| Summary: | Aiming at further promoting the multi-mode terminal’s transmission performance and service continuity,a multi-access selection mechanism for multi-mode terminals which exploits the multi-radio transmission diversity of the heterogeneous wireless networks for accessing multiple networks simultaneously and executing parallel transmission was designed.The mechanism applied exponential smoothing method to process the measured parameters;used state transition models to manage access selection strategies of terminal’s multiple network interface cards;adopted utility functions to dynamically balance terminal’s power consumption and transmission speed.Simulation results demonstrate the decrease of unnecessary re-selections,the enhancement of transmission energy efficiency under the premise of the guarantee of terminal’s power consumption and throughput compared with the traditional switched access selection. |
