A mobile station () in a satellite mobile telephone system predicts when it will move into another cell on the basis of one set of broadcast information thereby reducing the overall processing burden. The mobile station () can predict with a useful degree of certainty which broadcast control channel (BOCH) frequencies it should listen on when it wakes up on the basis of a stored map of the relative positions of cells. The broadcast information is valid for a predetermined time interval. Upon waking up, the mobile station () determines present time within the predetermined time interval and uses the broadcast information as well as the present time within the predetermined time interval to predict the time at which the mobile telephone will leave the cell.

Satellite mobile telephone cell departure prediction

A mobile station () in a satellite mobile telephone system predicts when it will move into another cell on the basis of one set of broadcast information thereby reducing the overall processing burden. The mobile station () can predict with a useful degree of certainty which broadcast control channel (BCCH) frequencies it should listen on when it wakes up on the basis of a stored map of the relative positions of cells. The broadcast information includes information about the current cell's () shape (V, V, V, V, V, V) and translational (T) and rotational (R) motion.

An antenna assembly comprises a panel (1) with suckers (3) for mounting it to a window or other vertical surface. A foil antenna (2) is formed on the panel (3). The antenna (2) may be coupled to a transceiver (8) by a feeder (6) so that in use it replaces the transceiver's own antenna. In another arrangement, the antenna may simply re-radiate radio signals transmitted by the transceiver using its own antenna.
