Abstract
A communication system includes mobile units, a network switching center, and service centers to provide a variety of enhanced services to the mobile units. The service centers and/or the network switching centers determine directions from an origination location to a destination location. The directions, which may comprise multiple segments separated by separator signals, are communicated to the mobile unit using a communication network. The mobile unit may present each segment of the directions to a user. In one embodiment, the mobile unit generates a service message specifying an origination location and a destination location. The directions are determined in response to the service message.
