Abstract
An integrated voice and packet data telecommunications system has at least one dual mode channel. The system comprises a plurality of transceivers, at least one transceiver being operable to transmit and receive voice traffic on the dual mode channel, and at least one transceiver being operable to transmit and receive packet data traffic on the dual mode channel. The system further comprises a controller for controlling the transceivers so as to allocate the dual mode channel either to voice communications or to packet data communications. The controller responds to changing demand for voice channels and packet data channels by changing dynamically the allocation of the dual mode channel. The system is particularly useful for providing Cellular Digital Packet Data (CDPD) services.
