Abstract
A method is disclosed, and an apparatus described, for providing a console display indicating the incompatibility of a subscriber with a talk group in an RF communication system. The console provides a first display as long as the system detects no subscriber incompatibility with a talk group. When the system determines the subscriber is incompatible with a talk group, however, the console provides a second display which is graphically distinct from the first display. The second display is further arranged so the incompatible subscriber can readily be identified.

Description
Background of the Invention
This invention pertains to trunked radio frequency (RF) communication systems or, more particularly, to a method of displaying subscriber incompatibilities with talk groups in trunked RF communication systems.
Modern-day radio frequency (RF) trunked communication systems can be understood with reference to FIGS. 1A and FIG. 1B, which depicts a typical RF communication system (100) arranged with a console (5). As shown, the RF communication system (100) includes fixed equipment (4) arranged to facilitate communication between several subscribers 1 (1), 2 (2) and 3 (3). The console (5) is equipped with a display (6) and connected to the fixed equipment by means of a first suitable link (7). Also shown is a computerized controller (8) connected to the console by means of a second suitable link (9) and connected to the fixed equipment by means of a third suitable link (10).
Those skilled in the art will appreciate that one of the functions of the console typically is to assign subscribers to talk groups. Once a particular subscriber is a member of a particular talk group, the subscriber can readily communicate with other subscribers in the same talk group. Referring to the figure, subscribers 2 and 3, depicted in FIG. 1B, are members of talk group A (11), whereas subscriber 1, depicted in FIG. 1A, is not.
Those skilled in the art will appreciate that not all subscribers are compatible with all talk groups. For example, assume subscribers 2 (2) and 3 (3) are capable of data communication, while subscriber 1 (1) is not. Assume also that talk group A (11) has been established for the sole purpose of supporting a data communication session. In this example, subscribers 2 (2) and 3 (3), being capable of data communication, may be members of talk group A (11), as shown, while subscriber 1 (1), being incapable of data communication, cannot be a participating member of talk group A (11).
With modern RF communication systems becoming increasingly large and complex, those skilled in the art will appreciate that, from time to time, a console operator may inadvertently assign an incompatible subscriber to a talk group. Those skilled in the art will also appreciate that, even though a console operator may initially assign a compatible subscriber to a talk group, the subscriber may later become incompatible with the talk group due to subsequent re-arrangements or changes made within the system.
As a result, the inventor has discovered it is difficult for operators of modern RF communication systems to administer the compatibility of a substantial number of subscribers with a corresponding number of talk groups. While prior RF communication systems have provided computerized control systems that enabled the console operator to determine the compatibility of a subscriber with a talk group, the inventor has discovered it would be particularly useful if the RF communication system provided a console display of the compatibility of a subscriber with a talk group.
Summary of the Invention
Therefore, according to the invention, a method is provided and an apparatus described for providing a console display indicating the compatibility of a subscriber with a talk group in a RF communication system.
In the preferred embodiment, the console provides a first display including a symbol representing the subscriber (the "first subscriber symbol") and a symbol representing the talk group (the "first talk group symbol"). With this arrangement, the first subscriber symbol is displayed within the first talk group symbol whenever the subscriber is assigned to the talk group.
The console provides a second display whenever the subscriber is a member of the talk group and the subscriber is, or becomes, incompatible with the talk group. This second display includes a symbol representing the subscriber (the "second subscriber symbol") and a symbol representing the talk group (the "second talk group symbol"), with the second subscriber symbol displayed within the second talk group symbol. The console may also provide an audible signal, such as a gong, buzzer or bell, to alert the console operator to the presence of the second display.
Further, the second display presents the second subscriber symbol as a highlighted version of the first subscriber symbol of the first display to graphically indicate to the console operator that the associated subscriber is presently incompatible with the talk group. Also, the second display presents the second talk group symbol as a reverse-video version of the first talk group symbol of the first display to graphically indicate to the console operator that the associated talk group presently contains an incompatible subscriber.

Detailed Description of the Invention
The subscriber incompatibility display arrangement is shown in FIGS. 2, 3, 4 and 5. In what follows, it will be assumed that a hypothetical RF communication system having a console and subscriber i and talk group A is arranged with the present invention.
Referring to FIG. 2, the figure shows a display similar to that which the operator would see at a point in time when subscriber 1 is not a member of talk group A. This display is arranged to indicate that subscriber 1 is not a member of talk group A.
In FIG. 2, subscriber 1 is represented by the numeral 1 (12) and talk group A is represented by the rectangle labelled "Talk Group A" (13). The fact that subscriber 1 is not a member of talk group A is indicated here by the numberal 1 (12) representing subscriber 1 being situated outside the rectangle labelled "Talk Group A" (13) representing talk group A.
Referring to FIG. 3, the figure shows a display similar to that which the operator would see at a point in time when subscriber 1 is a member of talk group A and the system has not determined that subscriber 1 is presently incompatible with talk group A. This display is arranged to indicate that subscriber 1 is a member of talk group A.
In FIG. 3, subscriber i is represented by the numeral 1 (14) and talk group A is represented by the rectangle labelled "Talk Group A" (15). The fact that subscriber 1 is a member of talk group A is indicated here by the numeral 1 (14) representing subscriber 1 being situated inside the rectangle labelled "Talk Group A" (15) representing talk group A.
Referring to FIG. 4, this figure shows a first embodiment of a display similar to that which the operator would see at a point in time when subscriber 1 is a member of talk group A and the system has determined that subscriber 1 is presently incompatible with talk group A. This display is arranged to indicate that subscriber 1 is a member of talk group A and that subscriber 1 is incompatible with talk group A.
In FIG. 4, subscriber 1 is represented by the numeral (16) and talk group A is represented by the rectangle labelled "Talk Group A" (17). The fact that subscriber 1 is a member of talk group A is indicated here by the numeral I (16) representing subscriber 1 being situated inside the rectangle labelled "Talk Group A" (17) representing talk group A. The fact that subscriber 1 is incompatible with talk group A is indicated here by the numeral 1 (16) representing subscriber 1 being highlighted.
Referring to FIG. 5, this figure shows a second embodiment of a display similar to that which the operator would see at a point in time when subscriber 1 is a member of talk group A and the system has determined that subscriber 1 is presently incompatible with talk group A. This display is arranged to indicate that subscriber I is a member of talk group A and that subscriber 1 is incompatible with talk group A.
In FIG. 5, subscriber 1 is represented by the numeral 1 (18) and talk group A is represented by the rectangle labelled "Talk Group A" (19). The fact that subscriber 1 is a member of talk group A is indicated here by the numeral 1 (18) representing subscriber 1 being situated inside the rectangle labelled "Talk Group A" (19) representing talk group A. Also, the fact that subscriber 1 is incompatible with talk group A is indicated here by the numeral 1 (18) representing subscriber 1 being highlighted.
This display is further arranged to indicate that talk group A contains an incompatible subscriber by the rectangle labelled "Talk Group A" (19) representing talk group A being presented in reverse video. This reverse-video presentation of the rectangle labelled "Talk Group A" (19), coupled with the highlighted presentation of the numeral 1 (18), also provides a more graphical indication that subscriber 1 is incompatible with talk group A.
