Group scan in overlapping geofences

Abstract:

The present invention relates to method, system and electronic communications device for providing group scan for mobile devices located in overlapping active geofences. A method comprises, at one of a mobile device and a radio controller device in an infrastructure associated with the mobile device: determining a current location of the mobile device; identifying a plurality of active geofences having definitions that include the determined current location of the mobile device; accessing a geofence mapping that assigns, for each of the identified plurality of active geofences, one of a plurality of different priority levels and one of a plurality of different talkgroups; monitoring each of the plurality of different talkgroups for active calls as a function of the different priority levels; identifying a subset of the plurality of different talkgroups from the plurality of different talkgroups in the geofence mapping having an active call and, for each talkgroup in the subset, a particular talkgroup associated with a highest priority geofence; and joining the mobile device to the particular talkgroup.
