Abstract
Methods and apparatus for delivering personalized (e.g., contextual) messages to a user that meets certain geographic, affiliation/metadata, timing, and/or or other criteria. These messages are geographically and logically persistent, and can be left by members of the user's social or 'buddy' network, individuals, institutions, the user's service provider(s), or even advertisers or others seeking a commercial opportunity. These messages can be rendered in the form of voice, video, audio (e.g., MP3), text and graphics delivered to mobile phones, PDA's or other devices with network connectivity. Exemplary embodiments of the invention incorporate existing geo-localization technologies such as GPS embedded in these mobile platforms, or triangulation via signals from the cellular/PCS networks, IP addressing, presence in ad hoc networks, cell ID, E911/E112, Time of Arrival (TOA), Time Difference of Arrival (TDOA), Observed Time Difference (OTD) and Angle of Arrival (AOA).
