A wireless telephone subscriber who wishes directory assistance in the form of directions from one specified location to another is connected to a directory assistance agent. The subscriber identifies a destination location and any requested travel criteria. The directory assistance agent collects the subscriber's travel parameters and a routing algorithm on the server draws upon geographic, transportation, and related information stored on the server to generate an appropriate route to the destination location. The selected route may be divided into multiple segments. Directions according to each segment are provided to the subscriber. The subscriber may remain connected to the directory assistance center for all or any portion of the travel, may disconnect and reconnect as necessary, or may receive the entire route of travel in a single communication. Upon reconnection to a directory assistance agent while travelling, the subscriber is recognized as a travelling subscriber based on his MIN, ESN, or unique traveller identification number, and the agent is furnished with the subscriber's travel information and current location. The route of travel may be updated or amended as desired or as made necessary due to closed routes of travel, congestion, etc. |
