ABSTRACT:
In an exemplary communications system a multiplicity of mobile terminals are to share a communications link with a primary processor. The primary processor may transmit a multiterminal polling signal defining a series of successive response time slots which the terminals may randomly select. A terminal wishing to send a message transmits a brief response burst in the selected time slot giving its identification. The primary processor may then sequentially poll specific individual terminals having messages to send. The primary processor may maintain a record of currently active terminals and/or of collisions (where more than one terminal seeks to transmit in the same response time slot), and as needed may automatically send e.g. with its multiterminal poll, a time slot number change, creating a greater or lesser number of time slots for future use by the active terminals. The system is thus highly adaptable on a dynamic basis during operation so as to readily maintain optimum throughput under changing conditions. As a consequence additional terminals may become active simply by transmitting their respective identifications in randomly selected response time slots. The multiterminal poll may include a listing of one or more terminals for which the primary processor has a message so that the primary processor may be assured that such terminal is available (as indicated by its response in a random time slot) before a lengthy message is sent.
