Abstract: A device, system and method for determining a prioritized list of communication groups is provided. A computing device monitors current call statistics of a plurality of communication groups, the communication device assigned to the plurality of communication groups. The computing device, based on a comparison of the current call statistics with historical call statistics of the plurality of communication groups, generates a prioritized list of the plurality of communication groups. The computing device transmits, to the communication device, the prioritized list. The communication device may render the list for selection of a communication group, and/or automatically change to a highest priority communication group of the prioritized list, and/or when bandwidth of a current site is unavailable to communicate on the highest priority communication group, roam to a site with available bandwidth to change to a highest priority communication group in the prioritized list.

Abstract: A device, method and system for scanning communication systems of different types is provided. A mobile device comprises: first and second transceivers to communicate first and second communication systems of different types; a memory storing first and second scan lists for scanning first and second channels on the first and second communication systems; and a controller configured to: communicate, using the first transceiver, an indication of the first and second scan lists to a gateway device configured as a proxy for the mobile device to communicate with the first communication systems; receive, using the first transceiver, from the gateway device, a reply indicating that the gateway device is capable of scanning the first communication systems using the first scan list, but is not capable of scanning the second communication systems; and control the second transceiver to scan the one or more second communication systems using the second scan list.
