Abstract
A two way communications path is established between a pager device and a paging service provider. The pager device generates a control command for the paging service provider, converts the control command into signals recognizable by a telephone network, and transmits the signals to the paging service provider over the telephone network. The paging service provider receives the signals from the pager device over the telephone network, generates one or more messages for the pager device in response to these signals, and sends the message(s) to the pager device over a wireless paging network. The pager device receives the message(s) over the wireless paging network.
