  • Base stations routing traffic over a packet backhaul network to multiple routing elements
    Patent number: 8804486
    Abstract: System, methods, and networks are disclosed that allow base station systems of a wireless communication network to transmit outgoing traffic over a packet backhaul network to multiple routing elements on the MSC side of the network. A base station system described herein identifies a primary routing element and a backup routing element. The primary routing element is the device to which the base station system transmits outgoing traffic under normal operation, and the backup routing element is an alternate to the primary routing element. To transmit traffic over the packet backhaul network, the base station system monitors the availability of the primary routing element. If the primary routing element is available, then the base station system transmits outgoing traffic over the packet backhaul network to the primary routing element. If unavailable, then the base station system transmits outgoing traffic over the packet backhaul network to the backup routing element.
