Abstract
A method and apparatus for allowing a radio control console to failsoft to a predetermined channel assignment plan, without disrupting emergency calls then in progress, upon the failure of a CAD host computer link that would ordinarily provide control signals to the console. Channels are deassigned unless they are supporting an emergency call, and then reassigned to a default assignment. If the reassignment would cause a duplicate assignment, the duplicate assignment is first deassigned prior to making the new default assignment.
Claims12
In a system having:
- first control means for providing a control signal;
- second control means for controlling a plurality of communication paths;
- and
- link means for providing said control signal to said second control means to allow said first control means to influence control of at least some of said plurality of communication paths;
- an improvement comprising:
- response means responsive to detection of a predetermined event for causing said second control means to control said plurality of communication paths in a predetermined manner, with the exception of any communication paths that are supporting communications having at least a predetermined priority when said response means responds to said detection.
3 more elements
In a radio communications system having:
- CAD host computer means for providing a control signal;
- console means for controlling a plurality of radio communication paths;
- and
- link means for providing said control signal to said console means to allow said CAD host computer means to influence control of at least some of said plurality of radio communication paths;
- an improvement comprising:
- response means responsive to detection of a predetermined event for causing said console means to control said plurality of radio communication paths in a predetermined manner, with the exception of any communication paths that are supporting communications having at least a predetermined priority when said response means responds to said detection.
3 more elements
In a system having:
- CAD host computer means for providing a control signal;
- console means for controlling a plurality of radio communication paths;
- and
- link means for providing said control signal to said console means to allow said CAD host computer means to influence control of at least some of said plurality of radio communication paths;
- a method of controlling said plurality of communication paths when a predetermined event occurs, comprising the steps of:
- (A) detecting said predetermined event;
- (B) upon detecting said predetermined event, causing said console means to control said plurality of radio communication paths in a predetermined manner, with the exception of any communication paths that are supporting communications having at least a predetermined priority when said predetermined event is detected.

In a system having:
- CAD host computer means for providing a control signal;
- console means for controlling a plurality of radio communication paths;
- and
- link means for providing said control signal to said console means to allow said CAD host computer means to influence control of at least some of said plurality of radio communication paths;
- a method of controlling said plurality of communication paths when a predetermined event occurs, comprising the steps of:
- (A) detecting said predetermined event;
- (B) identifying any of said radio communication paths that are supporting communications having at least a predetermined priority;
- (C) deassigning at least some of said plurality of radio communication paths, provided that no radio communication paths identified as supporting a communication having at least said predetermined priority are deassigned.
