A system for transmitting long text messages includes a plurality of transmission cells defining different geographical areas, each having a transmitter for simulcast address transmission at a first data bit rate and for transmitting the address and a message at a second data bit rate higher than the first data bit rate. A paging transceiver generates and transmits an acknowledgment signal in response to receiving a transmitted address at the first data bit rate. Receivers located within each of the transmission cells receive the transmitted acknowledgment signal. An apparatus responsive to the received acknowledgment signal identifies the transmission cell in which the paging transceiver is located effecting the selection of the transmitter in the transmission cell in which the paging transceiver is located to transmit the address and message at the second data bit rate higher than the first data bit rate.

A method for transmitting a message to a paging transceiver in a communication system comprising a plurality of transmission calls defining different geographical areas, each transmission cell having a transmitter for transmitting an address identifying the paging transceiver and the message, and a receiver for receiving an acknowledgement signal generated by the paging transceiver, said method comprising the steps of: transmitting the address at a first data bit rate, the address being simulcast from the transmitters located within each of the plurality of transmission cells; transmitting the acknowledgement signal from the paging transceiver in response to having received the address; receiving the acknowledgement signal by at least one receiver located within the plurality of transmission cells; identifying the transmission cell in which the paging transceiver is located from the received acknowledgement signal; and selecting the transmitter in the transmission cell in which the paging transceiver is located for transmitting the address and the message at a second data bit rate higher than the first data bit rate.
