Abstract: A method and system for retransmitting an emergency message including receiving, at a communication device, the emergency message including a first identifier indicative of a communication type and a second identifier indicative of a type of emergency. An electronic processor of the communication device selects, for distribution of the emergency message, a plurality of communication channels and at least one communication type based on the second identifier. The electronic processor prioritizes the plurality of communication channels and the at least one communication type according to a transmission priority having a higher priority associated with at least one of the group consisting of the first identifier and the second identifier. Then, the electronic processor controls transmission of the emergency message according to the transmission priority over the plurality of communication channels and the at least one communication type.

Abstract: A method and apparatus for maintaining a participation level for a plurality of communication devices assigned to a task group. A server is communicatively coupled to the plurality of communication devices assigned to the task group and defines a minimum quantity of communication devices to be assigned an active executor role for the task group. Communication devices that are assigned the active executor role are locked to the active executor role for the task group when the quantity of communication devices that are currently assigned the active executor role does not exceed the minimum quantity of communication devices to be assigned the active executor role for the task group.

Abstract: A method and apparatus for grouping communications between mobile communication devices. The method includes receiving, at a mobile communication device, one or more facility identifiers, each of the one or more facility identifiers associated with a facility. The method further includes storing the one or more facility identifiers in a memory; decoding, via an electronic processor, a group call having an initiation identifier; and comparing, via the electronic processor, the initiation identifier to the one or more facility identifiers. The method further includes joining, via the electronic processor, the group call based on the comparison between the initiation identifier and the one or more facility identifiers. The method may further include leaving, via the electronic processor, the group call.
