Abstract: Disclosed herein are methods and systems for talkgroup-state-dependent routing of group data. An embodiment takes the form of a process that includes handling receipt of packet data addressed to a talkgroup by responsively: determining whether the talkgroup currently has an active voice session on a voice channel; if not, then routing the received packet data to the talkgroup on a data channel; and if so, then routing the received packet data to the talkgroup via metadata fields in the voice channel.

Abstract: A method of interoperating link layer encrypted (LLE) and non-LLE communications in a radio network include receiving, at a radio controller (RC), a new call request for an LLE call, determining that there are one or more currently active non-LLE calls, and causing a message to be transmitted on each channel carrying one of the one or more currently active non-LLE calls informing mobile stations (MSs) participating in the non-LLE calls that a new LLE call has been or is-to-be granted. MSs participating in one of the non-LLE calls and receiving the message determine from the message or via a call grant obtained via a control channel, whether the new LLE call is of interest, and if so, switching to a channel assigned to the new LLE call and participating in the new LLE call.
