摘　　要：移动设备的计算能力、存储能力、网络带宽、电池续航等都非常受限,而且现有的云服务基本没有针对移动设备的上述特点做优化,严重降低了移动设备访问云服务的质量。针对存在的问题,提出了面向移动设备的数据传输格式优化模型和服务Mashup模型,设计并实现了一个基于代理的移动云服务访问框架,使得移动设备通过代理服务器来访问云服务。在4种不同情况下对移动设备的服务请求响应时间、响应结果处理时间、请求响应流量和能耗分别进行了测试,结果表明实现的框架具有一定的实际意义。The mobile devices are usually limited in its computing cabability, storage capacity, network bandwidth and battery life. Existing cloud services are not optimized for those features of the mobile devices. As a result, the quality of the mobile devices to access cloud services is seriously reduced. Aiming at this problem, a data transmission format opti- mization model and a servics mashup model were presented for mobile devices. And a framework of mobile cloud ser- vices access based on proxy was designed and implemented, which enables mobile devices to access cloud services through a proxy server. Under four different situations, the request response time, response process time, bandwidth flow and energy consumption of the mobile devices were tested. The test result shows that this framework has some practical significance.
