Abstract: A method of generating relevant promotional materials for transmission to a mobile device includes receiving a query from the mobile device, identifying a plurality of advertisements associated with an advertiser-directed delivery parameter that match parameters for the mobile device, and generating a response to the query comprising search results and the plurality of advertisements.

Abstract: A computer-implemented method of identifying illegitimate requests for information may include associating a first carrier with an electronic promotional item, receiving a request relating to the electronic promotional item from a second carrier, and identifying the request as illegitimate if the first carrier is different than the second carrier. The computer-implemented method may further include transmitting the electronic promotional item to the first carrier. The request may be a response to the electronic promotional item. In some embodiments, the electronic promotional item may be a link to more information about the electronic promotional item. The computer-implemented method may further include logging the request in a database and charging an ad sponsor for the request in the second database. In some embodiments, a charge may be canceled for the request if the request is identified as illegitimate.

Abstract: In an Interactive Real-Time Distributed Navigation system a method and system is disclosed for implementing a warm start/cold start option. Through selection of the warm start option, an interactive session for providing navigational directions to a user is more quickly established because a user's position is assumed not to be ambiguous. A method of the invention verifies this assumption. Through selection of the cold start option, the method of the invention seeks to remove ambiguity in a user's position before providing navigational directions. If, however, a user's position is not ambiguous, the method of the invention reverts to a warm start condition to immediately transmit navigational directions to the user.
