Abstract

It is determined whether a location of a mobile device is within a coverage region of a first information service. Communications for the first information service are redirected to a second information service when the location of the mobile device is not within a coverage region of the first information service. The second information service generally has a coverage region encompassing the location of the mobile device. Communications betwee n a mobile device and a first information service are redirected to another information service when properties of the new information service are determined to meet predetermined criteria set by a user of the mobile device , by an application, or both. In yet another aspect of the invention, Replacement of information services can be "aggressive" or "non-aggressive." Communications between a mobile device and an original information service a re redirected to another information service when the original information service fails.
