QUICK RECOVERY OF RF SESSIONS AFTER BACKHAUL LINK FAILURE
First Claim
1. A method comprising:
- detecting, by one or more devices, failure of a backhaul network connecting a cell site to a core portion of a wireless network;
suspending, by the one or more devices and based on the detected failure, a communication session with a mobile device connected to the cell site through radio interfaces, the suspending of the communication session including preventing loss of the communication session despite the failure of the backhaul network;
detecting, by the one or more devices, cessation of the failure of the backhaul network; and
resuming, by the one or more devices and based on the detected cessation of the failure of the backhaul network, the communication sessions with the mobile devices.

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.

9. A device comprising:
-
a memory; and at least one processor to execute instructions in the memory to; detect failure of a backhaul network connecting a cell site to a core portion of a wireless network; 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; 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. - View Dependent Claims (10, 11, 12, 13, 14)

15. A system comprising:
-
a cell site in a wireless network, the cell site coupled to a backhaul network and the cell site including; a failure detection component to detect a failure in the backhaul network, and a session suspension component to suspend, based on the detected failure in the backhaul network, communication sessions with mobile devices that are connected to the cell site in the wireless network; and a core portion of the wireless network, the core portion of the wireless network being coupled to the backhaul network and the core portion of the wireless network including; logic to detect the failure in the backhaul network; and logic to suspend, based on the detected failure in the backhaul network, communication sessions in the core portion of the wireless network that are associated with the mobile devices. - View Dependent Claims (16, 17, 18, 19, 20)
