终端直连通信(直连通信)技术的引入为提高频谱使用效率、提高系统吞吐量、降低用户设备的能耗、降低运营商的运营成本提供了技术支持，当前的3GPP网络中已经展开了对终端直连通信技术的研究，定义了终端直连通信技术的多种应用场景。当前的网络侧终端直连通信技术的研究中，主要关注的是物理层上建立终端直连通信网络的方法，比如，如何建立两个用户设备之间的终端直连通信网络。
学术界对终端直连通信技术的研究中提出了一个终端直连通信技术的未来应用场景(如图1所示)：将终端直连通信技术与对等网络(P2P)结合，实现直连通信LAN数据共享，这个场景可以在很大程度上提高数据共享和转发的效率，降低网络侧的负载。
但在当前的3GPP标准化过程中，主要关注的是两个用户设备之间如何建立终端直连通信，其依赖于“满足终端直连通信的物理建立条件(如距离足够近)的两个用户设备均可以实现终端直连通信”的假设，而并没有考虑到用户设备的鉴权以及激励问题，既没有考虑终端直连通信中的用户设备是否安全，是否值得信任以进行数据中转传输，也没有考虑数据中转的潜在商业模式问题(激励问题)，没有一个现实的商业模式可以给与实现支持。
因此，需要一种新的技术方案，来解决终端直连通信网络中的信任和激励问题，提高数据共享的安全性，实现物理域网络和业务域网络之间的跨层优化。
