Research of Multi-connection Technique in Heterogeneous Network
Abstract:In heterogeneous network environment, the development of different radio access technologies promotes multiple connection technology to be a new research hotspot, international standard organizations have already launched related research, mainly contains extension to mobility protocol, multiple system access and flow mobility, etc. Firstly, this paper summarizes the key technologies of multiple connection and analyzes access selection issue of multiple connection, after that this paper proposes a solution of MDP-based access selection with detailed model and impletation, then the simulation experiment is conducted and performance of this solution is estimated; at last, the conclusion is given.
Keywords: Heterogeneous Network Multiple Connection Access Selection MDP
