Abstract
A method and device for allocating a channel in a decentralized trunked radio communication system enables efficient channel utilization. The method includes scanning at a first subscriber unit a plurality of channels to determine whether a call of interest to a first subscriber unit is active in the system (step 410). The plurality of channels is then scanned at the first subscriber unit to identify a first channel that is clear in the plurality of channels after determining that there is no call of interest to the first subscriber unit active in the system (step 415). The first subscriber unit is then tuned to the first channel that is clear (step 420).
Claims12
A method for allocating a channel in a decentralized trunked radio communication system, the method comprising:
- scanning at a first subscriber unit a plurality of channels to determine whether a call of interest to the first subscriber unit is active in the system;
- scanning at a first subscriber unit the plurality of channels to identify a first channel that is clear in the plurality of channels after determining that there is no call of interest to the first subscriber unit active in the system;
- and
- tuning the first subscriber unit to the first channel that is clear;
- determining whether a new call is of interest, and participating in the new call on the first channel if the new call is of interest;
- determining whether the new call is of interest, and tuning to a clear channel if the new call is not of interest:
- activating the first subscriber unit before scanning the plurality of channels;
- and
- initiating a new cell at a first subscriber unit on the first channel after tuning to the first channel that is clear,
- wherein the new call is a group call to a first talk group.
An electronic communication device, comprising:
- a processor;
- and
- a non-transitory memory operatively coupled to the processor, wherein the memory comprises:
- computer readable program code components for scanning a plurality of channels to determine whether a call of interest to a device is active in the system;
- computer readable program code components for scanning the plurality of channels to identify a first channel that is clear in the plurality of channels after determining that there is no call of interest to the device active in the system;
- and
- computer readable program code components for tuning the device to the first channel that is clear;
- computer readable program code components for whether a new call is of interest, and participating in the new call on the first channel if the new call is of interest;
- computer readable program code components for determining whether the new call is of interest, and tuning to a clear channel if the new call is not of interest
- wherein the memory further comprises computer readable program code components for activating the device before scanning the plurality of channels and computer readable program code components for initiating a new cell on the first channel after tuning to the first channel that is clear;
- wherein the new cell is a group call to a first talk group.
