摘要:
 异构无线网络资源管理中最重要的是网络选择过程。传统的网络选择算法，有时会造成某些网络的拥塞和某些网络资源的浪费。针对这个问题，研究一种网络选择算法，在效用函数中考虑用户业务的QoS等级，然后根据效用值为用户提供适当的接入网络。不同的业务类型及用户的QoS需求是很重要的，不是所有的网络都可以满足用户需求。仿真结果表明，该算法可以提高实时性要求较高的用户满意度，并使不同网络之间可以得到资源的有效利用和负载均衡。
Abstract:
 The most important functions within the Common Radio Resource Management ( CRRM) is the network selection procedure. Some traditional network selection algorithms will lead to network congestion or resource underutilized. In view of this,research a QoS-based network selection algorithm,in which a utility value is assigned to the associated RATs considering the QoS level of user transac-tion. QoS demands of different traffic types is very important. Not all of the network can meet user needs. The simulation results demon-strate the algorithm can improve the higher real-time requirements of customer satisfaction,and can make resources used effectively and load balancing between different network.
