A pull communication system enables a call from a calling party to a called party to be completed directly, irrespective of the location of the called party within a cellular telephone system. In a preferred embodiment, a calling signal is directed to a pull central office that creates switching information used to connect the called party to the calling party. The pull central office includes a switch for receiving the calling signal at a first port. The pull central office also includes a switch controller in communication with the switch, the switch connecting the switch controller to the calling signal. The switch controller obtains a called party identifier from the calling party. The switch controller creates a call request signal that includes the switching information and the called party identifier. The switch controller causes a switch transmitter to transmit the call request signal to the called party, and when the called party responds with a call acceptance signal at a second port, connects the second port to the first port, thereby completing the call. The pull communication system includes a receiving cellular telephone that includes a receiver for receiving the call request signal from the pull central office. The receiving cellular telephone also includes a pull controller that receives and decodes the call request signal.
