    摘要: A communication system comprises a first plurality of remote stations (107, 109, 111) belonging to a first call group (119) having an associated first encryption key and a first encryption mode. A second plurality of remote stations (113, 115) belongs to a second call group (121) having an associated second encryption key and a second encryption mode. A group controller (117) forms a third call group (123) which comprises the first and the second call groups (119, 123) and which has an associated third encryption key. When communicating on the third, combined call group, the first plurality of remote stations (107, 109, 111) use the third encryption key and the first encryption mode whereas the second plurality of remote stations (113, 115) use the third encryption key and the second encryption mode.
