US 2018/0295635 A1 · SYSTEM AND METHOD FOR DYNAMIC CHANNEL ALLOCATION

Abstract

An exemplary system and method for dynamic channel allocation in an LMR system includes using one or more preference indicators to dynamically determine a channel allocation priority to be used for channel allocation when channel allocation requests are received. The preference indicators may include a channel failure indicator (e.g. a channel health indicator based on repeater failures), a channel priority indicator, a radio frequency interference indicator, a high reflected power indicator, an excessive current drain indicator, a loss of backbone communications indicator, and a channel usage indicator. If more than one preference indicator is used, the channel priority ranking may be determined using any of a variety of weightings and prioritizations of the various preference indicators to dynamically generate the channel allocation priority. The dynamic channel allocation system may include one or more site controllers, servers, and/or one or more processors configured to implement the method of dynamic channel allocation.

Dependent claims

A method for dynamic channel allocation in a land mobile radio communication system, the method comprising:

determining one or more preference indicators for one or more channel for use in allocating at least one of the one or more channels;
determining a priority ranking for use in allocating at least one of the one or more channels based at least in part on the one or more preference indicators;
receiving a first channel allocation request to allocate at least one channel of the one or more channel;
allocating a first channel of the one or more channel in response to the first channel allocation request by selecting the first channel of the one or more of channels based at least in part on a then highest ranked channel of the priority ranking used in allocating the one or more channel.

A method for dynamic channel allocation in a land mobile radio communication system, the method comprising:

determining a first preference indicator for a channel for use in allocating the channel, wherein the channel is associated with one or more repeaters of the land mobile radio communication system, and wherein the first preference indicator includes a channel failure indicator for the channel that corresponds to a current operational state of the one or more repeaters associated with the channel;
determining a priority ranking for use in allocating the channel based at least in part on the first preference indicator that includes the channel failure indicator for the channel;
receiving a channel allocation request;
and
allocating the channel in response to the channel allocation request by selecting the channel based at least partially on the priority ranking for allocating the channel being greater than a second priority ranking of a second channel.

A land mobile radio communication system with dynamic channel allocation to provide mobile communications between at least two of a plurality of radio subscriber units, the land mobile radio communication system comprising:

one or more processors configured to provide dynamic channel allocation, the one or more processors configured to:
determine one or more preference indicators for at least one of a two or more channels for use in allocating the at least one of the two or more channels;
determine a priority ranking for use in allocating at least one of the two or more channels based at least in part on the one or more preference indicators;
receive a first channel allocation request to allocate at least one channel of the two or more channels as a control channel;
allocate a first channel of the two or more channels as the control channel in response to the first channel allocation request by selecting the first channel of the two or more channels based on the highest ranked channel of the priority ranking for use in allocating at least one of the two or more channels;
receive a second channel allocation request to allocate at least a second channel of the two or more channels as a traffic channel while the first channel of the two or more channels is allocated as the control channel;
and
allocate a second channel of the two or more channels as the traffic channel in response to the second channel allocation request by selecting the second channel of the two or more channels based on the then highest ranked channel of the priority ranking for use in allocating at least one of the two or more channels.
