With the addition of an IAN mode of operation to the handset, MCC task 1902 take on several functions. For example, MCC task 1902 performs system determination that includes IAN systems as well as CDMA, as well as service quality monitoring of CDMA and IAN systems. MCC task 1902 performs active hand-off determination between IAN and CDMA systems, and also performs state transfer of Mobility Management information between the CDMA and IAN services during active hand-off.
