Abstract
A first off-network mission critical (ONMC) wireless device discovers ONMC wireless devices employing a proximity services discovery procedure. First media traffic is transmitted employing a first mission critical session to a third ONMC wireless device. A message comprising an organization field identifier and an organization identifier is received from a second ONMC wireless device. A call priority is determined, at least in part, based on the organization field identifier and the organization identifier. Transmission of the first media traffic terminates, based at least on the call priority. Transmission of second media traffic to the second ONMC wireless device employing a second mission critical session may be started.
