<p>The present invention relates to a device (4, 5, 6, 7, 8) adapted for transmission and reception via a satellite link (2) in a satellite communication system (3). The device (4, 5, 6, 7, 8) is further a part of a group (9, 21) of similar devices (4, 5, 6, 7, 8), where the device (4, 5, 6, 7, 8) comprises a first address (14), unique for the device (4, 5, 6, 7, 8). The device (4, 5, 6, 7, 8) further comprises at least a second address (15, 19) that is common for the group (9, 21), enabling a message (22a, 22b, 22c) sent to the group (9, 21) to be addressed to the group (9, 21). This means that a single transmission is sufficient to reach all members (4, 5, 6, 7, 8) in the group (9, 21). The present invention also relates to a satellite communications system comprising devices according to the above. The present invention also relates to a method for transmission and reception via a satellite link.</p> |
