| 摘 要： | 为了提高异构网络中多模终端选择网络的准确性，提出了一种基于灰度关联和时序多指标判决理论的动态接入选择策略. 通过将接入选择转化为多指标决策问题，从整体上考虑接入选择参数的影响，为用户提供合理的接入选择. 仿真结果表明，该策略能综合考虑多种接入判决指标，并保证移动终端选择最优的网络接入.

| Abstract: | Based on gray relation analysis and multi-criteria decision, a dynamic access selection strategy was proposed to improve the accuracy of access selection for multi-model terminals in heterogeneous networks. By transforming access selection into multi-criteria decision, the effects of access selection parameters were considered comprehensively and an appropriate access network was supplied for the terminals. The simulation results showed that this strategy can provide optimal access networks for multi-model terminals after balancing multiple decision criteria. |
