本文件规定了基于远程访问（RA）服务器的应用框架、设备交互模型、流程和接口以及消息格式，以实现IGRS智能锁设备之间的智能分组、资源共享和服务协作。本文档适用于具有直接网络连接或通过中间网络连接到服务器进行安全验证的智能锁设备。该服务器利用一种方法将未经授权访问这些智能锁的可能性降至最低，同时在家庭、办公室或其他远程环境中保持用户、智能锁设备和RA服务器之间的无缝互操作性。

This document specifies the remote access (RA) server-based application framework, device interaction model, flow process and interfaces, and message formats to achieve intelligent grouping, resource sharing and service collaboration among IGRS smart lock devices. This document is applicable to smart lock devices with direct network connections or connections through an intermediary network to a server for security authentication. This server utilizes a method to minimize the possibility of unauthorized access to these smart locks, while maintaining seamless interoperability among users, smart lock devices and RA servers at home, office or other remote environments.
