中文摘要：

社交网络的高速发展对通信平台提出了更高的要求，用户希望通过智能手持终端在与远方朋友保持联系的同时，也能和身边的陌生人分享信息。但现有通信平台客户端、接入点、服务器的模式受到基础设施的限制，不能满足用户日益增长的通信需求。针对该问题，总结传统通信模式的不足，提出一种面向社交网络的智能通信平台构建方法。根据层次化结构实现智能手持终端在互联网接入点不可用或不稳定情况下的应急通信以及通信范围设定。测试结果表明，该平台能较好地实现邻居感知、文件传输等功能，可满足用户的基本社交通信需求。

英文摘要：

The high speed developments of social network present higher requirement of communication platform： Users are expecting to keep in touch with friends from afar and share the information even with strangers passing by. However, the main issue for current communication platform is： Client, access point and server mode is not able to meet the increasing demand of users due to the restrictions of infrastructure. Therefore, an approach for designing social network oriented intelligent communication platform is proposed based on summarizing the shortcomings and insufficiency of traditional modes. By adopting layering structure, it can be used among smart handheld terminals for urgent communication scenarios and communication range setting when Internet access point is unavailable or unstable. Test results show that this platform is able to achieve the functions about neighbor perception, file transmission, etc. when deploying it on the prototype system for validation. It is qualified to satisfy the users＇ social communication demand.
