A combined cellular smart-mic and LMR radio terminal is operated to give preference to one wireless bearer over the other. A voice call is often received both on the cellular bearer and the LMR bearer. It is then determined if the cellular or LMR bearer is preferred for calls. The call continues on the preferred bearer only while the same call on the non-preferred bearer is discontinued. The non-preferred call can be muted, disabled or ended for example. The preferred bearer may be determined by signal quality, user location, network priority or user settings, for example.

Integration of a land mobile radio (LMR) communications system and other wireless IP based systems such as LTE by way of a virtual router and virtual base stations. The LMR system may be either trunked or conventional. The virtual router maintains LMR IDs and also IP addresses for both physical and virtual base stations, multi bearer terminals and other components of the integrated system. Physical LMR base stations form a physical network. Virtual LMR base stations form a virtual network. These physical and virtual LMR networks communicate using ISSI, AIS or DFSI for example.
