PCT No. PCT/SE97/00502 Sec. 371 Date Dec. 29, 1998 Sec. 102(e) Date Dec. 29, 1998 PCT Filed Mar. 24, 1997 PCT Pub. No. WO97/41705 PCT Pub. Date Nov. 6, 1997An access method using a rotating lobe in a telecommunication system that has antennas that support a number of horizontal lobes for communication between a base station and a mobile station. Signals to and from the antennas are modulated by a lobe shaping unit to bring the lobe to rotate in a horizontal plane, that the mobile station synchronizes with the base station transmission lobe by means of an internal clock, and after achieving synchronization goes into a sleep mode. The sleep mode has a number of wake up levels, wherein the mobile station in the deepest level listens for wake up calls and in the highest level listens for the proper message. |
