telephone network or for a call placed by a mobile terminal coupled to a satellite of the
system. (Id. at 13.)
A blockage by a building or tree may render a mobile terminal "disadvantaged,"
(id. at 3); the appellants' invention is aimed at transmitting messages to such a terminal.
(Id at 9.) More specifically, a mobile terminal receives a communication from a base
station via a first channel; the communication indicates a pending message. If
disadvantaged, the terminal monitors a second channel identified in the communication.
Upon determining that the terminal is disadvantaged, the base station broadcasts the
pending message to the terminal via the second channel. (Id., abs.) A further
understanding of the invention can be achieved by reading the following claim.
1. A method of communicating radiotelephone messages from a base
station to a remote, disadvantaged user terminal having an identifier
associated therewith, the method comprising the steps of:
broadcasting from the base station to the user terminal the
associated terminal identifier along with an indication of a pending
message on a first forward-only radiotelephone channel;
determining if the user terminal is disadvantaged; and
responsive to determining that the user terminal is disadvantaged,
broadcasting the message from the base station to the user terminal on a
second forward-only radiotelephone channel, wherein the second
forward-only radiotelephone channel is identified with the indication of a
pending message via the first forward-only radiotelephone channel.
