ABSTRACT:
A system and method for priority dispatch communications are provided. Priority access to the communication network is provided. Additionally, barge-in for active dispatch communications in a publicly-accessible network are provided. When the user is in an active dispatch communication with another communication station, and a dispatch communication request from a second communication station is received, it is determined whether a priority value of the second communication station is higher than a priority value assigned to the user or the other communication station. When the priority value for the second communication station is higher, the dispatch communication between the user and the other communication station is suspended, and a dispatch communication is established between the user and the second communication station.
