ABSTRACT:
A callback service for completing a call from a calling party to a mobile station of a called party that was not previously completed due to no response. After the call was not completed due to no response, the mobile station is monitored to determine if it has moved, and when movement is determined to have occurred, a callback is initiated between the calling party and the called party. The movement is a good indication that the called party has moved the mobile station and may therefore be available to receive the call. The movement of the mobile station is preferably determined by detecting that the mobile station has changed its location utilizing mobile positioning technology. The service will generally result in more calls being completed and in their being completed in less time.
