Abstract
Communication sessions with mobile devices may be suspended, in a wireless communications network, after failure of one or more backhaul network links In one implementation, a device may detect failure of a backhaul network connecting a cell site to a core portion of a wireless network; and suspend, based on the detected failure, communication sessions with mobile devices connected to the cell site through radio interfaces, the suspending of the communication sessions including preventing loss of the communication sessions despite the failure of the backhaul network. The device may further detect cessation of the failure of the backhaul network; and resume, based on the detected cessation of the failure of the backhaul network, the communication sessions with the mobile devices.
