Anforderung und Darstellung von Information über das Status von Nachrichten in einer Mobileinheit eines bidirektionalen Telekommunikationssystems

摘要

A two-way telecommunications system includes a primary station (10, 14, 16) and a secondary station (18, 20). The primary station is arranged for transmitting on a downlink a data message together with indicia representative of status messages it wants to receive from the secondary station. The secondary station in response to the indicia represents the desired status items as icons and when the user has taken an action affecting the status, it transmits a status message on the uplink and changes the representation of the icon. The icons are stored with the message until the latter is erased.
