This Recommendation describes the mobility management (MM) framework for interworking between WiMAX and UMTS networks where each access network would be operated by different service providers or different network management systems. In this Recommendation, the functional architecture focuses on IP mobility support for user equipment (UE) moving between those two different access networks. The functional architecture described in this Recommendation may be referred as a building block to be used to extend toward the other wireless access networks in next generation networks (NGNs).
