英文摘要: Future mobile communication network architecture and its mobility management technologies are investigated based on the concept of software defined network. Firstly, the wireless access network architecture supporting vitualization,multi-service, multi-homing and multiple identification is studied in heterogeneous networks, and integration of mobile communication network with future internet on internetworking,storage and computing are considered.In the new architecture, new services, such as mobile cloud computing service are supported, radio resources, handover among cells and signalling overheads are optimized. Secondly,based on the above architecture, mobility management of general attached objects are researched in view of device, network,content and context.integrated mobility management schemes meeting the demands of users and operators, mobility management performance evaluation and related protocol design are discussed. Thirdly, different semantic aware mobility, routing strategies and related protocol design based on wireless link quality are explored in order to support robost data transmission during disconnection in the enviroment of mobile communication.
