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.

Bearer preference in a combined smart-mic and LMR radio

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.

Integration of physical and virtual LMR networks

Integration of a land mobile radio (LMR) communications system and other wireless IP based systems such as LTE by way of a multi bearer router. The LMR system may be either trunked or conventional. The multi bearer router maintains LMR IDs and also IP addresses for base stations, multi bearer terminals and other components of the integrated system.

Use of a router for integration of LMR and IP networks

A communication system having multiple bearers overlays a relatively narrowband bearer such as P25 on a relatively wideband bearer such as LTE, for transmission of both uplink and downlink signals. The wideband bearer uses a spectrum of subcarriers which form a set of radio frequency blocks. One or more blocks or other related parts of the spectrum may be allocated to the narrowband bearer. In some cases the narrowband bearer may push through the wideband allocation using a relatively high power to dominate signals transmitted by the wideband bearer. Voice calls such as emergency calls using the narrowband bearer may be prioritized.

Overlay of bearers in a radio communication system

A communication system is made up of a number of LMR and IP bearers including LTE and P25. The information flowing over the integrated system is managed according to the situational context of the user. A policy driven approach is described that uses user context as its inputs and converts this into actions that preferentially improves the communication for the user particularly as they move between the available networks.

Policy implementation over LMR and IP networks

A radio system having multiple bearers overlays a relatively narrowband bearer such as P25 on a relatively wideband bearer such as LTE, for transmission of both uplink and downlink signals. The wideband bearer uses a spectrum of subcarriers which form a set of radio frequency blocks. One or more blocks or other related parts of the spectrum may be allocated to the narrowband bearer.
