1. A communication method for controlling a mobile transceiver which may communicate with a communication network controlled by a computer, the network including a plurality of base transmitters for transmitting messages from the network to the mobile transceiver and base receivers for receiving messages from the mobile transceiver, the mobile transceiver being capable of sending registration signals to be received by a base receiver in the network to allow the network to identify the mobile transceiver'"'"'s approximate location according to the location of the base receiver(s) that received the registration signals and being capable of sending a message acknowledgment signal when the mobile transceiver receives a message from the network to indicate successful delivery of the message, and the plurality of base transmitters in the network being capable of sending a probe signal to the mobile transceiver to cause the mobile transceiver to transmit a probe acknowledgment signal to be received by a base receiver in the network to allow the network to identify the mobile transceiver'"'"'s approximate location according to the location of the base receiver that received the acknowledgment signal, the method comprising the steps of:

  • (a) sending a message from the network to the mobile transceiver to disable the mobile transceiver'"'"'s capability to transmit registration signals;

    (b) storing in the network the number of probe signals sent by the network to the mobile transceiver during a first period of time and the number of messages successfully delivered to the mobile transceiver by the network during a second period of time;

    (c) determining a likelihood that a probe signal will be required to be sent by the network to deliver a message by evaluating the stored number of probe signals and stored number of messages successfully delivered; and

    (d) sending a message to the mobile transceiver to enable the mobile transceiver'"'"'s capability to transmit a registration signal if the calculated likelihood exceeds a selected value.
