An integration architecture to 4^Th generation wireless networks

Integration architecture will play a key role in implementing the 4G network to provide the Always Best Connected services. This paper analysis the current communication business model, and get a conclusion that the Mobile Virtual Network Operator (MVNO) can be a good candidate to integrate the multiple radio access networks. The integration can be realized step by step to adapt the user's gradually increased service requirements. We analysis the characters of the MVNO, summarize the required management functions and propose an integration architecture that allows the MVNO to support real time resource management and seamless service handover in the heterogeneous wireless networks. The integration architecture, which is a variation of hybrid network model, requires the least modification of the current access networks.
