VERFAHREN UND VORRICHTUNG FÜR DIE STATUSSYNCHRONISATION EINER GRUPPE VON FUNKRUFEMPFÄNGERN
Kind Code:
C5


Abstract:

A method of synchronizing message information (208) among a plurality of transceivers (130, 150) comprising the steps of:
transmitting (200) by a wireless messaging infrastructure a first message (205) having a first status;
in one transceiver (130) of the plurality of transceivers, changing (220) the first status of the first message to a second status responsive to an input to the one transceiver, and transmitting (235) a second message (240) indicative of the second status;
in the wireless messaging infrastructure (110), receiving (245) the second message;
and
characterised in that the method includes
the steps of in the wireless messaging infrastructure, responsive to receiving the second message transmitting (250) a third message (255) indicative of the second status; and
in at least one other transceiver (150) of the plurality of transceivers, receiving (265) the third message and responsive to receiving the third message, changing (275) the first status of the first message to the second status;
said step of transmitting (235) the second message indicative of the second status in the one transceiver (130) further comprises the steps of:
delaying (230) transmission of the second message by a predetermined time period after changing (220) the first status of the first message in order to reduce the number of status change transmissions;
changing (220) the second status of the first message to a subsequent status in response to a subsequent input to the one transceiver; and
transmitting (235) the subsequent status as the second status if changing of the second status to the subsequent status occurs within the predetermined time period.

Claims:
1. A method of synchronizing message information (208) among a plurality of transceivers (130, 150) comprising the steps of:
transmitting (200) by a wireless messaging infrastructure a first message (205) having a first status;
in one transceiver (130) of the plurality of transceivers, changing (220) the first status of the first message to a second status responsive to an input to the one transceiver, and transmitting (235) a second message (240) indicative of the second status;
in the wireless messaging infrastructure (110), receiving (245) the second message;
and
characterised in that the method includes
the steps of in the wireless messaging infrastructure, responsive to receiving the second message transmitting (250) a third message (255) indicative of the second status; and
in at least one other transceiver (150) of the plurality of transceivers, receiving (265) the third message and responsive to receiving the third message, changing (275) the first status of the first message to the second status;
said step of transmitting (235) the second message indicative of the second status in the one transceiver (130) further comprises the steps of:
delaying (230) transmission of the second message by a predetermined time period after changing (220) the first status of the first message in order to reduce the number of status change transmissions;
changing (220) the second status of the first message to a subsequent status in response to a subsequent input to the one transceiver; and
transmitting (235) the subsequent status as the second status if changing of the second status to the subsequent status occurs within the predetermined time period.

2. A method of synchronizing a status of a plurality of transceivers (530, 550) comprising the steps of:
in a first transceiver (530),
changing (620) the status of the first transceiver from a first status to a second status as a result of an input from a user, and transmitting (635) a first message (640) indicative of the second status;
in a wireless messaging infrastructure (510),
receiving (645) the first message,
characterised in that the method includes the steps of,
in the wireless messaging infrastructure, in response to receipt of the first message transmitting (650) a second message (655) indicative of the second status; and
in a second transceiver (550),
receiving (665) the second message, and changing (675) a status of the second transceiver to the second status in response thereto;
said step of transmitting (635) the first message indicative of the second status in the first transceiver (530) further comprises the steps of:
delaying (630) transmission of the first message by a predetermined time after changing (620) the status of the first transceiver in order to reduce the number of status change transmissions;
changing (620) the status of the first transceiver to a subsequent status responsive to a subsequent input to the first transceiver; and
transmitting (635) the subsequent status as the second status if the changing of the status to the subsequent status occurs within the predetermined time.

3. The method according to claim 2 further characterised by the steps of:
in the first transceiver (550),
receiving (660) the second message; and decoding (660) the second message without further changing the status of the first transceiver.

4. The method according to claim 2 or 3 wherein the first transceiver (530) and the second transceiver (550) have a multiplicity of status categories, each of the multiplicity of status categories having a state, and the first message is a signal indicative of state of status category which has changed in response to the input.
