Embodiments allow one or more eNBs that become isolated from core network entities (e.g., evolved packet core entities such as mobility management entity, serving gate way, packet data network gateway, and so forth) to form a resilient mode network. Such a network can function in a limited fashion and provide for UE to UE communications within the resilient mode network coverage area. One or more of the eNBs function as an autonomous eNB and provide a subset of core network functions that allow UE to UE communications within the resilient mode network coverage area. Embodiments disclosed herein select which eNB functions as the autonomous eNB and then the other eNBs establish an S1-MME and/or S1-U interface with the autonomous eNB.
