Abstract:
1. A method for interfacing a mobile unit with a system that includes a plurality of RF ports and a first cell controller, the method comprising: associating, by the first cell controller, the mobile unit with a first RF port of the plurality of RF ports using at least one security parameter for communicating data signals, wherein the first RF port is associated with the first cell controller; relaying, by the first cell controller, a first data message addressed to the mobile unit to the first RF port for conversion into a first radio message by the first RF port; performing roaming functions by the first cell controller, wherein the roaming functions include receiving, by the first cell controller, a first request message from the mobile unit to roam from the first RF port to a second RF port of the plurality of RF ports, wherein the second RF port also is associated with the first cell controller; associating, by the first cell controller, the mobile unit with the second RF port without changing the at least one security parameter parameter; and relaying, by the first cell controller, a second data message addressed to the mobile unit to the second RF port for conversion into a second radio message by the second RF port.
