基于云计算的OMS即时通讯系统设计与实现

资源受限的移动设备因其有限的计算能力、存储资源、用户接口等，无法承载3G高带宽环境下丰富的移动网联网应用。通过借鉴云计算强大的计算和存储能力，提出一种“云+端”新型移动网联网应用研发模型：一方面，将复杂的逻辑计算和庞大的存储量交给能力强大的云计算平台处理；另一方面， OMS(open mobile system)作为云计算的“端”平台，能够与云计算平台无缝整合，为用户提供真正意义上的、丰富的、高效的、廉价的移动互联网应用。同时，模型对于高带宽环境下新型移动通信软件研发具有较好的实践和推广价值。

Design and implement of OMS IM system based on cloud computing

Mobile device, as a limited system, does not support new 3G mobile apps. By referring to cloud computing model, a new mobile apps development framework based on cloud platform and cloud terminal was proposed. On the one hand, lots of complex logic computation and enormous storage tasks were carried by cloud computing platform. On the other hand, OMS, which was an end platform of cloud computing, was providing rich, efficient and cheap mobile internet based applications in the real sense. Also, OMS could be integrated with cloud computing platform seamlessly. The novel model shows its values in technical and economical viewpoints of the new mobile communication software in high-bandwidth environment.
