ABSTRACT:
Digitally trunked radio transceivers are permitted to roam over an extended coverage area including two or more digitally trunked radio frequency communication networks. Each network includes at least one digital repeater site having a corresponding site coverage area and serving digitally trunked radio transceivers disposed within or near the site coverage area. Each network also includes a local multisite switch for routing communications between the digital repeater sites within the networks. Site adjacency information is established for each site and communicated between the networks. Each digitally trunked transceiver maintains a site adjacency list for its currently selected site and modifies that list when the transceiver roams into a new site coverage area and selects a new repeater site.
