Mobile network security needs more attention to meet new emerging situations and applications that use modern technologies such as Device to Device (D2D) communications. One of these situations is getting the connection back securely between out of coverage (OoC) stations and the core network. This paper proposes a framework to reestablish this connection by using some of in-coverage stations, which are located at the edge of the injured area. The framework uses Software-defined Network (SDN) architecture. The local controllers (LCs), within SDN, plan the communications by selecting cluster heads (CHs) inside the injured area to begin D2D communications between these stations and the CHs, under the authority of the core network. In our framework, an effect of Free Riding Attack (FRA) can be mitigated. In addition, the privacy of user entity (UE) is achieved by decoupling the transmitted ID and the ID which is used in calculations. Furthermore, we accomplish secure connections between OoC UEs and the core network, with many security objectives such as data origin authentication, entity authentication and other security goals.
