Methods and systems for simultaneous talking in a talkgroup using a dynamic channel chain
First Claim
1. A method comprising:
- a mobile radio receiving via a user interface a broadcast-start command associated with a talkgroup in which the mobile radio is a participant, the talkgroup having an associated channel set that includes a primary channel and a group of auxiliary channels, the mobile radio having a selectable transmit channel and a selectable receive channel;
the mobile radio, responsive to receiving the broadcast-start command, selecting the primary channel as its transmit channel if the primary channel is inactive, and otherwise selecting an inactive auxiliary channel as its transmit channel;
the mobile radio receiving user media via the user interface, and transmitting received user media on the selected transmit channel;
the mobile radio scanning for a transition of an auxiliary channel from inactive to active; and
the mobile radio, responsive to detecting such a transition on a given auxiliary channel, selecting the given auxiliary channel as its receive channel for receiving inbound media, generating mixed media at least in part by mixing inbound media received on the selected receive channel with user media received via the user interface, and transmitting the mixed media on the selected transmit channel.

Abstract
A mobile radio has selectable transmit and receive channels, and is in a talkgroup that has a primary channel and multiple auxiliary channels. The mobile radio receives a broadcast-start command, and responsively selects its transmit channel to be the primary channel (if available) or an inactive auxiliary channel (if the primary channel is not available). The mobile radio receives user media via its user interface, and transmits that received user media on its selected transmit channel. The mobile radio scans for an auxiliary channel transitioning from inactive to active. Responsive to detecting such a transition, the mobile radio selects that auxiliary channel as its receive channel. The mobile radio mixes inbound media received on its selected receive channel with user media received via its user interface, and transmits the mixed media on its selected transmit channel.

20. A mobile radio comprising:
-
a user interface; a communication interface having a selectable transmit channel and a selectable receive channel; a processor; and data storage containing instructions executable by the processor for causing the mobile radio to carry out a set of functions, the set of functions including; receiving via the user interface a broadcast-start command associated with a talkgroup in which the mobile radio is a participant, the talkgroup having an associated channel set that includes a primary channel and a group of auxiliary channels; responsive to receiving the broadcast-start command, selecting the primary channel as its transmit channel if the primary channel is inactive, and otherwise selecting an inactive auxiliary channel as its transmit channel; receiving user media via the user interface, and transmitting received user media on the selected transmit channel via the communication interface; scanning, via the communication interface, for a transition of an auxiliary channel from inactive to active; and responsive to detecting, via the communication interface, such a transition on a given auxiliary channel, selecting the given auxiliary channel as its receive channel for receiving inbound media, generating mixed media at least in part by mixing inbound media received on the selected receive channel with user media received via the user interface, and transmitting, via the communication interface, the mixed media on the selected transmit channel.
