摘　　要：随着无线通信技术的发展,公用移动通信网络和专用集群网等多种网络交叉覆盖,形成异构通信网络。因此,研究一种在异构通信网络下的多模通信手机具有实际的应用需求。以Android系统为平台,将3G模组和d PMR模组集成一体,实现一个手机对两种模组的接入控制和切换,实现多模话音和短信业务。在异构网络环境下进行测试,测试结果表明该多模手机能满足异构网络下网络融合的要求,符合预期设计目标。With the development of wireless communication technology,the public mobile communication network and special trunking networks repeatedly cover the same area to form the heterogeneous network.Therefore,the research on the multimode mobile phone in the heterogeneous network has the practical application requirements.Based on Android platform,3G module and d PMR module were integrated to realize the access control and handover of a single mobile phone to the two modules,as well as the multimode voice and short message services.The tests were conducted in the environment of heterogeneous network.Results demonstrate that the multimode mobile phone not only meets the requirements of the network integration,but accords with the expected designing goal.
