The present invention provides a computer-implemented method, system, and program product for tracking a location of a user of a wireless device in a private network environment. Specifically, under the present invention, a wireless device user will form a data connection with a private network through a public network such as the Internet. At such a time "location" information will be communicated from the wireless device to the provider of the private network, which will use the information to track the location of the wireless device user. In addition, the provider of the private network can query the wireless device when updates to the information are desired. At this or any other time, the wireless device can be queried for any such updates.
