Abstract

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.

Claims

1. A telecommunications system comprising a primary station for transmitting downlink messages on a downlink and at least one secondary station for transmitting signals on an uplink, wherein the primary station includes in a downlink message indicia indicating status information associated with the downlink message to be transmitted on the uplink by the at least one secondary station in a status message when said status information is affected by an action taken at the secondary station, and the at least one secondary station comprises means for recovering the downlink message and said indicia, means for displaying the downlink message and for displaying the indicia as representations of one or more icons, means responsive to an action being taken at the secondary station affecting the status information, for transmitting a signal on the uplink including a status message indicating the affected status information and for altering the representation of at least one of the icons.

2. A system as claimed in claim 1, wherein said means responsive to a user of the secondary station taking an action affecting the status information alters the representation of the at least one of the icons by showing the at least one of the icons in reverse video format.

3. A system as claimed in claim 1, wherein the one or more icons are displayed in a reserved area of a display screen which is separate from a message display area.

4. A system as claimed in claim 1, wherein the icons are displayed in a tabular form.

5. A system as claimed in claim 1, data representative of the one or more icons is stored with the associated downlink message, said data representative of the icons being recalled each time the associated downlink message is displayed and the icons are erased when the associated message is erased.

6. A system as claimed in claim 1, wherein there are a plurality of different types of downlink messages, and said indicia distinguishes one message type from another.

11. A system as claimed in claim 2, wherein the one or more icons are displayed in a reserved area of a display screen which is separate from a message display area.

12. A system as claimed in claim 2, wherein the icons are displayed in a tabular form.

13. A system as claimed in claim 2, data representative of the one or more icons is stored with the associated downlink message, said data representative of the icons being recalled each time the associated downlink message is displayed and the icons are erased when the associated message is erased.

14. A system as claimed in claim 3, wherein data representative of the one or more icons is stored with the associated downlink message, said data representative of the icons being recalled each time the associated downlink message is displayed and the icons are erased when the associated message is erased.

15. A system as claimed claim 4, wherein data representative of the one or more icons is stored with the associated downlink message, said data representative of the icons being recalled each time the associated downlink message is displayed and the icons are erased when the associated message is erased.

16. A system as claimed in claim 11, wherein data representative of the one or more icons is stored with the associated downlink message, said data representative of the icons being recalled each time the associated downlink message is displayed and the icons are erased when the associated message is erased.

7. A secondary station for use in a telecommunications system in which a primary station transmits a downlink message on a downlink together with indicia indicating status information associated with the downlink message to be transmitted on the uplink by the secondary station in a status message when said status information is affected by an action taken at the secondary station, wherein the secondary station comprises means for recovering the downlink message and said indicia, means for displaying the downlink message and for displaying the indicia as one or more representations of icons, means responsive to an action being taken at the secondary station affecting the status information, for transmitting a signal on the uplink including a status message indicating the affected status information and for altering the representation of at least one of the icons.

8. A secondary station as claimed in claim 7, wherein the icons are displayed separately from the message.

9. A secondary station as claimed in claim 7, wherein said means responsive to a user of the secondary station taking an action affecting the status information alters the representation of the at least one of the icons by showing the at least one of the icons in reverse video format.

10. A secondary station as claimed in claim 7, further comprising storage means for storing data representative of the icons together with the associated downlink message.

17. A secondary station as claimed in claim 8, wherein said means responsive to a user of the secondary station taking an action affecting the status information alters the representation of the at least one of the icons by showing the at least one of the icons in reverse video format.

18. A secondary station as claimed in claim 8, further comprising storage means for storing data representative of the icons together with the associated downlink message.

19. A secondary station as claimed in claim 9, further comprising storage means for storing data representative of the icons together with the associated downlink message.

20. A secondary station as claimed in claim 17, further comprising storage means for storing data representative of the icons together with the associated downlink message.
