Patent Images
1. An analog cellular radiotelephone system for communicating analog voice messages via radio channels to and from one or more mobile voice units, and additionally communicating user data via one or more of the radio channels, the system comprising:
- a mobile data unit operable for communicating user data via said one or more radio channels; and
a base station comprising;
one or more voice transceiver means for transmitting and receiving analog voice communications to and from said one or more mobile voice units;
a data transceiver means for transmitting and receiving a plurality of digital data packets to and from said mobile data unit; and
a base site controller comprising a means for establishing a packet data circuit-switched connection between the mobile data unit and a data end system, a means for establishing a packet-switched data transfer channel between the mobile data unit and the data end system, and means for determining when to establish the packet data circuit-switched connection and when to establish the packet-switched data transfer channel.
