Patent ID: 8634799

Claim:
A method for dynamically reconfiguring subscriber unit (SU) usage of radio access networks, the method comprising: identifying, based at least on a type of incident occurring within a particular geographic area, a first incident response group of SUs having a first higher priority for responding to the incident and a second incident response group of SUs having a second lower priority for responding to the incident; identifying a first higher priority radio access network, of a first network type, having a sufficient coverage level across the particular geographic area and a second lower priority radio access network, of a second network type different from the first, having a sufficient coverage level across the particular geographic area; assigning the first incident response group to the first higher priority radio access network and assigning the second incident response group to the second lower priority radio access network; and instructing first SUs that are members of the first incident response group and not already registered with the first higher priority radio access network to move to the first higher priority radio access network by transmitting a message, via respective radio access networks other than the first higher priority radio access network, to move to the first higher priority radio access network identified in the message.
