M2M通信被看作是一种可能没有人际互动的实体与实体之间的通信形式。它面临的一个重大挑战是设备在没有人员值守的情况下的远程管理问题。针对此问题,3GPP标准化组织提出了一种基于可信环境(Trusted Environment,TRE)的M2M设备远程签约信息管理方案和基于通用集成电子卡(Universal Integrated Circuit Card, UICC)的两类解决方案。前者不需要给每一个设备安装UICC,而是可以将重要的认证数据和功能集成在M2M设备上TRE模块里。最后对方案的安伞件和件能作了讲一步研究和说明.
M2M Communication is seen as a form of data communication between entities that may have no human interaction. One of the challenges with M2M communication is that deployed M2M equipments are managed remotely without any direct human interaction with the device. Focused on this problem, 3GPP has proposed a TRE based solution and a UICC based solution. It' s not necessary in the TRE based solution to provide each equipment with UICC, but the important dates and functions can be integrated in the TRE mod- ule. The security and capacity of this solution is further studied and illustrated at last.
