Abstract
In a communication system, a wireless communication device receives and processes a text message including a location request code and a communication code. In response to the location request code, the wireless communication device transfers a location query indicating the communication code. An authorization computer system receives the location query and processes the communication code to determine if the location request should be authorized. If the location request should be authorized, the authorization computer system transfers a location authorization. The wireless communication device processes the location authorization, and in response, transfers geographic location information using the communication code to control delivery of the geographic location information to a location receiving system.
