CONTROLLING ATTENUATION OF AN ANTENNA SIGNAL IN A COMMUNICATION TERMINAL TO REESTABLISH A LOST COMMUNICATION LINK
First Claim
1. A method comprising:
- establishing a wireless communication link between first and second communication terminals and exchanging communication signals therebetween;
controlling the first communication terminal to continue over time to increase a power level at which it transmits communication signals to the second communication terminal in response to detecting loss of the wireless communication link and while continuing attempts to reestablish the communication link with the second communication terminal; and
controlling the first communication terminal, in response to detecting loss of the communication link, to increase a level of attenuation that it applies to communication signals from the second communication terminal, and to then more gradually decrease the level of attenuation over time in response to continuing attempts to reestablish the communication link with the second communication terminal.

Abstract
Some embodiments of the present invention are directed to methods of operating communication terminals. A wireless communication link is established between first and second communication terminals and communication signals are exchanged therebetween. The first communication terminal is controlled to continue over time to increase a power level at which it transmits communication signals to the second communication terminal in response to detecting loss of the wireless communication link and while continuing attempts to reestablish the communication link with the second communication terminal. The first communication terminal is further controlled, in response to detecting loss of the communication link, to increase a level of attenuation that it applies to communication signals from the second communication terminal, and to then more gradually decrease the level of attenuation over time in response to continuing attempts to reestablish the communication link with the second communication terminal.

14. A communication terminal comprising:
-
a RF receiver circuit that is configured to receive communication signals from another communication terminal through a wireless communication link; a controller that is configured to respond to detecting loss of the communication link by increasing a level of attenuation that is applied to communication signals from the other communication terminal, and by then more gradually decreasing the level of attenuation over time in response to continuing attempts to reestablish the communication link with the other communication terminal. - View Dependent Claims (15, 16, 17, 18, 19, 20)
