Abstract:
Various embodiments disclosed herein provide for reestablishing a backhaul connection due a failed connection. According to some embodiments, a system can comprise detecting a failure in a backhaul communication link between a first node device and a second node device, wherein the second node device is communicatively connected to a core network device of a core network, selecting a new node device, other than the first node device and the second node device, that is communicatively connected to the core network device for establishment of a new backhaul communication link to replace the backhaul communication link, and establishing a connection with the new node device to provide a backhaul communication link failure indication to a controller and to request the controller to provide resources to establish the new backhaul communication link with the new node device.
