a number of stops made by each of said plurality of mobile communication devices, a duration of each of said stops, and a duration of travel time between consecutive stops. ### Claim 7 (depends on 1) The method of searching for time-stamped meta data according to claim 1, further comprising: determining a total travel time and a total stop time for at least one of said plurality of mobile communication devices, using said retrieved time-stamped meta data, a duration of a stop, and a duration of travel time, for said each of said plurality of mobile communication devices. ### Claim 8 (depends on 7) The method of searching for time-stamped meta data according to claim 7, further comprising: determining a distance traveled between two consecutive stops for at least one of said plurality of mobile communication devices. ### Claim 9 (depends on 7) The method of searching for time-stamped meta data according to claim 7, further comprising: determining an average speed of at least one of said plurality of mobile communication devices during a duration of travel time of said at least one of said plurality of mobile communication devices. ### Claim 10 (depends on 1) The method of searching for time-stamped meta data according to claim 1, further comprising: planning a route, for at least one of said plurality of mobile communication devices. ### Claim 11 (depends on 1) The method of searching for time-stamped meta data according to claim 1, further comprising: forwarding said retrieved time-stamped meta data to another mobile communication device distinct from a one of said plurality of mobile communication devices associated with said time-stamped meta data. ### Claim 12 (depends on 1) The method of searching for time-stamped meta data according to claim 1, wherein: said plurality of mobile communication devices are each a cellular telephone. ### Claim 13 (depends on 1) The method of searching for time-stamped meta data according to claim 1, wherein: said current location information is Global Positioning System (GPS)-derived location information.
