Automatic equivalent temporary talkgroup assignment in a roaming trunking environment
First Claim
Patent Images
1. A method for a roaming communication unit to associate automatically with at least one talkgroup in a second trunked communication system that is equivalent to at least one talkgroup in a first trunked communication system, comprising the steps of:
- (A) determining that communication with a resource controller in the first trunked communication system has been lost;
(B) providing a communication unit composite ID of the roaming communication unit to a second resource controller;
(C) receiving at least one equivalent roaming temporary talkgroup assignment ID;
(D) storing the at least one equivalent roaming temporary talkgroup assignment ID;
(E) operating, thereafter, in the second trunked communication system under the at least one equivalent roaming temporary talkgroup assignment ID until a predetermined event occurs.

Abstract
A trunked communication system utilizes talkgroup synchronization for roaming communication units. By automatically matching the communication unit'"'"'s talkgroup in a first area-wide system with an talkgroup in a second area-wide system, the communication system facilitates rapid association with a desired talkgroup.

12. A method for a roaming communication unit to associate automatically with at least one talkgroup in a second trunked communication system that is equivalent to at least one talkgroup in a first trunked communication system, comprising the steps of:
-
(A) determining that a roaming communication unit utilizing a talkgroup in a first trunked communication system desires to communicate with an equivalent roaming temporary talkgroup in a second system; (B) providing a communication unit composite ID of the roaming communication unit to a second resource controller; (C) determining that an equivalent roaming temporary talkgroup is available in a second system that the communication unit is capable of receiving; (D) receiving at least one equivalent roaming temporary talkgroup assignment ID; (E) storing the at least one equivalent roaming temporary talkgroup assignment ID; (F) operating, thereafter, in the second trunked communication system under the at least one equivalent roaming temporary talkgroup assignment ID until a predetermined event occurs. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. In a network of trunked communication systems constructed and arranged to support communication units roaming from system to system and having a resource controller computer for communicating with at least two trunked communication systems, and each of the at least two trunked communication systems having:
-
one or more trunked repeaters; resource controller means for allocating said one or more trunked repeaters among a plurality of communication units, and for communicating information with at least some of the one or more trunked repeaters, and including means for transmitting a predetermined code word on the selected one of the one or more trunked repeaters; means for communicating with the resource controller means and for assigning identification codes to roaming communication units; and means for interfacing with an unrelated communication network, a method for a roaming communication unit to associate automatically with at least one temporary talkgroup in a second trunked communication system that is equivalent to at least one talkgroup in a first trunked communication system, comprising the steps of; (A) determining that communication with the first trunked communication system has been lost; (B) providing a composite ID of the roaming communication unit to the resource controller in the second trunked communication system; (C) receiving at least one equivalent roaming temporary talkgroup assignment ID; (D) storing the at least one equivalent roaming temporary talkgroup assignment ID; and (E) operating, thereafter, in the second trunked communication system under at least one equivalent roaming temporary talkgroup assignment ID until a predetermined event occurs. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
