Patent ID: 8203991

Claim:
A communication device comprising: a first communication system for transmitting and/or receiving signals according to a first protocol; a second communication system for transmitting and receiving signals according to a second protocol, the second protocol having the facility that a receiver can indicate to a transmitter that it is in an unresponsive state whereby the transmitter can be inhibited from transmitting data to the receiver when it is in the unresponsive state; a signal activity detector for detecting activity in the signals of the first protocol; a signal activity predictor responsive to the signal activity detector for predicting activity in the signals of the first protocol, in accordance with a predictive algorithm to which inputs are applied from said signal activity detector; and a control unit responsive to the signal activity detector via the signal activity predictor for causing the second communication system to transmit one or more signals to indicate that it is in an unresponsive state when the first protocol is predicted to be active.
