Abstract
Systems and methods related to maintaining a signaling link between network terminals in a communications network. Periodic receiver ready frames are transmitted from a first terminal to a second terminal when there are no data frames to be transmitted. A temporal period is determined during which a predetermined condition will affect communications with the second terminal; the predetermined condition can be, for example, a period during which the sun will be within a predetermined subtended angle of an antenna associated with the second terminal. The second terminal transmits a pause frame to the first terminal prior to the temporal period; the pause frame includes the identification of the temporal period. The first terminal then pauses the transmission of data frames and the periodic receiver ready frames during the temporal period, and resumes the transmission of data frames and periodic receiver ready frames subsequent to the expiration of the temporal period, whereby it is unnecessary to re-establish a signaling link between the first and second terminals upon the expiration of the temporal period.
